WARNING
To reduce the risk of serious bodily injury, always
follow the Pressure Relief Procedure on page 21
whenever you shut off the pump, when checking or
servicing any part of the dispensing system, when
installing, cleaning or changing fluid tips, and
whenever you stop dispensing.
WARNING
Never operate the pump with the air motor plate
removed, to reduce the risk of serious bodily injury,
including amputation, from moving parts inside the
air motor housing.
The chart below is specific to the air motor and pump.
Refer to the other instruction manuals with the system
to troubleshoot individual components.

This chart uses the proportioner
gauges to determine pump mal-
functions.
Faulty manifold check valves can
mask pump cylinder problems.
Always keep these valves operat-
ing properly.
Observe the gauge readings dur-
ing the stroke direction indicated
by the bold arrow, and
immediately after closing the
manifold.
