7.7.2 Removing Oil, Replacing Oil Filter, Refilling Oil
This section describes how to remove oil from the pump, replace the oil filter and refill the oil.
See Overview pump 63 - 300 m3/h on page 59 for the pump fitted in the machine and an
overview of the parts.
If the machine remains unused for a prolonged period of time, the oil must be removed from the
pump. This is necessary because moisture and dirt in the oil may affect the pump, causing the
pump to jam at the next use.
The oil in the vacuum pump may be hot. Avoid contact with hot oil when removing the oil.
Follow the steps below to remove the oil from the pump:
1.
Place a drip pan under the oil drain plug.
