Check grass bag for wear, damage, and/or deterioration. Replace only with Ariens original equipment replacement parts for safety. To reduce fire hazard and overheating, keep equipment free of grass, leaves, debris or excessive lubricants.

Use extra care when approaching blind corners, shrubs, trees, or other objects which may obscure vision. DO NOT mow at too fast a rate. DO NOT change engine governor setting or overspeed the engine. Do not operate mower on gravel or loose material such as sand. Stop mower when crossing drives, walks, or roads to prevent damage or injury from thrown objects. DO NOT pull mower backwards unless absolutely necessary. Look down and back, especially for small children, before and while moving backwards. On self-propelled models, releasing wheel drive control must stop mower’s forward movement. If this feature fails to operate, disconnect spark plug wire and repair before using unit. On self-propelled models, wheel drive must be disengaged when starting engine. DO NOT operate on steep slopes. NEVER leave unit unattended on a slope. Chock wheels if parking on a slope. Mow across the face of slopes, never up and down. Be especially cautious when changing direction on slopes. This product is equipped with an internal combustion engine. DO NOT use on or near any unimproved, forest or brush covered land unless the exhaust system is equipped with a spark arrestor meeting applicable local, state or federal laws. A spark arrestor, if used, must be maintained in effective working order by the operator. See your Ariens Dealer or engine manufacturer’s service center. Fuel is highly flammable and its vapors can explode. ONLY use approved fuel containers.
· NO Smoking! · NO Sparks! · NO Flames! · Allow engine to cool before filling fuel
tank. 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. When practical, remove gas-powered equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment on a trailer with a portable container, rather than from a gasoline dispenser nozzle.

GB – 8

Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lockopen device. Check fuel supply before starting engine. DO NOT fill gasoline tank indoors, when engine is running, or while engine is hot. Allow engine to cool several minutes before removing fuel cap. DO NOT overfill. Allow about 1/4″ (6 mm) of tank space for fuel expansion. Replace gasoline tank cap securely and clean any spilled fuel before starting engine. If fuel is spilled on clothing, change clothing immediately. NEVER store fuel inside where there is an open flame, such as a water heater. ALWAYS drain fuel outdoors away from ignition sources. ALWAYS shut off engine, and remove key, and close fuel shutoff valve when transporting unit on a truck or trailer. Avoid Electric Shock. DO NOT disconnect wire from spark plug while engine is running. Do NOT put battery in fire or mutilate. Explosive Gases! NO flames, NO sparks, NO smoking, near battery. Poisonous battery fluid contains sulfuric acid. Contact with skin, eyes or clothing can cause severe chemical burns. ALWAYS wear safety glasses and protective gear near battery. 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. Charge batteries in an open, well-ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting battery. Wear protective clothing and use insulated tools. Accidental engine start up can cause death or serious injury. Except where specifically recommended, ALWAYS stop engine, remove key (electric start models), wait for moving parts to stop, allow parts to cool and disconnect spark plug wire before inspecting, servicing, adjusting or repairing unit. Keep mower free of grass, leaves, or other debris build-up.

Keep equipment in good condition. Maintain or replace safety and instruction labels, as necessary. Follow engine manufacturer’s safety instruction when servicing engine. Check all hardware at regular intervals, especially blade attachment bolts. Keep all hardware properly tightened. An extension spring, when extended, stores energy and can be dangerous. Always use tools specifically designed for installing or removing an extension spring. Always compress or extend springs slowly. Before tipping unit, remove fuel and battery (if equipped). Use extra care when loading or unloading unit onto trailer or truck. Ensure all wheel blocks, jack stands and tie downs will support unit during maintenance. Replace worn-out mufflers immediately. Continued use could result in fire or explosion. Sharp edges can cut or amputate fingers or a hand. Wrap blade or wear sturdy gloves to service. Only replace blades. NEVER straighten or weld blades. Use only replacement parts designed for your unit. See your Ariens Dealer. Allow engine to cool before storing in any enclosure. ALWAYS clean unit before extended storage. See engine manual for proper storage. DO NOT store unit inside a building with fuel in the fuel tank where any ignition sources are present. Use only accessories which have been approved by Ariens and are properly installed. Use only accessories or attachments that are designed for your unit and that can be used safely on your terrain. Check attachments frequently and replace worn or damaged components with manufacturer’s recommended parts.

WHEEL DRIVE CONTROL ADJUSTMENT (self-propelled models)
See Figure 16. NOTE: When the wheel drive control is disengaged, the gap between the friction disc and the aluminum drive plate should be approximately .030″ (0.7mm). See Figure 16.
Friction Disc
Aluminum Drive Plate
Approx. .030″ (0.7mm)
Figure 16
Check the adjustment with the engine off and with the engine on:
1. With the engine off and the wheel drive control disengaged, push the mower forward in both fast and slow speed settings. If the mower pushes freely, the gap between the friction disc and aluminum drive plate is sufficient. If the mower is difficult to push or the rear wheels drag, increase the gap between the friction disc and aluminum drive plate.
2. With the engine on, the mower should start moving as soon as the wheel drive control begins to pull on the cable. If the wheel drive control requires a long travel before the mower begins to pull, decrease the gap between the friction disc and aluminum drive plate.
To increase the gap between the friction disc and the aluminum drive plate:
1. Loosen the lower cable nut on the wheel drive control cable, and then tighten the upper cable nut against the adjuster bracket. See Figure 17.

GB – 22

To increase the gap, loosen the lower cable nut.
Then tighten the upper cable nut against the bracket.
Figure 17 To decrease the gap between the friction disc and the aluminum drive plate:
