9.2.3
Stroke Adjustment (Continued)
The relationship between the blades and the finger loop position can be adjusted so the point where
the blades just close fully can be put in some preferred position. (Usually where the finger loop is
just about fully inward. Special blades may prefer other positions).
Verify that the smoothness is adjusted properly before proceeding.
Disconnect the air line.
Remove the blade set (reference Section 8.3.2).
Open the cover and using a 9/16 inch open-end wrench, loosen the control valve lock nut about 3
turns. Then close cover. (
NOTE:
On the AirShirz® Magnum, it is necessary to remove the
cover).
Connect the air line and disengage the blade latch.
Observe the power cylinder rod position while working the finger loop fully in and out. The rod
should reach the end of its stroke, both ways, before the finger loop reaches the limits of its stroke.
See Figure #30A.
