Installing or removing socket
Important:
Always be sure that the machine is switched off and
the battery cartridge is removed before installing or
removing the socket.
For machine with square drive (Fig. 3 & 4)
Use 9.5 mm square drive socket with a hole for detent
pin which is available on the market. (Note: Use
6.35 mm square drive socket when using the machine
with 6.35 mm square drive.)
To install the socket, depress the detent pin on the
square drive with your finger and push the socket onto
the square drive until the detent pin is inserted into the
hole in the socket.
To remove the socket, depress the detent pin with a
small hand tool and pull off the socket.
For machine with round drive (Fig. 5)
Use a bit with Form C 6.3 shank which is available on
the market. The bit can be inserted directly into the
round drive and held in place.
To install the bit, push it firmly into the round drive.
To remove the bit, grasp it with a pair of pliers and pull
it out of the round drive. Sometimes, it helps to wiggle
the bit with the pliers as you pull.
Switch action (Fig. 6)
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. 6)
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 up for
clockwise rotation or slide it down for counterclock-
wise rotation.
Overload protector
For 6704D and 6704DW
The overload protector automatically cuts out to break
the circuit whenever heavy work is prolonged. Wait
20 – 30 seconds before resuming operation.

Adjusting the fastening torque (Fig. 7)
The fastening torque can be adjusted infinitely from
approx. 20 kg·cm to 80 kg·cm. To adjust it, loosen the
two screws and turn the adjusting ring. Then tighten
the screws to secure the adjusting ring. Refer to the
table below for relation between the numbers on the
adjusting ring and the fastening torque to be obtained.
Numbers on

(Example)
35 kg·cm of fastening torque can be obtained when
the number 2 is aligned to the red mark.
NOTE:
• Always tighten the two screws to secure the adjust-
ing ring after adjusting the fastening torque.
• The fastening torque may differ depending upon the
kind of screws, the type of materials to be fastened,
etc. Before starting your job, always perform a test
operation to verify the adequate fastening torque.
Installing set plate (Fig. 8)
Always install the set plate when using battery car-
tridges 9100, 9102 or 9102A. Install the set plate on
the machine with the screw provided as shown in
Fig. 8.
Operation
The proper fastening torque may differ depending
upon the kind or size of screws, the type of materials
to be fastened, the condition of the threads, etc.
Before starting your job, always perform a test opera-
tion to verify adequate fastening torque.
Hold the machine firmly with both hands whenever
possible and place the socket over the bolt or nut.
Then turn the machine on. As soon as the bolt or nut
becomes tight, the clutch will cut in and the motor will
stop automatically. Release the switch trigger.
When fastening machine screws, use the proper
screwdriver bit shown in Fig. 9. It is commonly avail-
able on the market.
