If stock stops feeding: If the board being planed stops feeding, disengage or turn the feed off and turn the power off. Wait until the cutterhead comes to a complete stop before lowering the table to remove the board. NEVER lower the table with the power on and the stock still in the machine, as a kickback can occur.
Hand safety. Keep hands outside the machine. NEVER reach under the guards to try to clear stock that stops feeding. Do not clear chips and sawdust with hands; use a brush. Do not have any part of the hands under that part of the board that is over the table when starting a cut; the infeed roll will engage the board and force it down against the table causing a pinching action.
Cutterhead rotation: Be sure cutterhead rotates under power in a counterclockwise direction when viewed from the main drive motor side.
Material condition: Do not plane boards with loose knots or with nails or any foreign material on its surface. Knife impact on these objects can cause the knives to be pulled out and cause them to shatter against the chipbreaker or pressure bar. Twisted, warped, or wind in stock should first be jointed on one surface before attempting to plane a parallel surface on the planer. Serious stock flaws cannot be removed by use of a planer alone.
Machine capacity: Do not make any cuts requiring more power than is available on the machine. Do not attempt to feed two boards side by side (multiple board surfacing) on any machine not equipped with sectionalized infeed roll and chipbreaker. NOTE: The 22" Planer is rated at 7.5 horsepower with maximum cutterhead speed of 4800 RPM. DO NOT equip your planer with a motor of higher horsepower or run the cutterhead in excess of 4800 RPM. Doing so voids the warranty and Powermatic holds itself harmless from any injury that may result.
Machine adjustments: Make all machine adjustments with power off except feed rate.
Job completion. If the operator leaves the machine area for any reason, the planer should be turned "off" and the cutterhead should come to a complete stop before his departure. In addition, if the operation is complete, he should clean the planer and the work area. NEVER clean the planer with power "on" and never use the hands to clear sawdust and debris; use a brush. Disconnect machine from power source before cleaning.
Replacement parts. Use only Powermatic or factory authorized replacement parts and accessories; otherwise the warranty and guarantee is null and void.
Misuse. Do not use this Powermatic planer 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.
If you are not thoroughly familiar with the operation of planers, obtain advice from your supervisor, instructor or other qualified person.
Drugs, alcohol, medication. Do not operate this machine 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
*Crystalline silica from bricks and cement and other masonry products.
*Arsenic and chromium from
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
