•These machines are intended for agricultural use only. Any use outside of this purpose shall
be considered as not intended use. Learn how to use your machine correctly and carefully!
•The machine may be dangerous when driven by not authorized individual or when operated
carelessly.
1.2. Health and safety regulations
•Before each start, check whether the tractor and machine are safe for road traffic and
operation!
•The tractor working with the machine must be equipped with the weights on the front axis!
Balance of the tractor with the attached machine, its steerability and braking ability must
always be kept.
•When connecting and disconnecting the machine to/from the tractor, its lifting and lowering
on the hydraulic lift of the tractor, setting the machine in the transport and working positions
and on the headlands, ensure that no bystanders and in particular children are present in the
vicinity of the machine. Perform these operations slowly, without sudden jerks!
•Never stay between the tractor and cultivator when the tractor’s engine is running!
•The machine may only be operated, maintained and repaired by the personnel who know its
construction and are aware of the existing hazards!
•There are some places where crushing or cutting may occur on the parts actuated by the
forces other than the human force (e.g. the hydraulic system). When connecting the
hydraulic hoses to the hydraulic system of the tractor, always ensure that the hydraulics is
depressurized! Check positions of the control levers of the tractor hydraulic system. Only
actuate the hydraulically operated attachments when there is nobody present within their
range of operation! Check the hydraulic hoses on regular basis and replace them with new

•Adjustment of the braking force consists of decreasing the idle stroke of the cylinder. Begin
from depressurizing the braking system, and then disconnect the lever (B) from the yoke (C)
and unscrew the yoke (B) towards the lever (C). Reconnect the system.
•If the further adjustment of the yoke (C) is impossible, replace the position of the lever (B) on
the splined connection of the brake expander (A). You can do this step only once – if the
braking force continue to drop, begin adjustment from verification condition of the brake
linings.
CAUTION! THE SYSTEM IS PRESSURIZED!
•Depressurize the system before beginning any work on
it.
•Daily maintenance consists of checking the system for
leaks and visual inspection of air lines.
Fig. 17: Dewatering of the system
•Replace any damaged components with new ones
immediately.
•Dewater the air system at least twice a year and in particular before the winter. In order to
do this, remove the plug (1) in the bottom part of the air tank (2). Replace the plug and check
the system for leaks after dewatering.
•Clean the line filter as required, however not less frequently than once a year.
•Add an antifreeze agent for the safe operation of valves in the compressed air system. Follow
the tractor manufacturer’s recommendations.
