OPERATING INSTRUCTIONS

CHARGING THE UNIT

Make sure the charging station is securely
fastened to a wall and the charger is plugged
into a working wall outlet. See Mounting the
Charging Station.

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. 5). The barrel
connector in the charging station will insert
into the unit. See Replacing the Charger if it
does not. 

2. When the red indicator light on the unit is on,

the battery is being charged (Fig. 6).

If the light fails to come on, check for the
following:

a. Charger is plugged into a working wall

outlet.

b. Unit is firmly seated into the charging

station and the barrel connector is fully
inserted into the unit.

c. Barrel connector properly installed into the

charging station. See 

Replacing the

Charger

if it is not, page 13.

d. Power at the wall outlet.

NOTE:

If the wall outlet is operated by a
switch, be sure the switch is 

ON

.

WARNING:

To prevent serious

personal injury, have the wall outlet
checked by a qualified electrician.

3. The battery should be charged for at least 

24 hours between uses.

NOTE:

The trimmer’s operating time and the
life of the battery will be shorten if
step 3 is not followed.

4. Always place the unit back on the charging

station after each use. The unit is designed
so that that battery cannot be overcharged. 

NOTE:

The battery will heat up while the 
unit is being charged. Be sure the air
vents on the battery housing are kept
cleared for proper ventilation (Fig. 5). 

Charging Tips for Maximum
Performance

Store and charge the unit in an area where
temperatures are between 50˚ F (10˚ C) and
100˚ F (38˚ C).

Storing the unit or batteries in an area 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 be
charged 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.

Unit run time will be reduced when the battery is
not fully charged.
