Draining the cutterbars
From the working position:
- Using two wedges of different height, rest the
cutterbar unit higher on opposite side of drain plug.
- Place a container of sufficient capacity under the
lower cutterbar end.
- Remove 3 bolts (1).
- Remove outer bracket (2) and its seal.
- Allow oil to drain completely.
- Wait for dripping to stop.
- Clean and reassemble the unit:
• Torque: 9.5 daN m (70 lbf ft). If necessary replace
seal.
- Remove plugs (3) and their seals.
- Pour the correct oil quantity and quality through the
opening of the filler plug.
- Clean and reinstall filler plugs (3) and their
seals. Replace if necessary.
- Invert wedges.
- Follow same procedure on the second cutterbar.
Before draining oil, operate the machine for a
few minutes so that the oil warms up.
The cutterbar is lubricated with 1.4 L (0.37 US gal) of SHELL SPIRAX A extreme-pressure gear oil with
viscosity grade SAE 80W90 and API grade GL5.
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.
