Page 6: Maintenance And Lubrication
MAINTENANCE AND LUBRICATION Engines are shipped without oil or gasoline. Refer to MANUFACTURER'S INSTRUCTIONS for proper procedures and recommended fluids. SHUT OFF ENGINE to adjust, service, clean or refuel the machine. HYDRAULIC RESERVOIR: The hydraulic reservoir should be filled to the "FULL" mark on the dipstick with recommended hydraulic oil. -
Page 7: Operating Instructions
BEFORE STARTING THE ENGINE, Be sure that: 1) Engine is properly prepared to Manufacturer's specifications. Refer to engine manufacturer's instructions. 2) Fuel valve is open. 3) Hydraulic fluid level is maintained properly. 4) Hydraulic flow valve lever is in "START/OFF" position. 5) Battery is properly charged. - Page 8 operating instructions, continued... HYDRAULIC FLOW BYPASS VALVE: The PS-18/19/20/24 hydraulic power source is equipped with a hydraulic flow bypass valve which diverts the hydraulic flow to the reservoir ("START/OFF" position), or to the pressure coupling ("ON" position). The hydraulic flow bypass valve allows tools to be coupled and uncoupled to the power source without shutting off the engine.
- Page 9 CONNECTING TOOLS: Before connecting any tool to the hydraulic power source, make sure that it is compatible with the flow and pressure range of the power source. Also make certain that the relief valve setting, which determines the maximum pressure that the unit will apply to the tool, is properly adjusted. IMPORTANT: CHECK the flow direction of the tool.
