WORK ENVIRONMENT
The machines manufactured by Merlo S.p.a., are designed to be used within the following environmental temperature ranges:
- minimum temperature: - 20°C
- maximum temperature: + 40°C
Always take the atmospheric and climatic conditions of the workplace into account.
Special applications may be provided on request for particularly cold or hot environments.
A single fire extinguisher should be fitted on the machine when the workplace does not have external fire extinguishing
equipment and the risk of fires exists.
The machine is supplied with a leaflet stating the maximum permissible wind under normal operating conditions. Before using

(level 6 on the "Beaufort scale").
