Operating Instructions

Foreword

The Pneumatic Air Coil Nailer is a heavy duty, coil-fed, pneumatic nailer using compressed air as a power source. It is designed to install 1 – ¼” to 2 – ½” or 0.091” – 0.114” diameter nails of var ious lengths. It is widely used for the connections of frame and of both frame and felt. The tool has a magnesium alloy body and the cylinder cap is made of a light material that provides, high specif ic strength and rigi dity.

Power Source

This tool is designed to operate on clean, dry, compressed air at regulated pressures between 70 and 120 PSI (4.9 and 8.3 bar).
The preferred system would include a filter (C) Fig.2, a pressure regulator (A) Fig. 2, and automatic oiler (B) Fig.2 located as close to the tool as possible (within15 feet is ideal).
All compressed air contains moisture and other contaminants that are detrimental to internal components of the tool. An airline filter will remove most of these contam inates and significantly prolong the lif e of the tool. If an in­line oiler is not availa ble, place five or six drops of tool oil into the tool’s air inlet at the beginning of each workday.
Only disconnect the quick connector with the body tail portio n of the air inlet. No compressed air can be guaranteed when disc onnecting. If operation is incorr ect, the tool can remain charged with air aft er being disconnected and s till be able to fire a fastener, causing per sonal injury.
CAUTION: All line components ( hoses, connectors, filters, regulators , etc.) must meet 150% of the maximum system pressure. Please try to use a hose of ID 3/8” connecting the nailer with the compressor when disconnecting.
Do not connect this tool to a system with maximum potential. Only disconnect the quick connector being connected with the connector of the body tail portion air inlet , no compressed air can be guaranteed when moving to another location or handing the tool to another person.
Disconnect t he tool from the air supply before performing maintenance, clearing a jammed fastener, leaving the work area, moving t he tool to another location or handing the tool to another person.

Preparing the Tool

1. After reading and understanding this entire manual, connect the tool to the air supply. CAUTION:
− Keep the tool pointed away from yourself and others at all times.
− Always connect t he tool t o an air supply before loading fasteners.
− Do not load fasteners with the trigger or safety depressed.
− Always wear Z87 approved safety glasses and hearing protection when preparing or operating the tool.
− Never use a tool that leaks air or needs repair.
2. Depress the Handle (See A, F ig. 14) and open the Latch. Rotate the Upper Nail Housing to the side of the Body.
3. The Adjuster Plate can be moved up and down when twisting the Adjuster Nut (see B, Fig.15). Depending on the length of the nails, the Adjuster Plate should be adjusted correctly to the position indicated inside the Lower Nail Housing.
4. Place a coil of nails ov er the Lower Nail Housing. Uncoil enough nails to reach the Feed Hook and place the second nail between the teeth on the Feed Hook (see Fig. 16).
5. Close the Upper Nail Housing and depress the Latch (see Fig. 17).
6. Adjust the direct ional EXHAUST deflector (see Fig. 18), so that the exhaust air blast will be directed away from the operator. Grasp the deflect or and rotate it to the desired position for the current application.

Using the Tool

Complete all steps of Preparing the Tool before using the tool.

Firing Fasteners

This tool can be fired in two different ways: Trigger fire (single sequential) or bump fire (contact actuation). Trigger firing (single sequential): Turn the rotating shaft so that the tail of the rotating s haft is up (see Fig. 18A).
When the safety bracket is pressed against the work place, push the trigger repeatedly and the nails can be shot continuously.
1. Trigger firing: Put the nose on the working surface, lightly push the tool toward the working surface until the safe bracket is depressed, then press the trigger to fire the fasteners. This “trigger fire” method provides the most accurate f astener placement. In this method, the safety bracket can be adjusted downwards with the knob to avoid striking two nails at the same time.
2. Another method is to press the trigger assembly, then press the safety bracket repeatedly. The tool can repeatedly fire multiple fasteners. The tool will fire one fast ener when the safety bracket is pressed only one time. This method is working in the non-acc urate position, so use this method for the work effici ency to increase.
a. Original factory setting is sing le sequential trigger mo d e . b. Read and understand this manual before changing the trigger mode. Improper use may result in serious
injury.
c. Ma nufacturer assumes no responsibi lity f or any injuri es and losses caused by any improper use of this
tool.
CAUTION: Remove your finger from the trigger when not firing any fasteners. N ever carry the tool with your finger on the trigger; the tool will fire a f astener if the saf ety is pressed.
Keep the tool pointed at a safe direction at all times. Never attempt t o driv e a fastener into material that is too hard or at too steep an angle, or near the edge of
the work piece. The fastener can ricochet, causing personal injury. Disconnect the tool from the air supply before performing m aintenance, clearing a jammed fastener, leaving
the work area, moving the tool to another location, or handing the tool to another person. Clean and inspect the tool daily. Careful ly check for proper operation of trigger and safety mechanism. Do
not use the tool unless both the trigger and the safety mechanism are functional, or if the tool is leaking air or if it needs any other repair.

3. Driving depth will be increased or decreased by rotating the depth of the drive knob or adjuster (Fig. 19A). Test fire a fast ener and check the depth. If the nail is driven in too deeply, rotate the adjuster clock wise to make the safety bracket push downwards. Whereas, rotate the adjuster counter clockwise to make the safety bracket push upwards. Repeat this step to achieve the desired results (See Fig. 20).

Clearing a Jammed Fastener

1. CAUTION: Disconnect the tool from the air supply.
2. Open the latch, rotat e the lower housing and remove the nails of t he lower housing.
3. Use a slender, soft steel rod to drive the drive blade to its uppermost position. Use the needle nose pliers t o remove the jammed fastener (Fig. 21).
4. Follow the instruct ions in Preparing the Tool to reload fasteners.

Maintenance

Clean and Inspect the Tool Daily

Caution: Disconnect the tool from the air supply before cleaning and inspecting it. Correct all problems before
operating.
•
Check the filter of the compressor weekly and switch of the manual valve to drain water and other contaminants out.
•
Do not soak the tool in cleaning solutions. Such solutions can damage internal parts. The exposed portion of the small piston rod and t he feed hook must be kept clean.
•
Inspect the trig ger and safety mechanism to ensure that the system is complete and functional: no loose or missing parts, no bindi ng or sticking parts should be found.
•
Keep all screws tight. Loose screws can cause personal injur y or can damage the tool.
•
Check if there are any worn and dam aged parts. If there are any, please replace them immediately.
•
If the tool is used without an in-line oiler, place 5 or 6 dr ops of air tool oil into the air inlet of the tool at the beginning of each workday.
