Mix Tank Volume
Don’t
let the mix tank run dry
. When the tank is empty
,
the pump demands more power as it tries to suck in
some fluid. This causes the pump to run too fast,
which can seriously damage the pump.
Stop the Pump at the Bottom of Its Stroke
WARNING
To
reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure
on page 12.
Whenever you stop the pump for any reason, relieve
the pressure. Stop the pump on the downstroke,
before the air motor changes over
. If the pump is
stopped on the upstroke a pressure relief seat causes
the piston to creep until it reaches the up position.
Following the
Pressure Relief Procedure
helps stop
the pump at the bottom of its stroke.
CAUTION
Failure to stop the pump at the bottom of its stroke
allows fluid to dry on the piston rod, which can cause
damage to the throat packings when the pump is
restarted.
