a shorter amount of time.
f The lower speed level allows you to get closer to your
work with less overspray. Low setting works well with
lighter bodied or more free flowing paints like stains
and sealers.
f More heavy bodied paints, like water based latex, will
need setting number 2.
f Use the speed control setting in conjuction with the
flow control knob and test for what works best with
your material being sprayed. Set the flow control to a
lower or medium setting (1-5) when on speed setting
1. Set the flow control to medium or higher setting
(5-9) when on speed setting 2.
FLOW CONTROL KNOB (FIG. I)
The flow control knob regulates the amount of liquid that
can be sprayed.
f Select low (1), medium (5) or high (9) on the flow
control knob.
Tip: Always test the spray pattern on scrap cardboard or
similar material first. Begin with flow control knob on the
highest flow setting. Heavier, thicker materials should be
sprayed on the higher setting closer to #9. Thinner materials
should be sprayed on the lower setting closer to #1.

OPERATION

ON / OFF TRIGGER (FIG. J)
The sprayer is turned on and off by the trigger.
f To turn the sprayer on, squeeze the trigger.
f To turn the sprayer off, release the trigger.
Warning! Risk of injury. Never point the sprayer at any
part of the body. Never pull the trigger while adjusting the
spray setting.
PRIMING WITH THE DIRECT TO CAN HOSE
(BDPS600 only)
f The time needed to prime will vary from 30 seconds
to 3 minutes depending upon the thickness of the
material you are spraying. When the sprayer is
priming or sucking up the paint on the initial use, it
will produce a loud noise, this is normal. When the
sprayer is primed and painting, the noise will lessen.
f If your sprayer is properly cleaned and oiled and it
takes longer than three minutes to prime, your piston
and/or pump housing may be worn and will need to be
replaced before using your direct to can hose.
f Using the direct to can hose will decrease the material
flow, so it will take longer to apply the same amount of
material to the surface being sprayed.
f A 75% duty cycle is recommended when using the
direct to can hose. For example, trigger the sprayer
for 15 seconds, and then allow the sprayer to remain
idle for 5 seconds.
f If you are using the direct to can hose, you will need to
prime the sprayer by K removing air from the system.
To prime:
1. Make sure the sprayer is plugged in, and turn the flow
control knob counterclockwise to maximum (Fig.K)
2. Hold the sprayer below the level of the paint. This will
speed up the priming (Fig. L).
3. Aim the sprayer at a piece of scrap wood or cardboard.
Squeeze the trigger and hold until all air is out of the
system and material is flowing freely out of the
sprayer tip. This could take up to three minutes.
Important! The end of the direct to can hose must
remain completely submerged in the material. If it is not
completely submerged and air is sucked into the system,
the piston could seize. If the piston seizes, the sound the
sprayer makes will change to a low hum and the sprayer
will quickly become hot to the touch. Never run the sprayer
when the piston is seized. Should this happen, clean the
piston and the pump housing thoroughly using the cleanup
procedures found in this manual.
DEVELOPING THE PROPER
SPRAyING TECHNIQUE
f Practice spraying on a piece of scrap material such
as cardboard to test your spray pattern and become
familiar with the speed settings flow control features
of the sprayer.
f Ensure surface to be sprayed is free of dust, dirt, and
grease.
f Ensure spray area is clean and free of dust that could
be blown onto newly sprayed surfaces.
f Cover any areas not intended to be sprayed.
f Always spray from a minimum of 1 inch (25mm) to a
maximum of 14 inches (355mm) (Fig M). Optimal is
usually around 10 inches or use a paint stir stick as a
reference.
f A commonly used method for spraying a large surface
is the "crisscross" pattern. This is done by spraying in
horizontal strips and then crossing over these strips
with vertical strips.
f To get an even spray distribution, always keep your
arm at the same distance (Fig. M) from the surface
you are spraying and avoid moving your wrist (Fig. M1).
f Maintain smooth and consistent speed which will help
avoid inconsistencies. Begin spraying after the pass
has begun and release trigger before stopping the
pass.
f Avoid spraying too heavily in any one area. Several
lighter coats are better than one heavy coat which can
lead to running and dripping. Remember that the flow
control knob regulates the amount of liquid that can
be sprayed. Turning the flow knob counterclockwise
