STARTING UP
a. Turn the Pressure Control Knob Clockwise to increase
pressure and counterclockwise to decrease pressure.
b. Always use the lowest pressure necessary to completely
atomize the material.
NOTE: OPERATING THE SPRAYER AT HIGHER
PRESSURE THAN NEEDED, WASTES MATERIAL,
CAUSES EARLY TIP WEAR, AND SHORTENS
SPRAYER LIFE.
PRESSURE CONTROL KNOB is used to
adjust pressure. Turn clockwise (CW) to
increase pressure and counterclockwise
(CCW) to decrease pressure.
PRIME/PRESSURE (PR) RELIEF VALVE is used to
prime pump and to relieve pressure from gun, hose and tip.
1. LEARN THE FUNCTIONS OF THE
CONTROLS.
2. PREPARE THE MATERIAL
a. Prepare the material according to the material
manufacturer's recommendations.
b. Place the suction tube into the material container.
3. STARTING THE SPRAYER
a. Prime/PR Valve must be "OPEN" in the priming
position.
b. When you have ensured that the gun safety latch is
engaged, attach tip and safety guard.
c. Turn the engine ON/OFF switch to the "ON"
position. Pull rope vigorously until engine starts.
d. Turn Pressure Control Knob clockwise to prime the
pump.
e. After the pump is primed, turn Prime/PR Valve to the
"Closed" position.
f. Turn Pressure Control Knob to the desired spray
pressure.
g. Disengage the gun safety latch and you are ready to
spray.
4. ADJUSTING THE PRESSURE
FOLLOW THE "PRESSURE RELIEF PROCEDURE".
To reduce the risk of injection, never hold your hand, body,
fingers or hand in a rag in front of the spray tip when cleaning
or checking for a cleared tip. Always point the gun toward the
ground or into a waste container when checking to see if the
tip is cleared or when using a self-cleaning tip.
When you spray into the paint bucket, always use the
lowest spray pressure and maintain firm metal to metal contact
between gun and container.
To stop the unit in an emergency, turn the engine off. Then
relieve the fluid pressure in the pump and hose as instructed
in the Pressure Relief Procedure.
a. Whenever you stop spraying, even for a short break,
follow the "Pressure Relief Procedure".
b. Clean the tip & gun as recommended in the seperate
Gun Manual supplied with the gun.
c. Flush the sprayer at the end of each work day, if the
material you are spraying is water-based, or if it could
harden in the sprayer overnight. See "Flushing". Use a
compatible solvent to flush, then fill the pump and hoses
with an oil based solvent such as mineral spirits.
d. For long term shutdown or storage, refer to the
"Flushing" section of this manual.
5. WHEN SHUTTING OFF THE SPRAYER
Be sure to relieve pressure in the pump after filling with
Airlessco Pump Conditioner.
AVOIDING TIP CLOGS
There is an easy way to keep the outside of the tip clean from
material build up:
Every time you stop spraying, for even a minute, lock the gun
and submerge it into a small bucket of thinner suitable for the
material sprayed.
Thinner will dissolve the buildup of paint on the outside of tip,
tip guard and gun much more effectively if the paint doesn't
have time to dry out completely.
(Prime/PR Valve) Used to relieve pressure
from gun, hose & tip and to primethe unit
when in OPEN position. (It is in open
positionwhen there is a wider gap between
valve handle and cam body.)
When in CLOSED position,there is only
a very slight gap between handle & body.
When closed the system is pressurized.
Handle as a loaded firearm!
c. If more coverage is needed, use a larger tip rather than
increasing the pressure.
d. Check the spray pattern. The tip size and angle
determines the pattern width and flow rate.
