5. Connecting the Wire to the Headlight 1 Cable tie Procedure 1. Insert the wire connector on the loose end of the wire straight into the back of the headlight until it is securely in place (Figure 17). Figure 18 1. Using SAE 30 at outdoor temperatures below 40°F (4°C) will result in hard starting. 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. Engine Oil Capacities Figure 17 1.
PAGE 12
Note: Do not spill oil around the oil fill tube; oil could leak onto traction parts and cause the traction to slip. The snowthrower should move rearward. If the snowthrower does not move or moves forward, complete the following: A. Release the traction lever and stop the engine. 7. Checking the Tire Pressure B. Disconnect the trunnion from the speed selector lever (Figure 11). Procedure C. Turn the trunnion downward (clockwise) on the speed control rod (Figure 11).

Important: To prevent damaging the electric starter, run it in short cycles (5 seconds maximum, then wait one minute before trying to start it again). If the engine still does not start, take the snowthrower to an Authorized Service Dealer for service (all models except 38597). 8. Disconnect the power cord from the power outlet first and then from the snowthrower (all models except 38597). 9. Allow the engine to warm up for several minutes, move the choke toward the Run position.
PAGE 16
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 snowthrower easily. Note: Holding down the traction lever against the handle engages the traction drive to both wheels. To turn the snowthrower to the right, lift up on the right wheel clutch lever and squeeze it toward the handle (Figure 34). Figure 32 5.
PAGE 17
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. If the auger and impeller continue to rotate when you release the auger/impeller lever, you could seriously injure yourself or others. Do not operate the snowthrower. Take it to an Authorized Service Dealer for service.
PAGE 18
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 19
• If the engine slows down under a load or the wheels slip, shift the snowthrower into a lower gear. The rotor blades can throw stones, toys, and other foreign objects and cause serious personal injury to the operator or to bystanders. • If the front of the snowthrower rides up, shift the snowthrower into a lower gear. If the front continues to ride up, lift up on the handles. • Keep the area to be cleared free of all objects that the rotor blades could pick up and throw.

Preparing for Maintenance 1. Move the snowthrower 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 42 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 21
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 43 1. Skid If the snowthrower does not drive in the forward or reverse speeds or it drives when you release the traction lever, adjust the traction cable. 4.
PAGE 22
Checking and Adjusting the Auger/Impeller Cable Service Interval: After the first 2 hours—Inspect the auger/impeller cable and adjust it if necessary. Yearly—Inspect the auger/impeller cable and adjust or replace it if necessary. 1. Remove the 2 screws from the right side of the belt cover as shown. 2. Lift up the right side of the belt cover (Figure 47). Figure 49 1. Jam nut 2. Turnbuckle 6. Loosen or tighten the turnbuckle that adjusts the tension on the cable (Figure 49). 7.

5. If the oil level is low, add GL-5 or GL-6, SAE 85-95 EP transmission oil to the gearbox until the point of overflow. Engine Oil Capacities (cont'd.) Note: Do not use synthetic oil. Model Engine Oil Capacity 38597 18 to 20 oz. (0.53 to 0.59 l) 38629 6. Install the pipe plug in the gearbox. 38637 38639 Changing the Engine Oil 38657 Service Interval: After the first 5 hours—Change the engine oil. 26 to 28 oz. (0.77 to 0.83 l) 1. Clean the area around the oil drain cap (Figure 52).
PAGE 24
Lubricating the Hex Shaft Replacing the Spark Plug Service Interval: Yearly Service Interval: Every 100 hours—Replace the spark plug. Lightly lubricate the hex shaft yearly with automotive engine oil (Figure 53). Use a Champion QC12YC or equivalent spark plug. Note: To access the spark plug, you must first remove the upper snow hood (Figure 55). Figure 53 1. Hex shaft 2. Aluminum friction plate 3.

10. Remove the ignition key. 11. Disconnect the spark plug wire. 12. Remove the spark plug, add 1 oz. (30 ml) of oil through the spark plug hole, and pull the starter rope slowly several times to distribute oil throughout the cylinder to prevent cylinder corrosion during the off-season. 13. Loosely install the spark plug. 14. Dispose of any unused fuel properly. Recycle it according to local codes, or use it in your automobile. Note: Do not store stabilized fuel for more than 90 days. Figure 66 15.
