CLEANING THE AIR FILTER

Attempts to go beyond these procedures could result in

serious personal injury or damage to the Cordless Framing

Nailer and voiding the warranty.

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.

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.

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.

Fuel Cartridge Check

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:

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.

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.

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).
