attached charger switches to a hibernation
mode which monitors the batteries and
maintains their charge. The battery charger
powers on intermittently to check voltage and
charge the batteries as necessary.
If a charge is required, the battery charger
sends a minimal level of current. Over time
this low rate of charge helps to extend battery
life by equalizing charge imbalances between
cells. This low charge rate also prevents
damage to the batteries from the forming of
lead sulfate which occurs when batteries
remain in a discharged state.
If there is a power outage while the battery
charger is connected to the batteries the
charger will reset once power is restored. The
charger will automatically check the charge
level of the batteries and reset its hibernation
mode.
WARNING: FROZEN BATTERIES
CAN EXPLODE and result in death
or serious injury. DO NOT charge a
frozen battery. Let the battery thaw
before charging.
Scraper Blade
The scraper blade allows the back of the
housing to keep better contact with the
surface being cleared. It also prevents
damage to the housing from normal use.
IMPORTANT: DO NOT allow scraper blade to
wear too far or auger/impeller housing will
become damaged.
Skid Shoes
The skid shoes control the distance between
the scraper blade and the ground. Adjust skid
shoes equally to keep blade level with the
ground. Refer to Check Function of Clutches
on page 16 for recommended settings.
PRE-START
Charging the Batteries
IMPORTANT: Batteries MUST be connected
to battery charger after every use, regardless
of length of time unit was operated. After
batteries are charged the battery charger
must remain connected until the next use.
Failure to keep batteries fully charged will
reduce battery life and void battery warranty.
WARNING: DO NOT use battery
chargers other than those
recommended by an authorized
Ariens dealers. Incorrect battery
charging will void warranty and can
