f. The chain saw should never be used to cut above the operator's shoulder height.
g. The operator should shut off the saw when carrying it over slippery surfaces, through
heavy brush, and when adjacent to personnel. The saw may be carried running (idle speed) for
short distances of less than 15 meters (50 feet) as long as it is carried to prevent contact with the
chain or muffler.
h. Never operate a chain saw when physically tired or under the influence of alcohol,
medication, or other drugs.

anything.
7.13.6.2 Chain Saws. Chain saws should be kept clean and sharp at all times, and kept in
sound mechanical condition with all guards, spark arresters, mufflers, handles, and other items
properly installed and adjusted. Observe these equipment precautions
a. Fuel for chain saws should be stored in approved vented containers that are marked to
show their contents. Never store the fuel near flammable materials. Keep the containers clean.
Always wipe the spout clean before filling the chain-saw tank. Filtering the fuel mixture will
ensure continued smooth engine operation.
b. Make sure that a proper mixture of fuel (gasoline and oil) is used. Check the fuel tank
and chain oiling reservoir for proper levels before use. The filler caps for the fuel tank and chain
oiling reservoir should be clearly marked and securely attached during operation and storage.
c. The chain saw should not be started within 3 meters (10 feet) of a fuel container.
d. The chain saw should not be fueled while running, hot, or near an open flame.
7.13.6.3 Right-of-Way Brush Removal. Brush clearance should be performed as part of
electrical maintenance work only to clear right-of-ways. Wear personal protective equipment as
covered for power trimming equipment. Recognize the hazards from poor work practices to
workers and to the environment and observe the following rules.
a. Cutters felling heavy brush or small trees should give sufficient warning to other
personnel. Never work so close that one worker could injure another with a swinging ax or hook.
b. Brush chippers should be operated only if authorized and by standing to the side of the
chipper chute while feeding the butt end of brush into the chipper first. Use the automatic shut-
off/stop control at the operator's station in an emergency.
