START-UP PROCEDURE 2.8 The following start-up procedure should always be adhered to when starting up a new installation or when restarting after pump repairs have been made. 1 Fill the hydraulic oil reservoir to the proper level. ( fig. C1878 ) F 2 WARNING This start-up procedure must be made with the loader securely raised off the ground. 2 Check inlet and pressure hose fittings for proper tightness prior to starting. 4 The pump must be filled prior to start-up with fil- tered oil. Fill the pump by pouring oil into the case drain port. (fig. C4257 location “F” ) In the case of this loader, the case drain is filled by gravity from the tank.
The fit- ting should loosen be double checked that there is oil pre- sent. 5 Disconnect the engine stop solenoid wiring, or remove the fuse connected to the red wire. (fig. C1887, C1692) 6 Turn the engine over by engaging the starter. Repeat this step, turning the engine over in 15 second interval, 5 or 6 times. This will fill the rest of the hydraulic hoses. 7 Reconnect the engine stop solenoid or replace the fuse. C4257 Internal charge pump model shown WARNING Use caution when dealing with hydraulic fluid under pressure. Escaping fluid under pressure can pene- trate the skin and cause serious injury. 8 Start the engine and let idle at lowest possible set- ting.
9 Check for leaks and make adjustments as required. Do not use your hands to check for leaks while the engine is operating. 10 Replenish the hydraulic oil reservoir as required. (fig C1690 fig C1878) 11 Start the engine and increase the rpm to half throttle. Bring the hydraulic fluid up to operating temperature and make control adjustments as outline in Section 4.
