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
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. 9)
To install the bit, push it firmly into the magnetic bit holder.
Then install the locator by pushing it firmly back. (Fig. 10)
Bit storage (Fig. 11)
Fit the bit into the protrusion at the tool.
Carry hook
The carry hook is convenient for temporarily hooking the
tool. It can be installed on either side of the tool.
When removing the carry hook, widen it by pressing its
right ends ON BOTH SIDES in the directions of arrow (1)
and raise it in the direction of the arrow (2). (Fig. 12)

OPERATION

Screwdriving operation (Fig. 13)
Fit the screw on the point of the bit and place the point of
the screw on the surface of the workpiece to be fastened.
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
rotate suddenly. This could damage a workpiece or
cause an injury.
• Make sure that the bit is inserted straight in the screw
head, or the screw and/or bit may be damaged.

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.
Replacing carbon brushes (Fig. 14)
Replace when they wear down to the limit mark. Keep the
carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove two screws then remove the
front cover. (Fig. 15)
Raise the arm part of the spring and then place it in the
recessed part of the housing with a slotted bit screwdriver
of slender shaft or the like. (Fig. 16)
Use pliers to remove the carbon brush caps of the carbon
brushes. Take out the worn carbon brushes, insert the
new ones and replace the carbon brush caps in reverse.
(Fig. 17)
Make sure that the carbon brush caps have fit into the
holes in brush holders securely. (Fig. 18)
Reinstall the front cover and tighten two screws securely.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized or Factory Service
Centers, always using Makita replacement parts.
