02.10 –Maintenance
The correct operation and long life of the ramp depend largely on the preventive maintenance work carried out.
Advanced maintenance may only be carried out by the INKEMA technical service or staff authorised by the latter.
This maintenance is carried out to ensure that the product conserves the safety and usage characteristics it had when
it was first installed.
All changes, repairs or manipulation of the product that do not comply with these regulations will lead to the
cancellation of the one-year warranty term and the liability of INKEMA for the product will automatically end.
Continuous greasing, painting and vigilance is the best way to guarantee its performance for many years.
02.10.01 –Hydraulic oil
The hydraulic oil must be replaced every two years.
The oil must contain agents that prevent the formation of foam, oxidation and water absorption. If the winter
temperatures are very low, the oil must not be too thick and its viscosity index must remain stable at low
temperatures.
Never mix different oils, as the new oil may have a different resistance to oxidation and affect the life of the
original oil.
It is important to check the oil level every 6 months. The oil tank must be filled until it almost overflows from the
closing cap, in the lowest possible position.
The machine is supplied already containing T-15 oil
Hydraulic oil for levellers in refrigerated storerooms must have specific properties of use, in accordance with the
temperatures to which it is exposed. For this reason, if the need arises, the manufacturer must be informed about the
conditions in which the machine will be operating to ensure it contains the special oil.
02.10.02 –Grease points.
Every six months, check the grease points shown in the diagram
02.10.03 –Dock leveller descent speed regulation
The speed will be regulated using the respective adjuster (1). (See hydraulic unit, page 7)
02.10.04 –Lip opening speed
The lip opening/closing speed is determined in the factory, but can be regulated using the respective adjuster (2).
(See hydraulic unit, page 7)
