AND FEATURES

See Figure 7 for all Controls and Features locations.

Traction Drive Clutch - Left Hand Lever

IMPORTANT: Do not "feather" the traction drive clutch 
to control speed or run the unit with the traction drive 
clutch partially engaged. Continued use with the 
traction drive clutch partially engaged will damage the 
transmission.

Squeeze the Traction Drive Clutch 
Lever against the Handlebar (1) to 
engage wheel drive for propelling 
unit. Forward speed will vary 
according to snow depth and 
moisture content. 

Release lever (2) to stop movement.

NOTE: When traveling to or from the 

area to be cleared, press down on the handlebars 
enough to raise the front of the unit slightly off the 
surface, disengage traction drive clutch and push unit 
to new work area.

Attachment Clutch - Right Hand Lever

Squeeze Attachment Clutch Lever 
against handlebar (1) to engage 
attachment. Release both clutch 
levers (2) to disengage power and 
apply brake to attachment.

IMPORTANT: If the belt squeals 
when the attachment clutch lever is 
engaged, the impeller may be frozen 
in the auger housing. Immediately 

release the attachment clutch lever and move the unit 
into a heated area to thaw.

NOTE: If belt squeals when impeller turns freely, see 
Attachment Clutch/Brake Adjustment on page 18.

Ignition Switch (Push/Pull Safety Key)

inserted.

Pushing the primer bulb in adds fuel for 
easier engine start. Refer to Starting and 
Shut Off
 on page 14.

Choke Control Knob

1. Choke Closed position: chokes off 
air to engine for easier start.

2. Choke Open position: allows for 
normal operation.

IMPORTANT: Gradually open choke 
after engine starts.

Throttle

The throttle controls the engine speed. To 
increase or decrease the engine speed, 
adjust to:

1. Fast (normal or warm starts)

2. Part-Throttle

3. Slow (cold weather starts)

4. Stop (engine is off)

The electric starter will start a properly choked and 
cranked engine when the starter button is pushed. 
Refer to Starting and Shut Off on page 14.
