To clear snow from crushed rock or gravel, push down
on the handle to raise the rotor blades clear of the
loose material and push the snowthrower forward.

In snowy and cold conditions, some controls and
moving parts may freeze solid. Do not use excessive
force when trying to operate frozen controls. If you
have difficulty operating any control or part, start the
engine and let it run for a few minutes.
•
After clearing the snow, let the engine run for a few
minutes to prevent moving parts from freezing. While
the engine runs, pull the recoil starter two or three
times to prevent it from freezing. Shut off the engine
and remove all ice and snow from the snowthrower.
On models 38441 and 38442: Operate the chute crank
several times to remove any ice and snow.

remove the slack in the cable (Fig. 10 or Fig. 12).
3. Ensure that a 1/16 to 1/8 in. (0.16 to 0.32 cm) gap
exists between the control bar and the handle (Refer to
the inset in Fig. 10). To adjust the cable, go to step 4.
Note: The control cable must have slack in the
disengaged position.
