Figure 5.3: Checking the oil level
To check the oil level, park the machine on level ground. Rotate the travel motors until the oil
level checkpoint is approximately horizontal to an imaginary line as per figure 5.3.
IMPORTANT: The oil level checkpoint must be higher than the horizontal oil level before
removing the plug. To refill the gearbox oil, park the machine on level ground. Open
the inlet and outlet plugs. Refill the oil until it reaches the horizontal oil level and a little
comes out of the outlet plug. Then close the plugs again and tighten them properly.
5.4.2 TIGHTENING OF THE SLEWING FRAME MOUNTING BOLT
Perform a proper check of all the front and rear slewing frame mounting bolts. After a few hours
of operation, there is the possibility that the bolts may loosen. As shown in Figure 5.4, the
slewing frame mounting bolts must be retightened back if they have loosened, using the correct
size spanner to prevent the bolt from breaking.
