Protect the stages from welding spatter, splashes of paint and other foreign bodies during mounting.

• Fit a relief valve to the hydraulic system, set to 200 Bars.
• Clean inside the reservoirs and pipelines and fit suitable filters, and leak of air the circuit before use.
• When at rest the closed cylinder must not support the body, should be at least 20 mm.
• We suggest fixing the cylinder in the middle of the body trailer.
• Check that during the tipping the cylinder does not hinder to the body components, and check the angle of cup ball.
• It is recommended not to use aggressive solvents and degreasers for cleaning the seals.
• Use mineral hydraulic oils and lubricants with a viscosity of 10 to 46 cSt at 50°C.

We suggest a mineral hydraulic oil high index ISO32, Mobil-Shell-Valvoline-Bechem.

• We recommend the use of grease HIGH – LUB LT 1 EP or LGMT 2 for maintenance.
• Recommended oil density:
  – ISO 22 for cold climate temperatures
  – ISO 32 for average climate temperatures
  – ISO 46 for warm climate temperatures
• We recommended the use of brackets with grease nipple and cradles, all Di Natale – Bertelli originals accessories.
• Request to Di Natale – Bertelli manual for installers and user manual.

• Never exceed the maximum working pressure.
• Always ensure the load is within the maximum payload.
• Always ensure that the load is evenly distributed.
• Tip on firm level ground.
• Do not move the vehicle during tipping, It is forbidden rapid operation of the cylinder tipper control to help the material unload.
• Before tipping ensure working area is clear of people and obstructions.
• If the body does not tip smoothly, immediately lower and check cause.
• Do not shunt the vehicle to loosen sticking loads.
• If the load sticks lower the body before resuming tipping operation.
• Always verify that tyre pressure is correct.
• Never work under a body unless it is correctly propped and in a safe environment.
• Never tamper with pressure relief valve or end of stroke valve for cylinder.

We recommended using the nipple with the pressure check valve stopping the dump body stroke in case of damage or breakage of the oil piping.
