Products of CMCO Industrial Products GmbH have been built in accordance with the state-of-
the-art and generally accepted engineering standards. Nonetheless, incorrect handling when
using the products may cause dangers to life and limb of the user or third parties and/or
damage to the hoist or other property.
The operating company is responsible for the proper and professional instruction of the
operating personnel. For this purpose, all operators must read these operating instructions
carefully prior to the initial operation.
These operating instructions are intended to acquaint the user with the product and enable
him to use it to the full extent of its intended capabilities. The operating instructions contain
important information on how to operate the product in a safe, correct and economic way.
Acting in accordance with these instructions helps to avoid dangers, reduce repair costs and
downtimes and to increase the reliability and lifetime of the product. The operating instructions
must always be available at the place where the product is operated. Apart from the operating
instructions and the accident prevention act valid for the respective country and area where
the product is used, the commonly accepted regulations for safe and professional work must
also be adhered to.
The personnel responsible for operation, maintenance or repair of the product must read,
understand and follow these operating instructions.
The indicated protective measures will only provide the necessary safety, if the product is
operated correctly and installed and/or maintained according to the instructions. The operating
company is committed to ensure safe and trouble-free operation of the product.

Temperature limits in explosive atmospheres and dusts
The temperature range refers to -20° C up to +40° C. In case of deviating loading or
temperature ranges consult the manufacturer.
Units for operation in areas with potentially explosive gases / air resp. steam / air
atmospheres or inflammable mist
The temperatures of all equipment, protective systems and components surfaces which can
come into contact with explosive atmospheres must not exceed the ignition temperature of the
combustible gas or liquid during normal operation and in the case of malfunctions. However,
where it cannot be excluded that the gas or vapour can be heated to the temperature of the
surface, this surface temperature must not exceed 80 % of the ignition temperature of the gas
measured in °C. This value may only be exceeded in the case of rare malfunctions.
Units for operation in dust / air atmospheres
In areas, which are explosive by inflammable dusts, the surface temperature must not exceed
2/3 of the minimum ignition point in degrees Celsius (°C) of the dust/air mixture. Temperatures
of surfaces, which can be subject to dangerous deposits of ignitable dusts, must be one safety
margin lower than the minimum ignition temperature of the layer which can possibly be
generated by the respective dust. This requires a safety margin of 75 K between the minimum
ignition point of a dust deposit (ignition temperature) and the surface temperature of the unit. If
the dust deposit exceeds a thickness of 5 mm, larger safety margins are required.
