WARNING: Personal injury and/or
damage to the unit could result if you try to
feed any material other than specified.
•
For best performance, keep the chipper blades
sharp.
•
If the discharged material starts to become
stringy, or if the rate of discharge slows down
considerably, the chipper blades may have
become dull. To sharpen or replace the blade,
refer to Service and Adjustment section on
page 15.
•
If the flail screen, located inside the housing in
the discharge area, becomes clogged, remove
the screen and clean. For instructions on
cleaning the screen, refer to the Service and
Adjustment section on page 15.
NOTE:
Care should be taken not to shut off the
engine or to run out of gasoline while operating the
chipper-shredder.
•
Check the fuel level periodically to avoid running
out of gasoline.
•
To eliminate the possibility of jamming, never
turn engine off until all chipping is completed.
If the unit runs out of gas or is turned off as it is
shredding or chipping, it may be necessary to unciog
the unit before it can be restarted. Refer to “Removing
the Flail Screen” in Service and Adjustment section
on page 15.
Drive Clutch Control
Squeezing the drive clutch control engages the drive
mechanism to the rear wheels and causes the
chipper-shredder vacuum to self-propel. Release the
drive clutch control slightly to slow down the chipper-
shredder vacuum’s ground speed when negotiating
an obstacle or making a turn. Release the drive clutch
control completely to stop the rear wheels from
driving. See Figure 12.

Front Caster Wheels
Your chipper-shredder vacuum is equipped with
caster front wheels. The casters can be locked in a
straight ahead position or can be left to swivel freely.
• Lift and place pins in the larger holes for locked,
straight ahead operation. Place pins in smaller
holes to allow casters to rotate freely for more
manueverability. See Figure 13. Lock wheels in
straight position when operating on slopes.
