WARNING
Use only water-based or oil-based (mineral spirit-type) materials with flash point greater than 100° F
(38° C). Do not use materials which state “FLAMMABLE” on the packaging. For more information about
your material, request MSDS from distributor or retailer.
Use oil-based material outdoors or in a well-ventilated indoor area with a flow of fresh air.
Spraying certain materials may cause static build-up in the sprayer that can result in static shock to
the user. If this occurs, first ensure the material has a flash point greater than 100° F (38° C) and does not
state that it is FLAMMABLE anywhere on the package. If still feeling a static shock, the material likely con-
tains a non-mineral spirits fluid such as, but not limited to, xylene, toluene, or naphtha, which can build up
static. Switch to an alternative material.

Setup
Installing Suction Tube
Aim the inlet of the suction tube at the front of the material
cup (towards Spray Tip/Guard Assembly) during installa-
tion.
Spraying Stains or Clear Coats
(Fine-Finish Optimizer)
The Fine-Finish Optimizer should be installed and used
when spraying thin material such as stain or clear coats.
The Fine-Finish Optimizer restricts the material flow
resulting in a finer quality finish.
Installation
1. Remove material cup and suction tube.
2. Remove the cleaning tool before installing the
Fine-finish Optimizer into the sprayer.
3. Push Fine-Finish Optimizer into pump inlet until
completely engaged and re-install suction tube.
Cleanup/Storage
Be sure to remove and clean the Fine-Finish Optimizer
immediately after use. Store the Fine-Finish Optimizer
on the Storage/cleaning Tool supplied to keep the hole
clear of dried material.
Use only water-based or oil-based (mineral
spirit-type) materials with flash point greater than
100° F (38° C). Do not use materials which state
“FLAMMABLE” on the packaging. For more informa-
tion about your material, request MSDS from distribu-
tor or retailer.
Spraying certain materials may cause static
build-up in the sprayer that can result in static
shock to the user. If this occurs, first ensure the mate-
rial has a flash point greater than 100° F (38° C) and
does not state that it is FLAMMABLE anywhere on the
package. If still feeling a static shock, the material likely
contains a non-mineral spirits fluid such as, but not lim-
ited to, xylene, toluene, or naphtha, which can build up
static. Switch to an alternative material.
Use oil-based material outdoors or in a well-ventilated
indoor area with a flow of fresh air.
Keep spray area well-ventilated. Keep a good supply
of fresh air moving through the area.
NOTICE
Your sprayer is NOT compatible with harsh cleaners
such as chlorine bleach. Using these cleaners will

Basic Spraying Techniques
12 3A0705B
Basic Spraying Techniques
NOTE: Use a piece of scrap cardboard to practice these
basic spraying techniques before you begin spraying the
surface. Anything you don’t want painted that is in
the area of your spraying surface should be covered
or removed.
Hold sprayer at least 25 cm (10 in.) from surface and
adjust accordingly to achieve desired results. Aim
sprayer straight at surface. Tilting sprayer to direct spray
angle causes an uneven finish.
Flex your wrist while moving your arm to keep the
sprayer pointed straight. Tilting the sprayer or spraying
at an angle causes an uneven finish.
NOTE: How fast you move the sprayer will affect spray
application. If material is pulsating, you are moving too fast.
If material drips, you are moving too slow. See Trouble-
shooting, page 18.
Triggering Sprayer
Pull trigger after starting stroke. Release trigger before end
of stroke. Sprayer must be moving when trigger is pulled
and released.
Aiming Sprayer
Aim tip of sprayer at bottom edge of previous stroke, over-
lapping each stroke by half.
