DANGER
Vacuum and Boom Operation
The boom is operated off the main hydraulic system
when engaged in work mode and is activated when the
front control panel is set to VAC.
1.
At the front control panel, locate the 4-way boom
control joystick. Make sure the vacuum hose chain
hook at the front bumper is released before swinging
the boom. You may need to retract the boom. By
moving the joystick in one of four directions, the
boom will go up, down, left, or right. The boom will
extend and retract with the use of the rocker switches
provided on top of the joystick controls. The boom will
swing 120° each way from the centerline of the truck
for a total of 240°. A mechanical stop will
automatically limit the maximum swing.

2.
Connect the required intake vacuum tubes (or dig
tubes) onto the boom. Make sure O-rings are
positioned correctly on the couplings and the center
clamp is fully closed. Use the shortest possible
length of tubing to ensure the most direct route.
3.
The jetting operation can now be started. Open the
sewer hose valve and slowly increase the water
pressure on the jetting head.
4.
Send the sewer hose upstream using the lowest
water pressure possible.
5.
Once at the end target, increase the water pressure
and return the hose slowly.
6.
Once debris is observed or the operator hears debris
hitting the vacuum tubes, begin vacuuming by closing
the vent door.
DANGER
7.
When the jetting operation is complete, shut off the
water, open the vent door, and disconnect the tubes.
WARNING
• Avoid close contact with a pressurized hose.
Injury could result from hose bursts or
coupling failure. When in close contact,
relieve the pressure either by dialing the
water pressure back to zero and/or opening
the return to tank ball valve.
• Keep the containment shield in position and
operating properly to avoid personal injury or
death from sewer hose bursts or coupling
failure. Replace the containment shield
immediately if it becomes damaged.
• When operating the boom, make sure you are
aware of all personnel and that the swing path
for the boom will not hit any person or
obstruction. Failure to comply could result in
personal injury and/or property damage.
• When operating the boom, make sure you
watch for overhead electrical wires or
anything else that could result in personal
injury or property damage.
• The boom can be lowered below horizontal
when rotated to the side of the truck. Make
sure it does not come in contact with any part
of the truck.
Boom Warning
Never allow the cleaning nozzle to come out of
the sewer line. If this happens, the cleaning
nozzle will whip uncontrollably and could cause
damage or death.
Return the boom to the cradle before moving the
truck. Moving the truck with the boom out of the
cradle could cause excessive boom wear or
failure, resulting in severe personal injury or
death.
