Finishing nail guns are powerful tools that can handle basic home improvement tasks as well as professional jobs. Use finishing nailers (also known as trim nail guns) to complete flooring and molding projects without one swing of a hammer. Finishing nails are thicker (15 or 16 gauge) and have a larger head than brad nails, which are used for light trim projects. While they may be more visible than brad nails, finishing nails are strong enough to secure large and heavy pieces of wood. You can cover them with putty to make them less noticeable. Use finishing nailers to attach heavy crown molding, affix large baseboards or install a new hardwood floor. You can also use them to put together cabinets and furniture.

The Tool Safety, Tool Care, Operation, section of this guide are what instructors use to ensure that you can use the equipment according to community expectations.

No Clearance Required. If you don't know how to use the tool ask for help.

🚫 Do not use this nailer for fastening electrical cables. 🚫 Do not fire fastener on top of another fastener, into surfaces too hard to penetrate, or too close to the edge of the workpiece.
🚫 Do not hold tool near body while firing. Tool recoil can cause injury.
⚠️ Wear appropriate PPE.
⚠️ Ensure the switch is in the off position before connecting to power source and/ or battery pack, picking up or carrying the tool.
⚠️ Remove finger from the trigger when not driving nails.
⚠️ Disconnect the tool from the power supply when a. Unattended, b. Performing any maintenance or repair, c. Clearing a jam, d. Moving the tool to a new location.

⚠️ Safety glasses, hearing protection, heavy duty gloves, and closed-toed shoes are required.

⚠️ All hair, clothing and accessories should be secured close to the body.

Unintentional Firing

• Be sure the trigger is released before connecting to power.
  
• Keep fingers away from trigger when not firing.
  
• Always assume the tool contains nails.
  

Balance and Tool Control

• Do not overreach. Keep proper footing and balance at all times.
  
• Do not attach the tool to your body.
  
• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against the body is unstable and can lead to loss of control.
  

Clean magazine, pusher, and contact trip mechanism. This permits smooth operation of magazine, reduces wear, and prevents jams. Clean tool with a clean, damp cloth. Do not oil or lubricate this tool. The use of oils, lubricants or solvents is not recommended as they tend to attract debris.

Blow dirt and dust out of all air vents with clean, dry air at least once a week.

Before you start using the nailer you are expected to do an initial inspection and assess its readiness for use.

1. Remove battery pack from tool and engage trigger lock-off.
2. Lock the pusher in the back position and remove all nail strips from the magazine.
3. Check for smooth and proper operation of contact trip and pusher assemblies.
4. Do not use tool if either assembly is not functioning properly.
5. NEVER use a tool that has damaged parts.

Secure loose workpieces using a vise or clamps to prevent movement while working.
⚠️Make certain the trigger lock-off button is engaged to prevent switch actuation before removing or installing battery.
TO INSTALL BATTERY PACK: Insert battery pack firmly into tool until an audible click is heard. Ensure battery pack is fully seated and fully latched into position.
TO REMOVE BATTERY PACK: Depress the battery release button and pull battery pack out of tool.

⚠️Keep the tool pointed away from yourself and others.
⚠️Never load nails with the contact trip or trigger activated.
⚠️The battery should always be removed and the trigger lock-off is engaged whenever any adjustments are made or when tool is not in use.
⚠️Keep fingers clear of pusher to prevent injury.

1. Insert fasteners into the bottom of the magazine.
2. Pull pusher downward until the nail follower falls behind the nails.
3. Release the pusher.

⚠️The contact trip needs to be depressed followed by a full trigger pull for each nail followed by a release of both the contact trip and trigger after each nail.

1. Fully depress contact trip against the work surface.
2. Fully pull trigger and motor will start. (nail will drive into work surface).
3. Release trigger.
4. Lift contact trip off work surface.
5. Repeat steps 1 through 4 for next application.

Note: There are work lights located on each side of the nailer. Work lights turn on upon depressing the contact trip. These work lights are for illuminating the immediate work surface only.

• The work lights will flash and then turn off completely to indicate low battery.
• The work lights will flash continually if a nail becomes jammed in the nose piece.

⚠️Always remove battery pack, engage trigger lock-off, and avoid contact with trigger during adjustments. The depth that the fastener is driven can be adjusted using the depth adjustment wheel on the side of the tool. Depth settings are on a sliding scale. The left side indicating the deepest and the right side indicating the shallowest.

1. To drive a nail deeper, rotate the depth adjustment wheel (3) downwards. This will slide the depth adjustment indicator (4) to the left on the scale.
2. To drive a nail shallower, rotate the depth adjustment wheel (3) upwards. This will slide the depth adjustment indicator (4) to the right on the scale.

1. Press pusher latch release button.
2. Manually slide nails towards the bottom of the magazine.
3. Open the jam clear door on the nosepiece to verify there are no nails remaining.

Nails are consumables. Please bring your own. This tool can accept 16 Gauge 1″ - 2.5″ nails.

If you encounter any of the issues listed in the Inspection area or have any other issues with the printer not working properly

• Update the physical Maintenance Tag at the machine
  • 🟢Green can be used without issue
  • 🟡Yellow can be used withcaution
  • ⛔Red cannot be used without hazard to either the user or the equipment
• Record issues at protohaven.org/maintenance. This notifies our staff and volunteer maintenance crew of any issues.

• Remove battery pack from tool and engage trigger lock-off.
• Rotate the stall release lever (6) on the tool to release the driver blade and clear the jam. If tool is still jammed follow steps 3-11 listed below.
• Pull pusher downward until it locks in place then tip the tool over so the nails slide freely out from the bottom of the magazine.
• Lift the jam clearing latch (7) then pull up to open front door (14).
• Remove bent nail, using pliers if necessary.
• If driver blade is in the down position, insert screwdriver or other rod into nosepiece and push driver blade back in position.
• Close the front door and engage the wire form (13) under the two arms (15) on the contact trip. Push jam clearing latch down (7) until it locks in place.
• Reinsert nails into magazine (see Loading the Tool).
• Pull pusher (10) downward until the nail follower (D1) falls behind the nails as shown in figure D.
• Reinsert battery pack.
• Disengage trigger lock-off (2), allowing the trigger to be actuated.

If the nailer is used in a rigorous application where all available energy in the motor is used to drive a fastener, the tool may stall. The driver blade did not complete the drive cycle and the jam/stall indicator will flash. Rotate the stall release lever (6) on the tool and the mechanism will release.
NOTE: The tool will disable itself and not reset until the battery pack has been removed and reinserted. If the unit continues to stall please review the material and fastener length to be sure that it is not too rigorous an application. If the driver blade does not automatically return to the home position after rotating the stall release lever, follow the instructions for clearing a jammed nail.
