1.Before you use your battery charger, be sure to read all instructions and cautions printed on:

Battery Charger

Battery

Vehicle or unit using battery

2.Use battery charger on LEAD ACID type rechargeable batteries only, such as used in autos, trucks, tractors, airplanes, vans, RV's, trolling motors, etc. Charger is not intended to supply power to low-voltage electrical system other than in an automotive application.

WARNING: Do not use battery charger for charging dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause injury to persons and damage to property.

3.Use only attachments recommended or sold by manufacturer. Use of non-recommended attachments may result in fire, electric shock, or injury.

4.When disconnecting the battery charger, pull by the plug not by the cord. Pulling on the cord may cause damage to cord or plug.

5.Locate battery power cord so it cannot be stepped on, tripped over, or subjected to damage or stress.

6.Do not operate charger with damaged cord or plug. Have cord replaced immediately.

7.Do not operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any way. Take it to a qualified professional for inspection and repair.

8.Do not disassemble charger. Take it to a qualified professional when service or repair is required. Incorrect reassembly may result in electric shock or fire.

9.To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or cleaning.

10.Do not use an extension cord unless absolutely necessary. Use of an improper extension cord could result in fire or electric shock. If an extension cord must be used, make sure that:

Pins on plug of extension cord are the same number, size, and shape as those of plug on charger.

Extension cord is properly wired and in good electrical condition.

Wire size is large enough for AC ampere rating of charger, as specified below:

Length of cord (feet):

25

50

100

11.Always charge battery in a well ventilated area.

NEVER operate in a closed-in or restricted area without adequate ventilation.

WARNING: Risk of explosive gas.

12.Locate charger as far away from battery as DC charger cables permit.

13.Do not expose charger to rain or snow.

14.NEVER charge a frozen battery. If battery fluid (electrolyte) is frozen, bring into a warm area to thaw before charging.

15.NEVER allow battery acid to drip on charger when reading specific gravity or filling battery.

16.NEVER set a battery on top of charger.

17.NEVER place charger directly above battery being charged. Gases from battery will corrode and damage charger.

18.NEVER touch the battery clips together when the charger is energized.
