Drive Control Cable Tension
Adjustment
WARNING! Entanglement Hazard - Before
performing any adjustment procedures, make
sure the engine is off and remove the spark
plug wire from the spark plug to ensure the
engine cannot accidently start. Never adjust
cable tension with the engine running.
The drive control cable is located on the right
side (when standing behind the snow blower)
and is made up of an upper and lower cable
connected by an adjustment plate. The
adjustment plate is located in-line with the cable
below the control handle and is covered by a
black plastic slip cover. The adjustment plate is
used to adjust the drive control cable drive wheel
friction tension.
1. Stop the engine.
2. Disconnect the upper cable from the drive
control handle.
3. Slide up the slip cover to access the
adjustment plate.

5 – Adjustment Plate Lower Cable Opening
4. Adjustment is made by changing the position
of the lower cable in the adjustment plate
holes (1 to 9). Only move the lower cable
diagonally one hole at a time from its original
position.
Note: The upper cable end must be in the
upper single center hole of the adjustment
plate. Do not change the position of the upper
cable.
5. Connect the upper cable to the control handle.
6. Start the engine and engage the drive control
handle to test the operation of the drive
engagement.
Note: With the drive control handle at the full
released position, the cable should be barely
tight. Some slack in the cable may be
required to ensure the drive control is not
engaging the drive friction wheel. There
should be no drive movement with the drive
control handle released. If the drive is
engaged when the drive control handle is
released, loosen the cable tension by
readjusting the cable as necessary. Do not
over tension the cable.
Drive Speed Control Cable
Adjustment
WARNING! Entanglement Hazard - Use
caution when performing the speed control
cable adjustment.
The speed control lever is connected to two
cables that work in tandem to control machine
speed and direction. As the speed control lever is
moved from forward to reverse gears (right to
left) one cable is pulled and one is pushed.
