Safety
General Information
Ensure that the operator reads and understands the decals and consults the manuals before
maintenance or operation.
Ensure that the Operation andMaintenance manual, and the manual holder, are not removed
permanently from the machine.
Ensure that maintenance personnel are adequately trained, competent and have read the
Maintenance manuals.
Make sure that all protective covers are in place and that the canopy/doors are closed during
operation.
The specification of this machine is such that the machine is not suitable for use in flammable
gas risk areas. If such an application is required then all local regulations, codes of practice
andsiterulesmustbeobserved.Toensurethatthemachinecanoperatein a safeandreliable
manner, additional equipment such as gas detection, exhaust spark arrestors, and intake
(shut-off) valves may be required, dependent on local regulations or the degree of risk
involved.
A weekly visual check must be made on all fasteners/fixing screws securing mechanical parts.
In particular, safety-related parts such as coupling hitch, drawbar components, road-wheels,
and lifting bail should be checked for total security.
All components which are loose, damaged or unserviceable, must be rectified without delay.

Book 23015142 (5-08-07) Rev B 13
Compressed Air
Compressed air can be dangerous if incorrectly handled. Before doing any work on the unit,
ensure that all pressure is vented from the system and that the machine cannot be started
accidentally.
Ensure that the machine is operating at the rated pressure and that the rated pressure is
known to all relevant personnel.
All air pressure equipment installed in or connected to the machine must have safe working
pressure ratings of at least the machine rated pressure.
If more than one compressor is connected to one common downstream plant, effective check
valves and isolation valves must be fitted and controlled by work procedures, so that one
machine cannot accidently be pressurised / over pressurised by another.
Compressed air must not be used for adirect feed to any form ofbreathing apparatusor mask.
If the discharged air is to be ultimately released into a confined space, adequate ventilation
must be provided.
When using compressed air always use appropriate personal protective equipment.
All pressure containing parts, especially flexible hoses and their couplings, must be regularly
inspected, be free from defects and be replaced according to the Manual instructions.
Avoid bodily contact with compressed air.
The safety valve located in the discharge piping must be checked periodically for correct
operation.
Materials
The following substances may be produced during the operation of this machine:
• brake lining dust
• engine exhaust fumes
