The Arrow FN50 is a 3-in-1 flooring nailer and stapler designed for professional and DIY flooring installation. It is compatible with 15.5GA flooring staples, 16GA L-cleats, and 16GA T-cleats ranging from 1-1/2" to 2" (38-50mm). Always wear safety glasses and ear protection during operation. Ensure the air supply is regulated between 70-100 PSI (5-7 bar) and that the work area is clear of debris.

Air Supply
Proper air supply is critical for tool performance and longevity:

- Use clean, dry, and regulated compressed air at 70-100 PSI (5-7 bar).
- A filter-regulator-lubricator system is required and should be placed as close to the tool as possible.
- Install a quick connector on the tool and a quick coupler on the hose for better performance.
- Ensure all connections are sealed to prevent air loss.
Loading and Operation
Loading Fasteners:

- Pull the pusher to the tail of the clip and hang it on the locating pin.
- Load the nails/staples from the upper part of the magazine.
- Press the locating pin again to release the pusher.
Operation:
- Test the driving depth on a sample piece of wood before starting.
- Connect the tool to the air supply.
- Hold the long arm and press the base to the work surface.
- Strike the hammer face with a hammer to drive the fastener.
- Lift the tool off the work surface.
Adjustments
Flooring Base Adjustment: Rotate the adjusting knob to match the thickness of your flooring. The tool is designed to fit 5/8" and 3/4" thick flooring wood. Ensure the mark on the knob aligns with the thickness specification.

Maintenance
Regular maintenance ensures tool longevity:
- Lubrication: Add a few drops of pneumatic tool oil through the air inlet before every operation or after 1 hour of continuous use. Do not use detergent oil.
- Cleaning: Keep the magazine and nose of the tool clean. Use non-flammable cleaning solutions if necessary, but do not soak the tool.
- Inspection: Regularly check for worn O-rings, seals, and loose screws.
Clearing Jams
If a fastener becomes jammed:

- Disconnect the tool from the air supply.
- Loosen the four screws holding the cover plate.
- Slide down and remove the cover plate.
- Remove the jammed fasteners.
- Replace the cover plate and tighten the screws.
Troubleshooting
If the tool is not performing correctly, check the following:
- Air Leaks: Tighten poppet actuator screws or replace worn O-rings.
- Lack of Power/Slow Cycle: Add lubricant or check if air pressure is too low.
- Intermittent Feeding: Replace damaged coil springs, ensure you are using standard fasteners, or clean the magazine and drive guide.
