9. Troubleshooting
PROBLEM CAUSE SOLUTION
Valve is leaking
Loose/cracked fittings Tighten/replace fittings
Worn hose Replace hose
Valve spools are worn Replace valve
Hydraulic cylinder
leaking
Worn seal Replace seal
Loose cylinder cap
Tighten cap bolts and monitor leak. If leak persists,
replace cylinder seal
Mast cylinder is
leaking Head nut is loose Tighten nut
Worn seal Replace seal
Mast tilts too
slowly
Low system flow/pres-
sure
Increase PTO speed or hydraulic flow from tractor
Hydraulic oil level is low Check oil level and add oil if required
Hydraulic line blocked or
kinked 1) Suction blocked hose(s)
2) Replace kinked hose(s)
Mechanical binding
Check for any obstructions to mast movement,
including hoses, lock bars.
Hammer rises too
quickly Excessive system flow/
pressure
Decrease PTO speed or hydraulic flow from tractor
Hammer rises too
slowly
or
Hammer raises
part way, sticks,
and stops
Low system flow/pres-
sure
Increase PTO speed or hydraulic flow from tractor
Oil too hot
Tank level low, wrong oil used, oil is contaminated,
or ambient temperature is high for rate of operation.
Hydraulic line blocked or
kinked 1) Suction blocked hose
2) Replace kinked hose
Mechanical binding
Check for any cause of binding or obstruction
between mast parts. Check mast assembly for mis-
alignment, bent mast, broken welds, loose or miss-
ing bolts, misaligned components.
Excessive ballast Reduce ballast weight to 280 lbs or less
Hammer drops too
slowly
Mechanical binding
Check for any obstructions to mast movement,
including hoses, lock bars.
Return line restricted
(blocked, kinked, or oth-
erwise impeded) Suction out blocked lines, and replace kinked hoses
or non-Wheatheart connectors that might obstruct
flow.
Hammer drops
quickly, but does
not deliver enough
force to drive post
Ballast too light Increase ballast weight, but do not exceed 280 lbs.
Hidden obstruction in soil
Large tree roots or rocks can impede or stop post
from being driven. Reposition post and attempt
again.
Soil too hard, post too
large
It is possible that some combinations of very hard
soils combined with large post diameters will make
pounding a post slow or impossible.
Solution: pre-drill post holes or cut a point on the end
of the post.
