Large Frame Snowthrowers
TP 300-4458-00-LW-SN 07/200714
WARNING
Do not over-tighten, as this may cause traction
drive to engage without depressing the traction
drive control (arm must remain in down 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.
1. Check that the auger cable (A, Figure 3) is on top of
cable button (B) as shown in Figure 3.
2. With the drive lever released, the hook (B, Figure 4)
should barely touch the lever (C) without raising it.
There can be a maximum 1/32” clearance as shown.
3. 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).
4. Hold adjusting flats (A) and tighten nut (D).
5. Start unit and check auger. Auger must not be
engaged unless auger control is depressed.
6. With engine running, fully depress auger control, the
auger should engage and run normally.
7. Release auger control. Auger must stop within 5
seconds.
8. If auger does not operate properly, stop engine and
recheck drive linkage adjustments.
9. If auger linkage is properly adjusted, auger drive belt
tension may require adjustment. See adjusting the
auger belt in this section of the manual
