Woodworking Machinery General Requirements checklist
The professional inspection solution
You can conduct this checklist for free on the Checkbuster platform. You can use a lap-top, PC or the free inspection App
General Machine Construction
- Each machine is constructed and installed so it is free from sensible vibration when the largest tool is mounted and run at full speed.
- Arbors and mandrels are constructed to have firm and secure bearing and be free from play.
- Saw frames on tables are constructed with lugs cast on the frame or with equivalent means to limit the size of the saw blade that can be mounted.
- Circular saw fences are constructed so they can be firmly secured to the table without changing their alignment with the saw.
- Circular saw gauges are constructed so they slide in grooves or tracts that are securely machined, to ensure exact alignment with the saw for all positions on the guide.
- Hinged table saws are constructed so that the table can be firmly secured in any position and in true alignment with the saw.
- All belts, pulleys, gears, shafts, and moving parts are guarded.
- Each woodworking machine is provided with a disconnect switch that can be locked in the off position.
- The frames of all exposed noncurrent-carrying metal parts are grounded.
- If the possibility exists of contacting part of a circular saw either beneath or behind the table, that part is covered with either an exhaust hood or guard.
- Revolving double arbor saws are fully guarded.
- The placement and mounting of saws, cutter heads, or tool collars on machine arbors are accomplished when the tool has been accurately machined to size and shape to fit the arbor.
- Combs (featherboards) or suitable jigs are provided at the shop or lab for use when a standard guard cannot be used, as in dadoing, grooving, joining, moulding, and rabbetting.
- The operating speed is etched or otherwise permanently marked on all circular saws over 20 inches in diameter and operating at over 10,000 peripheral feet per minute.
- Woodworking tools and machinery do meet the American National Standards Institute (ANSI) codes for safety.
Machine Controls and Equipment
- Mechanical or electrical power controls are provided on each machine to make it possible for the operator to cut off the power without leaving his or her operating position.
- On machines driven by belts and shaftings, a locking-type belt shifter or equivalent positive device is used.
- Each operating treadle is protected against unexpected tripping.
- Automatic feeding devices are installed on machines whenever the nature of the work permits.
- Feeder attachments do have the feed rolls or other moving parts covered or guarded to protect the operator from hazardous points.
Inspection and Maintenance of Woodworking Machinery
- Dull, badly set, improperly filed, or improperly tensioned saws are immediately removed from service before they cause the material to stick, jam, or kickback when it is fed to the saw at normal speed.
- Saws with adhered gum are cleaned immediately.
- All knives and cutting heads of woodworking machines are kept sharp, properly adjusted, and firmly secured.
- All bearings are well lubricated and kept free from lost motion.
- Arbors of circular saws are free from play.
- Sharpening or tensioning of saw blades or cutters is done only by people with demonstrated skill in this kind of work.
- Cleanliness is maintained around woodworking machinery so guards function properly and fire hazards are prevented in switch enclosures, bearings, and motors.
- All cracked saws are immediately removed from service.
- Inserting wedges between the saw disk and the collar to form what is commonly known as a wobble saw is prohibited.
- Push sticks or blocks are provided at workplaces in several sizes and types suitable for the work to be done.
