rized dealer.
Traction Drive Belt Adjustment
Speed Control Rod Adjustment
If the Easy Turn cable has stretched, the gears will not dis-
engage when the control lever is activated. Adjust the cable
using the following procedure.
1. Turn the engine off and remove the key.
2. Loosen the jam nut (A, Figure 15).
3. Turn the adjustment nut (B) to lengthen or shorten the
cable. The cable should be tightened until all slack is
removed from the lever. However, it must not engage the
Easy Turn without depressing the control lever.
4. Tighten the jam nut (A).
Easy Turn™ Cable Adjustment
The cables are adjusted at the factory and no adjustment
should be necessary. However, if the cables have become
stretched or are sagging, adjustment will be necessary.
Please see your dealer for this adjustment.
Traction Cable Inspection
1. With the auger control lever released, the hook (A, Figure
16) 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. To ensure that the auger does not engage unless the
control is fully depressed, please perform the Safety
System Tests . The auger must stop within 5 seconds
of the control being released.
Auger Cable Adjustment
WARNING
Amputation hazard
Over-tightening the auger cable may cause the auger drive
to engage without depressing the auger drive control.
Follow the adjustment procedure to ensure the cable is not
over-tightened.
Augers are secured to the auger shaft with special hardware
designed to break if an object becomes lodged in the auger
housing.
Please refer to the Illustrated Parts List to determine if your
unit requires a shear pin, shear bolt, or shear bolt and spacer
combination.
Use only factory authorized replacement parts, or like, parts
when making repairs.

You Have
WARNING
Amputation hazard
The discharge chute contains a rotating impeller to throw
snow. Fingers can quickly become caught and traumatic
amputation or severe laceration will result. Hand contact
with the rotating impeller inside the discharge chute is the
most common cause of injury associated with snowthrow-
ers.
Turn the engine OFF, wait for all moving parts to stop, and
remove the engine key before performing any maintenance
or repairs.
Shear Pin Replacement
1. Turn off the engine and wait for all moving parts to stop.
2. Remove the existing shear pin.
3. Lubricate the auger grease fittings and rotate the auger
to lubricate the auger shaft.
NOTE: Some models are not equipped with grease fittings
and are exempt from this step.
4. Align the shear pin holes. Install the new shear pin (A,
Figure 17) through the auger shaft (C). Secure with a cot-
ter pin (B).
Shear Bolt Replacement
1. Turn off the engine and wait for all moving parts to stop.
2. Remove the existing shear bolt.
3. Lubricate the auger grease fittings. Spin the auger to
lubricate the auger shaft.
4. Align the bolt holes. Install the new shear bolt (A, Figure
18) through the auger shaft (B). Secure with the locknut
(C).
