JCB Generator G45QS

CAUTION: This component is heavy. It must only be removed or handled using a suitable lifting method and device.

Notice: Before you install a pair of batteries to a machine, make sure you know the machines voltage. Some machines require two batteries but have a 12 V electrical system. This means the batteries need to be connected in parallel.

For 24 V machines, the batteries must be connected in series. Incorrect voltage may result in serious damage to the electrical system.

The illustrations show typical battery connections. The actual battery connections installed on your machine may look different.

Get access to the battery or batteries (depending on the specification of your machine).

If installed, move the battery isolator switch to the off position and then remove the key.

Disconnect the negative battery lead first.

Disconnect the positive battery lead and put it away from the batteries.

Get access to the engine compartment

Carefully loosen the radiator cap. Let any pressure escape before removing the cap.

Check that the coolant level is flush with the top of the filler neck.

Fill with 50% antifreeze and 50% decalcified water until it reaches the correct level and replace the cap.

Top liquid up until the pipes inside the radiator are covered approximatively by the amount specified. Do not overfill the radiator, but leave room for the coolant to expand. Length/Dimension/Distance: 5mm

Run the engine to raise the coolant to working temperature and pressure. Stop the engine, checks for leaks and re-check the fluid level.
