Your risk from these exposures varies, depending on how often you

do this type of work. To reduce your exposure to these chemicals:

work in a well ventilated area, and work with approved safety

equipment, such as those dust masks that are specially designed to

filter out microscopic particles.

AIR SUPPLY

Tools operate on a wide range of air pressures. It is recommended

that air pressure measures 90 psig at the tool with the trigger fully

depressedandnoloadappliedtothetool.Higherpressure(over

90 psig;6.2bar)raisesperformancebeyondtheratedcapacityofthe

tool,whichwillshortentoollifeandcouldcauseinjury.

Alwaysuseclean,dryair.Dust,corrosivefumesand/orwaterinthe

airlinewillcausedamagetothetool.Drainwaterfromairlines

andcompressorpriortorunningtool.Cleantheairinletfilterscreen

I.D.andfittingsshouldhavethesameinsidedimensionsandbe

tightly secured.

Ensure an accessible emergency shut off valve has been installed in

the air supply line and make others aware of its location.

LUBRICATION

Lubricatetheairmotordailywithhighqualityairtooloil.Ifnoairline

oilerisused,run1/2oz.ofoilthroughthetool.Theoilcanbesquirted

into the tool air inlet or into the hose at the nearest connection to the

air supply, then run the tool. A rust inhibitive oil is acceptable for air

tools.

WARNING:Afteranairtoolhasbeenlubricated,oilwilldischarge

throughtheexhaustportduringthefirstfewsecondsofoperation.The

exhaustportmustbecoveredwithatowelbeforeapplyingairpressure

topreventseriousinjury.

OPERATION

Always turn off the air supply, drain hose of air pressure and detach

toolfromairsupplybeforeinstalling,removingoradjustinganypart

or accessory on this tool, or before performing any maintenance on

this tool.

Speedadjustmentisachievedthroughvariablepressureon

Increasing the pressure will increase the speed of the blade.

ToChangeBlades:

1. Detachfromairsupply.

TROUBLESHOOTING

Otherfactorsoutsidethetoolmaycauselossofpowerorerratic

action.Reducedcompressoroutput,excessivedrainontheairline,

moisture or restrictions in air pipes or the use of hose connections of

impropersizeorpoorconditionsmayreduceairsupply.Gritorgum

deposits in the tool may cut power and may be corrected by cleaning

the air strainer and flushing out the tool with gum solvent oil or an

equalmixtureofSAE#10andkerosene.Ifoutsideconditionsare

in order, disconnect tool from hose and take tool to your Mac Tools
