Operation - Makita DFS441 Betriebsanleitung

• When the remaining battery capacity gets low:
If any operation of the switch trigger, the motor will
remain stopped. At this time, remove the battery
cartridge from the tool and charge it .
Indicating the remaining battery capacity
Only for battery cartridges with the indicator (Fig. 3)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for a few seconds.
Indicator lamps
Lighted Off
NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
Switch action (Fig. 4)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To start the tool, simply pull the switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.

Reversing switch action (Fig. 6)
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
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
When not operating the tool, always set the reversing
switch lever to the neutral position.
Depth adjustment (Fig. 7)
The depth can be adjusted by turning the locator. Turn it in
"B" direction for less depth and in "A" direction for more
depth. One full turn of the locator equals 2 mm change in
depth. (Fig. 8)
Adjust the locator so that the distance between the tip of
the locator and the screw head is approximately 3 mm as
shown in the figures. Drive a trial screw into your material
or a piece of duplicate material. If the depth is still not
suitable for the screw, continue adjusting until you obtain
the proper depth setting.
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 or removing the bit (Fig. 9)
To remove the bit, pull the locator. Then grasp the bit with
a pair of pliers and pull the bit out of the magnetic bit
holder. Sometimes, it helps to wiggle the bit with the pliers
as you pull. (Fig. 10)
To install the bit, push it firmly into the magnetic bit holder.
Then install the locator by pushing it firmly back.
Hook (Fig. 11)
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.

Apply pressure to the tool and start it. Withdraw the tool
as soon as the clutch cuts in. Then release the switch
trigger.
CAUTION:
• When fitting the screw onto the point of the bit, be
careful not to push in on the screw. If the screw is
pushed in, the clutch will engage and the screw will
