f) Adjust the total length of the assembly to 66 ± 0.1mm, and tighten the lock screw on the
Control Knob. (Figure 7-12)
g) Push the assembly into the body of the tool, and reverse the above procedure to
reassemble all parts.
h) Loosen the lock screw on the Control Nut and turn the Control Knob clockwise until the
Control Nut stops at the end of its movement, and then tighten the lock screw (Figure
7-13).
i) Set a POP Nut without work piece, and check the stroke. If the stroke is 1.3mm or less, it is
normal (Figure 7-14).
Note: When stroke is over (1.3 mm or more), check the assembly length (proper length:
66 ± 0.1), and readjust.
For all other issues - refer to the “Troubleshooting" section.
4. OIL RECHARGING.
If the stroke gets too short due to a lack of hydraulic oil (if a proper setting stroke is not
possible, even after stroke adjustment), follow the procedure below to recharge the hydraulic
oil.
Note: If the stroke is still inadequate after recharging the oil, the hydraulic seals may need to
be replaced. Contact your distributor for tool repair.
Procedure
a) Disconnect the air supply.
b) Set the position of the Control Nut to approximately 10 mm. (Refer to "Adjustment of
stroke")
Note: If Control Nut is not set to around 10 mm, the T Valve and Control Nut could break.
Note: Don't loosen the lock screw of the Control Knob as this would disturb the stroke
(Figure 7-14).
