Operation
There are four holes in the bases of the HSBL
punching tool 120. Use these holes to fasten
the tool to a work bench.
Slide the 2420 working cylinder with the
cylinder spars on to the punch’s pressure
plate and fasten with the fixing bolts.
Connect the working cylinder to the hydraulic
unit using the rapid-action coupling and the
plug (see page 2).
To deaerate the cylinder carry out a few idle
runs.
The hydraulic unit should be on a higher level
than the working cylinder when deaerating.
