WARNING
Battery terminals, battery cables, or metal tools
could short against metal components causing
sparks. Sparks can cause the battery damage
and high heat, resulting in personal injury.

not allow the battery terminals or battery cables
to touch any metal parts of the machine.
-- Do not allow metal tools to short between the
battery terminals or battery cables and metal
parts of the machine.

other than the battery cable or wire harness con-
nector that came with the product.
-- Always keep the battery retainers and covers in
place to protect and secure the batteries.
IMPORTANT: To prevent accidentally shorting a
disconnected battery cable across other compon-
ents or tools, insulate the battery cable terminal
with a 76 mm (3 inch) length of 1.27 mm (0.5 in) in-
