IMMEDIATELY. Check the entire system for positive

and corrected.
Grounding
To reduce the risk of static sparking, ground the pump and ail
other components used or located in the sprayldispensing
area. CHECK your
electrical code foi detailed grounding
instructions for your area and type of equipmenrand be sure
to ground all
of
these components:
1. Pump: Ground the complete pump as indicated in your
separate instruction manual.
2.
Air and fluid hoses: use only grounded hoses with a max-
imum of 500 feet
combined hose length to en-
sure grounding continuity. Refer to Hose Grounding
,
Continuity.
3.
Air compressor: follow the air compressor manufacturer's
recommendations.
Spray
valve: obtain grounding through
connection to
a
properly grounded fluid hose and pump.
5.
Fluid
Supply Container: according to local code,
6.
Object being sprayed: according to local code.

when flushing
always hold a metal part of the gun firmly to

Safety
Before flushing, be sure the entire system and flushing
are properly grounded. Refer to Groundlng, above. Follow
the Pressure
Procedure on page

and remove the
the lowest possible fluid pressure, and maintain firm
spray
from the
valve. Always use
metal contact between the gunldispensing valve and the pail
during flushing to reduce the risk of fluid injection injury, static
sparking and splashing.
HOSE
SAFETY
High pressure fluid in the hoses can be very dangerous. If the
hose develops
a
leak, split or rupture due to any kind of wear,
damage
or
misuse, the high pressure spray emitted from
it
can
cause a fluid injection injury or other serious bodily injury or
damage.

NEVER use a damaged hose. Before each use, check the en-
tire hose for cuts, leaks, abrasion, bulging cover, or damage or
movement of the hose couplings. If any of these conditions
exist. replace the hose immediately. DO NOT try to recouple

with tape
or
any other device. A
