Remove the lower two plastic wing knobs, cupped washers and carriage bolt (eyebott on the left side) from the lower handle. See Figure 3. WARNING: Over-tightening the cable may prohibit the auger and drive from disengaging and compromise the safety of the snow thrower. Do NOT overtighten the cable. Once properly adjusted, tighten the jam nut against the coupling end of the cable to lock it in position. Refer to AugerControlTeston page 13 prior to operating your snow thrower.

AttachingClutchGrips(HardwareGroupB) Slide spacer on each end of the clutch grip and place the clutch grip in position on the each respective handle. Clutch grips must sit on top of the handles. See Figure 6. ,_Hex -. Lock Nut AttachingSpeedSelectorPlateAnd ShiftLever(HardwareGroupD) Assemble the speed selector plate to the outside of the handles. Secure using two self-tapping screws on each side. See Figure 8.

"Z" Fitting Chute Assembly sure cable is straight ck Nut Figure 9 Thread the jam nuts all the way up each of the Z fittings, toward the handle panel. See Figure 9. Make certain all cables are in the grooves of the cable roller guides in the lower rear of the unit, one on each side. Refer to Figure 5. Thread the coupling end of the cable onto the threaded portion of the Z fitting until the rubber bumper (located on the underside of the clutch lever) only lightly contacts the upper handle.
PAGE 10
Thread one hex nut onto the eyebolt on the chute directional control assembly until there is at least two inches of threads showing between the nut and the eyebolt head. See Figure 12. Place the eyebolt into the hole located half way up the left handle and secure with cupped washer and hex nut making sure that the cupped side of the washer is against the handle. Adjust the chute directional control bracket so that the spiral on the chute directional control fully engages the teeth on the chute assembly.
PAGE 11
SafetyIgnitionKey WARNING: Never use your hand to clear a clogged discharged chute. Shut off engine and remain behind handles until all moving parts have stopped before unclogging. The safety ignition key must be fully inserted in the switch before the unit will start. Remove the ignition key when the snow thrower is not in use. See Figure 14. IMPORTANT: Do NOT "turn" the ignition key in an attempt to start the engine. Doing so may cause it to break.

GasAndOilFill-up Push primer button two or three times for cold engine start, making sure to cover vent hole in primer button when pushing. DO NOT use primer to restart a warm engine after a short shutdown. Push starter button to start engine. When engine starts, release starter button and move choke gradually to OFF. If engine falters, move choke immediately to FULL and then gradually to OFF.
PAGE 13
Disconnect the spark plug wire from the spark plug to prevent accidental starting while equipment is unattended. To readjust the control cable, loosen the hex jam nut on the auger control cable "Z" fitting. Rotate the coupling end of the cable counterclockwise to provide more slack. Retighten the hex jam nut. See Figure 15. Repeat Auger Control Test to verify proper adjustment has been achieved. NOTE: Do not lose ignition key. Keep it in a safe place. Engine will not start without ignition key.

Frame Cover AugerControl Refer to Auger Control Test in the Operating Section to adjust the auger control. SkidShoes The space between the shave plate and the ground can be adjusted. See Figure 19. For close snow removal on a smooth surface, raise skid shoes higher on the auger housing.
PAGE 16
DriveWheels 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. 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 20.
PAGE 17
Gear Case The worm gear case has been filled with grease at the factory. If disassembled for any reason, lubricate with 2 ounces of shell grease, part number 737-0168. C.oln 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 Remove rear cover. Oil any chains, sprockets, gears, bearings, shafts, and shifting mechanism at least once a season. Use engine oil or a spray lubricant.
