performance.
(7) Check for misalignment or binding of moving
parts, breakage of parts, and any other condition
that may aff ect the Nailer's operation.
If damaged, have the Nailer serviced before using.
Because of high air pressure in the Nailer, cracks in
the surface are dangerous. To avoid this, do not drop
the Nailer or strike the Nailer against hard surfaces;
and do not scratch or engrave signs on the Nailer.
Many accidents are caused by poorly maintained
Nailers. There is a risk of bursting if the Nailer is

5. Air source

(1) Never connect to an air source that is capable
of exceeding 200 psi (13.7 bar 14 kgf/cm
regulator fails.
Over pressurizing the Nailer is able to result in
bursting, abnormal operation, breakage of the Nailer
or serious injury to persons.
DO NOT EXCEED 120 psi (8.3 bar 8.5 kgf/cm
Use only clean, dry, regulated compressed air at the
rated pressure or within the rated pressure range as
marked on the Nailer.
Always verify prior to using the Nailer that the air
source has been adjusted to the rated air pressure or
within the rated air-pressure range.
(2) Never use reactive gases such as oxygen,
carbon dioxide, combustible gases or any
bottled gas as an air source for the Nailer. Such
gases are capable of explosion and serious injury to
persons.
6. Others
(1) Be careful of double fi re and being hit by the
Nailer due to spring back ("recoil").
After driving a nail, the Nailer may recoil causing it to
move away from the work surface.
To reduce risk of injury always manage recoil by:
1) always maintaining control of the Nailer.
2) allowing recoil to move the Nailer away from work
3) not resisting recoil such that the Nailer will be
