High-pressure fluid from gun, hose leaks, or ruptured components will pierce skin. This may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical treatment.
??? Do not point gun at anyone or at any part of the body.
???Do not put your hand over the dispense outlet.
???Do not stop or deflect leaks with your hand, body, glove, or rag.
???Follow Pressure Relief Procedure in this manual, when you stop dispensing and before cleaning, checking, or servicing equipment.
TOXIC FLUID OR FUMES HAZARD
Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.
???Read MSDS???s to know the specific hazards of the fluids you are using.
???Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.
???Always wear impervious gloves when spraying or cleaning equipment.
???If this equipment is used with isocyanate material, see additional information on isocyanates in Iso- cyanate Conditions Section of this manual.

???Do not expose to rain. Store indoors.
EQUIPMENT MISUSE HAZARD
Misuse can cause death or serious injury.
???Do not operate the unit when fatigued or under the influence of drugs or alcohol.
???Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals.
???Do not leave the work area while equipment is energized or under pressure. Turn off all equipment and follow the Pressure Relief Procedure in this manual when equipment is not in use.
???Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manu- facturer???s replacement parts only.
???Do not alter or modify equipment.
???Use equipment only for its intended purpose. Call your distributor for information.

2.Pressurize the feed systems connected to the metering valve to prime the system. See Technical Data on page 23 for maximum inlet feed pressure.
3.Dispense several full stroke shots until material is air-free and has good shut-off at the nose.
NOTE: Very viscous, compressible materials may con- tinue to droll after system is primed. Reduce flow rate as required to produce air-free dispense.
NOTE: Very thin materials may require tilting the valve greater than 45 degrees and dispensing shots until material is air-free. Remove oil from cups before pro- ceeding.
Adjusting the Shot Size
Adjusting the Shot Size
1.Rotate the shot size locking ring counterclockwise to loosen.
2. Rotate the shot size adjuster to adjust shot size.
3.Rotate the shot size locking ring clockwise to tighten.
4.Dispense into waste container to test shot size.
5.Repeat until desired shot size is achieved.

Sequence of Operation
Step 1: Reload
??? The balanced spool shifts to the dispense position
??? Material path to the needle is opened
??? Material feed inlet port is blocked
??? Metering rod remains in the retracted position
Step 3: Dispense
???Spool shifts to the right
???Material feed inlet is opened
???Material is transferred into the metering chambers by a pressurized feed system
???Outlet port is blocked
???Metering rod is retracted to a precise position deter- mining the volume of each material
??? Metering rod extends
??? Material is dispensed from the metering chamber into the needle
Upon completion of the dispense stroke, the metering rod and spool shifts back to the reload position.
