Powermatic PJ1696 - Manual (Page 5)

Always use a hold-down or push block when surfacing stock less than 12" inches long, or 3 inches wide, or
3 inches thick.
Do not perform jointing operations on material shorter than 8", narrower than 3/4" or less than 1/4" thick.
Depth of cut. Do not make cuts deeper than 3/4" when rabbeting. On other cuts such as edging, surfacing,
etc., depth of cut should not be over 1/16" to avoid overloading the machine and to minimize chance of
kickback.
Avoid tip-in. Never apply pressure to stock directly over the cutterhead. This may result in the stock tipping
into the cutterhead along with the operator's fingers. Follow the 3 inch rule. Position hands away from
extreme ends of stock, and push through with a smooth, even motion. Never back workpiece toward the
infeed table.
Avoid Kickback. "Pull-out" and the danger of kicked back stock can occur when the work piece has knots,
holes, or foreign materials such as nails. It can also occur when the stock is fed against the grain on the
jointer. The grain must run in the same direction you are cutting. Before attempting to joint, or plane, each
work piece must be carefully examined for stock condition and grain orientation.
NOTE: At certain times it may be necessary to plane against the grain when working with a swirl grain wood
or burls. With this type work the operator must use a lesser depth of cut and a slow rate of feed.
Hand safety. It is good practice to move the hands in
an alternate motion from back to front as the work
continues through the cut. Never pass the hands
directly over the cutter knife. As one hand approaches
the knives remove it from the stock in an arc motion
and place it back on the stock in a position beyond
the cutter knife (Figure 2).
NOTE: At all times hold the stock firmly.
Misuse. Do not use this jointer for other than its
intended use. If used for other purposes, Powermatic
disclaims any real or implied warranty and holds itself
harmless for any injury or damage which may result
from that use. Do not equip or use this jointer with a
motor larger than 7-1/2 Horsepower at 5,200 R.P.M. Use of a larger horsepower motor or higher cutterhead
speed voids the warranty and Powermatic holds itself harmless for any injury which may result.
If you are not thoroughly familiar with the operation of jointers, obtain advice from your supervisor, instructor
or other qualified person.
Drugs, alcohol, medication. Do not operate tool while under the influence of drugs, alcohol, or any
medication.
Health hazards. Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
* Lead from lead-based paint.
* Crystalline silica from bricks and cement and other masonry products.
* Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment, such
as those dust masks that are specifically designed to filter out microscopic particles.
