Operation

Switch on/off

By pressing the button (1) the LEVA

Hydraulic pump is turned on and the

tool piston extends.

The return stroke is triggered

when released.

The Hydraulic Pump

switches off by pressing

the button (2)

4.1

Torque setting

Check the hose connections of the Hydraulic

Wrench / Hydraulic Pump.

See also point 9, page 10, connection diagram.

Then connect the pump to the mains.

The torque of hydraulic wrenches is proportional to the pres-

sure. The required operating pressure for the corresponding

torque is now determined from the torque table of the hy-

draulic wrench and set on the LEVA Hydraulic Pump.

Do not place the hydraulic wrench on the bolt

or nut yet!

Setting steps:

Press and hold the white button (1) on the remote

control. The piston of the hydraulic wrench extends.

After reaching the end position, the system pressure

is adjusted accordingly by turning the adjusting knob

on the pressure adjusting valve (3) (pressure increase

clockwise / pressure decrease counter clockwise).

The current operating pressure is displayed on the

pressure gauge (2). Release the white button on the

remote control (1), the piston of the hydraulic wrench

then moves back.

Checking the setting:

Press the white button (1) again to fully extend the

torque wrench piston. Hold until the necessary pres-

sure is reached.

After checking the pressure gauge, readjust the pres-

sure with the adjusting knob if necessary.

As soon as the required pressure is set, the setting is

secured against twisting with the wing nut (3.1).

Operation with the remote control

When tightening or loosening a bolted connection,

the instructions for use of the hydraulic wrench

must always be given equal priority!

Observe the technical information regarding oil

temperature, point 7, page 9.

Place the hydraulic wrench on the bolt connection.

By pressing and releasing the white button (1) you

can rotate the output. A corresponding torque is the

result. Press button (1) repeatedly until the hydraulic

wrench stops rotating and the set operating pressure

or torque has been reached. Carry out a visual inspec-

tion on the pressure gauge.

Tip:

Press the button (1) once or twice to ensure that the

applied torque is transferred to the bolt connection

and that the hydraulic wrench does not just stop at

the end stop of the hydraulic piston.

Observe the pressure gauge display (2, Fig. 3) on the

hydraulic pump ensure that the previously set operat-

ing pressure has been reached.

(When loosening a bolt connection, this process is

repeated just as often until the bolt connection has

completely loosened, see also point. 4.3)

The LEVA Hydraulic Pump switches off by pressing the

black button (2).
