MACHINE PRECAUTIONS
Hot Material PrecautionsHot Material Precautions
• Allow machine to cool before repairing or maintaining
working components.
• DO NOT remove radiator cap, drain plugs, service
grease ttings, or pressure taps while engine is hot.
Add coolant to the radiator and perform other services
only when the engine is stopped and fully cooled.
Hydraulic Systems PrecautionsHydraulic Systems Precautions
• Ensure all components are in good working condition.
Replace any worn, cut, abraded, attened or crimped
hoses and metal lines.
• DO NOT attempt makeshift repairs using tape, clamps
or cements. The hydraulic system operates under
extremely high pressure and such repairs could
cause serious injury.
• Wear proper hand and eye protection when checking
for a high pressure leak. Use a piece of wood or
cardboard as a back stop to isolate and identify leaks.
Hydraulic oil under pressure can
cause serious personal injury. Check for oil leaks
with a piece of cardboard. DO NOT expose hands to
possible high-pressure oil. Turn off engine before
attempting to tighten oil lines and ttings.
• Escaping pressurized hydraulic uid has force
sufcient to penetrate the skin, which could cause
serious personal injury. Ensure all pressure is
relieved before disconnecting line, hoses or valves.
• If injury from concentrated high pressure steam
or hydraulic uid occurs, seek medical attention
immediately. Injuries resulting from hydraulic uid
penetrating the skin’s surface can result in serious

Tire PrecautionsTire Precautions
DO NOT mount or demount tires
without proper training. A violent explosion can
occur.
Follow all procedures and safety instructions. Charts
containing mounting and demounting instructions are
available from OSHA at www.osha.gov/pls/publications.
Contact your authorized dealer or
a qualied tire dealer or repair service to perform
required tire maintenance.
• Clean rims and repaint to stop corrosion and facilitate
checking air level and tire mounting. Be careful to
clean all dirt and rust from the lock ring and gutter.
This is important to secure lock ring in its the proper
position.
• Check rim components periodically for cracks.
Replace all cracked, badly worn, severely rusted, and
otherwise damaged components with new parts of the
same size and type. If you are not sure about proper
mating of tire and wheel parts, consult your authorized
dealer or a wheel and rim expert.
DO NOT attempt to rework, weld,
heat or braze any rim components that are cracked,
broken or damaged. Replace damaged components
with new parts of the same size and type. Mixing
parts of one type with those of another is potentially
dangerous.
DO NOT reinate a tire that has been
run at without rst inspecting the tire, tube, ap, rim,
and wheel assembly. Double-check the side ring and
O-ring for damage, ensuring they are secured in the
gutter before ination.
Mismatched rim parts are dangerous
and could cause SEVERE injury.
• Remove valve core to exhaust all air from tire.
ALWAYS exhaust all air from tire prior to removing
rim components or wheel components such as nuts
or rim clamps. Check the valve stem by running a
piece of wire through the stem to make sure it is not
plugged.
• DO NOT attempt to demount a tire unless you have
the proper equipment and experience to do the job.
• DO NOT try to seat rings or other components by
hammering unless tire is fully deated. Double-check
all components prior to ination.
• DO NOT inate a tire before all components are
properly in place. Recheck components for proper
assembly. If improperly assembled, deate and
correct.
• Never hammer on a tire/rim assembly that is not fully
deated. If assembly is proper at 10 psi (68,947.572
Pa), continue to inate to fully seat the tire beads. Then
completely deate the tire to prevent overly stretching
the tube. Reinate to recommended operating
pressure.
• NEVER sit on or stand in front of a tire/rim assembly
during ination. Use a clip-on chuck and make sure
ination hose is long enough permit the person
inating the tire to stand to the side of the tire.
• DO NOT hammer components with steel hammers.
Use rubber, lead, plastic, or brass-faced mallets to tap
components together.
• DO NOT try to drive an assembled or partially-
assembled tire or rim over a cast spoke wheel by
hammering. DEFLATE and examine to determine
the reason for the improper t. Look for distortion or
components that are not properly locked or sealed.
• Block the tire and wheel on opposite sides of the
vehicle before you place the jack in position. Always
put hardwood blocks under the jack and crib up the
vehicle in case the jack slips.
• DO NOT inate tires beyond the maximum
recommended ination pressure.
• NEVER operate a vehicle on a single tire of a dual
assembly. The carrying capacity of the single tire and
rim is dangerously exceeded and operating a vehicle
in this manner can result in damage to the rim and tire.
