VACUUM RELIEF VALVE SAFETY — CONTINUED

Operating the Remote-Operated
Vacuum Relief Valve

The remote-operated vacuum relief valve is controlled by
the pendant remote control or by the front control panel.
The operation and testing instructions of this section
apply to all relief valve controls.

• A safety person who is in full sight of the operator(s)

must be used. The safety person must hold the
pendant remote for the relief valve. Never allow
workers at the end of the hose to operate the system
without the safety person in position.

• Before cleaning the suction tubes or hoses, lower the

engine speed to idle, open the relief valve, turn off
the truck’s engine, remove the keys, and lock the cab
doors.

• When working close to the end of the hose, wear

tight-fitting clothes. Keep shirts and jackets closed so
that they will not be pulled into the end of hose.

• Remove loose-fitting jewelry such as bracelets and

necklaces unless they are under tight-fitting clothing.

• Do not use hands or feet to remove obstructions from

the end of the hose.

• Keep all body extremities and clothing away from the

end of the hose.

WARNING

• For pendant remote control:

• Insert the pendant cord into the socket located

at the front control panel or the curbside control
panel.

• Route pendant cord to work area. Care should

be taken in running pendant cord to work area
from truck so that the cord will not be run over or
damaged.

• The remote-operated relief valve must only be used

with a safety person. The safety person must be
holding the remote and must be in a position to
observe the person(s) operating the vacuum hose.
Never attach the remote to the work hose or to the
person actually vacuuming up the product since
situations could develop wherein the person using
the vacuum hose may not be able to reach the
remote.

• If the safety person observes an unsafe or dangerous

action of any type, he/she should immediately press
the VENT OPEN button (1) on the remote pendant.
Only after all potential dangers have been removed
should the vent door be closed and normal vacuum
operations continue. The safety person should
continue to be in a position to observe all vacuum
hose operators until those operators have moved a
safe distance from the end of all vacuum work hoses.

• After vacuum operation is completed and the vacuum

pump is shut down, properly store pendant to prevent
damage when truck is being moved.

Failure to comply with this could result in serious
personal injury or death.
