GFN3490

Framing Nailer

Suitable for timber framing, roofing, joists and many other

tasks, this gas powered nailer is a real time saver.

Two batteries are provided, each will last up to 4,000 nails per charge.

There is a built in light to indicate low charge. Standard gas cartridges

are used, each with a life of approximately 1,200 nails. This nailer is

powerful but light to use, and able to

drive 51-90mm 34° ring shanked nails

into all timbers with ease.

An adjustable depth control, full

sequential action, effective air fil-

ters and a high temperature

warning lamp all contribute to

efficient use. A retractable

rafter hook is a clever idea, saving

an inavertant and possibly terminal

decent! With its Japanese built motor

this is a reliable tool for site or

workshop use.
