(if any). If a spark arrester is used, it should be maintained in effective working order by the operator. A spark arrester for the muffler is available through your authorized Husqvarna dealer. IMPORTANT INFORMATION The parking brake is not sufficient to lock the machine in place during transport.
Controls This operator’s manual describes the Husqvarna Walk-Behind Mowers WG3213P, WG3613P and WG4815P. The machines are fitted with a Kawasaki or Kohler four-stroke V- Twin engine, for data see “Technical data” on page 60. Transmission from the engine is made via two V-belts, one for each wheel.
Pull the recoil starter grip slowly until you feel compresion, then pull it briskly. Normally this engine will not backfire. If you get backfires, contact your Husqvarna dealer for service. 2. Ignition Switch The ignition key switch is placed on the control panel.
3. Motion control levers The machine’s speed and direction are continuously variable using the two motion control levers. When both controls are in the neutral position, the machine stands still. The controls can be locked in neutral position by the thumb latches. By releasing both controls an equal amount, the machine moves in a straight line forward.
CONTROLS 5. Choke and Throttle Control Choke Control The choke control is combined with the throttle control. To engage the choke, the throttle control is moved past the max rpm setting to its choke position. Do not use the choke when starting a warm engine.
7. Thumb Latch The thumb latches are used to lock the motion control levers in their neutral position e.g. when starting the engine. Lock the motion control levers by pulling the thumb latches backward. Unlock the motion control levers by pushing the thumb latches forward.
9. Refueling The machine has one fuel tank. The tank volume is 5.3 Gallons / 20 liters. The engine should be run on a minimum of 87-octane unleaded gasoline (no oil mix). See “Technical data” on page 60 concerning methanol and ethanol fuels. WARNING! Gasoline is highly flammable.
10. Fuel Shut-off Valve The fuel shut-off valve is placed on the fuel line below the fuel tank. The valve has two positions; ON and OFF. The figure shows the valve in the closed OFF position. IMPORTANT INFORMATION Close fuel valve at the end of each mowing job.
Operation WARNING! Be thoroughly familiar with all controls, their function and how to operate them before operating the mower. Before Starting • Read the sections “Safety Instructions” on page 7, and “Controls” on page 14, before starting the machine. • Perform the daily maintenance before starting (see “Maintenance Schedule”...
Starting the Engine WARNING! Never run the engine indoors, in enclosed or poorly ventilated spaces. Engine exhaust fumes contain poisonous carbon monoxide.

Mowing Tips • 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.
Page 30
• 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.
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. Pull both motion control levers firmly against handle grips and hold them securely in place. Use thumb latches to lock both motion control levers in neutral positions.
Stopping the Engine Allow the engine to idle a minute in order to attain normal operating temperature before stopping it, if it has been worked hard. Avoid idling the engine for longer periods, as there is a risk of the spark plugs fouling. When the machine is standing still, activate the parking brake by moving the thumb latches to the park brake position.
Adjustment of cutting height The cutting height can be adjusted by three methods: • Moving spacers between the upper side and the lower side of the caster swivel according to "Cutting height table". For instruction, see below. • Moving spacers between the upper side and the lower side of the blades according to "Cutting height table".
OPERATION Moving Machine by Hand In order for the machine to be moved with the engine turned off, make sure the gear shift lever is in neutral position. Release the parking brake. 8011-482 Gear shift lever in neutral position English-...
Maintenance Maintenance Schedule The following is a list of maintenance procedures that must be performed on the machine. For those points not described in this manual, visit an authorized service workshop. An annual service carried out by an authorized service workshop is recommended in order to maintain your machine in the best possible condition and to ensure safe operation.

Ignition System The engine is equipped with an electronic ignition system. Only the spark plugs require maintenance. For recommended spark plugs, see Technical Data. Remove the ignition cable boot and clean around the spark plug. Remove the spark plugs with a spark plug socket wrench.
Checking the Safety System The machine is equipped with a safety system that prevents starting or driving under the following conditions. The engine can only be started when: The blades are disengaged. The motion control levers must be in the locked position.
Check that the engine responds to throttle increases and that a good engine speed is attained at full throttle. If doubts arise, contact the Husqvarna service workshop. If adjustments are necessary, they can be made as follows for the cable: Loosen the clamping screw for the cable’s outer casing.
Kawasaki Engine Air Filter If the engine seems weak or runs unevenly, the air filter may be clogged. If run with a dirty air filter, the spark plugs can become fouled and disrupt operation. For this reason, it is important to replace the air filter regularly (see the heading Maintenance Schedule for the proper service interval).
Kohler Engine Air Filter If the engine seems to lack power or runs rough the reason may be that the air filter is clogged. It is therefore important to service the air filter at regular intervals (see “Maintenance Schedule” on page 35 for correct service interval).
Replacing the Fuel Filter Replace the line-mounted fuel filter every 100 hours (once per season) or more regularly if it is clogged. Replace the filter as follows: Move the hose clamps away from the filter. Use flat-nosed pliers. Pull the filter loose from the hose ends. Push the new filter into the hose ends.
Checking the Parking Brake Visually check that no damage is found on the thumb latches. Perform a test drive and check that there is a sufficent braking action. To adjust the brake, contact the service workshop if you are uncertain. Set the thumb latches in the neutral locked position.
Checking the Blades In order to attain the best mowing effect, it is important that the blades are well sharpened and not damaged. Bent or cracked blades or blades with large nicks must be replaced. Check the blade mounts. IMPORTANT INFORMATION The replacement or sharpening of blades should be carried out by an authorized service workshop.
Cleaning and Washing Regular cleaning and washing, especially under the mower deck, will increase the machine’s lifespan. Make it a habit to clean the machine directly after use, before the dirt sticks. Do not spray high pressure water directly on the top of the deck. Caster Wheels Check every 200 hours.
• Install and tighten blade bolt securely. Tightening torque 90 ft/lb (122 Nm). IMPORTANT INFORMATION Special blade bolt is heat treated. Replace with a Husqvarna bolt if required. Do NOT use lower grade hardware than specified. English- MAINTENANCE Blade Center hole...

5. Engine oil Kawasaki Engine Changing the Engine Oil The engine oil should be changed for the first time after 8 hours of operation. Thereafter, it should be changed every 100 hours. WARNING! Engine oil can be very hot if it is drained directly after stopping the engine.
Page 53
LUBRICATION The oil level should lie between the markings on the dipstick. If the level is approaching the ”ADD” mark, fill the oil to the ”FULL” mark on the dipstick. Never fill above the ”FULL” mark. The oil is filled through the hole for the dipstick.
Page 54
Kohler Engine Changing the Engine Oil Change oil after every 100 hours of operation (more frequently under severe conditions). Refill with service class SG, SH, SJ or higher oil as specified in the Viscosity Grades table on page 54. Change the oil while the engine is still warm. The oil will flow more freely and carry away more impurities.
Page 55
Checking the Oil Level The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check oil before each use as follows: Make sure the engine is stopped, level, and is cool so the oil has had time to drain into the oil pan.
Page 56
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...
