Operating Instructions
1. Adjusting Depth
The depth control wheel allows you to adjust how deep the nails or staples are driven into the workpiece. This is crucial for protecting the work surface and adapting to different material thicknesses.
- Rotate the depth control wheel located on the top of the tool to increase or decrease the firing depth.
- Test on a scrap piece of material to ensure the desired depth is achieved before working on your main project.

Figure 4: The depth control wheel allows for precise adjustment of fastener penetration. Examples show fasteners driven at different depths.
For a visual demonstration of depth adjustment, watch the official product video below:

2. Firing Operation
The tool features a continuously shot mode for efficient work. To fire a fastener:
- Connect the tool to the air compressor.
- Press the safety nose firmly against the workpiece. The safety nose must be depressed for the tool to fire.
- Squeeze the trigger catch to drive a fastener.
- For continuous firing, keep the safety nose pressed against the workpiece, slide the nailer to a new position, release the trigger, and squeeze it again.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your WORKPRO pneumatic tool.
1. Regular Oiling
It is essential to add lubricant (included) regularly to all air tools. Apply a few drops of pneumatic tool oil into the air inlet before each use or after extended periods of operation. This lubricates internal components and prevents wear.
2. Jam Clearing
In the event of a fastener jam, follow these steps to clear it safely and efficiently:
- Disconnect Air Supply: Always disconnect the tool from the air compressor before attempting to clear a jam.
- Open Jam Clearing Latch: Locate the jam clearing latch at the front of the tool and open it.
- Remove Jammed Fastener: Carefully remove any jammed nails or staples from the firing mechanism.
- Close Latch: Close the jam clearing latch securely before reconnecting the air supply.
