IMPORTANT NOTE (all P240, P250 & P260)
Piston ring (P-522A or P-622A) is a wear part that should last over
1,000,000 cycles (about 200,000 sq.ft.) under normal use. Dirt or
particles in the compressed air may lessen its life. Excessive wear of
the piston ring will result in occasional fasteners not set or skipped.
This can be temporarily fixed with a small length of tape between
the piston and the ring (never exceed one turn). It is recommended to
replace this part if the tool needs to be opened for servicing and has
been in use for some time. |
