EYE PROTECTION which conforms to ANSI specifications and provides protection against
flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator
and others in the work area when connecting to air supply, loading, operating or servicing
this tool. Eye protection is required to guard against flying fasteners and debris, which
could cause severe eye injury.
The employer and/or user must ensure that proper eye protection is worn. Eye
protection equipment must conform to the requirements of the American National
Standards Institute, ANSI Z87.1 and provide both frontal and side protection. NOTE:
Non-side shielded spectacles and face shields alone do not provide adequate
protection.
TO PREVENT ACCIDENTAL INJURIES:
• Never place a hand or any other part of the body in nail discharge area of tool
while the air supply is connected.
• Never point the tool at anyone else.
• Never engage in horseplay.
• Never pull the trigger unless nose is directed at the work.
•Always handle the tool with care.
• Do not pull the trigger or depress the trip mechanism while loading the tool.
LOADING THE N79RH
1.Open the magazine:
Pull pusher back to engage
latch.
2. Load Nails:
Hold nailer down with
magazine tilted downward.
Insert sticks of nails
3. Close Magazine:
Release latch by pulling latch tab
and pusher together slightly to
disengage, slide pusher against nails.
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 is required, disconnect air supply.
3. 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.
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. The dashes on the front of the depth control are evenly spaced 08”
(2mm). Zero would have the deepest countersink and 12 may leave the nail head above the work. The tool
is shipped from the factory on setting “0”.
5.To make the adjustment, use a 10mm 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. Move the lower portion of
the depth control to the desired height and tighten the 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.
NOTE: Use only BOSTITCH nails recommended for use in Bostitch N79RH series nailers or nails
which meet the Bostitch specifications.
