Changing the gearcase oil
- see fig 6
1. Remove the magnetic drain plugs and sealing washers (can also remove the fill/
level plugs for faster drainage).
2. Allow the oil to drain into a can for environmental disposal.
3. Change the oil filter.
4. Clean and then refit drain plugs and re-fill the gearcase with approximately 2.5
litres of oil.
5. Ensuring that the TR20 is level, check oil level by removing a fill plug. There should
be a slight leakage of oil with the plug removed.
The relief valve should be
operated every 3 months to clear
the valve seat and check that the
valve is functional.
(Ear protection is
recommended)
NOTE
If the TR20 unit cannot be
completely drained of oil without
tilting the unit, it will be sufficient
to drain as much as possible.
NOTE
500 hours is the maximum oil
change interval.
NOTE
Drive systems must be maintained in accordance with the manufacturers
instructions.
