HHP30 AND HHP50 HYDRAULIC HOLE PUNCH OPERATING AND
SAFETY INSTRUCTIONS
INSPECTION UPON RECEIPT OF GOODS.
On initial receipt of goods visually check for transit damage. If found contact the
carrier immediately.
DESCRIPTION
The Hi-force HHP series hydraulic hole puncher range offers achoice of two
models HHP30 and HHP50 (Refer to figure 1for model specifications).The
HHP30 hole punch is a single acting spring return punching tool with a
maximum punch force of 26 tonnes. It is capable of punching holes up to
20.5mm in diameter in mild steel plates up to 10mm thick. The HHP50
hole punch is a double acting punching tool with a maximum punch force
of 44 tonnes. It is capable of punching holes up to 25.5mm in diameter in
mild steel plates up to 15mm thick. The maximum throat depth for HHP30 is
65mm and 75mm for HHP50. This is the maximum distance from the edge of
the plate to the centre of the hole to be punched. The punch can be operated by
means of a hand pump or power driven pump.

SAFETY.
Read these instructions and safety warnings fully. Failure to do so could result
in Personal injury or equipment damage.
WARNING: Wear suitable personal protection equipment when operating
hydraulic equipment. Safety glasses are essential.
DANGER: Keep all body parts away from punch and work piece during
operation.
WARNING: Do not exceed rated pressure of tool (700 bar maximum working
pressure). Do not connect to a pump with a higher rated pressure.
WARNING: Ensure that all components in the system are rated for 700 bar.
CAUTION: Use a pressure gauge whenever possible.
DANGER: Do not handle pressurised hoses. Oil escaping under pressure from
a ruptured hose can penetrate the skin. If oil is injected under the skin it is a
serious medical emergency. See a doctor immediately.
CAUTION: Avoid damaging hydraulic hose. Always route hoses to ensure they
are free from sharp bends and kinks.
CAUTION: Always disconnect the punch from the pump when changing
punches and dies.

PREPARATION FOR USE
Refer to figure 2 for identification of parts.
Select the size of punch required based on the hole size that needs to be made
(Refer to Figure 1 for punch / die sizes).
Slacken the die retaining screw in the side of the anvil, and fit the die into the
recess with the identification spot upwards. Tighten the die retaining screw.
Unscrew and remove the locking collar using the tommy bar provided. Fit the
punch into the locking collar in the direction shown in figure 3.
Ensure that the identification spot on the punch is the same colour as that on
the die.

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.
