6. Hold the pusher firmly in one hand, with the other
hand, slightly stretch the spring, bend slightly, and
hook the spring onto the hook in the magazine cover
slot (
Fig. 14
). be careful not to over stretch the
spring.
7. Now one end of the spring is connected to the hook
in the magazine cover slot (
Fig. 15-(1)
) and the other
end goes around the tension roller and hooked on to
the pusher (
Fig. 15-(2)
).
Slide the magazine cover on the stapler while
pressing the magazine latch (
Fig. 9
)
Replace the bracket and fasten in the screw (
Fig. 8

With use, piston may break or
bend. Broken piston often damages
the bumper. Both need to be
replaced. See table below for the
parts stock numbers for
NS10
and
NS11
. Order Lubricant Syringe
(
AS65
) also.
AS65
will be used in the
following steps.
1. Unscrew the four bolts as shown in
Fig. 16
.
2. Remove the bolts (
1
) and exhaust cap (
2
). Carefully
remove the entire cylinder cover assembly (
3
), so the
parts do not fall apart. If the parts fall apart, see the
diagram in Step 9 to reassemble. Some staplers may
have a collar (page 8.
Fig. 22
). Pull it out. Not all
staplers have this part. Do not be concerned if your
stapler does not have one.
