STORAGE AND FREEZE PROTECTION
Before storing the machine for an extended
period, the machine must be prepped to lessen
the chances of being damaged. It is
recommended that a machine be fully serviced
before being stored. Contact an authorized
TENNANT service representative.
When storing the machine for an extended period,
never leave the battery packs uncharged (below
15%) for more than three weeks. Allowing the
battery packs to go below 15% while the machine
is being stored could permanently damage the
battery packs.
ATTENTION:Battery packs damaged as a
result of being discharged below 15% will not
be covered under warranty.
