1.1 SAFETY ALERT SYMBOL
The Owner/Operator’s manual uses this symbol to alert
you of potential hazards. Whenever you see this symbol,
read and obey the safety message that follows it. Failure
to obey the safety message could result in personal injury,
death or property damage.
DANGER
Indicates an imminently hazardous situation that, if not
avoided, will result in death or serious injury.
WARNING
Indicates a potentially hazardous situation that, if not
avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate injury.
1.2 FIRE HAZARD INFORMATION
Federal, state, and local laws may prohibit the operation
of an internal combustion engine using hydrocarbon
fuels on any forest covered, brush
covered or grass covered land or on
land covered with grain, hay or other
ammable agricultural crops, without
an engine spark arrestor in continuous
eective working order.
The engine on your power equipment,
like most outdoor power equipment, is an internal
combustion engine that burns gasoline or diesel fuel
(hydrocarbons). If operating your power equipment in
aected areas, it must be equipped with a spark arrestor
in continuous eective working order. The spark arrestor
must be attached to the engine exhaust system in such a
manner that ames or heat from the system will not ignite
ammable material.
Failure of the owner/operator of the equipment to comply
with federal, state, and local laws may subject him or her
to nes and/or other penalties. Contact your local re
marshal or forest service for specic information about
which regulations apply in your area.
The standard muer installed on the engine is spark
arrestor capable. Spark arrestors require regular
maintenance. See the Service & Maintenance section of
this manual for more information.
Contact local re authorities for laws or regulations
regarding re prevention requirements.

WARNING
Do not tip machine onto its side or turn machine upside
down during assembly. Machine must be assembled in
an upright position.
2.1 NON-CE COMPLIANT ASSEMBLY
2.1.1 INSTALL LEG STAND, AXLE AND
WHEELS
1. Align holes in chipper base (1) with the holes in
axle weldment (2) and the support leg (3). Secure
assembly to chipper base with two 5/16-18 x 2-1/4"
hex head bolts (4) and ange nuts.
2. Secure support leg to the base of the housing body
(5) with two 5/16-18 x 1-3/4" hex head bolts (6), and
ange nuts.
3. Complete by bolting wheels (7) to axle weldment
using two 5/8 x 3" hex head bolts (8).
4. The axle bolts turn into centerlock nuts in the ends of
the axle bar and consequently turn fairly hard. Care
must be taken not to over tighten the bolts or bearing
damage will occur. A properly tightened bolt will allow
minimal side to side movement of the wheel while
allowing the wheel to spin freely.
WARNING
If any bolts or nuts are dropped in the machine, be
sure to remove them before starting the machine.
Remove items from the shredder area by removing the
discharge screen.
2. Install eight 5/16-18 x 3/4" carriage bolts (15) so the
