moving parts andmay cause injury. For outdoor work, rubber gloves and non-slip footwear are advised.
Wear a protectivehair net tocontain long hair.
4.Takeprecautions with compressedair. Do not disconnect air hoses ortools when theline is under
pressure. Close offair supply andrelease pressure first.Do not pointtools or directcompressed air at
people or animals.
5.Observe workarea environment. Do not expose air tools to rain or wet conditions. Do not use air tools
in close proximityto flammable liquidsor gases. Thework area shouldbe well litand ventilated.
6.Keep pets,untrained operators andchildren away.Children should be kept away fromthe work area.

12.When changingtools or accessories.Always closeoff air supplyand release pressure before
attempting to loosenany connection.
13.Beware oftemperature extremes. The expanding air causes the air tools to run very cold. Light
gloves are advisablefor operator comfort.Conversely, thecylinder head and air delivery pipe of the
compressor tank willrun quite hot.Avoid contact.
14.Maintain toolswith care. For efficient andsafe operation, toolsshould be keptclean. Check the
connections and hoses.If damaged theyshould be replaced.
15.Avoid unintentional triggering. Do not carry the tool or connect it with your finger on the trigger.
16.Do notabuse hoses. Do not carry tools by the hose or use the hose to drag the compressor. Protect
hoses from heat,oil, and sharpobjects. Avoiddraping the hose over the compressor cylinder head.
17.Storage. When not inuse, air toolsshould be storedin a dryarea that isnot accessible tochildren.
18.Stay alert.Do not usewhen you aretired or underthe influence ofalcohol and drugs.Use common
sense and payattention to avoidserious injury.
19.Remove keysand spanners. Do not forget to remove any adjustment keys, spanners, or wrenches
before operating thetool.
20.Do notleave unattended. Do not leave the compressor operating while unattended for extended
periods of time.If you havefinished using thecompressor and associatedtools, switch offthe air
supply and removethe plug.
21.Use onlycompressed air.This tool isintended for usewith compressed aironly. Neverattempt to
operate the toolusing compressed bottledoxygen or combustiblegases.
22.Use propersize and typeof air pressureline and fittings.Air hosesrated for amaximum of 150PSI or
Greater must beused with thistool.
OPERATING INSTRUCTIONS
GENERAL
1.Shut offthe air supply, disconnect air hose and releasepressure when changingbits.
2.Only operatethis tool withinthe recommended pressurerange 60 90PSI. Use outsidethis range will
cause poor performance,excessive wear andpossible danger.
3.Safety glassesmust always beworn for eyeprotection. Earplugs arestrongly recommended when
operating for longperiods.
TOOL SET UP
Fig. 1 (Above)shows an optimalset-up that includesan inline filter, regulator and oiler. All of these
components are soldseparately through NorthernTool+ Equipment.
NOTE: If you arenot using anautomatic oiler system,before operation, adda few dropsof Pneumatic
ToolOil to theairline connection.Add a fewdrops more afteran hour ofcontinual use.
1.Prepare the1/4" air nipple(#37) to connectto the airinlet on theair drill. First,wrap the 1/4"air nipple
with pipe threadseal tape (notincluded) before threadingit into theinlet. Connect the3/8" I.D. airhose
(not included) toa quick-disconnect coupler(not included) andthen to theair nipple.
2.Turn on the air pressure on your compressor to 90 PSI. Do not exceed the recommended air pressure of
90 PSI.
3.Check theair connection forleaks.
AIR SUPPLY
WARNING: Ensure the airsupply is cleanand does notexceed 90 PSIwhile operating thetool. Too
much air pressureand unclean airwill shorten theproduct life dueto excessive wear, and may cause
damage and/or personalinjury.
1.Make surethat the airvalve (or trigger)is in the"off" position beforeconnecting to the air supply.
2.An airpressure of 90psiis required.
3.Drain theair tank daily. Water in the airline can damage the tool.
4.Clean theair inlet filterweekly.

5.Line pressureshould be increasedto compensate forlonger air hoses(over 26 feetor 8 meters).The
hose diameter shouldbe 3/8" I.D.
6.Keep thehose away fromheat, oil andsharp edges. Checkthe hose forwear and makecertain that all
connections are secure.
LUBRICATION
NOTE: It is importantthat the toolis properly lubricatedat all timesto ensure efficientoperation and to
avoid premature componentwearing. Use onlyrecommended lubricants, speciallymade for pneumatic
applications. Substitutes mayharm the rubbercomponents, e.g. O-ringsand other rubberparts.
1.Always lubricatethe tool byintroducing a fewdrops of airlinelubricating oil intothe air inletof the tool
before use.An automatic in-linefilter-regulator-lubricator is recommendedin cases wherethe tool is
used regularly asit increases toollife and enablessustained operations.
2.In the eventthat it becomesnecessary to storethe tool foran extended periodof time, ensureit is
thoroughly lubricated beforeuse. The toolshould be run for approximately 30 seconds to ensure oil is
Evenly distributed throughout.
APPROPRIATE USAGE
1.Run thecompressor and adjustthe compressor regulatorto the correctoperating range of6090 PSI.
2.Open theoutlet tap ofthe compressor tothe drill connection.
3.Select thedirection of rotationand press thetrigger to operate.
WARNING: When changing bits,shut off theair supply to the tool, disconnect drill from air hose
and release thepressure first, toavoid accidental operation.
OPERATIONAL HINTS
1.Always ensurethat the workpiece is firmlyclamped, so thatyou can use2 hands toguide and control
the drill.
2.When drillingwood, to preventsplintering on thereverse face whenthe drill breaksthrough, clamp a
scrap piece ofwood beneath thepoint where youare drilling.
3.When drillingmetals, mark thepoint to bedrilled using acentre punch toassist in startingthe hole in
the correct place.
4.To prevent damage to the drill, apply coolant to the bit if necessary, but do not wetthe tool itself.
5.When drillingwood, plastic, hardrubber, orcast iron nolubricant is needed.Use light mineraloil for
Brass or bronze.Use kerosene foraluminum. Use solubleoil for steeland other metals.
MAINTENANCE
WARNING! Disconnect the toolfrom the airsupply before changingaccessories, servicing or
performing maintenance. Replaceor repair anydamaged parts immediately. Use genuine parts only.
1.Lubricate theair tool dailywith a fewdrops of airtool oil drippedinto the airinlet.
2.Clean thetool after use.DO NOT usea worn, or damaged chuck.
3.Loss ofpower or erraticaction may bedue to thefollowing:
· Excessive drain onthe airline. Moistureor restriction inthe air lineexists. Incorrect sizeor type ofhose
connectors being used.Toremedy, checkthe air supply.
· Grit or debrisdeposits in thetool may alsoreduce performance.
4.When notin use, disconnectthe tool fromthe air supply. Clean thetool and storeit in asafe, dry,
Childproof location.
