Maintenance and Servicing

Procedures not specifically explained
in this manual must be performed
only by a qualified technician.
TO PREVENT SERIOUS INJURY FROM
ACCIDENTAL OPERATION:
Turn the Power Switch of the tool off and unplug the
tool from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures.
TO PREVENT SERIOUS INJURY
FROM TOOL FAILURE:
Do not use damaged equipment. If abnormal
noise or vibration occurs, have the
problem corrected before further use.
Cleaning, Maintenance,
and Lubrication
1. BEFORE EACH USE, inspect the general condition
of the tool. Check for loose hardware, misalignment
or binding of moving parts, cracked or broken
parts, damaged electrical wiring, and any other
condition that may affect its safe operation.
2. Daily: The Saw Blade must be sharp and clean
to perform properly. Depending on materials cut
and frequency of tool use, the Saw Blade may
become clogged with metal particles and dull.
Dull Saw Blades rub the workpiece rather than
cut, which results in increased friction, higher
temperatures, and a burned workpiece. As often
as possible, check the condition of the Saw Blade
and, if necessary, replace a worn Saw Blade with
a new, 7-1/4" diameter, metal cutting Saw Blade
rated at 5,800 RPM or above. See "To Install A
Saw Blade" section for further information.
3. With a vacuum or compressed air, remove all metal
debris from the metal debris compartment of the
Saw. To do so, lift up and open the Main Lock Plate
to expose the metal debris compartment. Once
cleaned, close and lower the Main Lock Plate. Do
not immerse the Saw in liquid. See Figure I, below.

For technical questions, please call 1-800-444-3353.
4. Periodically: The Saw features two Carbon Brushes
which, periodically, should be examined for wear.
The Carbon Brushes are located on each side of the
Motor Housing. To inspect or replace the Carbon
Brushes, use a small standard screwdriver to remove
the Brush Covers. Then, carefully pull out the
Carbon Brushes. Examine the concave surface of
the Carbon Brushes.
If the Carbon Brushes appear to be in good condition,
but only dirty, they can be cleaned by rubbing with
a pencil eraser. If there are large scratches on the
Carbon Brushes, replace both Carbon Brushes
immediately with approved replacement Carbon
Brushes from Harbor Freight Tools. To reinstall the
Carbon Brushes, insert them into the two Brush
Holders. Turn the Carbon Brushes vertically so they
will fit properly into the Brush Holders. Then, replace
the Brush Covers. See Figure J, below.
