Hydraulic assembly
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 extension arm’s
and the ditch cleaner'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 dismounting the machine from the tractor, set the equipment aside, deflate the pressure
from hydraulics and turn tractor's engine 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 company SaMASZ Białystok – the manufacturer of the machine takes
responsibility for design and manufacturing of the rake, in order to eliminate dangerous situations,
certain risk during machine’s operation is unavoidable. Residual risk results from incorrect
behaviour of the ditch cleaner operator.
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 ditch cleaner during operation,
transport of persons remaining on the machine,
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 position of ditch cleaner is being changed, as a result of
operating near rotating parts.
During operation, maintenance and regulations always wear protective gloves, shoes and
clothes without loose parts, belts and so on. Always comply with safety decals placed on the
machine.
2.
Danger of injury and abrasion
This risk is present when replacing working parts with sharp edges, cleaning the machine,
removing the clogging and jams. During any maintenance and repair works, always wear safety
gloves.
3.
Danger of cutting limbs off
Contact of cutting knives with body may lead to serious injuries, and in extreme cases
amputation of limbs or even death. Not paying enough attention when operating the machine nearby
unauthorized personnel may cause an accident.
4.
Danger of throwing out.
Throwing out is one of the most dangerous phenomena, which are likely to occur when,
operating ditch cleaner. It is described as uncontrolled, sudden and very quick motion of an object
or part of it being treated (e.g. stones, etc.). If thrown material directly hits human body, it can,
depending of its weight, size, speed and impact point, cause: bruises, pinches, loss of eyes or teeth,
and even death as a result of damaging internal organs and vast internal haemorrhages.
