Maintenance - Black & Decker 2683-220 Instruction Manual

154577/2683-220 IC 5/17/02
The saw should be brought up to full operating speed before starting a cut
or restarting a cut after the unit has been stopped with the blade in the kerf.
Failure to do so can cause stalling and kickback.
Any other conditions which could result in pinching, binding, twisting, or
misalignment of the blade could cause kickback. Refer to the sections on
"Adjustments and Set-Up" and "Operation" for procedures and techniques
that will minimize the occurrence of kickback.

MAINTENANCE

Cleaning
Use only mild soap and a damp cloth to clean the tool. Many household
cleaners contain chemicals which could seriously damage plastic. Also, do
not use gasoline, turpentine, lacquer or paint thinner, dry cleaning fluids or
similar products. Never let any liquid get inside the tool; never immerse any
part of the tool into a liquid.
Lubrication
Self lubricating ball and roller bearings are used in the tool and relubrication is
not required. However, it is recommended that, once a year, you take or send
the tool to a B&D authorized service center for a thorough cleaning,
inspection, and lubrication of the gear case.
Brushes
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY BEFORE
SERVICING.
Inspect carbon brushes regularly by unplugging tool, removing the brush
inspection cap (Figure 2) and withdrawing the brush assembly. Keep brushes

clean and sliding freely in their guides. Always replace a used brush in the
same orientation in the holder as it was prior to removal. Carbon brushes have
varying symbols stamped into their sides, and if the brush is worn down to the
line closest to the spring, they must be replaced. Use only identical B&D
brushes. Use of the correct grade of brush is essential for proper operation of
electric brakes on units so equipped. New brush assemblies are available at
B&D service centers. The tool should be allowed to "run in" (run at no load
without a blade) for 10 minutes before use to seat new brushes. This is
especially important for saws equipped with electric brakes which may be
erratic in operation until the brushes are properly seated (worn in). While
"running in" DO NOT TIE, TAPE, OR OTHERWISE LOCK THE TRIGGER
SWITCH ON. HOLD SWITCH BY HAND ONLY.
IMPORTANT!
To assure product SAFETY and RELIABILITY, particularly for double insulated
tools, repairs, maintenance and adjustment (excluding maintenance
described in this manual) should be performed by B&D service centers or
authorized service centers, using identical B&D replacement parts.
Blades
A dull blade will cause slow, inefficient cutting overload on the saw motor,
excessive splintering, and could increase the possibility of kickback. It is a
good practice to keep extra blades on hand so that sharp blades are available
while the dull ones are being sharpened. (See "Saws-Sharpening" in the
yellow pages.) In fact, many lower priced blades can be replaced with new
ones at very little cost over the sharpening price.
Hardened gum on the blade will slow down the cutting. This gum can best be
removed with kerosene, turpentine, or oven cleaner. B&D manufactures a
complete line of saw blades and the following types of blades are available
from your dealer.
