ENGLISH

Use an air hose as large and as short as possible to 

assure continuous, eficient stapling operation.
With an air pressure of 0.49 MPa (4.9 bar), an air hose 

with an internal diameter of over 6.5 mm and a length 
of less than 20 m is recommended when the interval 
between each stapling is 0.5 seconds.
Air supply hoses shall have a minimum working pres-
sure rating of 1.03 MPa (10.3 bar) or 150 percent of the 
maximum pressure produced in the system whichever 
is higher.

Lubrication

To insure maximum performance, install an air set (oiler, 

regulator, air ilter) as close as possible to the tool. 

Adjust the oiler so that one drop of oil will be provided 

for every 50 staples.

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 

itting. This should be done before and after use.

 

For proper lubrication, the tool must be ired a couple of 

times after pneumatic tool oil is introduced.

DESCRIPTION

CAUTION:

 

Before adjusting or checking 

function on the tool, always return the trigger and 
disconnect the air hose from the tool.

 Adjuster

To adjust the depth of stapling, turn the adjuster.

The depth of stapling is the deepest when the adjuster 

is turned fully in the A direction shown in the igure. It will 

become shallower as the adjuster is turned in the B direction.

If staples cannot be driven deep enough even when the 

adjuster is turned fully in the A direction, increase the 

air pressure.

If staples 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 staple driving.

Hook

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 stapler accidentally drops, it may 

result in misiring and personal injuries.

 Hook

The hook is convenient for hanging the tool temporarily.
