▪ Important Safety Instructions
The HF Charger series generates a low DC voltage and high DC current to the battery being charged. Operating the
charger incorrectly or misusing it may damage the charger or create hazardous conditions for the user.
WARNING: EXPLOSION HAZARD
• The HF Charger series is designed to charge 12V, 14V and 16V lead-acid batteries of all types. Do not attempt to use with
batteries with voltages not matching the chargers specied voltage.
• Do not use this product where there are ammable fumes or gases.
• Do not use this product in an enclosure containing lead-acid batteries. These batteries vent explosive hydrogen gas, which
can be ignited by sparks from electrical connections.
• Never attempt to charge a frozen battery.
• Do not connect DC clamps to the carburetor, fuel lines, or sheet metal body parts.
WARNING: SHOCK HAZARD. KEEP AWAY FROM CHILDREN.
• Do not expose charger to water or rain or temperatures over 104 °F (40 °C).
• Do not open the charger. There are no user serviceable parts inside the unit. For service see the Warranty Policy in the
back of this guide.
WARNING: HEATED SURFACE - Ensure at least 2" (5 cm) air space is maintained on all sides of the charger.
• An extension cord should not be used unless absolutely necessary. Use of an undersized extension cord will adversely
a󰀨ect the output of the product and could prove to be dangerous. If an extension cord must be used, make sure that pins on
the plug of the extension cord are the same number, size and shape as those of the plug on the charger. We recommend
a minimum of a 16AWG cord for lengths up to 50’ and a minimum of a 14AWG cord for lengths up to 100’. We do not
recommend cords over 100’. Do not use this product with an ungrounded extension cord.
• Be sure AC and DC cords are not pinched or otherwise damaged by hoods, doors, or other moving engine components.
• Observe battery polarity.
*IMPORTANT* If this charger is to be used with a portable generator, it should be equipped with automatic voltage regulation
to ensure consistent output of the product.
