GUIDELINES FOR BATTERY PACK AND CHARGER USE
1. Your clipper, battery pack, and charger function as several interacting electrical systems. Good
electrical contact must be maintained in order for the motor to deliver full power, the battery to
charge properly, and the Refresh feature to operate. Limited or erratic performance caused by
dirt or age can be restored in the majority of the cases if you do the following:
A. Problem: Clipper motor starts and stops as if there was a loose electrical connection.
Solution: Remove the battery pack from the clipper. Examine the battery pack opening in the
clipper. Locate the two sets of motor contacts. Gently squeeze the metal leaves until they are
about 1/16 apart using a long pliers or similar. DO NOT squeeze the metal leaves completely
together or the battery pack will not re-insert.
B. Problem: Charger does not fully charge the battery. Solution: Clean the battery pack bottom
contacts (the portion inserted into the charging pocket). Clean the charger contacts. Re-align
the charger contacts. To clean the battery pack contacts, rub gently with a pencil eraser until
they are brightly polished. Use a cotton swab and 91% isopropyl alcohol to remove any residue
or dirt. Denatured alcohol can also be used. Use care, as both products are flammable. Clean
the charger contacts in the same way UNPLUG CHARGER FIRST. Make sure eraser dust and
cleaners do not get inside the charger base. To re-align the charger contacts, again make sure it
is unplugged, and gently pull the metal loops on the four contacts forward SLIGHTLY. Do not
severely bend, deform, or damage the contacts.
C. Problem: Charger does not exit the Refresh mode. Solution: Clean the battery
pack bottom contacts as noted above. Clean and re-align the charger contacts
as noted above.
D. Problem: Charger lights flash on and off as clipper or battery is moved side to
side in the charger pocket. Solution: Re-align the charger contacts as noted above.
2. The charger base is designed to recharge battery packs that are at, or close to, room
temperature (25°C/77°F). If a battery pack is returned to the charger unusually hot or cold, the
charger will not enter fast charge mode. This is normal and the battery pack can remain in the
charger. Under certain conditions the charger may not fully charge a battery pack that has
cooled from an unusually hot temperature. Remove the battery pack for a few seconds, and
return to the charger. The charger will then enter a second fast charge mode.
3. Optimum charging results will be obtained if the charging unit is operated in a place where the
temperature is stable. Sudden increases in temperature may result in the battery pack receiving
less than a full charge. Avoid locating the charger near heat vents, radiators, or in direct sunlight.
4. To increase the life of your battery pack, do not run the clipper until the motor completely stops.
When the motor noticeably slows during clipping where it did not before, charge the battery
pack.
5. A new battery pack may not charge to full capacity on the first use. This is normal and does not
indicate a problem with the battery pack or charger. About five cycles of using the clipper until
the motor slows, and then recharging until the charger indicates “charging complete” will bring
the battery pack to full capacity. This is called “forming” a battery pack.
6. Under normal room temperature conditions, there is no need to allow the charger base to cool
between charging battery packs. Completely discharged battery packs may be returned to the
charger base continuously for fast charge. If the room temperature is very warm however,
allowing the charger to cool 5 minutes between battery packs is advisable. If the charger has
become too hot internally, fast charge will be discontinued. Remove the battery pack and
replace after a 5 minute cooling period, the charger will reset automatically.
7. It is normal for the charger to become warm to the touch during operation.
