OPERATION
WARNING
To reduce the risk of injury, 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.
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.
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 and hold the Arm button for about 2 sec-
onds. The MX FUEL™ icon will light, and the
trigger and LEDs are now operational.
3.
After 15 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.
Making a Cut
1. Install battery pack.
2. Press the arm button.
3. Move the trigger lock and pull the trigger. 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. Frequently
clean dust from air vents and guards.
5. 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.
6. If making a partial cut, restarting a cut or correcting
cut direction, allow the wheel to come to a com-
plete 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.
Overheat Indicator
To protect the machine from damage, the overheat
protection automatically turns off the machine when
the machine overheats. The overheat indicator
will blink for 5 seconds. The machine can become
overheated when cutting materials too quickly. To
prevent the overheat protection from activating,
always follow the "Making a Cut" instructions in the
"Operation" section.
If the machine turns off automatically:
1. Release the trigger.
2. Remove the wheel from the workpiece.
3. Allow the machine to rest.
4. Run the machine under no load to ensure the
machine has sufficiently cooled before beginning
work.
MAINTENANCE
WARNING
To reduce the risk of injury, always
unplug the charger and remove the
battery pack from the charger or machine before
