It is important that you read the entire manual to become familiar with the unit BEFORE you begin assembly.  \nTechnical Specifications  \nInput Voltage: 115V  \nOutput Voltage: 13.5V  \nCharging Current: 1.1 Amps  \nBattery Cables: 6 Foot long  \nOverall Dimensions: 3-1/2”W X 6-5/8” L X 7” H  \nPower Cord: 18 Gauge X 2 Wire UL® listed  \nNet Weight: 2.5 Lbs.  \nAutomatic charging: Battery Charger will not overcharge.  \nMultiple LED indicator lights: Red LED (on left) = reversed polarity,  \nRed LED (center) = “charging” mode,  \nGreen LED (on right) = fully charged – trickle charge mode.  \nFor best results, the capacity of the battery should be below 24 Ah.  \nSafety Warnings and Precautions  \nWARNING: When using product, basic safety precautions should always be followed to reduce the risk of personal injury and damage to equipment.  \nRead all instructions before using this product!  \nWORK AREA  \n1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.  \n2. do not operate the Battery Charger in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Electrical products create sparks which may ignite the dust or fumes.  \n3. Keep bystanders, children, and visitors away while operating the Battery Charger. Distractions can cause you to lose control. Protect others in the work area from sparks. Provide barriers or shields as needed.  \nELECTRICAL SAFETY  \n4. Grounded products must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. do not use any adapter plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If agrounded product should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.  \nSKU 93781 For technical questions please call 1-800-444-3353. Page 2  \n5. double insulated products are equipped with a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. do not change the plug in any way. Double insulation  eliminates the need for the three wire grounded power cord and grounded power supply system.  \n6. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is grounded.  \n7. do not abuse the Power Cord. Never use the Power Cord to carry the Battery Charger or pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp edges, or moving parts. Replace damaged Power Cords immediately. Damaged Power Cords increase the risk of electric shock.  \n8. When operating a power tool outside, use an outdoor extension cord marked“W-A”or “W”. These extension cords are rated for outdoor use, and ","cbCaieDxXI7hkBLE","https://ap.wps.com/l/cbCaieDxXI7hkBLE","pdf",640560,12,"English","# Technical Specifications\n# Safety Warnings and Precautions\n## Work Area\n## Electrical Safety\n## Personal Safety\n## Tool Use and Care\n## Service","[{\"question\":\"What do the LED indicators show on the 93781 charger?\",\"answer\":\"The left red LED indicates reversed polarity.
