▪ Important Safety Instructions
charger incorrectly or misusing it may damage the charger or create hazardous conditions for the user.
• 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 specied 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.
• 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 Returns policy in the
back of this guide.
- 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
affect 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.
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.

1) Illuminates red when power cord is plugged in and
power switch on back of unit is turned on.
2) Illuminates orange or red when in charge mode and
changes to green when battery charging is in the nal stage*. During this stage
a 1 hour minimum in this stage is required, however 24 hours is recommended
for 100% charge. If the Charging LED Indicator remains orange or red after a 10
hour period switch the charger OFF and remove the battery connections. Insure
the battery polarity is correct, and if so, replace the battery.
3) (on back) Power is ON when switched to “I” and OFF when
switched to “O”
4) Fuse holder: Contains a 10A fuse in case of overload.

The HF Charger Series has been designed to provide fully automatic recharging of most 12V, 14V or 16V maintenance
free, deep-cycle, AGM and gel-cell batteries. If possible, disconnect all loads from the battery by removing battery cables,
opening a disconnect switch, or switching loads off.
To charge your 12V, 14V or 16V battery:
2) Connect the red positive (+) clip of the charger cables to the positive (+) terminal of the vehicle battery.
