M. 31188 DATE OF ISSUE: 08/22 REVISION: Do not use this equipment before READING this MANUAL and UNDERSTANDING its contents. These WARNINGS are included for the health and safety of the operator and those in the immediate vicinity. Failure to read and understand these warnings can result in injury or death. Electronic files include a preface containing the same important information as in the orange cover.

PRO-SERIES BIG CLEM BULK BLAST MACHINES 1.0 Safety Alerts 1.2.1 Clemco uses safety alert signal words, based on ANSI Z535.4-2011, to alert the user of a potentially hazardous situation that may be encountered while operating this equipment. ANSI's definitions of the signal words are as follows: This is the safety alert symbol. It is used to alert you to potential physical injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.  Notice indicates information that is considered important, but not hazard-related, if not avoided, can result in property...

PRO-SERIES BIG CLEM BULK BLAST MACHINES Basic components 1.4.1.1 Key components for Pro-Series Big Clem Bulk Blast Machines are shown in Figure 1. Bulk blast machines come in three sizes: 60, 120 and 160-cuft capacity. Each size is available in a stationary, yardtowable, and highway-towable models. Highway towable models include fenders, lights and electric brakes. Pneumatic remote controls are shown in Figure 2, and electric remote controls are shown in Figure 3. 1.4.1.2 Pro-Series Big Clem blast machines are furnished with manually operated pressurization and exhaust (bleed-off) valves, 1-1/2"...

PRO-SERIES BIG CLEM BULK BLAST MACHINES Welding, grinding, or drilling on the abrasive chamber or water separator can weaken the vessel. Compressed-air pressure can cause a weakened blast machine to rupture, resulting in death or serious injury. Welding, grinding, or drilling on the vessels without a National Board R stamp voids the Clemco ASME certification. 1.4.2.2 All welding repairs to the vessel must be performed by certified welders at shops holding a National Board R Stamp. Welding performed by any welder not properly qualified per the ASME code voids the Clemco ASME certification. 1.4.2.3...

PRO-SERIES BIG CLEM BULK BLAST MACHINES 1.5.1.2 The operator manually pressurizes and depressurizes the abrasive chamber using hand-operated valves. When the manually operated exhaust (bleed-off) valve is closed and the pressurization valve is opened, air enters the abrasive chamber and automatically seals the pop-up valve, which pressurizes the chamber. Although the machine is under pressure, blasting does not begin because the normally closed (NC) abrasive metering valve shuts off abrasive flow, and the normally closed ACE Air Valve shuts off air flow. Blasting starts when the operator presses...

PRO-SERIES BIG CLEM BULK BLAST MACHINES 1.5.3 Electric pressure-hold remote controls Figure 3 Refer to Section 1.5.2 for operation of pneumatic remote controls. 1.5.3.1 The principal components of the electric remote control are shown in Figure 3, The systems include the abrasive metering valve, ACE Pneumatically-Operated Air Valve, GW Electric RLX Control Handle with abrasive cutoff (ACS) switch, 50 ft electric control cord, and interconnecting control lines. Valves may differ from those shown, but connections and operation are similar. Refer to Section 2.5 to complete electric controls and...

PRO-SERIES BIG CLEM BULK BLAST MACHINES 1.5.4 Abrasive cutoff switch (ACS) 1.5.4.1 An abrasive cutoff switch (ACS) is a standard feature of the pressure-hold remote controls. The operator uses the switch to close the abrasive valve independently of the air valve so that air without abrasive exits the nozzle. This feature is used to clear abrasive from the blast hose and to blowdown the blasted surface. • Pneumatic ACS: The ACS switch is mounted on the RLX Control Handle, as shown in Figure 2. • Electric ACS: The ACS switch is wired into the box at the back of the RLX handle, as shown in Figure...

MINIMUM ID AIR LINE RECOMMENDATIONS BASED ON THE NOZZLE SIZE AND THE NUMBER OF NOZZLES IN USE 2.2.2 CFM shown in Figures 4 is the approximate cfm required with 140 psi nozzle pressure, when the nozzle is new and when worn. A nozzle is considered worn when the orifice is 1/16" larger than its original size. Refer to Figure 5 for the cfm at other pressures. 2.2.3 Do not use fittings or adaptors that decrease the ID of the plumbing or compressed-air supply line. The compressor must provide adequate output, and the hose or plumbing between the compressor and the blast machine inlet ports must have...
