Step 6: Attach the valve. Put the new valve on the pump head to replace the old one removed in Step 2. As
shown in the pictures below, make sure that the valve is fully pushed in on both the suction and the exhaust
sides. Also ensure that there is no gap between the valve and the pump head. In addition, align the position of
the valve so its sides do not touch the inner wall of the dent on the pump head.

Step 7: Using the torque screwdriver
(0.25-0.30 Nm) with the tri-wing bit attached,
fasten the valve aligned in Step 6 with the
tri-wing screw (M3×4). Apply the Loctite 262
or Loctite 263 onto 2-4 threads from the screw
tip for the tri-wing screw.
After tightening the tri-wing screw, re-check
the alignment of the valve.
*Be careful when applying Loctite, as too
much or too little can cause damage.
*Be sure to always follow the appropriate
tightening torque. Failure to do so can lead to
product damage.
