9.2 Function of the main switch
With the main switch (see picture 9) the pump can be switched
on or off. In the ”on” position the main switch is illuminated.
To prevent damage of the pump unit through voltage peaks a
circuit breaker is integrated into the main switch. When activated
the circuit breaker would set the main switch automatically to the
”off” position. As soon as the voltage peak is over the pump
can be switched on again.
9.3 Working with pump and connected rescue tool
When the rescue tool is connected with the pump (see chapter 8.2.3), the dump valve must be
closed (see chapter 8.2.2). The tool is now supplied with hydraulic oil and can be operated by
means of the star grip.
9.4 The charge indication panel
When the pump is switched on, the charge condition of the battery can be visually checked with
three lights in different colours:
-
”green” means that the battery is full
- ”yellow” means that the battery is approx. half full
- the red light goes on when the battery is almost empty
Should you observe a loss of speed of the rescue tool and the red light is permanently on, charge
the battery immediately or change it against a fresh one. Do not continue with the operation until
the motor stops !
Otherwise there is the risk of the battery becoming deep discharged which would reduce its lifetime.
Remark: The ”true” battery capacity can be seen only when the pump is in no-load condition.
Depending on the stress situation of the rescue tool the battery voltage may vary so that the red
light goes on just for a second, e. g. when an extreme cutting job is made.
9.5 External power supply
The P 600 OB pump can optionally be driven by an external battery
e. g. the truck battery. It must be made sure, however, that the
battery has 24 V and no more than 20 A ! Never exceed these
valnes, otherwise the pump may be destroyed.
For connection of such a battery the P 600 OB is equipped with a
connection point (see picture 10). A suitable connection cable can
be supplied upon request.
9.6 Change of battery
For changing the battery refer to chapter 8.2.1.
9.7 The indicator pin
On top of the pump unit is a pin (item 2, see cover page) which is connected with the hydraulic oil
reservoir. Should the reservoir be overfilled the pin would be pushed upwards so that the red shaft
becomes visible. In this case excess oil must be drained from the reservoir (see chapters 9.8 and
10.3).
