System Operation; Charging The Battery Pack - Holmatro PSP40 Manual

5 Operation
5.1

System operation

In a battery tool the hydraulic pump is integrated. An electric motor operates the hydraulic pump. The
electric motor is energized by a battery pack or from an external electric power source. This pump
displaces hydraulic oil and can build up pressure. The hydraulic pump is connected directly to the
hydraulic cylinder.
The hydraulic cylinder contains a plunger that can move axially. If the cylinder is filled with oil from the
bottom, the piston moves out. If the cylinder is filled from the top, the piston moves in. The direction in
which the piston moves is controlled by the so-called deadman's handle. The deadman's handle can be
rotated by the user to control the movement. If the deadman's handle is released, it returns
automatically to the neutral position and stops the movement of the tool.
In tools like cutters, spreaders and combi tools the movement of the piston drives a mechanism to make
a cutting or spreading movement.

Charging the battery pack

• Read the instructions of the battery charger before you charge the battery pack.
• Only use one of the prescribed Holmatro battery chargers to charge the battery pack.
• Best results and longest life of the battery pack are achieved when the battery pack is charged in a
dry environment at a temperature between 18 °C and 24 °C (64 °F and 75 °F).
• The SOC indicator on the battery pack shows the state of charge of the battery pack.
• The maximum capacity of the battery pack is achieved when it has been charged and discharged
some times.
• Always charge the battery pack, also if it has been used for a short time.
• The battery pack can stay connected to the battery charger for an indefinite period of time, because
it is protected against overcharging.
NOTICE
When the battery pack is not in use, it is advised to keep it connected to the battery charger
(connected to a power source) at all times. When the battery pack is full, the battery charger
automatically switches on and off at regular intervals to keep the battery level at 100%.
After deep discharge of the battery pack, charge the battery pack for 24 hours. If the battery
pack is not completely charged after 24 hours, contact your local Holmatro dealer.
5.3 Installing the battery pack
Refer to Fig. 6
• Put the battery pack in the battery pack fitting / adapter fitting until the battery pack locks.
5.4 Connecting to an external power source
See Fig. 4.
Apart from using the battery pack, the tool can also be connected to the mains by the special mains
connector. Use only the original mains connector for this purpose.
• Slide the adapter of the mains connector in the battery pack fitting / adapter fitting until the battery
pack lock snaps tight.
• Insert the plug of the mains connector into the appropriate power outlet.
