2.7. Electrical connection
Electrical parameters of the machine:
•
Service voltage: ~ 3×400 V, 50 Hz, TN-C-S
•
Total input / Max. fuse: 1,7 kW / 16 A
Before connecting switch off the main switch of the power supply circuit for the
machine and ensure dry place when doing connecting works!
Service voltage must agree with the line voltage! Crosscut of the supply line must respond
with rated current for max. machine load.
Connect the service cable of the machine on the clamps of the electric distribution.
In case the machine is connected with a direct connection, an extra main switch must
be added which can be locked in zero position.
2.7.1. Check the direction of the saw band
After the machine has been successfully connected, briefly switch on the machine and
put the driving engine of the band in the running position. The direction must be in
accordance with the arrow direction on the saw band cover. In case the direction of the
saw band does not match, two phases at the terminal strip must be switched.

Prepare the mixture of the water and the cooling liquid. Keep the concentration
specified by manufacturer. Shift away the cover from the drainage hole. Fill the mixture
of the water and the cooling liquid to the tank of the cooling system. Area of the tank
for the cooling liquid is discovered from the chapter
Technical data .
Let the drainage hole opened and with the sieve during operation, because it secures
the right work of the cooling system. Filling the tank with the cooling liquid, take care
that the liquid does not drip out of the tank and the tank does not overflowed.

The socket with the fork can be used only at the machines with
the rated current less than 16 A and total input less than 3 kW.
Attention!
In this case the extra main switch becomes primary and the
main switch on the machine has only secondary function.
