Spray Guns for Airless Paint Sprayers
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.

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.
PreparationAirless 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.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).

Figure 1 - Holding the Spray Gun2.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).

It may be necessary to change spray tips during a paint job. Follow these steps for safe, easy tip changes.
1.Depressurize and turn off unit per manufacturer’s instructions.
2.Engage gun trigger lock.
3.Pull red tip insert
out of spray base and replace with different tip, fully inserting tip into base.
HOW TO ATTACH ROLLERACCESSORY:1.Depressurize and turn off unit per manufacturer’s instructions.
2.Engage gun trigger lock.
3.Remove spray base, tip, seal and washer assembly.
4.Attach roller
accessory
(AL2275
shown) to airless spray gun. If needed
use thread adapter and washer between roller and spray gun as shown.
INTERMITTENT USEIf 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.
