Recommended Grip - Panasonic EY7549 Instructions D'utilisation

• If the tool is used in cold-temperature
conditions (such as during winter) or if
it is frequently stopped during use, the
overheating protection feature may not
activate.
• The ambient temperature range is
between 0°C (32°F) and 40°C (104°F).
If the battery pack is used when the
battery temperature is below 0°C
(32°F), the tool may fail to function
properly.
• When charging a cool battery pack
(below 0°C (32°F)) in a warm place,
leave the battery pack at the place and
wait for more than one hour to warm
up the battery to the level of the ambi-
ent temperature.
• The performance of the EY9L42 dete-
riorates significantly at and below 10°C
due to work conditions and other fac-
tors.
(3) Battery low warning lamp
Off
(normal
operation)
Excessive (complete) discharging of
lithium ion batteries shortens their service
life dramatically. The driver includes a
battery protection feature designed to
prevent excessive dis charging of the
battery pack.
• The battery protection feature acti-
vates immediately before the battery
loses its charge, causing the battery
low warning lamp to flash.
• If you notice the battery low warning
lamp flashing, charge the battery pack
immediately.
• If it is started with too little battery
power remaining, the tool may stop
operating without the battery low warn-
ing lamp flashing first. This indicates
that there is too little battery power
remaining to use the tool, and the bat-

feature active
tery pack should be charged before
further use.
• If the tool is subject to a sudden load
during use that causes the motor to
lock up, the overdischarge preven-
tion sensor may be triggered, and the
battery low warning lamp may flash.
The lamp will stop flashing once you
address the cause of the motor's lock-
ing up and cycle the trigger.
• The battery protection feature may
activate when a high load is abrupt-
ly placed on the motor, even if ample
battery charge remains. In this case,
both the battery low warning lamp and
LED light will flash.
• If both the battery low warning lamp
and LED light flash, reduce the force
with which you are pushing on the
driver or, if using a drill driver, adjust
the speed switch to a lower setting.

Recommended Grip

Use the grip to hold and operate the
driver with one hand. If the job requires
additional force, you can push against
the rear end of the driver with your other
hand.
