Installation; Functional Description - Makita AR410HR Instruction Manual

• Perform cleaning and maintenance right after finishing
the job. Keep the tool in tip-top condition. Lubricate
moving parts to prevent rusting and minimize friction-
related wear. Wipe off all dust from the parts.
• Do not modify tool without authorization from Makita.
• Ask Makita's Authorized service centers for periodical
inspection of the tool.
• To maintain product SAFETY and RELIABILITY,
maintenance and repairs should be performed by
Makita Authorized Service Centers, always using
Makita replacement parts.
• Use only pneumatic tool oil specified in this manual.
• Never connect tool to compressed air line where the
maximum allowable pressure of tool cannot be
exceeded by 10%. Make sure that the pressure
supplied by the compressed air system does not
exceed the maximum allowable pressure of the
fastener driving tool. Set the air pressure initially to the
lower value of the recommended allowable pressure.
• Do not attempt to keep the trigger contact element
depressed with tape or wire. Death or serious injury
may occur.
• Always check contact element as instructed in this
manual. Screws may be driven accidentally if the safety
mechanism is not working correctly.
SAVE THESE INSTRUCTIONS.

INSTALLATION

Selecting air hose (Fig. 2)
Use a high pressure resistant air hose.
Use an air hose as large and as short as possible to
assure continuous, efficient screw-driving operation.
CAUTION:
• Low air output of the compressor, or a long or smaller
diameter air hose in relation to the screw-driving
frequency may cause a decrease in the driving
capability of the tool.
Lubrication (Fig. 3)
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 screws.

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. (Fig. 4)

FUNCTIONAL DESCRIPTION

CAUTION:
• When adjusting driving depth, always lock the trigger
and disconnect the air hose.
Adjuster (drive depth adjuster) Operating
Method (Fig. 5 & 6)
CAUTION:
• When adjusting driving depth, always lock the trigger
and disconnect the air hose.
This driver is equipped with an adjuster for adjusting
screw driving depth.
Turn the adjuster to adjust driving depth. Driving
adjustment range is 6mm. (one turn of adjuster adjusts
depth by approximately 0.8mm.)
Hook (Fig. 7)
CAUTION:
• When using the hook, or changing its position, always
lock the trigger, and disconnect the air hose.Do not
fasten hook onto waist belt, etc.
• If hook becomes unfastened and the driver drops,
driver may operate by mistake, and lead to injury.
The hook is useful for hanging up the driver temporarily.
The mounting position of the hook on the driver can be
changed.
Remove the hook mounting screw, change position of
hook, and re-secure screw.
Switcher Mode Selection (Fig. 8)
This driver is equipped with a switcher to enable selection
of mode for optimum driving according to the material of
the workpiece. Set to mode positions shown in "Switching
Mode Chart" below for optimum use. Thoroughly turn the
knob until it clicks to a halt properly at either position (1) or
(2). If the driver is used with the switcher in a position
between (1) and (2), driver components may become
damaged, and/or normal performance not achieved.
