3. Safety instructions
3.1. Residual risks
Read this operating and maintenance manual thoroughly before operating
the machine and follow the instructions given. 
Crushing hazard when connecting and disconnecting the seed and
fertiliser drill. Safety distance 5  m. Be extremely careful if someone else is
near the seed and fertiliser drill and tractor giving instructions on
connecting and disconnecting. 
Crushing, cutting and impact hazard when lifting and lowering the centre
markers. When lifting and lowering the markers, make sure nobody is in
the vicinity. Safety distance is 5 m when the markers are up and the
machine is running. Before performing the calibration test, ensure that the
marker ball valves are closed.
Crushing hazard when the accessories are being adjusted. Before adjusting
the accessories, make sure that the tractor is turned off, the key is removed
from the ignition and the parking brake is engaged.
There is a crushing and cutting hazard in the machine’s transmission when
performing servicing and maintenance. Before servicing, make sure that
power is switched off in the tractor, the key is removed from the ignition
and the parking brake is engaged.
Crushing hazard when lifting and lowering the seed and fertiliser drill.
When lifting and lowering the machine, make sure nobody is in its vicinity.
Safety distance 5 m. 
There is a crushing hazard when performing servicing and maintenance.
Before servicing, ensure that stoppers have been placed in the stems of the
cylinder and that the machine has been supported from underneath with a
block or similar. Never go under the machine that is not propped up.
Hydraulic hoses under pressure may release a life-threatening jet of liquid.
High-pressure liquid may also cause a crushing, cutting or impact hazard.
The hydraulic system must be depressurised before pressure hoses are
handled, connected or disconnected. Depressurise the hydraulic system
and disconnect the hoses before maintenance work.
Never touch the hydraulic cylinders, hoses and hydraulic connectors when
the cylinders are in operation. 
Falling hazard when performing work on the platform. Be careful when
performing work on the platform. Accessing the steps of the platform is
allowed only when the machine is lowered.
Operation and maintenance
manual

Falling hazard. Staying on top of the machine, wheels and sensors is always
prohibited.
Before moving and servicing, ensure that the markers have settled in the
transport position and that their ball valves are closed.
Before performing a calibration test, ensure that the tractor’s parking brake
is engaged and the ball valves are closed.
Crushing hazard when lifting the seed and fertiliser drill from a bed using a hoist.
Safety distance 10 m. Exercise special caution. 
Crushing or cutting hazard during the installation of the drawbar and front
equipment. Exercise special caution. 
Crushing or cutting hazard during the installation of the rear harrow, markers,
front platform or tow bar cylinder. Exercise special caution. 
Before moving, ensure that the tractor’s hitch is locked.
Crushing and cutting hazard when removing the wheels. Exercise caution when
handling the wheels. 
Depressurise the hydraulic system, disconnect the hoses and tractor's electrical
connections and let the machine cool off before servicing. 
Avoid breathing seed dressing dust and fertiliser dust when lling the hopper. The
seed dressing causes a serious health risk. Read the material safety data sheet of
the dressing agent and fertiliser and pay attention to their warnings. 
Never go under a lifted load when lling the hopper. 
Make sure that nobody is on top of the seed and fertiliser drill or inside the hopper
when lling the hopper. 
Wear protective gloves when handling oil or grease and when connecting and
disconnecting hydraulic components. Avoid skin contact with oil and grease to
prevent skin irritation and damage.

3.2. Symbols used in the operating manual
DANGER warns of a dangerous situation which may lead to death or serious
physical injury. 
NOTE  warns of a dangerous situation which may lead to damage to the
equipment. 
ADVICE contains useful tips, advice and information in the instructions e.g. on
tightening torques, adjusting values, liquid quantities and special tools. 
DANGER
When connecting and disconnecting hydraulic hoses and electric wires, ensure that the
tractor is turned off and the key is removed from the ignition. 
DANGER
Never adjust or clean a moving seed and fertiliser drill.
DANGER
Never stay on top of the seed and fertiliser drill or within its operating area during
operation. Safety distance 5  m.
DANGER
Inspect the condition of the seed and fertiliser drill at least visually before moving or
operating it. Items to be inspected include tyre pressure, machine cleanliness and the
tightness of the bolts of the towing device. 
DANGER
Before seeding, make sure that the machine is in working order. Make sure that the
hoses are intact and have no leaks. Make sure that the coulters and mechanics are
intact. Specically ensure that all the pins are in place. 
DANGER
When transporting the seed and fertiliser drill on public roads, exercise caution and
observe all road traffic regulations, as well as specic regulations concerning slow-
moving vehicles. 
DANGER
Before moving the tractor, check that the slow-vehicle triangle is visible and tractor
lights are lit and visible. Keep the triangle and lights clean, because they have a
considerable impact on the vehicle's traffic safety. 
DANGER
The maximum allowed transportation speed of the seed and fertiliser drill is 40  km/h on
a road that is in good condition and even. The maximum allowed transportation speed
of the seed and fertiliser drill is 25 km/h on damaged roads.
DANGER
When replacing hydraulic system components and conductors, only use spare parts
with sufficient pressure resistance.

DANGER
Never use oil or lubrication grease to clean skin. These substances may contain small
metal particles, which cause irritation of the skin or cuts. Follow the handling
instructions and safety regulations of the lubricant manufacturers. Synthetic oils are
often corrosive and cause strong irritation of the skin. Contact a doctor, if oil or grease
causes injuries. 
DANGER
Never spray water directly on electric equipment. 
CAUTION
Before servicing, ensure that the machine lifting ball valve is closed and the cylinders
are equipped with stoppers. 
CAUTION
Use original spare parts of the machine whenever servicing and repairing the seed and
fertiliser drill. Using generic parts invalidates the warranty. 
CAUTION
Collect oil waste and dispose of it appropriately in accordance with national
regulations.
CAUTION
If oil is spilled on the ground, absorb it with absorption material, such as turf, to prevent
the oil spill from spreading. Handle the absorption material in accordance with
regulations. 
CAUTION
Clean the machine whenever you change fertiliser or seed types. 
CAUTION
If the machine will be unused overnight or over a long rain season, empty its fertiliser
hopper in advance and clean the roller grooves of the feeder by adjusting feed quantity
from one extreme position to the other. Otherwise, the fertiliser may dissolve and clog
the feeders. 
CAUTION
Before using a detergent, make sure it is appropriate for washing a seed and fertiliser
drill. Follow the safety and operating instructions of the detergent manufacturer.
