CONTROL VALVE & HOSE KIT INSTALLATION
Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other
body parts to check for leaks. Wear safety gog-
gles. Hydraulic fluid under pressure can easily
penetrate skin and will cause serious injury or
death.
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.
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.
Make sure all hydraulic hoses, fittings, and
valves are in good condition and not leaking
before starting power unit or using equipment.
Check and route hoses carefully to prevent dam-
age. Hoses must not be twisted, bent sharply,
kinked, frayed, pinched, or come into contact with
any moving parts. Operate moveable components
through full operational range to check clear-
ances. Replace any damaged hoses immediately.
Protective hose sleeves must cover all hydrau-
lic hoses and be secured onto metal hose fittings.
Replace hoses or sleeves if damaged or if protec-
tive sleeve cannot be properly positioned or
secured.
IMPORTANT
■ Hydraulic valves must be connected to the
tractor hydraulic system as shown in this
loader mounting kit manual.
■ If hydraulic lines are not connected as
shown in the mounting kit manual, the loader
control valve may be damaged. A blocked
outlet (Return) or improper hose connection
will cause pressurized oil to enter the return
circuit and damage the valve.
