- Before operating the equipment, read, understand and follow the manufacturer's operating manual and safety decals on the equipment.
- Set up the machine on level, stable ground that is not slippery.
- Chock wheels to ensure the machine will not move during operation.
- Before start-up, ensure that there is no debris in the feed chute and that the machine is in good operating condition (e.g., check sharpness of cutting edges, tightness of bolts, condition and tension of belts).
- Ensure all guards and shields are in place, and are properly maintained.
- Check tightness of grinder teeth lock bolts daily.
- Barricade area around equipment when in use and ensure that bystanders will not be hit with flying chips or debris.
- Wear appropriate safety glasses/goggles or face shield (with safety glasses or goggles), hearing, eye, and head protection.
- Remove rings, bracelets and other jewellery (so they don't fall in or get caught in machine). Tie back long hair. Do not wear loose fitting clothing or anything that might get caught in rotating or moving parts.
- Make sure the discharge chute is positioned so the material will not hit anyone.
- Ensure there are no materials like wire, stones or glass bottles, etc. in the wood material being shredded or chipped.
- Do not feed raked-up material; it could contain stones or other material that could damage the equipment or result in injuries to the worker.
- Feed material butt-end (i.e., larger end) first.
- Do not feed short pieces by hand; place shorter pieces on top of longer pieces when feeding the machine.
- Recheck the sharpness of the knives and anvil if it becomes more difficult to feed the machine.
- Do not force material into the feeder – injuries could occur if a worker slipped and fell toward the feeder.
- Shut down equipment and wait for all moving parts to come to a complete stop before removing clogged materials or making adjustments. Prevent accidental start-up or operation by removing key or locking out controls and disengaging clutch.
- Never reach into any part of an operating machine.
- Never sit, climb or stand on any part of the chipper when it is running.
- Never reach over or work near rotating parts (entanglement happens too quickly to react).
