General maintenance
During offseason wash the equipment, repair any damaged paintwork, protect the
disc blades with oil, lubricate all grease fittings and store the equipment in a covered and
dry place, avoiding the direct contact of the disc blades with the soil.
The disc blades must be replaced as soon as they are providing a low yield, mainly
because of the reduction in its diameter, loss of cut and other damages that may occur
during the job.
After 24 working hours, the bolts on the equipment must be checked to see if they
are properly tightened. To assure a great performance and avoid wear and rupture, these
bolts must be tightened every so often.
Check wear occurence on all moving parts. Replace any part, if necessary.
Replace the missing or damaged safety decals. Marchesan supplies these decals,
upon request and indication of their respective serial numbers. The operator must know
the need and importance to keep the decals in the proper place and in good conditions.
The operator also have to know the need to follow the instructions, as the lack of safety
may increase the risk of accidents.
Hydraulic safety
Make sure that all components in the hydraulic system are kept in good
condition and are clean.
Inspect the hydraulic system periodically or when lack of power/defective
reposition of oil is being noticed. To do so, tight the connections that have leaks and
replace the hoses that are near its expiration date or the ones that are cut, with fissures or
dried out. Couple the hoses in a way that they will always work flexing but never twisting
or tractioning.
Do not attempt any makeshift repairs to the hydraulic lines, fittings or hoses by using
tape, clamps or cements. The hydraulic system operates under extremely high-pressure.
Such repairs will fail suddenly and create a hazardous and unsafe condition.
Wear proper hand and eye protection when searching for a high-pressure hydraulic
leak. Use a piece of wood or cardboard as a backstop instead of hands to isolate and
identify a leak.
If injured by a concentrated high-pressure stream of
hydraulic fluid, seek medical attention immediately. Serious
infection or toxic reaction can develop from hydraulic fluid
piercing the skin surface. If this doctor is not aware of this kind
of problem, ask for a reference or look for another one to find
the proper treatment.
Before applying pressure to the system, make sure all
components are tight and that lines, hoses and couplings are
not damaged.
