INSTALLATION

Selecting compressor

1. Nailing frequency (limes/min) 2. Compressor air output per minute (Umin) 3. 0.83 MPa (8.3 bar) 4. 0.74 MPa (7.4 bar) 5. 0.64 MPa (6.4 bar)

The air compressor must comply with the requirements of EN60335-2-34.
Select a compressor that has ample pressure and air output to assure cost- efficient operation. The graph shows the relation between nailing frequency, applica­ble pressure, and compressor air output.

Thus, for example, if nailing takes place at a rate of approximately 60 times per minute at a compression of 0.74 MPa (7.4 bar), a compressor with an air output over 55 liters/minute is required.
Pressure regulators must be used to limit air pressure to the rated pressure of the tool where air supply pressure exceeds the tool’s rated pressure. Failure to do so may result in serious injury to the tool operator or persons in the vicinity.

Selecting air hose

CAUTION: Low air output of the compressor, or a long or smaller diameter air hose in relation to the nailing frequency may cause a decrease in the driving capability of the tool.
► Fig.2

Use an air hose as large and as short as possible to assure continuous, efficient nailing operation.
With an air pressure of 0.49 MPa (4.9 bar), an air hose with an internal diameter of over 6.5 mm and a length of less than 20 m is recommended when the interval between each nailing is 0.5 seconds.
Air supply hoses shall have a minimum working pressure rating of 1.03 MPa (10.3 bar) or 150 percent of the maximum pressure produced in the system whichever is higher.

Lubrication

► Fig.3
To ensure maximum performance, install an air set (oiler, regulator, air filter) as close as possible to the tool.
Adjust the oiler so that one drop of oil will be provided for every 50 nails.
When an air set is not used, oil the tool with pneumatic tool oil by placing 2 (two) or 3 (three) drops into the air fitting. This should be done before and after use.
For proper lubrication, the tool must be fired a couple of times after pneumatic tool oil is introduced.
► Fig.4: 1. Pneumatic tool oil

FUNCTIONAL DESCRIPTION

CAUTION: Always disconnect the hose before adjusting or checking the function of the tool.

Adjusting the depth of nailing

► Fig.5: 1. Adjuster
To adjust the depth of nailing, turn the adjuster.
The depth of nailing is the deepest when the adjuster is turned fully in the A direction shown in the figure. It will become shallower as the adjuster is turned in the B direction.
If nails cannot be driven deep enough even when the adjuster is turned fully in the A direction, increase the air pressure.
If nails are driven too deep even when the adjuster is turned fully in the B direction, decrease the air pressure.
Generally speaking, the tool service life will be longer when the tool is used with lower air pressure and the adjuster set to a deeper depth of nail driving.

Hook

CAUTION: Never hook the tool at a high location or on a potentially unstable surface.
CAUTION: Do not hang the hook from the waist belt. If the nailer accidentally drops, it may result in misfiring and personal injuries.

► Fig.6
► Fig.7: 1. Hook
The hook is convenient for hanging the tool temporarily.

Air duster

CAUTION: Do not aim the ejection port of the air duster at someone. Also, keep your hands and foot away from the ejection port. If the air duster button is accidentally pushed, it may cause a personal injury.

CAUTION: Always check your surroundings before using the air duster. Blown dust or objects may hit someone.

CAUTION: Do not connect or disconnect the air hose while pushing the air duster button.

The air supplied to the tool can also be used as an air duster. You can clean the work area by pressing the button on the grip end.
► Fig.8: 1. Button

NOTICE: After using the air duster, the driving force of the tool will temporarily decline. Wait until the air pressure recovers in this case.

NOTICE: Perform a test blow if you use the air duster immediately after the oil was applied. The oil may be sprayed with the air.

ASSEMBLY

CAUTION: Always disconnect the hose before carrying out any work on the tool.

Loading nails

CAUTION: Load the same kind, size, and uniform length of nails when loading nails in the magazine.

1. Pull the sliding door while pressing down the lever to open the magazine.

Connecting air hose

CAUTION: Do not rest your finger on the trigger when connecting the air hose.
► Fig.13: 1. Air fitting 2. Air socket
Slip the aerial socket of the air hose onto the air fitting on the tool. Be sure that the air socket locks firmly into position when installed onto the air fitting.
A hose coupling must be installed on or near the tool in such a way that the pressure reservoir will discharge at the time the air supply coupling is disconnected.

OPERATION

CAUTION: Make sure all safety systems are in working order before operation.

Checking proper action before the operation

Before the operation, always check the following points.
— Make sure that the tool does not operate only by connecting the air hose.
— Make sure that the tool does not operate only by pulling the trigger.
— Make sure that the tool does not operate only by placing the contact element against the workpiece without pulling the trigger.

Driving nails

To drive a nail, place the contact element against the workpiece and pull the trigger.
► Fig.14

CAUTION: WITH THE TRIGGER HELD IN A HALF-PULLED POSITION, unexpected nailing could occur, if the contact element is allowed to re-contact against the workpiece or the other surface under the influence of recoil.

In order to avoid this unexpected nailing, perform as follows;

• Do not place the contact element against the workpiece with excessive force.
• Pull the trigger fully and hold it on for 1-2 seconds after nailing.

Removing jammed nails

WARNING: Always disconnect the hose before removing nails.
CAUTION: Do not use deformed nails or nail strips. Failure to do so causes poor nail feeding.

1. Open the sliding door and remove nails from the magazine.
   ► Fig.15

2. With the sliding door kept open, pull the latch to open the door and then remove the nails.
   ► Fig.16: 1. Latch 2. Door

MAINTENANCE

CAUTION: Always disconnect the hose before attempting to perform inspection or maintenance.
NOTICE: Never use gasoline, benzene, thinner, alcohol, or the like. Discoloration, deformation, or cracks may result.

Nails

Handle nail strips and their box carefully. If the nail strips have been handled roughly, they may be out of shape, causing poor nail feed.
Avoid storing nails in a very humid or hot place or place exposed to direct sunlight.

Maintenance of nailer

Always check the tool for its overall condition and loose screws before operation. Tighten as required.

With the tool disconnected, make a daily inspection to assure free movement of the contact element and trigger. Do not use the tool if the contact element or trigger sticks or binds.
When the tool is not to be used for an extended period of time, lubricate the tool using pneumatic tool oil and store the tool in a safe place. Avoid exposure to direct
sunlight and/or humid or hot environments.
► Fig.17

Maintenance of compressor, air set, and air hose

After the operation, always drain the compressor tank and the air filter. If moisture is allowed to enter the tool, it may result in poor performance and possible tool
failure.
► Fig.18: 1. Drain cock
► Fig.19: 1. Air filter
Check regularly to see if there is sufficient pneumatic tool oil in the oiler of the air set. Failure to maintain sufficient lubrication will cause O-rings to wear quickly.
► Fig.20: 1. Oiler 2. Pneumatic tool oil
Keep the air hose away from heat (over 60°C, over 140°F), and away from chemicals (thinner, strong acids, or alkalis). Also, route the hose away from obstacles that may
become dangerously caught on during operation.

Hoses must also be directed away from sharp edges and areas which may lead to damage or abrasion to the hose.
