MAINTENANCE PROCEDURE

CHECK OIL LEVEL IN FINAL DRIVE CASE, ADD OIL

The parts and oil are at high temperature immediately after the engine is stopped, and may cause serious burns. Wait for the
temperature to go down before starting the operation.
If there is still pressure remaining inside the case, the oil or plug may fly out. Loosen the plug slowly to release the pressure.
Please do not stand in front of the plug when you loosen the plug.
Prepare a handle.
1. Set the TOP mark at the top, with the UP mark and plug (P)
perpendicular to the ground surface.
2. Remove plug (F) using the handle. When the oil level reaches
a point 10 mm (0.4 in) below the bottom of the plug hole, the
correct amount of oil has been added.
3. If the oil level is too low, install plug (F), operate the travel
levers, and drive forward or in reverse to rotate the sprocket
one turn. Then repeat Step 2 to check again.
4. If the oil level is low, add oil through the hole of plug (F). Add
oil until oil overflows from the hole of plug (F).
5. After checking, install plug (F).
