GROUNDING
Improperly connecting the ground-
WARNING
ing wire can result in the risk of
electric shock. Check with a qualified electrician
if you are in doubt as to whether the outlet is
properly grounded. Do not modify the plug pro-
vided 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 fit the outlet, have a
proper outlet installed by a qualified electrician.
Grounded Tools (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 mal-
function 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 appro-
priate 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 (Two-Prong Plugs)
Tools marked "Double Insulated" do not require
grounding. They have a special double insulation
system which satisfies OSHA requirements and
complies with the applicable standards
of Underwriters Laboratories, Inc., the
Canadian Standard Association and
the National Electrical Code. Double
Insulated tools may be used in either
of the 120 volt outlets shown in Figures
B and C.

rotating or while the bit is falling from the chuck.
Installing Drill Bits and Chisels
Only use accessories with SDS or SDS+ shanks.
Be sure that the shank of the bit is clean. Dirt particles
may cause the bit to line up improperly. Do not use
bits larger than the maximum recommended capacity
of the drill because gear damage or motor overload-
ing may result. For best performance, be sure that
the bit is properly sharpened and the shank is lightly
greased before use.
1. Insert the bit or chisel into the nose of the tool.
2. Rotate bit slowly until it aligns with the locking
mechanism.
3. Push bit into tool until it locks.
4. Check that the bit is locked
properly; it should be possible to
pull the bit back and forth slightly
(about 1/4").
5. To remove bits and chisels, pull
bit holder release collar toward
the rear of tool and remove
bit.
NOTE: Use caution when handling hot bits and
chisels.
WARNING
removing accessories or making adjustments.
Use only specifically recommended accessories.
Others may be hazardous.
Always wear proper eye protection marked to
comply with ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
Keep hands and cord away from the bit and all
moving parts.
Always use a side handle when using this tool.
Always brace or hold securely.
These MILWAUKEE Rotary Hammers have two set-
tings: rotation only and rotary hammering.
