Safety Rules 6
MAINTENANCE (cont’d)
moveable parts even when the engine has been
turned off. Hydraulic system leak down, hydrau-
lic system failures, mechanical failures, or move-
ment of control levers can cause equipment to
drop or rotate unexpectedly and cause severe
injury or death.
• When performing maintenance or repairs make
sure the equipment is in the lowered
position and both the mainframe and gangs are
properly blocked and secured to prevent rolling.
Failure to do so can cause serious injury or
death.
• Make sure attachment is properly secured,
adjusted, and in good operating condition.
• Before leaving operator’s seat, lower the lift
carriage and put attachment on the ground.
Engage brake, stop engine, remove key, and
remove seat belt.
• Never perform service or maintenance with
engine running.
• Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or
other body parts to check for leaks. Wear safety
goggles. Hydraulic fluid under pressure can eas-
ily penetrate skin and will cause serious injury or
death.
• Air in hydraulic systems can cause erratic
operation and allows loads or equipment compo-
nents to drop unexpectedly. When connecting
equipment or hoses or performing any hydraulic
maintenance, purge any air in hydraulic system
by operating all hydraulic functions several
times. Do this before putting into service or
allowing anyone to approach the equipment.
• Route hydraulic hoses carefully to prevent
damage. Hoses must not be twisted, bent sharp-
ly, kinked, frayed, pinched, or come into contact
with any moving parts. Operate moveable com-
ponents through full operational range to check
clearances. Replace any damaged hose imme-
diately.
• Do not connect a low-pressure hydraulic hose
into a high-pressure system—it will burst the
hose. Do not use a high-pressure hose in place
of a low pressure hose—it is possible to rupture
the valve.
• Make sure that all operating and service per-
sonnel know that if hydraulic fluid penetrates
skin, it must be surgically removed as soon as
possible by a doctor familiar with this form of
injury or gangrene, serious injury, or death will
result.
CONTACT A PHYSICIAN IMMEDIATELY IF
FLUID ENTERS SKIN OR EYES. DO NOT
DELAY.
• Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
• Tighten all bolts, nuts, and screws to torque
chart specifications (page 16). Check that all
cotter pins are installed securely to ensure
equipment is in a safe condition before putting
unit into service.
STORAGE
• Block equipment securely for storage in the
lowered position.
• Keep children and bystanders away from stor-
age area.
