ALWAYS use a battery lifting strap when lifting a battery. It is the most convenient
method and assures that the battery acid will not spill. It also helps to prolong the
life of the battery.
DO NOT tip the batteries. Keep the batteries in an upright position.
NEVER allow any of your tools and/or battery cable(s) to contact BOTH battery
post(s) at the same time. An electrical short may occur and serious personal injury
or damage may occur.
When tightening the clamps, always use a box wrench. Pliers will “round off” the
nuts. NEVER wiggle the battery terminal(s)/post(s) when tightening. The battery
may become damaged.
The POSITIVE (+) RED battery cable MUST connect to the POSITIVE (+) battery
terminal(s)/post(s), otherwise serious damage will occur to the electrical system.
Install protective caps on POSITIVE (+) and NEGATIVE (-) battery terminals.
