Skid Shoe Adjustment The space between the shave plate and the ground can be adjusted by raising or lowering the skid shoes. Refer to Skid Shoe Adjustment in the Assembly Section. Auger Control Adjustment Refer to the information found under Final Adjustments in the Assembly Section to adjust the auger control. Traction Control Adjustment Refer to the information found under Final Adjustments in the Assembly Section to adjust the traction control. If you are uncertain that you have reached the correct adjustment, proceed as follows: WARNING: Drain the gasoline out of your snow thrower’s engine or place a piece of plastic film under the gas cap to avoid spillage BEFORE beginning to perform this adjustment. • Tip the snow thrower forward, allowing it to rest on the auger housing. • Remove the frame cover underneath the snow thrower by removing six self-tapping screws. With the traction control released, there must be clearance between the friction wheel and the drive plate in all positions of the shift lever. With the traction control engaged, the friction wheel must contact the drive plate. See Figure 9. If adjustment is necessary: • Loosen the jam nut on the traction drive cable and thread the cable in or out as necessary. • Retighten the jam nut to secure the cable when correct adjustment is reached. • Reassemble the frame cover. NOTE: If you placed plastic film under the gas cap, be certain to remove it before operating the snow thrower. Spiral Support Hex Nuts Bracket 11 Figure 9 Shift Rod Adjustment To adjust the shift rod, proceed as follows: • Remove the hairpin clip and slide the connector up to separate the upper shift rod from the lower shift rod. See Figure 10. Figure 10 • Place shift lever in sixth (6) position. • Rotate the shift arm counterclockwise (from the operator’s position) as far as it will go. • Thread the upper shift rod downward until the elbow on its lower end aligns with the hole found in the lower shift rod. • Reconnect the upper shift rod to the lower shift rod by reinserting the hairpin clip removed earlier and sliding the connector back down into place. IMPORTANT: Make certain to check for correct adjustment of the shift rod as instructed under Final Adjustments in the Assembly Section, before operating the snow thrower. Drive Wheels The wheels may be adjusted for two different methods of operation. The adjustment is made by placing the click pins in one of two different holes on the right side of the unit. See Figure 11. Figure 11 One Wheel Driving: Insert the click pin only through the outside hole of the axle (NOT the rim) on the right side of the snow thrower. This position gives power drive to the left wheel only, making the unit easier to maneuver. Both Wheels Driving: Insert the click pin through the hole in the hub of the rim and the INSIDE hole on the snow thrower’s right axle. This position is good for heavy snow as there is power drive in both wheels. IMPORTANT: NEVER operate the snow thrower with the click pin inserted through both the RIM and the OUTSIDE HOLE in the axle. Doing so can result in serious damage to the drive system.

Wait until all moving parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting. Lubrication Wheels • Oil or spray lubricant into plastic wheel bearings inside the wheel hubs at least once a season. Remove wheels, clean and coat axles with a multipurpose automotive grease. See Figure 12. Figure 12 Auger Shaft • At least once a season, remove the shear bolts on the auger shaft. Oil or spray lubricant inside and on the plastic bearings on the shaft. See Figure 13. Figure 13 Gear Shaft Lubricate the gear shaft with 6-n-1 grease at least once a season or after every 25 hours of operation (available at auto parts stores or order part number 737-0170). Refer to Figure 9. Gear Case The gear case is equipped with a grease fitting on the left housing and should be lubricated with Shell Alvania grease EPR00, part number 737-0168 every 25 hours. See Figure 14. Figure 14 IMPORTANT: Do not overfill the gear case. Damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure. Drive and Shifting Mechanism At least once a season or after every 25 hours of operation, remove rear cover. Lubricate any chains, sprockets, gears, bearings, shafts, and shifting mechanism at least once a season. Use engine oil or a spray lubricant. Avoid getting oil on rubber friction wheel and aluminum drive plate. Refer to Figure 9.
