Adding Fuel
Using Stabilizer/Conditioner
Use unleaded gasoline (87 pump octane minimum). Leaded,
regular gasoline may be used if unleaded is not available.
Use a fuel stabilizer/conditioner in the machine to provide
the following benefits:
• Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank
be drained.
• Cleans the engine while it runs.
• Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting.
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or explosion
from gasoline can burn you and others and can
damage property.
Important: Do not use fuel additives containing
methanol or ethanol.
• Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline
that spills.
Add the correct amount of gas stabilizer/conditioner to the
• Never fill the fuel tank inside an enclosed trailer.
Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of varnish
deposits in the fuel system, use fuel stabilizer at all times.
• Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to
1/2 inch (6 to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
gasoline to expand.
Filling the Fuel Tank
1. Park the machine on a level surface, and stop the
2. Allow the engine to cool.
3. Clean around the fuel tank cap and remove it (Figure 7).
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
• Store gasoline in an approved container and
keep it out of the reach of children. Never buy
more than a 30-day supply of gasoline.
• Do not operate without entire exhaust system in
place and in proper working condition.
In certain conditions during fueling, static
electricity can be released causing a spark which
can ignite the gasoline vapors. A fire or explosion
from gasoline can burn you and others and can
damage property.
Figure 7
• Always place gasoline containers on the ground
away from your vehicle before filling.
1. Fuel tank cap
• Do not fill gasoline containers inside a vehicle or
on a truck or trailer bed because interior carpets
or plastic truck bed liners may insulate the
container and slow the loss of any static charge.
4. Add unleaded gasoline to the fuel tank, until the level
is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of
the filler neck.
• If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times until
fueling is complete.
Important: This space in the tank allows gasoline
to expand. Do not fill the fuel tank completely full.
5. Install the fuel tank cap securely, turning it until it clicks.
6. Wipe up any gasoline that may have spilled.
Important: Do not use methanol, gasoline containing
methanol, or gasohol containing more than 10% ethanol
because the fuel system could be damaged. Do not mix
oil with gasoline.
Hour Meter
The hour meter records the number of hours the engine has
operated. It operates when the engine is running.

4. Lower the hopper (Figure 14).
• To move a pile of processed material, use a spade,
rake, or long handle tool. Never use you hands or
• Limit the length of large branches to 3 feet long
or less; longer lengths could cause the chipper to
slow and jam.
• Wash out the cutting chamber after each use by
spraying water from a garden hose into the hopper
while the engine is running at full throttle. Do
this for a few minutes to prevent accumulation of
matter that can degrade the chipper performance.
• To stop the machine; refer to
Figure 14
Stopping the Engine (page 13).
• Do not force material into the chipper. If the
machine does not chip well, the chipper knife or
cutter block may need to be sharpened or replaced.
Extremely hard knots of wood will not process very
well. Short stubs that have not self-fed through
the chipper can be pushed through with the next
branch to be chipped, otherwise simply close the
upper chute.
Overloading the hopper will cause the rotor speed
to decrease. If you hear the engine RPM decreasing,
stop feeding material into the hopper until the
engine has returned to full speed (Figure 15).
Figure 15
• If you jam the machine and do not stop the engine,
it can damage the machine. For this reason, it is
important that you immediately stop the engine if
the machine becomes jammed, wait five minutes to
make certain the flywheel and all moving parts have
come to a complete stop and cool. Disconnect
the spark plug wires, keeping them away from the
spark plugs to prevent accidental starting.
Never allow processed material to build up within 3
in (76.2 mm) of the discharge chute opening. Move
the Brush Chipper or the pile as needed. Failure to
