maintenance of the tool, read this instruction manual
before using the tool.
General safety
• Do not permit those uninstructed to use the tool.
• No horseplay. Respect the tool as a working
implement.
• Do not operate when under the influence of alcohol,
drugs or the like.
• Never alter the tool.
Personal protective equipments
• Always wear safety glasses to protect your eyes from
dust or fastener injury.
WARNING: It is an employer’s responsibility to
enforce the use of safety eye protection equipment by
the tool operators and by other persons in the
immediate working area.
For Australia and New Zealand only
Always wear safety glasses and face shield to protect
your eyes from dust or fastener injury. The safety
glasses and the face shield should conform with the
requirements of AS/NZS 1336.
(Fig. 1)
• Wear hearing protection to protect your ears against
exhaust noise and head protection. Also wear light but
not loose clothing. Sleeves should be buttoned or
rolled up. No necktie should be worn.
Work area safety
• Never use the tool in enclosed or poorly ventilated
spaces. Otherwise carbon monoxide may cause
dizziness, nausea or unconsciousness.
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate the tool in explosive atmospheres, such
as in the presence of flammable liquids, gases or dust.
Operating the tool can create sparks which may ignite
the dust or fumes.
• Keep children and bystanders away while operating the
tool. Distractions can cause you to lose control.
• Illuminate the work area sufficiently.
• There may be local regulations concerning noise which
must be complied with by keeping noise levels within
prescribed limits. In certain cases, shutters should be
used to contain noise.
Safety devices
• Make sure all safety systems are in working order
before operation. The tool must not operate if only the
trigger is pulled or if only the contact arm is pressed
against the wood. It must work only when both actions
are performed. Test for possible faulty operation with
fasteners unloaded and the pusher in fully pulled
position.
• Do not play with the contact element: it prevents
accidental discharge, so it must be kept on and not
removed. Securing the trigger in the ON position is also
very dangerous. Never attempt to fasten the trigger. Do
not operate a tool if any portion of the tool operating
controls is inoperable, disconnected, altered, or not
working properly.
• Do not attempt to keep the contact element depressed
with tape or wire. Death or serious injury may occur.
• Always check contact element as instructed in this
manual. fasteners may be driven accidentally if the
safety mechanism is not working correctly.
Loading fasteners
• Do not load the tool with fasteners when any one of the
operating controls is activated.
• Use only fasteners specified in this manual. The use of
any other fasteners may cause malfunction of the tool.
Power source
• Use the tool only with the Makita genuine fuel cell.
• Do not touch liquid gas sprayed out of the fuel cell.
Contact with it may cause injury.
• Risk of fire and explosion. When handling the fuel cell
for the purpose of storage, transportation, inserting into
and taking out of the tool and disposal:
– do not expose to sunlight and to temperatures
exceeding 50
°
C (122°F);
– do not smoke;
– avoid sparks and open flame.
• Always remove the battery cartridge and remove all of
the fasteners:
– when unattended;
– before performing any maintenance or repair;
– before cleaning a jam;
– before moving the tool to a new location.
Operational safety
• Always check the tool for its overall condition and loose
screws before operation. Tighten as required.
• Handle the tool carefully, as there is high pressure
inside the tool that can be dangerous if a crack is
caused by rough handling (dropping or striking). Do not
attempt to carve or engrave on the tool.
• Stop the operation immediately if you notice something
wrong or out of the ordinary with the tool. An improperly
functioning tool must not be used.
• Do not point the ejection port at anyone in the vicinity.
Keep hands and feet away from the ejection port area.
• Always assume that the tool contains fasteners.
• Never point the tool toward yourself or anyone whether
it contains fasteners or not.
• Do not rush the job or force the tool. Handle the tool
carefully.
• Do not activate the tool unless the tool is placed firmly
against the workpiece.
• Never hold or carry the tool with a finger on the trigger
or hand it to someone in this condition. Accidental firing
can cause serious injury.
• Never use fastener driving tools marked with the
symbol “Do not use on scaffoldings, ladders” for
specific application for example:
