Used for Cutting wood or plastics
Model Number Elu 3401 or DeWalt 738
Serial Number 000322


We have a bandsaw in the workshop. This is used for making long straight cuts in sheet material, like acrylic or plywood. Please don't use it unless you've had a safety briefing - it is very easy to accidentally injure yourself with it.

The bandsaw will fill up with dust internally over time, so please open the case and hoover out inside periodically.

Inserts

The bandsaw has a replaceable wooden insert in the table. If this is too loose, wobbles, is chipped, or has an excessively large hole, it may need replacing. There are spares in the blades box, but if they have all been used, you will need to make more.

  1. Obtain some 6mm ply. Cut into 50x50mm squares.
  2. Smooth the edges on the sander, to remove the rough parts. If the blanks are slightly too wide, correct this now.
  3. Round the corners of the blanks - the disc sander is good for this. This does not need to be perfect, but needs to be done or they will not fit.
  4. Set the fence to be in line with the edge of the slot, and with the old insert in, make a cut until the new insert aligns with the old. Do not cut the blank in two.
  5. Place the spare ones in the container in the blades box. (It is significantly easier to make lots at once)

Safety

  • Wear eye protection - hot debris in the eye is not pleasant
  • Wear ear protection - this equipment is loud, and use without hearing protection can cause or exacerbate hearing loss.
  • Do NOT wear gloves, unless specifically sauitable for this equipment - gloves will provide no protection against a bandsaw unless specifically reinforced.

Guide to the risk matrix points system

Hazard severity Points rating Definition
Nil 1 Very minor injury, bruise, graze, no risk of disease.
Slight 2 Minor injury, which would allow the individual to continue work after first aid treatment on site or at a local surgery. The duration of the stoppage or treatment is such that the normal flow of work is not seriously interrupted.
Moderate 3 Temporary disability causing injury or disease capable of keeping an individual off work for three days or more and reportable under RIDDOR
High 4 Causing death, serious injury or permanent disability to an individual.
Very high 5 Causing multiple deaths and widespread destruction eg. fire, building collapse.
Hazard probability Points Rating Definition
Remote possibility 1 There is really no risk present. Only under freak conditions could there be any possibility of an accident or illness. All reasonable precautions have been taken - This should be the normal state of the workplace.
Unlikely 2 This incident or illness might occur but the probability is low and the risk minimal.
Possible 3 The accident may occur if additional factors precipitate it, but it is unlikely to happen without them.
Highly likely 4 Will happen more often than not. Additional factors could precipitate an incident but it is still likely to happen without this additional factor.
Inevitable 5 If the work continues as it is, there is almost 100% certainty that an accident will happen, for example:

• A broken stair or broken rung on a ladder • Bare, exposed electrical conductors • Unstable stacks of heavy boxes

Risk Rating Definitions
Score Definition Action
1 to 4 Low No action required
5 to 9 Moderate Reduce risks if reasonably practicable
10 to 15 High Risk Priority action to be undertaken
16 to 25 Unacceptable Action must be taken IMMEDIATELY
