Makita DDA340 Betriebsanleitung Seite 7

NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off the power to
extend tool and battery life. The tool will automatically
stop during operation if the tool or battery is placed
under one of the following conditions:
Overload protection
This protection works when the tool is operated in a
manner that causes it to draw an abnormally high cur-
rent. In this situation, turn the tool off and stop the appli-
cation that caused the tool to become overloaded. Then
turn the tool on to restart.
Overheat protection
This protection works when the tool or battery is over-
heated. In this situation, let the tool and battery cool
before turning the tool on again.
Overdischarge protection
This protection works when the remaining battery
capacity gets low. In this situation, remove the battery
from the tool and charge the battery.
Switch action
CAUTION:
Before installing the battery car-
tridge into the tool, always check to see that the
switch lever actuates properly and returns to the
"OFF" position when released.
CAUTION:
Be sure to hold the tool firmly
before the tool is switched off.
► Fig.3: 1. Switch lever
To start the tool, simply pull the switch lever. Tool speed
is increased by increasing pressure on the switch lever.
Release the switch lever to stop.
Lighting up the front lamp
CAUTION:
Do not look in the light or see the
source of light directly.
► Fig.4: 1. Lamp
Pull the switch lever to light up the lamp. The lamp
keeps on lighting while the switch lever is being pulled.
The light automatically goes out approximately 10 sec-
onds after the switch lever is released.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Reversing switch action
► Fig.5: 1. Reversing switch lever
CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may dam-
age the tool.
CAUTION:
When not operating the tool,
always set the reversing switch lever to the neu-
tral position.
This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the
A side for clockwise rotation or from the B side for coun-
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch lever cannot be pulled.
ASSEMBLY
CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
Installing side grip (auxiliary handle)
CAUTION:
Always be sure that the side grip is
installed securely before operation.
Screw the side grip on the tool securely. The side grip
can be installed on either side of the tool, whichever is
convenient.
