Gas And Oil Fill-up
Oil (one 20-oz. bottle shipped with unit)
Only use high quality detergent oil rated with API
service classification SF, SG or SH. Select the oil’s
viscosity grade according to the expected operating
temperature. Follow the chart below.
NOTE: Although multi-viscosity oils (5W30, 10W30,
etc.) improve starting in cold weather, these
multiviscosity oils will result in increased oil
consumption when used above 32"F. Check engine
oil level more frequently to avoid possible engine
damage from running low on oil.

Oil Viscosity Chart
• Remove oil fill dipstick.
• With the chipper-shredder vacuum on level
ground, use a funnel to fill engine with oil to
FULL mark on dipstick. Capacity is
approximately 20 oz. Be careful not to overfill.
Overfilling will cause the engine to smoke
profusely and will result in poor engine
performance. The oil bottle packaged with your
chipper-shredder vacuum contains 20 oz. of oil.
• Tilt chipper-shredder vacuum toward the left,
then re-level. Check the oil level making certain
not to rub the dipstick along the inside walls of
the oil fill tube. This would result in a false
dipstick reading. Refill to FULL mark on dipstick,
if necessary. Replace dipstick and tighten.
• Check oil level three times prior to starting
engine to be certain you’ve gotten an accurate
dipstick reading. Running the engine with too
little oil can result in permanent engine damage.
Gasoline
•
Remove fuel cap from the fuel tank.
• Make sure the container from which you will
pour the gasoline is clean and free from rust or
foreign particles. Never use gasoline that may
be stale from long periods of storage in its
container. Gasoline that has been sitting for any
period longer than four weeks should be
considered stale.
• Fill fuel tank with approximately 3 quarts of
clean, fresh, lead-free grade automotive
gasoline. DO NOT use Ethyl or high octane
gasoline. Replace fuel cap.

WARNING: Never fill the fuel tank indoors.
Gasoline produces noxious fumes. Always
be certain to fill the fuel tank in a well
ventilated area to avoid inhalation of
gasoline fumes.
WARNING: Never smoke while fueling
your chipper-shredder vacuum. Gasoline
produces cumbustable fumes which can
ignite and cause personal injury.
WARNING: Do not fill closer than 1/2 inch
from the top of the fuel tank to prevent
spills and to allow for fuel expansion. If
gasoline is accidently spilled, move
chipper-shredder vacuum away from area
of spill. Avoid creating any source of
ignition until gasoline vapors have
disappeared.
• Check the fuel level periodically to avoid running
out of gasoline while operating the chipper-
shredder vacuum. If the unit runs out of gas as it
is chipping, it may be necessary to unclog the
unit before it can be restarted. Refer to
Removing the Flail Screen on page 15.
Starting The Engine
IMPORTANT: If your unit shows any sign of motion
with the drive clutch control in the disengaged
position, shut the engine off immediately. Readjust
following the instructions on page 16.

WARNING: Make sure that no one other
than the operator is standing near the
chipper-shredder vacuum unit while starting
or operating.
Do not operate this unit unless the nozzle,
discharge chute, and the bag have been
properly installed.
Attach spark plug wire and rubber boot to spark
plug if not already attached.
Place the throttle control lever in FAST position.
Depress the primer three to four times slowly.
Wait about two seconds between each push.
When temperature is at or below 50°F/10°C, it
may be necessary to depress the primer five to
six times. You may have to use the primer to
restart a warm engine after a short shutdown.
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.
The rope will pull slightly harder at this point. Let
the rope rewind slowly.
