SUB-FRAME & BACKHOE TO TRACTOR Cont’d
Connect Hydraulic System
n 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.
n 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.
n 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.
1.
Couple the backhoe hydraulic pump to the tractor
PTO.
2. Insert the pump bracket over the tractor drawbar
to prevent pump rotation. Engage the pump PTO cou-
pler pin firmly in the tractor PTO spline groove.
3. Check all hydraulic fittings and lines to be sure
they are tight and free of kinks or twists.
4. Make sure backhoe PTO driven hydraulic system
is full (approximately 5-7 US gallons). Check the trac-
tor hydraulic reservoir and service if necessary.
5. Be sure the backhoe controls are centered in the
neutral position and the backhoe hydraulic pump is
securely mounted to the tractor.
6. With the tractor PTO and transmission in neutral,
start the engine and run at low idle.
7. Smoothly engage the PTO pump to provide back-
hoe hydraulics.
NOTE: Very little engine power is required to operate
the hydraulic system in this mode. Should the engine
pull down excessively, check the plumbing hook-up
for reversed lines or a control lever stuck in an operat-
ing position.
