Before You Start
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.
Review all the machine’s safety decals.
Disconnect the unit from the tow vehicle, position it on a
level location and block the wheels front and back to prevent
it from moving.
Ensure you are familiar with safety regulations and shutdown
procedures described in the Operator’s Manual.
Before operating the brush chipper, always wear protective
gear, such as safety goggles, face shield, hearing protection,
tight fitting gloves without draw strings or loose cuffs.
Check the fuel and oil level of the engine, and the hydraulic
fluid in the reservoir.
Adding Fuel
Use unleaded gasoline (87 pump octane minimum). Leaded,
regular gasoline may be used if unleaded us not available.
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.
• Fill the fuel tank outdoors, in an open area, when the
engine is cold. Wipe up any gasoline that spills.
• Never fill the fuel tank inside an enclosed trailer.
• 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.
• 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.
• Always place gasoline containers on the ground away
from your vehicle before filling.
• 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.
• When practical, remove gas-powered equipment from
the truck or trailer and refuel the equipment with its
wheels on the ground.
• If this is not possible, then refuel such equipment on a
truck or trailer from a portable container, rather than
from a gasoline dispenser nozzle.
Using Stabilizer/Conditioner
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
• Cleans the engine while it runs.
• Eliminates gum-like varnish buildup in the fuel system,
which causes hard starting.
Do not use fuel additives containing methanol or ethanol.
Add the correct amount of gas stabilizer/conditioner to the
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.
Filling the Fuel Tank
1. Park the machine on a level surface and stop the engine.
2. Allow the engine to cool.
3. Clean around the fuel tank cap and remove it (Figure 7).

Checking the Engine Oil Level
Changing the Chute Position
The best time to check the engine oil is when the engine is
cool before it has been started for the day. If it has already
been run, allow the oil to drain back down to the sump for at
least 10 minutes before checking. If the oil level is at or
below the “L” mark on the dipstick, add oil to bring the oil
level to the “H” mark. Do not overfill. If the oil level is
between the “H” and “L” marks, no oil addition is required.
The chute on this machine can be rotated to use in various
positions. Rotate to the side, away from the hopper when
using the machine.
1. To rotate, loosen the clamp knob, then press the springloaded button on the locking pin handle IN and pull the
locking pin from the chute plate (Figure 10).

• 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 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, or simply close
the upper chute.
Figure 15
• 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).
• If you jam the machine and do not stop the engine, it can
damage the machine (Figure 16). 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.
