For tool with deep bit hole: A=17mm, B=14mm
Do not use any other driver bit or socket bit.
To install the bit, pull the sleeve in the direction of the
arrow and insert the bit into the sleeve as far as it will go.
Then release the sleeve to secure the bit.
Fig.9
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
NOTE:
• If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and
the bit will not be secured. In this case, try
re-inserting the bit according to the instructions
above.
OPERATION
Fig.10
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 automatically. 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 ﾟ. 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 blinks in
purple slowly or lights up in purple).
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 attempting to
perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may
result.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
