properly and safely perfor m the job . Only use
accessories and attac hments appro v ed b y the
man ufacturer .
•W ear appropriate clothing including hard hat,
safety glasses and hearing protection. Long
hair , loose clothing or jew elr y ma y g et tangled
in mo ving par ts .
•Inspect the area where the equipment is to be
used and remo v e all objects suc h as roc ks , to ys
and wire whic h can be thro wn b y the mac hine .
•Use extra care when handling g asoline and
other fuels . T hey are flammable and v apors
are explosi v e .
– Use only an appro v ed container
– Nev er refuel or drain the mac hine indoors .
– Nev er remo v e g as cap or add fuel with
engine r unning . Allo w engine to cool
before refueling . Do not smok e .
•Chec k that operator’ s presence controls ,
safety switc hes and shields are attac hed and
functioning properly . Do not operate unless
they are functioning properly .
Operation

that c hang e the operating angle , as rough
ter rain could o v er tur n the mac hine .
•A v oid sudden star ts when mo wing uphill
because the mo w er ma y tip bac kw ards .
•Be a w are that loss of traction ma y occur g oing
do wnhill. W eight transfer to the front wheels

blades and proceed slo wly off the slope .
•F ollo w the man ufacturer’ s recommendations
for wheel w eights or counterw eights to
impro v e stability .
•Use extreme care with g rass catc hers or other
attac hments . T hese can c hang e the stability of
