MAINTENANCE
25
WARNING: Always turn unit off, remove ignition key, and
disconnect the spark plug wire before making any
repairs or adjustments.
This snowthrower is equipped with two height adjust skids, secured
to the outside of the auger housing. These elevate the front of the
snowthrower.
When removing snow from a hard surface area such as a paved
driveway or walk, adjust the skids up to bring the front of the
snowthrower down.
When removing snow from rock or uneven construction, raise the
front of the snowthrower by moving the skids down. This will help to
prevent rocks and other debris from being picked up and thrown by
the augers.
ADJUST SKID HEIGHT
To adjust skids, proceed as follows:
1. Place a block (equal to height from ground desired) under
scraper bar near but not under skid.
2. Loosen skid mounting nuts ( A , Figure 20) and push the skid
down ( B ) until it touches the ground. Retighten mounting nuts.
3. Set skid on other side at same height.
NOTE: Make sure that snowthrower is set at same height on
both sides.
WARNING: Be certain to maintain proper ground
clearance for your particular area to be cleared.
Objects such as gravel, rocks, or other debris, if struck
by the impeller, may be thrown with sufficient force to
cause personal injury, property damage, or damage to
the snowthrower.
1. With the auger control lever released, the hook ( A , Figure 21)
should barely touch the lever ( B ) without raising it. There can
be a maximum of 1/32 in. (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 ).
WARNING: Do not over-tighten, as this may lift the
lever and cause the auger drive to be engaged
without depressing the auger drive control.
AUGER CONTROL CABLE ADJUSTMENT
WARNING: The auger must stop within 5 seconds. If it
does not, see an authorized dealer.
6. Release the auger control lever.
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 authorized
dealer).
AUGER SHEAR PIN REPLACEMENT
The augers are secured to the auger shaft with special shear pins
that are designed to break if an object becomes lodged in the
auger housing. Use of a harder grade shear pin will reduce the
protection provided by the shear pin.
WARNING: Do not go near the discharge chute or
auger when the engine is running. Do not run the
engine if any cover or guard is removed.
Under most circumstances, if the auger strikes an object which
could cause damage to the unit, the shear pin will break. This pro-
tects the gear box and other parts from damage.
The shear pins (
A , Figure 22) are located on the auger shaft. Re-
place a broken shear pin as follows.
1. Tap out the broken shear pin with a pin punch.
2. Install a new shear pin and cotter pin. Bend the ends of the
cotter pin down.
IMPORTANT: Do not replace shear pins with anything
other than the correct grade replacement shear pin. Use
of bolts, screws, or harder grade shear pins can result in
equipment damage.
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 drive control
lever. The auger should engage and run normally.
