Safety Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with the safety instructions in the traction unit operator’s manual and always pay attention to the safety alert symbol, which means CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death. POTENTIAL HAZARD • Stones and other foreign objects may be picked up and thrown by the rotor blades.
Safety • Never operate the snowthrower without proper guards, plates, or other safety protective devices in place. • Never operate the snow thrower near glass enclosures, automobiles, window wells, drop-offs, and the like without proper adjustment of the snow discharge angle. Keep children and pets away. Operation • Do not overload the machine capacity by attempting to clear snow at too fast a rate. • Do not put hands or feet near or under rotating parts.
Safety • The rotating auger/impeller or rotor blades can cut off or injure fingers or hands. Stay in the operator’s position and away from the discharge opening while operating the snowthrower. Keep your face hands, feet, and any other part of your body or clothing away from concealed, moving, or rotating parts. • Before adjusting, cleaning, repairing, and inspecting the snowthrower, and before unclogging the discharge chute, stop the engine, remove the key, and wait for all moving parts to stop.
Safety Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Operation Operating the Power Take Off (PTO) POTENTIAL HAZARD • When snowthrower is attached to the tractor, without additional weight, the tractor may become unstable. WHAT CAN HAPPEN • Loss of traction and stability may cause loss of tractor control. HOW TO AVOID THE HAZARD • NEVER operate tractor, equipped with snowthrower, unless 100lb rear wheel weights are installed. POTENTIAL HAZARD • Rotating auger can cut off fingers, hands or other body parts and throw objects.
Operation Attachment Lift Lever Attachment Power Lift The attachment lift lever (Fig. 30) is used to manually raise and lower attachments. The attachment power lift (Fig. 31) is used to raise and lower attachments. Raising Attachments Raising Attachments 1. Depress the clutch and/or brake pedal(s) to stop the machine. 1. Start the engine, refer to; Starting and Stopping the Engine, in the Tractor Operator’s Manual. 2. Pull attachment lift lever rearward until latch locks.
Operation Adjusting Dial-A-Height The Dial-A-Height control (Fig. 30) is used to limit the downward travel of the attachment. The Dial-A-Height knob is rotated to change the location of this stop, up or down. 1. Raise the attachment lift: Refer to Raising Attachments. In the raised position the Dial-A-Height knob (Fig. 30) can be rotated to change the stop location. Turn clockwise to raise and counterclockwise to lower the height of the attachment. 2.
Operation Tips for Throwing Snow Remove snow as soon as possible after it falls. This produces best snow removal results. Adjust skids to match the type of surface being cleaned; refer to Adjusting Skids. The snowthrower is designed to clean snow down to the contact surface, but there are times when the front of the snowthrower may tend to ride up. If this happens, reduce forward speed. Discharge snow downwind whenever possible, and overlap each pass to ensure complete snow removal.

Maintenance Greasing and Lubrication Service Interval/Specification Grease and oil the machine after every 25 operating hours or once a year, whichever occurs first. Grease Type: General-purpose grease. Oil Type: SAE 10W or 10W30. 1280 Figure 33 How to Grease 1. Disengage the power take off (PTO), set the parking brake, and turn the ignition key to “OFF” to stop the engine. Remove the key. m–2583 Check Gear Box Lubricant 1.
Maintenance Adjusting Skids Replacing Scraper Blade The distance between the scraper blade and the ground is controlled by skids on each side of the housing. The height can be adjusted so the scraper blade will not catch on uneven surfaces The scraper blade contacts the ground preventing damage to the snowthrower housing. Periodically inspect the scraper blade for wear. When scraper becomes worn, before working surface contacts the housing, replace the scraper blade. 1.
Maintenance Adjusting Drive Chain Tension Replace Drive Belt Check the drive chain tension after every 25 operating hours or once a year, whichever occurs first. Adjustment as necessary to maintain proper tension. 1. Remove belt covers from tractor and snowthrower (Fig. 38), 1 1. Disengage the power take off (PTO), set the parking brake, and turn the ignition key to “OFF” to stop the engine. Remove the key. 2. Remove chain cover (Fig. 37). 3.
Maintenance 6. Remove rear idler and replace belt (Fig. 40). Install rear idler. 7. Install belt covers on tractor and snowthrower (Fig. 38), 1 2 3 26 1. Before long term storage wash the machine with mild detergent and water to remove dirt and grime from the entire machine. 2. Check the condition of the scraper blade; refer to Reversing Scraper Blade, page 24. 3. Check the condition of the drive belt and chain. 4. Grease and oil the snowthrower; refer to Greasing and Lubrication, page 23. 5.
Troubleshooting PROBLEM Snow does not discharge g Auger does not rotate. Abnormal vibration. POSSIBLE CAUSES CORRECTIVE ACTION 1. Discharge chute plugged. 1. Clean chute with a stick. 2.
