General
1 The Vision 5LF head requires a minimum of periodic servicing. Its rotational and drag mechanisms are
totally enclosed to prevent the ingress of dirt or foreign bodies. If the head becomes faulty reference should be
made to Section 5 of this manual, or the unit may be returned to Vinten Broadcast Limited or your local
distributor for overhaul.
Cleaning
2 During indoor use, the only cleaning required should be a regular wipe over with a lint-free cloth. Dirt
accumulated during storage may be removed using a semi-stiff brush. Particular attention should be paid to
the levelling ball and mounting face of the head and to the space between the tilting assembly and the base.
3 The Vision 5LF head is weatherproof. However, use out-of-doors under adverse conditions will require
special attention. Salt spray should be washed off with fresh water at the earliest opportunity. Sand and dirt
acts as an abrasive and should be removed using a semi-stiff brush or vacuum cleaner
Lubrication
4 The bearings in the pan and tilt head are packed with grease. Under normal operating conditions they
will only require re-greasing if there is any harshness or stiffness in movement. Refer to Section 5 to dismantle
the head for re-greasing.
5 To check the bearings, turn the balance control as far as possible counter-clockwise, turn the pan and
tilt drag controls fully counter-clockwise and release the brakes. At these settings both pan and tilt axes
should move smoothly and without perceptible drag.
NOTE: Use only detergent-based cleaners. DO NOT use solvent- or oil-based cleaners, abrasives
or wire brushes to remove accumulations of dirt, as these damage the protective surfaces.
