Preparation for first use

4.1 General
• Check the equipment for completeness and damage. Do not use the equipment if it is damaged;
in that case contact the Holmatro dealer.
• Check the operation of the deadman's handle. The handle must return to the neutral position when
you release it.
• Check the operation of the lock pins.
4.2 Installing the battery for the LED light
See Fig. 4.
The battery for the LED light is placed in the carrying handle. This battery has a working life of ± 6
hours.
• Remove the cover (C) by unscrewing both screws (B).
• Install the battery (A) in the battery holder of the carrying handle.

5 Operation
5.1

System operation

A system is an assembly of a hydraulic pump, hose(s), and one or more tools.
The hydraulic pump is driven by an internal combustion engine, an electric motor, pneumatically or by
hand or foot power. This pump displaces hydraulic oil and is capable of building up pressure. The hose
is for transporting the hydraulic oil between the pump and the tool.
The tool has a hydraulic cylinder containing a piston that can move axially. If the cylinder is pumped full
from the bottom, pressure builds up beneath the piston so that it is pushed to the outside. If the cylinder
is pumped full from the top, the piston is forced back into the cylinder.
The direction of the movement of the cylinder is determined by a control valve, the so-called deadman's
handle. This deadman's handle can be turned to the left or the right, thus determining the direction the
piston moves. In the neutral position no pressure is built up in the cylinder and the oil flows back to the
pump without pressure. If the deadman's handle is released, it returns automatically to the neutral
position and the piston immediately stops moving.
In tools like cutters, spreaders and combi tools the axial movement of the piston starts a mechanism
that then makes a cutting or spreading movement.
