3.6.1.2 DAILY CHECKS
WARNING
q
Do not smoke while refuelling or topping up the oils and do not use naked flames or non-homologated
lighting means to check the fuel and oil levels, in order not to cause fires.
q
If fuel, oil, or lubricant are spilled while filling the tanks, clean the dirty areas immediately.
Before starting any operation, check the engine coolant, engine oil and hydraulic circuit oil levels.
At the end of work, provide for refuelling, in order to avoid the formation of condensation, always checking the fuel
level on the indicator provided on the dashboard.
IMPORTANT
q
Avoid filling the tank completely, in order to leave room for the diesel oil to expand.
q
After refuelling, put back the filler cap, making sure that the breather hole is completely open.
q
Check the engine oil level and the hydraulic circuit oil level with the machine in horizontal position and
the bucket resting on the ground.
