Risk Assessment - Wood Planers

This risk assessment is intended to provide guidance on the risk associated with the above equipment and activities in normal use. Please also check general risk assessments for the space as a whole. Any discrepancies, errors or concerns should be raised with the document maintainers or trustees - do not edit this assessment directly. For responsible persons and last update, see 'version log' of the assessment page.

Activity

Use of handheld or stationary wood planing equipment such as handheld planers, bench planers (aka jointers) or thickness planers

Signage

Understanding Risk Rating

LOW - Ensure current control measures are in place and continue with activity

MED - Control measures may be adequate, co-supervision is recommended

HIGH - Do not undertake activity without further consultation with area specialists

Risk Assessment

Identify Hazards Who May be Harmed and How Severity Control Measures Likelihood Risk Rating
Incompetent user User, bystander HIGH Members must not use tools that they are not competent to use. Members must challenge use that they believe is dangerous. Members must read the user manual for this tool. Members must read the risk assessment before using a tool. Members will be advised during induction which tools they will need supervision or an induction to use. Only authorised members will complete maintenance and calibration tasks. LOW MED
Contact with rotary knives User HIGH Do not put hands within 10cm of blade. Do not push workpiece over blade with hands. Use a push block to push workpiece over cutting area. Use guard to cover unused cutting area. Use guard to cover entire cutting area when thicknesser is being used. Do not insert hands into thicknesser when machine is plugged in. Planer should be turned off immediately after use. MEDIUM MED
Drawing in (being pulled into the drum) User HIGH User of the thicknesser/planer should not wear gloves, ties, scarves, or other long flowy clothing that could get pulled into the blade. Do not move hands past the blade. Do not use the machine on short stock. LOW MED
Dust (inhalation, fire, explosion) User, bystander MEDIUM Stationary machines must be used with the workshop dust extractor. An extraction hose must be attached to the machine’s extraction hood, which must be positioned appropriately for use with the thicknesser or planer. Maintenance must include the cleaning of dust from within the unit housing where accessible. Check the extraction hood periodically for blockages. A respirator or mask should be used whilst operating this tool for prolonged periods. LOW LOW
Noise User, bystander MEDIUM Ear protection is advised. LOW LOW
Flying splinters User, bystander HIGH Eye protection must be worn In the workshop. Only cut wood, ensuring the workpiece is free from nails, screws or other objects. LOW MED
Lifting heavy object User MEDIUM The machine must be lifted into a stable position on the working area using correct manual handling procedures. LOW LOW
Electrocution User, bystander HIGH Do not use if any damage to plug, cables, or machine. LOW MED

What are the Planers For

Generating smooth flat surfaces on a piece of timber Reducing the thickness of timber to a specific size

Demonstrate the 4-step process to surfacing a board:

  1. Plane one wide face on the surface planer
  2. Plane one edge on the surface planer, 90° to the first
  3. Thickness plane the other face to dimension, parallel to the first
  4. Square the other edge parallel to the other edge. Best to use the table saw for this, use thickness planer if > tablesaw capacity

Just can jump it at any page of this procedure depending on how flat and how smooth you need to be (e.g. if one face already good can go straight to the thicknesser)

Alternatives:

  • Handheld planer for big stuff
  • Handplanes for small stuff, also often get a better finish

Surface Planer

Parts of the Machine

Point Out:

  • The blade
  • The infeed and outfeed tables
  • The infeed table height adjustment
  • The fence
  • The guard - vertical and horizontal adjustments

Pre-inspection

Check blades are not damaged or chipped. If doing anything critical, run a test piece through.

If blades are damaged it's a nightmare job to change - speak to the maintainers

If edge planing, always a good idea to check the squareness of the fence.


Face Planing

  1. Check material is suitable - length > 300mm, at least 10mm thick, no loose knots or shakes
  2. Set guard to the appropriate width (width of material + ~5mm)
  3. If material is very wide, more than about 100mm, switch to bridge guard mode
  4. Have paddles at the ready
  5. Set depth of cut (generally don't start more than 1mm, can dial it up if needed)
  6. Turn on and run up to speed. Gently move work forward over the bed, keeping good down pressure throughout
  7. Keep pressure consistent over the whole length of the cut

Edge Planing with the Fence

  1. Generally the same procedure as face planning, but use hand pressure (generally not paddles) to keep the wood pressed against the fence as well as down on the bed and forwards (a three-way push)
  2. Never pass hands directly over the blade, pass-through motion

Thickness Planer

Generally a safer machine as the blades are enclosed, but that doesn't mean inherently safe Minimum length (300mm) very important. Side runners can be glued on if piece is short

  1. Set depth (just enough for workpiece to slide under grey tray)
  2. Pass wood through. First few cuts won't do anything till you find the depth
  3. Keep cutting. Generally 1/2 turns of the handle is a happy feed rate
  4. Stop when you reach depth. The scale is a useful guide but not accurate, best to measure

After Use

  1. Sweep down the bed and the surrounding bench
  2. Hoover inside the machines if they've been run without extraction.
