7.0 Care and Maintenance
7.1 Preventative Maintenance Checks & Services
All hydraulic breakers require regular inspection and
maintenance. The aim of inspection and maintenance
programs is to preserve equipment reliability by
replacing worn components before they reach the
point of failure.
The following includes the minimum requirement for
maintaining the equipment in safe operating
condition. Service intervals apply only to normal
applications. In extreme operating conditions or
applications such as underwater, tunneling, scaling,
foundry cleaning, etc., the breaker will require
inspections on more frequent intervals.
Daily Pre-operation Walk-around Inspection
 Lubricate breaker tool
 Check breaker tool is properly engaged in front
head
 Check level and operation of automatic lube
system - If equipped
 Check for loose or missing fasteners
 Check for fluid leaks at tubes, hoses, connections
and seals
 Ensure hoses are not rubbing and tubes are
secured tightly in clamps
 Ensure breaker is properly engaged with carrier.
Check mounting pins and ensure pin keepers are
secure

Check housing and mounting bracket for wear
and cracks
 Look for signs of contact between breaker and
housing caused by excessive movement
Every 2 Hours (While in use – Service Hours)
 Lubricate breaker tool or sooner if the tool
appears dry
 Check breaker tool is properly engaged in front
head
During Shift (While breaker is in use)
 Actively monitor efficiency and evenness of
operation. Look and listen for any interruptions
from normal operation
 Monitor hydraulic oil temperature. Keep within the
required operating range
 Be alert to fluid leaks
Every 50 Hours or Weekly
 Measure gap between breaker tool and bushing
Every 100 Hours or 2 Weeks
Remove breaker tool from front head
 Check retainer slot area for burring
 Inspect impact surface for uneven wear, cracks
or chips
 Inspect retainers for wear, cracks or chips
 Inspect impact surface of piston for uneven wear,
cracks or chips
 Inspect thrust ring for evenness of wear, cracks
or chips
Every 250 Hours or 3 Months (Or As Required)
 Measure hydraulic oil pressures and confirm all
are within required range
 Should repairs or changes be made to the
hydraulic system, the oil flow and pressure must
be re-tested.
At Rebuild
 Replace all seals. Replace all worn components
 Replace accumulator membrane and charge
accumulator
After Rebuild – Before Use
 Test quality of hydraulic oil
 Service hydraulic oil filters
 Test hydraulic circuit with flow meter and
pressure gages.
