4.1.7 Cooling circuit

The engine fan draws in cool air via the openings made in the sides of the generating set and on the battery side. The alternator fan
draws in cool air via the openings made in the side walls of the casing. The cool air is mixed with the exhaust gases and is then
expelled from the exhaust outlet. To avoid any risk of damage to the generating set as a result of overheating, always keep the inlet
and outlet openings of the casing clean and free from any obstruction.
Note: do not block the generating set's cool air inlets and do not fit additional equipment on top: this would lead to overheating and
could seriously damage the generating set.

4.1.8 Exhaust circuit

Remove all flammable matter from the area surrounding the exhaust. This flammable matter includes building materials as well as
the natural environment.
Maintain a minimum distance of 1.5 m between the exhaust outlets and dry grass, leaves and other flammable
landscaping materials.
Periodically check that there are no cracks, leaks or corrosion on the exhaust line components.
Look for any corroded or broken metal parts and replace these where necessary.
Check that the exhaust outlet is free from any obstruction.

4.1.9 Battery

Battery short circuits. Danger of death or serious injury as a result of explosion.
A short circuit may cause physical injuries and/or damage to equipment. Disconnect the battery before installing or carrying out any
maintenance operations on the generating set. Do not wear jewellery while carrying out maintenance operations on the equipment.
Use tools with insulated handles. To disconnect the battery, disconnect the negative lead (-) first. To reconnect the battery,
reconnect the negative lead (-) last. Never connect the negative lead (-) of the battery to the positive terminal (+) of the starter
solenoid. Never short circuit the terminals to test the condition of the battery.
Clean the battery and its leads and tighten the terminals according to the instructions in the maintenance schedule. To prevent
corrosion, take the necessary measures to ensure that the battery terminal electrical connections are tightened and dry. To deal
with any corrosion which appears on the battery terminals, disconnect the battery leads and rub the terminals with a wire brush.
Clean the battery and its leads with a solution of water and bicarbonate of soda. After cleaning, rinse the battery and leads in clean
water and dry them with a dry lint-free cloth.
Cleaning away battery acid. Battery acid can result in death or serious injury.
Battery electrolyte is an electrical conductor and is corrosive. Add 500 g of bicarbonate of soda to 4 l of water in a container and mix
the neutralisation solution. Pour the neutralisation solution over the splashes of acid and repeat the operation until it is clear that the
chemical reaction (foaming) is complete. Rinse the liquid produced in the reaction with water then dry the treated area.
Reconnect the battery leads, then coat the terminals with vaseline, silicone grease or any other non-conductive grease.
