All cords should be secured at least 25 mm
away from any moving parts. Furthermore, do
not excessively bend the cords or secure them
too firmly with staples, otherwise there is the
danger that fire or electric shocks could occur.
¡
Install the belt covers to the machine head and
motor.
¡
If using a work table which has casters, the
casters should be secured in such a way so that
they cannot move.
¡
Be sure to wear protective goggles and gloves
when handling the lubricating oil, so that no oil
gets into your eyes or onto your skin, otherwise
inflammation can result.
Furthermore, do not drink the oil under any cir-
cumstances, as it can cause vomiting and di-
arrhoea.
Keep the oil out of the reach of children.
