2. Recharge only with the charger specied by
the manufacturer. A charger that is suitable for
one type of battery pack may create a risk of
re when used with another battery pack.
3. Use power tools only with specically desig-
nated battery packs. Use of any other battery
packs may create a risk of injury and re.
4. 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 termi-
nals together may cause burns or a re.
5.

for operation. Check the security of the cutting
tool and the guard and the switch trigger/lever
for easy and proper action. Check for clean
and dry handles and test the on/off function of
the switch.
3. Check damaged parts before further use of
the tool. A guard or other part that is damaged
should be carefully checked to determine
that it will operate properly and perform its
intended function. Check for alignment of
moving parts, binding of moving parts, break-
age of parts, mounting, and any other condi-
tion that may affect its operation. A guard or
other part that is damaged should be properly
repaired or replaced by our authorized ser-
vice center unless indicated elsewhere in this
manual.
