Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. 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.
Warnings 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.
Installation Installation Grounding The equipment must be grounded to reduce the risk of static sparking and electric shock. Electric or static sparking can cause fumes to ignite or explode. Improper grounding can cause electric shock. Grounding provides an escape wire for the electric current. Z V W Pump: use ground wire and clamp (supplied). Loosen grounding lug locknut (W) and washer (V). Insert one end of a 12 ga (1.

Installation Installation Notes Hydraulic Components NOTICE The hydraulic supply system must be kept clean at all times to reduce the risk of damaging the reciprocator hydraulic power supply. • • Always turn off the supply side valve (G) to avoid possible serious injury or component damage. See the Typical Installation on page 5. Blow out all hydraulic lines with air, flush thoroughly with solvent, and then blow out the air again before connecting the lines to the reciprocator.
Operation Operation Pressure Relief Procedure Hydraulic Fluid Level Check 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.
Repair Shutdown Always shut off the supply line shutoff valve (E) first, and then the return line shutoff valve (G). This is to prevent over pressurizing the reciprocator or its seals. When starting the hydraulic system, open the return line shutoff valve (G) first. See page 5. Repair Flow Control Repair 1. Relieve pressure, see page 7. There are two basic repairs to the hydraulic fluid control; pressure control repair and flow control repair. Pressure Control Repair 1. Relieve pressure, see page 7. 2.
Troubleshooting Troubleshooting Problem Cause Solution No pressure on gauge, or low pressure on gauge Hydraulic power supply malfunction or mis-adjustment Adjust the hydraulic power supply. If the problem remains, refer to the hydraulic power supply instruction manual. Pressure reducing valve is backed out Adjust the pressure reducing valve. Can’t adjust pressure with the pressure reducing valve Clogged valve Clean the pressure reducing valve.
