AUGERCONTROL
CABLE ADJUSTMENT
The length of the auger control cable is adjustable.
However, it will seldom be necessary to change the
cable length since the operating tension on the drive belt
is maintained by the spring on the end of the cable.
If
the auger turns too slowly under heavy load or
momentary squealing of drive belt is heard when
ing heavy snow, pressure applied to drive belt by idler
pulley must be increased by reducing the slack in the
cable.
If the auger continues to turn when the auger control
is released, the cable is too tight. The oressure
to the drive belt must be eliminated by
amount of slack to the cable adjustment.

Start the snow thrower engine and pull back on auger

check to be sure auger stops turning.
If auger continues to turn after auger control is
released, cable is too tight and will have to be adjusted to make it longer. Cable must be slightly slack
when auger control is released (away from handle).
CARBURETOR ADJUSTMENT
The carburetor is properly calibrated and preset at the
factory for efficient cold weather operation. There are no
adjusting screws on the carburetor.
If it is apparent that the carburetor is not providing satisfactory fuel supply to engine, contact your nearest
Authorized Tecumseh Service Outlet for service.
