Cleaning a Clogged Tip
WARNING
To
reduce the risk of serious bodily injury from from
fluid injection:
NEVER operate the spray gun with the tip guard
removed.
DO NOT hold your hand, body
, or a rag in front of
the spray tip when cleaning or checking for a clog.
Always point the gun toward the ground or into a
pail.
DO NOT try to “blow back” paint; this is NOT an air
spray sprayer
.
1.
Clean the front of the tip frequently
. Follow the
Pressure Relief Procedure
, page 1
1, first.
2.
Follow the cleaning instructions given in your
separate gun or spray tip instruction manual.
Shutdown and Care
1. Keep the packing nut/wet-cup (221) 1/3 full of
TSL
(Throat Seal Liquid, supplied) at all times to
help prevent fluid buildup on the piston rod and
premature wear of packings. Follow the
Pressure
Relief Procedure
, page 1
1, before adding TSL.
2. Keep the packing nut/wet-cup just tight
enough to stop leakage.
See Fig. 5. Overtighten

ing causes binding and excessive packing wear
.
Follow the
Pressure Relief Procedure
, page 1
1.
Then use a round punch or brass rod and light
hammer to adjust the nut.
3. Clean the fluid filter (15) often
, and whenever
the sprayer is stored. Follow the
Pressure Relief
Procedure
, page 1
1, before cleaning the filter
.
4. Lubricate the bearing housing (A)
after every
100 hours of operation
. Follow the
Pressure
Relief Procedure
, page 11. Remove the front
cover
. Fill the bearing housing cavity with SAE 10
non-detergent oil. See Fig. 4.
5. For very short shutoff periods,
leave the suction
tube in the paint, relieve pressure, and clean the
spray tip.
6. Flush the sprayer at the end of each work day
and fill it with mineral spirits to help prevent pump
corrosion and freezing. See page 9.
CAUTION
T
o prevent pump corrosion, and to reduce the
chance of fluid freezing in the pump or pressure
control in cold weather
, never leave water or any
type of paint in the sprayer when it is not in use.
Freezing can seriously damage the sprayer or result
in a loss of pressure or stalling.
7. Coil the hose and hang it on the hose rack
when storing it, even for overnight, to help protect
the hose from kinking, abrasion, coupling damage,
etc.
