Assembly / Installation

Follow the instructions below to prepare your tool for operation.

1.All tool operators and their immediate supervisors must become familiar with the operator safety instructions before operating the tool. The instructions begin on page 3 of this manual.

2.Included with each tool are one copy of these Operating/Safety Instructions and one copy of the Tool Schematic. Keep these publications for future reference.

3.Install a filter, regulator, lubricator unit and moisture trap on your air delivery system per the manufacturer's instructions for these devices. Additionally, install a pressure gauge as close as practical to the tool, preferably within ten feet.

4.Select hoses with a minimum inner diameter of 3/8 inches and a maximum length of 100 feet.

To reduce the risk of injury from a hose ! WARNING bursting, select hoses that are rated at

least 200 PSI.

5. Select fittings that are appropriately sized for the selected hoses. The tool and air hose must have a hose coupling such that all pressure is removed from the tool when the coupling joint is disconnected.

Never use non relieving couplers and/or female quick disconnect couplings on the tool. Non relieving couplings and

female couplings will trap high pressure air in the tool when the air line is disconnected. This will leave the tool charged with enough air after it has been disconnected to drive a nail. Only MALE pneumatic type air connectors should be fitted to the tool, so that high pressure air in the tool is vented to atmosphere as soon as the air line is disconnected.

6. Set the regulator at the air delivery system to a PSI that falls within the tool's operating range of 60 to 120 PSI. The correct pressure is the lowest pressure that will do the job.

7. If the operator is working at a bench or table, it is recommended to run the air line underneath the bench. A small tray under the bench top can hold the nail supply and the tool when not in use.

Operation

Actuation System

Your tool is equipped with two devices that require actuation before the tool will fire, the work contact element and the finger trigger. There are two selectable modes, built into the trigger, that determine how the tool fires nails.

“Sequential” Firing Mode: In “sequential” firing mode, there is a predetermined sequence required to fire a nail. The work contact element must first be depressed against the work piece. A nail will then fire when the trigger is depressed. To fire another faster, the work contact element must be removed from the work piece, the trigger must be released. The sequence can then be repeated.

“Bump” Firing Mode: In “Bump” firing mode, nails can be fired each time the work contact element is depressed with the trigger depressed. With the trigger continuously depressed, a nail will fire each time the work contact element is depressed against the work piece. This allows for nails to be fired at a faster rate.

Each mode is described in detail in the “Firing Modes” section of this manual.

Understand the differences between ! WARNING actuation modes for this tool. Using the

tool in an inappropriate mode may cause tool to react in an unexpected manner and may result in personal injury.

Verify the setting of the Selectable trigger ! WARNING switch before using the tool. Using the tool

before verifying the actuation mode may cause tool to react in an unexpected manner and may result in personal injury.
