the machine. Safe service requires your full attention.
Avoid High Pressure Fluids
•Hydraulic hoses and lines can fail due to physical
damage, kinks, age, and exposure. Check hoses and lines
regularly. Replace damaged hoses and lines.
•Hydraulic fluid connections can loosen due to physical
damage and vibration. Check connections regularly.
Tighten loose connections.
•Escaping fluid under pressure can penetrate the skin
causing serious injury. Avoid the hazard by relieving
pressure before disconnecting hydraulic or other lines.
Tighten all connections before applying pressure.
•Search for leaks with a piece of cardboard. Protect
hands and body from high pressure fluids.
•If an accident occurs, see a doctor immediately. Any
fluid injected into the skin must be surgically removed
within a few hours or gangrene may result. Doctors
unfamiliar with this type of injury should reference a
knowledgeable medical source.
Prevent Fires
•Never remove fuel cap or add fuel with engine running
or hot. Allow engine to cool for several minutes.

Safety - 5
SAFETY
•Never store equipment with fuel in the tank inside a
building where fumes may reach an open flame or spark.
•Allow engine to cool before storing in any enclosure.
•To reduce fire hazard, keep engine free of grass, leaves
or excessive grease.
Tire Safety
Explosive separation of a tire and rim parts can cause
serious injury or death:
•Do not attempt to mount a tire without the proper
equipment and experience to perform the job.
•Always maintain the correct tire pressure. Do not inflate
the tires above the recommended pressure. Never weld or
heat a wheel and tire assembly. The heat can cause an
increase in air pressure resulting in a tire explosion.
Welding can structurally weaken or deform the wheel.
•When inflating tires, use a clip-on chuck and extension
hose long enough to allow you to stand to one side and not
in front of or over the tire assembly.
•Check tires for low pressure, cuts, bubbles, damaged
rims or missing lug bolts and nuts.
Handling Fuel Safely
Fuel and fuel vapors are highly flammable and
explosive:
•Do not refuel machine while you smoke, when machine
is near an open flame or sparks, or when engine is running.
Stop engine and allow to cool before filling.
•Never remove the fuel cap or add fuel with the engine
running.
•Never fill fuel tank or drain fuel from a machine in an
enclosed area. Fill fuel tank outdoors.
•Prevent fires. Clean up spilled fuel immediately.
•Do not store machine with fuel in tank in a building
where fumes may reach an open flame or spark.
•Prevent fire and explosion caused by static electric
discharge. Use only non-metal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the
American Society for Testing & Materials (ASTM). If using
a funnel, make sure it is plastic and has no screen or filter.
MIF
•Static electric discharge can ignite gasoline vapors in an
ungrounded fuel container. Remove the fuel container from
the bed of a vehicle or the trunk of a car and place on the
ground away from the vehicle before filling. Keep nozzle in
contact with container opening while filling.
•When practical, remove equipment from trailers or truck
beds and refuel them on the ground. If this is not possible,
use a portable, plastic fuel container to refuel equipment on
a truck bed or trailer.
•For gasoline engines, do not use gas with methanol.
Methanol is harmful to your health and to the environment.
