The Deltalyo DAS6 Power+ Dual Action Polisher is a power tool and thus subject to a number of health and safety risks that should be fully understood from the outset; please read the supplied instructions carefully. General usage notes: (i) always wear earplugs and safety spectacles when using a machine polisher; (ii) always tie back long hair and tuck away anything else that could accidentally get caught up (e.g. necklaces or headphone cables); (iii) always switch off your machine at the mains before fitting or swapping the backing plate; (iv) always route the cable up and over your opposite shoulder so as to avoid it coming into contact with the car; (v) always ensure that the pad is in contact with the bodywork when you switch the machine on and off - if you don't do this it's likely to fly off at high speed; (vi) always familiarise yourself fully with the instructions provided for the pads and polishes you are using, and adjust your technique accordingly (e.g. tool speed, arm speed and pressure); (vii) always let the machine do the bulk of the work - there is rarely any need to exert heavy pressure when machine polishing (if the current pad and polish you are using aren't delivering sufficient cut, step up to a more aggressive combination rather than trying to force the issue); (viii) always take a break if you notice that the machine is becoming hot during use - hot machines tend to transmit heat down into the backing plate and pad, which can result in the pad failing prematurely; (ix) always lay the machine on its back when it's not in use, to prevent the pad coming into contact with the ground, and; (x) avoid stepping on the power cable at all times.
