Kompernass PTBM 350-13 - Manual (Page 6)

INSTALLATION AND FIRST USE
Check that the supply type, voltage and fuses comply with those specified for the machine.
First clean any anti-rust coating carefully from the parts. Then oil the column.
SWITCHING THE MACHINE ON AND OFF
Insert the plug into the mains socket and switch on the machine using the "I” button at the
on/off switch
º . To switch off use the “0” button.
CHECKING AND TENSIONING THE V-BELT
Open the drive/belt cover ¸ and check the V-belt tension. If it is correctly adjusted the V-belt
should be able to be moved approximately 1 cm in the middle between the two drive wheels.
Loosen the adjustment screw
Ƹ and press the motor unit ¶ backwards before retightening the
adjustment screw Ƹ .
SETTING THE SPEED
The bench drill has 5 different speeds. The speed is set by simply repositioning the V-belt. To do
this open the drive/belt cover
¸ , loosen the adjustment screw Ƹ and place the V-belt on the
relevant pair of drive wheels.
Note: The top pair give the highest speed; the bottom pair the lowest (
ቢ =2600, ባ = 1750,
ቤ = 1250, ብ = 900, ቦ = 600, see figure on page 3).
Then tension the V-belt as described in the section on “Tensioning the V-belt”.
Note: Inside the drive/belt cover
¸ there is a contact which must come together with an opposing
contact (see ƻ ) on the drive/belt casing base when the drive cover is closed. The motor can only
be restarted if the drive/belt cover ¸ is properly closed.
SETTING THE DRILLING TABLE
The drilling table » can be adjusted by loosening the table clamp screw ƺ .
Set the table so that there is an adequate distance between the workpiece top surface
and the drill bit point.
The table can be swung to the side, e.g. when you wish to work on a tall workpiece that can be
attached directly to the base plate.
DEPTH STOP / DRILLING TO AN EXACT DEPTH
The depth stop with its scale ƾ allows you to drill to an exact depth.
First of all press lightly down on to the top of the workpiece surface using the handle ƹ and set
the drilling depth using the adjustment nut ƿ on the scale.
Note: Make sure that you take into account the length of the drill bit point (normally approx.
5 mm) when determining the appropriate setting for the cylindrical part of a drilled hole.
INCLINED DRILLING
The drilling table » can be rotated to drill angle holes or to accommodate workpieces
with inclined ends. Release the hexagonal socket screws on the drilling table swivel joint.
Place the table at the required slope and retighten the hexagonal socket screws.
