45. DO’S AND DON'TS
DO NOT CONNECT HANDIMASTER BLOCKS CLOSER THAN 10CM TO EACH OTHER.
CLIP THE HANDIMASTER BLOCK 90° TO THE TUBING TO ENSURE PROPER CONTACT.
DAISY CHAIN TIMING NOT RECOMMENDED.

46. DO’S AND DON'TS
DO NOT LET THE BURNING PART OF A FUSE TOUCH THE TUBING AS IT WILL MELT IT AND WILL CAUSE MISFIRES/CUT-OFF’S.
DO NOT INSERT MORE THAN THE MAXIMUM RECOMMENDED NUMBER OF TUBES IN A HANDIMASTER™ BLOCK.

47. DO’S AND DON'TS
ALWAYS USE SUFFICIENT LENGTHS OF SHOCK TUBE FOR THE SPECIFIC APPLICATION.
ALWAYS INITIATE SHOCK TUBE BY USING A DETONATOR (NONEL‡ FUSE MASTERSTARTER®) OR DETONATING CORD.

48. DO’S AND DON'TS DO NOT REVERSE PRIME WITH SHOCK TUBES.
DO NOT USE THE DETONATOR TO MAKE A HOLE INTO A CARTRIDGE EXPLOSIVE FOR PRIMING PURPOSES.
DO NOT TRY AN PULL OUT A MISFIRED UNIT OUT OF CHARGED HOLE.
