3. Reassembly of the power assembly
Reverse the disassembly procedure to reassemble. Note the following points:
• Use the specified tightening torques. (See page 31.)
• Protect the sealing parts (e.g., O-rings, X-rings, valve core, etc.) against contaminants and scratches
during reassembly.
• Always use brand-new seal lock bolts. Never reuse the old bolts.
• Use the alignment marks (made before disassembly) for precise positioning when mounting the Chamber
Base Ass’y
[11]
on the Cylinder
[5]
.
• Slowly tighten the four Nylock Bolts M6
[12]
to fasten the Chamber Base Ass’y
[11]
and Chamber Cover
[4]
. Be careful not to pinch and damage the O-ring (I.D 94.5)
[7]
.

[25]
with about 1 g of Molub-Alloy 777-1 grease by hand before reassembly.
• Mount the Pin Wheel
[28]
to the Position Detector
[23]
so that the end surface side of Pin (A)
[34]
is
aligned with the notch of the Position Detector
[23]
as shown in Fig. 21.
NOTE: If the Position Detector [23] is not precisely located, an error (causing the orange LED of
the battery indicator to blink) may occur.
• Remove dust from between the Pin Wheel
