AUGER DRIVE ADJUSTMENT
1. With the drive lever released, the hook (B, Figure
20) should barely touch the lever (C) without
raising it. There can be a maximum 1/32”
clearance as shown.
2. To adjust, loosen nut (D) by holding the adjusting
flats (A) and turning nut (D). Turn adjustment flats
and hold screw. The adjustment screw (E) is a
phillips screw and the head can be held or turned
by inserting a screwdriver through the spring (F).
3. Hold adjusting flats (A) and tighten nut (D).
4. Start unit and check auger. Auger must not be
engaged unless auger control is depressed.
5. With engine running, fully depress auger control,
the auger should engage and run normally.
6. Release auger control. Auger must stop within 5
seconds.
7. If auger does not operate properly, stop engine
and recheck drive linkage adjustments.
8. If auger linkage is properly adjusted, auger drive
belt tension may require adjustment. See adjusting
the auger belt in this section of the manual
WARNING
Do not over-tighten, as this may cause traction
drive to engage without depressing the traction
drive control (arm must remain in up position).
Verify that the cables are not over-tightened:
With speed selector in position 1 and traction
drive control fully released, push snowthrower
forward. The unit should move forward freely.
If unit does not move forward freely, the cable
has been over-tightened. To remedy, loosen
tension on clutch cable slightly, and recheck.
WARNING
Do not over-tighten, as this may lift the lever
and cause auger drive to be engaged without
depressing the Auger Control.
TRACTION DRIVE ADJUSTMENT
Initial Adjustment
1. With the drive lever released there should be slack
in the cable when moved slightly from side to side.
2. To adjust tension on the cable slide the cable boot
(A, Figure 21) off the cable adjustment bracket (D).
3. Move the “Z” hook (C) from the cable adjustment
bracket (D) to a different adjustment hole. The
cable should have slack. The cable should have
no tension or load.
Note: If the cable is too slack the unit will not drive. If
the cable is too tight the drive will be engaged without
pushing the handle down.
4. Slide the cable boot (A) over the cable adjustment
bracket.
