hydraulic oil and securely install element over stem in
housing.
6. If necessary, replace O-ring in cover.
7. Reinstall cover and securely tighten.

normal operating pressure and temperature. Check filter
cover and vent plug for leaks. Securely tighten as
required.

Changing Oil
See Figure 2-1 for the following procedure.
Drain and refill the hydraulic system every 1,000 hours or
semiannually, whichever comes first, unless an alternate
interval has been established through an oil analysis
program.
1. Operate crane until hydraulic oil is at normal operating
temperature. This will help prevent impurities from
settling in system.
2. Stop engine.
3. Attach a rubber hose to pipe on drain valve (8) and insert
end of hose into a suitable container to catch hydraulic
oil. See Section 9 for hydraulic system capacity.
4. Open drain valve (8) and drain tank completely.

remove cover. Take care to prevent dust and wind-
blown dirt from entering tank while covers are off.

damaged or clogged holes and for sludge, gum or
lacquer formation. If necessary, clean as follows:
a. Remove cover from bottom of tank.
b. Using a wrench, remove suction filter from inside
tank.
c. Soak in clean, nonflammable solvent. Brush off
outer surface, and flush from inside out. Discard if
damaged.
d. Securely reinstall suction filter.
8. Use new seals and securely fasten access covers to
tank.

Use care not to lose parts inside breather when
cover is removed.

breather when indicated (see instructions earlier in this
section).
11. Replace all four filter elements (1a and 6a) as instructed
earlier in this section.

filters (6).
