Safety
1.1 SAFETY ALERT SYMBOL
The Owner/Operators 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. This signal word is to be limited to the most extreme situations,
typically for machine components that, for functional
purposes, cannot be guarded.
WARNING
Indicates a potentially hazardous situation that, if not avoid-
ed, could result in death or serious injury, and includes
hazards that are exposed when guards are removed. It
may also be used to alert against unsafe practices.
CAUTION
Indicates a potentially hazardous situation that, if not
avoided, may result in minor or moderate injury. It may
also be used to alert against unsafe practices.
1.2 EMISSION INFORMATION
WARNING TO OWNERS REGARDING
ENGINE SPARK ARRESTERS
Under California Law and under the
laws of several other states, you are
not permitted to operate 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 flammable agricultural
crops, without an engine spark arrester in continuous
effective working order.
The engine on your power equipment, like most outdoor
power equipment, is an internal combustion engine that
burns gasoline (a hydrocarbon fuel). Therefore, your
power equipment must be equipped with a spark arrester
muffler in continuous effective working order. The spark
arrester must be attached to the engine exhaust system
in such a manner that flames or heat from the system will
not ignite flammable material.
Failure of the owner/operator of the equipment to comply
with this regulation is a misdemeanor under California law
and may also be a violation of other state and/or federal
regulations, laws, ordinances, or codes. Contact your local
fire marshal or forest service for specific information about
which regulations apply in your area.
The standard muffler installed on the engine is not
equipped with a spark arrester. One must be added
before using this machine in an area where a spark
arrester is required by law. Contact the local authorities
if these laws apply to you. See your authorized engine
dealer for spark arrester options.

13.
ure to do so may cause serious injury or death.
Keep all guards, deflectors, and shields in good work-
14.
ing condition.
Before inspecting or servicing any part of this machine,
15.
shut off the skid steer, disconnect the hydraulics, remove the ignition key and make sure all moving parts
have come to a complete stop.
Check that all screws, nuts, bolts, and other fasteners
16.
are secured, tightened and in proper working condition
before starting the machine and once every 8 hours
of operation.
Do not transport or move machine while the machine
17.
is operating or running.
1.4 OPERATION SAFETY
1.
Always stand clear of discharge area when operating
this machine. Keep face and body away from feed
and discharge openings.
Keep hands and feet out of feed and discharge open-
2.

personal injury. Stop and allow machine to come to a
complete stop before clearing obstructions.
Set up your work site so you are not endangering traffic
3.
and the public. Take great care to provide adequate
warnings.
Do not climb on machine when operating. Keep proper
4.
balance and footing at all times.
Check cutting chamber to verify it is empty before
5.
starting the machine.
The rotor will continue to rotate when clutch is disen-
6.
gaged. Shut off skid steer, disconnect the hydraulics,
remove the ignition key and make sure all moving parts
have come to a complete stop.
Do not insert branches larger than 3 inches in diameter
7.
for the 74500 and 5 inches in diameter for the 74800
into chipper or machine damage may occur.
When feeding material into machine, do not allow
8.
metal, rocks, bottles, cans or any other foreign material
to be fed into the machine.
Ensure debris does not blow into traffic, parked cars,
9.
or pedestrians.
Keep the machine clear of debris.
10.

result in kickback of material through the feed opening.
Shut off machine immediately if the machine becomes
12.
clogged, the cutting mechanism strikes any foreign object,
or the machine starts vibrating or making an unusual
noise. Shut off the skid steer, disconnect the hydraulics,
remove the ignition key and make sure all moving parts
have come to a complete stop. After machine stops:
Inspect for damage.
A.
Replace or repair any damaged parts.
B.

C.
On electric start models, disconnect cables from bat-
13.
tery before doing any inspection or service.
Check blade bolts for proper torque after every 8 hours of
14.
operation. Check blades and rotate or resharpen daily or
as required to keep blades sharp. Failure to do so may
cause poor performance, damage or personal injury and
will void the machine warranty.
1.5 FEED ROLLER SAFETY
The feed roller can cause serious injury or death. Keep
1.
hands, feet and clothing away from the feed roller
chipper blades.
Never climb onto the feed chute when the unit is op-
