Maintenance:
The routine maintenance includes only the timely replacement
of the oil! (NOTE: a NEW reduction gearbox is supplied without
oil!)
For correct use of the unit you are recommended to use oil
type: SAE 80W90 - API GL5
To check and add oil, follow these steps:
Respect the environment! Don’t let the oil drop on the floor!
• step 1 : rotate the gearbox until the drive is set as shown with
one of the two front lling plugs (2) set horizontally (figure2). The
other plug (1) is placed nearly vertically.
• step 2 : unscrew both the front plugs (1&2).
• step 3 : use a good quality SAE 80W90 - API GL5 oil and fill
gearbox through the top front plug (1) using a volume of 3.0 -
3.5 qts (2.8 - 3.2 liters) oil.
The oil introduced is still correct when level touches the middle
of the level plug (2).
• step 4 : screw in order the level plug (2) and the filling plug
(1).
After 50 working hours it’s advisable to check the oil level. If the
oil level is lower than expected, please restore it!
Oil should be changed every 500 working hours!
