SAFETY INSTRUCTIONS

Driving on Slopes

Driving on slopes is one of the operations where the risk is greatest that the driver will lose controlor the machine willtip over,which can result in serious injury or death. All slopes require extra caution. If you cannot reverse up a slope or if you feel unsure, do not mow the slope.

Do as follows

• Remove obstacles such as stones, tree branches, etc.

• Watch out for and avoid driving over furrows, holes, and bumps. On uneven terrain, the machine can tip more easily. Long grass can hide obstacles.

• Mow up and down, not side-to-side.

• If machine stops while going uphill, disengage blades and back down slowly.

• Drive evenly and slowly. Use small movements of the motion controls.

• Be extra cautious with any additional equipment, which can alter the machine’s stability.

Do not

• Do not make sudden changes in speed or direction.

• Do not drive the machine on terrain that slopes more than 10°.

• Do not mow near verges, ditches, or banks. The machine can suddenly spin around if a wheel goes over the edge of adroporditch,orifanedgegivesway.

• Do not mow wet grass. It is slippery,and the tires can lose their grip, so that the machine slides.

• Avoid unnecessary turns on slopes, and if it proves necessary, turn slowly and gradually downward, if possible.

• Only use sharp blades.

• Check tire pressure. Different pressure can cause uneven mowing result.

• The left hand side of the deck should be used for trimming.

• Drive so that clippings are discharged onto the area that has been cut. Have the cut area to the right of the mower. This will result in more even distribution of clippings and a more uniform cut. To avoid clippings spraying on roads etc, mow the first two patterns in opposite direction.

• Begin with a high cutting height and reduce it until the desired mowing result is attained.

The average lawn should be cut to 2 1/2" (64 mm) during the cool season and to over 3" (76 mm) during the hot months. For healthier and better looking lawns, mow often after moderate growth.

For best cutting performance, grass over 6" (15 cm) in height should be mowed twice. Make the first cut relatively high; the second to the desired height.

• The mowing result will be best with a high engine speed (the blades rotate rapidly) and l ow speed (the machine moves slowly).If the grass is not too l ong and dense, the driving speed can be increased without noticeably depreciating the mowing result.

• The finest lawns are obtainedby mowing often. The m owing becomes more even and the grass clippings more evenly distributedover the mown area. The total time taken is not increased as a higher drivingspeed can beused without poorer mowing results.

WARNING! Clear the lawn of stones and

other objects that can be thrown out by the blades.

8011-409

Mowing patterns

English-27

• Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and the grass clippings will fasten under the cowling.

• Hose the mower deck with water after each use. Hose especially underneath. Do not sprayhigh pressure spray directly on top of spindles.

• Avoid getting engine too wet.

WARNING! Never drive the machine on

terrain that slopes m ore than 10°. Mow sl opes up and down, never side-to-side. Avoid sudden directional changes.

Oil Recommendations

Using the proper type and weight of oil in the crankcase is extremely important. So is checking oil daily and changing oil regularly. Failure to use the correct oil, or using dirty oil, causes premature engine wear and failure.

Oil Type

Use high quality detergent oil of API (American Petroleum Institute) service class SG, SH, SJ or higher. Select the viscosity based on the air temperature at the time of operation.

IMPORTANT INFORMATION Using other than service class SG, SH, SJ

or higher oil or extending oil change intevals longer than recommended can cause engine damage.

IMPORTANT INFORMATION Synthetic oils meeting the listed

classfications may be used with oil changes performed at the recommended intervals. However to allow piston rings to properly seat, a new or rebuilt engine should be operated for at least 50 hours using standard petroleum based oil before switching to synthetic oil.

STORAGE

Storage

Winter Storage

At the end of the mowing season, the machine should be readied for storage (or if i t will not be in use for longer than 30 days). Fuel allowed to stand for long periods of time (30 days or more) can leave sticky residues that can plug the carburetor and disrupt engine function.

Fuel stabilizers are an acceptable option to prevent sticky residues during storage. Add stabilizer to the fuel in the tank or in the storage container. Always use the mixing ratios specified by the manufacturer of the stabilizer. Run the engine for at least 10 minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if you have added stabilizer.

WARNING! Never store an engine with fuel

in the tank indoors or in poorly ventilated spaces where fuel vapor can come in contact with open flames, sparks, or a pilot light such as in a boiler, hot water heater, clothes drier, etc. Handle the fuel with care. It is very flammable and careless use can cause serious personal injury and property damage. Drain the fuel into an approved container outdoors and far away from open flame. Never use gasoline for cl eaning. Use a degreaser and w arm water instead.

To ready the machine for storage, follow these steps:

1. Thoroughly clean the machine, especially under the mower deck. Touch up damage to the paint and spray a thin layer of oil on the undersideof the mower deck in order to avoid corrosion.

2. Inspect the machine for worn or damaged partsand tighten any nuts or screws that may have become loose.

3. Change the engine oil; dispose of properly.

4. Empty the fuel tanks or add a fuel stabilizer. Start the engine and allow it to run until even the carburetor is drained of fuel or the stabilizer has reached the carburetor.

5. Remove the spark plugs and pour about a tablespoon of engine oil into each cylinder. Turn over the engine so that the oil is evenly distributed and then refit the spark plugs.

6. Lubricate all grease zerks, joints, and axles.

7. Store t he machine in a clean, dry place and cover it for extra protection.

Service

When ordering spare parts, please specify the purchase year, model, type, and serial number.

Always use genuine Husqvarna spare parts. An annual check-up at an authorized service

workshop is a good way to ensure that your machine performs i ts best the following season.
