Safety
General warnings
• Never hold your hand or any other part of thebody within thepointing area when thegun is
connected with thecompressed air hose.
• Never aim thetool at any person or animal.
• Do not play with thetool.
• Never depress thetrigger if thenose of thetool is not aimed at theworkpiece.
• Always handle thetool with care.
• Never depress thetrigger or release thesafety catch while you are loading thetool.
• Use thetool solely for thepurpose for which it is intended.
• Never use thetool in such away that it is aimed at yourself or someone else in thework area.
• Do not use thetool as ahammer.
• Carry thetool by thehandle, not by theair hose.
• Never carry thetool with thetrigger depressed.
• Never modify thetool from theoriginal design.
• Always keep in mind that misuse or faulty handling of this tool could injure yourself and others.
• Never fasten or tape thesafety catch and/or trigger in activated position.
• Never leave atool unattended when it is connected to theair line.
• Do not use this tool if it does not have alegible warning decal.
• Do not continue using atool that is leaking air or is not working properly. Contact our
Customer Service for servicing.
• When using thetool, hold it in such away that no injury to thehead or body could occur
should afall in pressure or hard spots on theworkpiece cause therecoil force to increase.
• Do not nail too close to theedge of aworkpiece. Thenail could pass through theworkpiece
and cause damage.
• Disconnect from thecompressed air for transporting.
• Check frequently that both thetrigger and thesafety catch are working properly.
• Do not take apart any part of thetool.
• Do not use thenail gun if any part of it is damaged or missing.
• Avoid weakening thecasing by engraving, scribing or scratching it, etc.
• Always make note of where theelectric cable enters walls, floors and ceilings before you
begin to use thenail gun.
• Thecompressed air fitting for thenail gun must be of thequick-coupling type.
Theconnecting bit on thetool may not have arear valve so that some air remains under
pressure when thenail gun has been disconnected.

Compressed air feed and connections
Warning! To prevent accidents due to unintended firing, theoperator should always disconnect
thecompressed air:
• Before adjusting
• When cleaning thetool
• When removing ajammed nail
• When thetool is not being used
• When moving thetool to another work area
Warning!
• Use only compressed air in pneumatically driven tools. Never use acid or flammable gases to
drive thetool since themixture can explode and cause damage.
• Do not use gas in thecontainer or compressed air system when theair pressure could
exceed 8 bar as thetool could explode and cause damage.
• Thecompressor capacity must be sufficient to ensure anadequate air pressure and flow for
theintended use. Afall in pressure in thesystem can reduce thetool’s thrust.
See Technical data for setting theright pressure for thetool.
• Thecompressed air lines should be mounted on anincline, with thehighest point closest to
thecompressor. Aneasily accessed water separator should be installed at thelowest points.
Thewater separator should be emptied at least once aday or more often if needed. Dirt and
water in theair lines are themain cause of wear in pneumatically actuated tools.
• Thetool connecting bits should be equipped with areducing valve with water separator
directly at thepoint of connection. Afilter helps to achieve maximum effect at minimum wear.
Thefilter must have sufficient flow capacity for theintended mounting site or connecting
point. Thefilter must be kept clean if it is to be able to deliver clean compressed air to
thetool. See themanufacturer‘s instructions for proper filter care. Adirty or clogged filter will
cause afall in pressure, which reduces thetool’s effectiveness.
• Thepressure regulator must be adjustable from 0 to 8 bar.
• Theair hoses should tolerate at least 10.5 bar working pressure or 150 % of themaximum
pressure of which thesystem is capable. Themeter line should have aquick coupling so that
it can be loosened quickly from thenipple on thetool.
• Make sure that thecompressed air fed to thetool is unable to exceed themaximum
permitted working pressure (8 bar); install asafety valve if needed. Begin first with themeter
pressure set to thelowest recommended working pressure. See Technical data.
• Check that thetool is working properly by pressing thegun nose against apiece of wood
and pressing thetrigger one or two times.

Lubrication
• Note: Lubricate with afew drops of oil in theair fitting
before using thetool for thefirst time.
• Regular but moderate lubrication is required for best
effect. Oil fed through theair fitting lubricates only
thetrigger valve; theother internal components
are oiled at thefactory and normally do not require
lubrication. Do not use flushing oil or additives since
such lubricants cause more rapid wear on thetool
packings and rubber cushion, which results in poorer
results and makes more care necessary.
• Pour some oil in thetool’s connecting nipple one
or two times daily. Only afew drops (1–2) of oil are
needed thefirst time. Too much oil merely clogs
thelines and is visible when air is released.
• Make sure that themagazine’s pusher moves
smoothly and not sluggishly by keeping it clean and
well-oiled. Also lubricate theimpact pin itself with
afew drops of oil at every use.
Using in the cold
In cold weather near or below 0 °C moisture may freeze in thelines and cause thetool not to work
well. We recommend using anair lubricant or permanent antifreeze (ethylene glycol) as lubricant.
Note! To prevent frost or ice forming in thetool’s valves and mechanisms, which can cause
thetool to malfunction, avoid storing thetool in acold place.
Warning!
To prevent serious eye injury from flying nails and/or slivers theoperator and others in theworking
area must be equipped with eye protection that covers both thefront and thesides when loading,
using or servicing thetool. Glasses without eye protection on theside and face masks do not
give adequate protection!
Warning symbols on tool
Read theinstructions
for use.
Theuser and other persons
in thework area must use
protective glasses and
hearing protection.
Thetool should not be used on
scaffolding or ladders. Do not use
thenail gun if thefastener could
shoot through something and hit
someone on theother side.
Thegun is equipped with
asafety trigger.

thewarning text on thenail gun is legible.
2. Always disconnect thetool from theair line when it is not being used. Empty themagazine
and press thetrigger several times to empty theair from thetool before loading, servicing or
trouble-shooting.
3. Select themethod of use. Check that you have theright trigger attached. Change trigger if needed.

Preparations
Safety rules while loading
• Never hold your hand or other part of thebody within range of thetool’s pointing section.
• Never aim thetool at yourself or anyone else.
• Do not press thetrigger or push thesafety catch down since it could unintentionally be
activated with therisk of injury.
Loading

B. Repeated ring
Before using check that theorange trigger (for repeated firing) is attached to thenail gun.
1. Hold tool firmly and press thetrigger (3).
2. Press thetool against thework surface to depress thesafety catch thereby causing thetool to fire.
3. Hold in thetrigger (3), move to thenext spot and repeat from step 2.
Function and safety checks
Warning! Remove all nails from themagazine before doing afunction check.
1. Always detach thetool from theair line.
2. Empty themagazine and press thetrigger repeatedly to empty theair from thetool.
3. Connect theair hose but do not touch thetrigger. Press thesafety catch against thework surface.
Tool must not fire!
4. Hold tool free (do not press thetool nose against something), and press thetrigger (take care
not to point thetool toward yourself or any one else). Tool must not fire!
5. Press thesecurity catch against theworkpiece and depress thetrigger. Tool must fire!.
Setting the impact force
A. Adjust the impact force with pressure regulator on air hose
If thenail has not been driven deep enough first check whether theimpact depth adjusting dial (2)
is set at themaximum nail depth. If it is at themaximum raise theair pressure by 0.5 bar
increments bar and check with thenailing control after each increment. Do not exceed themax.
working pressure (8 bar).
If thenail has been driven in too deep, reduce theair pressure by 0.5 bar at atime, checking
theresult each time. Do not go below theminimum recommended working pressure (5 bar).
Always work with thelowest possible working pressure. This minimizes thenoise and vibration
levels and theinternal components of thenail gun will last longer.
