`
`RESPONSE
`
`In response to the Examining Attorney's office action dated October 19, 2006,
`Applicant attaches both a substitute specimen showing use of the mark in Class 009 and
`the following declaration under 37 C.F.R. Section 2.20 verifying that Applicant has used
`such specimen in commerce since at least as early as May 31, 2005, which duplicates the
`use date listed in the original application filed with the U.S. Trademark Office on June 3,
`2005.
`
`Applicant submits that the attached specimens are acceptable evidence of actual
`use because they meet the requirements of 37 C.F.R. 2.56 as documents which are
`associated with the goods or their sale. 37 C.F.R. 2.56 specimens that "the specimens
`shall be
`labels, tags, or containers
`(or if the nature of the goods make use of such
`specimens impracticable then on documents associated with the good or their sale "
`(emphasis added).
`
`

`
`In the present case, a significant amount of technical information is required to
`connect, install and start up the equipment, in order to use the machines. Operator's
`manuals, such as the specimens, provide infonnation necessary for use of the goods.
`These manuals are fiirther required after purchase to provide both use and maintenance
`information. They provide, therefore, an ongoing association between the goods and the
`mark.
`
`The undersigned, being hereby warned that willful false statements and the like so
`made are punishable by fine or imprisonment, or both, under 18 U.S.C. 1001, and that
`such willful false statements and the like may jeopardize the validity of the application or
`document or any registration resulting therefrom, declares that the facts set forth in this
`application are true; all statements made of his own knowledge are true; and all
`statements made on information and belief are believed to be true.
`
`In light of the above, Applicant believes the mark in question is in condition to be
`approved for publication in the Official Gazette, and such action is respectfully requested.
`In the unlikely event that the Examining Attorney does not find the arguments acceptable,
`Applicant has filed a Notice of Appeal with the Trademark Trial and Appeal Board.

`SAFETY
`
`BEFORE ATTEMPTING ANY PROCEDURE IN THIS
`BOOK, READ AND UNDERSTAND ALL THE SAFETY
`INFORMATION CONTAINED IN THIS SECTION.
`IN
`ADDITION, ENSURE ALL INDIVIDUALS WORKING
`WITH YOU ARE ALSO FAMILIAR WITH THESE
`SAFETY PRECAUTIONS.
`
`For your safety Warning and Information Decals have
`been placed on this product to remind the operator
`to take safety precautions. It is important that these
`decals are in place and are legible before operation
`begins. New decals can be obtained from Sno-Way or
`your local dealer.
`
`the best
`is
`REMEMBER The careful operator
`operator. Most accidents are caused by human error.
`Certain precautions must be observed to prevent the
`possibility of injury to operator or bystanders and/or
`damage to equipment.
`
`NEVER operate Plow when under the influence of
`alcohol, drugs or other medications that could hamper
`your judgement and reactions. An accident may result in
`serious injury or death to other persons or yourself.
`
`ALWAYS operate vehicle in a well-ventilated area. The
`carbon monoxide in exhaust gas is highly toxic and can
`cause serious injury or death.
`
`NEVER allow hands, hair or clothing to get near any
`moving parts such as fan blades, belts and pulleys. Never
`wear neckties or loose clothing when working on the
`vehicle.
`
`NEVER wear wrist watches, rings or other jewelry when
`working on the vehicle or individual equipment. These
`things can catch on moving parts or cause an electrical
`short circuit that could result in serious personal injury.
`
`ALWAYS wear safety goggles when working on the
`vehicle to protect your eyes from battery acid, gasoline,
`and dust or dirt from flying off of moving engine parts.
`
`ALWAYS be aware of and avoid’ contact with hot
`surfaces such as engine, radiator, and hoses.
`
`ALWAYS wear safety glasses with side shields when
`striking metal
`against metal!
`In
`addition,
`it
`is
`recommended that a softer (non-chipable) metal material
`be used to cushion the blow. Failure to heed could result
`
`in serious injury to the eye(s) or other parts of the body.
`
`NEVER allow children or unauthorized person to
`operate this unit.
`
`NEVER exceed 45 m.p.h. when snow plow is attached
`to vehicle. Braking distances may be increased and
`handling characteristics may be impaired at speeds
`above 45 m.p.h.
`
`ALWAYS lock- the vehicle when unattended to prevent
`unauthorized operation of the plow.
`
`ALWAYS check the job site for
`obstructions and people.
`
`terrain hazards,
`
`NEVER exceed 10 m.p.h. when plowing. Excessive
`speed may- cause serious
`injury and damage of
`equipment and property it"an unseen obstacle is
`
`encountered while plowing.
`
`ALWAYS position blade so it does not block path of
`headlamps beam. Do not change blade positions while
`traveling. An incorrect plow position blocking headlamp
`beam may result in an accident.
`
`check surrounding area for hazardous
`ALWAYS
`obstacles before operating this unit.
`
`ALWAYS inspect the unit periodically for defects. Parts
`that are broken, missing or plainly worn must be replaced
`immediately. The unit, or any part of it should not be
`altered without prior written approval of the manufacturer.
`
`ALWAYS insert the cylinder lock when plow is not in
`use.
`lf the cylinder lock is not installed, the plow blade
`could inadvertently drop and cause serious injury.
`
`the vehicle engine, place the
`off
`ALWAYS shut
`transmission in Neutral or Park, turn the ignition switch to
`the “OFF” position and firmly apply the parking brake of
`the vehicle before attaching or detaching the blade from
`the vehicle or when making adjustments to the blade.
`
`ALWAYS inspect lift system bolts and pins whenever
`attaching or detaching the plow, and before traveling.
`Worn or damaged components could result in the plow
`dropping to the pavement while driving, causing an
`accident.
`
`ALWAYS keep hands and feet clear of blade and A-
`Frame when attaching or detaching plow.
`
`NEVER place fingers in A-frame or mount lug holes to
`check alignment when attaching snow plow. Sudden
`motion of the plow could severely injure a finger.
`
`NEVER stand between the vehicle and blade or directly
`in front of blade when it
`is being raised,
`lowered or
`angled. Clearancebetween vehicle and blade decreases
`as blade is operated and serious injury or death can
`result from blade striking a body or dropping on hands or
`feet.
`
`NEVER work on the vehicle without having a fully
`serviced fire extinguisher available. A 5 lb or larger CO?
`or dry chemical unit specified for gasoline, chemical or
`electrical fires, is recommended.
`
`NEVER smoke while working on the vehicle. Gasoline
`and battery acid vapors are extremely flammable and
`explosive.
`
`NEVER use your hands to search for hydraulic fluid
`leaks; escaping fluid under pressure can be invisible and
`can penetrate the skin and cause a serious injury! if any
`fluid is injected into the skin, see a doctor at once!
`Injected fluid MUST BE surgically removed by a doctor
`familiar with this type of injury or gangrene may result.
`
`REMEMBER it" is the owner’s responsibility for
`communicating information on the safe use and
`proper maintenance of this machine.

`
`THEORY OF OPERATION
`
`Hydraulic Power Unit
`
`The hydraulic power unit consists of:
`12VDC Motor
`
`Hydraulic pump rated at 1.54 GPM @ 1500 PS1
`1.35 quart capacity reservoir
`Fine mesh intake filter
`
`Filter screens on all outlet ports
`
`The fluid supply line for the pump is submerged in the
`hydraulic fluid reservoir and is equipped with a fine mesh
`intake filter screen.
`
`The 12VDC motor is protected electrically by a 150 Amp
`circuit breaker located between the battery and the motor
`solenoid.
`‘
`
`The hydraulic pump is protected by a 2100 PSI system
`relief valve.
`
`This unit may be equipped with a Down Pressure Option
`which will allow the operator to selectively switch the
`system to provide additional hydraulic force to the cutting
`edge of the plow.
`
`IMPORTANT: The electric coils, which operate the
`solenoid valves, require a minimum of 9-1/2 volts DC
`for proper operation. Lower voltage will cause erratic
`operation, or failure to operate.
`
`Hydraulic Controls
`
`The hydraulic controls consist of:
`
`System pressure relief valve, set to 2100 PSI.
`Two crossover relief valves, set to 1750 PSI.
`Two wing relief valves, set to 2150 PSI.
`Four three-way two position hydraulic valves and four
`pilot operated check valves for wing angling functions.
`Two double acting hydraulic cylinders for wing angling
`functions.
`
`One three-way two position, three two-way two position
`valves and two check valves for raise, lower and down
`pressure functions.
`One down pressure relief valve.
`
`Electro-Hydraulic Controls
`
`All hydraulic functions are controlled by the 12VDC
`electrical system which actuates coils on the hydraulic
`valves and the solenoid for the electric motor of the power
`unit. 12VDC power is fed from the battery post of the
`motor start solenoid to a control circuit board on the plow
`and from the circuit board to each coil. Each valve is
`
`actuated by completing a circuit to ground through the
`coil, and through the circuit board by means of a wire
`transmitted signal to the circuit board from the hand—held
`controller in the vehicle.
`
`Raise Mode of Operation
`
`Actuating the ‘Raise’ switch on the hand-held controller
`sends a signal to the control circuit board on the plow
`which then actuates the motor solenoid and the coils for
`the ‘C’ valve and ‘F’ valve. Actuating the start solenoid
`sends current to the power unit motor to cause the power
`unit
`to pump hydraulic fluid. Hydraulic fluid, under
`pressure,
`is directed through the ‘C’ valve to the lift
`cylinder causing it to extend and raise the plow. The 'F’
`valve is also actuated to allow fluid in the rod end of the
`double acting raise cylinder to return to the reservoir.
`When the ‘Raise’ switch on the hand-held controller is
`released the start solenoid circuit is broken and the motor
`stops, the circuit to the coil for the ‘C’ valve and the ‘F’
`valve is broken and these valves got to their normally
`closed positions.
`
`Lower Mode of Operation - Gravity Down
`and Float
`
`Actuating the ’Lower’ switch on the hand-held controller
`sends a signal to the control circuit board on the plow
`which then actuates the coil for the ‘B’ valve- and the ‘F’
`valve allowing hydraulic fluid to flow from the lift cylinder
`to the reservoir. Once the ‘Lower’ switch has been
`actuated, the system will stay in this mode until the raise
`function is actuated, allowing hydraulic fluid to flow
`between the reservoir and the lift cylinder and let the lift
`cylinder extend and retract as necessary to follow ground
`contours while plowing.
`
`Lower Mode of Operation — Down Pres-
`‘ sure (DP) System
`
`This system operates only when the ‘DP’ switch and the
`‘Lower’ switch on the hand-held controller is actuated.
`
`Actuating the ‘DP’ switch (a red LED will be lit) actuates
`the pressure switch, the ‘B’ valve coil, the ‘E’ valve coil
`and, through the pressure switch, the start solenoid as
`required. When the ‘E’ valve is actuated and the hydraulic
`pump operates, hydraulic fluid is directed to the rod end of
`the lift cylinder compressing the cylinder and forcing the
`plow down. The pressure switch i_n this system senses the
`pressure of the fluid in the lift cylinder and closes when the
`pressure becomes low, allowing the motor and the pump
`to pump fluid into. the rod end of the cylinder. When the
`pressure reaches the proper level,
`the switch opens,
`shutting off the motor and pump. The system is protected
`by a relief valve which relieves excess pressure it the plow
`is forced up, such as by "a bump or obstacle in the
`roadway. Once any obstacle is cleared, the plow can
`return to a lower position lowering the pressure in the
`system.
`If
`the pressure is
`lowered sufficiently,
`the
`pressure switch will then sense the lowered pressure and
`cause the pump to pump fluid into the system and return
`it to the proper pressure.
`
`

`
`The down pressure system is overridden any time the
`plow control is placed in the ‘Raise’ mode, but will resume
`when placed back into the ‘Lower’ position.
`
`Also, note that the ‘E’ valve is deactivated anytime an
`angle function is activated, but returns to it’s previous
`condition as soon as the angle function is completed.
`
`Circuit Breaker
`
`A 150 Amp circuit breaker is located near the battery in
`the primary 12VDC positive power circuit and is in place
`to protect the motor of the hydraulic power unit. A high
`amp draw condition will cause the breaker element in the
`circuit breaker to interrupt flow to the motor. The circuit
`breaker will automatically reset after it cools down.
`
`Wing Angling Mode of Operation
`Independent Wing Angling
`
`or
`forward
`angled
`can be
`Each wing
`independently by operating the forward or
`switch for either the right or left wing.
`
`ream/ard
`rearward
`
`Operating the right extend switch on the controller will
`energize the motor solenoid and the ‘A’ coil, which will
`allow hydraulic oil under pressure to be directed too the
`base end of the right wing cylinder. Operating the right
`retract switch on the controller will energize the motor
`solenoid and the ‘D’ coil, which will allow hydraulic fluid
`under pressure to be directed to the rod end of the right
`wing cylinder. Operating the left wing extend switch will
`perform the same function as the right except that the ’G’
`coil will be energized instead of the ‘A’ coil. Operating the
`left retract switch will perform the same function as the
`right retract except that the ’H’ coil will be energized
`instead of the ‘D’ coil.
`
`Combination Wing Angling
`
`Both wings can be moved together using the control
`switches on the controller. Operating the forward
`combination switch on the controller will extend both
`
`wings in the ‘scoop’ position. Operating this combination
`will energize the motor solenoid and both the ‘A’ and ’G’
`coils.
`
`Operating the reanlvard combination switch on the
`controller will retract both wings into the ’V’ position.
`Operating this combination switch will energize the motor
`solenoid and both the ‘D’ and ’H’ coils.
`
`Operating the right side combination switch on the
`controller will extend the left wing and retract the right
`wing to plow all snow to the right. Operating this
`combination switch will energize the motor solenoid and
`both the ‘D’ and ’G’ coils.
`
`Operating the left side combination switch on the
`controller will extend the right wing and retract the left
`wing to plow all snow to the left. Operating this
`combination switch will energize the motor solenoid and
`both the ‘A’ and ’H’ coils.
`
`Each wing angling circuit is protected by a crossover relief
`valve set to relieve pressure on the wing angling circuit at
`17850 PSI. Each wing also has a relief valve set at 2150
`P l.

`Operating Classes
`
`28V Series
`
`PLOWING OPERATION
`10. If ballast is required position ballast behind rear
`wheels for optimum performance.
`
`The 28V Series Sno—Way plow is specifically designed for
`heavy duty snow plowing with full size 3/4 and 1 ton 4x4's.
`
`NOTE: The loaded vehicle, including any ballast weight
`and optional equipment, must not exceed the Gross Vehi-
`cle Weight (G VW) or front or rear Gross Axle Weight
`(GA W) ratings specified on the Safety Compliance Certi-
`fication Label located on the drivefs side door opening.
`
`NOTE: All vehicles that are equipped with Sno- Way snow
`plows should be equipped with all vehicle manufacturer's
`recommended options for snow plowing.
`
`For additional information, refer to your dealer and the
`Sno-Way Application Guide
`for
`proper
`vehicle
`applications.
`
`Before.The Season Begins
`
`1. Inspect vehicle safety equipment for proper
`operation; brakes, headlights, plowing lights, windshield
`wipers, flashers, etc.
`
`2. Inspect the plow, plow frame and all attaching
`hardware for wear and corrosion. Replace worn or
`damaged parts and clean and repaint exposed metal
`parts with a high quality, corrosion resistant enamel.
`
`3. Inspect all fasteners to insure that they are properly
`tightened.
`If any fasteners are loose, re-tighten to the
`proper torque (refer to the Torque Specification Chart in
`this manual) and carefully inspect the adjacent area for
`damage or wear as well as carefully inspecting all
`adjacent fasteners for proper torque.
`
`4. Apply a small amount of light oil to the hitch pins and
`pivots,
`to pivot pins between the A-frame and center
`blade assembly, between lift and swing cylinder pivot pins
`and the lift linkage pivots.
`'
`
`5. Check the wing pivots for free movement of the wings
`on the pivot shafts. Lubricate the wing pivot shafts with a
`good quality lightweight HP Lithium based grease.
`
`6. For extremely cold weather plowing, continuous sub
`zero operation, an alternative is to remove the grease
`fittings and fill the grease cavity with SAE 140 gear oil,
`and then replace the grease fitting.
`
`7. Check the reservoir oil level (see maintenance
`instructions) and repair any oil leaks and worn hoses.
`
`Transporting Vehicle With
`Blade Attached
`
`OR DEATH.
`
`Ensure ignition switch is OFF before installing
`or
`removing
`the
`cylinder
`lock
`clamp.
`Equipment failure or inadvertent operation of
`the control switches could allow the plow blade
`to fall, resulting in serious injury.
`
`FAILURE TO FOLLOW CAN RESULT IN INJURY
`
`1. Always install the cylinder lock clamp when the plow
`blade is raised and the operator is not engaged in
`plowing operations.
`
`NOTE: If cylinder lock clamp is not installed during trans-
`port equipment failure or inadvertent operation of the
`control switches while driving could allow the plow blade
`to fall.
`
`2. Always transport the plow with the wings fully folded
`to the rear to keep the transport width to a minimum.
`
`40° F.
`
`Remove the plow when driving extended
`distances at temperatures above 40° F, the plow
`blocks enough airflow to the vehicle’s radiator
`to cause it to overheat at temperatures above
`
`3. DO Not exceed 45 m.p.h. when driving with the snow
`plow attached. Braking distance is
`increased and
`handling is impaired dramatically at speeds above 45
`m.p.h.
`
`8. Inspect electrical connectors. Make sure the contacts
`are clean, and apply a small amount of dielectric grease.
`
`4. Reduce speed when crossing railroad tracks or when
`road conditions deteriorate.
`
`9. Install plow lights and ensure they are aimed properly
`(with plow in full UP position).
`
`5. Never change blade angle or height while driving.
`
`
`
`

`
`6. Position the blade out of the beam path of the
`headlights before driving.
`
`7. Inspect plow and plow attaching hardware for wear or
`damage
`before
`transporting
`and
`beginning
`plow
`operations.
`
`Plowing Like A Pro
`
`2. Plow with the storm. The “Pros” are out early
`removing only several inches of snow at a time. Allowing
`snow to accumulate to unmanageable levels can cause
`difficult removal problems and can be costly in terms of
`"wear and tear" on equipment. The plow is not a “Ram or
`Bulldozer’, if used properly, it will give you many years of
`safe and reliable service.
`
`3. Research municipal ordinances for restrictions on the
`disposal of snow. Many municipalities do not allow snow
`to be placed in roads or throughway.
`
`- Never exceed 10 m.p.h. when plowing! Serious
`
`personal injury can result, as well as damage
`to equipment and property,
`if an unseen
`
`obstruction is encountered while plowing.
`
`- Never plow with your head protruding from the
`vehicle side window. Serious head or neck
`
`injuries can result
`
`from sudden stop
