iii.
Check for freedom of movement of the control cable within the remote controls by moving the control crank
handle back and forth approximately one-quarter turn. During this test, take care to avoid cranking the
control cable onto the ground exposing it to dirt and sand. If any resistance is felt during this check, re-
inspect the control conduits for dents or depressions. If dents are not present on the remote control conduits,
the control cable may be rusted stiff somewhere within the control conduits. Do not use remote controls that
do not function properly or exhibit defects described above.
iv.
A final check of the control cable connector and source assembly connector is accomplished by use of a
Model 550 NO GO gauge to check for significant wear on the connectors that would affect safety. Without
using excessive force, check the following four positions (see Figure 13):
1
Ball at the end of the control cable connector must NOT GO into the hole of the gauge.
2
The shank or stem of the control cable connector must NOT GO into the smaller of the two notches located
on the side of the gauge.
3
The width of the gauge must NOT GO into the female slot of the source assembly connector.
4
After a positive connection between the control cable and source assembly connectors has been
accomplished, verify that the larger notch located on the side of the gauge will NOT GO in the gap between
the joined connectors.
Figure 13 – NoGo Gauge Inspection Checks
Replace any components that fail any of the NO GO gauge tests, because a failure indicates
significant wear that could allow safety features of the design to be defeated.
D.
Daily Inspection of the pneumatic actuator and the air pump control
1)
Inspect the actuator to verify all fastening hardware on the actuator body are present and not loose. Remove the
protective cap and inspect the two collar ring pins to ensure they have not rotated and are parallel to each other and
are not bent or excessively worn.
