1. Introduction
We congratulate you on this purchase. Be sure to read and understand this user manual before using
the tool. This user manual covers the basic aspects for the safe use and operation of this equipment.
First of all check that your equipment is complete and undamaged. Notify your Holmatro dealer
immediately if the equipment is damaged or incomplete, and do not use the equipment.
This equipment is designed for use by professional, fully trained fire and rescue personnel.
This is a double-acting hydraulic tool designed to be driven only by a Holmatro hydraulic pump. The
entire system operates with mineral oil hydraulic fluid to an allowable pressure of 720 bar. There are
two versions of the tool available.
1.) A Twin-line version with a separate input pressure line and return line.
2.) A Core™ technology version with the input pressure line contained inside the return line
Follow these instructions to ensure your safety and to keep your equipment in good condition.

6. Operation
The oil from the hydraulic pump is supplied to the unit via high-pressure hoses. The oil returns at
atmospheric pressure to the pump if the dead-man's handle is in the neutral position.
Fig. 1. Control handle label.
Oil is admitted under the piston if the dead-man's handle is in the “open” position. The arms will
then open. The oil above the piston flows back to the pump.
Oil is admitted above the piston if the dead-man's handle is in the “close” position. The arms will
close. The oil under the piston flows back to the pump.
The dead-man's handle always returns to the neutral position when released.
TWIN-LINE TOOLS
The hydraulic system in the unit is provided with a safety valve. This safety valve prevents
excessive pressure in the tool if the return line to the pump is blocked or disconnected. Never
change the setting of this safety valve. Oil will discharge from the rear of the tool if the return hose
becomes blocked or disconnected while the pump pressure relief valve is in
“PRESSURE”/”OPERATION” position. If this happens, first switch the pump pressure relief valve
to the “NEUTRAL” position, and then re-connect the return hose of the tool.
CORE™ TOOLS
The hydraulic system in the unit is provided with a safety valve. This safety valve prevents
excessive pressure in the tool if the return line to the pump is blocked. Never change the setting of
this safety valve. Oil will discharge from the rear of the tool if the return hose becomes blocked
while the pump is running. If this happens, first switch the pump engine/motor to OFF and
disconnect the hose. Then connect a new hose.
When Holmatro valve blocks are mounted on your Holmatro power unit, the manual
operated release valve is no longer needed. As soon as the hose is connected, oil is flowing through
the hose’s inner shell and returning back to the tank of the pump through the hose’s outer shell.
When a rescue tool with the adaptor installed has been connected to the hose, oil will flow
into the tool. To change from one rescue tool to another, the user simply disconnects the rescue tool
from the hose and connects the alternate rescue tool to the hose. Oil always flows from the female
coupler into the male coupler for Holmatro systems.

carrying handle.
Lift the deadman’s handle slightly to take the weight off the locking mechanism.
Push the mechanical lock (A) to the left or the right to release the locking mechanism.
Lift up the mechanical plunger (B) to the desired height.
Release the mechanical lock. Make sure that the mechanical plunger is locked in one of

Retract the mechanical plunger.
Hold the tool with one hand on the deadman’s handle, and the other hand on the
carrying handle.
Operate the deadman’s handle to retract the hydraulic plunger.
Lift the deadman’s handle slightly to take the weight off the locking mechanism.
Push the mechanical lock (A) to the left or the right to release the locking mechanism.
Lower the mechanical plunger (B) to the desired height.
Release the mechanical lock. Make sure that the mechanical plunger is locked in one of
the grooves.
Rotate the carrying handle.
The carrying handle can be rotated around the cylinder between two lock positions.
Never set the carrying handle in an unlocked
position. The mechanical plunger may extend out
of the cylinder if the locking mechanism is not
engaged.
Push the lock button (A) to release the locking mechanism.
Rotate the carrying handle to the next locking position. The locking positions are
located 180°apart. The carrying handle should never be left in the unlocked position.

7. Use
7.1 Initial use (first time only)
* Check the equipment for damage. Do not use the equipment if it is not in good
condition. Notify your dealer.
* Check whether the guarantee registration card has been supplied and filled in.

7.2.1 Coupling
The unit is equipped with different quick-action couplings, i.e. "male" and "female".
For Twin-line tools, never connect or
disconnect the quick-action coupling when
the pump relief valve is set to “PRESSURE”/
“OPERATION”. Set the pump relief valve to
its "NEUTRAL" position before coupling or
uncoupling hoses and/or tools.
To couple the hoses using the flat face coupler:
1. Remove the dust caps from both the male and female couplers.
2. Insert the male coupler into the female coupler and push.
3. The coupler’s locking ring (A) will move forward to show the coupler is locked.
4. Check to make sure the connection is made by pulling on the two couplers.
To uncouple the hoses using the flat face coupler:
1. Push the hose coupler gently forward into the tool/pump coupler.
2. Turn the locking ring (A) of the coupler ¼ turn counterclockwise when holding it
in your hand pointing away from you (direction of large arrow on coupler) and
pull back on the locking ring (direction of small arrow on coupler). l
3. Remove the male coupler from the female coupler if it has not released
completely.
4. Make sure you put the dust caps back onto the couplers when not in use. This is
an important step to keep dirt and foreign objects from getting into the coupler.
Twin-line female coupler
Core™ female coupler
Clean the female coupler by removing any dirt, oil, etc. with a clean dry rag. To ensure the automatic
locking capability of the coupler, the couplers and dust caps should be checked periodically and
cleaned by following the simple steps below:
1. Rinse the coupler and dust cap with lukewarm water and a soft soap solution.
2. When the coupling is dry and free from water, lubricate the flat end of the coupling (B) with
Holmatro recommended hydraulic oil or by spraying WD-40 onto the end.
3. Lubricate the locking sleeve by spraying WD-40 carefully in the area (C) between the back
part and the locking sleeve.
4. Connect the nipple into the coupling and see if the locking sleeve easily turns itself to the lock
position. Check by pulling the locking sleeve straight back. The nipple should not disconnect.
5. To disconnect the nipple, turn the locking sleeve and pull it backward.
6. Repeat steps 4 and 5 a few times to assist internal lubrication of the locking sleeve.
