 10.2.19.4 Inspection of Devices. Inspect each stopping device and test each unit for proper
operation to make sure they will stop the manlift and report any deficiencies.
10.2.20 Signs
10.2.20.1 Operating Instructions. Signs for using the manlift shall be posted at each landing or
stenciled on the belt. Such signs should be of letters not less than one inch in height and of a
color having high contrast with the surface on which it is stenciled or painted, such as white or
yellow on black or black on white or gray. The instruction shall read approximately as follows:
Face the belt.
Use the handhold.
To stop - pull rope.
10.2.20.2 Top floor warning. At the top floor an illuminated sign must be displayed. It shall
bear the words, "Top floor - get off." Such signs shall be in block letters not less than two inches
in height. The sign shall be located within easy view of an ascending passenger and not more
than two feet above the top terminal landing. As an alternate for such a sign, a red light of not
less than a 40-watt rating may be provided immediately below the upper terminal landing and so
located as to shine in the face of a passenger.
10.2.20.3 Visitor warning. A conspicuous sign having the legend: "Employees only - visitors
keep off," shall be displayed at each landing. Such sign shall be of block letters not less than two
inches in height and of a color offering high contrast with the background color.
10.2.21 Controls
The following inspection procedure applies to all the control mechanisms, including starting
panels for the manlift drive motor. A good preventive maintenance program on the control
equipment will greatly reduce shut downs.
10.2.21.1 Inspection Made with Power Off. Open the mainline switch and examine all relays,
switches, contactors, control circuit rectifiers, transformers, capacitors, reactors, vacuum tubes,
etc. Check for excessively worn or burned contacts, broken connectors, broken or cracked
resistance grids or resistance tubes. Any fuses that are shorted with wire, solder or metal strips
must be replaced. Check whether contacts of reverse-phase relay, where provided, are open.
Examine to see that it is clean. Any accumulation of combustible materials, especially on
resistance grids or wires or on control circuit rectifiers, is a common cause of fire. Also look for
excessively worn pin hinges on relays or contactors.
