Truck or trailer transportation
Marchesan does not advise the equipment traffic on highways, because this
practice involves serious security risks in addition to being prohibited by the
current existing traffic law. The transportation for long distances should be done
on truck, trailer or others by following these safety guidelines:
• Use adequate ramps to load or unload the equipment. Do not make the loading
on ditch banks, it can cause a serious accident.
• When lifting with a hoist, use the appropriate points to lift.
• Fasten the moving parts that may get loose and cause accidents.
• Underpin the equipment appropriately.
• Use chock blocks and safety chains to secure the equipment to the truck or trailer
during the transport.
• After 8 to 10 km transporting, please inspect the load condition. Repeat this
procedure every 80 to 100 km. Give more attention when transporting the
equipment on rough roads, slopes and other adverse conditions.
• Always be careful with the load height, especially when passing under electrical
power lines, bridges and others.
• Check all laws and regulations regarding the height limits and load width while
transporting the equipment on truck or trailer. If necessary use banners, lights
and other devices in order to give adequate warning to the other drivers.

IMPORTANT Check the correct side of the bearings and spacer spools according
to the concavity of the disc blades.
• Place the external lock (A) along with the axis (B). (Figure on page 14).
• Place the disc blades (C), bearings (D) and spacer spools (E), following the
instructions on page 12.
• Fit the internal lock (F), the lock nut (G) and the nuts (H) passing 5 mm from the
axis face.
• Now, use the wrench (A) from page 11 and tight the gangs to get maximum torque.
• To tighten, the gangs must remain underpinned with a piece of wood or another
object, preventing it from moving. (Figure on page 14).

Working preparation
Tractor preparation
The following instructions must be carefully observed in order to get the best work
performance.
The addition of ballast water in the tires and a set of weights on the front part and rear
wheels of the tractor are the most used ways to increase the soil traction and give greater
stability to the tractor. Check if the tractor is in full conditions before working.
Harrow preparation
Couple the hitch (A) to the traction
bar and fasten it using the axis (B) and
r-clip.
The traction bar must remain fixed
during working.
Check the condition of all parts, retightening nuts and bolts, especially from the disc
gangs. These will damage the axis and other components, if they work loose.
Lubricate all grease fittings appropriately. (See lubrication instructions on page 23).
