5. Do not attempt to shred or chip material larger than  
specified on the machine or in this manual. Personal  
injury or machine damage could result.  
6. Never attempt to unclog either the feed intake or  
discharge opening while the engine is running. Shut the

SECTION 4: OPERATING YOUR CHIPPER SHREDDER VACUUM  
Read, understand, and follow all instructions and  
warnings on the machine and in this manual before  
operating. A pair of safety glasses has been  
provided with this equipment.  
Repeat until engine cranks. When engine starts,  
move choke control (if equipped) gradually to RUN  
position.  
NOTE: See your engine manual packed with your unit  
for more detailed instructions.  
WARNING: Always wear safety glasses  
during operation or while performing any  
adjustments or repairs. Thrown objects which  
ricochet can cause serious injury to the eyes.  
To Empty Bag  
Open the large zipper in the rear of the bag to  
empty the contents. Be certain the zipper is closed  
completely when operating the unit.  
Gas & Oil Fill-Up  
If bag is removed for any reason, follow instructions  
for attaching the bag in the ASSEMBLY section.  
Service the engine with gasoline and oil as instructed in  
the engine manual. Read instructions carefully.  
WARNING: Use extreme care when  
handling gasoline. Gasoline is extremely  
flammable and the vapors are explosive. Never  
fuel machine indoors or while the engine is hot  
or running. Extinguish cigarettes, cigars, pipes,  
and other sources of ignition.  
To Engage Drive  
To engage the wheel drive, hold the drive clutch  
control against the upper handle.  
Release the drive clutch control to stop the rear  
wheels from driving.  
Release the drive clutch control to slow down when  
negotiating an obstacle, making a turn, or stopping.  
Engage control slowly to prevent the front wheels  
from lifting up.  
Starting Engine  
WARNING: Keep bystanders, helpers, pets,  
and children at least 75 feet from the machine  
before starting and while operating. Do not  
operate this machine unless the discharge  
chute and bag have been properly installed  
and secured to the machine.  
Using the Chipper Shredder Vacuum  
Place both hands on top of upper handle to push  
unit over yard waste. Yard waste such as leaves  
and pine needles can be vacuumed up through the  
nozzle for shredding.  
Attach spark plug wire to spark plug. Make certain  
the metal cap on the end of the spark plug is  
fastened securely over metal tip on the spark plug.  
Make certain drive clutch control is in the  
disengaged (released) position.  
Engines with choke lever: Move choke lever on  
engine to CHOKE position. (A warm engine may  
not require choking).  
Engines with primer: Prime engine as instructed  
in the engine manual.  
Move engine throttle control lever to FAST or  
START position.  
Place one foot on the left rear wheel to prevent the  
unit from skidding while starting.  
Grasp starter handle and pull rope out slowly until  
engine reaches start of compression cycle (rope  
will pull slightly harder at this point).  
After material has been shredded by the blades on  
the impeller assembly, it will be discharged into  
catcher bag. Do not attempt to shred or chip any  
material other than vegetation found in a normal  
yard (i.e. branches, leaves, twigs, etc.) Avoid  
fibrous plants such as tomato vines until they are  
thoroughly dried out. Materials such as stalks or  
heavy branches up to 3” in diameter may be fed  
into the chipper chute.  
WARNING: Do not attempt to shred, chip, or  
vacuum any material larger than specified on  
the machine or in this manual. Personal injury  
or damage to the machine could result.  
IMPORTANT: The flail screen is located inside the  
housing in the discharge area. If the flail screen  
becomes clogged, remove and clean as instructed in  
the maintenance section. For best performance, it is  
also important to keep the chipper blade sharp.  
NOTE: A noise will be heard at the start of the  
compression cycle, which will continue to be heard till  
the impeller reaches full speed.  
Tire Pressure (Pneumatic tires only)  
Keeping a firm grip on the starter handle, pull rope  
with a rapid, continuous, full arm stroke. Let the  
rope rewind slowly.  
Maximum tire pressure under any circumstance is 30  
psi. Equal tire pressure should be maintained at all  
times.

downwards. Height must be adjusted equally. In  
general, raise the nozzle to vacuum a thick layer of  
leaves and lower the nozzle for smooth surfaces.  
See Figure 9.  
Front Caster Wheels  
Drive Clutch Cable  
This chipper shredder vacuum is equipped with front  
caster wheels. The casters can be locked in a straight  
ahead position or to swivel freely.  
Adjust the drive clutch control if:  
a. the chipper shredder vacuum moves forward  
with the drive clutch control disengaged,  
b. it does not self-propel with the drive clutch  
control engaged, or  
c. drive belt is slipping (unit hesitates while  
engine maintains the same speed).  
Lift and place pins in the larger holes for locked or  
straight ahead operation. See Figure 8.  
a. Place pins in smaller holes to allow casters to  
rotate freely.  
b. Lock wheels in straight position when  
operating on slopes.  
Use the adjustment wheel located in the clutch  
control housing to tighten or loosen the clutch  
cable.  
In addition, the adjustment wheel may also be used  
to determine the position in which the drive clutch  
control is engaged. If it is more comfortable to have  
the drive engaged with the lever further away from  
the handle, tighten the clutch cable. See Figure 10.
