Storage
For the best results, always store equipment in
a dry, protected location. Leaving equipment
unprotected will shorten the service life of the
Post Driver.
1
.
Before storing, remove debris and clean
the entire unit using compressed air or a
pressure washer.
2
.
Inspect the Shaver Post Driver. Replace
any worn or damaged parts before using
the Post Driver again.
• Check all bolted connections. Ensure
that fasteners are tight, and all pins are
secured in place.
• Inspect the frame for structural fractures.
• Make sure all warning decals are in place
and legible.
• Make sure the rubber debris guard is in
place and in good condition.
• Check the hydraulic cylinder(s) for signs
of seal damage or excessive wear.
• Inspect all hydraulic hoses and fittings for
leaks or signs of wear.
3
.
After cleaning, lightly lubricate the guide
blocks with clean engine oil. Do not apply
grease, as this will retain grit and cause
excessive wear.
4
.
Clean and lubricate the hydraulic control
valve safety stop linkage. Make sure the
return spring and cotter pins are in good
condition.
5
.
Apply a light coating of clean grease to all
exposed hydraulic cylinder shafts to help
prevent rust.
