PAGE 17
Operating the Traction Drive Using the Wheel Clutch Levers Models 38637 and 38657 only CAUTION 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. If the traction drive is not properly adjusted, the machine may move in the direction opposite of what you intended, causing injury and/or property damage.
PAGE 18
Operating the Speed Selector WARNING If the auger and impeller continue to rotate when you release the auger/impeller lever, you could seriously injure yourself or others. 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 38). The lever locks in a notch at each speed selection. Do not operate the machine. Take it to an Authorized Service Dealer for service.

Preventing Freeze-up • If the chute does not move, refer to Adjusting the Discharge Chute Latch. • If the chute does not turn as far to the left as it does to the right, ensure that the cable is routed to the inside of the handles. Refer to Installing the Upper Handle. • If the chute does not lock into place when you release the trigger cap, refer to Adjusting the Discharge Chute Latch. • In snowy and cold conditions, some controls and moving parts may freeze.
PAGE 20
• If the engine slows down under a load or the wheels slip, shift the machine into a lower gear. if you must use the machine on a gravel surface, adjust the skids further down to prevent the pivoting scraper from picking up rocks. • 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.
PAGE 21
Preparing for Maintenance 1. Move the machine to a level surface. 2. Stop the engine and wait for all moving parts to stop. 3. Disconnect the spark plug wire. Refer to Replacing the Spark Plug. Figure 44 Checking the Engine Oil Level 1. 1/2 inch (1.3 cm) Service Interval: Before each use or daily—Check the engine oil level and add oil if necessary. 3. Support the side plates so that they are at least 1/2 inch (1.3 cm) above a level surface. 1.
PAGE 22
Checking and Adjusting the Traction Cable Service Interval: After the first 2 hours—Inspect the traction cable and adjust it if necessary. Yearly—Inspect the traction cable and adjust or replace it if necessary. Figure 45 1. Skid If the machine does not drive in the forward or reverse speeds or it drives when you release the traction lever, adjust the traction cable. 4.
PAGE 23
Checking the Auger Gearbox Oil Level Service Interval: Yearly—Check the auger gearbox oil and add oil if necessary. 1. Move the machine to a level surface. 2. Clean the area around the pipe plug (Figure 49). Figure 50 1. Using SAE 30 at outdoor temperatures below 40°F (4°C) will result in hard starting. Figure 49 2. Using 10W-30 at outdoor temperatures above 80°F (27°C) may result in increased oil consumption; therefore, check the oil level more frequently in these circumstances.
PAGE 24
Adjusting the Discharge Chute Latch Note: The latch is spring loaded and will naturally move into the teeth of the gear (Figure 54). 4. Remove any slack in the cable by pulling the cable conduit rearward. If the discharge chute does not lock into the desired position or does not unlock so that you can move it to another position, adjust the discharge chute latch. 1. Remove the fastener on the gear cover (Figure 52), lift the front of the cover up, and slide it back and out of the way. 5.

Storage WARNING • Gasoline vapors can explode. • Do not store gasoline more than 30 days. • Do not store the machine in an enclosure near an open flame. • Allow the engine to cool before storing it. Figure 57 4. Insert a new bulb into the back of the headlight (Figure 58). Preparing the Machine for Storage 1. On the last refueling of the year, add fuel stabilizer to fresh fuel as directed by the engine manufacturer. 2.
PAGE 26
17. Tighten all loose screws, bolts, and locknuts. Repair or replace any damaged parts. 18. Cover the machine and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure. Removing the Machine from Storage 1. Remove the spark plug and spin the engine rapidly using the starter to blow the excess oil from the cylinder. 2. Install the spark plug by hand and then torque it to 15 ft-lb (20.4 N-m). 3. Connect the spark plug wire. 4.
