Safety Precautions before Maintenance
WARNING!
ELECTRICAL SHOCK HAZARD. Disconnect the Power Supply when
servicing the equipment. The Power Supply Box is powered even when the E-Stop Pushbutton is
latched in off position.
WARNING!
MAGNETIC MATERIAL. The wheels on the crawler produce an extremely
strong magnetic field which may cause failure or permanent damage to items such as watches,
memory devices, CRT monitors, medical devices, or other electronics. Tools, magnets, and metal
objects can cut, pinch, or entrap hands and fingers. HANDLE WITH CARE. People with pacemakers
or ICD’s must stay at least 2m (79’’) away.

Maintenance Schedule
The Tri Pod system must be maintained according to the following schedule:
Maintenance Item
Frequency
Inspect Safety Apparatus
This includes:
• All components of Tether System. Replace damaged components as necessary.
• Lifting Sling on crawler. If the Lifting Sling shows signs of damage (i.e cuts,
abrasion, etc), do NOT use.
Every Use
Clean the Drive Wheels
Since the Drive Wheels are magnetic, debris will build up on them. This debris must
be cleaned off before every use. An effective cleaning method is to use adhesive-
backed tape (i.e. duct tape) to ‘pull’ the debris off the wheels.
Inspect Cables and Connectors
Inspect the Umbilical Cable, the Control Cable, and the Power Supply Cable for
damage. Repair by a qualified person or replace the cable assembly as necessary.
Inspect all connectors for damage or moisture. Straighten bent pins. Dry connectors
before using.
Every Use
General Cleaning
Ensure that the scanner stays relatively clean by wiping off any excess dirt or other
contaminants after every use.
Check Drive Wheel Backlash
Check each Drive Wheel individually for free-play by rotating back and forth by hand.
If the free-play allows the wheel to move more than 2 teeth (if you see more than 2
teeth on the outer diameter of the wheel move past a stationary point), check to see
that the M6x16 Screw (see Fig. 19; item #28) is tight. If the screw is tight, the crawler
must be serviced. Contact the manufacturer before further use (see page 3).
