EVERY 250 HOURS MAINTENANCE

CHECK OIL LEVEL IN SWING MACHINERY 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.
1. Remove dipstick (G) and wipe the oil from the dipstick with
a cloth.
2. Insert dipstick (G) fully in the guide.
3. When dipstick (G) is pulled out, if the oil level is between the
H and L marks of the gauge, oil level is proper.
4. If the oil does not reach the L mark on dipstick (G), remove
oil filler (F), and add engine oil.
5. If the oil level exceeds the H mark on the dipstick, loosen
drain valve (P) to drain the excess oil.
6. After checking oil level or adding oil, insert the dipstick (G)
into the hole and install oil filler (F) cap.

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 seri-
ous 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.
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 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 engine oil through plug hole (F)
until the oil overflows from plug hole (F).
5. After checking, install plug (F).
The tightening torque for plugs (P) and (F) is 68.6 ± 9 N·m
{50.6 ± 6.6 lbf·ft}.
REMARK
There are two plugs (F). Add oil through the one easier to
fill oil and through which no internal gears are to be seen.
