WARNING

INJECTION HAZARD

To reduce the risk of serious injury,

whenever you are instructed to relieve

pressure, follow the Pressure Relief

Procedure on page 9.

1. Check the packing nut/wet–cup (102) daily. Re-

lieve 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. 11.

3. Clean the gun's fluid filter (if present) often and

whenever the gun is stored. Relieve pressure first.

4. Periodically clean paint residue from the pressure

transducer vent hole (A) area. See Fig. 12. Re-

place the transducer when leakage is excessive.

See page 31.

5. Lubricate the bearing housing after every 100

hours of operation. Remove the front cover. Fill the

bearing housing cavity (B) with several drops of

SAE 10 non–detergent oil. See Fig. 12.

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 12.

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 dam-

age the sprayer or result in a loss of pressure or

stalling.

7. For very short shutoff periods, leave the suction

hose in the paint, relieve pressure, and clean the

spray tip.
