ing, otherwise the machine may operate if the
treadle is pressed by mistake, which could result in
injury.

turning even after the power is switched off as a
result of the motor's inertia. Wait until the motor
stops fully before starting work.

tilting it back or returning it to its original position. If
only one hand is used, the weight of the machine
head may cause your hand to slip, and your hand

Furthermore, do not drink the oil under any circum-
stances, as they can cause vomiting and diarrhoea.
Keep the oil out of the reach of children.
