English 13 STIHL AR Backpack Battery
If three LEDs glow red continuously: the power tool motor is
too hot. Allow the motor to cool down.
If three LEDs flash red when you activate the trigger switch:
the power tool has an electrical malfunction. Do not operate
the power tool. Have it checked by an authorized STIHL
servicing dealer before use or storage.
For troubleshooting information, @ 24.
12.2.3 Charge Status
The LEDs and acoustic signals on the battery also indicate
the battery's state of charge.
To determine the battery's state of charge:
► Press the button (1) on the backpack battery.
A single short beep will be emitted. The LEDs on the battery
will glow or flash green for about 5 seconds and indicate the
state of charge (see illustration).
For example:
If six green LEDs glow continuously: full charge.
If one green LED is flashing and four long beeps are emitted:
less than 20 % charge.
13.1 Positioning and Adjusting the Connecting Cord
WARNING
If using an AR series battery or AP series battery in a battery
bag with connecting cord always use a lift bucket for in-tree
surgery and maintenance. Do not climb in the tree.
WARNING
Place your left hand on the front handle and your right hand
on the control handle. Left-handers must follow these
instructions too. (See illustration, Chapter @ 5.5.2). One-
handed operation increases the risk of injury. Accordingly, to
reduce the risk of personal injury, run the connecting cord
through the guide on the shoulder strap on the opertor's right
side only. Never run the cord through the guides on the
shoulder strap on the operator's left side.
WARNING
To reduce the risk of injury from tripping or losing control of
the chain saw, always secure the connecting cord through
the backpack guides and with the hook and eye fasteners as
described below. Position and secure the connecting cord
on your right side and so that it will not interfere with proper
working technique or your ability to maintain control of the
chain saw.
WARNING
Manage the cord to prevent it from contacting the saw chain
or catching on objects, which could cause you to lose
balance or control of the chain saw, resulting in serious
personal injury and property damage.
The connecting cord can be secured in different positions
and adjusted to suit the height and reach of the operator.
