Milwaukee Tool 6880 - Manual (Page 3)

4 5
Grounded tools require a three wire extension
cord. Double insulated tools can use either a two
or three wire extension cord. As the distance from
the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the
greater the capacity of the cord. For example, a 14
gauge cord can carry a higher current than a 16
gauge cord. When using more than one extension
cord to make up the total length, be sure each cord
contains at least the minimum wire size required.
If you are using one extension cord for more than
one tool, add the nameplate amperes and use the
sum to determine the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors, be
sure it is marked with the suffi x “W-A” (“W” in Cana-
da) to indicate that it is acceptable for outdoor use.
• Be sure your extension cord is properly wired
and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a
qualifi ed person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.
READ AND SAVE ALL
INSTRUCTIONS FOR FUTURE USE.
* Based on limiting the line voltage drop to fi ve volts at
150% of the rated amperes.

ASSEMBLY
WARNING To reduce the risk of injury,
always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.
Punch and Die Replacement
Dies should be replaced about every third time the
punch is changed, or as necessary. A plate wrench
is provided with tool.
1. Unplug tool and place on a level surface.
2. Loosen collar with plate wrench. Remove collar
and die support.
3. Punch Removal: Loosen the set screw with 2.5
mm allen wrench. Remove punch and discard.
4. Punch Installation: Align punch detent with set
screw in punch holder. Tighten set screw se-
curely to below the surface of the punch holder.
5. Die Removal: Remove cap screws and lock-
washers with 2.5 mm allen wrench. Discard die.
6. Die Installation: Place die in position. Screw
holes in die and die support will align when die
is properly seated. Replace cap screws and
lockwashers and tighten securely.
7. Position die support in desired direction of cut
using locating pin. Replace collar and tighten
securely.

Grounded Tools: Tools with Three Prong Plugs
Tools marked “Grounding Required” have a three
wire cord and three prong grounding plug. The
plug must be connected to a properly grounded
outlet (See Figure A). If the tool should electrically
malfunction or break down, grounding provides a
low resistance path to carry electricity away from
the user, reducing the risk of electric shock.
The grounding prong in the plug is connected
through the green wire inside the cord to the
grounding system in the tool. The green wire in the
cord must be the only wire connected to the tool's
grounding system and must never be attached to
an electrically “live” terminal.
Your tool must be plugged into an
appropriate outlet, properly installed
and grounded in accordance with
all codes and ordinances. The plug
and outlet should look like those in
Figure A.
Double Insulated Tools:
Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require
grounding. They have a special double insulation
system which satisfi es OSHA requirements and
complies with the applicable standards of Underwrit-
ers Laboratories, Inc., the Cana-
dian Standard Association and the
National Electrical Code. Double
Insulated tools may be used in ei-
ther of the 120 volt outlets shown in
Figures B and C.

GROUNDING
WARNING Improperly connecting the
grounding wire can result in the risk of elec-
tric shock. Check with a qualifi ed electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug
provided with the tool. Never remove the
grounding prong from the plug. Do not use
the tool if the cord or plug is damaged. If
damaged, have it repaired by a MILWAUKEE
service facility before use. If the plug will not
fi t the outlet, have a proper outlet installed by
a qualifi ed electrician.

Punch and Die Replacement (Cat. No. 6880)
Punch and die should be changed as a set. A 4
mm allen wrench is required to remove and tighten
screws in punch, die and stripper. All screws, wash-
ers, lockwashers and plastic cap removed during
servicing will be required for reassembly.
1. Unplug tool and place on a level surface.
2. Stripper Removal: Remove screws, fl at wash-
ers, lockwashers and stripper.
3. Die Removal: Remove screws, lockwashers and
die. Discard die.
4. Punch Removal: Remove plastic plug and insert
screwdriver in slot at end of spindle shaft. Rotate
shaft until punch retaining set screw is visible
through hole in rear of die holder. Remove set
screw and punch. Discard punch.
5. Punch Installation: To install new punch, align
punch with "D" slot. The punch is to be inserted
until it bottoms in hole. Replace set screw and
tighten securely. Replace plastic cap in gear case.
6. Die Installation: To install new die, align screw
holes in die with holes in die holder. Replace
lockwashers and screws and tighten securely.
7. Stripper Installation: To replace stripper, align
screw holes in stripper with holes in die holder.
Replace lockwashers, fl at washers and screws.
Adjust stripper (refer to Stripper Adjustment
under 'Operation'). Tighten screws securely.
If there are any problems with removal or instal-
lation of punch and die, contact your nearest
MILWAUKEE service facility. Return tool and parts
to that facility, if necessary.
Side Handle (Cat. No. 6880)
Unplug the tool before installing or removing the side
handle. The side handle can be attached to either
side of the gear case for right or left handed operation.
