The smooth-running of the safety yoke must be
tested!
When the safety yoke (a) has been pressed it must
return to its initial position automatically.
Before connecting the tool make sure it contains 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 staples are
not fully driven in.
Nailer operates too
slowly.
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-ring (e) or valve slide (f) is
damaged or dirty.
Face of the cylinder (g) is damaged.
Control parts move with difficulty
after long term storage.
Driver is jammed by a staples.
Tool is applied too weakly or for too a
short Time.
Tool exhausts considerably in the
lowest position of the piston, O-ring
(t), bumper (v), sealing disk (h) worn or
damaged. No backstroke.
Penetration setting wrongly adjusted.
Tool without sufficient lubrication.
Air pressure too low.
Tool jumps.
Connection hose too long. Diameter
reduced in the air line or in the mainte-
nance unit (fall of pressure).
Piston completely (r) damaged.
Tip of driver worn.
O-ring (e) or valve slide (f) damaged or
requiring lubrication.
Safety yoke (a) or safety bracket (b)
sluggish.
Release valve (w) damaged.
7 ACCESSORIES
Balancer for 20–30 N (2.0–3.0 kp),
cable travel 2.0 m (6.5 ft)
Suspension
REMEDY
Clean or replace parts.
Polish face of the cylinder or replace and
grease again.
Increase air pressure and make some trial
blows. Then reduce air pressure immedi-
ately.
Eliminate the obstruction (see 6). Use pro-
per KMR strips.
Apply tool more firmly.
Replace damaged parts.
Turn penetration setting to +, see 5.
Clean the interior pieces, grease the coun-
ter surfaces of the O-rings and the surface
of the cylinder. Check the lubricator.
Adjust to correct air pressure (min. 5 bar /
0.5 MPa).
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.
Replace damaged part and apply grease to
the counter surfaces.
Eliminate the jamming cause.
Have tool checked by service workshop.
