1. SAFETY STANDARDS
1.1.
DESCRIPTION OF SYMBOLS
Accumulators are heavy! Use suitable transport and
lifting equipment to work safely.
Connecting accumulators in series creates hazar-
dous voltages.
The electrolyte corrodes metals and burns the skin
and all parts of the human body.
WARNING!
Risk of explosion! Avoid short circuits!
Never place tools or metal objects on the accumula-
tors.
Batteries and related parts contain lead.
Lead is dangerous to health if ingested.
