FASTENER DEPTH CONTROL ADJUSTMENT
The Fastener Depth Control Adjustment feature provides control of the nail drive depth, from flush with or
just above the work surface to shallow or deep countersink.
TO ADJUST THE FASTENER DEPTH CONTROL:
DISCONNECT TOOL FROM AIR SUPPLY BEFORE ATTEMPTING ANY
PARTS
DISASSEMBLY AND BEFORE CHANGING THE WORK CONTACTING
ELEMENT ADJUSTMENT.
1. With air pressure set, drive a few fasteners into a
representative material sample to determine if adjustment
is necessary.
2. If adjustment to the drive depth is required, measure the
difference in depth between the nail as driven in the sample
material and the desired drive. The depth control should be
changed by the same amount. To reduce the drive depth,
the work contacting element should be lengthened. To
obtain a deeper drive, the work contacting element should
be shortened.
3. If adjustment is required, disconnect air supply.
4. Note the level at which the depth control is assembled.
Decide what adjustment is required to achieve the length
change determined in (2) above.
5. To make the adjustment, use an 8mm wrench or nut driver to loosen the (2) elastic stop nuts on the
depth control approximately 2 full revolutions. It is not necessary to remove these nuts. Do not
overtighten. Check that the work contacting element operates freely without sticking or binding.
6. Reconnect air supply and drive a few fasteners in a sample of material to determine if adjustment is
correct. If further adjustment is necessary, disconnect air and repeat above.
DIRECTIONAL EXHAUST DEFLECTOR
N64C DRIVER MAINTENANCE INSTRUCTIONS
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.
Loosen screw as shown. Adjust to desired exhaust direction and tighten screw.
5/32" (4mm) maximum limit of driver recessed into piston.
Do not exceed this limit.
NOTE: Stepped face and single groove (for #103298)
5.547"-5.567"
(140.8mm-141.4mm)
