WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 10.
Shutdown and Care
1. Check the packing nut/wet-cup daily (102).
Relieve pressure first. Keep the wet-cup 1/3 full of
TSL at all times to help prevent fluid buildup on the
piston rod and premature wear of packings.
2. Tighten the packing nut/wet-cup (102) just
enough to stop leakage. Over-tightening causes
binding and excessive packing wear. Use a round
punch or brass rod and a light hammer to adjust
the nut. See Fig. 9.
3. Clean the gun's fluid filter often and whenever
the gun is stored. Relieve pressure first. Refer to
manual 308–645.
4. Periodically clean paint residue from the pres-
sure transducer (29) vent hole area. See Fig. 10.
Replace the transducer when leakage is exces-
sive. See page 28.
5. Lubricate the bearing housing after every 100
hours of operation. Remove the front cover. Fill the
bearing housing cavity (A) with SAE 10 non-
detergent oil. See Fig. 10.
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 13.
CAUTION
To prevent pump corrosion, and to reduce the chance
of fluid freezing in the pump 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. For very short shutoff periods, leave the suction
tube in the paint, relieve pressure, and clean the
spray tip.
Shutdown and Care
8. Coil the hose and hang it on a hose rack when
storing it, even for overnight, to help protect the
hose from kinking, abrasion, coupling damage, etc.
