Put the air piston back inside the cylinder
cup.
A
At that time, the air piston is susceptible to falling
inside the cylinder cup. Carefully press the air
piston straight to the bottom. (10-1)
If the piston inclines, remove it and then press it
again. Do not forcibly press the inclining piston.
(10-2)
Put the air cylinder containing the air piston
together with the cylinder top. Hold them
down while fastening the four tapping
screws.
After all parts have been reassembled but
before the frame head has been re-attached,
hold the tool so that the bleed plug (hexagon
socket head cap screw) is facing directly
upward, and use the accessory hex key
wrench to loosen the bleed plug to drain any
excess oil. After checking that no more oil is
coming out, re-tighten the bleed plug.
A
Be careful when loosening the bleed plug, as the
hydraulic oil may spurt out strongly.
Wipe away any oil outside the tool and clean
up any spilt oil before using the tool.
After checking the jaw case setting position,
install the frame head. (Refer to pages 9.)
