Auger Control Test
IMPORTANT:
operating your snow thrower for the first time and at the start of each winter season.
Check the adjustment of the auger control as follows:
When the auger control is released and in the disengaged “up” position, the cable should have very little slack. It should NOT be tight.
Perform the following test before
WARNING: Do not over-tighten the cable.
Over-tightening may prevent the auger from disengaging and compromise the safety of the snow thrower.
In a well-ventilated area, start the snow thrower engine as instructed earlier in this section under the heading “Starting Engine”. Make sure the throttle is set in the FAST position.
While standing in the operator’s position (behind the snow thrower), engage the auger.
Allow the auger to remain engaged for approximately ten (10) seconds before releasing the auger control. Repeat this several times.
With the engine running in the FAST position and the auger control in the disengaged “up” position, walk to the front of the machine.
Confirm that the auger has completely stopped rotating and shows NO signs of motion.
IMPORTANT:
immediately return to the operator’s position and shut off the engine. Wait for ALL moving parts to stop before re-adjusting the auger control.
To readjust the control cable, loosen the hex jam nut on the auger control cable “Z” fitting.
Thread the ferrule without turning the cable onto the “Z” fitting until there is no slack in the cable. See Figure 8. Do not overtighten the cable. Hold the flats on the ferrule with pliers and tighten the jam nut against the ferrule.

Make certain to check for correct adjustment of the shift rod as instructed under “Drive Control and Shift Lever” on page 11, before operating the snow thrower.
Skid Shoe
The space between the shave plate and the ground can be adjusted by raising or lowering the skid shoes.
For close snow removal, as when using on a smooth concrete or asphalt driveway, place the skid shoes in the low position. Use the middle or high position when the area to be cleared is uneven. When operating on gravel, always put skid shoes in the high position. See Figure 13.
Adjust skid shoes as follows:
Loosen, but do not remove, the three hex nuts
which fasten the skid shoe to the auger housing.
Raise or lower the skid shoe to desired position.
Retighten the hex nuts loosened earlier.
Repeat on the other side of the snow thrower.
NOTE: Make certain the bottom surface of skid shoe is flat against the ground to avoid uneven wear.

Lube Cams Here
WARNING: If any adjustments need to be
made to the engine while the engine is running (e.g. carburetor), keep clear of all moving parts. Be careful of muffler, engine and other surrounding heated surfaces.
Drive / Auger Control Lock
The cams on the ends of the control rods which interlock the drive and auger controls must be lubricated at least once a season or every 25 hours of operation. The cams can be accessed beneath the handle panel. Use a multi-purpose automotive grease. See Figure 14.

Shear Pin
Plastic Bearing
To check the level of grease in the gear case, remove the vent plug. If your unit is equipped with a grease fitting, you may, if necessary, add grease using a grease gun and the grease fitting on the side of the gear case.
IMPORTANT:
damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.
Do not overfill the gear case, since

Auger Shaft
At least once a season, remove the shear pins from the auger shaft and spray lubricant inside the shaft. See Figure 15.
On certain models, grease fittings can be found at either end of the auger shaft. Lubricate with a grease gun once a season.
Auger Bearings
Every season lubricate the auger bearings and the bearings on the side of the frame with light oil. See Figure 15.
Drive and Shifting Mechanism
Lubricate at least once a season or after every 25 hours of operation. Remove the 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 the friction wheel rubber and aluminum drive plate. Refer to Figure 11.
There is a grease fitting on the top of the axle shaft which drives the rear track drive wheels on both sides of the unit. Grease these fittings every 25 hours or once a season.
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 automotive stores, or order part number 737-0170). Refer to Figure 11.
IMPORTANT:
friction wheel and aluminum drive plate.
Keep all grease and oil off of the rubber
Chute Directional Control
The worm gear on the chute directional control should be greased with multipurpose automotive grease.
SECTION 7: SERVICING YOUR SNOW THROWER
WARNING: Before servicing, repairing, or
inspecting, disengage all controls and stop engine. 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. Always wear safety glasses during operation or while performing any adjustments or repairs.
Augers
The augers are secured to the spiral shaft with shear pins and bow tie cotter pins. If you hit a hard foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Figure 17.
If the augers will not turn, check to see if the pins have sheared. Replacement shear pins and cotter pins have been provided with the snow thrower.
14
When replacing pins, spray an oil lubricant into shaft before inserting new pins.
IMPORTANT:
standard pins. Any damage to the auger gearbox or other components as a result of doing so will NOT be covered by your snow thrower’s warranty.
Shave Plate and Skid Shoes
The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary.
NEVER replace the auger shear pins with
