Safety regulations
Checking the Roll Over Protective
Structure (ROPS)
i
Note
On machines with cab the ROPS is an integral part
of the cab.
The frame of the machine must not be warped,
bent or cracked in the area of the ROPS fastening.
The ROPS must not show any rust, damage, hair-
line cracks or open fractures.
The actual weight of the machine must not exceed
the testing weight of the ROPS.
The ROPS must not rattle about when driving.
This indicates that it is not properly fastened. All
bolted connections must comply with the specifi-
cations and should be absolutely tight (observe
the tightening torques). Screw and nuts must not
be damaged, bent or deformed.
With the cab assembled check also the state of the
cabin mounts (rubber elements and screws).
No accessories may be welded or bolted on and
no additional holes must be drilled without the con-
sent of the manufacturer, since this will impair the
strength of the unit.
The ROPS must therefore also not be straight-
ened or repaired if it is damaged.
A defect ROPS must generally be replaced with an
original spare part in close coordination with the
manufacturer.
Starting the machine
Before starting
Operation of the machine is only permitted when
sitting in the operator's seat.
Use only machines which have been properly
serviced at regular intervals.
Become acquainted with the equipment, the con-
trol elements, the working mode of the machine
and the area you will be working in.
Use your personal protective outfit (hard hat, safe-
ty boots etc.).
Check before mounting the machine if:
there are persons or obstructions beside or
l
under the machine
16
the machine is free of any oily and combustible
l
material
all handrails, steps and platforms are free of
l
grease, oils, fuels, dirt, snow and ice
the engine compartment hood is closed and
l
locked
To climb onto the machine use steps and hand-
rails.
Check before starting, whether:
the machine shows any obvious defects
l
all protective devices are properly secured in
l
their place
steering, brakes, control elements, lighting
l
and warning horn are in order
the seat is correctly adjusted
l
the mirrors (if available) are clean and correct-
l
ly adjusted.
Do not start the machine if any gauges, control
lights or controls are defective.
Do not take any loose objects with you or fasten
them to the machine.
On machines with ROPS you should always wear
your seat belt!
Starting
Start and operate the machine only from the oper-
ator's seat
For starting set all control levers to "neutral posi-
tion".
Do not use any starting aids such as Start Pilot or
ether.
After starting check all gauges.
Starting with jump leads
Connect plus with plus and minus with minus
(ground cable) - always connect the ground cable
last and disconnect it first! Wrong connections
may cause severe damage in the electric system.
Never start the engine by bridging the electrical
connections on the starter, because the machine
would probably start to move immediately.
Starting in closed rooms
Exhaust gases are toxic! Always ensure an ade-
quate supply of fresh air when starting in closed
rooms!
