5 Installation and Operating Conditions
5.1 Safety
➤ Strictly forbid fire, open flame and smoking.
➤ If welding is carried out on or near the machine, take adequate measures to prevent sparks or
heat from igniting fuel or oil vapours or parts of the machine.
➤ The machine is not explosion-proof!
Do not operate in areas in which specific requirements regarding explosion protection are in force.
For instance, the requirements of ATEX directive 94/9/EC "Equipment and Protective Systems
intended for use in Potentially Explosive Atmospheres".
➤ Ensure that required ambient conditions are maintained with regard to:
■ ambient temperature,
■ clean inlet air with no damaging contaminants,
■ inlet air free of explosive or chemically unstable gases or vapours,
■ inlet air free of acid/alkaline forming substances, particularly ammonia, chlorine or hydrogen
sulphide.
➤ Keep suitable fire extinguishing agents ready for use.
5.2 Installation conditions
Precondition The ground must be level, firm and capable of bearing the weight of the machine.
Fig. 22 Minimum distance from excavations/slopes and walls
1. Keep sufficient distance (at least 1.5 m) from the edges of excavations and slopes.
2. Ensure that the machine is as level as possible.
The machine can be temporarily operated on a slope of not more than 15°.
3. Ensure accessibility so that all work on the machine can be carried out without danger or hin‐
drance.
CAUTION
Fire hazard from build-up of heat and hot exhaust system!
Insufficient distance from a wall may well cause heat build-up that could damage the machine.
➤ Do not position the machine directly against a wall.
➤ Ensure always sufficient ventilation space around the machine.
4. Position the machine as far as possible from any wall.
