OPERATION
FLOW CONTROL KNOB
The flow control knob (#18) regulates the
amount of liquid that can be sprayed. Turning
the flow knob clockwise increases the flow of
liquid. Turning the knob counter anti-clockwise
Decreases the flow of liquid.
Tip:
Always test the spray pattern on scrap
cardboard or similar material first. Begin with
flow control knob on the highest flow setting. If
less flow is desired, dial the flow control knob
anti-clockwise to decrease the flow of liquid.
Heavier, thicker materials should be sprayed
with the flow control knob on high flow setting.
Thinner materials should be sprayed with the
flow control knob on a low flow setting.
Developing the proper spraying
technique
- Practice spraying on a piece of scrap material
such as cardboard to test your spray pattern and
become familiar with the flow control feature of
the sprayer.
- Ensure surface to be sprayed is free of dust,
dirt, and grease.
- Ensure spray area is clean and free of dust
that could be blown onto newly sprayed
surfaces.
- Cover any areas not intended to be sprayed.
- Always spray from a minimum of 50mm to a
maximum of 300mm.
- 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.
- To get an even spray distribution, always keep
your arm at the same distance from the
surface you are spraying and avoid moving your
wrist.
- Maintain smooth and consistent speed which will
help avoid inconsistencies. Begin spraying
after the pass has begun and release trigger before
stopping the pass.
- 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 clockwise increases the flow of
liquid. Turning the knob anti-clockwise decreases
the flow of liquid. If runs or drips do
occur, have a dry paint brush on hand to smooth
them out.
