Narrow crown construction staplers are used for cabinets, casebacks, drawers, insulation sheathing, underlayment, molding and trim. Unlike larger staplers designed to go around cables or wire without penetrating, a narrow crown <span class="search_hit">stapler</span> fastens material flush. It is best used on materials softer than hardwoods like oak.

🚫 Keep hands and body parts clear of immediate work area.  
🚫 Do not drive fasteners near edge of material, on top of other fasteners, at too great of an angle, or with the grain. ⚠️ Wear appropriate PPE.  
⚠️ Remove finger from the trigger when not driving fasteners.  
⚠️ Disconnect the tool from the air supply when a. Unattended, b. Performing any maintenance or repair, c. Clearing a jam, d. Moving the tool to a new location.

# Tool Safety

<div class="level1" id="bkmrk-">  
</div>### Personal Protective Equipment

⚠️ 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.

### Common Hazards

**Unintentional Firing**

<div class="level3" id="bkmrk-be-sure-the-trigger-">- <div class="li">Be sure the trigger is released before connecting to the air supply.  
    </div>
- <div class="li">Keep fingers away from trigger when not firing.  
    </div>
- <div class="li">Always assume the tool contains fasteners.  
    </div>

</div>**Double Firing**

<div class="level3" id="bkmrk-when-using-the-bump-">- <div class="li">When using the bump action trigger, be careful of unintentional double fires resulting from tool recoil. Unwanted fasteners may be driven if the contact trip is allowed to accidentally re-contact the work surface.   
    </div>

</div>To Avoid Double Fires:

<div class="level3" id="bkmrk-do-not-engage-the-to">- <div class="li">Do not engage the tool against the work surface with a strong force.  
    </div>
- <div class="li">Allow the tool to recoil fully after each actuation.  
    </div>
- <div class="li">Use sequential action trigger.  
    </div>
- <div class="li">When bump actuating the nailer, always keep tool in control. Inaccurate placement of tool can result in misdirected discharge of a fastener.  
    </div>

</div>**Protruding Fasteners**

<div class="level3" id="bkmrk-drive-the-nail-perpe">- <div class="li">Drive the nail perpendicular to the grain to reduce risk of unexpected protrusion.  
    </div>
- <div class="li">Be aware that when the tool is being utilized at pressures on the high end of its operating range, nails can be driven completely through thin or very soft work material. Be aware of material thickness and set depth appropriately.  
    </div>
- <div class="li">Always disconnect air supply and avoid contact with trigger during depth adjustments.  
    </div>

</div># Tool Care

<div class="level1" id="bkmrk--1">  
</div>## Care

Disconnect the tool from the air supply and remove fasteners from magazine before making adjustments or personal injury may result.

##### Daily Maintenance

</div></div>##### Cleaning

Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

# Operation

<div class="level1" id="bkmrk--2">  
</div>### Set Up

*This nailer is designed to be used without oil.*

<div class="level3" id="bkmrk-before-you-use-the-n">1. <div class="li">Before you use the nailer, be sure that the compressor tanks have been properly drained.  
    </div>
2. <div class="li">Wear proper eye, hearing and respiratory protection.  
    </div>
3. <div class="li">Lock the magazine release in the back position and remove all fasteners from the magazine.  
    </div>
4. <div class="li">Check for smooth and proper operation of contact trip and pusher assemblies. Do not use tool if either assembly is not functioning properly. NEVER use a tool that has the contact trip restrained in the up position.  
    </div>
5. <div class="li">Check air supply. Ensure that air pressure does not exceed recommended operating limits; 70 to 120 psi, (4.9 to 8.3 bar, 5 to 8.5 kg/cm2).  
    </div>
6. <div class="li">Connect air hose.  
    </div>
7. <div class="li">Check for audible leaks around valves and gaskets. Never use a tool that leaks or has damaged parts.  
    </div>

</div>## Inspection

Before you start using the <span class="search_hit">stapler</span> you are expected to do an initial inspection and access its readiness for use. Consult the checklist at the end of this document as well as the detailed processes here.

### Loading

⚠️Release the trigger and contact trip.  
⚠️Detach the air supply.

<div class="level3" id="bkmrk-read-all-safety-warn">1. <div class="li">Read all Safety Warnings before using tool.  
    </div>
2. <div class="li">Connect the tool to air supply.  
    </div>
3. <div class="li">Push the magazine release (F) and slide magazine (E) to open chamber.  
    </div>
4. <div class="li">Position nailer on a stable surface so contact trip is pointing upward and away from you.  
    </div>
5. <div class="li">Insert fasteners into the chamber.  
    </div>
6. <div class="li">Slide magazine until it clicks, securing the magazine.  
    </div>

</div>### General Operating Instructions

*The tool can be actuated using one of two modes: single sequential action trigger mode and bump action trigger mode.*  
**Sequential action trigger - Red trigger**  
The sequential action trigger’s intended use is for intermittent fastening where very careful and accurate placement is desired.  
To operate the nailer in sequential action mode:  
\- Depress the contact trip firmly against the work surface.  
\- Pull the trigger.  
*A fastener will be driven each time the trigger is pulled as long as the contact trip remains depressed which could result in accidental driving.*  
**Bump action trigger - Black trigger**  
*The bump action trigger’s intended use is for rapid fastening on flat, stationary surfaces.*  
Using the bump action trigger, two methods are available: place actuation and bump actuation.  
To operate the tool using the place actuation method:  
\- Pull the contact trip against the work surface.  
\- Pull the trigger.  
To operate the tool using the bump actuation method:  
\- Pull the trigger.  
\- Push the contact trip against the work surface. As long as the trigger is pulled, the tool will drive a fastener every time the contact trip is depressed. This allows the user to drive multiple fasteners in sequence.

##### Adjusting Depth

⚠️Release the trigger and contact trip.  
⚠️Detach the air supply.  
The depth that the fastener is driven can be adjusted using the depth adjustment next to the trigger of the tool. - To drive the fastener shallower, rotate the depth setting wheel (J) to the right. - To drive a fastener deeper, rotate the depth setting wheel (J) to the left.

#### Consumables

Staples are consumables. They may be purchased at the Protohaven shop or you can bring your own. This tool can accept:

<div class="level4" id="bkmrk-18-gauge%2C-1%2F2%E2%80%9C-%E2%80%93-1-1">- <div class="li">18 Gauge, 1/2“ – 1-1/2” (12.7 mm – 38.1 mm) length, 1/4“ (6.4 mm) crown staples</div>
