Carry out a careful inspection tour around the machine each time before starting it. Check the machine for loose bolts, cracks, wear, leakage and damage. Never attempt to operate a damaged machine. Ensure that any damage is immediately rectified. Ensure that all hoods and covers are closed, but that locks are unlocked. Ensure that all warning signs are present. Keep windows and interior and exterior mirrors clean. Secure doors and windows against unintended movement. Ensure that no one is working on or under the machine and warn personnel in the vicinity of the machine that it is about to start by sounding the horn. Before starting the machine, adjust the seat, mirrors, armrests and operator’s controls in such a way that you are able to work comfortably and safely. Acoustic insulation devices on the machine must be set to the insulation position throughout operation. Only operate combustion engines and fuel-operated heaters in adequately ventilated spaces.

Starting the machine safely – Before starting, check all control lamps and instruments for correct function, place all operator’s controls in Neutral and tilt the safety lever up. – Before starting, sound the horn briefly to alert people in the vicinity of the machine. – Only start the machine from the driver’s seat. – In the absence of any other instructions, start the engine in accordance with the regulations given in the operating instructions. – Tilt the safety lever down and then test all display and checking devices. – In enclosed spaces, only allow the engine to run when there is adequate ventilation.
