Terratek Hedge Trimmer, charger and batteries - faulty (St Pauls Ward GU15)

Terratek Extendable Pole Hedge Trimmer. Has an intermittent fault, I believe it needs taking apart, the blades sharpening and oiling, then putting back together and it should work. Comes with the charger and two batteries 20V 1500aMh. Charger and batteries in full working order so they may be useful also if you have another Terratek device.
