Troubleshooting
Problem
Cause
Solution
Core drill will not operate
Core drill not connected properly
Check the performance and connection of
the power source. Make sure that the
return line coupling is completely fitted with
no clearance
Oil flow and/or pressure too low
Check the power source and ensure that
the flow and pressure are according to the
technical specifications
Core drill runs at low speed
Oil flow and/or pressure too low
As above
Contaminated hydraulic system
Clean system
Internal leakage
Carefully check the O-ring seals in the
trigger valve bushing and replace damaged
ones
Core drill runs without pushing the trigger
Un-tightened trigger valve bushing
Tighten trigger valve bushing properly
O-ring failure
Replace the O-ring at the bottom of the
trigger valve bushing hole
Check valve spring broken
Replace spring
Trigger lever stuck
Flow too high
Check the power source and ensure that
the flow and pressure are according to the
technical specifications - and that the
connections are correct
Improper pressure/return line connection
As above
Back pressure too high
As above
Impurities
Check trigger valve/reversing valve for
seizing
Trigger lever cannot be released
Trigger lever blocked in locked position
Readjust the flat spring through the two
screws on the motor housing
System overheats
Flow too high
Reduce the flow from the power source. If
necessary, use a flow divider to control the
flow
Insufficient cooling
Use a power source with higher cooling
capacity or add an additional oil cooler in
the return line
