General Information
Carbon monoxide (CO) has the distinction of being one of the few commonly encountered industrial gasses that is
both highly toxic (poison) and odorless. When inhaled, CO acts as a chemical asphyxiant by preferentially combin-
ing with hemoglobin in the blood stream. As a result, the hemoglobin is not able to transport its normal amount of
oxygen, which results in under-oxygenation of tissues. Symptoms of low-level CO exposure include headaches,
dizziness, confusion, and nausea. However, loss of consciousness, permanent injury and death may result
from continued or more intense exposure. Because of the health hazards associated with CO inhalation, the Oc-
cupational Safety and Health Administration (OSHA) have imposed personal exposure limits. The OSHA exposure
limits, which are specied in the 29 CFR 1910.1000 (1998 Revision), allow for a 200 PPM Ceiling Limit and a TWA
of 35 PPM per 8-hour shift/40-hr workweek. It is strongly recommended that the OSHA 29 CFR 1910.1000 (Code
of Federal Regulations) be consulted for more information on exposure limits for various hazardous materials. If CO
Poisoning is suspected immediately remove the victim to fresh air and obtain emergency medical attention.
Proper Ventilation:
THIS SAW IS SHIPPED FROM THE FACTORY WITHOUT A CATALYTIC CONVERTER. It is important to be aware
that saws with catalytic converters reduce CO and hydrocarbon (HC) emissions. The exhaust still contains CO. If the
workspace is too conned or under-ventilated, CO may accumulate until it eventually exceeds OSHA limits. When
this happens, action must be taken to remove workers from areas of high concentration. Operators and work area
supervisors should take precautions to insure adequate ventilation of the workspace at all times. Carbon monoxide
detection monitors should be used to determine that adequate ventilation exists.
WARNING
POISON EXHAUST GAS
THIS SAW IS SHIPPED FROM THE FACTORY WITHOUT A CATALYTIC CONVERTER.
THE ENGINE PRODUCES CARBON MONOXIDE EXHAUST EMISSIONS AND IS NOT SAFE FOR USE IN
ENCLOSED AREAS. USE OF A CATALYTIC CONVERTER REDUCES THE CARBON MONOXIDE EXHAUST
EMISSIONS, BUT STILL IS NOT SAFE FOR USE IN ENCLOSED AREAS.
USE ONLY IN WELL-VENTILATED AREAS. WORK SITE AIR QUALITY MUST COMPLY WITH
OSHA 29 CFR 1910.1000 PER TABLE Z-1, LIMITS FOR AIR CONTAMINANTS.
MONITOR WORKSPACE AIR QUALITY TO INSURE COMPLIANCE. FAILURE TO COMPLY WILL RESULT IN
DANGER TO LIFE AND CAUSE PERMANENT INJURY OR DEATH.
WARNING
HEARING HAZARD
DURING NORMAL USE OF THIS MACHINE, OPERATOR MAY BE EXPOSED TO A NOISE
LEVEL EQUAL TO 85 dB (A) OR GREATER. TEMPORARY AND/OR PERMANENT DAMAGE TO HEARING
MAY RESULT. HEARING PROTECTION REQUIRED.
