Driving Operation; Maintenance - Makita DFR452 Instruction Manual

Using hole
WARNING:
Never use the hanging hole for
unintended purpose, for instance, tethering the
tool at high location. Bearing stress in a heavily
loaded hole may cause damages to the hole, result-
ing in injuries to you or people around or below you.
► Fig.17: 1. Hanging hole
Use the hanging hole at the bottom rear of the tool to
hang the tool on a wall using a hanging cord or similar
strings.
OPERATION

Driving operation

NOTICE:
Always check the driver bit carefully
for wear before driving operations. Replace a worn
driver bit or poor fastening may result.
NOTICE:
Always hold the tool squarely against
the driving surface. Holding it at an angle may dam-
age the screw heads and cause wear on the driver
bit. This may also lead to poor fastening.
NOTICE:
Always keep the tool firmly against the
driving surface until the driving is over. Failure to
do so may cause insufficient fastening of screws.
NOTICE:
Be careful not to drive a screw onto
another screw already fastened.
NOTICE:
Do not operate the tool without screws.
It will damage the driving surface.
NOTICE:
Do not apply oil or grease on the slid-
ing surface of the feeder box.
Switch on the tool by pulling the switch trigger. Hold the
tool squarely and firmly up against the driving surface. A
screw will be automatically carried to the driving posi-
tion and fastened.

NOTE: While selecting push drive mode and locking
the trigger on, the motor does not rotate under no
load to minimize power consumption.

and apply forward pressure to the tool.
The screw will be automatically carried to the driving
position and driven at full speed.

Driving in corner
CAUTION:
Driving at a position closer than
15 mm to the wall or driving with the stopper base
in contact with the wall may damage the screw
heads and cause wear on the driver bit. This may
also lead to poor fastening of screws and malfunction
of the tool.
This tool can be used to drive at a position 15 mm away
from the wall as shown in the figure.

Unfastening operation
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.
The tool allows you to change the direction of driver bit
rotation with ease, either towards the right (clockwise)
to tighten a screw or towards the left (counterclockwise)
to loosen a screw.
1. Depress the reversing switch lever from the B side
for counterclockwise rotation.
