Ransburg DR-1 Plastic Fluid Regulator LREG5001 - Manual (Page 15)

TEST PROCEDURES
(Refer to Figure 1)
After repair is complete, test the regulator in the
following manner:
1. Set air and fluid regulators to zero and attach
air and fluid lines to the regulator.
2. Gradually increase air pressure to the regulator
to 80 psi, visually checking for leaks. Tighten
Item 4 (screws) if leakage occurs.
3. Set air regulator to zero. Gradually increase
fluid pressure to 80 psi, visually checking for
leakage. Clean or replace Item 11 (needle and
seat) if leakage at outlet port.
NOTES
4. Gradually increase air pressure on either of the
air lines and visually observe a gradual increase
in fluid flow. If regulator does not perform sat-
isfactorily, inspect components for damage and
replace where required.
PREVENTIVE
MAINTENANCE
1. Rebuild with 73913, repair kit, and 74160-00,
needle and seat, at 6 months minimum, 12 months
maximum.
2. Retorque (8) screws at the following intervals:
- 2 days after rebuild
- Immediately before installation
- 6 month intervals
† If water or solvent is used for testing, it
is normal for minor leakage to occur at the
fluid output port, due to the low viscosities
of these fluids.
