Servicing and lubricating the feed screw
• The feed screw is equipped with shear pins (24) that are meant to
shear if the feed screw strikes hard compacted ice or other foreign
objects. The snow blower is supplied with extra shear pins so that they
can be replaced when needed.
Note:
Never substitute the shear pins with ordinary bolts. This can
seriously damage the snow blower if the feed screw becomes stuck
and immovable.
• Unscrew the shear pins once per season and spray inside the shaft
with lubricant. Also lubricate the screw shafts’ flange bearings (25).
Transmission, feed screw and clutch control adjustments
Testing and adjusting the transmission
Follow these procedures:
1. With the engine off, move the shift lever to the highest gear (6th).
Release the drive control lever. The blower should now be in neutral and
freely moveable in both directions.
2. Squeeze the drive control. The blower should now be unable to be
moved forward.
3. Release the drive control and the blower should be freely moveable again.
4. Move the shift lever to one end (reverse 2nd gear) and then to the other
(6th gear). You should feel no resistance in the lever and the blower should
be freely movable regardless of which gear it is in.
Adjusting the shift lever wire
The shift lever has two wires, one for each direction. Make sure that all the gears
work and that the shift lever can be easily moved to its end points (6th gear and
reverse 2nd gear). Use the adjusting nut (26) and screw (27) on one of the wires to
adjust when necessary. Releasing tension in one wire should cause the other one
to become taut.
Feed screw
Adjusting the feed screw control wire:
1. Pull up the dust boot (28) over the wire bracket (29).
2. Pull up on the bottom wire to increase wire slack in the upper wire enabling
you to remove the hook.
3. Turn the bracket over and begin working the s-hook loose from the bracket.
4. Pull the wire taut and insert the hook down a notch on the bracket.
5. Start the engine, check performance and adjust if necessary.
Note: If the feed screws do not turn when engaged then the amount of free
play in the wire is too great. Move the s-hook to a hole further down the bracket
if needed.
Clutch
Adjusting the clutch wire:
1. If the blower has a tendency to move backwards or forwards without having the clutch engaged, then
the wire is too taut. Adjust the wire so that there is some free play in it using the same procedure used for
adjusting the feed screw control wire described above.
2. If the blower does not move backwards or forwards with the clutch engaged, then the wire is too loose.
Tighten by moving the s-hook down a notch on the bracket as described above.
3. Test the clutch and adjust accordingly.
