Summary

Important Safety Instructions

Risk of Explosive Gases

Working near lead-acid batteries is dangerous due to explosive gases. Follow safety instructions.

Injury Risk from Battery Types

Charge only rechargeable lead-acid batteries. Other types may burst, causing injury or damage.

Cord Placement and Protection

Position AC/DC leads to avoid tripping and damage from vehicle parts; protect from heat, oil, edges.

Personal Precautions

Working Alone Warning

Always have someone within range of your voice when working around lead-acid batteries.

Protective Gear and Safety

Wear eye protection, clothing protection, and rubber-soled shoes. Use damp cloth and rubber boots if needed.

Fire, Spark, and Tool Safety

Avoid smoking, sparks, flames, and dropping metal tools near batteries or engines.

Preparing to Charge Battery

Battery Removal Procedure

If removing battery, always remove the grounded terminal first. Turn off vehicle accessories.

Battery Terminal Cleaning

Clean battery terminals carefully, avoiding contact of corrosion with eyes.

Electrolyte Level Check

Add distilled water to reach the manufacturer-specified electrolyte level. Do not overfill.

Battery Voltage Determination

Determine battery voltage from owner's manual and set charger's voltage selector switch accordingly.

AC Power Cord Connection Instructions

Grounding Requirements

Charger must be grounded to reduce shock risk. Plug into a properly installed and grounded outlet.

Using Adapters Safely

Use temporary adapters only if needed, ensuring the outlet plate screw is properly grounded.

Extension Cord Guidelines

Use extension cords only if necessary, ensuring correct pin configuration, wiring, and wire size.

Charger Location

Optimal Placement

Locate the charger as far away from the battery as charger cables permit.

Ventilation and Corrosion Prevention

Ensure ventilation and prevent battery gases/electrolyte from contacting the charger.

Safe Operating Environment

Operate the charger only in a well-ventilated area, free of dangerous vapors.

Storage Conditions

Store the charger in a safe, dry location and maintain it in perfect condition.

DC Connection Precautions

Switch and Clamp Safety

Set switches to OFF (O) and disconnect AC cord before connecting/disconnecting clamps. Never let clamps touch.

Clamp Connection Quality

Ensure best mechanical and electrical connection for clamps to prevent slipping and sparking.

Battery in Vehicle or Connection to Engine

Vehicle Load and Electrical System

Turn off all vehicle loads and correct any electrical system defects causing low battery.

Battery Polarity Check

Check battery post polarity. POSITIVE posts usually have a larger diameter than NEGATIVE posts.

Negative-Grounded Vehicle Connection

Connect POSITIVE clamp to battery, NEGATIVE clamp to chassis away from battery.

Positive-Grounded Vehicle Connection

Connect NEGATIVE clamp to battery, POSITIVE clamp to chassis away from battery.

Battery Outside Vehicle Charging

Polarity and Cable Connection

Check polarity, attach cable to negative post, connect positive clamp to positive post.

Final Connection and Disconnection Safety

Position away from battery for final connection and follow reverse sequence for disconnection.

Charger Features and Controls

ON/OFF Switch

The ON/OFF switch disconnects AC input current but not the output from the battery.

Ammeter

Indicates amps flowing from charger into battery, with zones marked CHARGE, START.

Rate/Voltage Selector Switch

Controls voltage and current. Ensure selected voltage matches battery. Select amp rate for application.

Engine Start Function

Provides high current for starting vehicles with depleted batteries. Charge for 5 mins before starting.

Overload Protection

Uses output circuit breaker and thermal breaker to prevent overheating and damage.

Electrical Condition of Battery

Checking Refillable-Top Batteries

Use a hydrometer to check specific gravity of electrolyte to determine state of charge.

Checking Sealed-Top Batteries

Use a high resolution voltage tester to check the state of charge of sealed-top batteries.

Battery Temperature Effects

Battery temperature significantly affects efficiency and power requirements for starting engines.

Battery Charging

Charging Procedure Overview

Determine battery state of charge and connect charger as per instructions in sections 7 and/or 8.

Charging Time Chart

Chart provides approximate recharge time based on battery type, voltage, state of charge, and charging rate.

Alternative Recharge Time Calculation

Formula provided for calculating recharge time based on reserve capacity, needed charge, and charger rate.

Multiple Battery Charging

Parallel Charging

Batteries can be connected in parallel for maintenance charging. Charge time and rate adjust proportionally.

Assembly Instructions

Handle Attachment

Attach the handle to the unit with the provided screws.

Rubber Feet Installation

Remove backing and attach the four rubber feet on the bottom of the unit.

Maintenance Instructions

Clamp Cleaning

Clean charger clamps each time after use to prevent corrosion from battery fluid.

Cord Storage

Coil cords when the charger is not being used to prevent damage.

Professional Servicing

Other servicing should be performed only by qualified service personnel.

Troubleshooting

No Meter Reading

Check AC outlet, battery connections, circuit breaker, and ensure all operating instructions were followed.

High Meter Readings

Ensure battery connections are not reversed. High readings may also indicate dead cells or battery issues.

Limited Warranty

Warranty Terms

Warrants against defective material or workmanship. Repair/replacement at manufacturer's option. Void if misused.

Exclusions and Limitations

Excludes implied warranties and consequential damages. State laws may provide additional rights.

Customer Service
