3.3.4 To Oil Bleed the Pump
As delivered from the factory, the pump would have already been oil bled (except pump
heads supplied separately). If necessary, oil bleed the pump as follows:
Note: Refer to the lubrication chart given in Section 4, Table 4.2 for details of pump oil types
and capacities.
i. Fill the pump to the top of the crankcase with the correct oil (or ensure oil is in the
expansion bottle, if fitted).
ii. Set the selector valve to the recycle (dump) position and start the engine/motor. Run
at 750 rpm tick-over to prime, or inch electric motor (on/off).
Note: If the unit is fitted with a shut-down protection device, hold in the override button
for 10 seconds (this allows the engine oil pressure to build up).
iii. With reference to Fig 3.1, put a finger on top of an oil bleed screw on a lower barrel
and open the screw slowly using a suitable spanner. When air-free oil flows, tighten
the bleed screw firmly.
Note: Top up oil in the pump crankcase after each barrel has been bled.
iv. Repeat the procedure detailed in iii. for each barrel, starting from the lower barrels
first.
v. When the operator has taken up a working position, move the selector lever to the
High Pressure position and increase engine speed to reach working pressure.
vi. If the delivery line vibrates or the pump does not run smoothly, stop the unit and carry
out a water bleed (3.3.5) and then repeat the oil bleed.
