9DANGERE X P L O S I O N / F I R EHAZARDRead ALL safetyinstructions before usingor handling the fuel cell.Failure to follow ALLinstructions may result inexplosion or fire. This maycause severe personalinjuries or propertydamage.Keep the fuel cell awayfrom heat, sparks andopen flame.Exposure to temperaturesabove 120°F (49°C) maycause the fuel cell to burst,releasing flammable gas.WARNINGSunlight can raise the inside temperature of anunventilated car or van to above 140°F (60°C).Do not puncture or attempt to open the fuel cell; it isnon-refillable.Do not incinerate, reclaim or recycle the fuel cell.Do not smoke while installing or operating the meteringvalve.Do not inhale the spray.Keep out of the reach of children.Store fuel cell(s) in well-ventilated areas only.NOTE1. Do not attempt to reuse the metering valve!Replace with fresh fuel cell/valve, and dispose ofspent cell/valve properly.2. When replacing fuel cell also clean or replace theair filter for optimum tool operation.Fuel Cell There is a second container inside the fuel cell. The innercontainer holds the fuel. The space between the innercontainer and the outer cylinder is filled with a gas, called thepropellant, which is under pressure.To eject the fuel, propellant pressure squeezes the innerfuel container, much as you squeeze a tube of toothpaste.This squeezing action ensures that all the fuel is used, andthat the Paslode Finish nailer can operate in any position.Because of this container-within-a-container design, youmight hear the sound of fluid when shaking the fuel cell afterall the fuel has been used. This is the propellant, whichremains between the containers even after all the fuel hasbeen expelled.If you expose the empty fuel cell to extreme temperatures,the propellant gas will expand and could cause the containerto burst, releasing flammable gases.Metering ValveThe metering valve contains a fuel metering system to injectthe correct amount of fuel into the combustion chamber.The metering valve with the yellow face is the only valvethat will operate properly with the Paslode Angled FinishNailer.Fuel Cell and Metering ValveImpulse tools are powered by an internal combustionengine and are effected by altitude. The tool maylose power or become erratic at elevations of 4000feet or greater.When using the tool at elevations of4000 - 9000 ft. it is recommended that the highaltitude fuel metering valve (#219247) be used.NOTE: Altitude Restriction
