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.
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).
HOW TO CHANGE SPRAY TIPS:
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 ROLLER
ACCESSORY:
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 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.
