cutting blade.
CHARGING ADVICE
After continuous or several repetitive charging cycles without interruption,
the charger can heat up. This is not harmful and does not indicate a technical
defect of the unit. A battery that is new or has not been used for a longer
period does not develop its full capacity until after approximately five charging/
discharging cycles. A significantly reduced working period after recommended
charging procedures, may indicate the battery needs replacing.
1. Connect the charger directly to the power receptacle.
2. Red LED is on: Battery is being charged.
3. Green LED is on: Charge process completed.
GENERAL INSTRUCTIONS REGARDING THE BATTERY

these instructions:
1. The lawn trimmer will be automatically switched off when the battery voltage is low. The

2. Always recharge the lithium-ion battery prior to any prolonged
period of nonuse.

2. Push in the direction of the arrow until it
snaps off the pivot.
3. Clean the pivot of any residual debris with a
sharp knife.
4. Refit the new blade by placing the eyelet over
the pivot and pull outwards until it
snaps into place.
