Residual Risk - SaMASZ P4-420 Operator's Manual

In case of injury caused by a liquid under pressure, call a doctor immediately.
Hydraulic hoses can be connected to the tractor's hydraulics provided that both the tractor's and
the tedder's hydraulic assemblies are not under pressure. To remove the pressure from the
hoses, start the tractor's hydraulic valves several times with the tractor off.
When looking for oil leaks, do so safely. Use a cardboard card. Do not touch any potential
leaks until the entire hydraulic assembly has been relieved of pressure.
It is recommended that the hydraulic oil used should not exceed 10 oil purity class 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.

4.8. Residual risk

Despite the fact that SaMASZ, the manufacturer of the tedder, has taken great care in the
design and manufacturing of the tedder, certain risks during tedder operation and maintenance are
unavoidable. A major source of risk that could result in serious injury or death can occur during the
performance of these operations.
Major source of risk follows performance of these operations:
operation of tedder by minors,
operation by individuals who have not read the operator's manual and safety labels,
operation of tedder by persons under influence of alcohol or other substances,
not being cautious during transportation and moving tedder during operation,
transport of persons who are on the machine,
presence of persons and animals within the tedder operation range,
performing servicing and machine adjustments with the engine on.
1. Danger of machine entanglement
This risk occurs when (1) changing position of a tedder, (2) operating near rotating parts, and
(3) working without safety guards. During operation, maintenance and adjustment, always wear
protective gloves, shoes and clothes without loose parts, belts and so on. Always comply with safety
labels placed on the tedder.
2. Danger of cutting injury, abrasion and damage of skin
This risk occurs during replacement of working parts with sharp edges, cleaning the machine
and removal of any clogging and seizure. During any maintenance work, always use safety gloves.
3. Danger of injury from liquid ejection out of hydraulic system
During connection of hydraulic hoses to hydraulic connectors, be sure that tractor's or
tedder's hydraulic system is not under pressure. Regularly check hydraulic hoses for leaks.
NOTE:
Residual risk always results from incorrect behavior of tedder's operator.
