Disengage blade(s) when not mowing. Shut off engine and wait for all parts to come to a complete stop before cleaning the machine, removing the grass catcher, or unclogging the discharge guard.

Know the weight of loads. Limit loads to those you can safely control and the unit can safely handle.

Operating Conditions

Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine, seek shelter.

ALWAYS check overhead and side clearances carefully before operation.

Watch for traffic when operating near or crossing roadways.

Clear the area of objects such as rocks, wire, toys, etc., which could be thrown by the blades.

Check for weak spots on docks, ramps or floors. Avoid uneven work areas and rough terrain. Stay alert for hidden hazards or traffic.

Use care when approaching blind corners, shrubs, trees or other objects that may obscure vision.

Dust, smoke, fog, etc. can reduce vision and cause an accident.

Operate machine only in daylight or good artificial light.

Slope Operation

Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, DO NOT mow it.

DO NOT operate on slopes of more than 15°.

Mow up and down slopes, not across. ALWAYS keep the machine in gear when

going down slopes. DO NOT shift to neutral and coast downhill.

Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

DO NOT mow on moist or wet grass. Tires may lose traction causing a loss of control.

Use extra care while operating machine with grass catchers or other attachments; they can affect the stability of the machine. DO NOT use on steep slopes.

Keep all movements on the slope slow and gradual. DO NOT make sudden changes in speed or direction, which could cause the machine to roll over.

Avoid starting, stopping, or turning on a slope. If the tires lose traction, disengage the blade(s) and proceed slowly straight down the slope.

Operation on slopes may lead to loss of steering control. When operating on slopes be prepared to react to an emergency situation:

• Return steering levers to neutral position.

• Immediately set parking brake.

• Turn off PTO and engine. DO NOT try to stabilize the machine by

putting your foot on the ground.

EN - 8

DO NOT park on slopes unless necessary. When parking on slope ALWAYS chock or block wheels. AL WAYS set parking brake.

Choose a low ground speed so you will not have to stop or shift while on a slope.

DO NOT mow near drop-offs, ditches, or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge caves in.

DO NOT bypass transmission or allow transmission to free-wheel when on a slope.

Fuel

T o avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

Ethanol blends must not exceed E10. Higher ethanol content may cause your machine to run hotter and damage your engine.

Replace fuel cap securely and clean up spilled fuel before starting engine.

Extinguish all cigarettes, cigars, pipes and other sources of ignition.

Use only an approved gasoline container. NEVER store the machine or fuel container

where there is an open flame, spark or pilot light such as on a water or space heater or other appliances.

NEVER fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. ALWAYS place containers on the ground away from your vehicle before filling.

NEVER fuel the machine indoors. NEVER remove gas cap or add fuel with the

engine running. Allow engine to cool before fueling.

Fuel is highly flammable and its vapors are explosive. Handle with care. Use only an approved gasoline container with an appropriately-sized dispensing spout.

NO smoking, NO sparks, NO flames. Remove gas-powered equipment from the

trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a gasoline dispenser nozzle.

Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until the fueling is complete. DO NOT use a nozzle lock-open device.

NEVER overfill fuel tank. Replace gas cap and tighten securely.

If fuel is spilled on clothing, change clothing immediately.

Towing

Follow the manufacturer’s recommendations for weight limits for towed equipment and towing on slopes.

NEVER allow children or others in or on towed equipment.

Tow only with a machine that has a hitch designed for towing. DO NOT attach towed equipment except at the hitch point.

On slopes, the weight of the towed equipment may cause loss of traction and loss of control.

Travel slowly and allow extra distance to stop.

Accessories

Follow the manufacturer’s recommendation for wheel weights or counterweights

Check grass catcher components and the discharge guard frequently and replace with the manufacturer’s recommended parts, when necessary.

Use only Ariens Company-recommended attachments that are appropriate to your use and can be used safely in your application.

Batteries

Avoid electric shock. Objects contacting both battery terminals at the same time may result in injury and unit damage. DO NOT reverse battery connections.

Reverse connections may result in sparks which can cause serious injury. ALWAYS connect positive (+) lead of charger to positive (+) terminal, and negative (-) l ead to negative (-) terminal.

ALWAYS disconnect negative (-) cable FIRST and positive (+) cable SECOND. ALWAYS connect positive (+) cable FIRST, and negative (-) cable SECOND.

Explosive gases from battery can cause death or serious injury. Poisonous battery fluid contains sulfuric acid and its contact with skin, eyes or clothing can cause severe chemical burns.

EN - 9

No flames, No sparks, No smoking near battery.

ALW AYS wear safety glasses and protective gear near battery. Use insulated tools.

ALWAYS keep batteries out of reach of children.

Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the state of California to cause cancer and reproductive harm. Wash hands after handling.

Service

The use of non-genuine replacement parts or accessories could adversely affect machine operation and safety.

Do not change engine governor setting or overspeed the engine.

Maintain or replace safety and instruction labels as necessary.

Keep unit free of debris. Clean up oil or fuel spills.

ALWAYS block wheels and know all jack stands are strong and secure and wi ll hold weight of unit during maintenance.

Release any pneumatic or hydraulic pressure from components slowly.

NEVER attempt to make any adjustments to unit while engine is running (except where specifically recommended). Stop engine, remove key and spark plug wire and wait for all moving parts to stop before servicing or cleaning.

Lower cutting deck unless a positive mechanical lock is used.

Allow engine to cool before servicing. Moving parts can cut or amputate fingers or

a hand. On multiblade mowers, rotation of one blade will cause all blades to rotate.

NEVER weld or straighten mower blades. NEVER make adjustments or repairs with

the engine running. Mower blades are sharp. Wrap the blade or

wear gloves, and use extra caution when servicing them.

ALWAYS keep body and hands away from pin holes or nozzles which eject hydraulic fluid under pressure.

Transporting Unit

Use extra care when loading or unloading the machine into a trailer or truck.

Secure unit chassis to transport vehicle. NEVER secure from rods or linkages that could be damaged.

DO NOT transport machine while engine is running.

ALWAYS turn off power to attachment and shut off fuel when transporting unit.

LEVEL AND PITCH MOWER DECK

IMPORTANT: Make sure unit is on a flat,

level surface and that tires are inflated to the recommended pressures.

Check Blade Level and Pitch

1. Raise deck to 3 1/2" (8.9 cm) cutting height.

2. Stop engine, remove key and wait for moving parts to stop and for hot parts to cool.

3. Engage parking brake.

See Figure 50.

4. Position mower blades so ends point left to right across the width of the deck.

5. Measure the distance between the ground and the cutting edge of the left and right blades. If the measurements are not within 4.7 mm (3/16") of each other, level the deck. See Level and Pitch Mower Deck on page 35.

If the front measurement is not 3.2 mm (1/8") lower than the rear measurements, adjust the blade pitch. See Adjust Blade Pitch on page 36.

Level Mower Deck

See Figure 52.

1. Lower the high side of deck: a. Loosen jam nuts against deck-

leveling links.

b. Turn adjustment bolts

counterclockwise.

c. Measure distance between the

ground and cutting edges of left and right blades. Continue adjustment if necessary.

d. Tighten jam nuts against deck-

leveling links.

2. Raise the low side of deck: a. Loosen jam nuts against deck-

leveling links. b. T urn adjustment bolts clockwise. c. Measure distance between the

ground and cutting edges of left and

right blades. Continue adjustment if

necessary. d. Tighten jam nuts against deck-

leveling links.

See Figure 51.

6. Position mower blades so ends point front to back and measure the following:

• At the front of the deck, measure the

distance between the ground and the cutting edge of the middle blade.

• At the rear of the deck, measure the

distance between the ground and the cutting edge of the left and the right blades.

EN - 35

Adjust Blade Pitch

IMPORTANT: Side-to-side deck heights

MUST remain level even after completing pitch adjustment.

IMPORTANT: Pitching the front of the blades lower than the rear provides a balance between cut quality and the power needed to cut grass. Certain cutting conditions require the deck rear to be pitched lower than the front. Positioning the deck this way requires more engine power but can provide better cut quality.

1. Increase forward pitch:

a. Loosen jam nuts against all deck-

leveling links.

b. Turn front adjustment bolts

counterclockwise to lower deck front.

c. Turn rear adjustment bolts clockwise

to raise deck rear.

d. Check adjustment. S ee Check Blade

Level and Pitch on page 35.

e. Tighten jam nuts against deck-
