3. AIR SUPPLY AND CONNECTIONS
Read section titled "SAFETY INSTRUCTTONS'.
DO NOT USE ANY POWER SOURCE EXCEPT AN AIR COMPRESSOR
The tool is designed to operate on comprsssed air. Do not operats the tool on any other highpressure
gas, combustible gases (e.9., orygen, acetylene, etc.) since there is the danger ol an explosion. For this
reasor\ absolutely do not use arrything other fran an air compressot to operate the tool.
OPERATE W]THN THE PROPEB AIR PRESSURE RANGE
The tooldesigned to operate wilhin an air pressure r,ange ol70 to ltX) p.s.i. {5 to 7 bar.)
The pressure should be adjusted !o the type of the work being lastened. The tool shall never be
operated when tre operating pressuro exceeds 120 p.s.i. (8,bar.)
DO NOT OPERATE THE TOOL NEAR A FLAMMABLE SUBSTANCE
Never operate lhe tool near a flammable substance (e.9., thinneq gasoline, etc.). Volatile fumes lrom
frese substances could be drawn into the compressor and compressed together with he air and this
could result in an explosion.
DO NOT USE AWRONG FITTINGS
The connec{or on the tool must not hold pressure when air supply is disconnected. lf a wrong fitting is
used, the toolcan remain charged with air after disconnecfingand,thus will be able to drive a faslener
even after the air line b disconnected, possibly causing inlury.
DTSCONNECT THE AIR SUPPLY AND EMPTY THE MAGAZINE WHEN THE TOOL IS NOT IN USE
Always dsconnect the air supply lrom the tool and empty the magazine when operation has been
completed or suspended, when unaltended, moving to a differenl work area, adjusting, disassembling,
or repairing lhe tool, and when dearing a jammed fastener.
FITIINGS: lnstall a mde plug on the toolwhich is free flowing and wNch will release
air pressure from the tmlwhen disconnected lrom the supply source.
HOSES: Hose has a min. lD d 114- tG mrn) and mar length of no more than 17- (5
meters).
The supply hose should contain a fitting thal will provide "quick disconnecting' from
the mde plug on the tool.
SUPPLY SOURCE: Use only dean rogulated cnmpressed air as a porer source for
the tool.
}PIECE AIRSET (Air filter, Regulator, Oiler):
Hefer to TOOL SPECIFICATIONS lor setting the correcl operating prsssure for the
tool.
NOTE:
A filter wi[ help to get tlre best performance and minimum wear frorn ths tool because dirt and waler ln
the air supply are maior causes of wear in the tool,
Frequont but not ex@ssive, lubrication is required for the best performarrce. Ol added thru the air line
cornection will lubricale the inlernal pads.

4. INSTRUCTIONS FOR OPERATION
Read section titled "SAFETY INSTRUCTIONS".
1. EEFOBE OPERATION

2. OPEBATION
Wear safety glasses or goggles danger to the eyes always exists dr.p to the possibility of dust being
Qlowl up by the exhausled air or ol a lastener llying up dueto-the,improper handling of the tool. For
these reasons, safety glasses or goggles shall always be wom when operating the tool.
The employer andlor user must ensure that proper eye prolection is wom. Eye protection equipment
must conform to lhe requirements of the Arnerican National Standards Institule, ANSI 2S7.1 (Councit
Directive 8g68dEEC of 2l DEC. 1989) and provide both frontal and side protectiori:
The employer is responsibla lo enforce the use of eye protection equipment by the tool operator and all
other personnel in the work area.
NOTE: Non-sida shielded spectacles and face shields alone do not provide adequato protec{ion.
Keep hands and body away from the discharge outlet when driving he fasteners because ol dangerots
of hitting the hands or body by mistake.

MODEL IDENTIFICATION
CONTACT TRIP
The common operating procedure on "Contact Tdp' tools is for the operalor to contact the work to
actuate the tdp mechanism while keeping the trigger pulled, thus driving a fasteoer each time the work
is contacted. This will allow rapid fastener placement on many jobs, such as sheathing, decking and
pallet assembly.
All pneumatic tools are subiect to recoil when ddving fasteneis. The toolmay bounce, releasing the trip,
and if unintentionally allowed to recontact the work surface with the trigger still actuated (finger still
holding trigger pulled) an unwanied second fasiener will b€ driven.

SEqUE}TNAL TRIP
The Sequential Trip requires the operator to hold the tool against the work before pulling ttre trigger. This
makes accurate fastener placement easier, for instance on lramirq, toe nailing ard crating applications.
The Sequential Tdp allows exact fastener location withcjut the possibility of driving a second fastener
on recoil, as described r,nder tontact Trip'.
The Sequential Tdp Tool has a positive satety advantage because it will not accidentalty drive a
lastener if the tool is contacted against the workor anything els+while the operator is holding the
trigger pulled.

5. MAINTAIN FOR PERFORMANCE
O oo HoT FIRE THE NAILER wHEN IT Is EMPTY
O USC A S.PIECE AIRSET
Failure to use a 3-priece airset allows the moisturs and dirt inside compressor to pass into the tool
directly. This causes rust and wear, and resulls in a poor operating pedormanca. The hose length
bstween airset and tool should be no longer than 5 m sincs a longer length resutts in a reduction in air
pressure.
O UST RECOMMENDED OIL
The velocite or lubine oil should be used to lubricate the tool, Upon completion ol operations, place 2
or 3 drops ol oil into the air plug inlet with fre jet oiler. (Fecommended oil: tso vcg2)
O NSPCCT ANO MAINTAIN DAILY OR BEFORE OPERATION
Disconnecl air supply and empty the magazine when inspecting or maintaining the tool.
(1) Drain air line lilter and @mpressot
(2) Keep lubdcator filled in air &pieces set
(3) Clean lilter element of air 3aieces set
(4) Tlghten all screws
(5) Keep contact arm moving smoothly
6. STORING
O Wfren not in use for an extended pedod, apply a thin coat of the tubdcant to the steel parts to avoid
rust.
O Do not store rte bd in a cold weatfier environment. Keep the tool in a warm area.
O When nol in use, lhe toolshould be stored in a warm and dry place. Keep or.rt ol readr ol cfrildren.
O All quality tools will eventualiy require servicing or reptacement of parts because of wear from the
normaf use.
7. TROUBLE SHOOTINCJREPAIRS
The troubleshooting and/or rcpairs shall be carried out only by the MAJ( CO., LTD. authorised distrihrrors
or by other specialists.
Supplement to the operating instruction
Aocording lo the European Norm EN 792-13 the regulation is valid from 0't.01.2001 trat all fastener
driving tools with contact actuation musl be marked with the symbol "Do not use on sbaffoldings,
