The fastener guide is not held per-
pendicular to the working surface.
Driving power is too low.
The fasteners are too long.
The fastener guide is not held per-
pendicular to the working surface.
The supporting material is too thin.
High gas consumption due to fre-
quent compression of the tool
nosepiece without driving a fas-
tener.
A fastener has jammed in the fas-
tener guide.
The fastener guide is not held per-
pendicular to the working surface.
Wrong type of fastener used.

The nail pusher was not moved
forward.
Action to be taken
▶ Press the nose of the tool
against the working surface,
keeping the fastener guide
perpendicular to the surface
(see driving nails, → page 12).
▶ Move the fastener driving depth
adjustment slider to the +
position.
▶ Use shorter fasteners.
▶ Use the support leg on an even
surface and make sure that it's
in contact with the surface (see
support leg → page 9).
▶ Press the nose of the tool
against the working surface,
keeping the fastener guide
perpendicular to the surface
(see driving nails, → page 12).
▶ Use a different fastening
method.
▶ Avoid compressing the tool
nosepiece without driving a
fastener.
▶ Remove the fastener guide
→ page 14.
▶ Release the jammed fastener.
▶ Clean the fastener guide.
▶ Remove foreign objects from
the area of the fastener guide.
▶ Use the support leg on an even
surface and make sure that it's
in contact with the surface (see
support leg → page 9).
▶ Press the nose of the tool
against the working surface,
keeping the fastener guide
perpendicular to the surface
(see driving nails, → page 12).
▶ Use a suitable type of fastener.
▶ Consider using a DX fastening
tool.

guide it forward as far as it will
go.
