a fixed structure by fastening the strap through the opening (Fig. 5a, 5b) or to the
carrying handle when working in horizontal position (Fig. 5c). The strap must be tight,
not twisted, and must be replaced every single time the machine hangs on
the strap
as a result of coming loose
from steel.
Never insert the strap into the buckle from the
front (Fig. 5d).
Fig. 5.
Protecting the machine from falling by using the safety strap
Rotate the handles to the left to place the tool above the workpiece.
When working in the position from Fig. 5a, fill the cooling system bottle with
coolant. Do not use only water as the coolant. However,
using
emulsions
from water
and drilling oil is adequate. To check the operation of the cooling system, slightly
loosen the bottle cap, use the lever to open the valve, and then rotate the handles to
the left to initially apply pressure on the pilot pin. The coolant should fill the system
and start flowing from the inside of the cutter.
Because
the
cooling
system
works
by
gravity,
when
working
in inverted or horizontal
positions (Fig. 5b, 5c) use coolants under pressure or in the form of spray or paste.
