2.Push starter button to start engine.

3.Once the engine starts, immediately release starter button.

4.As the engine warms, slowly rotate the choke control

to the OFF position

 

 

. If the engine falters,

quickly rotate the choke

 

control back to FULL and

then slowly into the OFF position again.

5.When disconnecting the extension cord, always unplug the end at the three-prong wall outlet before unplugging the opposite end from the snow thrower.

Recoil Starter

1.Grasp the recoil starter handle and slowly pull the rope out. At the point where it becomes slightly harder to pull the rope, slowly allow the rope to recoil.

2.Pull the starter handle with a firm, rapid stroke. Do not release the handle and allow it to snap back. Keep a firm hold on the starter handle and allow it to slowly recoil.

3.As the engine warms, slowly rotate the choke control to the OFF position. If the engine falters, quickly rotate the choke control back to the FULL position and then slowly into the OFF position again.

NOTE: Allow the engine to warm up for a few minutes after starting. The engine will not develop full power until it reaches operating temperatures.

StoppingThe Engine

Run engine for a few minutes before stopping to help dry off any moisture on the engine.

Push the rocker switch to the “OFF” position.

Pull out the safety key.

Close fuel shut-off valve (If equipped).

Wipe all snow and moisture from the area around the engine as well as the area in and around the drive control and auger control. Also, engage and release both controls several times.

To Engage Drive

1.With the engine running near top speed, move shift lever to one of six FORWARD positions or two

REVERSE positions. Select a speed appropriate for the snow conditions that exist.

2.Squeeze drive control against the right handle and the snow thrower will move. Release it and the drive motion will stop.

To Engage Augers

1.To engage augers and start snow throwing, squeeze the left hand auger control against the left handle. Release to stop augers.

2.While the auger control is engaged, squeeze the drive control to move, release to stop. Do not shift speeds while the drive is engaged.

NOTE: The drive control lever also locks auger control so you can turn the chute control without interrupting the snow throwing process.

3.Release the auger control; the interlock mechanism should keep the auger control engaged until the drive control is released.

4.Release the drive control to stop both the augers and the wheel drive. To stop the auger, both levers must be released.

Never attempt to make any adjustments while the engine is running, except where specified in operator’s manual.

Run the engine completely dry of gasoline before tipping snowthrower.

Figure 5-1

Shift Rod

If the full range of speeds (forward and reverse) cannot be achieved, refer to Figure 5-1 and adjust the shift rod as follows:

1.Looking underneath the handle panel, note which of the three holes in the shift lever the ferrule is inserted into. Also note the direction of insertion. Then remove the internal cotter pin and flat washer from the ferrule and withdraw the ferrule from the shift lever. See Figure 5-1.

2.Place shift lever in sixth (6) position or fastest forward speed.

3.Push shift rod and shift arm assembly down sharply, as far as it will go to put the drive into the fastest forward position.

4.As necessary, rotate the ferrule up or down the shift rod until the ferrule lines up with the hole from which it was earlier removed. See Figure 5-1.

5.From the direction noted earlier, insert the ferrule into the proper hole.

6.Reinstall the washer and the internal cotter pin.

Drive Control

WARNING: Run the engine completely dry of gasoline before tipping snowthrower.

Refer to the Final Adjustment section of the Set-Up instructions to adjust the drive control. To further check the adjustment, proceed as follows:

1.Tip the snow thrower forward, allowing it to rest on the auger housing.

2.Remove the frame cover underneath the snow thrower by removing the self-tapping screws. See Figure 5-2.

3.With the wheel drive control released, check if there is clearance between friction wheel and drive plate in all positions of the shift lever. See Figure 5-3.

Skid Shoes

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 5-4.

Adjust skid shoes as follows:

1.Loosen, but do not remove, the hex flange locknuts which fasten the skid shoe to the auger housing.

2.Raise or lower the skid shoe to desired position.

3.Retighten the hex nuts loosened earlier.

NOTE: Make certain the bottom surface of skid shoe is flat against the ground to avoid uneven wear.

4. Repeat on the other side of the snow thrower.

Auger Control

Refer to instructions on page 9 to adjust the auger control. Make certain to check for correct adjustment as instructed before operating the snow thrower.

Chute Assembly

The distance snow is thrown can be adjusted by adjusting the angle of the chute assembly. Refer to page 9 for instructions.

The remote chute control cables have been pre-adjusted at the factory. Move the remote chute lever on the control panel back and forward to adjust angle of the chute assembly.

Chute Bracket Adjustment

If the spiral at the bottom of the chute directional control is not fully engaging with the chute assembly, the chute bracket can be adjusted. To do so:

1.Loosen the two nuts which secure the chute bracket and reposition it slightly. See Figure 5-5.

2.Retighten the nuts.
