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 the optional wireless
remote control. 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
remote control 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.

• For pendant remote control:
• Insert the pendant cord into the socket located
at the front control panel on the passenger side.
• 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.
