START-UP PROCEDURE 2.7
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. C3431)
2 The inlet hose from the oil reservoir to the charge
should be filled with oil prior to starting.
3 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 side case
drain port. (fig. C4197 location “D” )
5 Disconnect the engine stop solenoid wiring, or
remove the fuse connected to the red wire. (fig. C3872)
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.
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.
11 Start the engine and increase the RPM’s to half throt-
tle. Bring the hydraulic fluid up to operating temperature
and make control adjustments as outline in Section 4.
