Opening the driver channel:
Strike the tool at an angle as in fig. 1 so that the guide plate
(c) is pushed out of place.
Closing the driver channel:
Strike the tool vertically as in fig. 2 so that the guide
plate is pushed back into the working position.
The smooth running of the nosepiece must be
checked!
When connecting the tool, it must contain no
fasteners.
8 TROUBLES AND REMEDIES
Disconnect nailer from hose before servicing. When connecting the tool, it must contain no fasteners.
TROUBLE
Air leaking from exhaust
port.
Blow does not take place.
Idle impact or fasteners
(staples or nails) are not
fully driven in.
Guide plate (c) is loose on
the tool or the nosepiece (b)
is jammed.
Nailer operates too slowly.
Set of wear-and-tear parts
During repair replacement of parts the special grease (code no. 68 3868) must be applied to the surface of
the cylinder and the counter surfaces of the O-rings.
POSSIBLE CAUSE
O-rings (e, f, h, i) damaged or dirty.
Control parts move with difficulty
after long term storage.
Bushing (p) damaged.
Tool exhausts considerably in the
lowest position of the piston, O-ring
(t), bumper (v), worn or damaged. No
backstroke.
Tool without sufficient lubrication.
Air pressure too low.
Tool jumps.
Connection hose too long. Diameter
reduced in the air line or in the
maintenance unit (fall of pressure).
Piston completely (r) damaged.
Tip of driver worn.
Penetration setting wrongly adjusted.
Misshapen fasteners have pushed
the guide plate up or jammed the
nosepiece.
Bad or wrong fastener strips (strip is
jammed and thus not being pushed

Press tool more firmly onto the
workpiece.
Investigate and correct trouble.
Replace piston. At the same time
check bumper (v) for wear.
Re-grind the face of the driver tip such
that it is square to its axis.
Set correctly according, see 5.
