6.0 OPERATION
6.1 Oil Level
Check the oil level of pump and add oil if necessary (See
Installation section, chap. 5.6).
6.2 Venting Pump
Make sure the pump reservoir is vented (See Installation
section, chap. 5.4).
6.3 Treadle Operation
See pic. 6.
a) To Advance Cylinder: Depress the "PRESSURE" end
of treadle and the pump will start to pump hydraulic oil
to the system.
b) To Hold The Cylinder Position: The pump will stop and
hold pressure when the treadle is in the free/neutral
position (treadle is not depressed in either "PRESSU-
RE" or "RELEASE" positions.)
c) To Retract Cylinder: Depress the "RELEASE" end of
the treadle to retract cylinder. To stop the cylinder from
retracting, release the treadle and return it to the hold
position.

PROBLEM
1)Pump will not start
2) Motor stalls under load
3) Pump fails to build pressure
4) Pump builds less than full pressure
5) Pump builds pressure, but load does not move
6) Cylinder drifts back on its own
7) Cylinder will not return
8) Low oil fl ow rate
* 85 psi (5,86 Bar) air pressure required to obtain 10,000 psi (700 Bar) hydraulic pressure.

Inlet fi lter plugged, insuffi cient air fl ow
External leak in system
Internal leak in pump
Internal leak in system component
Low oil level
Low air pressure*
Internal relief valve set low
External system leak
Internal leak in system component

A) Single-acting type
Return fl ow or coupler restricted/blocked
No load on a „load return" cylinder
Return spring broken on cylinder
Release Valve Malfunction
B) Double-acting type
Return fl ow or coupler restricted/blocked
Valve malfunction
Reservoir not vented
Inadequate air supply
Dirty air fi lter
Clogged inlet fi lter
7.4 Cleaning The Air Inlet Filter
Remove the swivel air connector by removing the two
cap screws and pulling air fi lter out of cavity. Using an
air nozzle blow debris off fi lter. (Always use proper eye
protection). Re-install fi lter and swivel connector. Torque
cap screws to 16-18 in.lbs [1,8-2,0 Nm].

TROUBLESHOOTING
Only qualifi ed hydraulic technicians should service the
pump or system components. A system failure may or
may not be the result of a pump malfunction. To determi-
ne the cause of the problem, the complete system must
be included in any diagnostic procedure.
The following information is intended to be used only as
an aid in determining if a problem exists. DO NOT disas-
semble the pump. For repair service, contact the Auto-
rized KLAUKE Service-Center in your area.
