1050 mm, or 13 for sawing width 1500 mm)] onto cast iron machine table as per machine making.
Table enlargement is supported by consoles (12), and making 1500 mm is supported by supporting
legs (23).
- slip a longitudinal ruler holder with ruler (10) over the right edge (11) of the guiding bar
- as per a machine making do mount the saw blades guard (22) and exhausting hose holder (21),
or the arm (6) of parallelogram and the saw blades guard (5). A narrow rear guard for sawing with
upright saw blade, or an extended rear guard for sawing with a tilted saw blade, can be mounted onto
saw blades guard (22).
- do mount a metal sheet enlargement (7) onto the rear side of machine cast iron table.
7 Connecting of exhaustion
An exhausting unit of a minimum air stream speed in the hose 20 ms
-1
for dry particals,
and a minimal air stream speed in the hose of 28 ms
-1
for wet particals, is necessary
for a proper functioning of the machine.
Always operate machine only with running exhausting !
Start the machine and the exhausting unit all at once !
Use a flexible exhausting hose of diameter 100 mm for connecting to the lower (A) exhaustion outlet
branch. Connect the upper (B) exhaustion by a flexible hose Ø 40 mm (saw blades guard carried by
riving knife) or (C) hose Ø 100 mm (saw blades guard carried by an arm - parallelogram).

8 Connecting to mains
Only an electrotechnically qualified person, cognizant of rated
norms, can connect the machine to the mains.
8.1 Connection to mains
Make sure that no voltage is at the supply
lead before connecting. Unscrew the cover
of the terminal board (A), put the
connecting cable through - into the box with
the termi-nal board and connect individual
phase conductors with corresponding
clamps. Connect the protective conductor
(yellow-green) to the clamp PE and the
central conductor (pale blue) to the clamp
N, if requi-red. Cross-sections of phase
conductors and of the protective conductor
must be conformable with legal standard
norms. Check up accuracy of connecting
and fasten the terminal cover with screws
again.
8.2 Safety of operation
Damaged supplying lead must be replaced immediately by a
competent specialist. Machine run with damaged supply cables
is dangerous to life and therefore forbidden.
Before establishing the machine to the run make sure that the voltage and frequency stated on the
machine rating plate answer to those of supplying mains.
Every machine must be connected to mains according to regulations. It must be secured by 16 A fuses
at least ,or by an L-type circuit braker for electric motors power 3 and 4 kW, and at least by 25 A fuses
or by an L-type circuit braker for electric motor power 5,5 kW.
Always switch off the main switch and lock it or disconnect
the machine by towing the plug from the socket before tools
adjusting and replace and all adjusting, treatment and
maintenance works. Herewith you avoid an unfought starting
of machine by an else person.
