Bolens 933 SWE Snow Blower User Manual


 
Operating Tips
NOTE: Allow the engine to warm up for a few minutes.
The engine will not develop full power until it reaches
operating temperature.
WARNING: The temperature of the muffler
and the surrounding areas may exceed 150° F.
Avoid these areas.
If possible, remove snow immediately after it falls.
Discharge snow downwind whenever possible.
Slightly overlap each previous path.
Set the skid shoes 1/4” below the shave plate for
normal usage. Adjust them upward for hard-packed
snow and downward when using on gravel or
crushed rock.
Replacing Shear Pins
Each of the four auger spiral assemblies are secured to the
spiral shaft with a shear pin and cotter pin. If the auger
should strike a foreign object or ice jam, the snow thrower
is designed so that the pins may shear. If the augers will
not turn, check to see if the pins have sheared. See Fig. 5-1.
CAUTION: NEVER replace the auger shear pins
with anything other than OEM Part No. 738-
04155 replacement shear pins. Any damage to
the auger gearbox or other components as a
result of failing to do so will NOT be covered by
your snow thrower’s warranty.
WARNING! Always turn off the snow thrower’s
engine and remove the key prior to replacing
shear pins.

To Engage Drive
With the throttle control in the Fast (rabbit) position,
move shift lever into one of the six forward (F)
positions or two reverse (R) positions. Select a speed
appropriate for the snow conditions and a pace
you’re comfortable with.
NOTE: Use slower speeds in higher snow and/or until you
are familiar with the snow thrower operation
Squeeze the drive control against the handle the
snow thrower will move. Release it and drive motion
will stop.
CAUTION: NEVER move the shift lever without
first releasing the wheel drive control. Doing so
will cause premature wear on the drive system’s
friction wheel
To turn the snow thrower to the left or right, squeeze
the respective wheel steering control. Refer to Figure
4-1.
To Engage Augers
To engage the augers and start throwing snow,
squeeze the auger control against the left handle.
Release to stop the augers.
While the auger control is engaged, squeeze the drive
control to engage the interlock mechanism and to
drive the snow thrower. The interlock mechanism
locks the auger control so you can turn the chute
control without interrupting the snow throwing
process.
Release the auger control; the interlock mechanism
should keep the auger control engaged until the
drive control is released.
Release the drive control to stop both the augers and
the wheel drive. To stop the auger, both levers must
be released.
