Spraying
Ensure the fill/spray
toggle switch is in the
FILL/OFF position
and that the mud flow
control is turned all
the way in the coun-
terclockwise direction.
Finally, make sure the
air flow control on the gun is turned to the off
position.
Connect the air com-
pressor hose to the
male air inlet on the
pneumatic assembly.
Set the air compressor
to 40 psi and adjust
as desired. DO NOT
EXCEED 120 PSI.
DOING SO COULD RESULT IN SERIOUS
INJURY.
Once the air compres-
sor hose is connected,
put the backpack on.
There are several
adjustments that can
be made to the straps
to ensure a comfort-
able, snug fit. Once the
backpack is in a secure and comfortable posi-
tion, flip the fill/spray toggle switch to SPRAY
and adjust the gun airflow by opening the ball
valve at the base of the gun.
While holding down the
trigger of the gun, begin
adjusting the mud flow.
Simply lift and turn the
mud flow control in a
clockwise direction to
increase flow and turn
counterclockwise to
decrease flow. This may require spraying
some material onto a scrap sheet of material.
Once the desired mud
flow is achieved, lock
the mud flow con-
trol by pushing the
outer portion of the
dial back down. DO
NOT ATTEMPT TO
OVERTIGHTEN THE
KNOB. DOING SO COULD RESULT IN
COMPONENT FAILURE AND SERIOUS
INJURY.
You are now ready to use the ENFORCER™
NOTE: There are several adjustments that
can be made to the Sharpshooter 2.0, the
ENFORCER, and the compressor to get the
texture of spray you desire.
• The more open the trigger; the more
material will be applied with a resulting
coarser pattern.
• The higher the air pressure, the finer the
pattern; the lower the air pressure, the
coarser the pattern.
• The higher the air flow, the finer the
pattern; the lower the air flow, the coarser
the pattern.
• Larger orifice openings will produce a
coarser pattern than will a smaller opening.
• Of the three most popular patterns, orange
peel, knockdown, and popcorn – orange
peel and knockdown are generally applied
to walls while popcorn aggregate is a
ceiling finish.
• The more open the mud flow control on the
ENFORCER™, the more mud that will be
applied.
To apply orange peel: select the second
smallest opening (#6) in the orifice plate, set
the trigger so that the end of the air nozzle
is approximately 1/8" (3.18 mm) from the ori-
fice plate. Air pressure should be 22–30 psi.
Again, before spraying the finished product,
check for the desired texture on a scrap piece
of sheetrock.
To apply knockdown: also referred to as
splatter, change the orifice plate to the middle
opening (.315"/8.0 mm dia.) (#4), set the trig-
ger fully open. The air pressure should be
reduced to 18–25 psi. Again, before spraying
finished product, check for the desired texture
on a scrap piece of sheetrock.
