5.7 Electrical system
Specific safety instructions
• The battery contains sulphuric acid! This acid must not be allowed to come into contact
with the skin, the eyes, clothing or the machine
Therefore when recharging or working near the battery:
☞ Always wear goggles and protective clothing with long sleeves
If acid is spilt:
☞ Thoroughly rinse all affected surfaces immediately with plenty of water
☞ Thoroughly wash any part of the body touched by the acid immediately with plenty of
water and seek medical attention at once!
• Especially when charging batteries, as well as during normal operation of batteries, an
oxyhydrogen mixture is formed in the battery cells – danger of explosion!
• In case of a frozen battery or of an insufficient electrolyte level, do not try start-up with a
starting aid. The battery can burst or explode!
☞ Replace the battery immediately
• There must be no naked flame near open battery cells. Avoid sparks. No smoking. The
gas that forms during normal battery operation can ignite!
• Use only 12 V power sources. Higher voltages will damage the electric components
• When connecting the battery leads, ensure that the poles +/– are not inverted,
otherwise sensitive electric components will be damaged
• Do not interrupt voltage-carrying circuits at the battery terminals because of the danger
of sparking!
• Never place tools or other conductive articles on the battery – danger of short circuit!
• Disconnect the negative (-) battery terminal from the battery before starting repair work
on the electrical system
• First remove the (–) terminal and then the (+) terminal as you disconnect the electrical
system
• Dispose of used batteries properly
Service and maintenance work at regular intervals
Every week
☞ Check once a week:
• Electric fuses
• Cable and earth connections
• Battery charge condition – see Battery on page 5-21
