• Know the signs of CO and CO2 poisoning.
• Headaches, stinging eyes;
• Dizziness, disorientation;
• Diculty breathing, feels of being suocated.
• Proper ventilation air exchange (OSHA 29 CFR
1926.57) to support combustion and maintain
acceptable air quality shall be provided in ac-
cordance with OSHA 29 CFR Part 1926.154,
ANSI A10.10 Safety Requirements for Tempo-
rary and Portable Space Heating Devices and
Equipment used in the Construction Industry or
the Natural Gas and Propane Installation Codes
CSA B149.1.
• Periodically monitor levels of CO, CO2, and
NO2 existing at the construction site – at the
minimum at the start of the shift and after 4
hours.
• Provide ventilation air exchange, either natural
or mechanical, as required to maintain accept
able indoor air quality.

• Ensure that the ow of combustion and ventila-
tion air exchange cannot become obstructed.
• As the building "tightens up" during the con-
struction phases ventilation may need to be
increased.
•Not for use with ductwork.
ELECTRICAL SAFETY
•Make sure your extension cord is in good con-
dition. When using an extension cord, be sure
to use one heavy enough to carry the current
your product will draw. If in doubt, use the next
heavier gauge. The smaller the gauge number,
the heavier the cord. An undersized cord will cause
a drop in line voltage resulting in loss of power and
overheating.
•To reduce the risk of personal injury and electric
shock, the product should not be played with or
placed where small children can reach it.
•To reduce the risk of electric shock, do not ex-
pose to water or rain.
•Never attempt to power the device with a battery
pack and extension cord at the same time.
• When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal
to another. Shorting the battery terminals together
may cause burns or a re.
• Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact ac-
cidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
• Do not use a battery pack or tool that is dam-
aged or modied. Damaged or modied batteries
may exhibit unpredictable behavior resulting in re,
explosion or risk of injury.
• Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or tem-
perature above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging
improperly or at temperatures outside the specied
range may damage the battery and increase the risk
of re.
SERVICE
• Have your power tool serviced annually by a
qualified repair person using only identical
replacement parts. This will ensure that the safety
of the power tool is maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
CARBON MONOXIDE
•
WARNING
Propane heater exhaust contains
high levels of carbon monoxide
(CO), a poisonous gas you cannot see or smell.
If you can smell the propane heater exhaust, you
are breathing CO. But even if you cannot smell the
exhaust, you could be breathing CO.
• The heater is only intended for use in the tem-
porary heating of a building or structure under
construction, alteration, or repair.
• Never use a propane heater inside homes,
garages, crawlspaces, recreational vehicles,
or other partly enclosed areas. Deadly levels of
carbon monoxide can build up in these areas.
• Even when you use a propane heater correctly,
CO may leak into the home. ALWAYS use a
battery-powered or battery-backup CO alarm in
the home.
• If you start to feel sick, dizzy, weak, or experience
a headache after the propane heater has been
running, move to fresh air RIGHT AWAY. See a
doctor. You could have carbon monoxide poisoning.
• Do not sleep while propane heater is operating.
• Not for home or recreation vehicle use.
•
WARNING
Air Quality Hazard:
• Do not use this heater for heating human living
quarters.
• Use of direct-red heaters in the construction
environment can result in exposure to levels of
CO, CO2, and NO2, considered to be hazardous
to health and potentially life threatening.
• Do not use in unventilated areas.
