Installing Drill Bits and Chisels
Only use accessories with SDS or SDS Plus shanks.
Be sure that the shank of the bit is clean. Dirt par-
ticles 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 mo-
tor overloading 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 chis-
els.
OPERATION
WARNING
To reduce the risk of injury,
keep hands and cord away from the bit
and all moving parts.
WARNING
To reduce the risk of injury,
wear safety goggles or glasses with side
shields.
WARNING
To reduce the risk of injury,
always unplug tool before attaching
or removing accessories or making adjust-
ments. Use only specifi cally recommended
accessories. Others may be hazardous.
Reverse
Forward
Selecting Action
These
MILWAUKEE
Rotary Hammers have
three settings: drill only, rotary hammer, and
hammer only. Always allow the motor to
come to a complete stop before changing the
mode selection to avoid damage to the tool.
1. For drilling, press in the
selector release button and
turn the selector lever so the
arrow on the lever points to
the twist drill symbol.
2. For rotary hammering, press
in the selector release but-
ton and turn the selector
lever so the arrow points to the hammer and
twist drill
symbol.
3. For hammering only, press in the selector release
button and turn the selector lever so the arrow
points to the hammer
symbol.
4. To freely rotate the bit to the desired angle for
hammering only, press in the selector release
button and turn the selector lever to the
symbol. Then, follow step 3.
NOTE:
To engage the hammering mechanism,
maintain pressure on the bit. When pressure on
the bit is released, the hammering action will stop.
Using the Control Switch
Always allow the motor to
come to a complete stop be-
fore using the control switch.
For
forward
(clockwise) rota-
tion, push the control switch
to the left side of the tool.
Check the direction of rotation
before use.
For
reverse
(counterclock-
wise) rotation, push the con-
trol switch to the right side of
the tool. Check direction of
rotation before use.
Starting, Stopping and Controlling Speed
1. To
start
the tool, grasp the handle fi rmly and pull
the trigger.
2. To
vary
the speed, increase or decrease the
pressure on the trigger. The further the trigger
is pulled, the greater the speed.
3. To
stop
the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Lock-On
The lock-on button holds the trigger in the ON posi-
tion for continuous full speed use.
1. To lock the trigger, hold in the lock button while
pulling the trigger. Release the trigger.
2. To unlock the trigger, pull the trigger and release.
The lock button will pop out.
Operating
Position the tool, grasp the handles fi rmly and pull
the trigger. Always hold the tool securely using
both handles to maintain control. This tool has
been designed to achieve top performance with
only moderate pressure. Let the tool do the work.
If the speed begins to drop off when drilling large
or deep holes, pull the bit partially out of the hole
while the tool is running to help clear dust. Do not
use water to settle the dust since it will clog the bit
fl utes and tend to make the bit bind in the hole. If
the bit should bind, a built-in, non-adjustable slip
clutch prevents the bit from turning. If this occurs,
stop the tool, free the bit and begin again.
MAINTENANCE
WARNING
To reduce the risk of injury,
always unplug your tool before per-
forming any maintenance. Never disas-
semble the tool or try to do any rewiring
on the tool’s electrical system. Contact a
MILWAUKEE service facility for ALL repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Before use, examine the gen-
eral condition of your tool. Inspect guards, switches,
tool cord set and extension cord for damage. Check
for loose screws, misalignment, binding of moving
parts, improper mounting, broken parts and any
other condition that may affect its safe operation. If
abnormal noise or vibration occurs, turn the tool off
immediately and have the problem corrected before
further use. Do not use a damaged tool. Tag damaged
tools “DO NOT USE” until repaired (see “Repairs”).
Under normal conditions, relubrication is not neces-
sary until the motor brushes need to be replaced.
After six months to one year, depending on use,
return your tool to the nearest
MILWAUKEE
service
facility for the following:
• Lubrication
• Brush inspection and replacement
• Mechanical inspection and cleaning (gears,
spindles, bearings, housing, etc.)
• Electrical inspection (switch, cord, armature, etc.)
• Testing to assure proper mechanical and electri-
cal operation
WARNING
To reduce the risk of injury,
electric shock and damage to the tool,
never immerse your tool in liquid or allow a
liquid to fl ow inside the tool.
Cleaning
Clean dust and debris from vents. Keep the tool
handles clean, dry and free of oil or grease. Use
only mild soap and a damp cloth to clean your tool
since certain cleaning agents and solvents are
harmful to plastics and other insulated parts. Some
of these include: gasoline, turpentine, lacquer thin-
ner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing
ammonia. Never use fl ammable or combustible
solvents around tools.
Repairs
If your tool is damaged, return the entire tool to the
nearest service center.
