Step 10: As digging continues
to expose the utility, be aware of changes in soil conditions. A soft area that
allows faster penetration typically means the tool is approaching the utility.
Step 11: When
resistance is encountered, stop. Remove the tool from the pothole and identify the utility or
obstruction.
Step 12: If
the utility cannot be completely exposed from one hole, enlarge the hole using the tool until the
complete utility is visible. It is important to observe the entire utility to determine its size.
If utility is not located, increase size of the hole
or move to a new location.
Step 13: When the
utility has been located, release water supply trigger. Turn OFF water pump and engine.
Step 14: When
fluid level in the spoil tank reaches
capacity, the engine automatically shuts
down to prevent overfilling. When this occurs,
empty the spoil tank. Refer to “Dumping
Spoil Tank,” pa
ge 50-19.
Step 15: When finished potholing, close
Hose Reel ball
valve (5), and turn Water Pump Switch (4)
OFF.
Step 16: If engine
did not shut off automatically, follow
the Shu
tdown Procedure, page 23-1, and
remove ignition key.
Step 17: Squeeze
the water supply trigger to release
trapped water pressure prior to unhooking.
Step 18: Di
sconnect hoses. Securely store all tools and hoses before traveling to the spoil disposal site.
