Controls Operation Use the switches from the Low Flow Hydraulic Kit (Figure 21) and the height-of-cut lever to operate the snowthrower. Operating the Snowthrower Important: Raise the snowthrower when transporting it. Low Flow Hydraulic Kit Switches • Move the left switch up or down to raise or lower the snowthrower. 1. Start the machine. 2. Move the throttle lever midway between the FAST and SLOW positions.
Adjusting the Drift Breakers Clearing a Clogged Snowthrower WARNING If the auger/impeller is running but there is no snow coming out of the discharge chute, the discharge chute may be clogged. Never use your hands to clear a clogged discharge chute. This could result in personal injury. 1. Park the machine on a level surface, disengage the PTO, and engage the parking brake. 2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3.
Loading the Machine Selecting a Trailer WARNING WARNING Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death (Figure 24). Loading a machine onto a trailer or truck increases the possibility of tip-over and could cause serious injury or death. • Use only a full-width ramp; do not use individual ramps for each side of the machine. • Use extreme caution when operating a machine on a ramp.
Preventing Freeze-up after Use • In snowy and cold conditions, some controls and moving parts may freeze. Do not use excessive force when trying to operate frozen controls. If you have difficulty operating any control or part, start the engine and let it run for a few minutes. Thaw frozen parts before operating the machine. • After using the machine, let the engine run for a few minutes to prevent moving parts from freezing.
Maintenance Adjusting the Skids Service Interval: Every 50 hours—Check the skids. CAUTION Check the skids to ensure that the auger does not contact the paved or gravel surface. Adjust the skids as needed to compensate for wear. If you leave the key in the switch, someone could accidently start the engine and seriously injure you or other bystanders. Shut off the engine and remove the key from the switch before you perform any maintenance. Maintenance Safety 1.
