Problem:

This product contains an internal Nickel-Metal Hydride battery pack 

and  must be recharged every 30-45 days to ensure optimum 

performance. If product is stored for long periods of time and not 

charged regularly the batteries may become permanently damaged.

Batteries do not hold a 

charge, LED lights are very 

dim or do not emit any light 

at all.

The Charging Indicator LED displays an estimate of battery condition 

during charging, and is not a precise measurement of battery capacity. 

If you are experiencing any of the problems listed, it may be due to 

an overly sensitive charging indicator. The unit may still charge and 

operate normally. Try charging the unit for 6 hours, disregarding the 

behavior of the charging indicator LED. Remove from charge after 6 

hours and use normally. If you are satisfied with the performance 

continue using 6 hour charging cycles for your worklight.

Charging Indicator LED 

does not change from red 

to green, flashes from red 

to green during charging, or 

glows green too quickly.

Be sure the charging cord is completely seated into the charging jack 

on the worklight and that the AC adapter is completely seated into a 

110-120 VAC wall outlet. If the wall outlet is controlled by a wall switch 

be sure it is turned on. If you are using the DC adapter check your 

automobile manual for proper DC outlet operation. 

Charging indicator LED 

does not light up at all.

Storage

Charge unit after each significant use and before any long period of storage. Do not store worklight 

for long periods with the battery in uncharged condition. This could permanently damage the 

battery. Store worklight and charging adapters in a clean, dry area. Be sure to keep charging adapters 

included with this product stored separately from similar items belonging to other products. Only the 

charging adapters included with this worklight are compatible. Mistakenly using a non-compatible charger 

could cause damage to worklight or personal injury. The worklight can also be stored in vehicle for 

roadside emergency situations. If stored in vehicle, recharge battery every 30-45 days to ensure top 

performance in an emergency. To prevent worklight from being damaged, properly secure worklight and 

any accessories in a safe place in vehicle.

Cleaning

All exterior surfaces of worklight can be wiped clean with a soft cloth dampened with a soap and water 

solution. Do not immerse or submerge any part of worklight in water or other solvent. Use only a gentle 

soap detergent in cleaning solution. Never use solvents or cleaning agents containing petroleum (gasoline, 

kerosene, oil), paint thinner, turpentine, alcohol, or ammonia. Harsh materials will damage surfaces.

Repair

Any repairs should be performed by qualified personnel only . Do not open exterior casing of worklight. 

There are no user serviceable parts inside. Opening or visible attempts to open or repair worklight may 

void warranties and/or cause damage to tool or personal injury. LED bulbs will never wear out under 

normal conditions and do not need to be replaced. Rechargeable battery pack cannot be replaced. 

This product contains an internal Nickel-Metal Hydride battery pack formulated from environmentally 

sensitive materials. This product must be disposed of properly. Contact a local recycler of batteries 

to handle disposal. Be aware that in many areas it is illegal to dispose of batteries improperly and 

doing so may result in fines and/or imprisonment. Consult local regulations for disposal. Never 

incinerate batteries as they may leak or explode.

Maintenance

The worklight features a stand-up base with a 

built-in magnet. Soft coating on bottom of base 

allows worklight to be magnetically attached 

to vehicle body panels or under hood without 

damaging or scratching paint. (Fig.4)

Magnetic Base

Do not set worklight on or near computer equipment, computer disks or other 

types of magnetic storage or equipment. Magnetic fields can erase data.
