Operation And Adjustment - EINHELL BT-MR 550 Originalbetriebsanleitung

Anleitung_BT_MR_550_SPK7:_
parts can move easily.
Before you connect the machine to the power
supply, make sure the data on the rating plate is
the same as that for your mains.
Fit the supplied crank handles (Figure 5).
6.2 Installation
Set the machine up on a level base (workbench etc.).
Important: The machine must be screwed tight to
the base using four screws. To do this, use the four
fixing holes in the baseplate of the machine.
Make sure that there is enough space for the
compound table to traverse and for angle
adjustments.
You must also make sure that what is underneath
the machine is sufficiently stable to support the
weight (approx. 50 kg) of the machine!
All bare parts of the machine are already greased in
order to protect them from corrosion. Clean the
machine with a suitable environmentally friendly
cleaning agent before using it for the first time. Do
not use any cleaning agents that could attack the
paintwork of the machine and ensure sufficient
ventilation during cleaning. Lubricate the machine
with non-acidic lubricating oil again after cleaning.
Important: Oil, grease and cleaning agents are
harmful to the environment and must be disposed of
in an environmentally compatible way - not with
household rubbish!
6.3 Mains connection / switch
The machine may only be operated with single-
phase current 230 Volt / 50 Hz. The electric circuit of
the house must be protected by no more than a 16A
fuse.
6.3.1 Switching on the machine (Fig. 3/4)
First set the speed selector switch (6) to position "0".
If the Emergency Stop switch (8) is also activated
you will have to release the lock. The orange
indicator lamp (b) will go out. When the green
indicator lamp (a) lights up, the desired rotational
speed of the machine can then be set and the
machine will start up.
6.3.2 Switching off the equipment (Fig. 4)
Switch off the equipment by pressing the Emergency
Stop switch (8) and then unplug the power plug.

7. Operation and adjustment

Important: Always unplug the power plug before
making any adjustments to the machine.

7.1 Setting the rotational speed (Figs. 3-4)
Use the gear lever (5) on the machine side to choose
between two speed ranges.
Front position (L) for the rotational speed rang
0 to 1100 min
Rear position (H) for the rotational speed range
0 to 2500 min
Important: Do not change rotational speed ranges
(L and H) while the spindle is running! The rotational
speed can be adjusted infinitely within the speed
range. Use the speed selector switch (6) to finely
adjust the rotational speed.
7.2 Correct rotational speed / cutting speed
The choice of the correct cutting speed has an
enormous effect on the service life of the tool and on
the work results. The right speed depends on the
material. If the chosen rotational speed is correct, the
cutting speed will also be correct.
7.2.1 Drilling
Rule of thumb: The smaller the hole and the softer
the material, the higher the speed of rotation.
The table below will help you select the proper speed
for the various materials.
Note: The rotational speeds shown are merely
suggested values.
To adjust the speed, see chapter 7.1.
