- Using two wedges of different height, rest the
cutterbar higher on opposite side of drain plug.
- Remove the inner skid shoe (1) on drive side.
- Place a container of sufficient capacity under drain
plug.
- Remove filler plug (2) and its washer.
- Remove drain plug (3) and its washer.
- Allow oil to drain completely.
- Wait for dripping to stop.
- Clean and reinstall drain plug (3) and its washer
(replace them if necessary).
- Pour the correct oil quantity and quality through the
opening of the filler plug.
- Clean and reinstall filler plug (2) and its washer.
- Reassemble the unit.
Before draining oil, operate the machine for a few
minutes so that the oil warms up.
The cutterbar is lubricated with 2 L (0.52 US gal) of extreme-pressure gear oil with viscosity grade
SHELL SPIRAX A and SAE 80W90 grade API.
When draining and refilling, it is recommended to use either a mineral base oil with viscosity grade
SAE 80W90 and API grade GL5, or a synthetic base oil, type PAO (Poly-Alpha-Olefins) with a viscosity
grade equivalent to SAE 80W90.
Never use an oil of viscosity SAE 90 in the
cutterbar.
Attach and lock safety chains on the highest
tractor attachment position.
