(0.79 kg)Type Circuitry: Solid State ElectronicFiring Voltage: 350 VDC Minimum (Nominal)Firing Energy: 6.125 Joules (w/s)Shunt Timing: 4.5 to 8 m/sec (Avg 6 m/sec)Power Source: 4 Ea. 1.5V Alkaline Dry Cells ('AA' Cells, NEDA 15A) Section II - Operating ProceduresTO TEST: Before connecting to blasting circuit; depress "CHARGE" switchuntil "READY" light illuminates. While maintaining pressure on "Charge"switch depress "DETONATE" switch. "READY" light should go off immediately.Caution: Do NOT relax "Charge" switch when depressing "Detonate" switch.The HBR-20P utilizes a dual switch firing mechanism to assure the blaster'sconviction to detonate.When "READY" light fails to illuminate replace the 4 'AA' AlkalineCells under battery cap on right side of machine. Observe cap position when replacing cap so as not to cross thread.TO OPERATE: Connect machine to the blasting circuit and repeat "CHARGE" and "DETONATE" sequence as in "TO TEST."Section III - Handling & CareTo maintain the proper functionality of your Scorpion HBR-20P Blasting unit please observe the following: a. Avoid severe impact. The HBR-20P is impact resistant however severe localized or blunt impact could crack and/or breach the HBR-20P's casing. NEVER USE THIS UNIT IF ITS CASE IS CRACKED OR BREACHED. In this instance please see Section V - Servicing. b. Avoid leaving the HBR-20P partially or fully submerged in water. should your HBR-20P become partially or fully submerged in water towel dry the machine including switch and binding posts. Should battery corrosion occur refer to Section V - Servicing. c. Avoid wrenching, impacting, or over-tightening binding posts. Should this happen to the binding posts the protective plastic shielding may become damaged or removed. SHOCK HAZARD: If the protective plastic shielding is removed from one or both of the binding posts potentially lethal voltage exists to a grounded blaster should contact be made with the exposed binding post at discharge. See Section V - Servicing for maintenance and repair information. d. After daily use clear debris and/or dust from in and around switch bezel and store it in a safe and dry environment. e. NEVER use your HBR-20P as a lever or impact device. f. NEVER use your HBR-20P as an alternate energy source on equipment for which it was not designed. g. Output oscillograms are recorded on every machine by the manufacturer. If you need a copy of these test traces contact E.I.T. Corporation at (570) 286-7744. For annual or biannual maintenance programs: Testing and output traces are available by the manufacturer. See Section V - Servicing for return information. h. NEVER USE A DAMAGED OR QUESTIONABLE MACHINE. For repair and servicing see Section V - Servicing.Section IV - LabelingIn accordance with MSHA regulations your HBR-20P must have a label which clearly designates it as an MSHA approved Permissible Blasting Unit when used in that capacity. Should this label become unlegible or is removed see Section V - Servicing for replacement.
