Checking the Fluid Level
1. Prepare the Machine
Position the machine on level ground with the bucket
and dipper rams fully extended and the boom lowered to
rest the attachment on the ground, as at A.
2. Check the Level
Look at the fluid level in the sight tube B. The level
should be between the two marks on the tube. If the fluid
is cloudy, water or air has entered the system. Water or
air in the system could damage the hydraulic pump.
