Installing or removing bit
CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Use only the driver bit or socket bit shown in the figure
below.
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. 2)
To remove the bit, pull the sleeve in the direction of the
arrow and pull the bit out firmly.
CAUTION:
• This tool is designed to drive wood screws. Do not use
this tool to drive machine screws or bolts. The tool may
be damaged.
• 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.
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.
Switch action (Fig. 3)
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 trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Reversing switch action (Fig. 4)
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.
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 counter-
clockwise rotation. When the switch lever is in the neutral
position, the switch trigger cannot be pulled.

Characteristics of Cordless Oil-Impulse Driver
The Makita Cordless Oil-Impulse Driver is a hydraulically
operated impact tool using oil viscosity to produce
impacts. Since oil viscosity changes with the tempera-
ture, be aware of the following two points when operating
the tool.
1. If the tool itself is cold, it may take longer to set
screws because of the low fastening torque when
you begin operation. After fastening about ten
screws, however, the fastening torque will become
normal.
2. The tool can overheat, causing a failure or hand
burn if you operate it continuously for long hours. Let
the tool cool off for more than 30 minutes before
changing batteries during a long, continuous job.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work on
the tool.
Replacement of carbon brushes (Fig. 5 & 6)
Replace carbon brushes when they are worn down to the
limit mark. Both identical carbon brushes should be
replaced at the same time.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
