During Operation

Do not bypass the starting circuit by shorting across the

terminals of the starter motor to start the engine. This may

cause the power unit to move suddenly.
Periodically check the starting circuit to make sure all system

components operate correctly.
If the starting system does not work, consult your Ariens

Dealer immediately.
Operate the mower only in daylight or when the area to be

mowed is lit well by artificial light.

Never remove the discharge shield from the mower because
the discharge shield directs material down toward the turf. If
the shield is damaged, be sure to replace it immediately.

Never try to clear the discharge area or the mower blades

unless you have moved the steering control levers to the

park position, put the PTO switch in the "Off" position,

switched the ignition key to the "Off" position, removed the

ignition key and disconnected the negative battery cable.

Do not operate the power unit in a confined or non-ventilated

area. Carbon monoxide gas is colorless, odorless, and can

be fatal.

Do not turn sharply when driving at high speeds.

Park the mower on a firm level surface with the steering

control levers in the park position.
When backing, be sure to turn around and look to the rear.

Do not mow in reverse unless it is absolutely necessary.
When working in groups, use caution and watch out for

others.
Always be aware of mower discharge direction. Make sure it

does not point at anyone.

Be sure the engine and rotating blades have stopped before

putting hands or feet near the blade.

Disengage the blade drive when transporting the machine
across drives, sidewalks, etc. Never raise the mower deck

while the blades are turning.

Do not put hands or feet under or into the mower when it is
running.

Do not touch the engine or muffler when the engine is
running or immediately after the engine has stopped. These
areas may be hot enough to cause serious burns.

Do not drive the machine on streets or highways. Watch for
traffic when crossing streets or while mowing close to roads.

Always inspect the mower for damage after striking a foreign
object. Always repair or replace damaged parts before
restarting the mower deck.

Do not operate the power unit without the mower deck
attached.

Make sure the machine and all attachments come to a
complete stop before dismounting.

Before dismounting, disengage the PTO, lower all
attachments, place the steering control levers in the park
position, turn off the engine, and remove the key.

Operating On Slopes
Avoid starting or stopping when going up or down a slope.

Keep all movements on a slope gradual and slow. Do not
make sudden changes in speed or direction.

If tires lose traction while on a slope, disengage the mower
blades and back slowly and gradually down the slope.

Do not turn on slopes unless necessary, and then turn slowly
and gradually downhill if possible.

Use extra caution when mowing on slopes. If you are unable
to back up on the slope, or if you do not feel comfortable on
it, then do not mow it. Do not operate the machine on slopes

that exceed 15°.
Mow across slopes, not up and down, to avoid machine

tip-over. Do not mow slopes or hills that are too steep for
safe operation.

Do not try to stabilize the machine by putting your foot on the
ground.

MAINTENANCE

Only qualified, trained adults should service the machine.
Before maintenance is performed, make sure the mower is

parked on a firm flat surface. Remove the key to prevent an
accidental start up.

Never attempt to disconnect any safety devices.
Frequently check for worn or deteriorating components that

could create a hazard.
Use only genuine Ariens replacement parts. Substitute parts

could cause product malfunction or possible injury to the
operator or bystanders.

If it is necessary to have the engine running while making
maintenance adjustments, keep hands, feet, and clothing
away from all moving parts.

Fuel System

Handle gasoline with care. Gasoline is extremely flammable

and its vapors can be explosive.

Use an approved fuel container.

Never add fuel to the mower while the engine is running or
while it is hot. Allow the engine to cool for several minutes

before adding fuel.

Keep matches, cigarettes, cigars, pipes, open flames, or

sparks away from the fuel tank and fuel container.
Always fill the fuel tanks outside using caution. Fill the tank

until the fuel is about one inch from the top of the tank. Use a
funnel or spout to prevent spilling. When refueling at a gas

pump, always ensure the nozzle contacts the neck of the
tank while filling.

Replace the machine and container caps and clean up any

spilled fuel before starting the engine.

Keep the mower and all fuel containers in a safe locked

place to keep children from tampering with them.

Fuel system components rely upon clean fuel for lubrication

and optimum performance. Extreme care must be taken to

prevent ingress of dirt and moisture to prevent damage.

Use only nonmetal portable fuel containers approved by the

Underwriter's Laboratory (U.L.) or the American Society for
Testing and Materials (ASTM). If using a funnel, make sure it

is plastic.
When practical, do not fuel the equipment on truck beds or

on trailers. Remove them and fuel on the ground. If this is

not possible, use a portable nonmetal fuel container to fill the

equipment.

Hydraulic System

Make sure all hydraulic fluid, hoses, and lines are in good

condition and all lines and fittings are tight before applying

pressure to the hydraulic system.

Check hydraulic connections frequently. They can leak as a

result of damage, as a result of vibration or because they

have worked loose.

Relieve all pressures before disconnecting hoses or lines.
Escaping oil under pressure can cause serious injury.

Escaping hydraulic fluid under pressure can have sufficient

force to penetrate the skin, causing serious injury. Before

applying pressure to the system, make sure all connections
are tightened, and lines, pipes and hoses are not damaged.
Fluid escaping from pinholes may be invisible. Do not use
your hands to search for suspected leaks. Instead, use a
piece of cardboard and wear protective eye wear such as
safety goggles.

If injured by escaping fluid, see a medical doctor at once.
Serious infection or reaction will result if proper medical
treatment is not administered immediately. This fluid can
produce gangrene or severe allergic reaction.

Battery Maintenance
Use caution when charging the battery or performing

maintenance on the battery and electrical system.
Use a voltmeter to check the state of the charge.
If using a battery charger make sure it is unplugged before

connecting or disconnecting the cables to the battery.
Batteries contain sulfuric acid electrolyte. Always wear

protective clothing and eye protection when servicing.
In case of electrolyte contact, rinse area with plenty of water

and seek medical attention.
Make sure the battery is charged in a well-ventilated location

so hydrogen gases that are produced while it is charging can
dissipate. Halt charging if battery exceeds 52°C (125°F).

Keep sparks, flames, and smoking material away from the
battery at all times. To avoid sparks, use care when
removing battery cables from their posts.

Disconnect the battery's ground cable before working on or
near any electrical parts.

Tire Maintenance

CAUTION: Separation of a tire and rim can
cause an explosion that could cause serious

injury or death.

Check the tires for low pressure, cuts, bubbles,
damaged rims, or missing lug bolts and nuts.

Always use a clip-on chuck with an extension

long enough to allow you to stand on one side
of the wheel while inflating the tires. Do not
stand directly in front of the tire while inflating.

Never weld or heat a tire and wheel assembly.
The heat can cause the air inside of the tire to

expand and result in a tire explosion. Welding
also can structurally weaken or deform the

wheel.

Always ensure the tires are inflated to the correct pressure.
Do not inflate the tires above the recommended pressure.

Make sure all hardware, especially the wheel nuts and bolts
have been tightened to the correct torque.

When removing a tire from the power unit, it is necessary to
support it with blocks or stands, not a hydraulic jack.

OPERATION

Break-in Period

• Operation of the mower within the first fifty hours can

be a major factor in determining the performance and
life of the engine and power unit.

• The engine may be operated at full RPM, but
excessive load should be avoided. If engine begins to
slow, due to excessive load, operate at a slower
ground speed while maintaining the engine speed.

• Check engine, pumps, and motors frequently during
break-in period. Watch for evidence of leakage of
fluids. Replenish levels as required and repair any
leaks that may have formed.

• Locate any nuts, bolts or screws that may have
loosened and tighten them as necessary. This is
especially true of the wheel retaining nuts.

• During break-in period observe control arm and
parking brake adjustments. Parking brake adjustments
may be necessary after the first few hours of operation.

• Keep area around the fuel tank filler clean and make
sure the gasoline is of correct octane and free of

contamination.

• Initial oil and oil filter change is after the first 8 hours of
use and every 100 hours after.

CAUTION: Proper maintenance practices are
required for safe operation. (See Maintenance

Schedule on page 17.)

Side-Discharge Mowers

DANGER: Without the discharge shield or a

complete grass collector installed, you and
others are exposed to rotating mower blades

and thrown debris. Contact with the mower
blades or flying debris could cause severe injury

or death.
The discharge deflector routes material down

toward the ground. Never remove the discharge
shield or operate the mower with a damaged
discharge deflector.

Never put your hands or feet under the mower.
Do not try to clear the mower discharge area or

mower blades without first turning the mower
PTO to off, turning the ignition key to off,
removing the key and disconnecting the battery

cable.

The mower has a pinned discharge shield that discharges
the clippings out of the side of the deck and onto the ground.

Uneven Terrain

WARNING: To avoid the loss of control and to

prevent overturning the mower, always across

slopes, never up and down.

Pass diagonally through sharp dips. Avoid sharp

drop offs completely to prevent the mower from

becoming hung up.
Keep the power unit steering control levers

forward when going downhill.

If the mower deck becomes clogged, back the unit out of the
uncut grass. If the mower will not clear itself, raise the deck,
shut off the engine, set the brake, remove the ignition key

and clean the bottom of the deck.
In medium and heavy cutting conditions, mow so the

discharged clippings will be AWAY from the uncut grass. In
light cutting, discharged clippings can be directed onto the
uncut grass, allowing them to be recut finer.

Tips For Efficient Mowing

CAUTION: Clear the area of people, pets, and

all visible debris before beginning mowing
operations.

Mowing blades should be checked regularly and kept sharp
to ensure the best lawn appearance.

Best results occur normally when the grass is maintained at
a height of 2-3 inches (50-80mm). It is best to cut the grass
often and not too short. To keep a healthy green lawn, do not
cut more than 1/3 of the overall grass blade height.

Mower engine speed while mowing should be at the
maximum rated RPM. This will ensure proper blade speed

for effective cutting and discharge of grass clippings.

Travel speed greatly affects mowing performance. Always
use a lower ground speed for slower mowing, rather than
lowering the engine RPM.

Mow often. Do not wait for the grass to get too tall. Short
grass clippings will disperse better and deteriorate faster.

Mowing areas with tall grass or weeds may require cutting at
maximum height of cut. After mowing once, recut the entire
area with the mower reset to the desired final height of cut.

Pre-plan mowing over uneven terrain so the grass will be
dry, minimizing wheel slippage and spinning, which will
damage the turf.

Before mowing, check the area to determine the best
procedure. Consider the grass type and height, and the type

of uneven terrain on which the mowing is to take place.
Avoid sudden starts and stops while traveling up or down

incline, and slow the ground speed while turning.

Grass Discharge

,_ WARNING: NEVER operate the mower with

The mower deck has been designed to provide maximum air
flow for an even discharge of grass clippings. When mowing
tall, or lush grasses, select a lower mower ground speed, or

reduce the width of cut, for the best discharge efficiency.
For the best lawn appearance, do not mow when the grass

is wet or heavy with dew. Wet grass could plug the discharge
area of the mower, create an unnatural load on the blades
and spindles, and damage the mower deck belt. Wet grass

will also leave unsightly clumps on the lawn.

the discharge shield in the raised position.

PARKING

To park the unit:

1. Bring the steering levers to neutral and then push them
out to the park position.

2. Turn off the PTO, stop the engine, lower the deck to
the ground and remove the ignition key.

IMPORTANT: When parking on any slope, be sure to chock
the wheels on the downhill side to prevent the unit from
sliding.

GB- 16

Moving the Unit with the Engine Off

If the mower engine stalls and will not restart, the unit can be
pushed or towed for short distances with the pump bypass

valves open. Do not exceed 5 m.p.h. (8 km/h) when towing.

IMPORTANT: The bypass valves must be opened two full

turns (maximum) before the unit is moved (see figure 11).

Be sure the bypass valves are closed before running the
mower again. Failure to fully close the bypass valves before

operation could result in hydraulic system damage.

Bypass Valves

TOWING

WARNING: Exercise care when turning the
mower while towing. The mower will turn more
sharply than the towed object.

IMPORTANT: Attempting to tow more than
300 pounds (137 kg) with the Ariens mower will
lead to premature parts failure and void the
warranty.

The mower is designed for towing in light duty applications
only. Do not attempt to tow more than 300 Ibs. (137 kg).
Tongue weight is not to exceed 30 Ibs (13.61 kg).

LOADING THE MOWER

WARNING: Exercise extreme caution when

loading and unloading the unit from a ramp.
Use only a single, full width ramp. If individual

ramps are necessary, use several to simulate a
single full width ramp. Use enough ramps to
create an unbroken ramp surface wider than

the unit.

Never exceed a 15 degree angle between the

ramps and the truck or trailer when loading the

mower.
Avoid sudden acceleration and deceleration of

the unit when loading and unloading the unit to
avoid the mower from tipping backward.

The loading ramp should be long enough that the angles
between the truck or trailer do not exceed 15 degrees. A
steeper angle may cause the mower deck components to
get hung up when moving the mower from ramp to truck or
trailer. If loading on or near a slope, position the truck or
trailer on the down side of the slope and the ramps should
extend up the slope. This will minimize the ramp angle. The
trailer or truck should be parked as level as possible to

facilitate smooth loading of the mower.

TRANSPORTING THE MOWER

WARNING: When transporting the mower,

make sure the steering control levers are in the

park position, the wheels have been blocked,
the machine has been securely fastened by
cables, chains or ropes, and the trailer has

been secured to the towing vehicle with safety
chains.

Use a heavy duty trailer or truck to transport the mower.
Make sure the trailer or truck has all of the necessary
lighting and markings as required by law.

WARNING: AVOID INJURY. Read and
understand entire Safety section before

proceeding.

Ariens Dealers will provide any service, parts or adjustments
which may be required to keep your unit operating at peak

efficiency. Should engine require service, contact an Ariens

GB - 20

Bleeding/Purging the Hydraulic System
IMPORTANT: Air in the hydraulic system is the primary

cause of hydraulic pump failures. Following hydraulic
system service or repair, the hydraulic system MUST be
correctly purged of trapped air before placing the mower
back in operation.

1. To bleed the system make sure the oil tank is full, the
oil must barely cover the fill baffle inside of the tank.

2. Raise the rear unit tires off the floor and place it on
suitable jack stands.

3. Open both pump bypass valves, one on each pump,
two full turns maximum.

4. Sitting in the operator's seat, start the engine and run it
at idle.

5. Slowly cycle the steering control levers full forward and
full reverse for 10 seconds in each direction, 5 or 6
times.

NOTE: The rear tires should rotate, but they'll not be under
load.

6. Shut off the engine, check and add hydraulic oil as
necessary.

7. Close the bypass valves on both pumps. Do not over
tighten.

8. Sitting in the operator's seat, start the engine and run it
at idle.

9. Slowly cycle the steering control levers full forward and
full reverse, 5 or 6 times.

NOTE: It may be necessary to repeat purging procedures
until all air is vented out of the hydraulic system. When the
Pump moves forward and reverse at normal speed and the
reservoir oil remains at a constant level, purging is complete.

IMPORTANT: The rear tires are now rotating under power.
Do not touch or contact them. If they do not rotate after 2-3
cycles, stop immediately. There may still be air in the
system. Let the pumps cool and try purging again from
Step 1.

The Unloader Valve (1)will allow for the removal of fine dirt

and dust from the canister body (3) without disassembly.

While in operation, this valve will suck closed at 1/3 to 1/2
throttle.

• With the engine shut off, squeeze the valve by hand to
release dust and debris.

• In very dusty operating conditions, the valve may have
to be opened every 2 to 3 hours.

Remove the air cleaner cover and make a general
inspection of the entire assembly. If it is unusually dirty or if
dirt build-up is easily visible on the inside of the canister
body, the entire assembly, including the inlet hose, must be
removed from the carburetor and engine.

With the air cleaner removed from the engine, and with the

cartridges and gaskets removed, wash the hard parts with
cleaning solvent and blow them dry with compressed air. DO
NOT wash the air cleaner cartridges.

NOTE: If canister gaskets are broken or missing, BOTH air
cleaner elements MUST be replaced.

Inspect and clean the primary air cleaner cartridge (5)
assembly every 25 hours. Replace the paper element yearly

or every 250 hours, whichever comes first.
The outer cartridge is cleaned by rolling and "tapping" it on a

hard surface. If the paper pleats are punctured or torn, the
element must be replaced.

Replace the inner cartridge (6) yearly or every 250 hours

whichever comes first.

IMPORTANT: DO NOT attempt to clean the secondary
element. This filter element must be replaced if it is
unusually dirty or damaged.

NOTE: Operation in dusty conditions may require more fre-
quent maintenance of the primary and secondary air cleaner
cartridges.

CAUTION: Do not use pressurized air to clean
paper element.

FUEL SYSTEM SERVICE

CAUTION: Fuel vapors are explosive and
flammable. Do not smoke while handling fuel.

Keep fuel away from flames or sparks. Shut off
engine before servicing. Always work in a
well-ventilated area. Clean up spilled fuel

immediately.

Be sure the engine is stopped, the steering
control levers are in the park position and the

key is removed before making these repairs.

Be sure to inspect the fuel lines periodically.
The lines are subject to deterioration and wear.

Fuel could leak out onto a running engine and
cause a fire.

WARNING: Improper use of solvents can

result in fire or explosion. Do not use gasoline
or low flash point solvents to clean the fuel filter
and/or the fuel pump. Clean only in a
well-ventilated area away from sources of
sparks or flame, including any appliances with
a pilot light.

IMPORTANT: Special care should be taken when the fuel
lines are removed for maintenance or repair. Close both
ends of the fuel line with a piece of paper or a clean cloth to
prevent dust or dirt particles from contaminating the fuel.
Even a small amount of dust or dirt can cause premature

wear or failure of fuel components.

The fuel line connections are composed of rubber and they

will age regardless of the service period. If there is any

deterioration of the fuel lines or clamps, replace them.
Check the fuel filter regularly. If it is clogged by debris or

contaminated with water, replace it.
The fuel filter cannot be disassembled. If the fuel filter

becomes clogged, replace it with a new one.

,

Park the machine safely in a well-ventilated area.

fins and inside the engine shrouds to remove grass, chaff or

dirt clogging the cooling system and causing overheating.

,_ CAUTION: Do not run the engine before all

cooling system parts are reinstalled to keep the
cooling and carburetion as intended.

2. Clean the electrodes by scraping with a wire brush to
remove carbon deposits.

3. Inspect for cracked porcelain or other wear and
damage. If any wear or damage is evident, replace
with a new spark plug.

4. Check the spark plug gap and reset if necessary. The
correct gap should be .030 inches (.75 mm). To
change the gap, bend only the side electrode using a
spark plug tool.

GB - 26

TIRE AND WHEEL SERVICE

CAUTION: Separation of a tire and rim can

cause an explosion that could cause serious
injury or death.

Check the tires for low pressure, cuts, bubbles,
damaged rims, or missing lug bolts and nuts.

Always use a clip-on chuck with an extension
long enough to allow you to stand on one side
of the wheel while inflating the tires. Do not
stand directly in front of the tire while inflating.

Never weld or heat a tire and wheel assembly.
The heat can cause the air inside of the tire to

expand and result in a tire explosion. Welding
also can structurally weaken or deform the

wheel.

Visually inspect the tires before each use. Do not run the
tires under- or over-inflated which can cause tire damage.
The correct tire pressure for the front tires is 20 p.s.i.

(82.7 kpa) and rear wheels is 12 p.s.i. (137.9 kpa) (see

figure 25).
When reinstalling the wheel after service, be sure to torque

the nuts to 75 ft. Ibs. (101 N-m). Drive 200-250 yards and
then re-torque.

To sharpen the blades, remove the blades by inserting a
block of wood and turning the blade bolt counter clockwise
(see figure 26).

Stop Block

Figure 26 OE3356

,_ CAUTION: Always wear safety eye protection

Be sure to wear a thick glove or wrap the blade in a towel to
protect your hands from being cut. Insert the blades in a vise

or wrap them in a towel before handling them.

Inspect the blades daily for straightness, sharpness, and
balance. Replace the blades if they are cracked, worn, bent

or out of balance.

NOTE: Keep blades sharp. Mowing with dull blades will
cause poor cut performance. It will also put additional strain

on the engine by slowing the mower cutting speed.

IMPORTANT: When sharpening blades, be sure to grind the
same amount on each side. Unbalanced blades will cause

excessive vibration and could cause the spindles to wear
prematurely.

Check the blade balance by inserting a horizontal rod

through the center hole of the blade. The heavy side of the

blade will drop down. Sharpen the heavy side of the blade
until the blade is balanced, see figure 28.

sprayers.

BELTS

Inspect the belt pulley grooves and flanges for wear. A new

belt, or one in good condition, should not contact the bottom
of the pulley groove. Replace the belt when the belt touches
the bottom of the groove otherwise the belt will slip

excessively.
Always use caution when changing a belt. Never pry a belt

on to a pulley.
Always keep oil and grease away from the belts and never

use belt dressings.

Belts should be checked regularly, and replaced at

approximately 250 hour intervals. Belts should also be

replaced any time the belt(s) show evidence of cracking,

missing pieces, friction burns from slipping, or other extreme

damage. Small cracks or fabric polishing are normal.
