GROUNDING SAFETY
Check your local electrical code for detailed grounding
instructions for your area and type of equipment and be
sure to ground all of this spray equipment as the
following.
1 Pump : Use a ground wire and ground to a good
source such as the building ground source, or drive
a steel spike into the ground and attach the ground
wire to it.
2 Fluid hoses : Use only grounded hoses to a maxi-
mum of 500 FT (150M)
3 Spray Gun : Connect to a properly grounded fluid
hose and pump.
5 Object being sprayed & Fluid supply tank : All
sources should be grounded.
6 Solvent pail : Use only metal pails not plastic or
use the pail on a non conductive surface, such as
card board or plastic sheeting .
PREPARING PAINT FOR USE.
These are probably the most important steps
toward trouble-free spray painting.
•
Prepare the paint or other coatings according to the
manufacturer’s instructions.
•
If the paint has been opened before, the product
should checked to make certain that it has not
skinned over .
•
Stir paint thoroughly to dissolve hard pigments.
•
Strain the paint through a fine nylon mesh bag
(available at most paint dealers) to remove
particles that may clog filters, or spray tip.
•
Follow the paint manufacturer’s recommendation
on thinning the material to be sprayed.
•
Be careful not to add too much solvent, over
thinning paint makes the coating hard to control
and reduces its coverage .
AIRLESS – SPRAY TECHNIQUE
Good airless-spray technique is much like conventional
air spray, except that you hold the gun further from
work surface, you get more coating thickness, which
results in less pattern overlapping, and you use more
positive action when triggering gun.
Hold the gun 10-12 in from the work, the distance
varies with the covering ability of the paint, type of
surface to be sprayed, and the spray pattern.

•
Install the correct spray hose and spray tips to suit
the type of application.
•
All fluid hoses must be properly sized and pressure
rated for this equipment.
•
Use only grounded fluid hoses.
•
Pressure regulator - This controls pump pres sure
and outlet pressure by adjusting the adjustment
knob to the pump.
•
Hydraulic shut off valve - This lever type valve
shuts off fluid pressure from hydraulic pump.
•
Suction tube filter - Removes harmful and course
materials from entering pump.
•
Filter manifold - Removes and filters out the impu-
rities from the paint before reaching the spray tip.
•
Prime valve - Releases fluid pressure from the
pump, hoses and guns. Turn counter clockwise to
open and clockwise to close.
•
Spray Gun Make sure that gun is in good operating
condition.
MOVING PARTS SAFETY WARNING
•
Moving parts can cause to pinch or seriously
injure your fingers or other body parts.
•
Keep clear of moving parts when starting
or operating the pump and be sure to follow
the “Pressure Relief Procedure” to prevent
the pump starting accidentally.
