Maintenance - Section 4 OM4012.2 Page 4-16 Reciprocating Pump Automatic Lube System GENERAL INSTRUCTIONS Lubricant Required for System Refer to “Lubrication Chart”, for correct lubricant speci- fications. 1. Above 90°F (32°C) - Use NLGI No.2 multipurpose grease (MPG). Over pressurizing of the system, modifying parts, using incompatible chemicals and fluids, or using worn or damaged parts, may result in equipment damage and/or serious personal injury. 2. -25° to 90°F (-32° to 32°C) - Use NGLI No. 1 MPG. * DO NOT exceed the stated maximum working pressure of the pump, or of the lowest rated component in the system. 3.
Below -25°F (-32°C) - Refer to local supplier for extreme cold weather lubricant requirements. System Priming * Do not alter or modify any part of this system unless approved by factory authorization. The system must be full of grease and free of air pockets to function properly. After maintenance, if the primary or secondary lubrication lines were replaced, it will be necessary to reprime the system to eject all entrapped air. * Do not attempt to repair or disassemble the equipment while the system is pressurized. * Make sure all fluid connections are securely tightened before using this equipment. NOTE:
To run the grease pump when priming the lube system, connect a jumper wire between the ignition and solenoid posts on the solid state timer . * Always read and follow the fluid manufacturer’s recommendations regarding fluid compatibil- ity, and the use of protective clothing and equipment. 1. Fill lube reservoir with lubricant, if necessary. 2. Remove plugs from all injector manifold dead ends and supply lines. * Check all equipment regularly and repair, or replace, worn or damaged parts immediately. 3. Run grease pump until grease flows from any one plug opening in the system. Replace plug in this opening. This equipment generates very high grease pres- sure.
Extreme caution should be used when oper- ating this equipment as material leaks from loose or ruptured components can inject fluid through the skin and into the body causing serious bodily injury including possible need for amputation. Ade- quate protection is recommended to prevent splashing of material onto the skin or into the eyes. 4. Repeat step 3 until all lines are full and all plugs replaced. NOTE: Fill each feed line with grease before connect- ing lines to the injector outlets and bearings. This will prevent having to cycle the individual injectors once for each 1.0 in. (25 mm) length of feed line between the injector and bearing fitting .
If any fluid appears to penetrate the skin, get emer- gency medical care immediately! Do not treat as a simple cut. Tell attending physician exactly what fluid was injected. System Checkout To check system operation (not including timer), pro- ceed as follows: If overpressurizing of the equipment is believed to have occurred, contact a factory authorized warranty and service center for inspection of the pump. Specialized equipment and knowledge is required for repair of the pump or adjustments other than the maintenance specified in this manual. 1. Lift the passenger seat and connect a jumper wire between “SOL” terminal and “LUBE SW” terminal on the 24 VDC solid state lube timer.
Turn keyswitch "ON". Pump should operate. NOTE: If terminal post identification on the solid state timer is not legible, refer to Figure 4-8 for terminal positions . Annual inspection by the factory authorized warranty and service center is recommended. 2. Keep jumper wire connected until the pump stalls. 3. Disconnect jumper wire. System should vent. Turn keyswitch "OFF".
