in gardens, school yards and parks without moving too much earth.
- The trench itself is up to 90 cm deep with a plain and clean unvaried profile
given by the cutting chain width. The machine is used for trenching in compact
soils with small stones in size up to 50 mm in one-man operation (operated by a
carrier driver).
- This machine is allowed to work only on flat and even terrain or up the
permissible limits of the used carrier as to its climbing ability.
- The given carrier must be fitted with a corresponding clamping plate. It
hydraulic system should provide minimum jib carrying capacity of 350 kg,
hydraulic oil pressure up to 10 MPa and oil flow of 70 l/min.

glass cullet, metal subjects, bars, wooden pieces, stony debris,
rubbish etc. or in concrete, bitumen and paved surfaces.
-
Avoid working with inclination exceeding the limit as allowed for the used
carrier,
-
It is forbidden to work if the used carrier could not provide required
parameters as to oil pressure and flow rate or if it is fitted with an incompatible
clamping plate.
-
It is forbidden to work if the carrier stands on unstable terrain, steep slopes and
close to trenches with risks of instability,
-
Avoid working on icy and frozen terrain (it applies also to frost-bound grassed
area).
