POTENTIAL HAZARD
♦ Engine exhaust contains carbon monoxide, which is
an odorless deadly poison.
WHAT CAN HAPPEN
♦ Carbon monoxide can kill you and is also known to the
State of California t o cause birth defects.
HOW TO AVOID THE HAZARD
♦ Do not run engine indoors or in a small confined area
where dangerous carbon monoxide fumes can collect.
WARNING
POTENTIAL HAZARD
♦ In certain conditions gasoline is extremely flammable
and highly explosive.
WHAT CAN HAPPEN
♦ A fire or explosion from gasoline can bur n you, ot hers,
and cause property damage.
HOW TO AVOID THE HAZARD
♦ DO NOT smoke while refueling , and stay away from
an open flame or where gasoline fumes m ay be ignited
by spark.
♦ Refuel only in a well ventilated area, or refuel
outdoors.
♦ Store gasoline in an approved container and keep it
out of the reach of children.
♦ Add fuel before start ing the engine. Never remove the
cap of the fuel tank or add fuel when engine is running
or when the engine is hot.
♦ Never fill the fuel tank so that the gasoline level rises
above a level that is 1/2” below the bottom of the filler
neck to allow for gasoline expansion and prevent fuel
spillage.
♦ If fuel is spilled, DO NOT attempt to start the engine.
Move away from the area of the spill and avoid
creating any source of ignition unt il fuel vapors have
dissipated.
DANGER

POTENTIAL HAZARD
♦ In certain conditions gasoline is extremely flammable
and highly explosive.
WHAT CAN HAPPEN
♦ A static charge can ignite g asoline vapors. A fire or
explosion from gasoline can burn you, others, and
cause property damage.
HOW TO AVOID THE HAZARD
♦ Purchase and store gasoline only in an approved
container.
♦ Always place gasoline containers on the ground away
from your vehicle before f illing.
♦ Do not fill gasoline containers inside a vehicle or on a
truck or trailer bed because inter ior car pets or plastic
truck bed liners may insulate the container and slow
the loss of any static charge.
♦ When practical, r emove gas-powered equipment from
the truck or trailer and refuel the equipment with its
wheels on the ground.
♦ If this is not possible, then refuel such equipment on a
truck or trailer from a portable container, rather t han
from a gasoline dispenser nozzle.
♦ If a gasoline dispenser nozzle must be used, keep the
nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete.
DANGER
1.4 OPERATION
Although hazard control and accident prevention parti al l y are dependent upon
the design and configuration of the equipment, these factors are also dependent
upon the awareness, concern, prudence and proper training of the personnel
involved in the operation, transport, mai nt enance and st orage of the equipment.
It is essential that all Operator Safety Mechanisms be connected and in operating
condition prior to use for mowing.
1.4.1 Give complete, undivided attent ion t o t he job at hand.
1.4.2 Mow only in daylight or good artificial light.
NOT
operate the mower when children or others are in the area.
1.4.3 When feasible, avoid operating the eq uipm ent in wet grass.
1.4.4 Use
EXTREME
traction and/or tipover could occur. Drive slower on slopes
slopes greater than 15 degrees. Watch for dit ches, holes, rocks, dips, and
rises, which change the operating angle. Keep away from drop-offs and steep
banks. Avoid sudden starts when mowing uphill - mower may tip backwards.
Loss of traction may occur going downhill - weight t r ansfer to the front wheels
may cause drive wheels to slip and cause loss of braking.
slopes when grass is wet - slippery conditions affect steering and reduce
traction and braking. T he oper ator is responsible for safe operation on slopes.

1.4.17 If jump starting is required:
a) connect the positive (+) power cable from the posit ive post on t he booster
battery to the positive terminal post on the starter solenoid switch (this
post has the positive battery cable attached to it).
b) connect the negative or ground cable (-) from the negative post on the
booster battery to any engine deck gr ound, pr eferably the engine block
as far away from the battery as possible.
c) disconnect battery cables in the reverse order after start ing .
1.5 MAINTENANCE AND STORAGE
1.5.1 For engine maint enance, follow the engine manufacturer’s recomm endations
precisely as stated in the engine manual.

1.5.3 Keep engine and engine area free from accumulation of grass, leaves,
excessive grease or oil and other debris which can accumulate in these areas.
These materials can become flammable and m ay result in a fire.
1.5.4 Store f uel in a container specifically designed for this purpose in a cool, dry
place.
1.5.5 Keep the mower and fuel container in locked storage to prevent children f r om
playing or tampering with them.
1.5.6 Gasoline powered equipment or fuel containers should not be stored in a
basement or any enclosed area, where open pilot lights or heat appliances are
present.
1.5.7 Maximum mowing results and safet y can only be achieved if the m ower is
properly maintained and operated correctly.
1.5.8. Check all bolts frequently to maintain proper tightness.
1.5.9. Keep all guar ds, shields and all safety devices in place and in safe working
condition.
1.5.10 Frequently check for worn or deterior ating components that could create a
hazard.
1.5.11 All replacement parts must be the same as or equivalent to the parts supplied
as original equipment.
wear loose fitting clothing or j ewelry that could get tangled in
POTENTIAL HAZARD
♦ Hydraulic fluid escaping under pressure can penetrat e
skin and cause injury.
WHAT CAN HAPPEN
♦ Fluid accidentally injected into the skin must be
surgically removed within a few hours by a doctor
familiar with this form of injury or gangrene ma y result .
HOW TO AVOID THE HAZARD
♦ Make sure all hydraulic fluid hoses and lines are in
good condition an all hydraulic connections and fittings
are tight before applying pressure to hydraulic system.
♦ Keep body and hands away from pinhole leaks or
nozzles that eject high pressure hydraulic fluid.
♦ Use cardboard or paper to find hydraulic leaks.
♦ Safely relieve all pressure in the hydraulic system
before performing any work on t he hydraulic system.
