Functional Description; Adjusting Depth Of Nailing - Makita AF500HP Instruction Manual

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. Nails may be driven accidentally if the safety
mechanism is not working correctly.
SAVE THESE INSTRUCTIONS.
INSTALLATION
Selecting compressor (Fig. 2)
• Select a compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation between nailing frequency,
applicable pressure and compressor air output. Thus,
for example, if nailing takes place at a rate of
approximately 60 times per minute at a compression of
1.76 MPa (17.6 bar), a compressor with an air output
over 40 L/min is required. Pressure regulators must be
used to limit air pressure to the rated pressure of the
tool where air supply pressure exceeds the tool's rated
pressure. Failure to do so may result in serious injury to
tool operator or persons in the vicinity.
Selecting air hose
WARNING:
• Use a high pressure resistant air hose. The air
pressure used for this nailer is higher than that for other
general finishing nailers. (Fig. 3)
• Use an air hose as large and as short as possible to
assure continuous, efficient nailing operation.
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 (Fig. 4)
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
50 nails.
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. 5)

FUNCTIONAL DESCRIPTION

CAUTION:
• Always lock the trigger and disconnect the hose before
adjusting or checking function on the tool.
Checking before operation
WARNING:
• Never use the nailer when the safety elements are not
in working order. Using it in that condition may cause a
personal injuries and damage.
This nailer does not fire nails without activating both the
trigger and the safety elements. Before nailing, check the
nailer that the safety systems is in working order by
following the procedure shown below. (Fig. 6)
1. Make sure that nails are not loaded on the tool before
operation.
2. Connect the air hose to the tool.
3. Set the lock lever in the released position.
4. Pull the slide door of the magazine toward yourself.
5. Pull only the trigger.
6. Release the finger from trigger and place the safety
element against the workpiece.
7. Bring the safety element off the workpiece, pull the
trigger and then place the safety element against the
workpiece.
8. If the nailer works between 5 - 7, the safety elements
are not in working order. (Fig. 7 & 8)
Using the trigger lock
The tool has trigger lock to avoid accidents by an
unintentional start. The trigger lock makes the trigger
unmovable and let the tool cause no firing.
To lock the trigger, set the lock lever in the "LOCK
position.
Before nailing, set the lock lever in the "FREE
position. When not in use, always set it in the "LOCK
position and disconnect the hose from the tool. (Fig. 9 &
10)

Adjusting depth of nailing

CAUTION:
• Always lock the trigger and disconnect the hose before
adjusting the depth of nailing. (Fig. 11 & 12)
To adjust the depth of nailing, turn the adjuster. The depth
of nailing is the deepest when the adjuster is turned fully
in the A direction shown in the figure. It will become
shallower as the adjuster is turned in the B direction.
Hook (Fig. 13)
CAUTION:
• Always lock the trigger and disconnect the hose before
changing the hook installation position and using the
hook.
• Never hook the tool at high location, on waist belt or
potentially unstable surface.
The hook is convenient for hanging the tool temporarily.
The hook can be installed on either side of the tool.
When changing the installation position, remove the
screw from the hook. Place the hook on the desired
position and secure it with screw.
ASSEMBLY
CAUTION:
• Always lock the trigger and disconnect the hose before
carrying out any work on the tool.
• Load the same kind, size and uniform length of nails
when loading nails in the magazine.
