METHODS OF OPERATION

This Nailer is equipped with the push lever and does not operate unless the push lever is depressed (upward position).

There are two methods of operation to drive nails with this Nailer.

They are:

1.Intermittent operation (Trigger fire):

2.Continuous operation (Push lever fire):

(1)Intermittent operation (Trigger fire)

1 Position the nail outlet on the workpiece with finger off the trigger.

2 Depress the push lever firmly until it is completely depressed.

3 Pull the trigger to drive a nail.

4 Remove finger from the trigger.

To drive another nail, move the Nailer along the workpiece and repeat this procedure.

Push Lever

(2)Continuous operation (Push lever fire)

1 Pull the trigger with the Nailer off the workpiece. 2 Depress the push lever against the workpiece to

drive a nail.

3 Move the Nailer along the workpiece with a bouncing motion.

Each depression of the push lever will drive a nail. As soon as the desired number of nails have been driven, remove finger from the trigger.

WARNING

Keep your finger off the trigger except during fastening operation, beacuse serious injury could result if the push lever accidentally contacts you or others in work area.

Keep hands and body away from the discharge area. The nailer with contact trip mechanism may bounce from the recoil of driving a fastener and unwanted subsequent fastener may be driven, possibly causing injury.

Some types of loaded nails can spark out of the muzzle during a nail driving operation. Exericise caution!

THE OPTIONAL SEQUENTIAL TRIP MECHANISM (SINGLE SHOT PARTS) is for use where precision fastener placement is desired and must be operated in accordance with the following “Method of Operation”.

You must first depress the push lever (upward position) where you wnat to drive a nail and then pull the trigger. After the each nail is driven, completely release the trigger and lift the tool off the work surface. An OPTIONAL SEQUENTIAL TRIP MECHANISM may reduce the possibility of bodily injury to you or others in the work area. This is because it is less likely to drive an unwanted nail if you keep the trigger pulled and accidentally bump the push lever against yourself or others. An OPTIONAL SEQUENTIAL TRIP MECHANISM may also reduce the speed of operation compared to the standard contact trip mechanism.

NOTE:

Both STANDARD CONTACT TRIP MECHANISM and OPTIONAL SEQUENTIAL TRIP MECHANISM are safe if used as described above and accroding to all warnings and instructions.

Always handle nails and package carefully. If nails are dropped, collating paper may be broken.

After nailing:

1)disconnect air hose from the Nailer;

2)remove all nails from the Nailer;

3)supply 2 – 3 drops of Hitachi pneumatic tool lubricant into the air plug on the Nailer; and

4)open the petcock on the air compressor tank to drain any moisture.
