1.4 Components and General Description
1.4.1 Components of a standard system are shown in
Figure 1. They include the inlet valve, piston or diaphragm
outlet valve (the piston valve is used in most applications,
the diaphragm valve is recommended for use with fine
mesh or aggressive abrasive), abrasive trap, RLX control
handle, 55 ft and 5 ft long twinline control hoses, two
control hose unions, and an 18" interconnecting hose.
1.4.2 Additional parts used with optional ACS cutoff
systems are shown in Figure 2. ACS systems include a 50
ft single-line hose, 18" long interconnecting hose, an RLX
control handle with ACS air switch assembly, and a
pneumatically operated metering valve. The metering
valve supplied with the system may differ from that shown.

1.4.3 A remote control system is an OSHA-required
safety device; it is required when an operator mans the
nozzle. The control handle, located near the blast
nozzle, is the activator of the remote control system.
When the operator intentionally or unintentionally
removes handheld pressure from the control handle,
the machine depressurizes and blasting stops. The
remote control system "fails to safe", which means if an
interruption in the control-air circuit occurs, for any
reason, the remote control deactivates the blast
machine and blasting stops.
Additional parts used with optional
ACS cutoff system.
Figure 2
W
ARNING
Never modify or substitute remote control
parts. Parts from other manufacturers are not
compatible with Clemco equipment. If ANY part
of the remote control system is altered,
involuntary activation can occur, causing
serious injury.
1.5 Theory of Operation
1.5.1 TLR-100 and TLR-300 remote controls are
pressure-release-style systems, which control the
pressurization and depressurization of the blast
machine. Pressurization, which starts blasting, occurs
when the operator presses the control handle, and
depressurization, which stops blasting, occurs when the
operator releases pressure on the control handle.
1.5.2 Clemco remote controls operate pneumatically
on a return-air principle (Refer to Figure 1). When
compressed air is supplied to the machine, control air
travels from the orifice fitting, down the outbound
twinline (shown shaded in Figure 1) and escapes
through an opening located under the control lever. As
long as the control lever remains up, air escapes
through the opening, and the normally closed inlet valve
remains closed and the normally open outlet valve
remains open (no blasting). When the control lever is
pressed, a rubber button seals the opening, forcing air
from the outbound side of twinline to return through the
inbound side. Pressure in the return line opens the inlet
valve and closes the outlet valve. This action
pressurizes the blast machine and begins the blasting
process. Releasing the handle exhausts the control air,
closing the inlet valve, and opening the outlet valve to
depressurize the blast machine and stop the blasting.
1.6 Abrasive Cutoff (ACS) Option
1.6.1 The abrasive cutoff switch is mounted on the
control handle. It closes the metering valve so that air
alone, without abrasive, exits the nozzle. This feature is
used to clear the blast hose and to blowdown the blast
surface. Refer to Section 3.4 for operation of the optional
ACS.
NOTE: The ACS feature requires a pneumatically
operated abrasive metering valve. It is not available
on Lo-Pot blast machines, which do not have
adequate clearance for the metering valve.
1.7 Electric Control Option
1.7.1 Electric remote controls (electro-pneumatic) are
recommended when the nozzle and remote control
handle are farther than 100 feet from the blast machine.
Pressure loss through pneumatic systems over longer
distances delays actuation time and could prevent fast,
safe depressurization time should an accident or an
emergency occur. For additional information contact

www.clemcoindustries.com, or email
[email protected].

2.0 INSTALLATION
W
ARNING
Failure to observe the following procedure
before performing any service on a blast
machine or pneumatic accessories can cause
serious injury or death from the sudden release
of trapped compressed air:
1. Empty the blast machine of abrasive.
2. Depressurize the blast machine.
3. Lockout and tagout the compressed-air
supply.
4. Bleed the air-supply line to the blast machine.
Installation Note: To prevent thread galling and to
provide an airtight seal, use thread sealant on all
male NPT (pipe) threads.
2.1 Install Valves onto Blast Machine
2.1.1 Empty the blast machine of abrasive.
Depressurize the machine. Shut down the compressed-
air source. Bleed the air-supply line. Lockout and tagout
the air supply. Disconnect the air-supply line.
2.1.2 Remove the existing inlet valve and outlet valve
from the machine. The machine should resemble the
illustration in Figure 3. We recommend installing outlet
piping, as shown in the illustration.
Figure 3
2.1.3 Install the inlet valve and abrasive trap, as
shown in Figure 4. The directional arrow on the inlet
valve points toward the blast machine, indicating the
direction of air flow. The arrow on the abrasive trap
points away from the machine.
Figure 4
2.1.4 Install the piston or diaphragm outlet valve and
muffler, as shown in Figure 5.
Figure 5
W
ARNING
Clemco supplies an exhaust muffler with all blast
machines of 2-cuft capacity and larger. The
muffler reduces exhaust noise and prevents
abrasive from exhausting upward or sideways
into the air. When the blast machine is
depressurized, the muffler body will pop up to
diffuse the air and abrasive. When the machine
is fully depressurized, the muffler body will drop,
permitting trapped abrasive to empty. For the
muffler to work properly, it must be installed with
the body facing up, as shown in Figure 5.
If an application requires the muffler to be
removed, the exhaust piping must be plumbed to
direct exhausting air in a direction that ensures
no persons will be exposed to possible injury
from high-velocity air and media that escapes
when the blast machine depressurizes.

2.2 Set Up for Multiple Blast Machines Operating
From a Common Compressed-Air Supply
2.2.1 Where multiple blast machines are operating
from a single air source, install a ball cone check valve
at the air supply on each machine. Refer to the
illustration in Figure 7 to install a check valve on a blast
machine.
2.2.2 If the machines are positioned close together use
a receiver tank or manifold and run separate air lines to
each machine. The check valves may be located on the
receiver tank outlets if the air line goes directly to the blast
machine and nowhere else.
CAUTION
If multiple machines are operating from a
common compressed-air supply, and a
machine is under pressure when another
machine is pressurized, the sudden, increased
demand for air can reverse air flow from the
machine that is under pressure and
contaminate the compressed-air supply with
abrasive-laden air. Install check valves at the
piping inlet to prevent the reversal of air.
NOTE: Do not use a swing check valve, as the swing
gate may break in blast machine applications. When
installing the valve, make sure the directional arrow
is pointing in the direction of the air flow (toward the
machine).
Figure 7
2.2.3 Use a Clemco ball cone check valve noted
below to reduce pressure drop through the valve. A
smaller-size valve could restrict air movement and
reduce nozzle pressure.
 TLR-100 with 1" NPT inlet valve
Use 1-1/4" NPT check valve ....... Stock No. 02088
 TLR-300 with 1-1/2" NPT inlet valve
Use 1-1/2" NPT check valve ....... Stock No. 02296
2.3 Prepare Blast Hose and Control Hose
Connections
NOTE: Control hoses come with reusable hose
ends. Excess hose may be cut-to-fit and recoupled,
as explained in Section 5.5.
W
ARNING
Where two or more blast machines are used in
close proximity, care must be taken when
tracing and connecting control lines and blast
hose. Cross-connecting control hose or blast
hose can lead to serious injury, death, or
property damage from unintentional actuation
of a blast machine. To prevent cross-
connecting blast hose and control hose, the
hoses should be of equal lengths and the hoses
and blast machine couplings clearly marked.
Use optional hose identification kits, stock no.
15890 for use with two blast machines, or stock
no. 15891 for up to four machines. Mark each
hose and corresponding connection, per the
instructions supplied with the kit, and carefully
trace and verify each connection before
operating.

Moist air that freezes can cause blockage at the
control handle or in the control lines. Blockage
can cause involuntary activation of the remote
controls or prevent the controls from
deactivating upon release of the control handle.
This situation can result in serious injury or
death. If remote controls are operated in
freezing or near-freezing weather, install a
Clemco Anti-Freeze Injector, stock no. 05537,
on the remote control air-supply line.
2.3.1 Uncoil the blast hose and lay the 50 ft twinline
hose alongside it.
2.3.2 Band the control handle to the blast hose close
to the nozzle holder, as shown in Figure 8, using the two
nylon ties provided. After the control is firmly attached,
clip the tie ends to avoid snags or interference with the
operation of the control handle.
Figure 8
2.3.3 Attach the 50 ft twinline hose to the two fittings
on the control handle, as shown in Figure 9. Either side
of the hose can be attached to either fitting. When using
the ACS option, attach the single-line hose noted in
Section 2.4.1.
Figure 9
NOTE: When attaching Clemco twinline hose to a
Clemco inlet valve or control handle, either side of
the twinline hose can be attached to either twinline
fitting on the valves.
2.3.4 Working backward from the control handle,
band the twinline hose to the blast hose every four to six
feet and as close to the couplings as possible. NOTE:
When using the optional ACS feature, band all hoses
after the single ACS hose is attached to the RLX.
2.3.5 Temporarily connect the blast hose to the quick
coupling on the blast machine, as shown in Figure 10.
Figure 10
2.3.6 Attach the 5 ft twinline control hose to the inlet
valve, as shown in Figure 10; one side of the hose
connects to the unused upper elbow, the other side to
the orifice fitting. NOTE: When using a pressure
regulator to reduce blast pressure below 60 psi (80
psi when using a pneumatically operated abrasive
metering valve), relocate the orifice upstream of the
regulator, as shown in the insert in Figure 1, and plug
the orifice port in the inlet valve. Doing so provides
full line-pressure to the pneumatic control circuit.
2.3.7 Connect the two hose unions to the other end of
the 5 ft hose and place the ends next to the blast-hose
coupling.
2.3.8 Band the 5 ft twinline control hose, on the blast
machine side of the unions, to the quick-coupling nipple.

2.3.10 Make sure that all fittings are tight. Leaks cause
the system to malfunction.
NOTE: When removing the blast hose from the
machine, disconnect the 50 ft twinline hose (and
optional ACS hose) at the unions.
When attaching the blast hose, make sure all twinline
fittings are tight. Make sure coupling gaskets are in
place and in good condition before connecting the blast
hose to the blast machine. Use safety lock pins or safety
wire to lock the couplings together and prevent
accidental separation while under pressure, and use
safety cables to prevent hose from whipping should
separation occur. Safety cables and lock pins are listed
in Section 7.1

3.0 OPERATION
W
ARNING
Refer to the manuals listed in paragraph 1.1.2.
Do not operate this equipment before reading
the instruction manuals for all equipment.
3.1 Startup
3.1.1 Connect the air supply to the blast machine
inlet. The compressor should be located upwind from
the blasting operation to prevent dust from entering the
compressor intake.
3.1.2 Make sure that the safety petcock located on the
inlet valve is open to prevent unintentional blasting. The
petcock is open when the petcock lever is in-line with
the petcock, as shown in Figure 14.
Figure 14
W
ARNING
To prevent severe injury from accidental
activation of the blast machine, open the safety
petcock when the blast machine is not in use.
Opening the petcock prevents unintentional
blasting. The control handle will not activate the
machine when the petcock is open.
3.1.3 Make sure the control-handle lever is in the up (no
blast) position, and that the lever and safety lock move
freely.
W
ARNING
A separate manual is supplied with the RLX
remote control handle. Do not operate the
machine before first reading the manual for the
control handle.
3.1.4 Check to make sure that the control lever will
not seal the opening on lever unless the safety lever-
lock is pulled down.
W
ARNING
A malfunctioning control handle can cause
unintentional actuation of a blast machine or
prevent a machine from deactivating upon
release. A malfunctioning control handle must
be taken out of service immediately and
repaired or replaced. Serious injury or death
can result from unintentional blasting.
3.1.5 Start the compressor, and bring it up to
operating temperature and pressure. The pressure must
be more than 50 pounds per square inch (psi) but must
not exceed the blast machine’s rated pressure.
3.1.6 Fill the machine with screened, clean, dry
abrasive that is specifically manufactured for abrasive
blasting. NOTE: Use only abrasives specifically
manufactured for blasting that are compatible with
the surface being blasted. Abrasives produced for
other applications may be inconsistent in size and
shape and produce an unsatisfactory finish, contain
particles that could jam the abrasive metering valve,
or cause irregular wear.
3.1.7 Slowly open the compressor air-supply valve to
pressurize the air-supply line. Listen for noise that
indicates any open lines or leaks.
3.1.8 Do not allow anyone around the blast machine
except the blast operator or machine tenders, who are
appropriately attired in approved personal protective
equipment, as noted in Section 3.2.
3.1.9 When the blast operator is ready, either the
operator or the machine tender stands away from the
concave filling head of the blast machine and the exhaust
muffler, and then closes the safety petcock. Closing the
petcock prepares the machine for remote operation and
activation by the control handle. Air should be heard
escaping from the orifice under the control lever but
nowhere else. The air escaping at the handle is an audible
signal that means air is supplied to the blast machine,
and it will activate when the control handle is pressed.
3.2 Blasting Attire
3.2.1 Operators and anyone else exposed to the
hazards generated by the blasting process must wear
appropriate protective gear, including abrasive-resistant
clothing, leather gloves, eye and hearing protection, and
a NIOSH-approved, Type CE supplied-air respirator.
3.2.2 Don protective blasting attire outside the blast
area in a clean nonhazardous environment, free of
contaminants, where the air is safe to breathe.

All dust is hazardous to breath. Before blasting,
test the coating and substrate for toxic materials,
such as lead or other heavy metals, or asbestos.
These hazards require special measures to
protect the operators and the environment.
Obtain a safety data sheet (SDS) for the blast
abrasive to identify hazardous substances. Silica
sand (crystalline) can cause silicosis, lung
cancer, and breathing problems in exposed
workers. Slag abrasives may contain trace
amounts of toxic metals such as arsenic,
beryllium, and cadmium. Any abrasive dust has
potential to cause lung disease.
Abrasive blasting operations can create high
levels of harmful dust and noise. No dust is
safe to breathe. Failure to wear NIOSH-approved
respirators can result in serious lung disease or
death. The respirators must be properly fitted
and maintained. Use only NIOSH-approved, Type
CE supplied-air respirators approved for
abrasive blasting.
Loud noise generated by the use of
compressed air can cause hearing damage.
Everyone in the blasting area must wear
approved hearing protection.
During abrasive blasting, abrasive and dust
particles in the area around the blast machine and
blast nozzle become airborne. Everyone working
in the vicinity of abrasive blasting must wear
properly maintained, NIOSH-approved, respiratory
protection, eye protection, and hearing protection,
appropriate for the job site hazards.
It is the employer’s responsibility to train
employees to identify hazardous substances
and to provide suitable policies, procedures,
monitoring, recordkeeping, and personal
protective equipment.
3.2.3 When finished blasting and after cleanup is
completed, remove the respirator and protective clothing
outside the respirator-use area in a clean environment
where the air is safe to breathe.
3.3 Pressurize Blast Machine to Start Blasting
3.3.1 Don all protective blasting attire, per Section 3.2.
3.3.2 When the blast operator is ready to blast, the
operator or the machine tender must close the safety
petcock. Closing the petcock prepares the machine for
remote operation and activation by the control handle.
Air should be heard escaping from the opening under
the control lever but from nowhere else. The air
escaping at the control handle is an audible signal
meaning air is supplied to the blast machine, which will
activate when the control handle is pressed.
3.3.3 Hold the blast hose securely and point the
nozzle only toward objects intended to be blasted.
3.3.4 Fold down the safety lever-lock and press the
remote control handle, as shown in Figure 15. Within a
few seconds the pop-up valve will automatically close,
and the blast machine will pressurize to start blasting.
WARNING
Be prepared for the recoil from the blast hose.
Blasting should begin within a few seconds
after pressing the control lever.

WARNING
OSHA requires the use of remote controls on all
blast machines when an operator controls the
nozzle. To comply with OSHA regulations, the
remote control handle, which starts and stops
the flow of air and abrasive, must be held down
manually. Never tie down the control-handle
lever or attempt to bypass any part of the remote
control system. Doing so will defeat the purpose
of the fail-to-safe feature of the remote control.
Serious injury or death can result from
uncontrolled blasting. Ref. 29 CFR 1910.244 (b).
Control Lever (locked up)
Fold down lever lock.
Press control lever
down to begin blasting.
