CHECKING THE BATTERY AND ACID LEVEL
• Danger of injury! The battery contains highly toxic battery
acid which may squirt out and burn your eyes!
Use goggles and rubber gloves if you work on the battery.
Immediately rinse your eyes or skin using plenty of water
and immediately seek medical attention.
• Gases which may explode can form inside in the battery!
Do not come with open fire or sparks into proximity of the
battery. Do not smoke.
1. For maintenance operations, park and secure the machine
as described in chapter "Preparing the Machine for Mainte-
nance".
2. Check the battery and pole terminals for proper fit.
3. Clean the environment of the plugs.
4. Remove all plugs and check whether the battery acid is at
the acid level markings. Refill distilled water if the acid level
is too low.
☞
• In cold weather, refill distilled water only immediately be-
fore starting the machine. The water can then mix with the
battery acid and does not freeze.
5. Measure the specific density of the battery acid and read off
the battery charging using the following conversion table.
6. Recharge insufficiently charged batteries.
7. Lock the cells with the cleaned plugs.Re-Charging the Bat-
