Overload Protection - Makita DGA402 Betriebsanleitung

Protections against other causes
Protection system is also designed for other causes
that could damage the tool and allows the tool to stop
automatically. Take all the following steps to clear the
causes, when the tool has been brought to a temporary
halt or stop in operation.
1. Turn the tool off, and then turn it on again to
restart.
2. Charge the battery(ies) or replace it/them with
recharged battery(ies).
3. Let the tool and battery(ies) cool down.
If no improvement can be found by restoring protection
system, then contact your local Makita Service Center.
Indication lamp with multi function
► Fig.3: 1. Indication lamp
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with
the slide switch positioned in the "O (OFF)", the indica-
tion lamp blinks quickly for approximately one second.
If it does not blink so, the battery cartridge or indication
lamp may be broken.

Overload protection

• When the tool becomes overloaded, the indica-
tion lamp lights up. When the load on the tool is
reduced, the lamp goes out.
• If the tool continues to be overloaded and the indi-
cation lamp continues to light up for approximately
two seconds, the tool stops. This prevents the
motor and its related parts from being damaged.
• In this situation, move the slide switch to the "O
(OFF)" position once. And then move it to the "I
(ON)" position again to restart.
Battery cartridge replacing signal
When the remaining battery capacity is low, the indica-
tor lamp lights up during operation earlier than that of
high battery capacity.
Accidental re-start preventive
function
• Even if the battery cartridge is inserted on the tool
with the slide switch in the "I (ON)" position, the
tool does not start. In this situation, the lamp flick-
ers slowly. It indicates that the accidental re-start
preventive function is at work.
• To start the tool, first slide the slide switch toward
the "O (OFF)" position and then slide it toward the
"I (ON)" position.

WARNING:
Never actuate the shaft lock when
the spindle is moving. It may cause serious injury or
