Reversing
1. Depress one operator presence lever and pull the ground speed lever fully back.
2. Unlock the motion control levers by pushing the neutral bail down out of the neutral slots. Slowly push both motion control levers towards the handle at the same time to begin a straight line backward motion.
3. The steering system of this mower uses individual right and left motion control levers on the handle bars. Squeezing one motion control lever more than the other will reduce the flow of oil from the hydro pump to its wheel motor. The speed of the wheel is reduced. With the both wheels still under power, a turn is accomplished.
4. To stop backward travel, set both levers backinto their stop positions and lock the position with neutral bail.

T o operate on hills
To operate on slopes is a dangerous mowing job. Read the Safety Instructions section “Driving on Slopes” on page 8.
WARNING! Do
not drive up or down hills with slopes greater than 10 degrees. And do not drive across any slopes.
The slowest speed possible should be used before starting up or down hills.
Avoid stopping or changing speed on hills.
Make all turns slowly.

Mowing Tips
OPERATION
Observe and mark rocks and other fixed objects in order to avoid collisions.
The cutting deck should be properly leveled for best mowing performance. The blades should be parallel to the ground or slightly tipped down in the front.
Only use sharp blades.
Check tire pressure. Different pressure can cause uneven mowing results.
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 l ooking lawns, mow often after moderate growth.
For best cutting performance, grass over 6" (15 cm) i n 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 t oo long 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-28
Page 31
OPERATION
Avoid mowing wet lawns. The mowing result is poorer because the wheels sink into the soft lawn, clumps build, and the grass clippings fasten under the cowling.
Hose the mower deck with water after each use. Hose especially underneath.
Do not spray high pressure spray directly on top of spindles.
Avoid getting engine too wet.
WARNING! Never drive the machine on
terrain that slopes more than 10°. Mow sl opes up and down, never side-to-side. Avoid sudden directional changes.
8011-514
Clean mower deck after each use
Stopping
Emergency stop
Release both hands from the operator presence lever handles. When both operator presence levers return to their outer position, the engine will quit and the mower will stop.
or Pull both motion control levers firmly against handle
grips and hold them securely in place. Use thumbs to lift the neutral bail up i nto the neutral slot. Then stop engine by pulling throttle control back and shut off the key switch.

STORAGE

Storage
Winter Storage
At the end of the mowing season, the machine should be readied for storage (or if it 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 a sticky residue that can foul the carburetor and disrupt engine function.
Fuel stabilizers are an acceptable option as regards 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 tank, 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 cleaning. Use a degreaser and warm 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 f uel 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 the 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.
