CHARGING THE UNIT
Make sure the charging station is securely fastened to a
wall and the charger is plugged into a working wall
outlet.
NOTE: Allow the unit to charge for at least 36 hours
prior to first use.
1. Slide the unit down into the charging station until it is
firmly seated (Fig. 4). The barrel connector in the
charging station will insert into the unit. If it doesn’t,
refer to Replacing the Charger.
NOTE: The battery will heat up while the unit charges.
Be sure the air vents on the battery housing are
kept clear for proper ventilation (Fig. 4).
Charging Tips for Maximum Performance
• Store and charge the unit where temperatures are
between 50˚ F (10˚ C) and 100˚ F (38˚ C). Storing the
unit or batteries above 100˚ F (38˚ C) will reduce
battery life.
• Storage below 50˚ F (10˚ C) will not reduce battery
life, but may require a longer charging time.
• Store the unit on the charging station when not in
use. The unit is designed so that the battery cannot
be overcharged.
NOTE: The charging indicator light will remain lit when
the unit is properly installed in the charging
station.
Temperature Effects on Charging Time
• 50˚ F (10˚ C) to 100˚ F (38˚ C) – Battery will charge
within 24 hours.
• 40˚ F (4 ˚C) to 50˚ F (10˚ C) – Battery will require up to
48 hours for a full charge.
• Below 40˚ F (4 ˚C) – Battery will not reach full charge.
NOTE: The unit run time will be reduced when the
battery is not fully charged.

3. Charge the battery until the Charging Indicator Light
on the charger turns from red to green (Fig. 5).
NOTE: The unit’s operating time and the life of the
battery will be shorten if the unit is not fully
charged between uses.
4. Place the unit back on the charging station after
each use. The unit is designed so that the battery
cannot be overcharged.
If the wall outlet is
not working properly,
have the wall outlet checked by a qualified
electrician. This will help prevent serious
personal injury.
