There are certain problems you may encounter when you
are using the Cordless Roofing Nailer that you will be able
to correct on the work site. The following field service
procedures are the only service procedures you should
attempt. Anything else that may appear wrong with the
Cordless Roofing Nailer should only be diagnosed and
repaired by a fully trained service technician. If you have any
reason to believe that your problem is beyond the service
procedures in this manual, contact your
Duo-Fast
®
representative immediately.
Servicing
Adjusting Depth of Drive
To adjust the depth of drive, loosen the work contact screw.
Set the work contact to the desired position and tighten the
screw.
Fuel Cartridge Check
DANGER
Wear safety glasses when performing this test. Never
perform this test near an open flame or sparks, while
smoking, or where the fuel may get into your eyes.
Battery Check
Periodically check the battery indicator light in the handle
of the Cordless Roofing Nailer. When encountering a
problem, the first step should always be to make sure the
battery has enough energy to operate the tool.
When the work contacting element is pressed on work
piece, the fan motor will turn on and blinking green light will
turn solid green. If the light blinks red or glows red, recharge
battery.
DANGER
Never attempt any maintenance of the Duo-Fast Cordless
Roofing Nailer without first removing the fuel cartridge
and battery. Maintenance should be started only after
the tool is completely inoperative.
If the
nailerʼs
fan operates and the light is green but the tool
will not cycle consistently or at all, check the fuel cartridge.
First remove the fuel cartridge from the tool and check the
“Best Use Before” date stamped on the bottom. If it is
beyond this date, the fuel cartridge may not consistently
dispense the proper amount of fuel – even if the cartridge
has never been used. To test if the cartridge still dispenses
fuel:
1. Hold the cartridge in the upright position with the flat
bottom toward the ground – this orientation is important for
a proper test.
2. Gently push the tip of the cartridge cap against a solid
object five times.
3. A small amount of fuel should be released all five times.
4. If fuel is not released every time it indicates the
cartridge is empty or expired* and must be replaced.
* Expired cartridges may dispense fuel when upside down
or sideways but will not work more than a couple of times
in the upright position because of the reduced internal
pressure (see page 9 for more information).
