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.

Checking the Fluid Level - for interval see Service Schedule
1 Position the backhoe in the travel position and stop the
engine.
2 Look at the fluid level in the sight glass A. The level
should be visible in the sight glass.
3 If the level needs topping up, wait five minutes, remove
the battery compartment cover, loosen the hydraulic
top-up filler cap B and allow all pressure to dissipate.
4 Open filler cap B and top up with the recommended
fluid. Pour slowly to prevent blow-back.
! !
CAUTION
If the fluid is cloudy, water or air has entered the system.
This could damage the hydraulic pump. Contact your
JCB distributor.

Changing the Filter - for interval see Service Schedule
1 Stop the engine and wait for 5 minutes.
2 Loosen the hydraulic tank filler cap B and allow all
pressure to dissipate. Remove the filler cap.
3 Unscrew the old filter canister C, using a chain wrench
if necessary, and discard.

filter canisters, although visually similar, are different and
must not be mixed.
