Throttle Control and Choke Control

Choke Control
The choke control is used for cold starts to provide the engine with a richer fuel mixture.
The choke control is combined with the throttle control. To engage the choke, the throttle control is moved past the max RPM setting to the choke position.
Do not use the choke when starting a warm engine.
Throttle Control
The throttle control regulates the engine speed and thereby the rate of rotation of the blades, assuming the control for engaging the mower deck is pulled forward.
In order to increase or decrease the engine speed, the control is moved forward or backward respectively.
Avoid idling the engine for long periods, as there is a risk of the spark plugs fouling.
For best mower performance, USE FUll THROTTlE WHEN MOWING.

Fuel Tank

The machine has one fuel tank. The tank volume is 5.3 gallons / 20 liters.
The engine should run on a minimum of 87-octane unleaded gasoline (no oil mix). Also see Technical Data concerning methanol and ethanol fuels.
When operating in temperatures below 32° F. (0° C.), use fresh, clean winter grade gasoline to help insure good cold weather starting.
WARNING!
Gasoline is highly ammable. Observe caution and ll the
tank outdoors (see the safety instruction).
8011-418
Fuel tank
WARNING! The engine and the exhaust
system, become very hot during operation.
Risk for burns if touched. Allow engine and exhaust system
to cool at least two (2) minutes before refueling
WARNING!
Fill to bottom of ller neck. Do not overll. Wipe off any spilled oil
or fuel. Do not store, spill or use
gasoline near an open ame.
IMPORTANT INFORMATION Experience indicates that alcohol
blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage Instructions for additional information. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur.

OPERATION

Gearbox

The gear drive machines have a 5-speed gearbox. The gear selector is placed under the control panel.
Only shift gear when the machine is standing still and on level ground.

Running

Depress one operator presence lever and shift 1. transmission to the desired gear.
Unlock the motion control levers by pushing the 2. neutral bail down, out of the neutral slots. Slowly release both levers at the same time to begin forward motion. The steering system of this mower uses individual right and left motion control levers on the handle bars. Squeezing the lever will reduce tension on the wheel drive belt, eliminating power to that wheel. With the opposite wheel still under power, a turn is accomplished.

Mowing Tips

Observe and mark rocks and other xed objects in
order to avoid collisions.
Properly level the cutting deck for best mowing performance. The blades should be parallel to the ground or slightly tipped down in the front.
Use only sharp blades. Check tire pressure. Different pressure can cause
uneven mowing results. Use the left hand side of the deck for trimming. Drive so 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
rst two patterns in opposite direction.
Begin with a high cutting height and reduce it until the desired mowing result is attained.
Cut the average lawn to 2½" (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 15 cm (6") in height should be mowed twice. Make the
rst cut relatively high; the second to the desired
height. Use a high engine speed (the blades rotate
rapidly) and low speed (the machine moves slowly) for the best mowing results. If the grass is not too long and dense, the driving speed can be increased without noticeably depreciating the mowing result.
Mowing often for obtaining the nest lawn. The
mowing becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher driving speed can be used without poorer mowing results.
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 spray high pressure spray directly on top of spindles. Avoid getting engine too wet.
8011-409
Mowing pattern
WARNING! Never drive the machine on
terrain that slopes more than 10 degrees.
Mow slopes up and down, never side to side. Avoid sudden directional changes.

Stopping

Emergency stop

Release both hands from the operate 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 drive levers rmly against handle grips and
hold them securely in place. Use thumbs to lift the neutral bail up into the neutral slot. Stop engine by pulling throttle control back and then shut off the key switch.

Normal operating stop

Pull both drive levers (traction levers) rmly toward
the handle grips to stop forward motion. Use thumbs to lift neutral bail into the neutral slots. Move the throttle control to the slow position. Move blade engagement control to the off position. Move shift lever to the neutral position. Stop engine.

Stopping the Engine

If the engine has been worked hard, allow it to idle a minute in order to attain normal operating temperature before stopping it. Avoid idling the engine for longer periods, as there is a risk of the spark plugs fouling.

STORAGE

Winter Storage

At the end of the mowing season (or if it will not be in use for longer than 30 days), the machine should be readied for storage. 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 as regards to the sticky residues that can occur during storage.
Add stabilizer to the fuel in the tank or in the storage
container. Always use the mixing ratios specied 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 ames, sparks, or a pilot
light such as in a boiler, hot water tank, clothes drier, etc. Handle the fuel with care. It is very
ammable and can cause serious
personal injury and property damage. Drain the fuel into an approved container outdoors
and far away from open ame.
Never use gasoline for cleaning. Use a degreaser and warm water instead.
To ready the machine for storage, follow these steps:
Thoroughly clean the machine, especially
1. under the mower deck. Touch up damage to the paint and spray a thin layer of oil on the underside of the mower deck to avoid corrosion.
Inspect the machine for worn or damaged 2. parts and tighten any nuts or screws that may have become loose.
Change the engine oil; dispose of properly.3. Empty the fuel tanks or add a fuel stabilizer. 4.
Start the engine and allow it to run until the carburetor is drained of fuel or the stabilizer has reached the carburetor.
Remove the spark plug and pour about a 5. tablespoon of engine oil into the cylinder. Turn over the engine so that the oil is evenly
distributed. Ret the spark plug.
lubricate all grease zerks, joints, and axles.6. Store the machine in a clean, dry place and 7.
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 checkup at an authorized service workshop
is a good way to ensure that the machine performs its best the following season.
