▪
Reconnect the pump to the electrical supply and operate the pump for about
5 to 10 minutes.
▪ Disconnect the pump from the electrical supply, remove the oil drain-plug and
allow the oil to drain out of the pump.
▪
Repeat this step unl the oil reservoir is clean.
6. Ret the oil drain-plug, remove the block and reconnect the pump to the vacuum
system.
7. Fill a suitable container with clean oil and pour the oil into the ller hole unl the
oil-level reaches the MAX level mark on the bezel of the oil sight-glass.
8.
Allow a few minutes for the oil to drain into the pump. If necessary, add more oil.
Ret the oil ller-plug.
6.5 Inspect and clean the inlet-lter
