Additional Safety Instructions for Jointers

JOINTER KICKBACK. "Kickback" is when the workpiece is thrown off the jointer table by the force of the cutterhead. Always use push blocks and safety glasses to reduce the likelihood of injury from “kickback.” If you do not understand what kickback is, or how it occurs, DO NOT oper- ate this machine!

OUTFEED TABLE ALIGNMENT. Keep the top surface of the outfeed table parallel and even with the knives at top dead center (the highest point during rotation) to reduce the risk of kickback and personal injuries.

PUSH BLOCKS. Always use push blocks when using this machine. Never pass your hands direct- ly over the cutterhead without a push block.

WORKPIECE SUPPORT. Adequately support- ing the workpiece at all times while cutting is critical for making safe cuts and avoiding injury. Never attempt to make a cut with an unstable workpiece.

USING GOOD STOCK. Jointing safety begins with your lumber. Inspect your stock carefully before you feed it over the cutterhead. Never joint a board that has loose knots, nails, or staples. If you have any doubts about the stability or struc- tural integrity of your stock, DO NOT joint it!

KICKBACK ZONE. The "kickback zone" is the path that is in line with the tables. Never stand or allow others to stand in this area during opera- tion.

MAXIMUM CUTTING DEPTH. The maximum cutting depth for one pass is 5⁄16". Never attempt any single cut deeper!

JOINTING WITH THE GRAIN. Jointing against the grain or jointing end grain is dangerous and could produce chatter or excessive chip out. Always joint with the grain.

GUARDS IN PLACE. All operations must be per- formed with the cutterhead guard in place.

PROPER CUTTING. When cutting, always keep the workpiece moving toward the outfeed table until the workpiece has passed completely over the cutterhead. Never back the work toward the infeed table.

SAFE KNIFE PROJECTION. Knives should never be set in the cutterhead so they project more than 1⁄8" (0.125") from the cutterhead body. Knives that project from the cutterhead too far may come loose during operation, may become damaged, or may damage the cutterhead.

Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to decrease the risk of operator injury. If normal safety pre- cautions are overlooked or ignored, serious personal injury may occur.

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious per- sonal injury, damage to equipment, or poor work results.
