Section 2 - Corn Head Safety
Since the equipment - corn head - named "Drago GT" has features that involve a significant degree of
dangerousness due to the nature of the harvesting system, the operator and any people standing within the
operating range of the equipment must take into utmost account the recommendations described in this
manual, as well as those included in the Operator's Manual of the combine.
Before working with the corn head read carefully and thoroughly this manual, the manual of the
PTO drive shafts supplied with the equipment and the Operator's Manual of the combine.
Through this manual you will acquire all the information regarding the general characteristics of the
equipment needed to train personnel on safe handling.
Important: Please note the decals placed in visible positions on the equipment that detect
dangerous items and behaviors that are recommended for your safety (danger-warning–caution)
followed by specific instructions. These recommendations are intended to achieve the protection of
the personal safety of the operator and those who work with you. Before using the equipment it is
necessary to read and understand these contents.
Based on the activities you are going to perform while using this equipment, wear the appropriate
PPE. In particular, the following are recommended:

AVOID BEING CAUGHT:
To avoid being caught:
-No activity or operation must be conducted with staff in the vicinity of the head when it is
operating.
-The personnel should not wear clothing unsuitable for work such as belts
or parts of loose or fluttering fabric.
-It is strictly forbidden to attempt to intervene with temporary non-
dedicated tools during normal operation of the machine or to resolve
anomalies.
-Any operation, also unclogging the head, must be carried out when the
machine is stopped and powered down as described in the following
chapters.
Failure to follow instructions could be fatal since the harvesting system is
aggressive in nature.
When being caught, you must:
-Secure the machine by removing and by disconnecting from any source of energy;
-as appropriate, disassemble and remove the parts that cause entanglement or manually operate
the rotation of the moving parts in the reverse, making sure, beforehand, to avoid further injury.

2.3 – Operating Safety Precautions
Before operating this corn head, thoroughly read and understand this manual, as well as your Combine
Operators Manual. Make all information available contained therein to those working with you and/or for
you.
1) Before start-up, check corn head for operational and traffic safety tips.
2) Ensure everyone is clear of the combine before starting.
3) Pay attention to all local safety regulations in addition to the recommendations made in this
operator’s manual.
4) Before starting work, get familiar with all devices and their functions.
5) The combine should always be equipped with sufficient rear axle weight for safe
operation. Under
some field conditions, more weight may be required at the rear axle for adequate stability. See
Table 9.1 for corn head weight and the Combine Operators Manual for required ballasting. For
any corn heads not listed in Table 9.1 call OLIMAC SRL.
6) Pay attention to permissible axle loads and total weights.
7) The mounted corn head influences speed, steering and braking capability – observe sufficient
steering and braking capability.
8) Only allow passengers on the combine for brief periods for training or observation only.
9) Keep all safety shields in place. Failure to do so may result in serious injury or death.
10) Never wear loose fitting clothing that might catch on moving parts while working around the corn head or
combine.

2.4 – Maintenance Safety Precautions
Before performing any repairs or maintenance on the combine or corn head:
1) Lower the corn head to the ground or raise the corn head completely and lower the feeder
house lift cylinder safety stops.
2) Engage the parking brake.
3) Shut off the combine engine and remove key.
4) Disconnect corn head drive shafts.
5) Hang a “Do Not Operate” tag in the operator’s station.
6) If the corn head should become plugged, stop the combine and engine before
removing the
obstruction. Failure to do so could result in serious injury or death.
Before performing any lubrication or adjustment to the combine or corn head:
1) Lower the corn head to the ground or raise the corn head completely and lower
the cylinder
safety stops.
2) Engage the parking brake.
3) Shut off the combine engine and remove the key.
4) Disconnect corn head drive shafts.
5) Hang a “Do Not Operate” tag in the operator’s station.
Avoid High Pressure Fluids
1) Lower the corn head to the ground or raise the corn head completely and lower
the cylinder
safety stops.
2) Always release all hydraulic pressure prior to opening the system. Failure to do so may result
in a hydraulic injection injury.
3) Inspect all hoses for damage or wear at least once per season. If any hoses show signs of
wear or failure replace immediately.
4) To inspect for leaks use a piece of card board, never use hands. If an accident occurs, contact a
hand surgeon or specialist familiar with injection injuries immediately. Do not contact a general
practitioner. Any fluid injected into the skin must be surgically removed within a few hours or
gangrene may result.

Do Not Feed Material by Hand
To avoid entanglement, do not feed crop material into the corn head by hand, or
attempt to manually
unplug the corn head while it is running. The stalk rollers can feed the crop material in faster than you can
release your grip on the material.
Avoid Hearing Loss
Prolonged exposure to loud noise can cause hearing impairment or loss of hearing. Wear a suitable
protective hearing device such as earmuffs or earplugs to guard against objectionable or
uncomfortable loud noise.
Avoid Rotating Components
Pay attention to the corn head when in motion. Stalk rollers of the corn head, etc. cannot be
completely shielded due to their movement.Always stay clear of these
moving parts during
operation.
Remove paint before welding or heating to avoid toxic fumes and dust.
1)
Disconnect all batteries prior to welding.
2)
Work only in well-ventilated areas.
3)
Remove paint to a minimum distance of 3” (76mm) away from the area to be effected by heating.
4)
If you must sand or grind, avoid breathing the dust. Wear an approved respirator.
5)
If using solvent or paint stripper, remove the stripper with soap and water before welding.
Never use chlorinated brake cleaner before welding.
6)
Remove all aerosols, combustible fluids and any other flammable material from the work area.
Allow fumes to disperse at least 15 minutes before welding or heating.
7)
Keep all hydraulic lines and oil reservoirs away from the work area while using heat. Failure to
do so can rupture lines causing pressurized fluids to ignite.
8)
Dispose of paint and solvents safely.
