EMERGENCY WORKLIGHTThe Worklight is controlled by a sliding On/Off switch located on the domed partof the light assembly. Make sure the lamp is turned OFF when the unit is beingrecharged or stored. The lamp is efficient and will operate up to 114 hours on afull charge. The lamp is designed to last the life of the product.6. AIR COMPRESSOR/TIRE INFLATORIMPORTANT: Read Instructions Carefully To Avoid Possible Injury Or PropertyDamage.The built-in 12 Volt DC air compressor is the ultimate compressor for all vehicles,trailer tires and recreational inflatables. Three different sized nozzles are sup-plied. Each nozzle will clip on the end of the standard tire valve connector locat-ed at the free end of the compressor hose. The compressor nozzles are storedinside the hose well. The compressor hose with tire fitting is stored in a retainingwell between the jumper cable channels on the rear of the unit. The compressorcan operate long enough to fill up to 3 average sized tires before the battery mustbe recharged.The compressor may be used by removing the air hose from the storage well andif required, fitting an appropriate nozzle to the air hose. An On/Off switch locat-ed on the rear of the unit controls the power to the compressor and the gaugelight. Refer to Figure 3 for locations of compressor hose, nozzle storage hatchand hose. Return hose to the storage compartment after use.6.1 Warnings for compressor useThe compressor is capable of inflating up to 260 pounds per square inch (psi)pressure. To avoid over-inflation, carefully follow instructions on articles to beinflated. Never exceed recommended pressures. Bursting articles can cause seri-ous injury. Always check pressure with the pressure gauge. Never leave com-pressor unattended while in use. Allow unit to cool after 10 minutes of continu-ous operation.93. After initial 24 hour charge, charge this device for at least 14-16 hours or untilthe green FULL indicator lights. Charge at least once a month when not in use.4. When charging is completed and the green FULL LED lights, remove theAC/DC charger plug and store in a safe place.NOTE: The unit cannot be overcharged using the AC method. The VECTOR®system also comes with a DC/DC charging adapter for recharging the unit froma 12 volt DC accessory socket in a vehicle or boat .This recharging method will NOT recharge the unit as effectively as rechargingfrom a 120 volt AC outlet. The 12 Volt DC recharging procedure is recommend-ed only when it is necessary, as continued use of the 12 Volt DC recharging pro-cedure may shorten the battery system’s life.If unit is fully discharged, it is recommended that the vehicle being used for rechargingbe left running while the unit is being charged via the 12 Volt DC method.WARNING:Do not recharge for more than 3-4 hours maximum using 12 Volt DC method3.2 12 Volt DC Charging1. Insert one end of the DC/DC charging adapter into a 12 Volt DC accessoryreceptacle on the vehicle or boat (figure B)2. Insert the plug at the other end of this charging adapter into the 12 Volt DCaccessory socket on the front of the unit.3. Charge the unit until the green FULL indicator lights when the battery statuslevel pushbutton is pressed. DO NOT EXCEED 3-4 HOURS MAXIMUM.4. When charging is completed, remove the charging cord and store in a safeplace.3.3 Estimated Battery LifeTable I shows the relationship of the frequency of use between recharging andthe expected number of discharge/recharge cycles.Table I - Estimated Battery Life between recharges (lifetime of unit’s battery)Use Recharges1 1000+5 700+10 500+4. OPERATION AS A 12 VOLT PORTABLE POWER SUPPLY1. Lift up the cover of the unit’s 12 Volt DC accessory receptacle (See Figure 1)2. Insert the 12 volt DC plug from the appliance into the receptacle on the unit.3. Switch on the appliance, and operate as usual.CAUTION:DO NOT USE THIS UNIT TO OPERATE APPLIANCES THAT DRAW MORETHAN 20 AMPS DC
