Makita AR410HR Manual De Instrucciones página 10

Suitable for use on general plasterboard with thicknesses
of 9.5mm, 12.5mm and 15mm.
Steel sheet backing up to 0.8mm thick can be worked on
(screws cannot be driven into layered steel sheet
backing).
Always use Makita genuine linked screws.
We recommend that in normal situations the driver be
used in Switching Mode (1), and set to Switching Mode
(2) when screws cannot be driven for lack of power.
ASSEMBLY
Loading Screws
CAUTION:
• Always disconnect air hose from main unit before
loading screws.
• If the main unit is operated by mistake, it may lead to
personal injury.
1. Disconnect air hose.
2. Press down lever while opening door. (Fig. 9)
3. Open magazine cap. (Fig. 10)
4. Load screws into magazine.
5. Pull out lead screw as far as driver guide and then
close magazine cap.
6. Completely load lead screw into screw channel. At this
point, check to see that screw is completely set in
feeding claw.At this time, if the screw cannot be set
because the bit has come down as far as the driver
guide, turn the main unit upside down (driver guide is
on top), and return the bit to its designated position.
7. Slowly close door until lever stops fully. (Fig. 11)
OPERATION
How to Drive Screws
CAUTION:
• The utilized air pressure must be between 1.76 and
2.26 MPa. Do not repeatedly drive screw(s) in on top of
a screw that has been already driven in.
• This driver is not an impact gun, so it requires a
reasonable amount of pressing.
• If the main unit is not pressed sufficiently, the screw
may not drive in flush to workpiece, or come out.
• Always press the end of the discharge nose at a right
angle onto the workpiece and then drive in screw. We
recommend that you use the intermitent-drive action to
ensure proper screw driving. (Fig. 12 & 13)
First, lightly press the end of the contact arm onto a
workpiece.
Next, pull the trigger.Here, do not release the trigger until
the motor stops running.Note that if the trigger is released
too soon, the screw may not be driven in flush to
workpiece, and/or the screw feed may be impaired.
Switching between intermitent drive and
continuous drive
Intermitent Drive Method (Fig. 14 & 15)
Intermitent drive is where the contact arm is pressed
against a workpiece, and the trigger pulled to drive in one
screw.
Set the switching lever to the
"Intermitent Drive Mode".

position to set driver to
(1) Press contact arm against workpiece.
(2) Pull trigger.
Continuous Drive Method (Fig. 16 & 17)
Continuous drive is where the contact arm is repeatedly
pressed onto different areas of workpiece while the trigger
is held down to continuously drive in screws.
Set the switching lever to the
"Continuos Drive Mode".
(1) Pull trigger.
(2) With the trigger held down, each time the contact
arm is pressed against the workpiece, a screw
will be driven in continuously.
Trigger Locking Method
This driver has a trigger lock to prevent accidents due to
mistaken operation when main unit is not being used.
The trigger lock is a mechanism that locks the trigger,
preventing discharge of screws.
Set the switching lever to the
"Trigger Lock".
When drive screws, set lock lever to the
position. When not using the driver, always lock the
trigger and disconnect the air hose.
How to Cut linked Sheet (Fig. 18)
CAUTION:
• When cutting linked sheet, always lock trigger, and
disconnect air hose.
When using linked screws, the linked sheet protrudes
from the driver guide. Tear away the protruding linked
sheet in the direction of the arrow.
MAINTENANCE
CAUTION:
• Always disconnect the air hose from the tool before
attempting to perform inspection or maintenance.
How to Rectify Screw Jam
CAUTION:
• When rectifying screw jam, always lock trigger, and
disconnect air hose. (Fig. 19)
Lock trigger and disconnect air hose.
Open door, and pull out linked screws.
Insert thin metal bar into discharge nose, and hit it with a
hammer. In some cases, this metal bar will become stuck
when hit. Note, that at such times, the bit must not be hit,
as the bit end may be damaged, and lead to impaired
screw driving. (Fig. 20)
Remove screw(s) jammed inside driver guide using minus
screwdriver or other such tool.
After removing screw(s), make sure bit is not protruding
into screw channel (if it is, press it out of the way using the
metal bar).
After removing the jammed screw(s), reload the driver
with screws.
How to Replace Bit
CAUTION:
• When replacing bit, always lock trigger, disconnect air
hose, and remove all loaded screws.
Take care not to lose small components.
