Install assembled parts (16) in fillcap opening of hydraulic reservoir.(10) Install flowmeter in loader cab.(11) Set flowmeter controls as follows:RANGE switch in HI positionON/OFF switch in ON positionPRESSURE VALVE control completely openFLOW switch in FLOW position(12) Start and operate engine at idle speed.(13) Press and hold flowmeter TEMPERATURE switch and watch flowmeter TEMPERA-TURE gage. Gage should indicate 130 degrees. If indication is not correctgo to step (14) below; if gage indicates 130 degrees go to step (16)below.(14) Press accelerator pedal and increase engine speed to 1500 rpm and closeflowmeter PRESSURE VALVE control until flowmeter PRESSURE gage indicates1000 psi. Watch flowmeter TEMPERATURE gage while pressing and holdingflowmeter TEMPERATURE switch. Continue to operate engine at 1500 rpm un-til gage indicates 130 degrees then release accelerator pedal.(15) Open flowmeter PRESSURE VALVE control completely.(16) Press accelerator pedal and increase engine speed to 2000 rpm. Recordflowmeter FLOW gage reading.(17) With engine operating at 2000 rpm, slowly close flowmeter PRESSURE VALVEcontrol until PRESSURE gage indicates 2000 psi.(18) Ensure that engine speed is 2000 rpm and record flowmeter FLOW gage read-ing.3-629
