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.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 Cordless Finish nailer can operate in anyposition.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 TrimMaster 18 ™ FinishNailer.Fuel Cell and Metering ValveNOTE1. 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 the air filter foroptimum tool operation.NOTE: Altitude RestrictionImpulse technology is powered by an internalcombustion engine and are effected by altitude.The tool may lose power or not cycle consistentlyat elevations of 4000 feet or greater. When usingthe tool at elevations of 4000 feet it isrecommended to use the blue high altitude fuelmetering valve part #219247.
