General Operation - Milwaukee 6390-20 Manual Del Operador

• When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the
blade comes to a complete stop. Never attempt
to remove the saw from the work or pull the saw
backward while the blade is in motion or kick-
back may occur. Investigate and take corrective
actions to eliminate the cause of blade binding.
• When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade is binding, it may walk up or kickback from the
workpiece as the saw is restarted.
• Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the line
of cut and near the edge of the panel.
• Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf caus-
ing excessive friction, blade binding and kickback.
• Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
• Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.

General Operation

Always clamp the workpiece securely on a saw horse
or bench. See "APPLICATIONS" for the correct way
to support your work in different situations.
1. Draw a cutting line. Place the front of the shoe on
the edge of the workpiece without making blade
contact. Hold the Tilt-Lok™ handle with one hand
and the front handle with the other.
2. Line up the sight line with your cutting line. Posi-
tion your arms and body to resist KICKBACK. Pull
the trigger, allowing the motor to reach full speed
before beginning to cut.
3. While cutting, keep the shoe flat against the
workpiece and maintain a firm grip. Do not force
the saw through the workpiece. Forcing a saw can
cause KICKBACK.
4. If making a partial cut, restarting in mid-cut or cor-
recting direction, allow the blade to come to a com-
plete stop. To resume cutting, center the blade in
the kerf, back the saw away from cutting edge a few
inches, pull the trigger and re-enter the cut slowly.
5. If the saw binds and stalls, maintain a firm grip
and release the trigger immediately. Hold the saw
motionless in the workpiece until the blade comes
to a complete stop.
6. After finishing a cut, be sure the lower guard closes
and the blade comes to a complete stop before
setting the saw down.
Electric Brake
Select models feature an electrIc brake. The brake
engages when the trigger is released, causing the
blade to stop and allowing you to proceed with your
work. Generally, the saw blade stops within two sec-
onds. However, there may be a delay between the time
you release the trigger and when the brake engages.
Occasionally the brake may miss completely. If the
brake misses frequently, the saw needs servicing by
an authorized MILWAUKEE service facility. The brake
is not a substitute for the guard, and you must always
wait for the blade to stop completely before removing
the saw from the workpiece. The correct brush grade
must be used for proper operation of the brake. Use
only the correct MILWAUKEE replacement brushes
when servicing the tool.
Troubleshooting
If the blade does not follow a straight line:
• Teeth are dull. This is caused by hitting a hard object
such as a nail or stone, dulling teeth on one side. The
blade tends to cut to the side with the sharpest teeth.
• Shoe is out of line or bent
• Blade is bent
• Rip fence or guide is not being used
If the blade binds, smokes or turns blue from friction:
• Blade is dull
• Blade is on backwards
• Blade is bent
• Blade is dirty
• Workpiece is not properly supported
• Incorrect blade is being used
APPLICATIONS
To reduce the risk of injury, always
WARNING
unplug tool before attaching or
removing accessories or making adjustments.
Use only specifically recommended accessories.
Others may be hazardous.
Always wear proper eye protection marked to
comply with ANSI Z87.1.
Selecting Tilt-Lok™ Handle Positions
The Tilt-Lok™ handle is a feature which allows the
user to adjust the angle of the handle for optimum
cutting positions. The Tilt-Lok™ handle has eight (8)
detents which allow the handle to snap into position .
See "Adjusting Tilt-Lok™ Handle" for instuctions on
adjusting the handle. Refer to the chart for suggested
handle positions.
