MEASURING STROKE USING A STALL NUT
1.
Disconnect the tool from the air-line and remove
the nose assembly.
2. Reconnect the tool to the air-line. Press and hold
the trigger to cycle the piston fully to the rear of
the tool (the end of the PULL stroke).
Thread the
stall nut
onto the piston until it contacts the adapter
bushing.
3.
Release the trigger. The stall nut wilI move forward
with the piston. (Figure 6)
4. Measure the
X
dimension. (This is the
tool stroke
.)
If the stroke is less than 0.650 in (
1.65 cm
)
, follow the
steps at the end of the
Fill and Bleed
procedure.
A Stroke Limiter Kit (P/N 126915) is included with the 2014 tool. See

Disconnect the tool from the air-line and remove
the nose assembly.
2. Reconnect the tool to the air-line. Press and hold
the trigger to cycle the piston fully forward (the end
of the RETURN stroke). Measure and record the
Y
dimension. (Figure 7)
3.
Press and hold the trigger; the piston is now fully
to the rear of the tool (the end of the PULL stroke).
Measure and record the
X
dimension. (Figure 8)
4. Subtract
X
from
Y
.
Stroke = Y-X
(This is the
tool stroke
.)
If the stroke is less than 0.650 in (
1.65 cm
), follow the
steps at the end of the
