Always have the tip guard in place while spraying.
Even after you shut off the electric motor, there is high
pressure in the pump, hose and gun, until you release it.
A/ways release pressure when you are done spraying and
before servicing, cleaning, or removal of any parts. To release
pressure, shut off the unit, engage trigger safety and open
drain valve. Have a container ready to catch draining material.
DO NOT try to"blow back" paint; this is NOT an air spray unit.
NEVER leave a pressurized unit unattended.
When spray gun is not actually spraying, always set gun
safety latch in closed, or "SAFE" position, making the trigger
inoperative. DO NOT REMOVE OR MODIFY any part of
spray gun. Check diffuser operation by using the lowest
possible spray pressure without a spray tip. Trigger gun into a
waste container - fluid emitted should be diffused into an
irregular stream.

Be sure that all accessory hoses, swivels, etc. used with this
unit can withstand the high pressure developed. This unit
develops3000 PSI (210 bar) fluid pressure.
Before each use, check entire hose for cuts, leaks, abrasion or
bulging of cover or damage of movement of couplings. If any
of these conditions exist, replace the hose immediately. Never
use tape or any device to attempt to mend the hose.

Tighten all fluid connections securely before each use.
PREVENT STATIC SPARKING,.,

The high velocity flow of material through equlprnent may
develop static electricity. Be sure that the equipment being
used, and the object being sprayed, are properly grounded to
prevent static discharge and sparks which could cause fire or
explosion.
Use only conductive or grounded fluid hoses for airless
applications. Be sure that gun is grounded through hose
connections.
Once each week, check electrical resistance of hose (when
using multiple hose assemblies, check overall resistancel.
Overall (end to end) resistance of unpressurized hose must not
exceed 29 megohms (max.) for any coup!ed length or com-
bination of hose lengths. If hose exceeds these limits, replace
it immediately.
Never exceed 500 ft (150 m) overall combined hose length
This unit has a 3-prong grounding plug to protecr you frorn
electric shock. Be sure to plug the unit into a properly
grounded outlet that will accept the 3-prong plug. Do not
remove the third prong.
The green ground wire of electric cord is connected to the unit
chassis and motor frame and the other two wires are
connected to the switch motor for grounding continuity.
Plug into an outlet at least 20 ft (6 m) from the area where you
are spraying. If you use an extension cord, it rnust have 3 wires
of at least 12 gauge (2.5 mm2) and should not be over 100 ft
(30.3 ml long.
Use the lowest possible pressure when flushing equipment,
and maintain firm metal to metal contact between gun and a
grounded metal waste container. This reduces the chance of
static sparking.
Follow the coating and solvent manufacturer's safety pre-
cautions and warnings.
