worktable in the vicinity of a grounded socket. The NL-33 v.3 Auto Maxi is connected to the power sup-
ply (230 V alternang current) with the supplied power cable. The NL-33 v.3 Auto Maxi is grounded and
equipped with two fuses type T 16 A. Place the power cord in the safety clip, which is mounted underneath
the power switch on the back of the machine, see below instrucon.
3.3 Pneumac installaon (2)
To be able to work with the NL-33 v.3 Auto Maxi without problems, it is very important that you work
