TROUBLESHOOTING GUIDE (continued…)
Problem
Possible Cause
Solution
9. Pump builds to full
pressure, but tool does
not advance / operate.
a. Advance or Return flow line to tool
restricted or blocked.
Check couplers for full engagement.
b. Required torque exceeds tool
capacity.
Make sure the tool is correctly rated for the
application.
10. Erratic tool
movement.
a. Leakage from pump or valve
internal components.
Contact your local Hi-Force office / distributor.
b. Internal leak, due to damaged/worn
seals or valves.
Contact your local Hi-Force office / distributor.
c. Oil level too low.
Check unit for visible leaks. Add oil as per
section 5.2.
d. Air in the hydraulic system.
Bleed air from the system. (
See section 5.7
)
e. Tool piston binding.
Contact your local Hi-Force office / distributor.
11. Tool stalls under load
or before maximum
torque is reached.
a. Control Valve damaged.
Contact your local Hi-Force office / distributor.
b. Seal damage / wear or internal
damage.
Contact your local Hi-Force office / distributor.
12. Noisy Operation
a. Air trapped in the hydraulic system. Bleed air from the system. (
See section 5.7)
b. Air leaking into the hydraulic
system.
Visually inspect all areas where air might leak
into the hydraulic system.
c. Oil level too low.
Check unit for visible leaks. Add oil as per
section 5.2.
Auto Pressure Dump Feature & Manual Override
Always stop the pump buy pressing the “STOP” button (21) or (10) before attempting to connect or
disconnect a hose/s. Attempting to disconnect hoses while the pump is running is difficult and can result in
leakage or injury.
When the pump is stopped, the solenoid valve activates briefly to release any pressure trapped in the
system, making disconnections easier.
In the event of a power failure, this automatic pressure dump feature will not function and the pressure will
need to be release manually.
To do this, press the manual override button (4) located on top of the solenoid valve, to release trapped
pressure in the oil and allow easy hose disconnection.
