8.0 Troubleshooting
TROUBLESHOOTING GUIDE
Possible Cause
a. Air supply not connected.
b. Low air pressure / volume.
c. Air supply restricted
d. Air motor is damaged, seized or
worn.
a. Low air pressure / volume.
b. Inadequately lubricated air supply.
a. Oil level too low
b. External oil leak in the system.
c. insufficient air pressure causing
pump to stall
d. high pressure/pressure release
valve not closed
e. tube connections loose in the
system.
f1. hydraulic check valves have
developed a leak.
f2. fluid bleeding past the seals in the
hydraulic tensioners.
a. pump appears to be short stroking
and running too fast without
pumping correctly
b. excessive amount of oil or water is
coming through the pump air
exhaust
a. Air leaking into the hydraulic
system.
Operating Instruction Manual:
OM-AHP-BTU-01
Solution
Connect air supply.
check the regulated air pressure is available
via the air pressure gauge (19) mounted on
the FRL unit.
check the air stop/control (5) valve is in the
open position [2b].
Contact your local Hi-Force office / distributor.
Check air supply, including regulator setting
and the size of the connecting hoses to
ensure the correct airflow / pressure
requirements are met. (See section 5.5-5.6)
Check air lubricator levels and make sure the
oil drip rate is correct. (See section 5.7)
Check unit for visible leaks. Add oil as per
section 5.2.
Contact your local Hi-Force office / distributor.
Check air supply, including regulator setting
and the size of the connecting hoses to
ensure the correct airflow / pressure
requirements are met. (See section 5.5-5.6)
close high pressure/pressure release valve (6)
to build up pressure.
check tub connections in the system and
rectify.
Contact your local Hi-Force office / distributor
usually, indicates the air check assembly is
not working as it should be. Contact your local
Hi-Force office/distributor
1. the lubricating unit on the air supply is
delivering too much oil. Adjust accordingly
(see section 5.7)
2. the filtering unit in the air supply is not
functioning correctly. The bowl should be
cleaned periodically to ensure delivery of
clean air to the pump.
3. the fluid being pumped may be leaking past
the seals in the hydraulic cylinder into the air
motor. The unit will require inspection and
repair.
Visually inspect all areas where air might leak
into the hydraulic system.
