Hydraulic Pump - Gilson TS-2 Operating Manual

Gilson Company, Inc.
m. To bleed the air out of the hydraulic system;
• Loosen the connections between the hoses
and the cylinders by unscrewing the swivel
connections slightly.
• Pump up the hydraulic system just until oil
appears at the loosened connections.
• Retighten the swivel connections.
n. If the fittings leak, use hydraulic joint compound
to create a seal between each leaky fitting and
the pump or cylinder to which it is attached.
o. Reinstall covers. Do not plug in or try to operate
the Testing Screen without all covers installed.

5.5.3. Hydraulic pump

The hydraulic pump is a low-pressure pump with a cast
aluminum body. If your pump leaks or malfunctions,
especially if the machine is old or heavily-used, we
strongly recommend that you return it to the factory
for repair (a three to five day process), or purchase a
new pump. Call for instructions.

It is sometimes possible to repair pumps in the field by
replacing parts. We DO NOT recommend field repair
unless you have experience in working with hydrau-
lics. Refer to the guidelines below and the diagrams
and parts list at the back of this manual. The various
springs in the pump are NOT interchangeable. When
working with the hydraulic pump, take care NOT to
score surfaces where seals must be maintained.
WArninG!: Disconnect the machine from its power
source and lock out the connection prior to perform-
ing maintenance and/or repairs.
foLLoW tHeSe GenerAL inStrUCtionS when
repairing the pump yourself:
a. Unplug or otherwise disconnect the Testing Screen
from its power source, and lock out the connection.
b. Drain the pump, following the instructions in Section
5.5.2. ALWAYS observe the position of the internal
pump cover before you remove it. Its vent is slightly
closer to the front (handle) end of the pump than to
the back. When you remove the cover, set it aside
carefully so that you will know how to reinstall it.
