Walkbehind Snowthrower

MAINTENANCE
BELT ADJUSTMENT
Traction Drive Belt
The traction drive belt has constant spring pressure and does not require
an adjustment. If the traction drive belt is slipping, replace the belt. See
authorized dealer.
Auger Drive Belt
If your snowthrower will not discharge snow, check the control cable
adjustment. If it is correct, then check the condition of the auger drive belt. If it
is damaged or loose, replace it (see authorized dealer).
Auger Drive Belt Adjustment:
1. Disconnect spark plug wire.
2. Remove screw (A, Figure 28) from belt cover (B). Remove belt cover.
3. Loosen nut on idler pulley (A, Figure 29) and move idler pulley
towards belt about 1/8 inch (3 mm).
WARNING: Do not over-tighten, as this may lift the
lever and cause the auger drive to be engaged without
depressing the auger control lever.
4. Tighten nut.
5. With the aid of an assistant, engage the auger drive clutch. Check
tension on belt which is opposite idler pulley (A, Figure 29). Belt
should deflect about 1/2 inch (12.5 mm) with moderate pressure.
You may have to move idler pulley more than once to obtain the
correct tension.
6. Reinstall belt cover (B, Figure 28). Tighten screw (A).
7. Attach the spark plug wire.
NOTE: Whenever belts are adjusted or replaced, the cables
will need to be adjusted (see “Check and Adjust the Cables”
section).
Check Auger Drive Belt:
1. Release the auger control lever. The auger must stop within 5
seconds.
2. If auger does not operate properly, stop engine and repeat “Auger
Drive Belt Adjustment.”
CHECK AND ADJUST THE CABLES
The cables are adjusted at the factory and no adjustment should be
necessary. If the cables have become stretched or are sagging adjustment
will be necessary.
Whenever belts are adjusted or replaced, the cables will need to be
adjusted.
Auger Control Cable Adjustment
WARNING: Do not over-tighten, as this may lift the
lever and cause the auger drive to be engaged without
depressing the auger control lever.
1. With the auger control lever released, the hook (A, Figure 31) should
barely touch the lever (B) without raising it. There can be a maximum
of 1/32" (0.8 mm) clearance.
2. To adjust, loosen the nut (C) by holding the adjusting flats (D) and
turning the nut. Then, turn the adjusting flats and hold the
adjustment screw (E). The adjustment screw is a phillips screw and
the head can be held or turned by inserting a screwdriver through the
spring (F).
3. Hold the adjusting flats and tighten the nut.
4. Start the engine and check the auger. The auger must not be engaged
unless the auger control lever is depressed.
5. With the engine running, fully depress the auger control lever. The
auger should engage and run normally.
6. Release the auger control lever. The auger must stop within
5 seconds.
7. If the auger does not operate properly, stop the engine and recheck
the auger control cable adjustment.
8. If the drive linkage is properly adjusted, the tension of the auger
drive belt may require an adjustment (see “Belt Adjustment” section).
BELT GUIDE ADJUSTMENT
1. Remove spark plug wire.
2. Have someone engage the auger drive. This will engage auger idler
pulley (A, Figure 30).
3. Measure the distance between the belt guide (B) and belt (C). The
distance should be about 1/8 inch (3 mm).
4. If adjustment is necessary, loosen belt guide mounting bolt. Move
belt guide to the correct position. Tighten mounting bolt.
5. Install belt cover.
6. Connect spark plug wire.
