Replace/ repair guards as necessary
2 / Install/replace abrasive disc / a) Accidental start-up of Disc Sander--b) Bodily injury and/or damage to abrasive disc due to incorrect installation--c) Hand/finger contusion due to tool slippage from installing/adjusting abrasive disc--d) Hand/finger abrasion from abrasive disc / a) Disconnect Disc Sander from its power source and ensure motor switch is off--b) Install an abrasive disc that is the correct size and RPM rating--c) Use correct tool for installing/adjusting abrasive disc. Wear recommended gloves.--d) Wear recommended gloves when handling abrasive disc.
3 / Adjust work rest / a) Incorrect spacing between work rest and abrasive disc causing bodily injury and/or damage to workpiece--b) Hand/finger contusion due to tool slippage from adjusting work rest / a) Work rest spacing should be calibrated to <1/8th (0.125) inches from face of abrasive disc. Ensure work rest is secured to support workpiece.--b) Use correct tool for adjusting work rest. Wear recommended gloves.
4 / Transport workpiece to Disc Sander / a) Hand/finger laceration from edges of workpiece--b) Strain/sprain from heavy and/or awkward workpiece--c) Slip/trip/fall in area around Disc Sander--d) Foot injury from dropping workpiece / a) Wear recommended gloves when handling workpiece--b) Use mechanical lifting device or get assistance from co-worker--c) Clean/clear work area/surfaces of unused tools/material.

Use a jig or holding device to sand small workpieces. Avoid awkward operations and hand positions where a sudden slip could cause hands/fingers to move into abrasive disc. Wear recommended gloves.--b) Use safety eyewear and/or face shield--c) Use local exhaust ventilation and/or wear recommended respiratory protection--d) Tie hair back. Do not wear loose clothing or jewellery while ope---rating Disc Sander--e) Wear recommended hearing protection--f) Feed workpiece slowly into abrasive disc. Do not apply too much pressure against abrasive disc when machining workpiece--g) Ensure work rest spacing is properly calibrated and secure--h) Sand workpiece on the side of abrasive disc spinning in the downward direction
7 / Conclude sanding / a) Hand/finger abrasion from removing debris near abrasive disc--b) Contact burn from workpiece becoming hot--c) Leaving disc sander power on / a) Push machine stop button and wait for abrasive disc to stop before removing debris. Use a stick or brush to remove debris.--b) Wear recommended gloves and avoid handling workpiece by machined end--c) Do not leave Disc Sander running unattended.
