Instructions for using the OKTOPUS
®
3.1 Electrical power supply
Power supply is effected by a 24 V / 4,5 Ah battery system (2 pcs 12 V batteries).
The battery’s charge level is monitored through a charge indicator according to figure 4.
Light-emitting diodes (LED) in the signal colors green, yellow and red indicate the current
charge level after the OKTOPUS
®
has been turned on.
The following charge levels can be read from the charge indicator:
⇒
If at least one green LED is illuminated the battery is charged. You can operate the
OKTOPUS
®
.
⇒
If the third LED from the left is illuminated (yellow LED), you should charge the battery.
⇒
If the second LED from the left (yellow LED) is flashing, or the second LED from the left
(yellow LED) and the red LED are flashing alternately, the battery needs to be charged
instantly in order to avoid deep discharge and by that possible damage.
The charge indicator is arranged on the device according to figure 1.

Do not use the OKTOPUS

, if the yellow LED is flashing, or the yellow and
the red LED are flashing alternately. Possibly sucked loads shall be low-
ered. The OKTOPUS
®
has to be charged instantly in order to avoid deep
discharge and by that possible damage to the battery.
The user has to ensure that the battery is properly charged when operating
the OKTOPUS
®
.
The charge indicator only indicates the current voltage level of the battery.
It does not give any reliable information regarding the battery’s capacity.
The charge indicator responds rather slowly. In order to assess the voltage
level realistically after the charging process (see point 4.4) you have to run
the vacuum pump of the device for approximately 2 minutes, and then use
the indicated charge level of the battery as a basis for assessing how to
employ the device.
If this green LED is illuminated
the battery is fully charged.
