Adjusting
the
Pressure
a.
Turn the pressure control knob clockwise
to
in-
crease and
counterclockwise
to
decrease
pressure. Tighten the knob locknut
to
set.
b. Always use the lowest pressure necessary
to
completely atomize the fluid.
-------CAUTION
-----
.......
Operating the sprayer at a higher pressure than
needed wastes fluid, causes early tip wear, and
shortens sprayer life.
c.
If
more coverage is needed,
use
a larger tip
rather than increasing the pressure.
d. Check the spray pattern. The tip
size
and angle
determine the pattern width and
flow
rate.
Refer
to
the separate instruction manual receiv-
ed
with
your gun.
-------CAUTION
-----
....
The engine throttle
has
been set and locked at
2800 RPM. The sprayer warranty will
be
voided
and the
hydraulic pump life shortened
if
this ad-
justment
is
changed.

Cleaning
a
Clogged
Tip
---~-.-..;WARNING------
To reduce the risk
of
a fluid injection injury,
NEVER
hold your hand, body, or rag in front
of
the spray tip when cleaning or checking
for
a
cleared tip. Always point the gun toward the
ground or into a waste container when checking
to
see
if
the tip was cleared or when using a self-
clearing tip.
a.
Follow the Pressure
Relief
Procedure
Warn-
ing
on page

b. Clean the front
of
the tip frequently during the
day
to
keep fluid from building up and clogging
the tip. To clean, and
to
clear a tip
if
it clogs
while
spraying, refer
to
your separate gun or
nozzle instruction
manual for the proper pro-
cedure.

Use a compatible sol-
vent
to
flush, then fill the pump and hoses with
an
oil-based solvent such
as
mineral spirits
to
help prevent pump corrosion. Be
sure
to
relieve
pressure
in
the
pump
after
filling
with
mineral
spiritsl
