WARNING

Danger of injury! The battery contains extremely corrosive
battery acid that may spurt out and burn the eyes.

Wear safety goggles and rubber gloves when working on the
battery. Immediately wash battery acid from your skin and
eyes with large amounts of water and consult a doctor.

Gases that form in the battery may explode.

Do not bring open fire or sparks near the battery. Do not
smoke.
1. For maintenance work, park and secure the machine as
described in chapter 5.1 “Maintenance guide” (5-2).
2. Check the battery and terminals for firm seat.
3. Clean the area around the stoppers.
4. Remove all stoppers and check if the battery level is at the
markings. Add distilled water if the battery acid level is too
low.
NOTICE
In cold weather, add distilled water only immediately before
operation. This allows the water to mix with the battery acid and
prevents it from freezing.
5. Measure the specific density of the battery acid, and deter-
mine the battery charge with the conversion table.
6. Recharge insufficiently charged batteries.
7. Plug the cells with clean stoppers.
