1.3.4  
1.3.5  
Thoroughly inspect the area where the equipment is to be used and remove all  
stones, sticks, wires, bones, and other foreign objects, which may damage the  
equipment or cause personal injury to the operator or bystanders.  
Always set the park brake before starting the engine.  
WARNING  
POTENTIAL HAZARD  
Engine exhaust contains carbon monoxide, which is  
an odorless deadly poison.  
WHAT CAN HAPPEN  
Carbon monoxide can kill you.  
HOW TO AVOID THE HAZARD  
Do not run engine indoors or in a small confined area  
where dangerous carbon monoxide fumes can collect.  
DANGER  
POTENTIAL HAZARD  
In certain conditions gasoline is extremely flammable  
and highly explosive.  
WHAT CAN HAPPEN  
A fire or explosion from gasoline can burn you, others,  
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 may be ignited  
by spark.  
Refuel only outdoors.  
Store gasoline in an approved container and keep it  
out of the reach of children.

DANGER  
POTENTIAL HAZARD  
In certain conditions gasoline is extremely flammable  
and highly explosive.  
WHAT CAN HAPPEN  
A static charge can ignite gasoline 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 filling.  
Do not fill gasoline containers inside a vehicle or on a  
truck or trailer bed because interior carpets or plastic  
truck bed liners may insulate the container and slow  
the loss of any static charge.  
When practical, remove 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 than  
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.  
WARNING  
POTENTIAL HAZARD  
Gasoline vapor can collect inside enclosed trailers and  
may be ignited by electrical sparks or hot  
engine/exhaust components.  
WHAT CAN HAPPEN  
Explosion and fire may occur, resulting in property  
damage, personal injury, and/or death.  
HOW TO AVOID THE HAZARD  
Provide adequate ventilation of any enclosed trailer to  
prevent build up of gasoline vapors, especially at floor  
level.  
Refuel only outdoors, never inside an enclosed trailer.  
Be sure all fuel tanks and gasoline storage containers  
have proper caps installed to prevent spillage and  
minimize vapor escaping into the trailer.  
Do not place any equipment that is leaking gasoline in  
an enclosed trailer.

1.4 OPERATION  
Although hazard control and accident prevention are partially 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, maintenance, and storage of the equipment.  
It is essential that all Operator Safety Mechanisms be connected and in operating  
condition prior to use for mowing.  
WARNING  
POTENTIAL HAZARD  
Operating engine parts, especially the muffler, become  
extremely hot.  
WHAT CAN HAPPEN  
Severe burns can occur on contact.  
Debris, such as leaves, grass, brush, etc. can catch fire.  
HOW TO AVOID THE HAZARD  
Allow engine parts, especially the muffler, to cool before  
touching.  
Remove accumulated debris from muffler and engine area.  
Install and maintain in working order a spark arrester before  
using equipment on forest-covered, grass-covered, or  
brush-covered unimproved land.  
WARNING  
POTENTIAL HAZARD  
Hands, feet, hair, clothing, or accessories can become  
entangled in rotating parts.

DANGER  
POTENTIAL HAZARD  
Mowing on wet grass or steep slopes can cause sliding and  
loss of control.  
WHAT CAN HAPPEN  
Wheels dropping over edges, ditches, steep banks, or  
water can cause rollovers, which may result in serious  
injury, death or drowning.  
HOW TO AVOID THE HAZARD  
Mow up and down slopes.  
Do not mow slopes when grass is wet.  
Do not mow near drop-offs or near water.  
Do not mow slopes greater than 15 degrees.  
Reduce speed and use extreme caution on slopes.  
Avoid sudden turns or rapid speed changes.  
See inside the back cover to determine the approximate slope angle of the  
area to be mowed.  
Use a walk behind mower and\or a hand trimmer near drop-offs, ditches,  
steep banks or water. This area can be dangerous, see Figure 1.  
G0083  
Figure 1  
SAFE ZONE FOR MOWING  
Progressively greater care is needed as the slope increases.  
Always avoid sudden starts and turns.  
Be aware that loss of traction may occur going downhill. Weight transfer to  
the front wheels may cause rear wheel to lift off ground cause loss of  
steering.  
Watch for ditches, holes, rocks, dips, and rises that change the operating  
angle, as rough terrain could overturn the machine.  
Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing  
area. Tall grass can hide obstacles.  
Use extreme care with grass catchers or attachments. These can change  
the stability of the machine and cause loss of control.  
1.4.5  
1.4.6  
Use EXTREME caution when backing up. LOOK BEHIND YOU!  
Stop the blades when crossing surfaces other than grass and when  
transporting the mower to and from the area to be mowed.

position. Rotate clockwise to the next position to engage the starter (key must be held  
against spring pressure in this position). Operator must be in seat with brake engaged  
and PTO disengaged to start engine. When engine starts, release key. DO NOT leave  
key in the “ON” position without engine running, this will run down the battery.  
4.9 Hour Meter: Located on the steering console just below the steering wheel. The hour  
meter is connected to a pressure switch installed in the engine block and it records the  
number of hours that the engine has run. If ignition switch is left on without engine  
running, hour meter will not run.  
NOTE: This switch is not a low oil sensor and will not alert the operator if the engine oil  
is low.  
4.10 Fuel Shut-Off Valve: Located in the fuel line near the right rear corner of the engine.  
The fuel shut-off valve is used to shut off the flow of fuel when parking inside a  
building, during transportation to and from job sites and when the machine will not be  
used for a few days. Rotate valve 1/4 turn clockwise to shut fuel off. Rotate valve 1/4  
turn counter-clockwise to turn fuel on.  
4.11 Drive Wheel Release Lever: Located under the lower left rear corner of the engine deck  
(See Figure 4). The drive wheel release lever is used to release the hydrostatic drive  
system to allow machine to be pushed while the engine is not running. Rotate lever 1/8  
turn counter-clockwise until caught under spring latch to release drive system. Pull  
spring latch out far enough to allow lever to rotate 1/8 turn clockwise to engage drive

6.2.13 Steering Chain Adjustment  
a) Stop engine, wait for all moving parts to stop, and remove key.  
b) Position the steering handle bar so that it points the unit straight forward (the  
rear steering wheel should be in line with the rider main frame channel).  
c) Check to see if the chains are loose.  
d) To take up slack in the chains, loosen the rear jam nuts connecting the  
eyebolts to cross link bars, then equally tighten each forward jam nut until  
slack is taken up. Retighten the forward jam nuts onto the links.  
e) If the unit tends to turn left when handle bar is positioned for straight forward  
travel, adjust by shortening the right hand link (threading jam nuts closer to  
“eye” end of the eyebolt) and lengthening the left hand link (threading jam  
nuts away from the “eye” end of the eyebolt) an equal amount. Re check  
chain tension.  
f) If the unit tends to turn right when handle bar is positioned for straight  
forward travel, reverse procedure as stated in paragraph “d” above.  
6.2.14 Throttle Control Adjustment  
a) Stop engine, wait for all moving parts to stop, and remove key.  
b) Loosen the cable clamp on the engine and position the throttle control at the  
control console within 1/4” (6mm) from the upper end of the slot. Pull on  
cable assembly at lower end, where it attached to the engine, until the  
throttle control arm contacts the stop screw. Secure cable with cable clamp.  
6.2.15 Throttle Cable Tension  
a) Stop engine, wait for all moving parts to stop, and remove key.  
b) Tension in throttle lever can be adjusted by adjusting the tightness of the  
lever pivot bolt, which is located under the console. See Figure 17.

7. WASTE DISPOSAL  
7.1 MOTOR OIL DISPOSAL.  
Engine oil and hydraulic oil are both pollutants to the environment. Dispose of used oil  
at a certified recycling center or according to your state and local regulations.  
7.2 BATTERY DISPOSAL  
DANGER  
POTENTIAL HAZARD  
Battery electrolyte contains sulfuric acid, which is  
poisonous and can cause severe burns  
WHAT CAN HAPPEN  
Swallowing electrolyte can be fatal or if it touches skin  
can cause severe burns.  
HOW TO AVOID THE HAZARD  
Wear safety glasses to shield eyes, and rubber gloves  
to protect skin and clothing when handling electrolyte.  
Do not swallow electrolyte.  
Federal law states that batteries should not be placed in the garbage. Management and  
disposal practices must be within relevant federal, state, or local laws.  
If a battery is being replaced or if the unit containing the battery is no longer operating  
and is being scrapped, take the battery to a local certified recycling center. If no local  
recycling is available return the battery to any certified battery reseller.  
8. TROUBLE SHOOTING  
8.1 MOWER CUTS UNEVENLY.  
a) Check air pressure in tires. See Section 2.8. A more uniform cutting height may be  
obtained with higher tire pressure on rough terrain. A lower tire pressure provides  
more flotation.  
b) Check deck support pins. Hairpin clips must be in the same hole on each support pin.  
c) Check blades tip to tip for straightness. Blades should be within 3/16” or one blade  
width from being in line.  
8.2 ENGINE WILL NOT START.  
a) Make sure battery has a full charge.  
b) Check that throttle control is midway between “slow” and “fast” positions, and choke  
is in “on” position for a cold engine or “off” position for a warm engine.  
c) Be sure there is fuel in the tank and that the fuel valve is open.  
d) Operator must be in the seat.  
e) Check that parking brake is set.  
f) Be sure that the PTO is disengaged.  
g) Check that the spark plug wires are properly connected.  
h) Look for loose or faulty wiring connections.  
i) Check for corrosion at all wiring connections. Even minor corrosion may cause a  
faulty connection. Clean connector terminals thoroughly and reconnect.  
NOTE: When disconnecting electrical connectors, DO NOT pull on the wires to  
separate connectors.  
j) Check that the seat switch is properly adjusted. See Section 6.2.12.  
k) Check that the parking brake switch is properly adjusted. See Section 6.2.10.

NOTE: After carefully checking the above steps, attempt to start the engine. If it  
does not start, contact your authorized Exmark service dealer.  
IMPORTANT: It is essential that all Operator Safety Mechanisms be connected and  
in proper operating conditions prior to the use of the mower.  
ENGINE TROUBLESHOOTING  
When a problem occurs, do not overlook the simple causes. For example, starting  
problems could be caused by an empty fuel tank.  
The following tables list some common causes of troubles. Do not attempt to service or  
replace major items or any items that call for special timing or adjustment procedures  
(governor, valves, etc.). Have this work done by your Engine Service Dealer.
