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)

02.11 –Instructions for use
02.11.01 –Before use
Make a visual check to ensure the leveller is in perfect conditions of use.
Centre the vehicle against the rubber stops of the leveller.
Check that the vehicle is completely immobilised and blocked. (Switch off the engine, apply the handbrake and
place chocks on the wheels).
To raise the leveller to the load surface level, connect the manoeuvring circuit by turning the red section switch.
The green pilot light will come on.
To raise the leveller and open the lip press the elevation button without releasing it.
If you stop pressing the button, the leveller will descend at a controlled speed, due to its own weight.
Raise the leveller until the lip starts to open. Once the lip is open completely, release the elevation button.
Let the leveller descend at a steady speed until it rests on the load surface of the truck.
Check that the whole width of the lip is resting on the load surface of the vehicle in an area NO smaller than
130mm.
02.11.02 –During use
The dock leveller will merely rest on the load surface (truck). The hydraulic cylinders MUST NOT be blocked to
allow the leveller to adapt to the height of the load surface (which will vary, depending on the variation in the truck
suspension).
Check that the emergency stop is NOT activated and that the leveller is supplied with power.

Instructions manual RH14 Inkema
V05 –2016
www.inkema.com
12
VERY IMPORTANT:
It is strictly prohibited to perform loading and unloading operations with the emergency stop activated, or
while the leveller is not supplied with power.
Never exceed the maximum nominal load. (See its plate characteristics).
Ensure that the leveller continues to rest on the load surface during transit. If this is not the case, press the
emergency stop button immediately.
Fork-lift trucks must be driven with caution. The maximum transit speed calculated for the leveller is 10 km/hour.
02.11.03 –After use.
Raise the leveller and close the lip before the truck leaves the loading position. To do this, press the elevation
button and raise the leveller just enough for it to clear the truck.
Release the button and wait for the leveller to descend at a steady speed and rest on the closed lip on the front of the
inferior structure.
02.11.04 –Precautions during use.
Check that the emergency stop is not activated.
Never exceed the maximum nominal load. (See its plate characteristics).
Before each manoeuvre check that no-one is in the work area.
Check that the leveller is resting properly on the load surface of the truck, with the entire lip coupled to a surface of
approximately 130 mm along its whole width.
The hydraulic unit has the sole function of making the necessary movements to manipulate only the dock leveller.
It must never be used to support and/or lift loads.
Before raising the device ensure that its movement is not blocked by other equipment. (Doors, etc... )
After completing the operation check that the lip is properly inserted in the closed leveller position.

05 –Installation
05.01 –Transportation
The machine is completely folded during transportation. In order to load more units of the transport space.
05.02 –Positioning in the pit
VERY IMPORTANT: When handling the leveller, always respect the occupation risk prevention legislation and
the regulations regarding safety, hygiene and health at work.
Place it in the pit with the help of a crane, fork lift truck or similar element, using the worm screws, and chains,
slings and similar items to lift it. With a load capacity equal to or greater than the weight of the leveller.
To position it, the anchoring parts will be screwed to enable the leveller to be held and supported in the pit.
Then unwind the electrical cable and pass it through the tube that is centred at the back of the pit. Once the cable
has emerged at the other end of the tube, position the leveller correctly in the pit.
Then centre and position the rear hinged unit of the machine, supporting it on the inverted “L” profile at the back of
the pit.
Weld the rear part of the machine to the pit using 5 weld cords with a throat of 6mm and length of 100mm with a
distribution and separation between them of 375mm.
The weld areas are indicated in the following diagram:
Unscrew the front support and position it on the inferior structure (see the previous figure).
Pull the front with the cylinders until it is in the correct position, so that when the lip is resting on the supports the
machine is completely horizontal and the front does not protrude from the pit. Normally there must be a margin of
between 10mm and 30mm between the front and the pit. (See the following diagrams).

Parts for Handling

Instructions manual RH14 Inkema
V05 –2016

17
Weld the front part of the machine to the inferior structure using 2 weld cords with a throat of 6mm and length of
200mm centred with respect to the front supports of the lip.
Once all the welding has been done remove the rear anchoring parts.
05.03 –Installing the electrical control panel
The electrical panel must be installed in the wall on the truck driver side, to allow the dock leveller operator to see
and talk to the driver if necessary. (See electrical control panel connections, page 19)
Secure the electrical panel box to the wall at the desired height and perfectly aligned with the output of the leveller
cables, approximately 1300mm from the floor.
Adjust the tube for the electrical cables to pass through at the existing distance between the panel and floor.
Secure the tube to the wall (using at least 3 brackets); it must be perpendicular to the loading bay floor and aligned
with the leveller output cables.
The plastic tube is delivered sealed to one of the two sides of the leveller inferior structure.

Once everything is secured, pass the cables through and connect, pursuant to the attached electrical diagram which
is inside the electrical control panel. (See electrical control panel connections, page 19)
05.04 –Completed installation
Eliminate the front flanges joining the lip to the inferior structure.
VERY IMPORTANT: Weld the lateral panels, removing the rivet that holds them in place and check their
movement and functionality.
Lastly, check the condition of the leveller paint, correcting any flaws (including the levelling plates).
The installation is considered completed when the installer authorised by INKEMA has filled in the respective
installation control sheet.
