Residual Risk - SaMASZ KWT 550 Operator's Manual

Scotch tape shall never be used to repair damaged hydraulic hoses.
When connecting hydraulic hoses to tractor hydraulic connectors make sure, that either tractor or
machine hydraulics are pressure free.
When operating hydraulic unit, always wear protective gloves and eyewear. Leaking hydraulic oil
under pressure (16 MPa) may permeate through the skin and cause an infection. If experienced,
immediately visit a doctor.
Caution! Hydraulic assembly is under pressure! Hydraulic oil under pressure may permeate
through skin and cause serious injury, therefore skin and eyes should be protected in particular. In
case of injuries caused by a liquid under pressure, call a doctor immediately.
Hydraulic hoses can be connected to tractor's hydraulics, provided that both the tractor's and the
mower's hydraulic assemblies are not under pressure. To remove the pressure from the
hoses just simply restart the tractor's hydraulic valves several times, once the tractor is off.
When controlling for hydraulic assembly's malfunction and looking for oil leaks, it is forbidden to
touch any potential leaks until the entire assembly is under pressure.
Note! It is recommended to use hydraulic oil featuring oil purity class 9 - 10 in accordance
with NAS 1638.
When using hydraulic hoses:
Avoid stretching the hoses when operating.
Do not allow hydraulic hoses to get deflected.
Do not expose hydraulic hoses to contact with any sharp edges.
If damaged or worn, replace the hoses with new ones.
Useful life for hydraulic hoses is 5 years from their production date.

Residual risk

Despite the fact, that the manufacturer of the machine takes the responsibility for the machine
design and manufacturing, in order to eliminate hazard, certain risk when operating the machine is
unavoidable.
Major source of risk follows performance of these operations:
operation of machine by minors as well as not being familiarized with operator's manual,
operation of machine by persons under influence of alcohol or other abusive substances,
not keeping caution while transportation and shifting of machine during operation,
presence of persons and animals within the machine operation range,
performing operations related to servicing and adjustment with engine on.
1. Danger of catching
This kind of risk occurs when the machine position is changed, when operating near rotating
parts, operating without safety guards.
When operating, maintenance and regulation works are conducted protective gloves, footwear
and clothing with no loose parts, belts, etc. shall always be worn. Always comply with safety decals
placed on the machine.
2. Danger of wound
This kind of risk occurs when working parts with sharp edges are replaced. At any repair and
maintenance work safety gloves shall always be worn.
3. Danger of liquid ejection out of hydraulics
When connecting hydraulic hoses to and from the tractor hydraulic connectors make sure, that
either tractor or mower hydraulics are pressure free.
When operating hydraulic unit, always wear protective gloves and eyewear. Check
the hydraulics hoses regularly.
CAUTION:
Residual risk results from incorrect behavior of the machine operator.
