7.0 Care and Maintenance
7.1 Inspection & Maintenance Schedule
All hydraulic breakers require regularly scheduled
inspections and service. The aim of these inspections
is to spot problems in their early stages, before they
worsen into serious damage and costly repairs. In
addition to monitoring parts for wear, scheduled
inspections are useful in spotting trends and
identifying potential problem areas.
The following service interval applies to normal
applications. Breakers working in severe operating
conditions or special applications such as
underwater, tunneling, scaling, foundry cleaning, etc.,
may require more frequent service.
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.
