OPERATION
Correct use of the tool
Die selection
It is important that the die to be used is correct for the thick-
nessoftheworkpiecetobepunched.Punchingtheworkpiece
of 4 mm to 8 mm thickness using a die for thinner workpiece
cancausethepunchtojamintheworkpiece.Thisisdueto
the smaller clearance between the die and punch. In such a
case,theworkpiecewillbepulledupbytheretractingpunch
asshowninthegure.Specialcareshouldbetakenwhen
punchingatbarofmildsteel,aluminumandcopper.
►Fig.10: 1. Workpiece
Correct use of the stripper
Do not position the workpiece with one end or both
endsunsupportedbythestripper.Iftheworkpieceisnot
properlysupported,itwillmovewhenthepunchreturns.
Itmaycausethepunchtojamanddamagingthetool.

4. Checkthatthepunchpistonisfullyretracted.
5. Placethepuncherintherequiredpositiononthe
workpieceusingtheslidestopperasaguide.Alignthe
point of the punch with the center mark of the hole to be
punched.
6. Continue to pull the switch trigger until the punch
reaches the end of its stroke and returns to the starting
position.
The punch rod will extend and push the punch through
the workpiece.
NOTE:Toaidaccurateandeasypositioningofthe
punch,pulltheswitchtriggerintermittentlytojogthe
punch down to the workpiece. If the position is not
satisfactory,openthereturnlevertoretractthepunch
for another attempt. If the punch doesn’t return to its
starting position with return lever open, pull the switch
trigger to return the punch.
NOTE: If the punch doesn’t return after punching
nishes,releasetheswitchtriggertostopthemotor
and pull the switch trigger again.
If the punch doesn’t return even after performing
above procedures, perform the procedures for stop-
ping the operation before the completion of punching
mentioned below.
Stopping the operation before the
punching is nished
Ifyouwanttostoptheoperationbeforethepunchingis
nished,performtheproceduresbelow:
1. Turn the return lever counterclockwise until it hits
thespringpinandthenimmediatelybacktoitsstarting
position.
Doing this releases the internal pressure of the tool. If
the punch retracts from the workpiece under its own
power,allowthepunchtofullyreturn.Afterthat,turnthe
return lever back to its starting position. In this case, the
followingstepisnotnecessary.
2. Continue to pull the switch trigger until the punch
returns to its starting position.
