2.1 Electrical Warnings
• Servicing this equipment may require working with protective covers removed and utility power
connected. Use extreme caution during these procedures.
• Check that the power cord(s), plug(s), and outlets are in good condition.
• Danger of explosion if battery is incorrectly connected or replaced.
• Worn-out or damaged batteries are considered environmentally unsafe. Always recycle used
batteries or dispose of the batteries in accordance with all federal, state and local regulations.
• Do not open or mutilate batteries. Any gel or liquid emissions from the sealed lead-acid (SLA)
battery contain sulfuric acid, which is harmful to the skin and eyes. Emissions are electrically
conductive and corrosive.

• Batteries contain or emit chemicals known to the State of California to cause cancer and birth
defects or other reproductive harm. Battery post terminals and related accessories contain lead
and lead compounds. Wash hands after handling (California Proposition 65).
• Risk of Energy Hazard -12V max. / 7.2 (7) Ampere-Hour battery. Before replacing batteries,
remove conductive jewelry such as chains, wrist watches, and rings. High energy through
conductive materials could cause severe burns.
• Wear protective clothing and eye protection whenever installing, maintaining, servicing, or
replacing batteries.
• If any battery emission contacts the skin, immediately and thoroughly wash with water. Follow
approved chemical exposure procedures.
• Neutralize any spilled battery emission with the special solution contained in an approved spill kit
or with a solution of one pound Bicarbonate of soda to one gallon of water. Report chemical spills
and seek medical attention if necessary.
• Never use un-insulated tools or other conductive materials when installing, maintaining, servicing
or replacing batteries.
• A battery showing signs of cracking, leaking, or swelling should be replaced immediately with a
battery of identical type and rating.
