SWi20/25TE TOOL FUNCTION
HYDRAULIC TOOL OPERATION
The SWi20/25TE Spreading Wedge uses a hydraulic
cylinder to advance the wedge and spread the jaws.
The hydraulic pressure is applied using an external hand
pump, enabling accurate control of the force applied.
HAND PUMP OPERATION
Consult the Instruction Manual for the Equalizer HP Hand-
Pump supplied in the kit.
ACTUATING THE SWi20/25TE
Follow the SWi Spreading Wedge Tool Operation
instructions, using the following instructions to actuate
the SWi20/25TE tool in particular:
When the Hand-Pump release valve is closed, pumping
the Hand-Pump handle will advance the cylinder and
spread the jaws.
When using multiple tools, ensure that the spread of all
tools correspond to keep the spreading force balanced.
The Maxi-kit includes a twin-port hand pump which can
be used to actuate two tools simultaneously.
RETRACTING THE SWi20/25TE
Opening the release valve will depressurise the cylinder
and cause it to retract under the force of its internal
spring. The handle does not need to be pumped to retract
the tool.
When using multiple tools, exercise caution while retracting
to keep the spreading force balanced as the gap is closed.
AIR-LOCK RELIEF
If full pressure is not achieved an air-lock may be present
in the hydraulic system. The following procedure can be
executed to relieve any air-locks.
Connect the hand pump to the tool with the hydraulic
hose. Close the release valve on the pump, and prime the
pump until the hydraulic cylinder is fully extended and a
small pressure is achieved.

SPREADING WEDGE
The SWi20/25TE Spreading Wedge uses an external
hydraulic pump to drive the cylinder to advance the wedge
and spread the jaws.

SWi20/25TE TOOL CAPABILITIES
SPREADING FORCE
With 700bar (10,000psi) of hydraulic pressure applied,
the tool can apply 20T (200kN) spreading force on the 1st
step, up to 24T (240kN) spreading force on the 4th step.
SPREADING GAP (SEE SECTION 3.9)
Using only the 1st step, the tool can spread from 6.0mm
to 40.0mm (0.24” - 1.6”).
Using all 4 steps, but without the stepped blocks, the tool
can spread from 6.0mm to 87.5mm (0.24” - 3.4”).
Using both steps on the stepped blocks, the tool can
spread 48.5mm – 103.5mm (1.9” - 4.1”).
