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 goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
n Make sure that all operating and service person-
nel 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 gan-
grene, 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 damage. 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 clearances. Replace any
damaged hoses immediately.
1. Couple the backhoe hydraulic pump to the trac-
tor PTO, if equipped.
2. Insert the pump bracket between the tractor
drawbar support to prevent pump rotation. Engage
the pump PTO coupler 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 sys-
tem is full (approximately 10 US gallons). Check the
tractor hydraulic reservoir and service if necessary.
NOTE: See the BH9000 backhoe operator manual
for hydraulic oil recommendations. Do not mix
hydraulic fluid types.
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 neu-
tral, start the engine and run at low idle.
7. Smoothly engage the PTO pump to provide
backhoe hydraulics.
NOTE: Very little engine power is required to oper-
ate 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 operating position.
