Problem
Possible cause
Inspection method
Corrective action
Fuel is not
sprayed.
• Fuel is leaking.
• There is no fuel.
• The metering valve
is not set properly.
• Press the stem five
or more times with
the fuel cell held
upright to check
whether fuel is
being sprayed.
• Set the metering valve
properly (and rotate the
valve to secure it in
place).
• Replace the metering
valve with a new one.
• Replace the fuel cell with a
new one.
• The bag in the fuel cell is
damaged.
• Fuel is not sprayed
when the fuel cell
is held upright, but
is sprayed when
the fuel cell is held
horizontally.
• Replace the fuel cell with a
new one.
• Insufficient sealing of the cup
and stem in the metering
valve.
• Check whether fuel
is leaking by
holding down the
stem.
• Replace the metering
valve with a new one.
• The nailer is left under a high
temperature condition.
The nailer is left in direct
sunlight or nails are driven
continuously. <Excessively
high concentration of gas>
• The main body is
hot due to
combustion heat.
• Allow the main body and
fuel cell to cool down.
• Replace the fuel cell with a
new one.
Fuel is
sprayed but
no
combustion
occurs.
• The nailer is left under a low
temperature condition.
0°C or lower temperature
<Low concentration of gas>
• The sprayed fuel is
in a liquid state.
• Warm up the fuel cell.
Instruct the customers on
such necessary measures
as putting the fuel cell in a
pocket or wrapping it in a
thermal insulating
material.
Fuel is sprayed
but no
combustion
occurs.
• The oxygen content of air is low
at such places as highlands at
an altitude of 1,500 meters or
more.
<Excessively high concentration
of gas>
• A large amount of
fuel is sprayed.
• Use the nailer where the
altitude is less than 1,500
meters.
