Use the tamper to assist in feeding branches into the
chipper chute.
Leaves, twigs and branches up to 1/2-inch in
diameter may be placed into the hopper for shredding.
Never place branches with a diameter
greater than 1/2-inch in the hopper. Doing so can result
in serious damage to your unit's shredder blade, flails
or impeller.
NOTE: In the state of California, the 110000 series
engines covered in this manual are certified by the
California Air Resources Board to meet emissions
standards for 250 hours. Such certification does not
grant the purchaser, owner or operator of this engine
any additional warranties with respect to the
performance or operational life of this engine. This
engine is warranted solely according to the product and
emissions warranties stated elsewhere in this manual.
2-11/16 in. (68 mm)
2-13/64 in. (56 mm)
12.48 cu. in.(206 cc)
For practical operation, the horsepower
loading should not exceed 85% of rated horsepower.
Engine power will decrease 3-1/2% for each 1,000 feet
(300 meters) above sea level and 1% for each 10° F
(5.6° C) above 77° F (25° C). Engine will operate
satisfactorily at an angle up to 15 degrees.
Throttle Lever
The throttle lever controls the engine speed and stop
Choke Control
The choke control closes the choke plate on the
carburetor and aids in starting a cold engine.
Starter Handle

lever, be careful of heated surfaces on muffler
moving the choke lever into the CHOKE
position. Backfire, fire or engine damage
could result.
Gas And Oil Fill-up
Oil (one 20-oz. bottle included)
The chipper shredder is shipped without
oil in the engine.
Type of Oil
1. Refer to the chart below for proper grade of oil.
2. Use a high quality detergent oil classified "For
service SF, SG,SH, SJ" or higher.
3. Do not use special additives.
Synthetic oil meeting ILSAC GF-2, API certification and
API service symbol with "SJ/CF Energy Conserving" or
higher is an acceptable oil at all temperatures. Use of
synthetic oil does not alter required oil change intervals.
SAE Viscosity Grades
5W-30, 10W-30
Synthetic 5W-30, 10W-30
°F -20°
Starting temperature range anticipated before next oil change
CAUTION: Air cooled engines run hotter than automotive
engines. The use of non-synthetic multi-viscosity oils (5W-
30, 10W-30 etc.) in temperatures above 40°F will result in
higher than normal oil consumption. When using a multi-
viscosity oil, check oil level more frequently.
** CAUTION: SAE 30 oil, if used below 40°F, will result in
hard starting and possible engine bore damage due to
inadequate lubrication.
Remove oil fill dipstick.
With the Chipper Shredder on level ground, use a
funnel to fill engine with oil to FULL mark on
dipstick. Capacity is 20 oz. (0.6 liter). 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 contains 20 oz. of oil.
Before operating the chipper shredder, check the
oil level as follows:
Wipe the dipstick with a clean cloth and reinsert it in
the oil fill tube.
When moving throttle control
Never stop the engine by
