3.3 Maximum values of noise and vibrations as measured by AO -
206 SZZPLS Praha.
DS-520
Time averaged emission level of acoustic load at operator’s site L
pAeq,T
= 83 dB (measured to
ČSN EN ISO 112
01).
Guaranteed level of machine’s acoustic output L
WA
= 100 dB (according to NV No.9/2002
Gaz.)
Weighted effective value of accelerated vibrations transferred onto operator’s hands (vector
sum of rectilinear vibrations on individual axes) is 6,4 m.sec
-2
(testing method according to
standard ČSN EN 1033).

4 Machine use, technical specification and technical
description.
4.1 Machine use.
Manually pushed drum mower DS-520 (DS-520H) Líza is designed and manufactured
according to the latest knowledge of small gardening machinery.
The mower is meant for cutting low thin-stalked meadow swards on flat, well-kept
surfaces with no terrain irregularities. Maximum sward height is 30 cm. The mower is not
designed either for soft landscaping of grass stands or for cutting swards arisen from self-
seeding.
