N88 DRIVER MAINTENANCE INSTRUCTIONS
Worn driver causing poor quality or loss of power:
-Wear on the driving tip will affect the nail drive, giving symptoms of bent and incompletely driven
nails, and damaged nail heads.
-The driver length may be adjusted to allow the driving tip to be redressed to compensate for wear.
Heat and precise measurement are required. Contact a qualified service technician for
this adjustment.
-The length setting for a new driver is shown below. Measurement is from the bottom face of
the main piston.
-Note that the measurement from the top of the piston gives the maximum amount the driver may be
adjusted to allow redressing. Always extend the driver the minimum required to allow redressing to
restore the driving end; several redressings will be possible before this maximum depth is reached.
