Be careful not to spill oil on the floor.
(The RG131 does not come with an oil pot. It should be prepared by the customer.)

(Be sure to secure the plug in place. This prevents oil from spilling over even if the drain cock is opened
inadvertently.)
10. Press the hose against the hose clip to reattach.
11. Restart oiling.
Add oil from the oil port until oil level is above the center of the oil gauge while observing the oil gauge.
