Be very careful in handling the Plunger Spring [56],
as it can become twisted very easily.
To prevent the two O-rings on the outside of the
Valve Bushing [60] from being damaged when
inserted into the body, carefully apply grease to the
body hole and the outer circumference of the O-rings
prior to assembly.
(c) Adjustment of the Pushing Lever [54] (See Fig. 13.)
The Pushing Lever [54] can be adjusted by loosening
the Nut M5 [55] and turning the Safety Bolt [51].
Perform adjustment to a point where the resistance
of Safety Plunger (B) [61] pushing up Plunger (A)
[57] is felt when the pushing lever is raised. At this
point, the lower end of the Tail Cover [31] should be
separated from the lower end of the pushing lever by
6.5 mm 0.5 mm (.256" .020").
