Before putting the machine into service
1) Safe operation of the appliance is only
possible if you have completely read the
operator's manual
2) Check the wear plate (73)
3) Check depth of immersion of the punch
4) The mains voltage must correspond to the
information on the machine type plate.
5) The mains Voltage must correspond with the
charger.
Advice for operation
Check tools hourly for wear.
Never work with blunt tools!
Otherwise the machine may be overloaded.
Do not approach the work piece with the
machine until the machine has been
switched on and reached maximum speed.
Cooling and lubrication
The cutting result is improved and the service life
of the punch increased if the cutting track is
coated with oil before machining the work piece.
Recommended for steel: Punching and nibbling
oil, order no. HW103387. Recommended for
aluminium: Wisura oil, order no. HW125874
Interior cut-outs
Interior cut-outs require a start hole of at least 24
mm Ø.
Changing the cutting direction
For right/left-hand operation or if a sectional
sheet is to be machined, the tool and cutting
direction can be turned to the right or left.
• Loosen screw (78).
• Turn extension holder to the cutting direction
needed 90° (67)
• Tighten screw (78) again.
Wear plate
The wear plate (73) protects the holder (79 or 69).
Check wear plate regularly and replace if worn.
Depth of punch
Turn screw on eccentric shaft ( 55 ) with screw
driver. At the same time check dipping depth of
punch. Punch should dip approx. 1.0 mm (.02
to .04 in) into die.
Retighten set screw after a short nibbling
distance.
When changing the punch, take care that
punch (65) is firmly screwed into punch
extension (67). The same applies to fastening
of punch extension (74) in connecting rod pin
(63). Screw in firmly punch extension (74) by
means of an 8 mm fork wrench.
The fine-pitch thread between the two
extensions may only be screwed in (68/74)
loosely. Here the depth of penetration of the
punch can be adjusted.
Care and Maintenance
Guarantee
Before working on machine disconnect from power
supply by removing plug from socket.
Always keep the machine and the ventilation slots clean.

3.
Maintenance
3.1
What points should be noted when operating
the profile nibbler?
a)
Always lubricate line of cut with of cut with oil in case of steel sheet and with kerosene in
case of aluminium sheet. If punching and nibbling oil (ordering No. 20198) is used, the
punch life can be increased when nibbling steel sheet.
b)
Check whether punch and die are sharp. Die must also be sharp on its face where it
supports the sheet.
Never nibble with blunt tools!
c)
The nibbler works more smoothly if it is slightly lifted during operation.
3.2
What should be done when the punch is blunt? A
a)
Undo set screw (78) approximately 4 turns.
b)
Withdraw tool head from housing.
c)
PN 4360 unscrew punch (65) from connecting rod pin (63).
PN 4361 unscrew punch (65) with its lower extension (68) from upper extension (74).
d)
Regrind face of punch (65) and bevel at the rear at longitudinal groove.
e)
Be careful that punch does not become shorter than the min. length (61 mm=2.44 in).
Shorter punches are unserviceable.
f)
Dress cutting edge slightly with oil stone.
g)
PN 4360 Screw punch into connecting rod pin.
PN 4361 Screw punch with its lower extension into upper extension.
h)
Slide tool head into housing (dismantle punch guide). Centre and secure with set screw
(78).
i)
Turn eccentric shaft (55) with screw driver. At the same time check dipping depth of
punch. Punch should dip approx. 1,0 mm (.02 to .04) into die.
k)
Retighten set screw after a short nibbling distance (78).
AK3161 B
When changing the punch, take care that punch (65) is firmly screwed into punch
extension (68). The same applies to fastening of punch extension (74) in connecting rod
pin (63). Screw in firmly punch extension (74) by means of an 8 mm fork wrench. See fig.
page B.
The fine-pitch thread between the two extensions (68,74) may only be screwed in loosely.
Here the depth of penetration of the punch can be adjusted (compare. 3.2,i).
3.3
What should be done when die is blunt? A+B
a)
Undo screws (72).
b)
Exchange old die for new one.
c)
