USERS MANUAL
MACHINE MAINTENANCE
Check And Inspect
These components should be checked 'monthly' and
anytime a problem is suspected.
Tower Chains, Tie-Down Chains
The tower chains/hooks and tie down chains/hooks
supplied with the EZ Liner S21M are high quality,
high strength chains/hooks. If replacement is
required, purchase only the original Chief product
from an authorized Chief Automotive Systems, Inc.
representative.
CAUTION:
1. DO NOT heat chain or hook while repairing vehicle
— 600F (316C) of heat on chain will weaken it.
2. DO NOT tip load chain hook. Tip loading chain hook
will stress hook beyond its designed capability and
could cause hook to fail.
3. DO NOT pull with twisted chain links. Pulling with
twisted chain 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 chain.
Safety Ramp
Inspect safety ramps making sure they lift into posi-
tion each time the machine is raised. Lubricate hinges
and other moving parts with oil if they do not lift into
position.
Pedestal Bolts
Remove pump lid and check mainframe to pedestal
bolts/ nuts for looseness.
Power and Control Cords
Inspect power and control cords for worn insulation or
other damage. If found, replace cord(s).
Tower To Mainframe Gap
Measure gap between top of tower gusset and bottom
of mainframe. If gap measures between 5/16 inch
(8mm) and 7/16 inch (11mm), see Tower Tie Bolt
Usage, Page 7. If gap exceeds 7/16 inch (11mm), see
Troubleshooting Section — Tower To Mainframe Gap,
Page 16.
