FAQs: Questions and Answers.

CAUTION! Isolate the power supply before cleaning (press the emergency button or disconnect the plug from the tractor). Check that the electrical contacts of the contact plate (between body and frame) are not dirty or oxidised.

• Check that the electrical contacts of motor and Control Box are not dirty or oxidised. If necessary, clean with a dry cloth and protect with synthetic moisture-repellent grease.Stubborn oxidation may be removed using very fine sandpaper
• Burnt motor: Replace the motor. To do so, contact Marcolin Technical Support or an authorised service centre.

• Emergency button pressed
• Incorrect electrical connections, check the electrical connections (positive – negative of the battery)
• Check the fuses. One is located in line with the power supply, the other is inside the Control Box.
• Check that the contacts of the motor are firmly connected.
• Check the condition and continuity of the motor (short circuit, burnt-out or damaged motor).

You can buy our products directly at our headquarters in Pordenone, Italy or from one of our authorized dealers. You will find the full list of our support network in this section:

• Check the alignment of the rods: Check that the closing rods on both sides are at the same distance from the fixed section. .
• Control the tension of the chain: Check the correct tensioning of the chain. 

CHPA CHAIN ADJUSTMENT:

• Adjust the automatic rear closure so that when the tarp is closed – whether manually or electrically – it automatically lowers at the end of its travel.
• Move out the tarpaulin (manually or electrically depending on the version) and cover the tipper body (fig. 1).
• Go into the internal space of the tipper body for setting up the chains (two n. 10 open-ended spanner are required);
• Let the rear closing system manually come down and readjust the chain in order that it is perfectly tightened once the rear closure has come down (fig. 2).

The polarity of the motor is reversed: Reverse the two wires connecting the contacts 3 and 4 of the Control Box.

CAUTION!  Isolate the Control Box beforehand.

The method for adjusting the tension of the cable varies depending on the type of covering. Typically, you’ll find:

• Front tensioning: On both sides of the covering, at the front, you will find an M10 screw. Using a torque wrench, gently tighten this screw to a maximum of 7 Nm.
• Rear tensioning: The tension in some models is adjusted at the rear. Look for a plate with an M10 screw and, using a torque wrench, tighten it to a maximum of 7 Nm.

Important: If you have difficulty making the adjustment, we recommend you contact our nearest support centre (see question 9)

Using our map, you can locate your nearest authorized centre:

There are two options:

• Measure the length of the steel bar
• Submit the serial number of the covering (see question 2)

To request a spare part, please provide the following details:

• Company information: Company name, VAT number, Electronic Invoicing Code and address (only for new customers).
• Serial number of the covering: The serial number is generally shown on the covering itself (see question 2)
• Serial number of the control unit: The serial number is shown on the control unit (see question 12)

A jerky operation of the covering may be caused by any of several factors. We suggest you check the following steps. 

• Check the tension of the operating cable: Ensure that the cable is tensioned correctly and shows no structural damage. 

• Inspect the mechanical parts: Check visually for damages to the bows, the raising systems, the pads (the mechanics of the tarpaulin). 

• Check the correct operation of the controls: Test both the manual selector and the remote control. On the remote control, check the conditions of the batteries. 

• Reset the control unit: If you are still having problems, you may need to reset the control unit. Contact our service centre for technical support. 

• Check the sliding power: In some cases, you may need to adjust the sliding power of the cover. Please contact our support centre for a thorough check. 

The serial number is a 7-digit barcode.

This code can be found in either of two locations: On the inside of the green cover, or at the front of the control unit case.

The serial number of your covering consists of 1 letter and 5 digits. It is shown on an aluminium plate generally located on either of two places:

• On the second foot of the bow, on the driver’s side
• Near the electric motor or on the cab guard of the load body.
