Spray Guns for Airless Paint Sprayers

General Safety Information (Cont.)

NOTE: If gun sprays while in the locked position follow instructions in Maintenance section for trigger lock.

12.Verify that all connections are secure before operating. Do not use pliers to tighten or loosen high pressure connections.

13.Know how to stop your unit and bleed pressure quickly. Be thoroughly familiar with the controls.

To reduce the risk of injury:

1.Do not spray acids, corrosive materials, toxic chemicals, fertilizers, or pesticides. Using these materials could result in death or serious injury.

2.Always wear appropriate gloves, eye protection, and a respirator or mask when painting.

3.Always work in a clean environment. Do not aim the spray gun at any dust or debris.

4.Do not operate or spray near children. Keep children, pets, and visitors away from equipment and work area at all times.

5.Do not over reach or stand on an unstable support. Keep effective footing and balance at all times.

6.Stay alert and watch what you are doing.

7.Do not operate the equipment when fatigued or under the influence of drugs or alcohol.

FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SERIOUS INJURY INCLUDING DEATH.

Preparation

Airless painting systems, unlike most other power tools, require additional care to ensure proper working order.

CONSULT YOUR AIRLESS PAINT SPRAYER OWNER'S MANUAL FOR OPERATING INSTRUCTIONS.
Spraying Instructions

Professional looking results can be obtained by following the spray tips below.

1.Keep the gun perpendicular to the surface.

Always hold the gun perpendicular to the surface with the tip approximately 12” from the surface. If held at an angle (up and down or side to side), paint will build up unevenly, leave the work splotchy, and cause excessive overspray (See Figure 1).

2.Move with a smooth arm stroke

Move the gun at a steady, even pace while keeping the gun perpendicular to the surface (See Figures 1 & 2). Do not fan the gun. Fanning the gun will cause excessive overspray and uneven coverage (See Figure 2).

3.Start moving the gun before triggering

To get a smooth overlap and prevent initial paint buildup, start your stroke movement before pulling the trigger. Release the trigger before stopping at the end of the stroke (See Figure 3).

NOTE: To assure uniform paint coverage, overlap each stroke by 20% - 30% and use two coats with a cross pattern (one coat horizontal, second coat vertical).

INTERMITTENT USE

If you are spraying and decide to stop for several minutes, lock the spray gun trigger and submerge the tip in a container of suitable solvent (See Figure 4). This will prevent paint from hardening in the tiny spray opening and clogging the tip. Be sure to release the pressure in the system and turn the unit off according to the manufacturer’s instructions.
