Warning
A workshop often has a range of electrical tools at the workplace. It is not uncommon for the
wrong contact to be connected to the mains – perhaps to the very machine you are working with!
A simple way of highlighting this and preventing unintentional connections is to tape over the
contact pin.
Note: A machine that has been dismantled must not be connected to the
mains supply. Functional tests must not, and do not need to be made on a dismantled
machine that is connected to the mains.

Work tip
The easiest and most convenient way of executing
virtually all service work on the DM330/DM340 is with
the machine in a vertical position with the drill spindle
facing downwards.
Do it yourself
A fixture for securing the machine in a vice is easily
made using a wood block and a pair of steel plates.
The wood block should be at an equal height to the
drill spindle, about 2 1/2 in. (55 mm). Drill a hole with
a diameter of 1 1/4 inches, corresponding to around 32
mm, in the block.
The two steel plates secure the wood block horizon-
tally in the vice.
It is even easier to drill a hole in the work bench.
