Safety features
The pump is equipped with a safety valve that limits the
output pressure. The safety valve is set at the factory to
the maximum working pressure.

Installation

General
Always check that hoses, couplings, cylinders and tools,
etc., that are connected to the pump are intended for
use at a working pressure that equals or exceeds the
maximum working pressure of the pump.
Connecting the hydraulic hose
Connect the hydraulic hose with a 3/8"-18 NPTF coupling or use
a Simson quick coupling. Air can accumulate
in the hydraulic system when hoses and tools are connected,
and this can lead to operating problems, see the
heading Bleeding the hydraulic system.
Connecting cylinders/tools
Cylinders or tools can only be connected to the pump
when the system is depressurized. Always make sure that
the release knob is in the open / release position before
connecting.

Operating instruction
Pumping
(Fig. A.3.)
Close the release knob by turning it clockwise.
Releasing
(Fig. A.3.)
• Open the release knob by turning it anti-clockwise.
• To stop releasing the pressure, close the knob (turn
clockwise).
The design of the knob permits controlled release
of the pressure.
NOTE, check that the pump is not overfilled when
releasing a cylinder or tool.
The VS5 special overfilling safety valve can be supplied
as an option. The valve prevents tank over-pressurization
upon releasing

Maintenance

To ensure reliable operation and long life it is important
to carry out maintenance at set intervals. You should always
follow these simple rules:
Always make sure that:
• The pump is cleaned before returning to storage.
• Lubricate moving parts.
• Check that there are no external hydraulic oil leaks.
• Make sure the pump has not suffered any external
damage, as a result of impacts, etc.
Servicing
Checking the oil level
Check the oil level before use. The oil level must always
be measured with the ram/tool in the lowest/retracted
position. For good function, use hydraulic oil equivalent
in quality to ISO VG 10.
(Fig. A.2.)
The filler hole on the hydraulic oil reservoir is also used to
check the level. Position the pump with the pump head
facing down-wards, and remove the filler plug A. The
correct level is when the oil reaches the bottom edge
of the filler hole. Refit the filler plug, tightening it with a
maximum torque of 20 Nm.
Filling with oil
Position the pump with the pump head downwards.
• Remove the oil filler plug.
• Fill with oil, making sure the pump is not overfilled.
• Refit the oil filler plug.
