Checking the Fluid Level
! WARNING
Fine jets of hydraulic fluid at high pressure can penetrate
the skin. Do not use your fingers to check for hydraulic
fluid leaks. Do not put your face close to suspected
leaks. Hold a piece of cardboard close to suspected
leaks and then inspect the cardboard for signs of
hydraulic fluid. If hydraulic fluid penetrates your skin, get
medical help immediately.

should be at the red mark (or above).
! CAUTION
If the fluid in the tube appears cloudy, then water or air
has entered the system. The hydraulic pump could be
severely damaged if the machine is operated. Contact
your JCB distributor immediately.
