Operating Instructions (continued)
Quick Release Nose
Refer to Figure 5 (page 6).
The Sears 18 Cruage Brad Nailer is equipped with a quick
release nose for clearing jammed nails.
* Ira nail jams in the tool, disconnect the air supply from the
too!. Open the magazine and remove any nails. Pull the
nose cover latch (Key No. 37) down and release the nose
cover. Remove the jammed nail and secure the latch,
Reload the nails and connect the air supply.
Operating Pressure
• Use only enough air pressure to perform the nailing opera-
tion. Air pressure in excess of that which is required will
make the nailing operation inefficient and may cause pre-
mature wear or damage to the tool.
.. Determine minimum air pressure required by driving some
re,stnails into the workpiece. Set air pressure so that test
nails heads are driven down flush with the work. Nails dri-
ven too deep may damage workpiece.
Exhaust Deflector
Refer to Figures 4 & 5 (pages 4 and 6).
* The position of the exhaust deflector can be changed to
direct exhaust as desired. Exhaust deflector can be posi-
tioned at the left, front or right side of lOOt. Reposition
deflector (Key No. 6) by carefully removing four bolts
(Key No. 4) and rotating deflector to desired position.
• Be sure not to _nlsplace valve spring (Key No. 7). Secure
four bolts making sure that valve spring and exhaust plate
are properly positioned.
