Troubleshooting Guide
[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 Section
6.0
Excessive wear on tip
Reduce advance, Limit cycle time. Refer to Section
6.0
Uneven wear on tip
Maintain right angle to work surface. Refer to Section
6.0
Tool breakage
Excessive tool length
Use shorter length tool
Tool driven into material and
becomes stuck
Limit tool penetration. Refer to Section 6.0
Bending force exceeds material
strength
Do not pry with tool. Refer to Section 6.0
Operator technique to adopt correct working angle.
Maintain right angle to work surface. Refer to Section
6.0
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 Section
6.0. Check breaker tool is receiving sufficient
lubrication. Increase lubrication frequency. Only 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
delivering to specification.
All hydraulic breakers are designed for optimum
performance with reliable service life when operated
within the specified parameters. If Breaker operation
is abnormal, first check that the carrier's mode switch
is set in the correct position for operating a breaker.
Next, check that the shut off valves are fully open.
If no improvement is seen in the breaker’s
performance, conduct a series of tests to evaluate the
output of the carrier’s hydraulic circuit. Measure oil
pressures at the supply [IN] and return [OUT].
Use a flow meter to test oil delivery of the hydraulic
circuit. 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. The flow meter is
also used to verify normal operation of the relief valve
and the correct setting of the cracking pressure.
