Changing Gears
The EBM 300/3 P is equipped with a mechanical 3-speed oil-bath
gearbox.
Select the speed according to the drilling diameter (ref. to the tool's
identification plate).
Use the speed selection to change to the next higher or lower speed until
it locks. Change the speed only when the tool is not running; slightly turn
the working spindle to ease the speed change.
Warning!
!
Never apply force and change the gear only when the
machine is running down.
Never use tools, such as hammers or pliers to change
the gear.
Drill Bit Changing
Attention!
The machine is heavy and when you use or sharpen it, it might heat
up enormously. You could burn your hands or get cut or ripped by
the segments. Before the beginning of all works on the tool you have
to disconnect the plug from the mains. Always use protective gloves
when changing the drill bit.
The drill spindle has a right-hand thread.
To hold on spindle always use an jaw wrench SW 32.
Never remove the drill bit with impacts because this way the machine will
be damaged.
With some waterproof grease, which is put on the drill bit thread, and a
copper ring between spindle and drill bit you can remove the drill bit
easier.
