SYSTEM SAFETY DEVICES
Be sure all system safety devices are
operating properly before each use. Do not
remove or modify any part of the system; this
can cause a malfunction and result in serious
bodily injury.
SAFETY LATCH
Whenever you stop manually dispensing, even
for a moment, always set the manual gun
safety latch in the closed or "safe" position,
making the manual dispense gun inoperative.
Failure to set the safety latch can result in
accidental triggering of the dispense gun,
which can result in serious injury.
TRIGGER GUARD
Never operate a spray gun with the trigger
guard removed. This guard helps prevent the
spray gun from triggering accidentally if it is
dropped or bumped.
DIFFUSER (only on spray guns)
The spray gun diffuser breaks up spray and
reduces the risk of fluid injection when the tip
is not installed.
Check diffuser operation
regularly.
Follow
Procedure, then remove the spray tip. Aim the
spray gun into a grounded metal pail, holding
the spray gun firmly to the pail.
lowest possible pressure, trigger the spray
gun. If the fluid emitted is not diffused into an
irregular
stream,
immediately.
TIP GUARD (only on spray guns)
ALWAYS have the tip guard in place on the
spray gun while spraying. The tip guard alerts
you to the fluid injection hazard and helps
reduce, but does not prevent, the risk of
accidentally placing your fingers or any part of
your body close to the spray tip.

PRESSURE RELIEF PROCEDURE
To reduce the risk of serious bodily injury,
including fluid injection, splashing in the eyes
or on the skin, or injury from moving parts,
always follow this procedure whenever you
shut off the pump, when checking or servicing
any part of the spray/dispensing system, when
installing, cleaning or changing tips/nozzles,
and whenever you stop spraying/dispensing.

bleeder valve (required in your system),
having a container ready to catch the
drainage.
8. Leave the drain valve open until you are
ready to spray/dispense again.
If you suspect that the gun/tip/nozzle or hose
is completely clogged, or that pressure has not
been fully relieved after following the steps
