Always wear safety glasses to protect your eyes
•
from dust or nail 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.
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.
Rushing the job or forcing the tool is dangerous.
•
Handle the tool carefully. Do not operate when
under the influence of alcohol, drugs or the like.
General Tool Handling Guidelines:
•
(1) Always assume that the tool contains
fasteners.
(2) Do not point the tool toward yourself or
anyone whether it contains fasteners or not.
(3) Do not activate the tool unless the tool is
placed firmly against the workpiece.
(4) Respect the tool as a working implement.
(5) No horseplay.
(6) Do not hold or carry the tool with a finger on
the trigger.
(7) Do not load the tool with fasteners when any
one of the operating controls is activated.
(8) Do not operate the tool with any power
source other than that specified in the tool
operating/safety instructions.
An improperly functioning tool must not be used.
•
Sparks sometimes fly when the tool is used. Do not
•
use the tool near volatile, flammable materials
such as gasoline, thinner, paint, gas, adhesives,
etc.; they will ignite and explode, causing serious
injury.
The area should be sufficiently illuminated to
•
assure safe operations. The area should be clear
and litter-free. Be especially careful to maintain
good footing and balance.
Only those involved in the work should be in the
•
vicinity. Children especially must be kept away at
all times.
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.
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.
Operate the tool within the specified air pressure of
•
0.44 - 0.83 MPa (4.4 - 8.3 bar) for safety and
longer tool life. Do not exceed the recommended
max. operating pressure of 0.83 MPa (8.3 bar).
The tool should not be connected to a source
whose pressure potentially exceeds 1.37 MPa
(13.7 bar).
Make sure that the pressure supplied by the
•
compressed air system does not exceed the
maximum allowable pressure of the fastener
driving tool. Set the air pressure initially to the
lower value of the recommended allowable
pressure (see SPECIFICATIONS).
Never use the tool with other than compressed air.
•
If bottled gas (carbon dioxide, oxygen, nitrogen,
hydrogen, air, etc.) or combustible gas (hydrogen,
propane, acetylene, etc.) is used as a power
source for this tool, the tool will explode and cause
serious injury.
Always check the tool for its overall condition and
•
loose screws
required.
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 nails unloaded and the pusher in
fully pulled position.
Make sure that the trigger is locked when the
•
change lever is set to the LOCK position.
Check walls, ceilings, floors, roofing and the like
•
carefully to avoid possible electrical shock, gas
leakage, explosions, etc. caused by striking live
wires, conduits or gas pipes.
Use only nails specified in this manual. The use of
•
any other nails may cause malfunction of the tool.
Never use fastener driving tools marked with the
•
symbol "Do not use on scaffoldings, ladders" for
specific application for example:
− when changing one driving location to
another involves the use of scaffoldings,
stairs, ladders, or ladder alike constructions,
e.g. roof laths;
− closing boxes or crates;
− fitting transportation safety systems e.g. on
vehicles and wagons.
Do not permit those uninstructed to use the tool.
•
Make sure no one is nearby before nailing. Never
•
attempt to nail from both the inside and outside at
the same time. Nails may rip through and/or fly off,
presenting a grave danger.
Watch your footing and maintain your balance with
•
the tool. Make sure there is no one below when
working in high locations, and secure the air hose
to prevent danger if there is sudden jerking or
catching.
