Fuel Shut-Off Valve
(Optional Equipment)
On models so equipped, the fuel shut-off valve, located
under fuel tank, controls fuel-flow from the fuel tank to
the engine. See Figure 6.
Safety Ignition Key
The safety ignition key must be fully inserted and
snapped in place before the unit will start. Remove the
ignition key to prevent unauthorized use of equipment.
See Figure 6.
IMPORTANT: Do NOT attempt to turn the key.
Headlight
The headlight is on whenever the engine is running.
Track Lock Lever
The track lock lever is located on the right side of the
snow thrower and is used to select the position of the
auger housing and the method of track operation. Move
the lever to the right, then forward or backward to one of
the three positions. See Figure 7.
Transport: Keeps the front end of the snow thrower up
for easy transport. May also be used on many gravel
driveways to clear snow while leaving gravel
undisturbed.
Normal Snow: Allows the tracks to be suspended
independently for continuous ground contact.

Packed Snow: Locks the front end of the snow thrower
down to the ground for hard-packed or icy snow
conditions.
