Operating Safety
Congratulations on purchasing a superior-quality piece of
lawn and garden equipment. Our products are designed and
manufactured to meet or exceed all industry standards for
safety.
Do not operate this machine unless you have been trained.
Reading and understanding this operator’s manual is a way to
train yourself.
Children
Tragic accidents can occur with children. Do not allow them
anywhere near the area of operation. Children are often
attracted to the unit and mowing activity. Never assume that
children will remain where you last saw them. If there is a risk
that children may enter the area where you are mowing, have
another responsible adult watch them.
Power equipment is only as safe as the operator. If it is
misused, or not properly maintained, it can be dangerous!
Remember, you are responsible for your safety and that of
those around you.
Use common sense, and think through what you are doing.
If you are not sure that the task you are about to perform can
be safely done with the equipment you have chosen, ask a
professional: contact your local authorized dealer.
Read the Manual
The operator’s manual contains important safety information
you need to be aware of BEFORE you operate your unit as
well as DURING operation.
Safe operating techniques, an explanation of the product’s
features and controls, and maintenance information is
included to help you get the most out of your equipment
investment.
Slope Operation
Operation on slopes can be dangerous. Using the unit on
a slope that is too steep where you do not have adequate
wheel traction (and control) can cause sliding, loss of
steering, control, and possible rollover. You should not
operate on a slope greater than 15 degrees (a 5.4 foot rise
over a 20 foot length).
Avoid turning down slopes; if possible turn up slopes. Avoid
sudden turns or rapid speed changes. Reduce speed and use
extreme caution on ALL slopes.
Also, note that the surface condition you are on can greatly
impact your ability to safely operate this machine. Operating
on wet or slippery slopes can cause sliding and loss of
steering and control. Do not operate on slopes that are
slippery, wet, or have soft soil conditions.
Be sure to completely read the Safety Rules and Information
found on the following pages. Also completely read the
Operation section.
If you feel unsure about operating the unit on a slope, don’t
do it. It’s not worth the risk.

Thrown Objects
This unit has spinning mower blades. These blades can pick
up and throw debris that could seriously injure a bystander.
Be sure to clean up the area to be mowed and remove
objects that could be thrown by the blade BEFORE you start
mowing.
Do not operate this unit without the entire grass catcher or
discharge guard (deflector) in place.
Also, do not allow anyone in the area while the unit is running!
If someone does enter the area, shut the unit off immediately
until they leave.
Keep the roll bar in the raised position and fasten the seat
belt. There is no roll over protection when the roll bar is down!
Do not jump off if the mower tips (it is safer to be secured by
the seat belt with the roll bar raised.)
Lower the roll bar only when necessary (such as to
temporarily clear a low overhanging obstacle) and NEVER
remove it. Do NOT use the seat belt when the roll bar is
down. Raise the roll bar as soon as clearance permits.
Retaining Walls, Drop-Offs and Water
Moving Parts
This equipment has many moving parts that can injure you
or someone else. However, if you stay in the operator zone
(stay seated in the seat), and follow the safety rules in this
operator’s manual, the unit is safe to operate.
The mower deck has spinning mower blades that can
amputate hands and feet. Do not allow anyone near the unit
while it is running! Keep safety devices (guards, shields, and
switches) in place and working.
To help you, the operator, use this equipment safely, it is
equipped with an operator-present safety system. Do NOT
attempt to alter or bypass the system. See your dealer
immediately if the system does not pass all the safety
interlock system tests found in this manual.
Retaining walls and drop-offs around steps and water are
a common hazard. Do NOT operate down slope towards or
near water, retaining walls, or drop-offs.
Give yourself a minimum of two mower widths of clearance
around these hazards and hand-trim with a walk behind
mower or string trimmer. Wheels dropping over retaining
walls, edges, ditches, embankments, or into water can
cause rollovers, which may result in serious injury, death, or
drowning.
Overhead Obstacles
Check for overhead clearances before driving under any
objects. Do not allow the roll bar to contact low overhanging
obstacles such as tree branches and guide wires.
Roll Bar Use
Fuel and Maintenance

protective structure can cause serious injury or death.
A ROLL BAR, like any other safety device, needs to be
periodically inspected to verify that the integrity of the device
has not been compromised through normal machine use,
misuse, age degradation, modifications, or a roll over.
To maintain operator roll over protection and roll bar
effectiveness:
• If a ROLL BAR becomes damaged for any reason, such
as a collision, roll over or impact, the ROLL BAR must
be replaced. Small undetectable cracks can reduce the
effectiveness of the ROLL BAR. Never weld, straighten,
or repair the ROLL BAR.
• Never alter the ROLL BAR by welding anything to it or by
drilling additional holes.
• BEFORE FIRST TIME USE - Inspect the ROLL BAR
structure and mounting hardware for:
1) Check to make sure the machine GVW (Gross Vehicle
Weight), including attachments, restrained payload, fuel
and operator, is not in excess of the maximum weight
specified on the ROLL BAR label.
2) Make sure there isn’t any missing, damaged, or loose
mounting hardware.
3) Make sure the ROLL BAR has been correctly and
completely installed.
• EVERY 100 HOURS - Inspect the ROLL BAR structure
and mounting hardware for:
1) Any cracks in the structure (structural members and/or
welds).
2) Significant corrosion on any part of the ROLL BAR
structure or hardware.
3) Missing, damaged, or loose mounting hardware
4) Mounting hardware that is of a grade lesser than
specified.
5) Machine GVW (Gross Vehicle Weight), including
attachments, restrained payload, fuel and operator, in
excess of the maximum weight specified on the ROLL
BAR label.
6) Any modifications that have been made, such as
unauthorized welds and holes.
7) Any permanent deformation or twisting of the ROLL
BAR structure.
8) That the ROLL BAR label is still in place and is
readable.
Inspection and Maintenance of the Roll Bar
Seat Belt
WARNING
Failure to properly inspect and maintain the seat belt can
cause serious injury or death.

immediately, and consult engine operator's manual.
Warm up the engine by running it for at least a minute
before engaging the PTO switch or driving the rider.
4. After warming the engine always operate the unit at FULL
throttle when mowing.
In the event of an emergency the engine can be stopped
by simply turning the ignition switch to STOP. Use this
method only in emergency situations. For normal engine shut
down follow the procedure given in Stopping the Rider.
Stopping the Rider
1. Returning the ground speed control levers to the middle
position will stop rider movement. Pivot the levers
outward and lock them in NEUTRAL.
2. Disengage the PTO by pushing down on the PTO switch.
3. Engage the parking brake by pulling the handle up until it
locks into position.
4. Move the throttle control to mid-throttle position and turn
the ignition key to OFF. Remove the key.
Zero-Turn Driving Practice
The lever controls of the Zero Turn rider are responsive, and
learning to gain a smooth and efficient control of the rider’s
forward, reverse, and turning movements will take some
practice.
Spending some time going through the maneuvers shown
and becoming familiar with how the unit accelerates, travels,
and steers — before you begin mowing —is absolutely
essential to getting the most out of the Zero Turn rider.
Locate a smooth, flat area of your lawn— one with plenty
of room to maneuver. (Clear the area of objects, people and
animals before you begin.) Operate the unit at mid-throttle
during this practice session (ALWAYS operate at full throttle
when mowing), and turn slowly to prevent tire slippage and
damage to your lawn.
We suggest you begin with the Smooth Travel procedure to
the right, and then advance through the forward, reverse, and
turning maneuvers.
You must release the parking brake prior to moving the
control levers inward.
Smooth Travel
The lever controls of the Zero Turn rider are responsive.
The BEST method of handling the ground speed control
levers is in three steps — as shown in Figure 11.
1. While sitting in the operator's seat, engage the parking
brake and make sure the PTO switch is disengaged and
the ground speed control levers are locked in the neutral
position.
2. Position the throttle control midway between SLOW and
FAST positions.
3. Insert the key into the ignition switch and turn it to START
position. Release switch as soon as engine starts. If
starter does not turn engine over, shut off key switch

While traveling forward allow one handle to gradually return
back toward neutral. Repeat several times.
NOTE: To prevent pivoting directly on the tire tread, it is best
to keep both wheels going at least slightly forward.

To turn in place, “Zero Turn,” gradually move one ground
speed control lever forward from neutral and one lever back
from neutral simultaneously. Repeat several times.
NOTE: Changing the amount each lever is pulled—forward or
back, changes the “pivot point” you turn on.
Advanced Driving
Executing an End-Of-Row Zero Turn
As you become more familiar and experienced with operating
the Zero Turn rider, you will learn more maneuvers that will
make your mowing time easier and more enjoyable.
Remember, the more you practice, the better your control
of the Zero Turn will be!
Mowing
1. Engage the parking brake. Make sure that the PTO
switch is disengaged, the ground speed control levers are
locked in the NEUTRAL position and the operator is in the
seat.
2. Start the engine. See Starting the Engine.
3. Set the mower cutting height.
4. Set the throttle to the 1/2 throttle position.
Note: It is best practice to engage the PTO with the throttle
set at the minimum throttle position necessary to engage the
deck drive system without stalling the engine.
5. Engage the PTO by pulling up on the PTO switch.
6. Move the throttle to the "FAST" position and begin
mowing.
7. When finished, reduce throttle speed so that the engine
idles and push the PTO switch down to shut off the PTO.
8. Stop the engine. See Stopping the Rider.
16
Your Zero Turn Rider’s unique ability to turn in place allows
you to turn around at the end of a cutting row rather than
having to stop and Y-turn before starting a new row.
For example, to execute a left end-of row zero turn:
1. Slow down at the end of the row.
2. Move the RIGHT ground speed control lever forward
slightly while moving the LEFT ground speed control lever
back to center and then slightly back from center.
3. Begin mowing forward again.
This technique turns the rider LEFT and slightly overlaps
the row just cut —eliminating the need to back up and re-cut
missed grass.
Mowing Recommendations
Several factors can affect how well your machine cuts grass,
Following proper mowing recommendations can improve the
performance and life of your machine.
Height of Grass
Often cutting height is a matter of personal preference.
Typically, you should mow the grass when it is between three
and five inches high. The proper cutting height range for
a specific lawn will depend upon several factors, including
the type of grass, the amount of rainfall, the prevailing
temperature, and the lawn’s overall condition.
Cutting the grass too short causes weak, thin grass plants,
which are easily damaged by dry periods and pests. Cutting
too short is often more damaging than allowing the grass to
be slightly higher.
Letting grass grow a bit longer—especially when it is hot and
dry—reduces heat build-up, preserves needed moisture and
protects the grass from heat damage and other problems.
However, allowing grass to grow too high can cause thin turf
and additional problems.
Cutting off too much at one time shocks the plant’s growth
system and weakens the grass plants.A good rule of thumb
is the 1/3 rule: to cut no more than one third of the grass
height, and never more than 1 inch at a time.
19
Page 20

17
The amount of grass you are able to cut in one pass is also
effected by the type of mowing system you are using (for
example, broadcasting with side discharge decks can process
a much larger volume of grass than mulching does).
Tall grass requires incremental cutting.For extremely tall
grass, set the cutting height at maximum for the first pass (A,
Figure18), and then reset it to the desired height and mow a
second (B) or third time.
• Avoid mowing after rain or even heavy dew, and never
mulch when the grass is wet (moist grass does not mulch
well, and clumps beneath the mower deck).
Mowing Patterns
Always start mowing on a smooth, level area.
The size and type of area to be mowed will determine the
best mowing pattern to use. Obstructions such as trees,
fences and buildings, and conditions such as slopes and
grades must also be considered.
• Cut long straight strips overlapping slightly.
• Where possible, change patterns occasionally to
eliminate matting, graining or a corrugated appearance.
• For a truly professional cut, mow across the lawn in one
direction, then re-cut the lawn by mowing perpendicular to
the previous cut.
Note: Always operate the engine at FULL THROTTLE when
mowing.
If you hear the engine slowing down, you are mowing too
fast—using a slower ground speed will improve the cutting
efficiency of the blades and prevents many common cutting
problems. Use an appropriate ground speed for the thickness
and height of the grass you are cutting (3rd gear or slower for
manual gear models). If you hear the engine slowing down
you are mowing too fast, use a slower ground speed.
Don’t cover the grass surface with a heavy layer of clippings.
Consider using a grass collection system and starting a
compost pile.
18
When and How Often to Mow
The time of day and condition of the grass greatly affect the
results you’ll get when mowing. For the best results, follow
these guidelines:
• Mow when the grass is between three and five inches
high.
• Mow with sharp blades. Short clippings of grass one inch
or shorter decompose more quickly than longer blades.
Sharp mower blades cut grass cleanly and efficiently,
preventing frayed edges which harm the grass.
• Mow at time of day when the grass is cool and dry. Late
afternoon or early evening often provide these ideal
mowing conditions.
19
Where possible, make one or two passes around the outside
of the area discharging the grass INTO the lawn to keep the
cut grass off fences and walks.
20
20 simplicitymfg.com
Page 21
Not for
Reproduction
The remainder of the mowing should be done in the opposite
direction so that the clippings are dispersed OUT onto the
area of lawn previously cut.
Mowing Methods
Broadcast Mowing
Broadcasting, or side-discharging, disperses fine clippings
evenly over the entire lawn. Many golf courses use this
method. Your mower has a deep dish deck to allow freer
circulation of clippings so they are broadcast evenly over the
lawn.
Engine Speed & Ground Speed for Broadcasting:
Always operate the engine at full throttle when mowing.
If you hear the engine slowing down, you are mowing too
fast—using a slower ground speed will improve the cutting
efficiency of the blades and prevents many common cutting
problems.
ALWAYS use an appropriate ground speed for the thickness
and height of the grass you are cutting (3rd gear or slower for
manual gear models). If you hear the engine slowing down
you are mowing too fast, use a slower ground speed.
How Much Grass to Cut Off When Broadcasting:
Mow when the grass is 3-5 inches long. Do not cut the grass
shorter than 2 to 2-1/2 inches. Do not cut off more that 1 inch
of grass in a single pass.
Mulching
Mulching consists of a mower deck which cuts and re-cuts
clippings into tiny particles and which then blows them down
INTO the lawn. These tiny particles decompose rapidly
into by-products your lawn can use. UNDER PROPER
CONDITIONS, your mulching mower will virtually eliminate
noticeable clippings on the lawn surface.
The best mulching action typically results from cutting only
the top ½ inch to 3/4 inch of grass blade. This provides
short clippings which decompose properly (much more
quickly than longer clippings). The ideal cutting height will
vary with climate, time of year, and quality of your lawn. We
recommend that you experiment with both the cutting height
and ground speed until you achieve the best cut. Start with
a high cutting height and using progressively lower settings
until you find a cutting height that is matched to your mowing
conditions and preferences.
Pushing the Rider By Hand
NOTICE
Do NOT tow zero-turn rider.
Towing the units will cause hydraulic transmission damage.
Do not use another vehicle to push or pull this unit.
1. Disengage the PTO, engage the parking brake, turn the
ignition OFF, and remove the key.
2. Locate the transmission release lever on top of the
transmission of the unit. There is one transmission
release lever on each transmission. The transmission
release levers open and close the transmission bypass
valves.
3. To open the transmission bypass valves rotate the
transmission release levers to the "bypass" position (A,
Figure 21). The transmission release levers will contact
the bodies of the transmissions. The transmission release
levers will be oriented so that they are perpendicular to
the axles of the transmissions.
Note: When mulching under heavy cutting conditions, a
rumbling sound may be present and is normal.
Mulching Requires EXCELLENT Mowing Conditions:
Mulching mowers cannot function properly if the grass is wet,
or if the grass is simply to high to cut. Even more than normal
mowing, mulching requires that the grass be dry and the
appropriate amount is cut.
Do not use the mower as a mulching mower during the
first two or three mowings in the spring. The long grass
blades, quick growth, and often wetter conditions are more
suitable for broadcasting (side-discharging) or grass bagging
operation.
Engine Speed & Ground Speed for Mulching:
Use full engine throttle matched with a slow ground speed so
that clippings will be finely cut. Ground speed while mulching
should be HALF of the speed that would be used when
broadcasting (side discharging) under similar conditions.
Since mulching requires more horsepower than broadcasting,
using a slower ground speed is vitally important for proper
mulching operation.

the bodies of the transmissions. The transmission release
levers will be oriented so that they are parallel to the
axles of the transmissions.
Note: Both transmission release levers must be in the same
position.
Raise and Lower the Roll Bar
WARNING
Avoid serious injury or death from roll over:
• Keep roll bar in the raised position and use seat belt.
• There is no roll over protection when the roll bar is
down.
• Lower the roll bar only when necessary and NEVER
remove it.
• Do NOT use seat belt when the roll bar is down.
• Raise the roll bar as soon as clearance permits.
• Do NOT jump off if mower tips.
2. Push or pull the top of the roll bar (C) forward against the
spring clips (D) and remove the retainer pins (B).
3. Lower the roll bar and reinstall the retainer pins and hair
pin clips to secure the roll bar in the down position (see

Excessive towed loads can cause loss of traction and loss of
control on slopes. Reduce towed weight when operating on
slopes. The surface being driven on greatly impacts traction
and stability. Wet or slippery surfaces can greatly reduce
traction and the ability to stop or turn. Carefully evaluate
the surface conditions before operating the unit and trailer,
and never operate on slopes greater than 10°. See SLOPE
OPERATION and TOWED EQUIPMENT in the safety section
of this manual for additional safety information.
Storage
WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or death.
• Never store the unit, with gasoline in the engine or
the fuel tank, in a heated shelter or in an enclosed,
poorly ventilated enclosures. Gasoline fumes may
reach an open flame, spark or pilot light (such as a
furnace, water heater, clothes dryer, etc.) and cause
and explosion.
• Handle gasoline carefully. It is highly flammable and
careless use could result in serious fire damage to your
person or property.
• Drain fuel into an approved container outdoors away
from open flame or sparks.
Temporary Storage (30 Days or Less):
Remember, the fuel tank will still contain some gasoline, so
never store the unit indoors or in any other area where fuel
vapor could travel to any ignition source. Fuel vapor is also
toxic if inhaled, so never store the unit in any structure used
for human or animal habitation.
Here is a checklist of things to do when storing your unit
temporarily or in between uses:
• Keep the unit in an area away from where children

8. Perform the Purging the Air from the Hydraulic System
procedure.
Purging the Air from the Hydraulic
System
Due to the effects air has on efficiency in hydraulic drive
systems, it is critical that it be purged from the system.
These purge procedures should be implemented any time a
hydraulic system has been opened to facilitate maintenance
or any additional oil has been added to the system.
The resulting symptoms of air in the hydraulic system may be:
• Noisy operation.
• Lack of power or drive after short term operation.
• High operation temperature and excessive expansion of
oil.
Before starting, make sure the transaxles/transmissions are
at the proper oil levels. If it is not, fill to the specifications
outlined in the Check / Fill Transmission Oil Level procedure.
Purging Air from the Hydraulic System:
1. Chock the front wheels to prevent the machine from
28 simplicitymfg.com
rolling. Raise the rear of the machine so that the vehicle’s
rear tires do not contact the ground. Position jack stands
under the rear bumper of the machine to secure it.

2. Open the transaxle’s bypass valves (see Pushing the
Rider by Hand for the location and function of the bypass
valves), start the engine, release the parking brake, and
slowly move the zero-turn rider’s ground speed control
levers in both forward and reverse directions (5 to 6
times), as air is purged from the unit, the oil level will
drop.
3. Stop the engine and engage the parking brake.
4. Close the transaxle’s bypass valves, start the engine,
release the parking brake, and slowly move the zero-turn
rider’s ground speed control levers in both forward and
reverse directions (5 to 6 times), as air is purged from the
unit, the oil level will drop.
5. Stop the engine. Remove the jack stands from
underneath the machine.
6. Repeat the process detailed above but with the unit's
drive wheels on the ground. The procedure should be
performed in an area free of any objects or bystanders.
It may be necessary to repeat the process detailed above
until all the air is completely purged from the system. When
the transaxles/transmissions operate at normal noise levels
and move smoothly forward and reverse at normal speeds,
then the transaxles/transmissions are considered purged.

Parking Brake Adjustment
The parking brake mechanism consists of two parking brake
cables (A, Figure 52) that connect the parking brake cable
shaft to the parking brake control arms on the transmissions.
There is a parking brake spring (B) on each park brake
cable located underneath the seat plate and connected to
the parking brake shaft. The position of the of the parking
brake cables in the transmission cradle and the frame of the
unit is factory preset and should not be changed for parking
brake adjustment procedures. The adjustment is achieved by
changing the compressed spring length of the parking brake
springs.

Suspension Adjustment
The shock assemblies (A, Figure63) can be adjusted in two
ways to allow the operator to customize the ride according to
the operator's weight and/or operating conditions. You have
the option of adjusting the spring pre-load and/or the upper
mounting position.
63
• Before adjusting the upper shock mount to a higher
numbered position, you should attempt to achieve the
ride height through the spring pre-load adjustment.
• Shock mounting position #3 should always be used when
a rear mounted grass collection system is installed on the
unit.
To Adjust the Spring Pre-load:
1. Park the machine on a flat, level surface. Disengage the
PTO, stop the engine, and engage the parking brake.
2. Chock the front wheels to prevent the machine from
rolling. Raise the rear of the machine and secure with
jack stands.
3. Remove the rear drive tires.
WARNING
Spring loaded components can kick back causing injury.
Use two hands when adjusting the shock springs. This will
prevent the wrench from slipping while pressure is being
applied.
4. Using the supplied spanner wrench (p/n 5022853) (B,
Figure63), insert the tip of the wrench into the notch in
the pre-load adjuster. While holding the wrench in place
with one hand, turncounter-clockwiseto increase the
pre-load, turnclockwiseto decrease the pre-load. Make
sure both shocks are set to the same amount of pre-load.
5. Re-install the rear drive tires. Torque the lug bolts to
85-95 ft.lbs. (115-129 Nm). Remove the jack stands from
under the machine.
Items to consider before adjusting the suspension:
• Less spring pre-load should be used with light weight
operators, which will provide a softer, more cushioned
ride.
• More spring pre-load should be used with heavy weight
operator's , which will provide a stiffer, more rigid ride.
• There are three positions in which the upper shock mount
can be positioned in. If adjusting the spring pre-load
does not achieve the ride requirement, the shock should
be moved to the next numbered upper shock mounting
position to achieve the desired ride requirement.
Note: If a collection system is installed on the unit it is
recommended that the rear suspension be adjusted stiffer
due to the added weight of the collection system.
To Adjust the Upper Mounting Position (Rear
Shocks):
1. Park the machine on a flat, level surface. Disengage the
PTO, stop the engine, and engage the parking brake.
2. Chock the front wheels to prevent the machine from
rolling. Raise the rear of the machine and secure with
jack stands. The jack stands must be under the bumper
of the machine.
3. Position the jack underneath the rear cross member
of the transmission cradle and slowly raise the rear
suspension to relieve the pressure on the upper shock
mounting bolts.
4. Remove the upper shock mounting hardware and pivot
the shock to the next higher numbered position (see
Figure63). Adjust the jack to align the shock mounts to
shocks.
5. Remove the jack from under the transmission cradle.
6. Remove the jack stands from underneath the machine.

ABOUT YOUR WARRANTY
We welcome warranty repair and apologize to you for being
inconvenienced. Warranty service is available only through
Simplicity Authorized Service Dealers. Most warranty
repairs are handled routinely, but sometimes requests for
warranty service may not be appropriate. This warranty
only covers defects in materials or workmanship. It does not
cover damage caused by improper use or abuse, improper
maintenance or repair, normal wear and tear, or stale or
unapproved fuel.
Improper Use and Abuse - The proper, intended use of
this product is described in the Operator's Manual. Using the
product in a way not described in the Operator's Manual or
using the product after it has been damaged will void your
warranty. Warranty is not allowed if the serial number on the
product has been removed or the product has been altered
or modified in any way, or if the product has evidence of
abuse such as impact damage, or water/chemical corrosion
damage.
Improper Maintenance or Repair - This product must be
maintained according to the procedures and schedules
provided in the Operator's Manual, and serviced or repaired
using genuine Briggs & Stratton parts or equivalent. Damage

caused by lack of maintenance or use of non-original parts is
not covered by warranty.
Normal Wear - Like all mechanical devices, your unit
is subject to wear even when properly maintained. This
warranty does not cover repairs when normal use has
exhausted the life of a part or the equipment. Except as
noted in the warranty period, maintenance and wear items
such as filters, belts, cutting blades, and brake pads (except
engine brake pads) are not covered by warranty due to wear
characteristics alone, unless the cause is due to defects in
material or workmanship.
Stale Fuel - In order to function correctly, this product
requires fresh fuel that conforms to the criteria specified in the
Operator's Manual. Damage caused by stale fuel (carburetor
leaks, clogged fuel tubes, sticking valves, etc) is not covered
by warranty.
Other Exclusions - This warranty excludes damage due
to accident, abuse, modifications, alterations, improper
servicing, freezing or chemical deterioration. Attachments
or accessories that were not originally packaged with the
product are also excluded. There is no warranty coverage on
equipment used for primary power in place of utility power or
on equipment used in life support applications. This warranty
also excludes failures due to acts of God and other force
majeure events beyond the manufacturer's control.
