machine is only partially charged. The battery pack must
be fully charged before using the shovel for the first time.
• Battery Aging – Lithium‑ion batteries are subject to a
natural aging process. A battery pack must be replaced at
the latest when its capacity falls to just 80% of its capacity
when new. Weakened cells in an aged battery pack are no
longer capable of meeting the high power requirements
needed for the proper operation of your machine, and
therefore pose a safety risk.
• Do not exhaustively discharge battery packs –
A complete discharge will damage the battery cells. The
most common cause of exhaustive discharge is lengthy
storage. Stop working as soon as the performance of a
battery falls noticeably or the electronic protection system
triggers. For optimum battery performance, charge the
battery packs frequently. Place the battery packs in
storage only after they have been fully charged.
• Do not overload battery packs – Protect the shovel and
battery from overloading. Overloads will quickly result in
overheating and cell damage inside the battery housing
even if it is not apparent externally. For safety reasons, the
integrated protective cutoff will activate to switch off the
equipment. After regular use, allow the battery packs to
cool to room temperature before recharging them.
IMPORTANT! Do not attempt to turn on the machine if the
protective cutoff has been activated. This may damage
the battery packs.
• Outlet voltage – Please check the data marked on the
rating label of the battery charger. Be sure that the voltage
of the power supply matches that marked on the rating
label. Never connect it to a different mains voltage.
• Charger use – Do not use the supplied battery charger to
charge other types of battery packs or tools.
• Do not overcharge battery packs – Do not exceed the
maximum charging times. Frequently overcharging the
battery packs will result in cell damage. Do not leave
battery connected to the charger for days on end.
• Battery pack abnormalities – Do not use batteries that
have suffered swelling or deformation or those that exhibit
other atypical symptoms (gassing, hissing, cracking, etc.).
• Electrostatic discharge – When handling batteries, be
wary of electrostatic charge. Electrostatic discharges can
damage the electronic protection system and the battery
cells. To avoid electrostatic discharges, never touch the
battery terminals.
