6.1 General
The equipment of a rescue system must always be ready for use. That means the equipment must be
checked and inspected directly after use, before it is put away.
WARNING
Make sure you are up to date on all safety regulations and that you have mastered the use of
all equipment of the system you are going to work with.
6.2 Before use
• Before use, always check the State Of Charge of the battery pack. See section 3.4.
6.3 During use
6.3.1 Changing the battery pack
The battery pack has a LED indicator that indicates the approximate battery level (the State Of Charge).
No lit LED indication will be shown during the operation of the tool.
Caution
• Many cycles in a short time may cause temperature increase above allowed limits. The
battery protection will shut down the battery until the temperature lowers to a value within
allowed limits.
• Using the battery pack at temperatures above 45 °C (113 °F) reduces the life time of the
battery pack.
See Fig. 8.
• Switch off the tool using the on/off switch.
• Remove the battery pack.
• Place a new battery pack on the tool.
• Switch on the tool using the on/off switch.
WARNING
If the battery pack is removed without stopping the tool, the tool might start directly after the
new battery pack is installed.
Note
It is highly recommended to have at least one fully charged spare battery pack available at
all times.
