Cold Starting - Milwaukee M18 FUEL Manual Del Operador

Using the Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Always allow the motor
to come to a complete stop before using the control
switch to avoid damage to the tool.
1. For forward (clockwise) rotation, push in the con-
trol switch from the right side of the tool. Check
the direction of rotation before use.
2. For reverse (counterclockwise) rotation, push in
the control switch from the left side of the tool.
Check direction of rotation before use.
3. To lock the trigger, push the control switch to the
center position. The trigger will not work while
the control switch is in the center locked position.
Always lock the trigger or remove the battery pack
any time the tool is not in use.
Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle(s) firmly and
pull the trigger.
NOTE: An LED is turned on when the trigger is
pulled and will go off shortly after the trigger is
released.
2. To vary the speed, increase or decrease the pres-
sure 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.
Operating
Position the tool, grasp the handles firmly and pull
the trigger. Always hold the tool securely using both
handles to maintain control. This tool has been de-
signed to achieve top performance with only moder-
ate 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 flutes 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.

Cold Starting

If this tool is stored for a long period of time or
at cold temperatures, it may not hammer ini-
tially because the lubrication has become stiff.
To warm up the tool:
1. Insert and lock a bit or chisel into the tool.
2. Pull the trigger and apply force to the bit or chisel
against a concrete or wood surface for a few
seconds. Release the trigger
3. Repeat until the tool starts hammering. The colder
the tool is, the longer it will take to warm up.
Using Rotary Percussion Core Bits
Core Bits are useful for drilling large or long holes
in concrete. MILWAUKEE Heavy-Duty Core Bits
have heat-treated steel bodies with durable carbide
tips. These core bits are specially designed for fast,
accurate drilling with combined hammering and
rotary action.
1. Clean and lubricate the
threads on the adapter
and core bit to make
later removal easier.
Thread the adapter
shank to the rear of the
core bit.
2. Push the guide plate
onto the pointed end of
the center pin. Insert the
center pin and guide
plate assembly into the
core bit. Be sure the
small end of the center
pin is securely placed
into the hole in the cen-
ter of the core bit.
For LHS systems, screw
the threaded end of the
centering bit into the core bit.
NOTE: If using an extension, first thread the
adapter shank to the extension. Then thread the
core bit to the extension.
3. Insert the adapter into the nose of the tool as
described in "Installing Bits and Chisels". Set the
knob to the "hammering with rotation" setting.
4. Press the centering bit firmly against your center
mark, hold the tool firmly and pull the trigger.
NOTE: If the 48-20-5099 threaded stud is used,
or a center pin and guide plate are not available,
use a template or notched board to start the hole.
5. Start the tool. After drilling to about the depth
of the core bit teeth, remove the center pin and
guide plate from the core bit (not necesary for LHS
system). Resume drilling.
6. To change the core bit, hold the tool upwards,
pointing it away from your body, and run it briefly
in forward to loosen the core bit from the adapter.
NOTE: To make deeper holes, remove the core bit,
break and remove the core, then resume drilling.
When drilling long or deep holes, after each inch
of penetration pull the bit partially out of the hole
while the tool is running, to help clear dust from
the bit flutes. Dust can clog the bit flutes and can
make the bit bind in the hole. If this occurs, stop
the tool, free the bit and begin again.
