FUNCTIONAL
DESCRIPTION
CAUTION:
Before adjusting or checking func-
tion on the tool, always release the trigger and
disconnect the air hose from the tool.
Adjusting depth of nailing
CAUTION:
Always release the trigger and
disconnect the hose before adjusting the depth
of nailing.
► Fig.5: 1. Adjuster
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.
If nails cannot be driven deep enough even when the
adjuster is turned fully in the A direction, increase the
air pressure.
If nails are driven too deep even when the adjuster is
turned fully in the B direction, 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 deeper depth of nail driving.
Hook
CAUTION:
Always release the trigger and
disconnect the hose before changing the hook
position.
CAUTION:
Never hook the tool at high loca-
tion or on potentially unstable surface.
CAUTION:
Do not hang the hook from the
waist belt. If the nailer accidentally drops, it may
result in misfiring and personal injuries.
► Fig.6
► Fig.7: 1. Hook 2. Hex socket bolt 3. Hole
The hook is convenient for hanging the tool temporarily.
To change the hook position, remove the hex socket
bolt and switch the hook direction. The hook has two
holes. Choose the hole depending on your preferable
hook width.
Adjusting the shingle guide
► Fig.8: 1. Contact element 2. Shingle guide
3. Shingle
► Fig.9: 1. Adjusting plate 2. Lever
The shingle guide is designed for consistent shingle
exposure.
Place shingle in desired position. Turn the lever to
release the adjusting plate. Set the nailer so that the
contact element will depress both the exposed shingle
and previous row of the shingle. Slide the adjusting
plate up against the bottom of the exposed shingle and
return the lever to lock the adjusting plate.
ASSEMBLY
CAUTION:
Before carrying out any work on
the tool, always release the trigger and discon-
nect the air hose from the tool.
CAUTION:
Load the same type, size and
uniform length of nails when loading nails in the
magazine.
Loading nailer
NOTICE:
Select nails suitable for your work.
NOTICE:
Set the coil support plate according to
the nail size to be used. 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.
1. Depress the latch lever and open the magazine
cap.
► Fig.10: 1. Magazine cap 2. Latch lever
2. Lift and turn the coil support plate so that the
arrow with nail size indicated on the coil support plate
will point to the corresponding graduation increment
marked on the magazine.
► Fig.11: 1. Coil support plate 2. Graduation 3. Arrow
3. 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. Place other uncoiled nails on feeder body.
Close the magazine cap after checking to see that the
nail coil is set properly in the magazine.
► Fig.12: 1. Feed Claw
Connecting air hose
CAUTION:
Do not rest your finger on the
trigger when connecting the air hose.
► Fig.13: 1. Air fitting 2. Air socket
Slip the air socket of the air hose onto the air fitting on
the tool. 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.
