Operation
Before You Start
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.
WARNING
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.
WARNING
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.
• 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.
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.
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
drained.
• 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
gas.
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).

4. Only fill tank to bottom of the fill neck tube, do not
overfill.
Hour Meter
The hour meter records the number of hours the engine has
operated. It operates when the engine is running.
