IMPORTANT NOTICE!
WARNING
: When filling
gearbox oil, never use
90W gear oil or vibro will
overheat. If you cannot read
the level then do not operate
the machine. Remove the
sight glass (See Image
J for location reference)
Spray WD40 to clean the
glass, then reinstall the sight
glass using O-Ring lube. Do
not overfill or the vibro will
overheat.
If gearbox sight glass level
increases, it can indicated
there is a bad motor shaft
seal. Results are hydraulic
oil entering the gearbox.
NOTE:
When mounting a new clamp, check machined surfaces on the bottom of the hammer and on top of the clamp with a straight
edge. Clean each mounting hole with a bottom tap and WD40. Make sure the surface is clean and flat. Torque down using a hydraulic
torque multiplier. Do not drive piles if any clamp mounting bolt are missing. If the clamp attachment falls off, it is due to bolts not being
properly torqued.
