Refer to drawing for basic single chamber blast machine components. Review all
appropriate ewners manuals prior to installing accessory items on any Mod-U-Blast
equipment. To insure safe and efficient operation use genuine Mod-U-Blast parts and
accessories.
3.2 OSHA REQUIREMENTS: Avoid serious or fatal injury. OSHA regulations must be
followed on all blast cleaning operations, including but not limited to, Section 1910.134
(Respiratory Protection), Section 1910.244(b) (Abrasive Blast Nozzles, Remote Control
Devices), Section 1910.94 (Ventilation).
WARNING
AVOID SERIOUS OR FATAL INJURY!!!
OSHA REGULATIONS REQUIRE A (SHUT-OFF OR DEADMAN) REMOTE CONTROL
SYSTEM BE USED ON ALL ABRASIVE BLAST MACHINES. NEVER OPERATE,
RENT OR SELL AN ABRASIVE BLAST CLEANING MACHINE WITHOUT
OPERATIONAL REMOTE CONTROLS.
3.3 REMOTE CONTROL SYSTEMS: All Mod-U-Blast vessels are furnished with an
operational remote control system attached to the unit when shipped from the factory.
Pneumatic and electro pneumatic control systems are available.
The pneumatic remote control systems are “deadman” or “shut-off” controls which
operate as a double line pneumatic circuit. The system consists of a pneumatic remote
control switch connected to a dual air control line from the control valve. The system is
activated when the operator depresses the switch handle (with safety button in). When
in this position, the handle seals off the orifice directly below it and the control air flows
back into the return line section of the dual line to open the air control valve inlet and
close the control valve outlet. Compressed air seals the pop up valve against the seat
gasket and pressurizes the blast vessel. Blasting then begins.
The electric remote control systems are “deadman” or “shut-off” controls which operate
®
5
as an electrically actuated pneumatic circuit. These systems can be 12 or 120 volt
solenoids.
Safety features are incorporated into the pneumatic and electric remote control systems
to prevent accidental activation of the blast flow. Do not modify, delete, or over-ride
components of the system. Such action may cause the system to malfunction. Care
must be taken to avoid accidents. Read and abide by all warning decals, danger decals
and owner’s manual instructions before operating the blast machine.
WARNING
It is YOUR RESPONSIBILITY to read and understand all owner’s manuals, instructions,
literature, labels, specifications, and warnings either sent with or affixed to the product.
Additional precautions may be necessary, depending on attachments used and
conditions at the work site.
The manufacturer has no direct control over abrasive blast cleaning machine
application, operation, inspection, or maintenance. Therefore, it is YOUR
RESPONSIBILITY to use good safety precautions in these areas.
IMPORTANT: If you do not have a Mod-U-Blast owner’s manual(s) for your particular
Mod-U-Blast abrasive blast cleaning machine and related components, get a
replacement manual(s) from your employer, equipment dealer, rental business or ModU-Blast Mfg. Keep this owner’s manual(s) with your abrasive blast cleaning machine

6. PREVENTIVE MAINTENANCE
Regularly scheduled maintenance is the responsibility of the equipment owner
and user. Prior to each work shift the blast machine and all related components must be
inspected for worn or damaged parts. Immediately replace all worn and/or damaged
components with genuine Mod-U-Blast parts prior to using the equipment.
6.1
REMOTE CONTROL SYSTEMS. The Mod-U-Blast remote control systems are
designed to operate trouble free if the following maintenance procedures are
observed:
6.2
On a daily basis, clean the outlet silencer after four hours of blasting. Worn or
clogged outlet silencers must be replaced to prevent a malfunction or damage to
the control valve.
6.3
On a monthly basis, disassemble the control valve and check the component
parts for wear and or damage.
®
12
6.4
Refer to the Mod-U-Blast remote control switch assembly for switch
maintenance.
WARNING:
DO NOT WELD ON THE BLAST MACHINE. THIS VOIDS
NATIONAL BOARD APPROVAL AND CERTIFICATION
7. TROUBLE SHOOTING
Note: Prior to correcting any system malfunction personnel are required to wear
protective safety equipment, including but not limited to, a NIOSH approved
supplied air respirator, leather gloves, ear protection, safety shoes, and abrasive
resistant cover wear.
Observe all OSHA regulations, EPA guidelines, NIOSH local regulations and
ACGIH recommendations. Never perform service or maintenance on a blast
machine which is under pressure. Serious injury or death can occur.
7.1
No abrasive discharge from nozzle Depressurize the blast machine, blast hose
and air supply hose. SHUT OFF THE SOURCE OF COMPRESSED AIR. Make
sure the source of compressed air is a clean dry source. Inspect the nozzle,
abrasive grit valve and blast hose for blockages. Be sure that the remote control
system is operating correctly. Check the supply of abrasive in the machine. If the
problem still persists, open the abrasive grit valve to the full open position.
Secure control of the blast hose and pressurize the blast machine and quickly
open and close the choke valve.
7.2
Abrasive flow from the nozzle is spitting or slow This condition is often
corrected with a simple adjustment of the abrasive grit valve. If this does not
resolve the problem, follow the same steps as in 8.1. If the problem still persists,
excess moisture within the blast machine system will often cause an unsteady
stream of abrasive from the blast nozzle. If moisture is detected, equip the blast
machine with a moisture separator or more preferably an air dryer skid.
7.3
Blast machine tank fails to pressurize Review the start up procedures covered
in this manual. Inspect the remote control hoses or wires for leaks, kinks, or
severed connections. Be sure that the remote control system is operating
correctly. Check the volume of air supplied to the blast machine. An insufficient
air supply will not seat the pop-up valve against the filler port gasket to pressurize
the blast machine.
7.4
Remote control system failure Review the set-up procedures in this manual.
Since there are a number of reasons for this problem to occur, if the problem still
persists, contact your local Mod-U-Blast distributor or Mod-U-Blast direct 1800-661-3842.
