If your rechargeable Vision 180 Trimmer does not seem to take a charge, check the following before returning it for repair: Check outlet current by plugging in another appliance. Make sure the outlet simply is not connected to a light switch which turns the power at the outlet off when lights are turned off. Be sure the trimmer is properly connected to the recharging transformer, all connections are secure and the switch on the trimmer is turned "O" OFF. f your electricity is connected to a master power switch, we suggest the trimmer be disconnected from the charger anytime the master switch is off. Leaving the unit plugged into a dead outlet or an unplugged charger will drain the battery. If trimmer does not run and it is completely charged, turn the unit "l" ON and pinch or push the blades manually. (Oil may have dried out between blades, so they may be temporarily stuck together.) If the light bulb fails do not attempt to replace it. It may be replaced by the Wahl repair department. DISPOSAL/REPLACEMENT OF NI-CD BATTERY CONTAINS SEALED, RECHARGEABLE NICKEL-CADMIUM BATTERY.
