Assembly Install Rear Weight Box 6 5 2 3 POTENTIAL HAZARD • When snowthrower is attached to the traction unit, without additional weight, the traction unit becomes unstable. WHAT CAN HAPPEN • Loss of traction and stability may cause loss of control. HOW TO AVOID THE HAZARD • To ensure proper handling and safety characteristics, rear weight box filled with sand or gravel or (4) rear weights must be attached to rear of traction unit.
Assembly Install Valve Assembly POTENTIAL HAZARD • Hydraulic fluid escaping under high pressure can penetrate skin. 3.

Operation Operating the Power Take Off (PTO) The power take off (PTO) switch engages and disengages power to the electric clutch. Implement Lift Lever The implement lift lever (Fig. 15) is used to raise and lower various attachments. Raising Attachments Engaging the PTO 1. Release the parking brake. 2. Release pressure on the traction pedal to stop movement (Fig. 14). 3. To engage lift cover and move the PTO switch to the “ON” position (Fig. 14). 1.
Operation Adjust Flow Control Valve 1. Loosen set screw and gently turn adjustment knob all the way to the right to close, then open 1–2 turns (Fig. 16). 2. After snowthrower is installed, start engine and cycle hydraulic lift several times to remove air from the lines and warm fluid. 3. Cycle raising and lowering snowthrower several times. Rotate knob on flow control valve so a decent rate of approximately 3 seconds is obtained (Fig. 16). Note: 4.

WHAT CAN HAPPEN • Accidental starting of the engine could seriously injure you or other bystanders.
Maintenance Check Auger Gear Box Oil Grease and Lubrication Check level of oil in auger gear box every 50 hours. Changing Gear Case Oil Change gear case oil initially after 5 hours of operation. Thereafter change oil after every 50 hours of operation. 1. With snowthrower lowered and on a level surface, remove pipe plug from auger gear box (Fig. 18) by placing the open end of a 3/8” drive socket extension over plug and using a 3/8” open end wrench on the square end of the extension. 1.
Maintenance Grease Flexible Shaft and Worm Gear Adjusting Skids Grease flexible shaft every 50 hours. 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 1. Grease flexible shaft (Fig. 19) with No. 2 lithium base grease until grease appears at each end of flexible shaft. 2. Check operation of chute crank and discharge chute.
Maintenance Replacing Scraper Blade Storage 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. Before long term storage wash the snowthrower with mild detergent and water to remove dirt and grime from the entire attachment. 2. Check the condition of the scraper blade; refer to Replacing Scraper Blade, page 17. 3.
