Preparing your Axminster White Palm Nailer for use
Using the Air Nailer
12
Check your air supply system is on, and air is avail-
able in the gallery. (Check your in line oilers, if fitted
have
sufficient oil in the reservoirs). Turn on the air to the
hose line. Set the required pressure on the regula-
tor
(We suggest 85 psi).
Note. Remember you have to bleed air through
the regulator to achieve the set pressure, do this
by
opening the hose line using a blow gun or
duster, and setting the regulator whilst the air is
flowing.
Using the oil supplied in the small oiler bottle, put
2-3 drops into the air connector (See Fig 6 &6a). It is
always a good policy to add at least a drop of oil to
the tool prior to the first use of the day, even if you
have automatic oilers fitted to you supply system. If
you do not have in line oilers, put 2-3 drops of oil
into the tool first thing and then add 2 drops every
1-2 working hours.
Nailer Operation (Simplified)
The nailer is basically a double acting piston, with a
striker connected to it. When air is supplied to the
tool it is so designed as to be stable with the pis-
ton/striker in the ‘down’ position; with the porting
directing the air to the top side of the cylinder, all
vents closed. When the piston is pushed up it
changes the porting to vent the air from the top of
the cylinder, close the bottom port and to direct air
into the lower side. This drives the piston up; when
the piston reaches the top of its stroke, it changes
the porting to shut off the top vent, open the lower
vent and direct air into the top of the cylinder, this
drives the piston down, attempting to reach its
stable position. If it is unable to achieve this stable
position, because the nail is holding it off, it repeats
the cycle, and will continue to do so until the nail is
been driven deep enough to no longer exert a
destabilising force on the striker/piston.
Note. Sometimes, perhaps due to the tool being
dropped, the piston is moved to mid strike where is
neither’ twixt nor’ tween, if this happens air will
bleed through both sides of the piston and the
nailer will be unable to cycle. This can usually be
rectified by a sharp ‘slap’ on the head of the nailer
to ‘shake’ the piston one way or the other, this will
enable the nailer to achieve its stable position.
Connect the palm nailer to the hose line, check
there are no leaks anywhere in the system.
Organise a piece of scrap timber and a nail of the
size and type you wish to use. Insert the head of
the nail into the shroud of the nailer against the
striker; it will be held by the small magnetic retainer
in the wall of the shroud. Locate the point of the
nail to the timber and press down firmly.
Try to position the nailer so as to drive the nail
straight. Be prepared for the rapid hammer action,
and the slight ‘drumming’ through the hand. As the
nail is driven deeper into the timber the nailer is
‘held off’ the surface by the action of the sprung
shroud; this is to give greater control over the
depth to which you wish to drive the nail. If you
continue to press down, i.e. fully depressing the
shroud, the nailer will continue to hammer and the
depth to which the nail is driven will depend on
the size of the nail (i.e. the resistance to being
driven into the timber, length, head size, timber
type etc, ) versus the air pressure you have supplied
to the tool. Obviously, the higher the pressure the
more force will be applied to the striker, and the
deeper the nail can be driven.
Establish the best pressure etc., to give the desired
results before commencing the job proper.
