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.

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

SOURCE OF IGNITION UNTIL GASO-

LINE VAPORS HAVE DISAPPEARED.

Check the fuel level periodically to avoid running out
of gasoline wMle 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 itcan be

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 figure 9.

e Move choke lever to CHOKE position
e Grasp starter handle (see figure 9) 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 In
addition, the flails and fingers will be noisy after the
engine is started, until the impeller reaches full speed.
