START-UP AND OPERATION
PBM-2000 comes in a ready to use state. The only operation that needs to be carried out is adjusting it to
the workpiece width and the beveling angle.
Plug machine into the power outlet. Both the plug and the socket must be grounded. Lift the machine and
place it vertically on its horizontal slide, on the edge of your workpiece, which should be on your right hand
side. Make sure that the tool does not touch the workpiece. You can now turn the machine on by pressing
the main switch (53) to position “I”. To switch machine off, press switch (53) to position “O”. You can now
start the motor by pressing switch (54, button “I”). Notice an amber light coming on (52). To stop the motor
press switch (54) again (button “O”).
Start sliding the machine slowly to the right, until such a moment that the tool starts to cut steel but remem-
ber – the direction of feed is marked on the spindle housing (9). The feed rate depends on the thickness
of steel which is being beveled and on the composition of that steel. Most common steels can be beveled
with just one pass.
It is recommended to bevel cuts above .5" (12 mm) width in 2 or 3 passes. Operator will put less
strength and time while performing multipass beveling.
If the operator attempts to mill too fast and too thick, the overload red indicator (51) will start flashing and if
the motor is overloaded even harder, power will be cut off. To start the machine again, move the tool away
from beveled edge, then press button “O” switch (54), and after a few seconds you can start the machine
again by pressing button “I” (switch 54).
The operator is permitted to use the machine at the brink of the cut-off point with overload light blinking, but
the temperature of the motor should not exceed 85°C. Higher temperature can permanently damage the
rotor. PBM-2000 is designed to work under full load for about one hour, after which it should cool down for
about 15 minutes. The motor will not cool down running free, but it will get even warmer.
REQUIRED ANGLE AND WIDTH OF CUT SETTING
There are two adjustment mechanisms:
-For adjusting the beveling angle required, (ß – see drawing 1),
-For adjusting the machine to the thickness of steel which is being cut, (b - see drawing 1).
Before you start any adjustments make sure that the machine is unplugged.
To change beveling angle loosen two M8 bolts (12) located on both sides of the Milling Head Housing (9)
and interlocking Vertical and Horizontal Slides. Then change position of the two slides, setting the required
angle according to the pitch marked on the side of the housing. After setting the right angle, tighten all bolts.
The width of cut can be set by turning Feed Bolt (7) which will change the position of the Milling Head. Do it
by loosening two levers (22) located on the side walls of the housing and turning the bolt (7). Then tighten
levers (22) . The pitch shown on the side of the housing gives only approximate parameters. Precise bevel-
ing width should be adjusted empirically by appropriate adjustment of the housing.
