Maintenance
To reduce the risk of serious bodily injury, including
fluid injection or splashing in the eyes or on the skin,
always follow the Pressure Relief Procedure before
adjusting, cleaning, repairing, or removing the BPR
from the system.
Never completely remove the adjusting screw when
system pressure is present.
Flush the Equipment
Flush the BPR whenever the rest of the system is
flushed. Before flushing, fully open the BPR by reducing
pilot air pressure to zero or turning the adjusting screw
counterclockwise to reduce pressure to zero.
NOTE: Do not allow paint or solvent to remain in the
system for a long time. Fluid could dry on the piston,
causing leakage at the piston packing. If leakage
occurs, disassemble and clean the BPR.

Cleaning
Regular cleaning and inspection, and lubrication of the
BPR are necessary to keep the BPR working properly.
1. Follow the Pressure Relief Procedure on page 7.
2. Remove the BPR from the system.
3. Disassemble the BPR, referring to the parts
drawings on pages 9 and 11. Clean and inspect all
parts.
NOTICE
Use special care when handling the hard carbide por-
tions of the piston (3) and seat (4). Damage causes
poor operation and leakage.
