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 thor-
oughly familiar with the controls.
To reduce the risk of injury:
1. Do not spray acids, corrosive mate-
rials, 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 environ-
ment. Do not aim the spray gun at
any dust or debris.
4. Do not operate or spray near chil-
dren. Keep children, pets, and visi-
tors 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 influ-
ence 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 approxi-
mately 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 perpen-
dicular to the surface (See Figures 1
& 2). Do not fan the gun. Fanning
the gun will cause excessive over-
spray and uneven coverage (See
Figure 2).
3. Start moving the gun before triggering
To get a smooth overlap and pre-
vent 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 differ-
ent 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 air-
less 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 trig-
ger 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 accord-
ing to the manufacturer’s instruc-
tions.
