Operation; Maintenance; Optional Accessories - Makita DFT022F Instruction Manual

OPERATION

Screwdriving operation
Place the point of the driver bit in the screw head and
apply pressure to the tool. Then switch the tool on.
When the clutch cuts in, the motor will stop automati-
cally. Then release the switch trigger.
NOTE:
• Make sure that the driver bit is inserted straight
in the screw head, or the screw and/or bit may
be damaged.
Limits of fastening capacity
Use the tool within the range of the revolution angle up
to 360°. If you use the tool beyond the upper limit of this
range, the clutch does not work. And the tool cannot
deliver enough fastening torque (LED indicator flickers
in red and green alternatively).
NOTE:
• The revolution angle means the angle which
a screw/bolt revolves when the tool attains to
100% from 50% of desired torque.
• Use of a low temperature conditioned battery
cartridge may sometimes give warning for
battery cartridge capacity by warning lamp and
beeper which makes the tool stop immediately.
In this case, the fastening capacity may be
inferior to the specification on this manual even
if a charged battery cartridge is used.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before attempt-
ing to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
