create a risk of injury and fire.
3. 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 fire.
4. under abusive conditions, liquid may be
ejected from the battery; avoid contact.
if contact accidentally occurs,
flush with water. if liquid contacts eyes,
additionally seek medical help.
Liquid ejected from the battery
may cause irritation or burns.
Service
Have your power tool serviced by a qualified repair person using only identical
replacement parts. This will ensure that the safety of the power tool is maintained.
Heat Gun Safety Warnings
1. Hidden areas behind walls, ceilings,
floors, soffit boards, and other panels
may contain flammable materials that
could be ignited by the heat gun when
working in these locations. The ignition of
these materials may not be readily apparent
and could result in property damage and
injury to persons. When working in these
locations, keep the heat gun moving in a
back-and-forth motion.
Lingering or pausing in one spot could
ignite the panel or the material behind it.
2. Extreme care should be taken when
stripping paint. The peelings, residue and
vapors of paint may contain lead, which
is poisonous. Any pre-1977 paint may
contain lead and paint applied to homes
prior to 1950 is likely to contain lead. Once
deposited on surfaces, hand-to-mouth
contact can result in the ingestion of lead.
Exposure to even low levels of lead can
cause irreversible brain and nervous system
damage; young and unborn children are
particularly vulnerable. Before beginning any
paint removal process you should determine
whether the paint you are removing contains
lead. This can be done by your local health
department or by a professional who uses
a paint analyzer to check the lead content
of the paint to be removed. LEAD BASED
PAINT SHOULD ONLY BE REMOVED BY
A PROFESSIONAL AND SHOULD NOT
BE REMOVED USING A HEAT GUN.
3. Exercise CAUTION when using this
product outdoors. To reduce the risk
of electric shock, keep extension cord
connection dry and off the ground.
4. Persons removing paint should
follow these guidelines:
a. Move the work piece outdoors.
If this is not possible, keep the work
area well ventilated. Open the
windows and put an exhaust fan in one
of them. Be sure the fan is moving
the air from inside to outside.
b. Remove or cover any carpets,
rugs, furniture, clothing, cooking
utensils and air ducts.
c. Place drop cloths in the work area
to catch any paint chips or peelings.
Wear protective clothing such as extra
work shirts, overalls and hats.
