SECTION 4 —MAINTENANCE
4.1 GENERAL
Maintenance personnel responsible for the upkeep of this equipment should possess a
basic understanding of the equipment and normal sequence of operation. Refer to Sec-
tions 1 and 3 of this manual.
Maintenance discussed in this section is divided into two parts — Preventive Mainte-
nance and Corrective Maintenance (Trouble Shooting).
Preventive Maintenance consists of those routines which keep the equipment in proper
working condition. Preventive Maintenance is not only desirable, but is necessary, since
routine inspection will ensure continued trouble-free operation of the equipment and pre-
vent, or at least detect at an early stage, mechanical or hydraulic troubles that might
otherwise develop into equipment malfunction.
Corrective Maintenance (Trouble Shooting) is the examination and repair or replacement
of the part or parts of the equipment that resulted in equipment malfunction.
4.2 SAFETY PRECAUTIONS
WHEN ANY REPAIRS OR ADJUSTMENTSARE MADEAND BODY
IS FULLY OR PARTLY RAISED, BODY MUST BE BLOCKED SE-
CURELY SO IT CANNOT FALL.
4.3 SUGGESTED PREVENTIVE MAINTENANCE PROGRAM
Suggested preventive maintenance checks are listed below.
Perform These Checks Monthly
1) Check bolt tightness at shear bolt at rear, hinge pins, both ends of lever arm shaft,
upper and lower link pins, cylinder upper and lower pins, hold downs, PTO, pump,
cab control and drive line bearing. Self locking nuts are used throughout unit, and
any time a replacement is needed, it must be replaced with an equal part.
2) Inspect drive line for possible wear and check set screws for tightness and lock
wire in position.
3) Check oil level in cylinder for correct height. See Section 2.9.
4) Check color of oil for possible contamination. If oil appears thick or dirty, drain sys-
tem and replace. See Section 4.5 for proper type oil.
5) Check for oil leaks in all hydraulic ttings and hoses. Retighten ttings and replace
hoses as necessary.
CAUTION

-15-
SECTION 4 —MAINTENANCE
4.4 LUBRICATION
The hoist should be lubricated at least once a week. Use same grease as recommend-
ed for chassis. Lubrication points are as follows:
1) Rear hinges...................................1 tting each hinge
2) Lever arm......................................2 ttings
3) Link................................................2 ttings each link
4) Cylinder upper end........................1 tting
5) Cylinder lower end........................ 1 tting
6) U-Joint...........................................1 tting each
7) Drive line bearing..........................1 tting
Use oil on control rail ends, cable, cable lines, and link ends. Hand grease spline and
sleeve.
4.5 HYDRAULIC OIL
When adding or replacing oil, use a hydraulic oil that contains antifoamant, rust and
oxidation inhibitors, and an antiwear additive. If a hydraulic oil is not available, use an
API engine oil, designation SE, with an SAE viscosity rating of 10W30.
DO NOT use low viscosity naphtha base motor oil, hydraulic brake uid, or aircraft
hydraulic uid.
We recommend that the oil in the system be changed at least twice a year.
4.6 CORRECTIVE MAINTENANCE (TROUBLE SHOOTING)
The operation of any mechanical or hydraulic system depends on the life span of the
various parts. Some parts should last indenitely; others may not. This section is a
general guide to the causes of possible equipment malfunction.
Safety
Respect the potential danger of the equipment. Refer to Section 4.2 "Safety Precau-
tions" before starting any repair.
Test Equipment
Use high quality test equipment. Any gage range should be well beyond the expected
test value.
