•
With the traction control clutch engaged, check if
the friction wheel is contacting the drive plate. See
Figure 23.
•
If adjustment is necessary, loosen the jam nut on
the traction control cable, and thread cable in or out
as necessary.
•
Tighten the jam nut to secure the cable when
correct adjustment is reached. Reassemble the
frame cover with six self-tapping screws.
Figure 23
NOTE:
If you had earlier placed plastic film under the
gas cap, be sure to remove it once the adjustment to
the traction control clutch is done and the snow thrower
frame is re-installed.
Adjusting Auger Clutch
To adjust the auger clutch, refer to the Final
Adjustments in section 3.
Adjusting Shift Rod
•
Remove the hairpin clip and flat washer from the
ferrule and remove the ferrule from the shift lever.
Place the shift lever in the fastest forward speed
position.
Models 602, 642, 662:
•
Push up on the shift arm assembly as far as it will
go. Thread the ferrule up or down the shift rod and
align with the lower hole on the wider side of the
shift lever assembly behind the handle panel.
Secure the ferrule to the shift arm assembly again
with the hardware earlier removed. Refer to Figure
8.
Models 614, 644, 664, and 6A4:
•
Push down on the shift arm assembly as far as it
will go. Thread the ferrule up or down the shift rod
and align it with the hole closest to the shift knob on
the narrow side of the shift lever assembly behind
the handle panel. Refer to Figure 9.
NOTE:
Make certain to check for correct adjustment
of the shift rod as instructed in the Final Adjustments
section before operating the snow thrower.
Carburetor Adjustment
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 muffler, engine
and other surrounding heated surfaces.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude and load.
Refer to the separate engine manual packed with your
unit for carburetor adjustment information.
Drive Wheels
The wheels may be adjusted for two different methods
of operation. The adjustment is made by placing the
klick pins in one of two different holes on the right side
of the unit. See Figure 24.
•
One Wheel Driving-Place klick pin in the outside
axle hole on the right side. This position gives
power drive to the left wheel only, making the unit
easier to maneuver.
•
Both Wheel Driving-Place klick pin in the hole in
the hub next to the rim on the right side. This
position is good for heavy snow as there is power
drive in both wheels.
