Safety
Safe Operation Practices
for Ride-on (riding) Rotary
Lawnmower Machines
T his mac hine meets or ex ceeds European
Standards in effect at the time of production.
Ho w ev er , improper use or maintenance b y the
operator or o wner can result in injur y . T o reduce
the potential for injur y , comply with these safety
instr uctions and alw a ys pa y attention to the
safety aler t symbol, whic h means CA UTION ,
W ARNING , or D ANGER -“personal safety
instr uction. F ailure to comply with the instr uction
ma y result in personal injur y or death.
Safe Operating Practices
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:
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;
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 .
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 .
4
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 .
W atc h out for traffic when crossing or near
roadw a ys .
Stop the blades rotating before crossing
surfaces other than g rass .
W hen using any attac hments , nev er direct
disc harg e of material to w ard b ystanders
nor allo w any one near the mac hine while in
operation.
Nev er operate the mac hine with damag ed
guards or without safety protecti v e devices in
place .
Do not c hang e the engine g o v er nor settings or
o v erspeed the engine . Operating the engine
at ex cessi v e speed can increase the hazard of
personal injur y .
Before lea ving the operator’ s position:
diseng ag e the po w er tak e-off and lo w er the
attac hments;
c hang e into neutral and set the parking
brak e;
stop the engine and remo v e the k ey .
Diseng ag e dri v e to attac hments , stop the
engine , and disconnect the spark plug wire(s)
or remo v e the ignition k ey
before clearing bloc kag es or unclog ging
c hute;
before c hec king, cleaning or w orking on
the la wnmo w er;
after striking a foreign object. Inspect
the la wnmo w er for damag e and mak e
re pairs before restar ting and operating the
equipment;
if the mac hine star ts to vibrate abnor mally
(c hec k immediately).
Diseng ag e dri v e to attac hments when
transpor ting or not in use .
Stop the engine and diseng ag e dri v e to
attac hment
before refuelling;
before remo ving the g rass catc her;
before making height adjustment unless
adjustment can be made from the operator’ s
position.
R educe the throttle setting during engine
r un-out and, if the engine is pro vided with
a shut-off v alv e , tur n the fuel off at the
conclusion of mo wing .
Maintenance and Storage
K ee p all n uts , bolts and screws tight to be sure
the equipment is in safe w orking condition.
Nev er store the equipment with fuel in the
tank inside a building where fumes can reac h
an open flame or spark.
Allo w the engine to cool before storing in any
enclosure .

Recommended Gasoline
Use UNLEADED R egular Gasoline suitable
for automoti v e use (87 pump octane minim um).
Leaded regular g asoline ma y be used if unleaded
regular is not a v ailable .
Important: Nev er use methanol, gasoline
containing methanol, or gasohol containing
mor e than 10% ethanol because the fuel
system could be dama ged. Do not mix oil
with gasoline.
In cer tain conditions, gasoline is extr emel y
flamma ble and highl y explosi v e. A fir e or
explosion fr om gasoline can bur n y ou and
other s and can dama ge pr oper ty .
Fill the fuel tank outdoor s, in an open
ar ea, when the engine is cold. W ipe up
an y gasoline that spills.
Nev er fill the fuel tank inside an enclosed
trailer .
Do not fill the fuel tank completel y full.
Add gasoline to the fuel tank until the
lev el is 1/4 to 1/2 inch (6 to 13 mm)
belo w the bottom of the filler neck. T his
empty space in the tank allo ws gasoline
to expand.
Nev er smok e when handling gasoline,
and stay a w ay fr om an open flame or
wher e gasoline fumes may be ignited by
a spar k.
Stor e gasoline in an appr o v ed container
and k eep it out of the r each of childr en.
Nev er buy mor e than a 30-day suppl y of
gasoline.
Do not operate without entir e exhaust
system in place and in pr oper w or king
condition.

In cer tain conditions during fueling , static
electricity can be r eleased causing a spar k
which can ignite the gasoline v apor s. A fir e
or explosion fr om gasoline can bur n y ou and
other s and can dama ge pr oper ty .
Al w ays place gasoline container s on the
g r ound a w ay fr om y our v ehicle bef or e
filling .
Do not fill gasoline container s inside
a v ehicle or on a tr uck or trailer bed
because interior car pets or plastic tr uck
bed liner s may insulate the container and
slo w the loss of an y static charge.
W hen practical, r emo v e gas-po w er ed
equipment fr om the tr uck or trailer and
r efuel the equipment with its wheels on
the g r ound.
If this is not possible, then r efuel such
equipment on a tr uck or trailer fr om a
por ta ble container , rather than fr om a
gasoline dispenser nozzle.
If a gasoline dispenser nozzle must be
used, k eep the nozzle in contact with the
rim of the fuel tank or container opening
at all times until fueling is complete.
Gasoline is har mful or f atal if s w allo w ed.
Long-ter m exposur e to v apor s can cause
serious injur y and illness.
A v oid pr olonged br eathing of v apor s.

Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the mac hine to
pro vide the follo wing benefits:
K ee ps g asoline fresh during storag e of 90 da ys
or less . F or long er storag e it is recommended
that the fuel tank be drained.
Cleans the engine while it r uns
Eliminates gum-lik e v ar nish buildup in the fuel
system, whic h causes hard star ting
Important: Do not use fuel additi v es
containing methanol or ethanol.
Add the cor rect amount of g as
stabilizer/conditioner to the g as .
Note: A fuel stabilizer/conditioner is most
effecti v e when mix ed with fresh g asoline . T o
minimize the c hance of v ar nish de posits in the fuel
system, use fuel stabilizer at all times .
Filling the Fuel Tank
1. Shut the engine off and set the motion controls
to the park position.
2. Clean around the fuel tank cap and remo v e
the cap . Add unleaded regular g asoline to the
fuel tank until the lev el is 1/4 to 1/2 inc h
(6 to 13 mm) belo w the bottom of the filler
nec k. T his space in the tank allo ws g asoline to
expand. Do not fill the fuel tank completely
full.
3. Install the fuel tank cap securely . Wipe up any
g asoline that ma y ha v e spilled.

Operating Tips
Fast Throttle Setting
F or best mo wing and maxim um air circulation,
operate the engine at the F ast position. Air is
required to thoroughly cut g rass clippings , so
do not set the height-of-cut so lo w as to totally
sur round the mo w er b y uncut g rass . Alw a ys tr y to
ha v e one side of the mo w er free from uncut g rass ,
whic h allo ws air to be dra wn into the mo w er .
Cutting a Lawn for the First Time
Cut g rass slightly long er than nor mal to ensure
that the cutting height of the mo w er does not
scalp any unev en g round. Ho w ev er , the cutting
height used in the past is g enerally the best one to
use . W hen cutting g rass long er than six inc hes tall,
y ou ma y w ant to cut the la wn twice to ensure an
acce ptable quality of cut.
