English 8 Before Starting Work
￭ A battery fire can be dangerous. To reduce the risk of
severe personal injury and property damage in the event
of fire:
– Evacuate the area. Fire can spread rapidly. Stay
clear of any vapors generated and maintain a safe
distance.
– Contact the fire department.
– Although water can be used to put out a battery fire,
use of a multi-purpose dry chemical fire extinguisher
is preferable.
– Consult the fire department regarding proper
disposal of a burned battery.
8.1 Preparing the Trimmer for Operation
Before starting work:
► Fully charge the battery, @ 9.
► Mount the loop handle, @ 11.1.
► Mount a deflector that is approved for use with the cutting
attachment you intend to use, @ 11.4.1 and @ 25.
► Mount an approved mowing head, grass cutting blade or
brush knife, @ 11.5.1 or @ 11.6.1 and @ 25.
► If using a metal cutting attachment, mount the barrier bar,
@ 11.3.

9.1 Setting up the Charger
WARNING
Read and follow the safety precautions on the battery and
charger and all warnings and instructions that accompany
those products. To reduce the risk of short circuit, which
could lead to electric shock, fire and explosion, make sure
the charger and its components are dry and not damaged;
operate the charger indoors at an appropriate ambient
temperature.
WARNING
A typical household electric circuit is between 15 and 20
amps. A single STIHL AL 500 charger draws approximately
4.8 amps. A single AL 300 charger draws approximately
4.4 amps. To reduce the risk of fire from overloading an
electrical circuit:
► Ensure the electrical system is rated to withstand the
expected electrical draw before charging your battery.
► Charge multiple batteries one at a time or on separate
circuits, unless you know your circuit can handle the total
expected draw from multiple chargers.
WARNING
Since the charger heats up during the charging process, do
not operate the charger on a combustible surface or in a
location where combustible gases, liquids, vapors, dusts or
other materials and substances are present.
