2. Lock mechanism of the trigger

This device has a lock mechanism to prevent the

trigger from pulling.

Set the lock lever to “Lock” position to lock the trigger

in place.

To drive a nail, turn the lock lever to the “Free”

driving nails.

3. Lubrication

(1) Be sure to lubricate this nailer at least twice a day. To

lubricate, pour 10 to 15 drops of oil into the air plug

before and after using this nailer. The oil applied

before use lubricates this nailer; the oil applied after

use prevents rust.

(2) It is recommended using the recommended oil (SHELL

TONNA). Other applicable oils are listed. Never mix

two or more types of different oils.

4. Nose Selection and Switching

This nailer allows you to switch the nail outlet between

two sizes to extend the range of usable types and

sizes of nails. Set the nose switch lever to select the

outlet size matching the head diameter of the nail to

be used as shown below (Fig. 3).

CAUTION

Be sure to disconnect the air hose before operating

the nose switch lever.

NOTE:

Be sure to switch to the appropriate nose for the nails

to be used. Selecting an inappropriate nose may

cause defective nailing or sparking. It may also cause

a nail jam, damage to this nailer or personal injury.

Press the knob down and swing the nail guide open.

(4) Close the magazine cover first and swing the nail

guide closed (Fig. 10).

(5) Lock the knob correctly.

Be careful not to deform the collated wires and not to

disengage the nails with the guide surface.
