For machine with pull-type sleeve
To install the bit, pull the sleeve in the direction of the
arrow (B) and insert the bit into the sleeve as far as it
will go. Then release the sleeve to secure the bit in
place.
To remove the bit, pull the sleeve in the direction of
the arrow (B) 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.
Switch action (Fig. 4)
CAUTION:
Before inserting the battery cartridge into the
machine, always check to see that the switch trigger
actuates properly and returns to the ''OFF'' position
when released.
To start the machine, simply pull the trigger. Release
the trigger to stop.
Reversing switch action (Fig. 5)
CAUTION:
• Always check the direction of rotation before opera-
tion.
• Use the reversing switch only after the machine
comes to a complete stop. Changing the direction of
rotation before the machine stops may damage the
machine.
This machine has a reversing switch to change the
direction of rotation. Slide the reversing switch to the
right for clockwise rotation or to the left for counter-
clockwise rotation.
Adjusting the fastening torque (Fig. 6)
1. To adjust the fastening torque, first slide the
stopper toward the switch trigger.
2. Then turn the adjusting knob so that the desired
number will be aligned with the arrow on the
machine body. The adjusting knob should be
turned only within the numbered range.
3. For 6791D, 6791DW and 6793D
Aligning the numbers 2, 3, 4 ..... 12 provides the
approximate 20, 30, 40 ..... 120 kg . cm of fasten-
ing torque respectively.
For 6792D, 6792DW and 6794D
Aligning the numbers 2, 3, 4 ..... 8 provides the
approximate 20, 30, 40 ..... 80 kg . cm of fastening
torque respectively.
For 6795D
Aligning the numbers 2 ..... 12 provides the
approximate 5 ..... 35 kg . cm of fastening torque
respectively.
4. After aligning the knob to the desired position in
relation to the arrow, release the stopper.
5. The correct fastening torque may vary depending
upon the kind of the screw/bolt and the material of
the workpiece to be fastened. Before actual
operation, drive a trial screw into your material or
a piece of duplicate material to determine which
torque level is required for a particular application.

Screwdriving operation (Fig. 7)
Place the point of the driver bit in the screw head and
apply pressure to the machine. Then switch the
machine on. When the clutch cuts in, the motor will
stop automatically. Then release the switch trigger.
When the battery capacity decreases to a certain
level, the motor will not start even if you press the
switch trigger. This mechanism prevents poor fasten-
ing caused by battery voltage-drop. Charge the bat-
tery cartridge to resume operation.
NOTE:
• Use the proper bit for the head of the screw that you
wish to use.
• Make sure that the driver bit is inserted straight in
the screw head, or the screw and/or bit may be
damaged.
• There is a very slight possibility that the machine will
not be turned on even if you pull the switch trigger.
If this occurs, turn the sleeve slightly by hand and
pull the switch trigger again. The machine will be
turned on.
MAINTENANCE
CAUTION:
Always be sure that the machine is switched off and
the battery cartridge is removed before carrying out
any work on the machine.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
