magnets for 5/8”-7/8” diameter hole saws and 3/8” diam-   

 

eter magnets for 1 1/8” to 1 3/4” diameter hole saws. Do    

 

not use magnets on hole saws larger than 1 3/4” diameter.  

 

Return to step 7.

A.   Loosen the Gland Nut and remove the shaft.

 

B.   Clean and Grease the shaft and bearing surface of the  

  Main 

Body.

 

C.   Store the shaft and main body in the provided case to   

  prevent 

damage 

2.   Gland Repacking Instructions:
 

A.   Disassemble the packing gland and slide the shaft    

 

 

out of the Main Body.  

 

B.   Remove the old packing. 

 

C.   Replace the shaft in the Main Body with a gentle  

 

  twisting 

motion.

NOTE:

 The 

slow speed setting

 on 

the drill motor is recommended to 

prevent magnets from coming loose 

and losing the coupon. 

Do not use 

magnets

 on hole saws larger than 

1 3/4”.

End of wire on coupon retaining bit 

must extend past end of hole saw.

Tips:

•  Use a new hole saw. Time saved with the new, sharp hole saw  

  will be worth the small cost.

•  Use low RPM with larger diameter hole saws for less wear on  

  the hole saws as less heat is generated
