ignition key off and set the aggregation of tractor and machine in a standstill position (Journal
of Laws No. 12/98 item 51.)
• Inspect bolts and other fasteners regularly. Do not operate with damaged or worn fasteners.
• Do not operate with damaged or worn fasteners. When the rubber guard shows signs of
ageing (e.g. microcracks over the surface), it should be replaced.
• Do not perform any repair works underneath the lifted machine’s assemblies, unless protected
against free falling (Journal of Laws No. 12/98 item 51.)
• Replace damaged or worn (aged 5 years or older) hydraulic hoses and other hydraulic parts as
recommended by the Manufacturer.
• Before any operation, check the condition of cutting knives. If blunt, rotate the knife by 1/3
turn (3 sharp cutting edges per a single knife can be achieved), or handle it for a recovery.
Damaged or worn blades must be replaced.

2.3 Residual risk
NOTE
Despite the fact, that SaMASZ company – Manufacturer of the tree stump
grinder takes responsibility for the machine's design and manufacturing, in
order to eliminate risk, certain elements of residual risk when operating the
grinder are unavoidable.

Operator's manual
TREE STUMP GRINDER
FP 20
- 8 -
NOTE
Present residual risk results mainly from erroneous actions taken by an
operator of the tree stump grinder and failure to follow rules provided herein.
NOTE
When describing residual risk, the tree stump grinder shall be considered a
machine, which until the moment of its production had been designed and
manufactured in accordance with the state-of-the-art as per its manufacture
date.
Danger of catching
This kind of risk is present when position of tree stump grinder is being changed, as a result
of operating near rotating parts.
Danger of cutting limbs off
Contact between cutting knives and body may lead to serious injuries, and in extreme cases
amputation of limbs or even death. Failure to pay enough attention when operating the machine
nearby unauthorized personnel may cause an accident.
Danger of wound
This risk is present when replacing working parts with sharp edges. During any maintenance
and repair works, always wear safety gloves.
Danger of kick
Kick is one of the most dangerous accidents which are likely when operating tree stump
grinder. It is described as uncontrolled, sudden and very quick motion of an object or part of it
being processed (splinter, knurl, etc.). Direct impact of the material against human body may cause,
depending on the material weight and size, as well as speed and the impact location, bruises,
injections, loss of an eye, teeth, or even death due to damage to organs and vast internal
haemorrhages.
Danger of causing irritation to skin and eyes
When connecting/disconnecting hydraulic hoses to/from tractor’s hydraulic connectors make
sure, that both the tractor’s and the extension arm’s hydraulics are pressure free. Otherwise, leak of
oil under pressure of approx. 20 MPa may occur. It also applies to damaged hoses. Therefore, when
operating the hydraulics, make sure to always wear protective gloves and eyewear. Regularly check
hydraulic hoses for leaks.
PROHIBITED ACTIONS
Bear in mind the following prohibited actions when operating tree stump
grinder.
• Do not remove impurities, make any adjustments or repairs when the grinder is operating.
• Never change the sequence of operation and maintenance works as specified herein.
• Never use the tree stump grinder, if it is not in operating condition.
