General

• Before operating, perform a through visual inspection of the equipment. Look for fluid leaks, cracked, bent or broken components, loose nuts, bolts or attachments and proper fluid levels.

• A clean system is essential to long pump life and proper performance.

IMPORTANT: Hydraulic fluid packaged with power unit is Type 5606. If additional oil is added it must be compatible with Type 5606. If another type of oil has been used in the system the same type of oil must be used for topping off the system.

• Do NOT use synthetic oil.

• Oil must contain an anti-foam additive.

• Ensure all electrical connections are clean and tight.

• To prevent rust from forming, clean and repaint exposed metal surfaces

• NEVER operate the equipment with the protective covers or guards removed.

Break In Period

The plow will go through a break in period during which the A-frame and swing frame will settle in. After 15-20 hours of operation check for free play of the A-frame and swing frame pivot.

1. Raise the plow and install the transport lock. See "Installing the Cylinder Lock Clamp" on page 11.

2. Push down on end of blade as far as it will go on the right or left side. Measure and record the distance from the ground to the bottom edge of the wear strip

3. Pull upwards on the same end of the plow as far as it will go. Measure and record the distance from the ground to the bottom edge of the wear strip.

4. Subtract the two measurements. If the number is greater than 1-1/2" then the free play needs to be adjusted.

To Remove Excessive Free Play

1. Tighten the pivot bolt nut (typically 1/6 to 1/3 turn, one or two flats).

Periodic Inspection

After every 20 hours of operation perform the following inspections:

1. Inspect plow assembly including sub frame for any damage or excessive wear. Replace parts as necessary

2. Inspect all fasteners to insure they are properly tightened. Re-tighten loose fasteners to the proper torque (Refer to torque specification chart in this manual).

3. Apply a small amount of light oil to: Quick-tatch pin and handle assemblies, pivot pins between the blade and swing frame, and pivot pins at lift and swing cylinders. Also lubricate jackstand pins. (See Figure 2-1).

Figure 2-1

4. If wear is noticed between the A-frame and the swing frame apply a good quality anti-seize lubricant to this area.

Plow Storage

When storing the plow for long periods of time use the following guidelines.

1. If the plow will not be stored on pavement, place a board under the jack stand to prevent it from sinking into the ground

2. To prevent corrosion, coat the exposed portion of the cylinders with light grease.

Grease all pivot points.

3. Fill hydraulic reservoir to the fill line to minimize trapped air.

4. Place dielectric grease on the terminals of all electrical plugs. Make sure protective caps are in place.

Cutting Edge

NOTE: Note: Cutting edge must be replaced when it is worn to the bottom edge of the frame.

1. Raise the plow to full up position.

2. Install cylinder lock clamp.

3. Lower plow onto cylinder lock clamp

1. The blade skin must be retained prior to removing cutting edge. This can be done using a pair of 6" C-clamps located at the center of the curved portion of the blade.

2. Remove mounting bolts holding old cutting edge to blade. Discard old cutting edge and hardware.

3. Consult parts manual for proper replacement cutting edge.

7. Install new cutting edge using new hardware.

Disk Shoe Adjustment

1. Raise plow to full up position.

2. Install cylinder lock clamp.

3. Lower plow onto cylinder lock clamp.

1. Turn vehicle ignition switch and plow control OFF and apply emergency brake.

2. Adjust shoe assemblies by removing shoe mounting lynch pin and adding or subtracting washers on the top or bottom of the shoe-mounting bracket. (See Figure 2-5).

Figure 2-5

6. After the disk shoe position is properly adjusted place washer on the shoe stem - above the disk shoe mounting bracket and below the retaining lynch pin - to remove all up and down movement of the disk shoe in the bracket. Failure to do so will result in excessive wear of the holes in mounting bracket or bending of the disk shoe stem.

IMPORTANT: Snap lynch pin ring over so that it contacts the pin. If ring does not contact lynch pin, rotate the pin and reverse the direction of the ring. If the ring does not contact the pin it is not locked and could fall out.

Trip Spring Adjustment

Operating Class

The 29 series Sno-Way plow is specifically designed for heavy commercial applications on 3/4 and 1-ton trucks.

The 32 series Sno-Way plow is specifically designed for heavy commercial applications on trucks with a GVWR of 10,000 to 19,000 lbs. The 8½’ and 9’ blades can also be installed on many 3/4 ton trucks.

Before the Season Begins

1. Inspect plow vehicles brakes, headlights, plowing lights, windshield wipers, flashers, electrical system, and cooling system for proper operation.

2. Inspect plow assembly including sub frame for any damage or excessive wear. Replace parts as necessary

3. Inspect all fasteners to insure they are properly tightened. Re-tighten loose fasteners to the proper torque (Refer to torque specification chart in this manual).

4. Apply a small amount of light oil to: Quick-tatch pin and handle assemblies, pivot pins between the blade and swing frame, and pivot pins at lift and swing cylinders. Also lubricate jackstand pins. (See Figure 2-1).

5. If wear is noticed between the A-frame and the swing frame apply a good quality anti-seize lubricant to this area.

6. Clean and repaint any exposed metal parts with corrosion resistant enamel.

7. Check free play between the a-frame and swing frame pivot. Adjust if necessary. ( See “Break In Period on page 14).

8. Check the oil level and repair any oil leaks. (See “MAINTENANCE on page 14).

9. Inspect electrical connectors. Make sure the contacts are clean, and apply a small amount of dielectric grease.

10. Install auxiliary and flashing lights (if not equipped). Ensure auxiliary lights are aimed properly (with the plow raised).

11. If ballast is required, position and secure ballast behind rear wheels, for optimum performance.

Transporting Vehicle With Plow Attached

1. Always install the cylinder lock clamp when the plow is raised and the operator is not engaged in plowing operations.

NOTE: If cylinder lock clamp is not installed during transport equipment failure or inadvertent operation of the controls could allow the plow to fall.

1. Position the blade out of the beam path of the headlights before driving.

2. Do not exceed 45 M.P.H. when driving with the snowplow attached. Braking distance is increased and handling impaired at speeds above 45 M.P.H.

3. Reduce speed when crossing railroad tracks or when road conditions deteriorate.

Never change blade angle or height while driving.

4. Inspect plow and attaching hardware for damage before transporting or plowing.

	WARNING
The 32 Series blade will partially block the plow lights when fully raised. Always lower plow unto lift cylinder lock clamp when transporting plow at night. Blocked plow lights could result in an accident. FAILURE TO FOLLOW CAN RESULT IN INJURY OR DEATH

Plowing Like A Pro Using The Down Pressure (DP) Hydraulic

NOTE: The air bag is factory set to deploy at a certain acceleration level. The air bag will deploy with the plow attached if an obstruction is hit with enough force to reach this level. Always plow within the recommended plowing speeds and know the area you are plowing to avoid any obstructions.

NOTE: For better clean up of hard packed snow; raise the disc shoes so that the cutting edge of the blade comes into direct contact with pavement. Use the lowest possible gear to place maximum power behind the cutting edge.

For instructions on using the plow controller to manipulate the plow see the manual included with your plow control package.

1. Become familiar with the area to be plowed and mark potential hazards before the snow falls. Many immovable objects cannot be seen when covered with snow. Developing a plan early can save valuable time and equipment damage. Allow sufficient room to pile snow, out of the traffic area, with enough space for when the next storm comes.

2. Plow with the storm. The "Pros" are out early removing only several inches at a time. Allowing snow to accumulate to unmanageable levels can cause removal problems and wear and tear on equipment. The plow is not a "Ram" or a "Bulldozer". If used properly, it will give 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 or moved across roads or highways.

4. Research state department of transportation rules on maximum width restrictions for snow plows. Certain blades may require permits.

Systems

The DP system was designed for removing hard packed snow from hard surfaces that has been driven on prior to plowing.

The system should be turned OFF when plowing surfaces such as gravel, dirt, sand, etc., to prevent cutting into the surface.

Activating the system applies down pressure to the down pressure side of the lift cylinder. This down pressure will force the cutting edge through hard packed snow. If down pressure decreases as a result of a low spot, more down pressure will be applied to the lift cylinder. When a high spot is encountered the down pressure will be relieved to allow the plow to follow the contour without lifting the front of the truck.

Clearing Driveways

1. Head into driveway with the blade angled to move snow away from buildings. Continue to widen the drive path by rolling snow away from buildings on successive passes.

2. If there is a garage at the end of the driveway, plow to within several vehicle lengths of the garage and push the snow off the driveway.

3. Raise the blade and drive through the snow up to the garage. Drop the blade and "Back Drag" the snow 1-1/2 vehicle lengths back. Repeat as necessary.

4. Back the vehicle to garage door and plow forward toward street, removing the remaining snow.

Clearing Parking Lots

1. "Back Drag" areas in front of buildings and near walls then work away from buildings towards the outer edges of the lot.

2. Plow a single path down the center in the longest direction.

3. Angle plow toward the outside and make successive passes until the area is cleared and the snow is "Stacked" around the outer edges. If snow is too deep to clear in the above manner, clear main traffic lanes and stack snow at intermediate positions.

Introduction

Whenever service is necessary, your local dealer knows your plow best and is interested in your complete satisfaction. Return your snowplow to your local dealer for maintenance service or any other assistance you may require. If you are unable to do so, this trouble-shooting guide should help you determine the problem. However, before attempting the servicing of your plow, you should possess good mechanical abilities and a total understanding of the mechanism.

PLEASE: Before calling parts and service personnel be certain that:

1. You have read this guide carefully and are certain that all of the suggestions pertaining to your problem have been attempted.

2. You have the following available:

This information should be recorded on page 2 of this Owners Manual.

Troubleshooting Quick Reference

-General

Check vehicle electrical system for proper operation.

1. Check all wiring to be sure that battery terminals are clean and connections to battery, circuit breaker, solenoid, and all connectors on plow harness are clean and tight.

2. Check for external leakage at cylinders, hoses, and power unit.

3. Check the voltage at the coils which operate solenoid valves to be sure that the voltage at the coils is a minimum of 9½ volts DC.

Check oil level in hydraulic system reservoir

_{Down Pressure (DP) System} obstacle, allowing the cylinder to retract and allowing the blade to adjust its angle to relieve the force from the

This system operates only when both the ’DP’ switch and the ’Lower’ switch on the hand-held controller are actuated.

Actuating the ’DP’ switch 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’ is actuated and the hydraulic pump operates, hydraulic fluid is directed to the rod end of the lift cylinder, retracting the cylinder and forcing the plow down.

The pressure switch in 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 the pump.

The system is protected by a relief valve, which relieves excess pressure if 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, which will also lower the pressure. If the pressure becomes too low, the pressure switch will activate the motor and pump as mentioned above to return pressure to normal levels.

The down pressure system is overridden any time the plow control is placed in the ’Raise’ mode, but will resume when placed back in the ’Lower’ position.

Also, note that the ’E’ valve is deactivated anytime an angle function is activated, but returns to its previous condition as soon as the angle function is completed.

Angle Left or Right Mode of Operation

Actuating the ’Angle Right’ switch on the hand-held controller sends a signal to the control circuit board on the plow. This actuates the start solenoid and the coil for the ’A’ valve, allowing hydraulic fluid under pressure to flow through the ’A’ valve to the swing cylinder. At the same time, the hydraulic fluid passing through the ’A’ valve unseats a check valve in the circuit for the ’D’ valve, allowing hydraulic fluid to flow from the opposite swing cylinder through the ’D’ valve and back to the reservoir.

Actuating the ’Angle Left’ switch on the hand-held controller sends a signal to the control circuit board on the plow. This actuates the start solenoid and the coil for the ’D’ valve, allowing hydraulic fluid under pressure to flow to the swing cylinder. This fluid also unseats a check valve in the circuit for the ’A’ valve, allowing fluid to flow from the opposite swing cylinder through the ’A’ valve and back to the reservoir.

The angle circuits are protected by a crossover relief valve set to relieve pressure on the circuit a 2400 PSI. If the blade of the plow contacts an obstacle during plowing operations, the crossover relief valves will allow fluid to flow out of the swing cylinder on the side encountering the outside.

Circuit Breaker

A 150 amp circuit breaker is located near the battery in the primary 12V DC positive power circuit and is in place to protect the electrical system. A high amp draw condition will cause the breaker element in the circuit breaker to interrupt current flow to the plow. The circuit breaker will automatically reset after it cools down.
