Adjustments and operations
Operations - Important points
• Retighten nuts and bolts after the first day of work and check the conditions of
all pins and cotter pins. Then, retighten every 24 operating hours.
• Special attention should be given to the disc gangs, retightening daily during
the first week of use. Then, tighten periodically.
• Carefully observe the lubrication intervals.
• The tire inflation must be done with the aid of a contention device (tire inflation
cage).
• The tire inflation is important; keep the inflation according to the 'tires inflation'
pages
.
• Choose a gear that allows the tractor to maintain certain power reserve, ensuring
against unforeseen efforts.
• Always carry out the operations on a careful and controlled manner.
• Speed is relative to the tractor gear and can only be determined by local
conditions. We adopted an average 5
to 7 km/h
, which is not advisable to
overcome to maintain service efficiency and avoid possible damages to the
equipment.
• Before maneuvering, activate the hydraulic cylinder gradually to lift the disc
gangs.
• The harrowed soil is always on the left hand side of the operator.
• Remove pieces of wood or any object that may attach in the disc blades.
• The harrow activation to open or close the disc gangs must be done gradually,
while the tractor is moving.
• Do not check any leaks with your bare hands, because the high pressure can
cause injury. Use cardboard or other suitable object.
• Only pull the harrow using a tractor with enough power.
• Never maneuver to the right side during operation, because the angle formed
by the gangs start to transmit great effort to the equipment, overloading traction
components.
• Relieve the control valve pressure before disconnecting the quick couplers and
when doing any verification in the hydraulic cylinder.
• When working over compacted soils, the disc blades penetration may be harder
and the depth may be minimum, leading to an unsatisfactory operation. On these
cases, we recommend using an equipment that is more suitable to this job.
• The tractor drawbar must remain loose during working and fixed during
transportation
.
• During working or transportation, the presence of passengers on the tractor or
equipment is not allowed.
• As previously mentioned these disk harrows have several settings, but only the
local conditions can determine their best adjustment.
