General Operating Procedure



Note: The following procedure is intended as a guide only.

CAUTION - USE OF THIS MACHINE REQUIRES THAT THE OPERATOR HAS BEEN TRAINED IN BLASTING TECHNIQUES.

WARNING: BATTERIES ALONE CAN FIRE ELECTRIC DETONATORS. KEEP BATTERIES AWAY FROM THE BLASTING CIRCUITS.

WARNING: NEVER CONNECT THE BLASTING CIRCUIT TO THE BLASTING MACHINE UNTIL YOU ARE READY TO FIRE THE BLAST.

1. Perform the Operational Test (battery charge, condenser and push button conditions) prior to bringing the blasting machine into the blast area.

2. Obtain electric detonator firing recommendations from the detonator manufacturer. Check the blasting circuit calculations prior to connecting to the Blasting Machine.

3. Connect the detonator wires to the lead lines using series or other circuits recommended by the detonator manufacturer.
CAUTION: Keep the lead lines shunted during wiring of the electric detonators.

4. MAKE SURE THAT ALL PERSONNEL HAVE BEEN REMOVED TO A SAFE LOCATION. 5.
Check the electric detonator circuit continuity and resistance (including the lead lines) using an approved Blaster's Ohmmeter.

5. Shunt the lead lines after checking the circuits until the blast is ready to be fired.

6. Remove the shunted lead lines connection and connect the wires to the terminals on the blasting machine. KEEP HANDS AND BODY CLEAR OF
CONDUCTORS. CONTACT WITH ELECTRICAL CONDUCTORS COULD CAUSE SERIOUS INJURY OR DEATH.

7. Depress the CHARGE push button and hold it down. The READY TO FIRE indicator lights when the capacitor reaches the design voltage.

Design Voltage
Electric Detonators
200 V
300 V
500 V
20 no
50 no
100 no

8. When the READY TO FIRE indicator lights and design voltage depress the CHARGE pushbutton, wait at least 2 seconds, then firmly depress the FIRE push buttons, continue holding both switches down until the firing operation is complete.

IMPORTANT: If the Blasting Machine should fail to fire, release both switches, disconnect and shunt the lead lines, notify personnel of blast delay and consult this manual.

IMPORTANT: The READY TO FIRE indicator does not indicate energy and therefore cannot indicate if the blasting machine has sufficient energy
output to detonate the electric detonators. Output energy must be determined as discussed in the Operational Test.

9. After the firing operation is complete, wait 5 seconds then release both switches.

10. Disconnect and shunt the lead lines.

11. Press the discharge button firmly until the condenser charge neutralize, indicator’s light does not appear after completing the process

12. Secure the machine.

Battery Recharge
Only use design power pack to recharge the battery, connect the power pack pin to the socket and charge the battery about 2 hours continuously. 

CAUTION: DO NOT CHANGE THE POWER PACK REGULAR VOLTAGE (7.5V). INCORRECT VOLTAGE WILL DAMAGE THE BATTERY 
    
Battery Replacement
Remove the bottom cover to gain access to the battery. The Blasting Machines each require one 1.5 volt Alkaline batteries, Eveready or equal. After battery replacement, replace the bottom cover. Do not use a carbon-zinc type battery as it does not have the amperage capacity to operate the Blasting Machine.

CAUTION: OBSERVE POLARITY WHEN REPLACING THE BATTERY. INCORRECT POLARITY WILL DAMAGE THE BLASTING MACHINE.

CAUTION: WHEN REPLACING THE BATTERY, USE A NEW BATTERY. DO NOT USE A PARTIALLY USED BATTERY AS IT MAY LEAK CHEMICALS CAUSING SEVERE DAMAGE TO THE BLASTING MACHINE.

CAUTION: REMOVE THE BATTERY AND EXAMINE IT FOR CHEMICAL LEAKAGE AT LEAST EVERY ONE MONTH. 

WARNING: DO NOT OPERATE THE BLASTING MACHINE IF THE BATTERY COVER IS NOT IN PLACE.

DO NOT OPERATE THE BLASTING MACHINE WITHOUT THE BOTTOM COVER IN PLACE.

WARNING: USE ONLY AN ALKALINE TYPE BATTERY.
