Machine/ Tool Safety Instruction Sheet
Jointer Plainer


Second to circular saws, hand-feed jointers or surface planers are the most dangerous woodworking machines. Most injuries are caused by the hands and fingers of the operator coming in contact with the blades of the machine. In particular, many of these accidents occur when short lengths of stock are being used.

Pre-Operation



  • Safety glasses with side shields or safety goggles must be worn. If a face shield is worn, eye protection must be worn underneath.
    The knives of the cutter head must not extend beyond the body of the head more than 3.2 mm.

  • The cutterhead on the left side should be guarded with a spring loaded, self-closing guard that adjusts to the size of the stock. This guard should only be removed when rabbeting. Ensure the guard behind the fence is also in place.

  • Lock the fence into position before using the jointer.
    Operation

  • Use a hold-down push block whenever the wood is narrower than 7.6 cm.

  • The operator should never place hands over the front or back edges where they can easily come into contact with the head. Hands should be kept as high as possible on the side of the stock.

  • Stock that has loose knots, splits, structural defects, metal or stone in it should never be jointed.

  • Check the width, thickness and length of stock before jointing it.
    Stock less than 300 mm long should not be jointed
    Stock that is less than 20 mm high should not be edge-jointed

  • Do not face stock that is less than 12 mm thick. Always use a push block for thin material
    Allow the cutterhead to come to full speed before using the jointer.

  • Stand to one side of the machine, not directly in front of the jointer.

  • Do not leave the jointer until the cutterhead has come to a complete stop.


  • Return the depth of cut to 1 mm when you are finished with the jointer. You, or the next operator, could be seriously injured if the jointer is set for a deep cut as kickbacks occur when the depth of the cut is deep.


  • Clean up the work area

    Thickness Plainer

    Pre-Operation


  • Safety goggles or safety glasses with side shields must be worn.


  • If the planer does not have a soundproof enclosure around it, provide hearing protection for all persons that will be working in the vicinity.


  • The cutter heads of the planer should be completely enclosed with solid metal guards.


  • Ensure that these are in place prior to operation.


  • Thickness- The thickness of the lumber should be examined before you plane it. Lumber less than 10 mm can be planed by:


  • Ensure that an instructor is supervising.


  • Place the thin board on top of a thicker board (at least 19 mm thick) and
    Run both boards through the planer together.


  • Stock that is thicker at one end than the other should be planed by inserting the thicker end into the planer first.


  • Length-
    Lumber less than 50 mm longer between the distance of the infeed and the outfeed cannot be safely planed as it may jam the machine.
    Lumber that is quite long must have adequate space at the outfeed end of the planer. The planer should not be too close to a wall.
    Be careful when planing short stock. Infeed rollers will sometimes cause short stock to quickly tilt up and then down. This can cause a pinch point for fingers between the table and the stock.
    Width-Examine the width of the lumber. Most planers remove a maximum of 3 mm per pass. If a narrow piece of lumber is being planed, the maximum amount may be removed. A piece that it at the maximum width of the planer may cause the motor to overheat and the cutter to stall. If the motor does stall, follow lock out procedure (turn off the power switch) and lower the table prior to restarting the machine.
    Check the board for loose knots, nails, staples, dirt, sand or other foreign objects that could come free during the planing process, harming you or the machine.
    Lumber that does not have square ends cannot be planed as the ends can catch on the pressure bar and jam.
    Ensure that the dust removal equipment is working properly before starting the planer.
    To prevent other people from getting struck by long, fast moving boards, fence or mark off the space at the outrunning end.
    Lumber that has a varnish or finish on it should not be planed, as the dust created may be harmful to your health. Also the painted or varnished finish will quickly dull the machine's knives.
    Prior to starting the machine, lower the table and remove any wood shavings, loose knots and slivers of wood from the table and roller assembly.
    Operation
    Wear safety goggles or safety glasses with side shields.
    Stand to one side when using the planer.
    Do not allow the stock to feed through your hands when the machine self feeds. This will prevent any slivers being forced into your skin at the same rate the planer is planing the wood.
    Operators should stop and lockout the feeder rolls, cutter heads and cylinders in accordance with TRU's Lockout Procedure before placing their hands in the bed plate to remove wood fragments, to make adjustments or for any other reason.
    Wood chips and knots are frequently thrown out of the planer, therefore operators should not look into the planer to watch the operation.
    Other persons should not work or walk directly behind the feeding end of the planer. A barrier or guardrail should be used when the machine is running to prevent this from occurring.
    When removing lumber from the outfeed of the planer, never come between the end of a long plank and an immovable object such as a wall.

    Radial Arm Saw
    1. Only operators trained in the safe operation of a radial arm saw are allowed to use the saw.
    2. The operator should check the following points before operating the radial arm saw:
    3. Operator must wear safety glasses
    4. If the material chips severely, a face shield should be used in addition to safety glasses
    5. Blade should be checked for tightness
    6. Ensure the guard is in place that covers the top of the blade and the blade arbor ends
    7. Verify location of off switch and/or emergency power disconnect
    8. Ensure that the table is clear of materials, tools, and debris
    9. If the saw is used for ripping, ensure that an anti-kickback device is installed and operating properly.
    10. If the saw is used for ripping, the wood must be fed against the direction in which the saw blade turns, and the direction of the saw rotation must be clearly marked on the blade hood.
    11. If the saw is used for ripping, a permanent label at least 1-1/2 inches by 3/4 inch must be affixed to both sides of the rear of the blade hood at approximately the level of the arbor, rading as follows: DO NOT RIP FROM THIS END, or equivalent wording.
    12. The saw must have a limit chain or other positive stop to prevent the blade from traveling beyond the front of the table.
    13. The saw must have a device installed which will return the saw automatically to the back of the table when released at any point of its travel. This device must also prevent the saw from rebounding after it returns. As an alternative, the front of the table may be raised to a height that will cause the saw to return to the rear of the table without rebounding.
    14. When changing the blade or servicing the saw, the power disconnect must be locked in the "off" position. For saws with a cord and plug, the saw must be unplugged. The saw must be tested after disconnecting power and before beginning service.
