DRIVE CONTROL AND SHIFT LEVER
ENGLISH
To check the adjustment of the drive control and shift lever, proceed as follows:
1. With the engine off, move the shift lever all the way forward to the highest
speed.
2.
With the drive control released, push the snowthrower forward. The unit should
roll forward. Then engage the drive control. The wheels should stop turning.
3. Now release the drive control and push the unit again.
4. Move the shift lever back to the fast reverse position then all the way forward
again. There should be no resistance in the shift lever, and the wheels should
keep turning.
5. If you feel resistance when moving the shift lever or the wheels stop when they
should not, loosen the jam nut on the drive control cable and unthread (loosen)
the cable one turn.
6. If the wheels do not stop when you engage the drive control, loosen the jam nut
on the drive control and thread in (tighten) the cable one turn.
7. Re-check the adjustment and repeat as necessary.
8. Tighten the jam nut to secure the cable when correct adjustment is reached.
If you are uncertain that you have reached the correct adjustment, proceed as
follows:
WARNING: Drain the gasoline out of the snowthrower’s tank, or place a
piece of plastic lm under the gas cap to avoid spillage BEFORE making the
adjustment.
1. Tip the snowthrower forward, allowing it to rest on the front of the auger
housing (B, g.15).
2.
Remove the frame cover (s, g.15) underneath the snowthrower by removing
the six self-tapping screws.

SHIFT ROD ADJUSTMENT
To adjust the shift rod, proceed as follows:
1. Remove the haipin clip (ee, g.17) and slide the shift rod connector (gg, g.17)
up, to separate the upper shift rod (dd, g.17) from the lower shift rod (ff,
g.17).
2.
Place the shift lever (O, g.17) into the sixth (6) position.
3. Rotate the shift arm clockwise (from the operator’s position) as far as it will go.
4. Thread the upper shift rod downward until the elbow on its lower end aligns
with the hole found in the lower shift rod.
5. Reconnect the upper shift rod to the lower shift rod by reinserting the hairpin
clip removed earlier and sliding the shift rod connector back down into place.
ENGLISH
IMPORTANT: Make certain to check for correct adjustment of the shift rod
!
as instructed under items 1 - 6, Drive Control and Shift Lever, above in the
Adjustment section, before operating the snowthrower.
SKID SHOES
The space between the shave plate and the ground can be adjusted.
For close snow removal on a smooth surface, raise skid shoes (U, g.18) higher
on the auger housing (B, g.18).
Use a middle or lower position when the area to be cleared is uneven.
WARNING: Do not operate this snowthrower on gravel as loose gravel can
!
be easily picked up thrown by the auger causing injury to be operator and/or
damage to the snowthrower.
v.090220 15
ADJUSTMENT
Adjust skid shoes by loosening the four ange lock nuts and carriage bolts.
Move skid shoes to desired position.
Make certain the entire bottom surface of skid shoe is against the ground to
avoid uneven wear on the skid shoes.
Retighten nuts and bolts securely.
CARBURETOR
Minor carburetor adjustment may be required to compensate for differences in
fuel, temperature, altitude and load.
ENGLISH
Refer to the separate engine manual packed with your unit, for carburetor
adjustment information.
MAINTENANCE
WARNING:
Before lubricating, repairing, or inspecting, disengage all controls and stop
engine.
Wait until all moving parts have come to a complete stop.
Disconnect spark plug wire and ground it against the engine to prevent
unintended starting.
Always wear safety glasses during operation or while performing any
adjustments or repairs.
!
LUBRICATION
Engine
Refer to the separate engine manual packed with your unit for all engine lubrication
instructions.
WARNING: If any adjustments need to be made to the engine while the engine
is running (e.g. carburetor), keep clear of all moving parts. Be careful of mufer,
engine and other surrounding heated surfaces.
Gear Shaft
Lubricate the gear shaft with 6-in-1 grease (available at automotive stores) at
least once a season or after every 25 hours of operation
IMPORTANT: Keep all grease and oil off of the rubber friction wheel and
aluminum drive plate.
Chute Directional Control
The worm gear on the chute directional control should be greased with multipurpose
automotive grease.
Gear Case
The gear case is lubricated with grease at the factory and it does not require
checking. If dis-assembled for any reason, lubricated with 60 mL (2 ounces) of
Shell Alvania grease EPB00 or equivalent. Before re-assembling, remove old
sealant and apply new sealant.
IMPORTANT: Do not overll the gear case, since damage to the seals could
result. Be sure the vent plug is free of grease in order to relieve pressure.
