• Fill engine with oil as follows. Remove oil fill dip­
stick. See figure 7. With chipper-shredder level,
use a funnel to fill engine with oil to FULL mark on
dipstick. Capacity is approximately 11/2 pints. Be
careful not to overfill. Tilt chipper-shredder toward
the left (from behind the hopper), then re-level.
Check oil level. Refill to FULL mark on dipstick if
necessary. Replace dipstick and tighten.

• Remove fuel cap and fill fuel tank. See figure 8.
Use fresh, clean, unleaded automotive gasoline.
Capacity is one gallon. Replace fuel cap.
A
WARNING: DO NOT FILL CLOSER
THAN 1/2 INCH OF TOP OF FUEL TANK
TO PREVENT SPILLS AND TO ALLOW
FOR FUEL EXPANSION. IF GASOLINE
IS ACCIDENTLY SPILLED, MOVE CHIP­
PER-SHREDDER AWAY FROM AREA
OF SPILL. AVOID CREATING ANY
SOURCE OF IGNITION UNTIL GASO­
LINE VAPORS HAVE DISAPPEARED.
Check the fuel level periodically to avoid running out
of gasoline while operating the chipper-shredder. If
the unit runs out of gas as it is shredding or chipping,
it may be necessary to unclog the unit before it can be
restarted. Refer to "Removing the Flail Screen” on
page 13.
Caution: Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or methanol)
can attract moisture which leads to separation and
formation of acids during storage. Acidic gas can
damage the fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be
empty before storage for 30 days or longer. Refer to
"Storage” section of this manual for details. Use fresh
fuel each season.
Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may result.
NOTE: USE CLEAN OIL AND FUEL. STORE IN
APPROVED, CLEAN, COVERED CONTAINERS.
USE CLEAN FILL FUNNELS.
TO START ENGINE
WARNING; BE SURE NO ONE OTHER
THAN THE OPERATOR IS STANDING
NEAR THE CHIPPER-SHREDDER
WHILE STARTING OR OPERATING. DO
NOT OPERATE THIS CHIPPER-SHRED­
DER UNLESS THE CHUTE DEFLECTOR
HAS BEEN PROPERLY INSTALLED
AND IS SECURED WITH THE HAND
KNOBS.
• Attach spark plug wire and rubber boot to spark
plug if necessary. See figure 8.
• Place the throttle control lever in FAST position.
See figures 8 and 9.
• Move choke lever to CHOKE position.
• Grasp starter handle (see figure 8) and pull rope
out slowly until engine reaches start of compres­
sion cycle (rope will pull slightly harder at this
point). Let the rope rewind slowly.
NOTE: A noise will be heard when finding the start of
the compression cycle. This noise is caused by the
flails and fingers which are part of the shredding mech­
anism falling into place, and should be expected.
