Using the Wheel Clutch Levers
Models 38637 and 38657 only
The wheel clutch levers allow you to momentarily disengage the drive to one or both wheels with the traction drive lever still engaged. This enables you to turn and maneuver the machine easily.
Note: Holding down the traction lever against the handle engages the traction drive to both wheels.
To turn the machine to the right, lift up on the right wheel clutch lever and squeeze it toward the handle
Operating the Speed Selector
The speed selector has 6 forward and 2 reverse gears.
To change speeds, release the traction lever and shift the
speed selector lever to the desired position (Figure 36).
The lever locks in a notch at each speed selection.
Figure 36
Figure 34
Note: This disengages the drive to the right wheel while the left wheel continues driving, and the machine turns to the right.
Note: Similarly, squeezing the left wheel clutch lever turns the machine to the left.
When you complete the turn, release the wheel clutch
lever, and the drive re-engages both wheels (Figure 35).
Operating the Auger/Impeller
Drive
1. To engage the auger/ impeller drive, squeeze the right hand (auger/ impeller) lever to the handgrip
Figure 37
Figure 35
Momentarily squeezing and releasing the left or right wheel clutch lever also allows for steering adjustments to keep the machine going in a straight line, especially in deep snow.
Squeezing both wheel clutch levers simultaneously disengages the drive to both wheels. This enables you to manually move the machine backward without stopping to shift it into a reverse gear. It also allows you to maneuver and transport the machine more easily when the engine is not running.
2. To stop the auger and impeller, release the right hand lever.
Important: When you engage both the auger/impeller lever and the traction lever, the traction lever locks the auger/impeller lever down, freeing your right hand. To release both levers, simply release the left hand (traction) lever.
3. If the auger and impeller continue to rotate when you release the auger/impeller lever, do not operate the machine. Check the auger/impeller cable (refer to Checking and Adjusting the Auger/Impeller
Cable) and adjust it if necessary. Otherwise, take the machine to an Authorized Dealer for service.

Unclogging the Discharge
Chute
If the auger/impeller is running but there is no snow coming out of the discharge chute, the discharge chute may be clogged.
• To unclog the discharge chute, stay in the operating position and release the left hand (traction) lever.
While running the auger/impeller, push down on the handles to raise the front of the machine a few inches (centimeters) off the pavement. Then lift the handles quickly to bump the front of the machine on the pavement. Repeat if necessary until a stream of snow comes out the discharge chute.
• If you cannot unclog the discharge chute by bumping the front of the machine, stop the engine, wait for all moving parts to stop, and use a stick; never use your hand.
Important: Unclogging the discharge chute by bumping the front of the machine on the
18
pavement may cause the skids to move. Adjust the skids and tighten the skid bolts securely.
Preventing Freeze-up
• 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.
• After using the machine, let the engine run for a few minutes to prevent moving parts from freezing.
Engage the auger/impeller to clear any remaining snow from inside the housing. Rotate the Quick
Stick to prevent it from freezing. Stop the engine, wait for all moving parts to stop, and remove all ice and snow from the machine.
• With the engine off, pull the recoil starter handle several times and push the electric-starter button once (all models except 38597) to prevent the recoil and electric starters from freezing up.
Operating Tips
DANGER
When the machine is in operation, the impeller and auger can rotate and cut off or injure hands and feet.
• Before adjusting, cleaning, inspecting, troubleshooting, or repairing the machine, stop the engine and wait for all moving parts to stop.
Disconnect the wire from the spark plug and keep it away from the plug to prevent someone from accidentally starting the engine.
• Remove an obstruction from the discharge chute; refer to Unclogging the Discharge Chute.
If necessary, use a stick, not your hands, to remove an obstruction from the discharge chute.
• Stay behind the handles and away from the discharge opening while operating the machine.
• Keep face, hands, feet, and any other part of your body or clothing away from concealed, moving, or rotating parts.
WARNING
The rotor blades can throw stones, toys, and other foreign objects and cause serious personal injury to the operator or to bystanders.
• Keep the area to be cleared free of all objects that the rotor blades could pick up and throw.
• Keep all children and pets away from the area of operation.
• Always set the throttle to the Fast position when throwing snow.
• If the engine slows down under a load or the wheels slip, shift the machine into a lower gear.
• If the front of the machine rides up, shift the machine into a lower gear. If the front continues to ride up, lift up on the handles.
• The pivoting scraper on the machine is not recommended for use on gravel surfaces.
But if you must use the machine on a gravel surface, adjust the skids further down to prevent the pivoting scraper from picking up rocks.
