TY
DANGER
When draining the fuel, do not smoke or bring naked
flames near the machine.
Place a container under the machine to gather the fuel
and prevent it from spreading around.
If some fuel is spilt, clean the dirty surface immediately.
IMPORTANT
To protect the cylinder rods when the machine is not
used, position the work equipment as shown in the figure.
(This serves to prevent the cylinder rods from rusting).
If the machine must be stored for a long period of inactivity, it is advisable to put it in a sheltered place and to take
the following precautions, in order to keep all its components sound and efficient:
1 - Clean the machine thoroughly, repainting it where necessary in order to prevent oxidation.
2 - Drain and change all the fluids of the hydraulic circuits and the lubricants (engine and reduction gears), fol-
lowing the maintenance rules.
3 - Change all the filtering elements (air cleaner, engine oil filter, hydraulic circuit filters, diesel oil filter).
4 - Drain the coolant and replace it with a corrosion inhibitor (permanent fluid).
5 - Drain the normal fuel and fill the tank with at least 5 liters of special washing and protecting fuel.
6 - Let the engine run for about 10 minutes, in such a way as to eliminate the residual normal fuel from the fil-
ters, the injection pump and the entire fuel supply system. This operation avoids the locking of the injection
pump and the injectors.
Stop the engine and refuel with normal diesel oil.
7 - Remove the battery, check the electrolyte level and make sure that the battery charge is sufficient.
Store the battery in a room with suitable temperature and periodically recharge it.
8 - Grease the hydraulic cylinder rods and the equipment joints.
9 - Seal the end of the exhaust pipe and the fuel tank cap.
10 - Move the machine controls to the neutral position and engage all the safety locks.
11 - Hang a warning notice on the controls to indicate the condition of the machine.
12 - Lock the fuel tank cap, the engine hood and, if provided, the cab door.
