air temperature below +40°F (+4.5°C), or above +105°F
(+40.5°C). This is important and will prevent serious damage to
the battery pack.
2. The charger and battery pack may become warm to touch
while charging. This is a normal condition, and does not indi-
cate a problem. To facilitate the cooling of the battery pack after
use, avoid placing the charger or battery pack in a warm envi-
ronment such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other
appliance
b. Check to see if receptacle is connected to a light switch
which turns power off when you turn out the lights.
c. Move charger and battery pack to a location where the sur-
rounding air temperature is approximately 65°F - 75°F (18°-
24°C).
d. If charging problems persist, take the tool, battery pack and
charger to your local service center.
4. The battery pack should be recharged when it fails to produce
sufficient power on jobs which were easily done previously. DO
NOT CONTINUE to use under these conditions. Follow the
charging procedure. You may also charge a partially used pack
whenever you desire with no adverse affect on the battery pack.
5. Under certain conditions, with the charger plugged into the
power supply, the exposed charging contacts inside the charg-
er can be shorted by foreign material. Foreign materials of a
conductive nature such as, but not limited to, steel wool, alu-
minum foil, or any buildup of metallic particles should be kept
away from charger cavities. Always unplug the charger from the
power supply when there is no battery pack in the cavity.
Unplug charger before attempting to clean.
6. Do not freeze or immerse charger in water or any other liquid.
WARNING: Shock hazard. Don't allow any liquid to get inside
charger.

FAMILIARIZATION
Switch
The saw is controlled by a trigger switch (A)
and lock off button (B). The switch lock off
button must be pressed before the trigger
switch will turn the saw on. Releasing the trig-
ger turns the saw off.
NOTE: This tool has no provision to lock the
switch on. The saw should never be locked
on by any means.
Windows
The saw is equipped with a sight window on
the side of the guard and a front window on
the front of the guard. These windows allow
the user to see a cutting line on the material to be cut.
WARNING: Do not operate the saw with a damaged or miss-
ing sight or front window. If window is damaged or missing, have
the saw serviced at an authorized service center. If saw is operat-
ed without the window, metal chips could fly through the guard and
cause personal injury.
CAUTION: Do not use oil or cutting fluids with the metal
saw. Do not use cleaning fluids to clean front window.
Cleaning fluids, cutting fluids, or oils could harm the plastic in the
front window, interferring with the safe operation of the saw.
Saw Shoe
The front of the saw shoe has a kerf indicator (E) that allows the
operator to glide the saw along cutting lines. Aligning the cutting line
with the notch on the front of the shoe and centering it using the
