Lift Rod Adjustment

MANUAL LIFT MODELS
The lift lever can be placed in one of three notches and
is held in position by the lever latch. (see Figure 8).
When the lever latch is placed in notch 1 the lift lever
should be applying downward pressure on the
snowthrower. In position 2, the "float" position, the
snowthrower/plow should experience negligible upward
or downward pressure. Position 3 should raise the
snowthrower approximately 3 to 3-1/2 " above the
ground.
ELECTRIC LIFT MODELS:
In the fully raised position the snowthrower should be 3
to 3-1/2" off the ground. In the fully lowered position, the
lift rod should slightly compress the spring (C, Figure 7)
creating downward pressure on the snowthrower. If the
snowthrower tilts excessively to one side you may want
to install the spring assist (see installation instructions).
The spring assist is not required on electric lift models.
NOTE: Always adjust the lift height before and after
adjusting the downward pressure.
Lift Height Adjustment
1. Place the lever latch in notch 3 or fully raise the elec-
tric lift (see Figure 8). The snowthrower should be
approximately 3 to 3-1/2" off the ground. If not, go to
step 2.
2. Lower the snowthrower and adjust the front set collar
(A, Figure 7) to achieve the correct lift height.
Downward Pressure Adjustment
1. Move the lever latch from notch 2 to notch 1 (See
Figure 8) or fully lower the electric lift.
2. The spring (C, Figure 7) should be slightly com-
pressed applying downward pressure to the
snowthrower. If not, adjust the rear set collar (D,
Figure 7) to achieve the desired amount of downward
force. Do not over-compress the lift rod spring.
CAUTION
Do not over-compress the lift rod spring. In addition
to providing downward pressure, the spring is an
elastic medium that absorbs shocks caused by
bumps and cracks in ground surfaces. Over-com-
pressing the spring defeats this and could cause
damage to the unit.
