Functional Description - Makita AT638A Manual De Instrucciones

Use an air hose as large and as short as possible to
assure continuous, efficient stapling operation.
With an air pressure of 0.49 MPa (70 PSIG), an air hose
with an internal diameter of over 6.5 mm (1/4") and a
length of less than 20 m (6.6 ft.) 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 (150 PSIG) or 150 percent of
the maximum pressure produced in the system which-
ever is higher.
Lubrication
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 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
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.

Adjusting depth of stapling
► 1. 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 figure. 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.
