INSTRUCTIONS

1. Always read the instructions.
   

2. Always wear safety glasses.
   

3. Unscrew oil cap and fill with Cengar Green Oil. Replace cap.
   

4. Isolate air supply before fitting blade by pushing stop button in.
   

5. Fit the blade with the teeth facing the machine. Avoid handling the blade teeth.
   

6. Secure blade by tightening both grip screws with supplied T key.
   

7. Connect to 5-6 bar air supply and pull out stop button.
   

8. Ensure nosepiece is pressed against work piece to be cut.
   

9. Press trigger and apply light downward pressure.
   

DO’S & DON’TS

1. ALWAYS use Cengar green oil for best results. Keeping the saw clean and well oiled will give excellent reliability, and a long life.

2. ALWAYS use Cengar Bi-Metal Shatterproof blades, for safety, and best cutting performance.

3. ALWAYS isolate the air supply when changing blades.

4. ALWAYS wear eye protection when using saws.

5. ALWAYS keep the nosepiece hard against the work piece to prevent excessive vibration.

6. ALWAYS isolate the machine when not in use.

7. ALWAYS keep others away from the saw blade to prevent injury or trapping.

8. ALWAYS have machines vibration tested annually to ensure exposure is kept to the minimum.

9. NEVER fit breakable “All-Hard” blades in Cengar saws, these can shatter causing injury to the operator and others.

10. NEVER operate saw without wearing safety glasses.

11. NEVER operate saw whilst you, or others are near the saw blade, which can cause serious injury or trapping.

12. NEVER use excessive force because this may increase vibration above safe levels.

13. NEVER hold the Cengar saw in a vice by the body. This will distort the bores, rendering the tool inoperative.

14. NEVER screw nameplates to the body, as the screws may penetrate an airway or bore.

15. NEVER operate the Cengar saw without lubrication.

16. NEVER be tempted to clean internal parts with anything other than a clean lint free cloth or Cengar Green oil.

17. NEVER modify Cengar saws or use non Cengar parts. This will invalidate ATEX approval and warranty.
