NOTE: Turning the pressure up higher than needed to
atomize the paint will cause premature tip wear and
additional overspray.
b. Check for proper line width and position. If adjustment to the
position of the spray gun is required, refer to the “Setup” procedure
earlier in this section.
22. Make sure that the spray gun completely shuts off when the
gun trigger is released. If adjustment to the trigger tension
is required, refer to the “Adjusting the Trigger Tension”
procedure.
Operating the Front caster
The front caster on the cart is designed to track the sprayer in either
a straight line or allow free motion. Standing behind the sprayer, the
trigger on the left handle of the cart controls the operation of the
front caster.
1. To lock the front caster in the straight line position, squeeze
then release the caster trigger and move the sprayer forward.
2. To allow free motion of the front caster, squeeze and hold the
caster trigger.
NOTE: To lock the front caster in free motion mode,
squeeze and hold the caster trigger and then push
in the locking button on the side of the trigger.
Once the locking button is pushed in, the caster
trigger can be released. To release the locking pin,
squeeze the caster trigger.
Pressure Relief Procedure
Be sure to follow the Pressure Relief Procedure when
shutting the unit down for any purpose, including
servicing or adjusting any part of the spray system,
changing or cleaning spray nozzles, or preparing for
cleanup.
1. Lock the gun by turning the gun trigger lock to the locked
position.
2. Turn off the sprayer by moving the pump ON/OFF switch to
the OFF position.
3. Turn off the engine by moving the engine ON/OFF switch to
the OFF position.
4. Turn the pressure control knob counterclockwise to its lowest
setting.
5. Unlock the gun by turning the gun trigger lock to the
unlocked position.
6. Hold the metal part of the gun firmly to the
side of a metal container to ground the gun
and avoid a build up of static electricity.
7. Trigger the gun to remove any pressure that
may still be in the hose.
8. Lock the gun by turning the gun trigger lock to the locked
position.
9. Move the PRIME/SPRAY valve to the PRIME position.
cleanup
Special cleanup instructions for use with flammable
solvents:
• Always flush spray gun preferably outside and at least one
hose length from spray pump.
• If collecting flushed solvents in a one gallon metal container,
place it into an empty five gallon container, then flush
solvents.
• Area must be free of flammable vapors.
• Follow all cleanup instructions.
ImPORTANT: The sprayer, hose, and gun should be cleaned
thoroughly after daily use. Failure to do so permits material to
build up, seriously affecting the performance of the unit.
Always spray at minimum pressure with the gun
nozzle tip removed when using mineral spirits or any
other solvent to clean the sprayer, hose, or gun. Static
electricity buildup may result in a fire or explosion in
the presence of flammable vapors.
1. Follow the “Pressure Relief Procedure” found in the Operation
section of this manual.
2. Remove the gun tip and tip guard and clean with a brush
using the appropriate solvent.
3. Place the siphon tube into a container of the appropriate
solvent (refer to recommendations of the material
manufacturer). An example of the appropriate solvent is
water for latex paint.
4. Place the return hose into a metal waste container.
5. Move the PRIME/SPRAY valve to its PRIME position.
6. Move the engine ON/OFF switch to the ON position and start
the engine.
7. Turn on the sprayer by moving the sprayer ON/OFF switch to
the ON position.
8. Slowly turn the pressure control knob clockwise to increase
the pressure until fluid starts to come out of the return hose.
9. Allow the solvent to circulate through the sprayer and
flush the paint out of the return hose into the metal waste
container.
10. Turn the pressure control knob fully counterclockwise to its
lowest setting.
11. Turn off the sprayer by moving the ON/OFF switch to the OFF
position.
12. Move the PRIME/SPRAY valve to its SPRAY position.
13. Turn on the sprayer.
14. Turn the pressure control knob slowly clockwise to increase
pressure.
Ground the gun by holding it against
the edge of the metal container
while flushing. Failure to do so may
lead to a static electric discharge,
which may cause a fire.
15. Trigger the gun into the metal waste container until the paint
is flushed out of the hose and solvent is coming out of the
gun.
16. Continue to trigger the spray gun into the waste container
until the solvent coming out of the gun is clean.
NOTE: For long-term or cold weather storage, pump
mineral sprits through the entire system.
17. Follow the “Pressure Relief Procedure” found in the Operation
section of this manual.
18. Store the sprayer in a clean, dry area.
ImPORTANT: Do not store the unit under pressure.
