NOTE: V\fi}ile the engine is reaching №te compressk>n
cycle, you may hear a “clanking“ ncHse. Thisnaseis
caus^ by the impeller flails («voting and falling into
place and IS normal. This noise will continue untill the
impeller reaches full speed.
•
Pull the rope with a rapid, continuous, full arm
stroke while keeping a firm grip on the starter
handle.
•' Continuing to keep a firm grip on the starter
handle, let the rope rewind slowly. Do not let the
starter handle snap back against the eye bolt on
the handle. Repeat, if necessary, until engine
starts. Additional priming may be necessary.
• Move throttle control to IDLE position for a few
minutes to warm up the engine. Move it back to
fast when running.
• ALWAYS keep the throttle control in the Fast
postion when operating the chipper-shredder
vacuum.
NOTE:
Engine may run very slowly for the first five to
ten seconds after it has been started until the impeller
gains momentum and allows the engine to reach its
top RPM .
NOTE:
To idle smoothly, a new engine may require 3
to 5 minutes of running at above the slow idle speed.
The idle speed has been adjusted for proper running
after this break-in period.
Stopping the Engine
• Move throttle control lever to STOP position.
• Disconnect spark plug wire and move away from
the spark plug to prevent accidental starting while
the equipment is unattended.
Adjusting Nozzle Height
• The nozzle door height adjustment levers have
five position settings and are found each side of
the nozzle door. See Figure 10. The nozzle door
height should be adjusted according to the
conditions.
• Slide the height adjustment lever forward or
backward for adjusting the nozzle door upwards
or downwards. See Figure 10.

WARNING: Keep your hands, feet and
any loose clothing clear of the nozzle any
time the engine is running. When the
engine Is running, a vacuum Is being
created in the nozzle which can draw in
loose clothing.
WARNING: Never make any adjustments
on the nozzle while the engine is running.
NOTE: Raise the nozzle height to vacuum a thick
layer of leaves; lower the nozzle height for smoother
lawns.
Operation of your
Chipper-Shredder Vacuum
Your chipper-shredder vacuum is designed to chip
small tree branches and twigs, shred leaves and
vacuum foliage and other lawn debris. For
convenience in operation, your Craftsman chipper­
shredder vacuum is equipped with a drive clutch
control allowing it to "self-propel."
WARNING: The impeller (chipping/
shredding mechanism) is rotating at all
times when the engine is running.
WARNING: Keep your hands away from
the nozzle opening and NEVER place your
hands or arms inside Of the chipper chute
when the engine is running. Doing so could
result in serious personal injury.
IMPORTANT : Your chipper-shredder vacuum is
equipped with a safety switch at the front left portion
of the impeller housing. The metal fab bn'the nozzle
must depress this switch for the engine to start. Be
certain the nozzle is properly in place before
attempting to start the unit. See Figure 4 on page 6.
WARNING: Always survey the area to be
vacuumed thoroughly before operating the
chipper-shredder vacuum. Clear the area
of any obstructions such as toys, dog
chains, etc. Running over such an
obstruction can result in personal injury as
well as damage to the chipper-shredder
vacuum.
Do not vacuum up anything other than normal
yard waste such as leaves or pine needles.
