Air duster
CAUTION:
Do not aim the ejection port of the
air duster to someone. Also, keep your hands and
foot away from the ejection port. If the air duster
button is accidentally pushed, it may cause a per-
sonal injury.
CAUTION:
Always check your surroundings
before using the air duster. Blown dust or objects
may hit someone.
CAUTION:
Do not connect or disconnect the
air hose while pushing the air duster button.
The air supplied to the tool can also be used as an air
duster. You can clean the work area by pressing the
button on the grip end.
► Fig.8: 1. Button
NOTICE:
After using the air duster, the driving force
of the tool will temporarily decline. Wait until the air
pressure recovers in this case.
NOTICE:
Perform a test blow if you use the air
duster immediately after the oil was applied. The oil
may be sprayed with the air.
ASSEMBLY
CAUTION:
Always be sure that the air hose
is disconnected and no fastener is loaded before
carrying out any work on the tool.
Loading screws
1. Disconnect the air hose.
2. Open the door while pressing down the lever.
► Fig.9: 1. Door 2. Lever
3. Open the magazine cap.
► Fig.10: 1. Magazine cap
4.
Load screws into magazine. Set the first screw to
the feeding claw. If the driver bit hinders the first screw
to be set, turn the tool upside down (screw tip on top).
This will return the driver bit to its designated position.

5. Place the rest of screws in the screw channel and
close the magazine cap.
6.
Slowly close door until lever is completely latched.
Replacing driver bit
1. Remove the bolts on the driver guide and the
magazine with a hex wrench then remove the driver
guide unit from the body.

NOTICE:
Be careful not to lose the springs, gasket,
and screws. They may fall off when removing the
driver guide unit.
2. Turn the driver bit clockwise while pulling it out.
The driver bit will be removed. You can use a plier to
turn the bit, however do not pinch the tip of the bit.
► Fig.13
3. Insert a new driver bit and turn counterclockwise
while pushing it in. Make sure that the threads on the
driver bit catches the base.
► Fig.14
NOTE: The driver bit can be rotated endlessly. Stop
rotating the driver bit when it is secured.
4. Push the driver bit to the end. Attach the driver
guide unit to the body and secure with bolts.
► Fig.15
NOTICE:
Be sure to return the gasket and springs to
the original position before attaching the driver guide
unit. Also note that the spring on the trigger base is
installed straight as shown in the figure.
OPERATION
Screwing
CAUTION:
The utilized air pressure must
be between 1.76 - 2.26 MPa. Do not repeatedly
drive screw(s) in on top of a screw that has been
already driven in.
CAUTION:
Do not repeatedly drive screw(s)
in on top of a screw that has been already driven
in. This tool is not an impact gun, so it requires a
reasonable amount of pressing.
CAUTION:
If the contact arm is not pressed
sufficiently, the screw may not drive in flush to
workpiece, or come out.
CAUTION:
Always press the contact arm at a
right angle onto the workpiece and then drive in
screw. Using with the intermittent-drive action is
recommended to ensure proper screw driving.
1. Lightly press the end of the contact arm onto a
workpiece.
► Fig.16: 1. Contact arm
2.
Pull the trigger and hold it until the tool stops run-
ning. If the trigger is released too soon, the screw may
not be driven in flush to workpiece, and/or the screw
feeding may be impaired.
► Fig.17
Changing drive action
This tool employs two driving actions; intermittent drive
and continuous drive.
► Fig.18: 1. Intermitent drive action 2. Continuous
drive action
Intermittent drive action
Intermittent drive action drives only one screw when
the contact arm is pressed against the workpiece and
the trigger is pulled. To drive the next screw, release the
