The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual or on warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable. WARNING 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. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For complete information about your material, request MSDS from distributor or retailer. • Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use. • Check equipment daily. Repair or replace worn or damaged parts immediately with genuine manufacturer’s replacement parts only. • Do not alter or modify equipment. Alterations or modifications may void agency approvals and create safety hazards. • Make sure all equipment is rated and approved for the environment in which you are using it. • Use equipment only for its intended purpose. Call your distributor for information. • Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces. • Do not kink or over bend hoses or use hoses to pull equipment. • Keep children and animals away from work area. • Comply with all applicable safety regulations. SKIN INJECTION HAZARD High-pressure fluid from dispensing device, 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 dispensing device at anyone or at any part of the body. • Do not put your hand over the fluid outlet. • Do not stop or deflect leaks with your hand, body, glove, or rag. • Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or servicing equipment. • Tighten all fluid connections before operating the equipment. • Check hoses and couplings daily. Replace worn or damaged parts immediately. 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 MSDSs 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 chemically impermeable gloves when spraying, dispensing, or cleaning equipment. 2 309032L Operation Operation Pressure Relief Procedure Follow the Pressure Relief Procedure whenever you see this symbol. This equipment stays pressurized until pressure is manually relieved. To help prevent serious injury from pressurized fluid, such as skin injection, splashing fluid and moving parts, follow the Pressure Relief Procedure when you stop spraying and before cleaning, checking, or servicing the equipment. NOTE: If you suspect the dispensing valve, extension, or grease fitting coupler is clogged, or the pressure has not been fully relieved after following the previous steps, using a rag VERY SLOWLY loosen the coupler or hose end coupling and allow pressure to be relieved gradually, then loosen the part completely then clear the clog. Adjustment The dispense valve provides positive control of high pressure lubricants. When supplied with air the pump will start when the valve is triggered and still stall against pressure when the trigger is released. 1. Close the supply pump’s bleed-type master air valve (required in pneumatic systems). 2. Open the dispensing valve until pressure is fully relieved. 1. Relieve the pressure, see Pressure Relief Procedure. 3. Open the fluid drain valve at the pump fluid outlet. Leave the drain valve open until you are ready to use the system again. 2. To adjust the clearance, loosen the top nut (5, Fig 1) and turn the bottom nut (5) in or out as needed. To increase grease flow turn bottom nut in. To reduce grease flow turn bottom nut out. Hold the bottom nut in place and securely tight the top nut. 7 5 Yoke Rod Guide 11 Torque 90 – 110 ft. lbs. FIG. 1 309032L 3 Service Service 9. Push plunger rod (15) through seal (4).
