MECHANICAL SERVICING

8.2.1

PRECAUTIONS

DISCONNECT THE SYSTEM POWER AND VEHICLE TETHER BEFORE COMMENCING ANY
MAINTENANCE AND/OR REPAIRS!
1) If you are unfamiliar with O-Ring seals, read Section 8.3 "Caring For O-Rings" before attempting to open
any sealed compartment or replace any O-Rings.
2) Sealed components are designed to be tight fitting. Be gentle when opening them. Forcing a component
open or closed may damage it permanently. Do not use metal tools to pry open sealed parts!
3) Many VideoRay components are anodized aluminum and will be damaged by contact with steel. If
components do not come apart with bare hands or "soft" tools, check to ensure that all fasteners have
been removed.
8.2.2

REQUIRED TOOLS

The tool kit provided with VideoRay includes all tools necessary for VideoRay maintenance. A list of
tools and spare parts is found in Section 12.
8.3

CARING FOR SEALS AND O-RINGS

VideoRay recommends the use of Dow Corning #4 Silicon Grease, as a lubricant for O-rings used as seals.
Other lubricants can lead to deterioration and failure of the O-rings and components. DO NOT USE OTHER
LUBRICANTS.
8.3.1

INSPECTION

O-rings wear out over time. Inspect all O-rings whenever a sealed assembly is apart. "Healthy" O-rings are
soft, flexible and have not been pinched or nicked. Should an O-ring appear brittle, or have apparent cracks,
nicks, or evidence of being pinched or permanently compressed, it will require replacement. Sealing surfaces
should also be inspected while an assembly is apart. The surfaces should be examined to determine that they
are free of dirt, nicks, scratches, or damage, which may result in seal failure once reassembled.
8.3.2

RULE OF THUMB

WHEN IN DOUBT, THROW IT OUT! Generally, when compared to the equipment they are protecting,
O-rings are very inexpensive. Should an incorrectly sized or damaged O-ring be installed, the result can be
very bad. If there is any doubt as to the suitability or condition of an O-ring it should be replaced.
