Troubleshooting-
[cont’d]
Condition Cause
Corrective
Action
Oil leakage from body,
accumulator or front
head
Damaged or worn seals
Stop Breaker operation immediately and replace seals
Ruptured accumulator
membrane
Stop Breaker operation immediately and service
accumulator
Broken Through Bolt
Stop Breaker operation immediately and replace
Tool
Excessive / uneven
wear
Excessive galling of tool shank
or bushings
Check breaker tool is receiving sufficient lubrication
Increase lubrication frequency. Use Allied Chisel
Paste
Maintain right angle to work surface. Refer to
operating technique Section 6.
Excessive wear on tip
Reduce advance, Limit cycle time. Refer to operating
technique Section 6.
Uneven wear on tip
Maintain right angle to work surface. Refer to
operating technique Section 6.
Tool breakage
Excessive tool length
Use shorter length tool
Tool driven into material and
becomes stuck
Limit tool penetration. Refer to operating technique
Section 6.
Bending force exceeds material
strength
Never pry with tool. Refer to operating technique
Section 6.
Operator technique to adopt correct working angle.
Maintain 90° angle to work surface. Refer to operating
technique Section 6.
Material strength is weakened if
surface is damaged from
galling, deep gouge or
corrosion.
Operator technique to adopt correct working angle.
Maintain right angle to work surface. Refer to
operating technique Section 6. Check tool is receiving
sufficient lubrication. Increase lubrication frequency.
Use grease that is approved for this application such
as a premium high temperature and extreme pressure
type grease. Allied Chisel Paste is specifically
formulated for this application. Store indoors. Coat
with grease to protect from moisture.
The Breaker is not self-powered. Its performance
level is affected by a hydraulic system that is not
operating to specification.
All hydraulic breakers are designed to provide
optimum performance with reliable service life at a
specific oil pressure. The correct pressure must be
maintained for proper functioning, optimal efficiency
and reliable service.
If the Breaker is working incorrectly, first check that
the mode switch is positioned correctly for operating a
breaker. Next, check that the shut off valves are fully
open.
If there is no improvement in the breaker’s
performance, conduct a thorough evaluation of the
carrier’s hydraulic circuit. Measure oil pressures at
the supply [IN] and return [OUT].
Further testing may be necessary and will require the
use a flow meter. Be sure to include the breaker’s
supply and return hoses when conducting a flow test,
as they may be faulty, e.g. collapsed hose. Use the
flow meter to measure oil delivery from the pump and
to verify the cracking pressure of the relief valve.
