central time, with an Exmark Parts Plus order of six (6) line items or less.  
If order is received by 3:00 p.m. central time, Exmark ships part(s) direct to dealer or customer, as requested by  
distributor, same day, overnight UPS, Exmark bills the distributor for parts and shipping charges, where applicable.  
The customer pays for the part and freight if it is shipped under the Exmark Parts Plus and if it arrives in  
accordance to the program.  
Who pays for the part and freight if it fails to arrive overnight in accordance to the program?  
A. Under any circumstance the customer does not pay.

to Exmark by 3:00 p.m., central time, the Distributor pays for the part and freight.  
3. Exmark being unable to ship the part and the Exmark parts order is received by 3:00 p.m., central time,  
Exmark pays for the part and freight.

1.2.1  
1.2.2  
1.2.3  
1.2.4  
Regard the Exmark mower as a piece of power equipment and teach this  
regard to all who operate this unit.  
Read the instructions carefully. Familiarize yourself with the controls and the  
proper use of the equipment.  
Never allow children, teenagers, or people unfamiliar with these instructions to  
use the mower.  
Avoid mowing while people, especially children, or pets, are nearby. Keep in  
mind that the operator or user is responsible for accidents or hazards occurring  
to other people or their property.  
1.3 PREPARATION  
1.3.1  
1.3.2  
1.3.3  
The use of personal protective equipment, such as (but not limited to)  
protection for the eyes, ears, feet and head is recommended.  
While mowing, always wear substantial footwear and long trousers. Do not

WARNING  
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 to 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.  
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 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 starting 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 until 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 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.  
1.4 OPERATION  
Although hazard control and accident prevention partially 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, 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.  
1.4.1  
1.4.2  
Give complete, undivided attention to the job at hand.

slopes greater than 15 degrees. Watch for ditches, 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 transfer to the front wheels  
DO NOT  
may cause drive wheels to slip and cause loss of braking.  
mow  
slopes when grass is wet - slippery conditions affect steering and reduce  
traction and braking. The operator is responsible for safe operation on slopes.

add oil to gasoline.  
Never fill the fuel tank so that the fuel level rises above a level that is 1/2” below  
the bottom of the filler neck to allow for fuel expansion and prevent fuel spillage.  
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.

CAUTION  
POTENTIAL HAZARD  
This unit does not have proper turn signals, lights,  
reflective markings, or a slow moving vehicle emblem.  
These items are required to drive on a public street or  
roadway.  
WHAT CAN HAPPEN  
Driving on a street or roadway without such equipment  
is dangerous and can lead to accidents causing  
personal injury.  
Driving on a street or roadway without such equipment  
may also be a violation of State laws and the operator  
may be subject to traffic tickets and/or fines.  
HOW TO AVOID THE HAZARD  
Do not drive a unit on a public street or roadway.  
WARNING  
POTENTIAL HAZARD  
Loading a unit on a trailer or truck increases the  
possibility of backward tip-over.  
WHAT CAN HAPPEN  
Backward tip-over of the unit could cause serious  
injury or death.  
HOW TO AVOID THE HAZARD  
Use extreme caution when operating a unit on a ramp.  
Use only a single, full width ramp; DO NOT use  
individual ramps for each side of the unit.  
If individual ramps must be used, use enough ramps to  
create an unbroken ramp surface wider than the unit.  
DO NOT exceed a 15° angle between ramp and  
ground or between ramp and trailer or truck.  
Avoid sudden acceleration while driving unit up a ramp  
to avoid tipping backward.  
Avoid sudden deceleration while backing unit down a  
ramp to avoid tipping backward.  
4.4.2  
Loading a Unit: Use extreme caution when loading units on trailers or trucks.  
One full width ramp that is wide enough to extend beyond the rear tires is  
recommended instead of individual ramps for each side of the unit. The lower  
rear section of the tractor frame extends back between the rear wheels and  
serves as a stop for tipping backward. Having a full width ramp provides a  
surface for the frame members to contact if the unit starts to tip backward. If it  
is not possible to use one full width ramp, use enough individual ramps to  
simulate a full width continuous ramp.  
- 18 -  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Ramp should be long enough so that the angles between the ramp and the  
ground and the ramp and the trailer or truck do not exceed 15°. A steeper  
angle may cause mower deck components to get caught as the unit moves  
from ramp to trailer or truck. Steeper angles may also cause the unit to tip  
backward. If loading on or near a slope, position the trailer or truck so it is on  
the down side of the slope and the ramp extends up the slope. This will  
minimize the ramp angle. The trailer or truck should be as level as possible.  
DO NOT attempt to turn the unit while on the ramp, you may lose control and  
drive off the side.  
Avoid sudden acceleration when driving up a ramp and sudden deceleration  
when backing down a ramp. Both maneuvers can cause the unit to tip  
backward.

6. WASTE DISPOSAL  
6.1 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.  
6.2 MERCURY SWITCH DISPOSAL  
CAUTION  
POTENTIAL HAZARD  
The mercury contained in the tilt switch is poisonous.  
WHAT CAN HAPPEN  
Exposure to mercury can cause severe illness.  
HOW TO AVOID THE HAZARD  
Never attempt to open or repair the tilt switch  
Avoid contact with the mercury.  
The tilt switch (PN 633782) on this unit contains mercury, a hazardous material.  
Mercury that is outside a sealed container vaporizes at room temperature. The vapors  
are harmful. Mercury can be absorbed through the skin. Do not attempt to open or  
repair this switch.  
A very small amount of mercury is contained in a hermetically sealed body. The steel  
switch is then potted in a hard epoxy in a plastic case. It is unlikely that the mercury will  
ever escape from the enclosure. These high performance and reliable inexpensive  
switches are recyclable. Mercury is an important and beneficial compound but requires  
special care in handling and disposal. When used and managed properly, mercury is  
not a threat to people or the environment. This information is presented to users so that  
they are aware that these switches contain mercury and will apply sound disposal  
practices when these devices reach their normal end of life or are damaged.  
Several states have passed laws concerning the disposal of devices containing mercury.  
In all the remaining states it is advisable to follow similar procedures. The laws state  
that these sealed devices contain mercury and should not be placed in the garbage until  
the mercury is removed and reused, recycled or otherwise managed to insure that it  
does not become part of solid waste or waters. Management and disposal practices  
must be within relevant federal, state or local laws.  
Return the switch to your Exmark dealer if it is faulty and is being replaced or if the unit  
containing the switch is no longer operating and is being scrapped. If the switch is  
damaged or broken open use extreme caution in handling. Call you local waste  
management authority or Exmark Customer Service for instructions.

6.3 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.  
7. TROUBLE SHOOTING  
7.1 MOWER PULLS LEFT OR RIGHT (W/LEVERS FULLY FORWARD).  
a) It is common for a machine to pull slightly left or right with levers fully  
forward. Move levers forward and compensate as neccessary  
b) Check air pressure in tires; 13 psi/drive, 13 psi/ pneumatic castors.  
c) Check reverse indicator and motion control linkage adjustment. See  
Section 5.2.10 and 5.2.11.  
7.2 MOWER CUTS UNEVENLY.  
a) Check air pressure in tires; 13 psi/drive, 13 psi/ pneumatic casters. A  
more uniform cutting height may be obtained with higher tire pressure on  
rough terrain. A lower tire pressure provides more flotation. Higher  
pressures in front casters may cause them to shimmy on hard surfaces.  
b) Check deck support chains.  
c) Check deck leveling (See Adjustments Section 5.2.2.)  
Note: The front of the mower deck will be approximately 1/4”lower than  
the back of the mower deck.  
d) Check blades tip to tip for straightness (they should be within 3/16" or  
one blade width from being in line.)  
7.3 ENGINE WILL NOT START.  
a) Be sure the throttle control is midway between the “SLOW” and “FAST”  
positions, and the choke is in the “ON” position for a cold engine or the  
“OFF” position for a warm engine.  
b) Make sure there is fuel in the fuel tank and that the fuel valve is open.  
c) Operator must be in the seat. Be sure the seat switch is properly  
adjusted. See Section 5.2.5.  
d) Make sure the parking brake is set and motion control levers are moved  
out (neutral lock position).  
- 33 -  
Download from Www.Somanuals.com. All Manuals Search And Download.  
e) Check that the blades are disengaged.  
f) Check that the spark plug wires are properly connected.  
g) Check for loose or faulty wiring connections.  
h) Check for corrosion at all wiring connections. Even minor corrosion may  
cause a faulty connection. Clean connector terminals thoroughly with  
electrical contact cleaner, apply dielectric grease and reconnect.  
NOTE: When disconnecting electrical connectors DO NOT pull on the  
wires to separate the connectors.  
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 condition prior to mower use.  
When a problem occurs, do not overlook the simple causes. For example,  
starting problems could be caused by an empty fuel tank. The following table  
lists some of the common causes of trouble. Do not attempt to service or  
replace major items or any items that call for special timing of adjustments  
procedures (such as valves, governor, etc.). Have this work done by  
your Engine Service Dealer.
