SEWER CLEANING — TYPICAL SEQUENCE
4
Water Pump Operation — Jetting
Determine what work will need to be performed at the job
site to facilitate the proper positioning of the truck. Let’s
assume that we will clean a 12 in. storm line and catch
basin and will need to vacuum the material that is
backflushed. The handgun may be needed as well.
Starting Sewer Cleaning — Typical
Sequence
NOTE
If the front mount hose reel cannot be placed directly
over the drain, an upper manhole roller guide should
be used to protect the jetting hose from damage. The
front mount hose reel will operate in a 180° radius.
1.
Make sure the truck’s parking brakes are set and the
cab control panel is in work mode. Let the engine idle
and turn on the appropriate flashers, strobes, arrow
boards, etc. Put on the proper PPE. Place wheel
chocks in front of and behind one of the rear tires.
Place safety cones as needed.
2.
Retrieve the following items from the tool box:
• Manhole hook to remove the drain cover.
Tiger tail to protect the jetting hose.
3.
Position the truck so that the hose guide is positioned
just over the drain on the downstream side if
possible. To position the hose guide, remove the
transport locking pin (1) on the front of the hose reel
and unlock the hose reel base rotation brake (2) by
pulling the knob out. Leave the hose reel brake in the
RELEASE position at this time.

4.
For remote manhole operations, the water pump may
be operated with the containment shield raised, and
the sewer hose does not need to be routed through
the hose guide. See Figures 4-10 and 4-11 below for
the location of containment shield latches.
