T he follo wing instr uctions are from the CEN standard EN 836:1997.
T his product is capable of amputating hands and feet and thro wing objects . Alw a ys follo w all safety instr uctions to a v oid serious injur y or death.
Training
R ead the instr uctions carefully . Be familiar with the controls and the proper use of the equipment.
Nev er allo w c hildren or people unfamiliar with these instr uctions to use the la wnmo w er . Local regulations can restrict the ag e of the operator .
Nev er mo w while people , especially c hildren, or pets are nearb y .
K ee p in mind that the operator or user is responsible for accidents or hazards occur ring to other people or their proper ty .
Do not car r y passeng ers .
All dri v ers should seek and obtain professional
and practical instr uction. Suc h instr uction should emphasize:
being dri v en too fast;
inadequate braking;
the type of mac hine is unsuitable for its
task;
lac k of a w areness of the effect of
g round conditions , especially slopes;
incor rect hitc hing and load distribution.
Preparation
W hile mo wing, alw a ys w ear substantial footw ear and long trousers . Do not operate the equipment when barefoot or w earing open sandals .
T horoughly inspect the area where the equipment is to be used and remo v e all objects whic h ma y be thro wn b y the mac hine .
W ar ning-Fuel is highly flammable .
Store fuel in containers specifically designed
for this pur pose .
R efuel outdoors only and do not smok e
while refuelling .
Add fuel before star ting the engine . Nev er
remo v e the cap of the fuel tank or add fuel while the engine is r unning or when the engine is hot.
If fuel is spilled, do not attempt to star t the
engine but mo v e the mac hine a w a y from the area of spillag e and a v oid creating any source of ignition until fuel v apors ha v e dissipated.
R e place all fuel tanks and container caps
securely .
R e place faulty silencers .
Before using, alw a ys visually inspect to see that
the blades , blade bolts and cutter assembly are not w or n or damag ed. R e place w or n or damag ed blades and bolts in sets to preser v e balance .
the need for care and concentration when
w orking with ride-on mac hines;
control of a ride-on mac hine sliding on a
slope will not be reg ained b y the application of the brak e . T he main reasons for loss of control are:
insufficient wheel g rip;
On m ulti-bladed mac hines , tak e care as rotating one blade can cause other blades to rotate .
Operation
Be aler t, slo w do wn and use caution when making tur ns . Look behind and to the side before c hanging directions .

Do not operate the engine in a confined space where dang erous carbon mono xide fumes can collect.
Mo w only in da ylight or in g ood ar tificial light.
Before attempting to star t the engine ,
diseng ag e all blade attac hment clutc hes and shift into neutral.
Do not use on slopes of more than 15 deg rees .
R emember there is no suc h thing as a safe
slope . T ra v el on g rass slopes requires par ticular care . T o guard ag ainst o v er tur ning:
do not stop or star t suddenly when g oing
up or do wnhill;
use lo w speeds on slopes and during tight
tur ns;
sta y aler t for humps and hollo ws and other
hidden hazards;
Use care when pulling loads .
Use only appro v ed dra wbar hitc h points .
Limit loads to those y ou can safely control.
Do not tur n shar ply . Use care when
rev ersing .
