Makita Construction Coil Nailer AN621 Instruction Manual page 18

Check regularly to see if there is sufficient pneumatic
oil in the oiler of the air set. Failure to maintain suffi-
cient lubrication will cause O-rings to wear quickly.
Keep the air hose away from heat (over 6OoC, over
14OOF), away from chemicals (thinner, strong acids or
alkalis). Also, route the hose away from obstacles
which it may become dangerously caught
on
during
operation. Hoses must also
be
directed away
from
sharp edges and areas which may lead to damage
or abrasion to the hose.
T o maintain product SAFETY and RELIABILITY, maintenance and repairs should be performed by Makita
Authorized or Factory Service Centers, always using Makita replacement parts.
