Shutdown and Care

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.

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.10.

3.

Periodically clean paint residue from the pres-

 

sure transducer (29) vent hole area. See Fig. 11.

 

Replace the transducer when leakage is exces-

 

sive. See page 27.

4.

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. 11.

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 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 damage the sprayer or result in a loss of pressure or stalling.

6.For very short shutoff periods, leave the suction tube in the paint, relieve pressure, and clean the spray tip.

7.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.
