Makita AT638A Instruction Manual

5 ENGLISH
Use an air hose as large and as short as possible to
assurecontinuous,efcientstaplingoperation.
Withanairpressureof0.49MPa(4.9bar),anairhose
with an internal diameter of over 6.5 mm and a length
of less than 20 m is recommended when the interval
between each stapling is 0.5 seconds.
Air supply hoses shall have a minimum working pres-
sure rating of 1.03 MPa (10.3 bar) or 150 percent of the
maximum pressure produced in the system whichever
is higher.
Lubrication
Toinsuremaximumperformance,installanairset(oiler,
regulator,airlter)ascloseaspossibletothetool.
Adjusttheoilersothatonedropofoilwillbeprovided
for every 50 staples.
Whenanairsetisnotused,oilthetoolwithpneumatic
tool oil by placing 2 (two) or 3 (three) drops into the air
tting.Thisshouldbedonebeforeandafteruse.
Forproperlubrication,thetoolmustberedacoupleof
times after pneumatic tool oil is introduced.

►1.Adjuster
Toadjustthedepthofstapling,turntheadjuster.
Thedepthofstaplingisthedeepestwhentheadjuster
isturnedfullyintheAdirectionshowninthegure.Itwill
becomeshallowerastheadjusteristurnedintheBdirection.
If staples cannot be driven deep enough even when the
adjusteristurnedfullyintheAdirection,increasethe
air pressure.
Ifstaplesaredriventoodeepevenwhentheadjusteris
turnedfullyintheBdirection,decreasetheairpressure.
Generallyspeaking,thetoolservicelifewillbelonger
when the tool is used with lower air pressure and the
adjustersettodeeperdepthofstapledriving.
Hook
CAUTION: Never hook the tool at high loca-
tion or on potentially unstable surface.
CAUTION: Do not hang the hook from the
waist belt.Ifthestapleraccidentallydrops,itmay
resultinmisringandpersonalinjuries.
