TOXIC FLUID HAZARD Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or swallowed. • Know the specific hazards of the fluid you are using. • Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local, state and national guidelines.
• Always use Genuine Graco Parts and Accessories, available from your Graco distributor. If you supply your own accessories, be sure they are adequately sized and pressure-rated for your system. •...
Mounting the Pump • For ease of operation and service, mount the pump so the air inlet, fluid inlet, and fluid outlet ports are easily accessible. • Mount the pump in a well-ventilated area with suffi- cient clearance on all sides for operator access and servicing.
Installation Air Line 1. Install the air line accessories as shown in F Be sure the air line supplying the accessories is grounded. a. The fluid pressure can be controlled with either an air regulator (F) to control the air into the pump, or with a fluid regulator (H) to control the fluid out of the pump.

Installation Grounding Before operating the pump, ground the system as explained below. Read the warnings on page 3. Ground all of this equipment: • Pump: use a ground wire and clamp. See F Loosen the grounding screw (X). Insert one end of a 12 ga (1.5 mm ) minimum ground wire (Y) under the clamp and tighten the screw securely.
Operation Pressure Relief Procedure Read the warnings on page 3, and follow the Pres- sure Relief procedure below whenever you: • are instructed to relieve pressure • stop spraying • check or service any of the equipment • install or clean the fluid nozzle. 1.
Maintenance Maintenance Lubrication CAUTION Lubrication of the pump is not required. Oil is exhausted through the muffler, which could contami- nate the fluid supply or other equipment. Excessive lubrication can also cause the pump to malfunction. Flushing and Storage Flush the pump often enough to prevent the fluid you are pumping from curing, drying, or freezing in the pump and damaging it.
Troubleshooting Relieve the pressure (page 10) before checking or servicing the equipment. Problem Pump cycles at stall or fails to hold pressure at stall. Pump will not cycle, or cycles once and stops. Pump operates erratically. Air bubbles in fluid. Pump running irregularly.
A qualified technician should make all repairs. • Inspect and clean all parts thoroughly before reassembly. • Use only genuine Graco replacement parts, available from your Graco distributor. • Be careful not to damage sealing surfaces. • Replace all o-rings removed from the pump.
Replace the Diaphragms Wear gloves when removing or assembling the dia- phragms to reduce the risk of cuts. Diaphragm Repair Kit 246011 is available. Parts included in the kit are marked, for example (9*). For the best results, replace both diaphragms. Always replace the ball check seals (29) when- ever the fluid covers are removed.
