Preparing the tool
Selecting compressor
Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph shows
the relation between nailing frequency, applicable pressure
and compressor air output.
Thus, for example, if nailing takes place at a rate of
approximately 40 times per minute at a compression of
0.8 MPa (120 PSI). a compressor with an air output over
3CFM is required.
Pressure regulators must be used to limit air pressure to
the rated pressure of the tool where air supply pressure
exceeds the tool’s rated pressure. Failure to do so may
result in serious injury to tool operator or persons in the vicinity.
Selecting air hose
Use an air hose with a large diameter and as short as
possible to assure continuous, efficient nailing operation.
With an air pressure of 0.80 MPa (120 PSI), an air hose
with an internal diameter of over 6.5mm (1/4”) and a length
of less than 20 m (6.6 ft.) is recommended when the interval
between each nailing is 0.5 seconds. Air supply hoses shall
have a minimum working pressure rating of 1.06 MPa
(150 PSI) or 150 percent of the maximum pressure
produced in the system whichever is higher.
CAUTION. Low air output of the compressor or a long or
smaller diameter air hose in relation to the nailing frequency
may cause a decrease in the driving capability of the tool.
Tool lubrication
This framing nailer requires lubrication BEFORE initial use
and BEFORE and AFTER each additional use throughout
its life.
1. Disconnect the air hose, turn the framing nailer so the air
inlet (12) is facing up. Place 2-3 drops of non detergent
oil into the air inlet. This should be done before and
after use. For proper lubrication, the tool must be fired a
couple of times after pneumatic nail gun oil is introduced.
Do not use air tool oil as it contains solvents which will
damage the nailer’s internal parts.
2. Lubricate the contact safety mechanism (1),
the latch (9), and the trigger (4) periodically.
3. After lubrication, run framing nailer briefly. Wipe off any
excess oil from the exhaust port (3). The work surface
can become damaged by excessive lubrication.
4. Framing nailer repairs must be done by a qualified and
experienced service dealer.
