Warnings
Know all hazards before operating sprayer!
Equipment Misuse Hazard: Equipment misuse
can cause the equipment to rupture or malfunction
and result in serious injury.
Before operating equipment, read all instruction
manuals, tags, and labels.
Check equipment daily. Repair or replace worn
or damaged parts immediately.
Do not exceed maximum working pressure (WPM) of the lowest–rated
system component: 45 psi (3.1 bar, 310 kPa).
Use fluids and solvents that are compatible with the equipment wetted
parts. See Specifications on page 24 for this information.
Wear hearing protection when operating this equipment.
Do not “blow back” fluid; this is not an air spray system
Follow Pressure Relief before cleaning, checking or servicing the
equipment.
TOXIC FLUID HAZARD: Hazardous fluid or toxic
fumes can cause serious injury or death if splashed
in eyes eyes or on skin, inhaled, or swallowed.
Know specific hazards of fluid you are
using and take protective measures as
recommended by the fluid and solvent
manufacturer.
Fire and explosion hazard: Solvent and paint
fumes can ignite or explode.
Sprayers generate sparks. Keep sprayer at least
20 feet (6 m) from explosive vapors.
Use in an extremely well ventilated area.
Eliminate all ignition sources; such as pilot lights,
cigarettes and static arcs from plastic drop cloths.
Do not plug or unplug power cords or turn lights
on or off in spray area.
Ground Sprayer, object being sprayed, paint and
solvent pails.
Do not use 1,1,1-trichloroethane, methylene chlo-
ride, other halogenated hydrocarbon solvents or
fluids containing such solvents in pressurized alu-
minum equipment. Such use could result in a
chemical reaction, with the possibility of explosion.

Setup
Connect Fluid and Air Supply
The HVLP compressor/cart provides the air supply
for remote pressure pots.
The circled letters (page 11) indicate hose line
connections.
1. Connect gun air supply hose (A) between turbine
air outlet (B) and gun air inlet (C). DO NOT use
wrench to tighten connections; hand tighten only.
NOTE: The 4900 turbine uses a quick connector
at the air outlet (B). A wrench is not required to
connect air hose (A).
2. If using spray gun cup (D):
Connect cup to gun fluid inlet (E).
If using accessory remote pressure pot (F):
Connect fluid supply hose (G) between remote
pressure pot fluid outlet (H) and gun fluid inlet (E).
Connect pressure pot air hose (J) between pres-
sure pot air regulator inlet (K) and cart compressor
air outlet (L).

HVLP Compressor/Cart

12 309244
Setup
1. Turn compressor on to warm up a few minutes
before you start spraying.
Turn compressor off when not used for an extended
period of time. The compressor does not shut off auto-
matically.
2. Be sure compressor filter (9) is clean before operating.

Maintenance
Daily
Check cart daily for cleanliness.
Compressor system is lifetime lubricated. The only
maintenance required is filter cleaning and replace-
ment.
Compressor filter must be clean at all times to provide
sufficient air flow to cool motor and sufficient pressur-
ized air to remote pressure pot.
WARNING
To avoid damage to the compressor and possible
electric shock, never install a damp filter in the
compressor.
CAUTION
Dust and dirt can accumulate during use and cause
equipment damage. Do not operate the compressor
without the filter installed.

14 309244
Maintenance
power switch:
1. Turn turbine and compressor OFF.
2. Unplug turbine from power source.

4. Clean or replace filter as follows:
a. Brush accumulated paint and dirt from
surface of foam filter.
b. Rinse filter in water with mild detergent.
Blow dry.
c. Replace filter if paint is caked on.
Weekly
Check hoses for cracks, leaks, and holes.
Replace as necessary.

16 309244
Troubleshooting
PROBLEM CAUSE SOLUTION
No fluid delivery No material, no remote container
pressurization, hose or pickup tube
clogged
Check container for material.
Check for leaks at the container gasket
(2-quart pressure pot cover or
21/2-gallon pressure pot wing nuts).
Tighten wing nuts if loose.
Check for air flow from male quick
disconnect at compressor outlet
(approx. 1/4 CFM –233452; 1/2 CFM –
233449).
Turn pressure regulator clockwise.
Look for pressure on gauge. (If no
pressure on gauge, check air line and
fittings).
Check hole in 21/2-gallon pot cover
under regulator or in 2-quart pot cover
at needle valve.
Clean if necessary.
Check for obstructions or kinks in
hoses and fittings.
Check if fluid pickup tube is unplugged.
Tighten.
Blow out and clear material hose.
