Screw the locking collar back into the tool body ensuring that the punch is

correctly centred in the collar and that it goes fully into the recess in the piston

of the tool. Tighten the locking collar using the tommy bar but do not use

excessive force.

Connect a hydraulic pump to the tool using a high pressure hose (HHP30

requires 1 hose and the HHP50 requires 2 hoses) of convenient length. Do not

use any tools to tighten the sleeve on the coupler. Hand tight is sufficient.

Operate the pump slowly to advance the punch and check that it is correctly

centred to the die. Retract the punch by operating the pump valve to allow oil to

flow back to the reservoir. (Refer to pump instructions for more details) Repeat

this operation several times with the punch lower than the pump to ensure there

is no air in the system and familiarise yourself with the operation.

The hydraulic hole punch is now ready to use.

OPERATION

Mark the required position of the hole on the steel plate. For accurate location

use a centre punch or small drill to mark the exact centre of the hole.

Move the hole punch into position with the aid of the handle and the C shaped

section of the tool body. Do not use the hose or coupler for lifting and

positioning the tool.

Advance the punch slowly until it is just touching the steel plate and adjust the

position of the tool if required.

Operate the pump to advance the punch. Stop the pump as soon as the punch

breaks cleanly through the steel plate.

Retract the punch to by allowing oil to return to the pump reservoir and remove

the tool from the steel plate.

Ensure that the blank from the punched hole is not jammed inside the die, and

check there is no damage to the punch or die. The tool is now ready for the next

operation.

MAINTENANCE

Inspect all parts for damage after very use and replace as required.

Remove all debris from around anvil after every use. If the tool is to be stored

for a period of time, coat punches, dies and locking collar with moisture

repellent spray such as WD40 or oil. Do not leave the tool exposed to the

environment.
