Drive Control
Refer to "Auger and Drive Control Cables
Section 3 for instructions to adjust the drive control. To further
check the adjustment, proceed as follows:
1.
With the snow thrower tipped forward (be certain to drain
gasoline or place plastic film under the gas cap if the snow
thrower has already been operated), remove the frame
cover underneath the snow thrower by removing the self-
tapping screws. See Fig. 6-6.
Figure 6-6
2.
Locate the opening between the axle support bracket and the
front frame support. See Fig. 6-7. Looking through this
opening, with the drive control released, there must be
clearance between the friction wheel and the drive plate in
all positions of the shift lever.

If there is no friction wheel clearance when the drive
control is disengaged, or the friction wheel does not solidly
contact the drive friction plate when the drive control is
engaged, re-adjust the lock nut on the lower end of the
drive cable following the instructions in the Assembly
section.
5.
Reassemble the frame cover.
Chute Directional Control
The distance snow is thrown can be adjusted by adjusting the
angle of the chute assembly. Move the remote chute lever on the
control panel forward to pivot the upper chute down; move the
lever rearward to pivot the upper chute upward.
The chute directional control is located on the left side of the
snow thrower. To change the direction in which snow is thrown,
crank clockwise to discharge to the left and counterclockwise to
discharge to the right.
Auger Control
Refer to the Assembly and Set-up section for instructions on
adjusting the auger control cable.
Skid Shoes
Refer to the Assembly and Set-up section for instructions on
adjusting the skid shoes.
Tire Pressure
Refer to the tire sidewall for the manufacturer's recommended
tire air pressure. Keep the tires filled to the recommended psi.
If the tire pressure is not equal in both tires, the unit may pull to
one side or the other.
Off-Season Storage
If the snow thrower will not be used for 30 days or longer, follow
the storage instructions below.
1.
Lubricate the machine as instructed earlier in this section.
2.
Store in a clean, dry area.
3.
If storing the snow thrower in an unventilated area,
rustproof the machine using a light oil or silicone to coat
the snow thrower.
4.
Clean the exterior of the engine and the snow thrower.
NOTE: Refer to the Engine Maintenance section for information
on storing your engine.
