LG TC91 - Manual (Page 26)

When compaction is complete, shut off compactor before lifting it from
the ground.
Do not pound the ground with the compactor.
Do not start in the middle of an un-compacted area. Always start at the
edge, near a solid wall, bank, or a previously compacted area.
Compacting Clay Materials
Clay type materials have a different composition and will not transmit
vibration as well as granular materials; therefore, it is necessary to
decrease the lift height and hold the compactor position for 15 seconds in
each spot. Two passes are usually sufficient.
Sheet or Pile Driving
Compactors are effective in driving timber sheeting, steel sheet piles, 'H'
or 'I' beams, and they drive into most soils including fine sand and rocky
material. Best results are achieved by keeping the compactor base 90
O to
the pile and use down-force and vibration to hammer the material. If you
come across excessive resistance, lift the compactor slightly and let it
'bounce' on the pile for a hammering effect. Do not use the compactor to
extract pilings.
Cold Weather Operation
Oils for use in cold weather operation should have a viscosity not
exceeding 7500 SSU at the minimum start up temperature. And the ambi-
ent temperature should be at least 20
o
F above the pour point of the oil.
Start with a gradual warm-up until the oil reaches a reasonably fluid
state.

Bolt Loctite
Requirements
At the end of each shift check the following:
Check rubber isolators for cracks. Replace as necessary.
Check the mounting pins and bushings for proper fit to the carrier. Check
that the pin locks are in place and secure.
Check that all hose connections are tight and there are no leaks.
If your compactor is equipped with a swivel mount, grease this connec-
tion with 5 shots dependent on the amount of compactor use.
Always use standard EP2 grease.
Check that all bolts are tight. If necessary, remove the bolt and install
using Loctite and tighten to the specified torque.
• Red Loctite: motor and eccentric housing bolts
• Blue Loctite: rubber isolator bolts and all others
