The transition time from stroke
to unscrewing slows.
Open the manostat and pull the piston out (
G
),
grease it and reassemble it.
Air leaks from muffler (
T
).
Check the two o-rings (
O4
) and o-ring (
21
)
which could be worn or broken.
MOTOR screwing
When the rotating pin (
6
) is broken and you replace it, it may happen that the motor rotates
continuously, which means that the shaft (
13
) is too long; in this case it will have to be shortened
by a few tenths to obtain the closure of the ball (
14
).
Unlike the situation above, the shaft is too short and it has to be replaced with a new one, fitting it
without end float, with the air on, in order to obtain the closure of the ball
(
14
).
Quick kit assembly.
When assembling the quick kit, with air, make sure to create an axial
space of
1.5mm
between the lock nut and the end of the piston.
Loss of rev. during unscrewing. When you are working intensely there is likely to be a loss of
revolutions in the unscrewing; it is necessary to remove the air hose
and add a few drops of oil in the air hose connection (Ref.
34
) and re-
enter the air by turning the engine with button (
P
) for a couple of
minutes.
Air leaks from air distributor.
In case of loss of air from the air distributor, the plate of the piston is broken.
