WARNING: Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities, contain chemicals known (to the State of California) to
cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are: lead from lead-based paints, crystalline silica from bricks and ce-
ment or other masonry products, arsenic and chromium from chemically treated
lumber. Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such as those dust masks that are
specially designed to filter out microscopic particles. (California Health & Safety
Code § 25249.5, et seq.)
22.
WARNING: We recommend that people with pacemakers not use this tool. This
tool produces strong electromagnetic fields that can cause interference or failure of
the pacemaker. People with pacemakers should consult their physician(s) for ad-
vice.

Replace the Chain Cover (46), and tighten the Nylon Insert Nut (67) so that the
Cover is snug, but not tight. (See Figure D, next page.)
Pull gently up on the tip of the Guide Bar (52), while turning the Blade Adjustment
Screw (61) clockwise (photo 005.) Because the saw is light in weight, this is easier
if someone holds the handle. Do not overtighten the Chain. There should only be
1
about / ” of space when the Chain is pulled upward at the center of the Guide Bar.

To Check For Proper Chain Tension:
1.
The Chain (57) tension is proper when the Chain snaps back after being pulled 1/4”
away from the Guide Bar (52) with light force. There should be no sagging between
the Chain and Guide Bar underneath. When necessary, use a screwdriver to turn
the Adjustment Screw (61) clockwise to tighten, or counterclockwise to loosen, the
Chain (57). (See Figure D.)
2.
NOTE: A Chain (57) which is too taut leads to premature Chain and Guide Bar (52)
wear. A Chain which is too loose may jump out of the Guide Bar groove and dam-
age the tool or cause personal injury. New chains typically lose tension initially
during use. When necessary, readjust the Chain tension by following the directions
in Step # 1 of this section.
To RefillThe Automatic Chain Lubrication System:
1.
The Chain Saw features an automatic Chain Lubrication System with a built-in Oil
Reservoir. Lubrication of the Chain (57) is carried out automatically while the Chain
Saw is running. The oil level should be checked before each use of the Chain Saw.
2.
To refill the Oil Reservoir, unscrew the Oil Fill Cap (11). Fill the Oil Reservoir with a
quality grade chain saw Chain Oil (SAE 30). When filling, avoid introducing dirt or
other foreign material into the Oil Reservoir. Then, retighten the Oil Fill Cap onto the
Oil Reservoir. (See Figure D.)

INSPECTION, MAINTENANCE, AND CLEANING
1.
2.
WARNING: Always turn the On/OffTrigger (25b) to its “OFF” position and unplug the
Electric Cord (23) from its electrical outlet before performing any inspection, mainte-
nance, or cleaning. (See Figure E.)
BEFORE EACH USE, inspect the general condition of the Chain Saw. Check for
loose screws, misalignment or binding of moving parts, cracked or broken parts
(i.e., Chain, 57), damaged electrical wiring, and any other condition that may affect
its safe operation. If abnormal noise or vibration occurs, have the problem corrected
before further use. Do not use damaged equipment.
3.
4.
UPON EVERY THREE HOURS OF USE, make sure the Chain (57) is adequately
lubricated and taut. If necessary, remove the Guide Bar (52) and Chain. Clean the
groove in the Guide Bar thoroughly and clean the Oil Port in the Front Cover (42) to
ensure that it is not blocked or obstructed, see Figure B. To maximize the life of the
Guide Bar, turn the Guide Bar over and then reinstall. (See Figures C and D.)
PERIODICALLY, remove the Carbon Brush Housing (6) to inspect the condition of
the Carbon Brush (4). If the Carbon Brush is simply dirty, you may carefully clean it
with a pencil eraser. The Carbon Brush has a wear limit marking on it. You may
safely use the Carbon Brush up to the wear limit. When it has worn up to the wear
limit, the Carbon Brush must be replaced. When replacing the Carbon Brush make
sure it fits neatly into its Carbon Brush Holder (5) and that the spring on the Carbon
Brush operates freely. Make sure the carbon portion of the Carbon Brush contacts
the Motor Armature (24). After inspection or replacement, replace the Carbon Brush
Housing. (See Figure E.)
5.
6.
TO CLEAN: Clean with a soft brush, cloth, or vacuum to remove debris from the
Cold Saw. If necessary, use a mild detergent or mild solvent. Then, use a premium
quality, lightweight machine oil to lubricate all moving parts.
If cutting efficiency diminshes, the included round file may be used to sharpen the
teeth of the chain. The chain should also be sharpened professionally at least once
a year, depending on use.
