Slew Ring Bearings
Lubricate
WARNING You will be working close into the machine for these jobs. Lower the attachments. Remove
ignition key and turn the battery isolator to the off position. This will prevent the motor being started.
Make sure that the slew ring is kept full of grease.
With the cab in the straight ahead position as shown, the grease point is located near the front of the slew
ring. Refer to Figure 101.
Notice: Do not overgrease the slew ring as this will result in the displacement of the grease seal.
