OPERATION
To reduce the risk of injury, always
WARNING
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.
Water Connection
A water connection is available on the machine for
use with all types of water supply. Wet cut whenever
possible; water cools the wheel (increasing its ser-
vice life) and reduces the formation of dust. Follow
all instructions and warnings provided by the wheel
manufacturer for wet cutting. Due to the electronic
water valve, water will only flow when the valve is in
the on position and the trigger is pulled.
Arming the Machine
The MX FUEL™ machines must be armed prior to
use. Even with the battery pack inserted, the trig-
ger and machine functions will not operate until the
machine is armed.
To arm the machine:
1. Insert the battery pack.
2. Press the arm button. The MX FUEL™ icon will
light. The trigger will become armed in 2 seconds.
3. After 10 minutes of inactivity, the machine will enter
sleep mode. The MX FUEL™ icon will go off and
the trigger and LEDs are un-operational.
4. Press and hold the arm button for 1 second to
reactivate the machine.
5. Press and hold the arm, button for 1 second to
unarm (turn off) the machine. The MX FUEL™
icon will go off.
ECO-Coach LED
Always monitor the ECO-Coach LED during opera-
tion for optimal performance.

Making a Cut
1. Insert the battery pack.
2. Arm the machine.
3. Squeeze the lock-off lever and pull the trig-
ger. Allow the machine to reach full speed and
then slowly lower the wheel into the workpiece.
NOTE: Always start the cut gently pushing the
wheel through the workpiece. Do not bang or bump
a wheel when starting or during a cut. Always push
the machine away from you.
4. While cutting, maintain a firm grip. Do not force
the cut-off machine through the work. Forcing a
cut-off machine can cause kickback.
5. Always monitor the ECO-Coach LED while cutting.
6. When the cut is finished, always allow the wheel
to come to a complete stop. Never remove the cut-
off machine from a cut while the wheel is moving.
7. If making a partial cut, restarting a cut or cor-
recting cut direction, allow the wheel to come
to a complete stop. To resume cutting, center
the wheel in the kerf (cutting slot), back the
wheel 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.
