1. Introduction

Radial arm saws are used for rapid docking of timber to size. The machine is capable of producing noise levels in excess of 100 dB(A). This can rapidly cause hearing loss if the ears are unprotected. Good hearing protection must be worn.

2. Maintenance

  • Ensure blades are sharpened at regular intervals or as required.
  • The machine should be in good operational condition. Periodically have it inspected for bearing wear (particularly in brush type motors) and brush and armature wear. It is false economy to let the machine wear to such an extent that it becomes unserviceable.
  • On some models, the blade housings become loose and rattle. This should be secured.

3. Noise control

  • Use quiet blades
  • Rubber mounting pads under the machine will help to prevent vibration transmission through wooden floors etc.
  • Place acoustic absorption behind and around the machine in order to reduce the noise hazard radius.
  • Locate machine away from quiet work areas, alongside other noisy equipment, or in an isolated machine room. 

4. Operator control

  • Use gentle pressure and allow the blade more time to cut. This also extends blade life. 

5. Alternatives

  • Use alternative methods, eg band saws, combination saws.
