Functional Description - Makita AN901 Instruction Manual

CAUTION:
Low air output of the compressor, or a long or
•
smaller diameter air hose in relation to the nailing
frequency may cause a decrease in the driving
capability of the tool.
Lubrication
To insure maximum performance, install an air set (oiler,
regulator, air filter) as close as possible to the tool.
Adjust the oiler so that one drop of oil will be provided for
every 30 nails.
Fig.2
When an air set is not used, oil the tool with pneumatic
tool oil by placing 2 (two) or 3 (three) drops into the air
fitting. This should be done before and after use. For
proper lubrication, the tool must be fired a couple of
times after pneumatic tool oil is introduced.

FUNCTIONAL DESCRIPTION

CAUTION:
Always lock the trigger and disconnect the hose
•
before adjusting or checking function on the tool.
Nose adapter
When nailing workpieces with easily-marred surfaces,
use the nose adapter. It is factory installed at the rear of
the tool.
Fig.4
Attach the nose adapter to the contact arm. When not in
use, store the nose adapter at the rear of the tool to keep
it from being lost.
Fig.5
Adjusting depth of nailing
To adjust the depth of nailing, turn the adjuster so that
the arrow above the adjuster will point to the number
indicated on the adjuster. The depth of nailing is the
deepest when the arrow points to the number 1. It will
become shallower as the arrow points to higher number.
The depth can be changed in approx. 1.0 mm
increments per graduation. If nails cannot be driven
deep enough even when the arrow points to the number
1, increase the air pressure. If nails are driven too deep
even when the arrow points to the number 9, decrease
the air pressure. Generally speaking, the tool service life
will be longer when the tool is used with lower air
pressure and the adjuster set to a lower number.

ASSEMBLY
CAUTION:
Always lock the trigger and disconnect the hose
•
before carrying out any work on the tool.
Loading nailer
Select nails suitable for your work. Depress the latch
lever and open the door and magazine cap.
Fig.7
Lift and turn the coil support plate to set it to the correct
step. When loading 90 mm long nails, use the bottom
step. When loading 65 or 75 mm long nails, use the
middle step. When loading 45 or 50 or 57 mm long nails,
use the top step. If the tool is operated with the coil
support plate set to the wrong step, poor nail feed or
malfunction of the tool may result.
Fig.8
Place the nail coil over the coil support plate. Uncoil
enough nails to reach the feed claw. Place the first nail in
the driver channel and the second nail in the feed claw.
The nail heads must be in the slot in the feeder body.
Place other uncoiled nails on feeder body. Close the
magazine cap and door after checking to see that the
nail coil is set properly in the magazine.
Fig.9
Connecting air hose
Lock the trigger. Slip the air socket of the air hose onto
the air fitting on the nailer. Be sure that the air socket
locks firmly into position when installed onto the air fitting.
A hose coupling must be installed on or near the tool in
such a way that the pressure reservoir will discharge at
the time the air supply coupling is disconnected.

OPERATION
CAUTION:
Make sure all safety systems are in working order
•
before operation.
Fig.11
Fig.12
1. To drive a nail, you may place the contact element
against the workpiece and pull the trigger, or
2. Pull the trigger first and then place the contact
element against the workpiece.
No. 1 method is for intermittent nailing, when you wish to
drive a nail carefully and very accurately.
No. 2 method is for continuous nailing.
CAUTION:
However when the tool is set to the "Intermittent
•
Nailing" mode, WITH THE TRIGGER HELD IN A
HALF-PULLED POSITION, an unexpected nailing
could occur, if contact element is allowed to
re-contact against the workpiece or the other
surface under the influence of recoil.
In order to avoid this unexpected nailing, perform
as follows;
A. Do not place the contact element against the
workpiece with excessive force.
