General
Vision products are robustly made to high engineering standards and little attention is required to
maintain serviceability save regular cleaning. Attention to the following points will ensure a long
and useful service life with minimum need for repair.
Cleaning
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.
All dolly parts are 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
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.
Routine checks
Check the following during normal use:
Check for ageing and cracking of the rubber strut securing straps and renew if necessary.
On studio dollies, check the tracking
Adjustments
Adjustments to the tracking of studio dollies may become necessary after considerable use.
Check the tracking as follows:
With the track locks engaged and a payload fitted, the dolly should track in a straight line
over a distance of 3.6 m (12 feet) with deviation not exceeding 5 cm (2 in.). If this cannot
be achieved, the wheels should be re-aligned. When re-aligning the wheels, start by adjust-
ing the wheel with the red locking knob on the fixed leg. This will often correct any alignment
problems.
