4. Driving nails into concrete

CAUTION

○ Use hardened nails designed for use with concrete.

○ Place the nailer vertically over the location into which

the nail is to be driven.

○ Do not drive nails directly into concrete or attach metal

plates directly onto it.

○ Do not drive nails into the edge of concrete.

○ Do not use the nailer in locations from which other items

are suspended (suspended pipes, etc.).

NOTE

Only use the nailer on concrete that has not yet set,

soon after it has been poured.

Using the nailer on hardened concrete may result in

bent nails and nails being insuﬃ ciently driven in.

[Selecting hardened nails for use with concrete]

Select nails with a concrete intrusion depth of between

10 to 15 mm.

NOTE

The nails will not be driven in suﬃ ciently if the concrete

intrusion depth is deeper than 15 mm.

5. Adjusting the nail-driving depth

CAUTION

When making adjustments, be sure remove your ﬁ nger

from the trigger. When making adjustments, be sure

that the nail outlet is not facing downward and that

body parts or other people are not in the path of the nail

outlet.

○ Adjusting the adjuster (Fig. 14)

Carry out test driving. If the nails are too deep, turn the

adjuster to the shallow side (

If the nail depth is too shallow, turn the adjuster to the

deep side (

Depth is changed 1 mm with each rotation of the

adjuster.

mark).

NOTE

○ When adjusting the adjuster, it does not rotate more

than 3 mm from the deepest point where a nail goes

down. Do not rotate the adjuster by force beyond that

point.

○ The nail-driving depth can also be adjusted by changing

the air pressure used. Carry this out together with

movement of the adjuster. Using a high air pressure that

does not match the nail-driving resistance will shorten

the life of this nailer.

6. Cutting oﬀ the sheet

Tear oﬀ the output sheet in the direction of the arrow

when using the sheet collated nails (Fig. 16).

7. Using the blow nozzle

CAUTION

○ Be sure to release your ﬁ nger from the trigger before

using the blow nozzle.

○ Do not point the air outlet at a person.

○ Do not use the blow nozzle with the push lever left ﬁ t.

This Nailer has a blow nozzle that blows out wood shavings

which occur during work.

Press the knob with your thumb to use the blow nozzle (See

Fig. 17).

NOTE

○ When the blow nozzle is used for a long time, the nailing

force may degrade temporarily. In this case, allows the

air supply pressure to stabilize before starting work.

○ Oil in the body or drained water from the compressor can

sometimes spout out of the air outlet. It is recommended

that you once conduct a test before use and see if

such phenomenon happens at an environment where

spouted oil will cause any inconvenience.

8. How to use nosecap

CAUTION

Remove the hose from the nailer and release the

compressed air before installing or removing the

nosecap to prevent accidental nail ejection.

○ Attach the nose cap on the tip of the push lever when

you wish to protect the surface of wood, etc., from

scratches.

(1) Attaching and detaching nose cap

The nose cap can be attached by simply pressing it into

the push lever.

Press it in until a convex part inside the nose cap enters

into a hole of the push lever. (Fig. 18)

For removal, insert a thin rod such as a screw driver into

the gap on the back of the push lever, and then pull it

out.

(2) Safekeeping of nose cap

Put the removed nose cap in a space behind the

magazine for safekeeping. (Fig. 19)
