Regular maintenance
of
the loader and hydraulic
system will insure maximum loader efficiency and
long life.
AwARNING
■ Never work under a raised loader.
Always lower loader to ground for service
or
maintenance.
DAILY MAINTENANCE
- Check the level of hydraulic oil in the tractor
before starting each day's operation. If necessary,
add oil
as
recommended in your tractor operator's
manual.
IMPORTANT
■
· When adding oil to the tractor reser-
voir, always use hydraulic oil as specified
for your model tractor.
- After every eight hours of operation, lubricate the
grease fittings at each end
of
each lift boom arm
and at the rod and base end
of
each lift and
bucket cylinder.
- After every ten hours
of
operation, check all
hardware and tighten where required.
- Replace hoses immediately if they are damaged
by a cut
or
scrape, extruded at the fittings, or
leaking. Hydraulic oil leaks should be repaired
promptly
to
avoid loss
of
oil and serious personal
injury from escaping oil.

A CAUTION
■
Keep hands and body away
from
pres-
surized lines. Use paper or cardboard, not
body parts to check for leaks. Hydraulic
fluid (oil) under pressure will penetrate
skin causing serious injury.
■
Make sure that all
o~rating
and
ser"'.
I
vice personnel know that in the event
hydraulic fluid penetrates skin, it must be
surgically removed within a few hours by
a doctor familiar with this form
of
injury, or
gangrene may result.
OIL PRESSURE CHECK
Follow the following procedure
1to
check if the loader
is operating at the correct hydraulic pressure:
Obtain a pressure gauge that registers 3000 PSI in 50
PSI
increments.
Install the pressure gauge into
the
hydraulic line
connecting the loader valve to the base port
of
the
bucket cylinders.
Start
the
tractor engine and adjust the throttle so the
engine is running at operating RPM.
Push bucket control lever to pressurize the hydraulic
line with the gauge attached. Hold
the
control until the
cylinders reach the fully extended position. Holding
the control with the cylinders fully extended will give
you the hydraulic system
pre~ure
on
the gauge.
If the pressure is not correct (416 loader: 1500 psi,
or
417
loader: 2000 psi), contact an authorized service
department.
