TLR-50 PNEUMATIC REMOTE CONTROLS

3.3 Start
Blasting
WARNING
When approaching an idle blast machine, and
before loading the blast machine with abrasive,
always check to make sure the safety petcock
is open. This step is especially important if one
worker (a machine tender) loads the machine
with abrasive while another worker (the blast
operator) controls the blasting. The blast
operator could pressurize the machine before
the machine tender has moved away from the
machine. During pressurization abrasive could
be forced out of the top of the machine, and
cause injury.
3.3.1
Hold the blast hose securely and point the
nozzle only at objects intended to be blast cleaned.
3.3.2
Pull back the safety lever lock and depress the
remote control handle. Within a few seconds the pop-up
valve will automatically pop up and the blast machine
will pressurize to start blasting.
WARNING
OSHA requires the use of remote controls on all
blast machines. To comply with OSHA
regulations, the remote control handle which
starts and stops the flow of air and abrasive,
must be held down manually. Do not 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).
4.0 PREVENTIVE
MAINTENANCE
NOTE: These preventive maintenance instructions
pertain to the remote controls only. Read the owners
manuals for the blast machine and all blast accessories,
for inspection and maintenance schedules of that
equipment.
3.4 Stop
Blasting
4.1 Daily
3.4.1
To stop blasting, release the control handle. The
outlet valve will open and the blast machine will
depressurize. The pop-up valve automatically drops
when air is expelled from the machine and pressure
equalizes.
4.1.1
With the air off, before beginning blasting,
inspect the following:
•
Inspect the RLX Control Handle; look for the
following:
3.4.2
When the control handle lever is released, the
safety lever lock will flip up to lock the handle lever in the
up (open) position.
•
The lever must not seal the opening on the
control unless the safety lever lock is pulled down.
•
The
handle lever
must return to the "up"
position when released.
3.4.3
Make sure that the control handle safety lever
lock is up, and that it prevents the handle lever from
engaging.
•
The
safety lever lock
must return to the "up"
position when the handle lever is released.
•
Both the handle lever and safety lever lock must
move freely with no drag or binding.
3.4.4
Always open the safety petcock during work
breaks and before filling the blast machine. Opening the
petcock prevents unintentional blasting.
WARNING
Malfunctioning control handles could cause
unintentional actuation of a blast machine, or
prevent a machine from deactivating upon
release. Malfunctioning control handles must
be taken out of service immediately and
repaired or replaced. Serious injury or death
could result from unintentional blasting.
