Bearing Maintenance

a) Remove vent plug. Tilt the reservoir down. Pour oil through the hole left by the vent plug until oil appears in the vertical
section of the elbow connecting bearing bracket and reservoir.
b) Fill up the reservoir
c) Snap the reservoir back into position. After 10 minutes, check wether the oil level in the reservoir has dropped into the
support, completing this way the necessary level, which is the centerline of the inferior ball bearing indicated in the Fig.
18.
During the pump operation, if oil level reduce to approximately 1/3 of the reservoir capacity, it must be filled up according to
the instructions mentioned in this item.
Attention: A defective lubrication or an excessive one may cause damage.

Lubrication intervals and oil specifications

The first oil change should be made after the first 200 or 300 working hours. The next oil change should be made after 1500
or 2000 service hours. This will avoid dirt particles, which have not been eliminated by cleaning, to contaminate oil and
damage bearings.
Then, oil change should be made every 8000 effective working hours or at least once a year (the one becomes first).
Bearings should be washed every 2 years (as a minimum).
