Machine Maintenance
Check And Inspect
These components should be checked prior to use and anytime a prob-
lem is suspected.
CAUTION: To avoid personal injury when performing
any maintenance function, always wear
safety glasses and safety shoes.
Tower Chains, Tie-Down Chains
The tower chains/hooks and tie-down chains/hooks supplied with the
Chief PHOENIX are high quality, high strength chians/hooks. If replace-
ment is required, purchase only the original Chief product from an
authorized Chief Collision Technology representative.
CAUTION: To avoid personal injury or damage to
property:
• DO NOT Heat chain or hook while repairing
vehicle.
• DO NOT Tip load chain hook. Tip loading chain hook
will stress hook beyond its designed capability and
could cause hook to fail.
• DO NOT Pull with twisted chain links. Pulling with
twisted links will stress chain links beyond their
designed capability and could cause chain to fail.
Tower chains must be inspected for wear, nicks, gouges, stretched and
bent links. If found, replace chain.
Tower chain hooks must be inspected for twist and stretched openings. If
found, replace them.
Loading Ramps
Inspect loading ramps making sure loading ramp pins mate with pinning
holes at rear of machine and all hardware is securely in place each time
mainframe is raised or lowered.
Tower Rollers
Inspect inside and outside tower roller wheels for damage. The inside
and outside roller bearings are lubrication free. Use com-pressed air to
clean. DO NOT lubricate.
Power and Control Cords
Inspect power and control cords for worn insulation or other
damage. If found, replace cord(s).
Cleaning and Lubricating
These components should be cleaned and lubricated as specified for
trouble free operation and extended service. When lubricating use the
following:
Oil — Use 30 weight motor oil for all components requiring oil.
Grease — Use a SUS750 Lithium type grease such as lubricate #630-2 for
all components requiring grease.
Tower Heads
Clean tower heads annually.
1. Remove tower chain from tower head.
2. Remove tower head from tower pipe.
3. Clean dirt from tower head pipe and where tower head
pipe rubs on inside of tower pipe.
4. Apply grease to tower head pipe.
5. Reinstall tower head and tower chain.
Tower Collars
Clean and lubricate collars monthly.
1. Use compressed air to blow out dirt or dust that collects
between collar ears and rollers.
CAUTION: Wear safety glasses while using com-
pressed air to blow out dirt and dust.
2. Place a few drops of oil on roller pin between roller and
collar ears (each side). Then turn roller a few times.
Roller must turn freely.
Eliminating Air In Hydraulic System
All air has been removed from hydraulic system at the factory, but if
hydraulic system is opened to replace a system component, it is
necessary to bleed air from system prior to using it.
Bleeding Air In System At Tower Cylinder
1. Connect tower auxuliary line to mainframe and open auxiliary
line valve.
2. Remove tower head and chain.
3. Fully extend tower cylinder by depressing and holding “UP”
button on hand-held pendant until tower gauge shows 5 tons
of pressure on system.
4. While holding rag over the top of the cylinder to prevent oil
spray, use a 3/16” T-handle allen wrench, loosen cylinder top
bolt 1/2 turn.
5. Rapid, side-to-side motion of the T-handle may be necessary to
unseat the seal washer at the top of the cylinder.
CAUTION: Wear safety glasses to protect eyes from hydraulic
oil in the event it squirts past rag.
6. Trapped air or trapped air/oil mixture (indicated by foam in the
oil) should escape from top of cylinder. Wipe up any escaping
oil with rag.
7. When cylinder is completely bled, only clean oil should escape
from top of cylinder.
NOTE: It may be necessary to tighten top cylinder bolt and repressurize
the system to 5 tons and repeat procedure.
8. Replace tower head and chain. Lower tower cylinder and refill
reservoir to within 1/2” of fill port with all cylinders in retracted
position.
