Drum Brake
The drum is equipped with a spring bolt on the main drive sprocket intended for storage and transport
only. Lock the drum with the spring bolt whenever the winch is not in use.
Warning:
Never apply the spring bolt drum lock while the drum is turning.
Manual Cranking
If the winch becomes disabled, or more pulling force is needed than the drive motor can provide, the
winch may be manually cranked.
1. Disengage the drive clutch.
2. Insert the manual crank handle.
Warning:
The crank gives you a mechanical advantage of 10:1. A tether pulling force of up to
500 pounds can be generated.
Dealing with Obstacles
The operator will invariably encounter a range of obstacles in a pipe. Each time the operator must decide

•
Sand
•
Rocks / Debris
•
Roots
•
Intersecting service pipes
•
Animals and their nests
The VT300
™ vehicle naturally straddles the debris at the very bottom of a pipe. If the debris is high you
may try installing the track extension brackets to give the chassis more clearance. Additionally, the inside
track weights may be removed to increase center clearance.
If the operator is unsure about pipe navigability, he should consult with the site supervisor before moving
forward.
Inspection Guidelines
The objective of an inspection is to obtain a recording of video and other data for review by the customer
or pipe owner. If a recording is lost, fails to record, or is of poor quality the inspection will likely have to be
re-done at the
operators’ expense. It is therefore in the operators’ best interest to verify vehicle operation,
video quality and recorder function before beginning each inspection. A set of video-overlay comments
and data are usually required depending on the contract or client. Initial comments will usually include the
