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.

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.
* Check whether the accessories are correctly mounted.
7.2 Preparation for use
* Check the operation of the dead-man's handle (return to neutral position).

10
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.

11
7.2.2 Use
Turning the dead-man's handle clockwise has the same result in all Holmatro
equipment (from 01.01.95): the functional parts are opened. The functional parts are
closed by turning counter-clockwise. As soon as the dead-man's handle is released it
automatically returns to its neutral position and the unit stops operating immediately.
7.2.3 Spreading
Ensure that the original crossheads are
attached correctly.
The pistons are extended by turning the
dead-man's handle clockwise and objects can be pushed apart. The pump
automatically supplies the required pressure as soon as the cross heads experience any
resistance.
Prevent sharp protrusions from touching
the piston during spreading. Damage leads
to leakage through the seal.
Prevent the cross heads from sliding from
the load. Use the optional ram support for
weakened car bodies (see accessories
section). Use only original Holmatro
accessories and attach them correctly.
7.2.4 Shutting down
On completion of the work retract the pistons back into the cylinders. Check that the
pump relief valve is in its "neutral" position before uncoupling. Remove any dirt from
the couplings and the dust caps to prevent penetration into the hydraulic system. Take
the dust caps apart and place them on the tool’s couplings.
When the retracting movement stops,
spread the pistons again over a small
distance of approx. 1/4 inch to relieve any
pressure in the tool and store the tool in
that condition.
7.2.5 Cleaning and storage
Clean the unit and any accessories used before storage.
* Clean all quick-action couplings and dust caps. Ensure that the dust caps are
clean and installed.
* Check the tool for external damage and/or oil leakage.
* Check the operation of the dead-man's handle.
* Dry the unit if it has been used in wet conditions. Lightly oil the steel parts.
* Clean the tool with a mild soap solution and dry thoroughly.

12
7.3 Important additional user information
The hydraulic hoses belonging to the hydraulic
system need attention. Observe the following
points:
1. Do not use hoses without proper anti-kink devices and prevent kinking behind the
attachment.
2. Prevent kinking of the hoses and never bend the hoses beyond their minimum bending
radius
(89 mm) (3 ½ in).
3. Do not pull the hoses to move tools or pumps.
4. Prevent twisting of the hose.
5. Do not use the hoses to keep the equipment in position and especially not if the hoses
are pressurized.
6. Do not store hoses with the ends coupled together.
