Preventing Kickback
Kickback is the sudden reaction to a pinched wheel
which could cause a cut-off machine that is not under
control to lift up and out of the workpiece towards
the user. Take the precautions below to help prevent
kickback.
1.
Maintain a firm grip and correct body position.
Position arms and body to control the backward
and upward reaction force of kickback. Control the
cut-off machine at all times.
2.
Set the depth of cut for no more than neces-
sary.
The less wheel exposed, the less chance of
binding and kickback. Before cutting, be sure shoe
assembly is tight.
3.
Always allow the wheel to come to a full stop
before removing the cut-off machine from the
workpiece.
Never remove the cut-off machine
from a cut while the wheel is moving. If restarting or
correcting direction in mid-cut, allow the wheel to
coast to a stop, back the cut-off machine up a few
inches and center it in the kerf before restarting.
4.
Stay alert.
Any distraction can cause twisting
or binding. Repetitive cuts may lull the user into
careless movements.
5.
Do not force the tool.
Forcing a cut-off machine
reduces control and cutting efficiency.
If kickback should occur, continue to grip the cut-off
machine firmly and immediately release trigger.
Wheel Selection
WARNING
To reduce the risk of injury, only
use Type "1" abrasive and diamond
cutting wheels with at least 1/8" thickness which
is rated with a maximum safe operating speed
at least 5400 RPM. Read safety information sup-
plied with cut-off wheel.
Non-metallic Materials
When cutting non-metallic materials, use a silicone
carbide abrasive cut-off wheel of at least 1/8" thick
-
ness which is rated with a maximum safe operating
speed at least 5400 RPM.
READ SAFETY INFOR-
MATION SUPPLIED WITH CUT-OFF WHEEL.
Always wear proper safety equipment, including a
dust mask.
Metallic Materials
When cutting metals, use an aluminum oxide abra-
sive cut-off wheel of at least 1/8" thickness which is
rated with a maximum safe operating speed at least
5400 RPM.
READ SAFETY INFORMATION SUP-
PLIED WITH CUT-OFF WHEEL.
Protect everyone
in the area from sparks.
Masonry Materials
When cutting masonry materials, use dry diamond
wheels or silicone carbide abrasive cut-off wheel of
at least 1/8" thickness which is rated with a maximum
safe operating speed at least 5400 RPM.

SAFETY INFORMATION SUPPLIED WITH CUT-
OFF WHEEL.
Always wear proper safety equipment,
including a dust mask.
Making a Cut
1. Unplug tool. Select a cutting depth and adjust the
height of the shoe assembly as described in “Adjusting
the Depth of Cut”.
2. Plug the tool in and pull the trigger. Allow the mo
-
tor to reach full speed and then slowly lower the
wheel into the workpiece.
NOTE:
Always start the cut gently pushing the saw
through the workpiece. Do not bang or bump a
wheel when starting or during a cut. Always push
the saw away from you
3. While cutting, keep the shoe flat against the
workpiece and maintain a firm grip. Do not force
the cut-off machine through the work. Forcing a
cut-off machine can cause kickback.
Make repeated passes at depths of less than 1/2"
to achieve the desired depth. Cutting at a depth of
more than 1/2" will damage the wheel. Frequently
clean dust from air vents and guards.
4. When the cut is finished, always allow the motor to
come to a complete stop. Never remove the cut-off
machine from a cut while the wheel is moving.
5. If making a partial cut, restarting a cut or correct
-
ing cut direction, allow the wheel to come to a
complete stop. To resume cutting, center the wheel
in the kerf (cutting slot), back the saw away from
cutting edge a few inches, pull the trigger and re-
enter the cut slowly.
NOTE:
If the cut-off machine stalls, maintain a firm
grip and release the trigger immediately. Correct
the problem before continuing.
Overload Protector
To protect the motor from damage, the overload pro-
tector automatically turns off the tool when the motor
is overloaded. The tool can become overloaded when
cutting material that is too thick or cutting materials
too quickly. To prevent the overload protector from
activating, always follow the cutting instructions un-
der the "Operation" section. Do not attempt to defeat
or override the overload protector.
If the tool turns off automatically:
1. Release the trigger and unplug the tool.
2. Remove the wheel from the workpiece.
3. Allow the tool to rest for a miniumum of two minutes.
4. Reset the overload protector by pushing in the
button.
5. Allow the tool to run under no load to ensure the
tool has properly cooled.
6. Resume the cut. When restarting a saw in the
workpiece, center the saw wheel in the kerf, or
cut, and check that the wheel is not engaged into
the material. If saw wheel is binding, it may walk
up or KICKBACK from the workpiece as the saw
is restarted.
MAINTENANCE
WARNING
To reduce the risk of injury, always
unplug the tool before performing
any maintenance. Never disassemble the tool.
Contact a MILWAUKEE service facility for ALL
repairs.
Maintaining Tools
Keep your tool in good repair by adopting a regular
maintenance program. Inspect your tool for issues
such as undue noise, misalignment or binding of
moving parts, breakage of parts, or any other condi-
tion that may affect the tool operation. Return the tool
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool to a MILWAUKEE service facility for inspection.
WARNING
To reduce the risk of personal in-
jury, electric shock and damage,
never immerse your tool in liquid or allow a liquid
to flow inside it.
