7.8.2 Removing Oil, Refilling Oil
This section describes how to remove oil from the pump and how to refill the oil.
See Overview on page 28 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.
2.
Remove the oil drain plug.
The oil will drain from the pump.
3.
Replace the oil drain plug.
Follow the steps below to add oil to the pump. You can follow these steps after all oil has been
removed, but also to refill oil.
