IMPORTANT SAFETY NOTICE
Fire Safety Conditional Approvals
A fire safety conditional approval must be issued by an appropriate licensed
electrical engineer for use of this sewer camera in areas of a sewer that have
been demonstrated by testing and monitoring not to fall under the “Fire
Safety Approval” requirement in Section 2540.2 of Title 8 of the California
Code of Regulations. Testing and monitoring will be considered by the
California Division of Occupational Safety and Health, to be sufficient for
this purpose if all measurements indicate that the sewer atmosphere is below
10% of the lower explosive limit (LEL) and if the user meets all of the
following additional conditions:
(1)
Before each use, inspects cable and electrical equipment for damage
or wear that could compromise safety;
(2)
Test operates the sewer camera and associated electrical equipment in
a dry location away from any potential exposure to hazardous
conditions to determine whether the equipment functions normally
and without any problems, such as sparking, loose connections, or
other similar safety problems;
(3)
Tests for the existence of a hazardous atmosphere prior to opening
any sewer access point using a multi-gas tester, and before energizing
the equipment, conducts a test of the sewer atmosphere at the access
point estimated to be closest to the end point of the camera work;
(4)
Provides continuous monitoring in the alarm mode at the access point
from which the work is performed at all times while the sewer
inspection camera is energized in the sewer;
(5)
De-energizes all electrical equipment and uses mechanical ventilation
of a measurement exceeding 10% of the LEL is obtained;
and Discontinues use of all electrical equipment if the sewer
environment cannot be maintained below 10%.

Operator and Equipment Safety
It is important to be familiar with operations, maintenance, and safety issues
when working with RST equipment.
Read the entire manual before operating the equipment.
To prevent personal injury or damage to equipment, turn off Camera power.
When making electrical connections, width adjustments and when maintaining
the tractor or camera, disconnect all power to the control station before
servicing.
Inspect all transport, camera, lighting cables, and bridles before and after each
use. Replace any broken, worn or frayed bridles or cables.
Always use care when near an open manhole, and when climbing in or out of a
TV inspection vehicle. The tractor and camera assembly can be placed into the
pipeline without personnel entering the manhole. Use proper lifting ropes,
cranes and winches for lifting equipment in/out of pipes.
Document Number 900-20576 Rev C

Set up
Before you can begin to televise the line, set up for the proper pipeline size. It
may be necessary to set up the main line tractor one size smaller the than the
pipeline being inspected. For larger line sizes, the most common size change will
be made by adding extensions. Set camera forks level or above flow of pipe to
keep the lens out of the water. To adjust cradle, bend up at a 90-degree angle,
loosen or tighten bolt and jam nut as necessary. Another method is to raise
camera using balloon carriage assembly.

Cable Grip Adjustment
Check cable grip for proper adjustment. If adjustment is needed:
Clean out cap screws on cable grip as well as cable.
Loosen four cap screws on cable grip.
With the screws loose, it may be necessary to pop cable grip on a hard surface
to separate halves from cable.
Slide cable grip to allow for proper slack. The cable grip should be adjusted to
provide slack in the watertight connection, when bridle is tight. There should be
enough slack to allow wire area to bend, but not enough to bend boot area when
cable is raised at a 90-degree angle while loading and unloading equipment.
Retighten cap screws on cable grip. The halves should be tightened evenly to
prevent binding. Always use a cross pattern when tightening cable grip.
WARNING! IMPROPER CABLE GRIP ADJUSTMENT
CAUSES ROLLOVERS AND WATERTIGHT
CONNECTION FAILURE!

Tread Drive Set Up
INSTALLATION INSTRUCTIONS
MAINLINE TRACTOR
TRACTOR TREAD DRIVE OPTION
P/N 032-02100
Required Tools:
#2 Phillips head screw driver
1/8” hex key
3/32” hex key
5/16” hex key (included in the kit)
Note: Please read these instructions prior to starting the installation process.
This instruction outlines the steps to configure the tractor for use in an eightinch line. If the tractor is to be used to inspect a larger line, the skid set does
not need to be changed. See the note following step 8 for instructions on
selecting and using the correct tread drive assembly spacers.
1. Remove the standard skid set from the tractor using a #2 Phillips screwdriver.
Note: The screws that were removed from the rear mounting holes are
shorter than the front mounting screws.
2. Install the optional tread drive skid set. Reuse the screws that were removed.
Make sure to use the shorter screws to fasten the rear of the skid to the tractor
motor.
Note: One end of each skid has been specially machined to provide proper
clearance. The edge with the large radius must face down and toward the
front. Prior to installing the second skid, make sure that there are no twists
in the cable tow bridle. The skid set included with this option must be
installed if the tractor is going to be used in an eight-inch line.
Document Number 900-20576 Rev C
11
The special skid set will perform as well as a standard skid set when the
tractor is used with wheels.
3. Place the tractor on its right side. Remove the three wheel assemblies with a 1/8”
hex key. Clean any debris from the two ½”-13 threaded holes located in the
tractor side plate. Place one of the ½” non-threaded spacers over each of the ½”13 threaded holes.
4. Identify the left side tread drive assembly. To do this, locate the tread drive
assembly that will have the black plastic rub strip facing the bottom when the
tread drive assembly is mounted on the tractor body.
Note: The tractor drive assemblies are driven by the tractor’s front drive axle.
5. Place the tread drive assembly on a flat surface. Make sure that the tread drive
assembly drive hub is facing down. Insert a ½”-13 x 1.75” button head bolt into
each of the ½” mounting holes located in the tread drive assembly. Align the two
½”-13 bolts over the two ½” spacers and align the drive hub over the tractor front
drive axle. Lower the tread drives assembly into place. Tighten the ½”-13 bolts
with the 5/16” hex key.
6. Turn the drive chain until the setscrew in the drive hub is aligned with the
machined slot located on the tractor front drive axle. Tighten the drive hub set
screw using the 3/32” hex key.
7. Check the drive chain for proper tension by placing the 5/16” hex key between
the chain and the tread drive side plate. Perform this test at the midpoint of the
side plate. Correct drive chain tension is achieved when the 5/16” hex key fits
freely between the chain and the side plate. If required adjust the chain tension
by turning the pan head screw located near the center of the tread drive
assembly. Turn the screw clockwise to tighten the chain or counter-clockwise to
loosen the chain.
8. Install the right side tread drive assembly using the procedure outlined above.
The tractor is now ready for use in an 8” line.
Note: The tread drive option includes the spacers that are required when
the tractor will be run in lines larger than 8”. Select the appropriate axle
extension for use in the line to be inspected. Select the matching threaded
spacer included with the tread drive option. After removing the wheel
assemblies, install the selected axle extensions on the tractor’s front drive
axle. After cleaning the ½”-13 threaded holes, install the threaded spacers
into the threaded holes. Make sure the body of the threaded spacers make
contact with the tractor side plate. Place the ½” non-threaded spacers on
top of the installed threaded spacers. Install the tread drive assembly as
described above.

System Power
CAUTION: NEVER HOOK UP OR DISCONNECT ANY EQUIPMENT WITH
POWER TURNED ON!
The Inspection System requires a steady supply of 120VAC to operate properly.
Before starting of the generator or connecting shore power, make sure that ALL
equipment inside the vehicle has been turned OFF. Turn down the controls for
camera power and cable reel speed. After all equipment has been checked,
connect the shore power cord.
If a generator is to be used, allow the generator to warm up for a few minutes.
Note: Diesel generators use a different control panel that is separate from the
controller power supply. Refer to the appropriate generator operators manual for
starting.
Verify that the voltage and frequency indicators on the controller power supply are
in the green normal zone.
Caution: Before turning on any equipment, plug the keyboard into the data
collection system. Plug the Auxiliary Control Box into the Auxiliary Control
jack on the controller power supply.
Caution: If the voltage or frequency fluctuates into the red zones on the
controller power supply, DO NOT turn on any of the equipment in the truck.
Check shore power or the generator for proper operation, or have them
checked by a qualified technician.
Caution: Route cords away from traffic or wet areas to avoid tripping on
power cords.
Document Number 900-20576 Rev C

Lowering Equipment into Pipeline
Locate the back of the truck so that the cable reel lines up in the direction of the
pipeline to be inspected. Allow room to work around the opening while carrying
the equipment.
Follow cable grip, bridle, and watertight connection instructions. Re-check the
pipeline size and extension adjustments. Do not let cable “loop” at the location
where it enters pipeline. Use guide poles with hook to keep the tractor stable as it
enters pipeline.
Caution: Maintain control of equipment while lowering and lifting
from manhole.
Most equipment damage occurs when camera is lowered into hole.
Pull camera/tractor far enough into pipeline to clear the bridle or cable grip.
Set the cable guide. Use double roller and/or single rollers, for protecting the
cable and allowing it to slide down the hole without drag on the line. Use enough
poles to clear top of the manhole by 2 feet.
Caution: Watch out for people, power lines and traffic when
handling the downhole pole
Put cable reel into “freewheel” and reel off enough cable so camera and tractor
can be lowered into the bottom of the manhole. Place lowering rope ring under
the top front runner or front of camera. Support weight of tractor and camera with
the cable in one hand and rope in the other.
NOTE: RST skycrane can be used in place of the cable and rope method.
Slowly lower the front of camera into manhole to clear manhole ring. Lower
tractor and camera to the bottom of manhole facing camera in the direction of the
pipeline to be inspected. When tractor and camera are resting on bottom of
manhole, release the rope ring and remove it from the manhole.
Check all camera and tractor functions again before proceeding. Move tractor
forward so the rear of the tractor and the cable connections are fully inside the
pipe. The use of guide poles with a hook will help to keep the tractor stable as it
enters the pipeline.
Install the down hole pole, double roller, and top manhole roller. The use of
double roller and/or single roller is for protecting the cable and allowing it to slide
down the hole without drag on the line. Remove any slack from the cable and
reset the footage counter. It is best to do this by hand or with cable reel set to low
speed.
The tractor has an automatic “disengage” feature that allows for the freewheeling
retrieval. To disengage the tractor, reverse its direction momentarily . This will
disengage the drive mechanism and allow the tractor to be pulled out of the
pipeline in “freewheel” by the cable reel.
Document Number 900-20576 Rev C
14
Retrieval of the Equipment
Ending the Run
Make sure tractor is in “free wheel”.
Use low speed while retrieving tractor.
Use care when removing camera from line.
Back tractor out of pipe into manhole so that front of tractor is clear of pipe.
Remove rollers and poles to make room to lift tractor and camera from manhole.
Lower rope with ring and catch the end of camera at the same place used to
lower tractor and camera.
Lift tractor and camera assembly from manhole using the rope and cable.
NOTE: RST skycrane can be used in place of the cable and rope retrieval
method.
Keep the camera clear of any ladders or drop lines.
When tractor and camera are out of hole:
Turn down light power on camera,
Turn off camera power,
Wash unit over hole,
Wipe down and store the cable, camera, and tractor.
Document Number 900-20576 Rev C
