WARNING

To reduce the risk of serious bodily injury, always

follow the Pressure Relief Procedure Warning on

page 3 when instructed in this procedure to

relieve pressure.

1. Check the packing nut/wet-cup daily. 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 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. 8.

3. Clean the gun's fluid filter often and whenever

the gun is stored. Relieve pressure first. Refer to

manual 307–614.

4. Lubricate the bearing housing after every 100

hours of operation. Remove the front cover. Apply

several drops of SAE 10 non-detergent oil in the

bearing housing cavity (B). See Fig. 9.

5. 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 15.

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 seri-

ously damage the sprayer or result in a loss of

pressure or stalling.

6. For very short shutoff periods, leave the suction

hose in the paint, relieve pressure, and clean the

spray tip.
