3. MAINTENANCE AND CLEANING
3.1. General maintenance
The NF70 NARGESA forging machine has been conceived and designed to be almost maintenance free.
The only point to note regarding maintenance is the level of lubricant of the gearbox. This level may be ob-
served through the inspection peephole (1) visible in the side of the case, once the rear protection has
been disassembled.
In the event that the level is low, fill it up with oil SAE 80-140 by the filler hole (2) until oil is visible through
the peephole (1) (about half of the sight glass). A review of this parameter must be carried out at least once
every 3 months.
3.2. Cleaning
The machine NARGESA NF70 is designed to work with hot material (forged), which involves a large
amount of slag, chaff, etc is generated. during regular work. For the operator’s comfort, the NF70 has a
collector drawer at the bottom of the working area, wherein said slag falls, so it is advisable to periodically
empty it.

4. INSTALLMENT AND STARTINGUP
4.1. Location of the machine
The NF70 NARGESA machine will be positioned on a flat surface so it can be leveled. If desired, it can be
clamped to the ground through the holes made in the base for this purpose.
4.2. Working site
To use the forging machine NARGESA NF70 is essential to have enough space to work on the side of it
and also have access to the back to carry out the maintenance of the machine.

INSTRUCTIONS BOOK FOR THE END WROUGHT IRON MACHINE NF70 10
4.3. Admissible outer conditions
The working conditions of the machine NF70 NARGESA ranges between +5 º C and +50 º C and the maxi-
mum continuous temperature +45 ° C (24 hours)
The condition of humidity ranges between 30% and 90% non-condensing.
4.4. Electric connections
The machine NARGESA NF70 is designed to be connected to an outlet of a three-phase 230/400V
50/60Hz
NOTE: If voltage changes it will be necessary to change the protection of the electric motor according to
the following table:
Star shape
(preset)
For tension 400V
Triangular shape
For tension 230V
TENSION MOTOR PROTECTION
230 V 16 - 24 A
400 V 9 - 13 A
