Malfunction
Possible cause
Action to be taken
Fasteners are frequently
driven to inadequate depth.
Driving power is too low.
▶
Move the fastener driving depth
adjustment slider to the
+
position.
The fasteners are too long.
▶
Use shorter fasteners.
The supporting material is too
hard.
▶
Consider using a DX fastening
tool.
The inlet/outlet valve is clogged or
covered over.
▶
Clean the fastening tool and
check how it is held.
Fasteners are frequently
driven too deeply.
Driving power is too high.
▶
Move the fastener driving depth
adjustment slider to the
‒
position.
The fasteners are too short.
▶
Use longer fasteners.
Fasteners break.
Driving power is too low.
▶
Move the fastener driving depth
adjustment slider to the
+
position.
The fasteners are too long.
▶
Use shorter fasteners.
The supporting material is too
hard.
▶
Consider using a DX fastening
tool.
The fastener guide is not held per-
pendicular to the working surface.
▶
Press the nosepiece against the
working surface while keeping
the tool perpendicular to the
surface.
Fasteners bend.
Driving power is too low.
▶
Move the fastener driving depth
adjustment slider to the

Fasteners do not hold in steel
base material.
The supporting material is too thin.
▶
Use a different fastening
method.
The content of the gas can is
inadequate for the number of
fasteners in the package.
High gas consumption due to fre-
quent compression of the tool
nosepiece without driving a fas-
tener.
▶
Avoid compressing the tool
nosepiece without driving a
fastener.
The tool remains compressed
(nose does not extend when
pressure is released).
Incorrect piston position.
▶
Remedy the incorrect piston
position. → page 24
The nail detector is jammed and
the
