Warning Symbol
WARNING
This symbol alerts you to the possibility of serious
injury or death if you do not follow the instructions.
Caution Symbol
CAUTION
This symbol alerts you to the possibility of damage to
or destruction of equipment if you do not follow the
corresponding instructions.
NOTE: The following warning applies only to Models 214018, 208250, 214019, & 210097, which contain aluminum
housings.
WARNING
Hazard of Using Fluids Containing Halogenated Hydrocarbons
Never use 1,1,1–trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or fluids containing such solvents in the models listed in the not above. Such use could result in a serious chemical reaction,
with the possibility of explosion, which could cause death, serious injury and/or substantial property damage.
Consult you fluid suppliers to ensure that the fluids being used are compatible with aluminum parts.
Installation
Connect the Fluid Hose
Regulators or Circulating Adapters:
Connect the fluid hoses to the 1/4 npsm(m) inlet and
return fittings.
Straight Adapter:
Connect a hose to the 3/8 npsm(m) inlet fitting.
Connect the Regulator or Adapter to the Gun
Model 223622:
Screw the regulator union adapter onto the gun fluid
inlet.
Models with Twist-lock Couplers:
Screw the coupler stem onto the gun inlet. Connect the
twist-lock couplers by lining up the coupler slots with
the pins on the stem, pushing the coupler onto the
stem, then twisting the coupler clockwise to lock it.
Models with Slip-ring Couplers:
Pull the slip ring back as you push the coupler onto the
stem.

Operation
CAUTION
To avoid damaging the regulator diaphragm, never
exceed 200 psi (1.4 MPa, 14 bar) Maximum Inbound
Fluid Pressure to the regulator.
Service
WARNING
To reduce the risk of serious injury, including
splashing in the eyes or on the skin, always shut off
the air and fluid pressure to the gun and trigger the
gun to relieve fluid pressure in the hoses before
disconnecting hoses from the regulator or adapter.
To Clean or Service the Regulator
1. Relieve the air and fluid pressures.
2. Disconnect the regulator from the gun and the
hoses from the regulator.
To Adjust the Fluid Pressure
Trigger the gun. Turn the fluid regulator setscrew (2)
clockwise to the desired setting. Release the gun
trigger, tighten the locknut (1), and install the acorn nut
(16).
4. Clean and inspect the parts carefully.
5. Replace worn or damaged parts and reassemble
the regulator. Be sure the nylon side of the diaphragm (12) faces the fluid.
Torque Notes:
Diaphragm Nut (3) onto Valve Stem (8):
6 to 10 in-lb (0.7 to 1.1 NSm)
Screws (5) into the Housing (18):
20 to 30 in-lb (2.3 to 3.4 NSm)
3. Disassemble the regulator. Refer to the Parts
Drawing.
Cap (14 )into the Housing (18):
10 to 15 ft-lb (13.5 to 20.0 NSm)
