Service (continued)
Check the reservoir pressure gauge prior to
performing any maintenance to ensure that the
pressure is zero (0). To confirm this on EFD tanks:
slide the shutoff valve on the air hose away from
the tank, then open the pressure relief valve on the
tank.
CAUTION
To change the diaphragm:
1.
Remove the fluid body.
2.
Place the 1/8" flat tip screwdriver (supplied)
through the center hole in the air cylinder cap.
See above. Engage the slot in the end of the
piston shaft. While holding the screwdriver,
unscrew the diaphragm counterclockwise.
3.
While holding the screwdriver, carefully
thread on the new diaphragm. Be careful not
to strip or cross-thread the diaphragm thread.
Finger-tighten with medium pressure until the
diaphragm bottoms against the shoulder on
the piston rod.
4.
Before installing the fluid body, determine the
operator’s desired position of the fluid inlet
fitting. Use the screwdriver inserted through
the hole in the air cylinder cap to align the
holes on the diaphragm with the appropriate
holes in the air cylinder body. Holding the
air cylinder body, rotate the piston shaft
clockwise using the screwdriver until the
appropriate holes line up.
5.
Reinstall the fluid body. Tighten the retainer
screws 1/2 turn after they contact the fluid
body. Proper torque is 0.75 N·m (7 in.-lb).
