To measure stroke of tool with stall-
nut threaded onto piston:
1. Disconnect tool from airline -- remove nose
from tool.
2
With piston fully forward (end of RETURN
stroke), bottom the stall-nut on piston. Back
stall-nut off five (5) turns.
3. Cycle tool and hold trigger depressed - -
this keeps piston fully to the rear and at end
of PULL stroke. Thread stall-nut back onto
piston until it contacts stop.
4. Release trigger. Stall-nut wilI move forward
with piston. See
FIGURE 4
and measure “X”
dimension. This is the tools stroke.
5. If stroke is less than .812, refer to appropri-
ate previous section. Follow filling and top-
ping off instructions
To measure stroke of tool without
stall-nut:
1. Disconnect tool from airline - - remove nose
from tool.
2. With piston fully forward (end of RETURN
stroke), measure and record “X” dimension - -
see
FIGURE 4.1
.
3. Hold trigger depressed. Piston is now fully to
the rear and at end of PULL stroke. Measure
and record “Y” dimension.
4. Subtract “X” dimension from “Y” dimension.
5. If stroke is less than .812, refer to appropriate
