Should be like the M600 - 610: Level indicators are a pair of plugs oriented diagonally, you can unscrew, found between the tires on either side a few inches from the bottom of machine. The hydraulic tanks / chain cases, are integrated into the machine. If you are looking at the side of the machine, you're looking at them, large. Should be a vented pipe plug / fill hole on top of each one. Fill it till oil comes out the bottom plug hole on each side. -Scott
