JCB Generator G20QS

WARNING: Do not top the battery up with acid. The electrolyte could boil out and burn you.

Maintenance free batteries used in normal temperate climate applications should not need topping up.

However, in certain conditions (such as prolonged operation at tropical temperatures or if the alternator overcharges) the electrolyte level should be checked.

Open the battery access panel and get access to the battery.

Remove the battery from the machine.

Look at the level in each cell.

Enter the electrolyte level above the plates (in mm)

Check the condition of the coolant hoses

Check the radiator and intercooler surfaces for signs of damage

If service is required, describe the issue

Sign off on the cooling pack check

Notice: Do not exceed the correct level of engine oil in the sump. If there is too much engine oil, the excess must be drained to the correct level. An excess of engine oil could cause the engine speed to increase rapidly without control.

WARNING Hot oil and engine components can burn you. Make sure the engine is cool before doing this job.

Used engine crankcase lubricants contain harmful contaminants. In laboratory tests it was shown that used engine oils can cause skin cancer.

CAUTION It is illegal to pollute drains, sewers or the ground. Clean up all spilt fluids and/or lubricants.

Used fluids and/or lubricants, filters and contaminated materials must be disposed of in accordance with local regulations. Use authorised waste disposal sites.

Remove the engine oil drain plug. Drain the oil in to a suitable container.

Do not attempt to wash or clean the elements, they must only be renewed.

2. Depress the clips on the cover and lift off the cover.

3. Remove the outer element. Take care not to tap or knock the element.

4. If the inner element is to be changed, lift up, pull and remove the inner element.

1. Replacement is a reversal of the removal procedure.

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.
