SAFETYThis operator manual describes the Husqvarna Zero Turn Rider. The rider is tted with a four- stroke overhead valve engine. Power transmission from the engine is made via belt-driven hydraulic pumps. Using the left and right steering controls, the ow is regulated and thereby the direction and speed.

CONTROLSSteering Control Levers The machine’s speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or back about a neutral position. There is a neutral / parking brake position which sets the parking brake when the steering controls are moved out. When both controls are in the neutral position (N), the machine stands still. By equally moving both controls forward or backward, the machine moves in a straight line forward or backward. Park Brake Forward Neutral Reverse For example, to turn right while moving forward, move the right control towards the neutral position. The rotation of the right wheel is reduced and the machine turns to the right. Zero turn can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position. The rotation direction when zero turning is determined by which steering control is moved backward behind the neutral position. If the left steering control is pulled backward, the machine turns to the left. Use more care when using this maneuver. If the steering controls are in uneven positions when standing still or do not t in the slots for moving the controls out, they can be adjusted. IMPORTANT INFORMATION The machine must stand still when engaging the park brake. Always engage the park brake before dismounting. Release the park brake before moving the mower. WARNING! The machine can turn very fast if one steering control is moved much further forward than the other. Throttle Control The throttle controls the engine speed and the rate of rotation of the blades, assuming the blade switch is pulled out. The control is moved forward or back to increase or decrease the engine speed. To prevent the risk of fouling the spark plugs, do not idle the engine for long periods. USE FULL THROTTLE WHEN MOWING, for best mower performance and battery charging. Ignition Switch The ignition switch is used to start and stop the engine. On models with headlights, turn the key clockwise to ACCESSORY for headlight use.

CONTROLSFuses Fuses are on the right hand side of the machine and are accessed by tilting the seat forward. Fuses are at pin fuses type as used in automobiles. The 20 A is the primary fuse. The

7.5 A is for the mower deck coupling.

Fuel Shut O󰀨 Valve Blade Switch To engage the mower deck, pull the knob out; mower blades are disengaged when the knob is pressed down. Service Meter Seat Adjustment Lever (Applies to Z400X only) Choke Control The choke control is used for cold starts to give the engine a richer fuel mixture. For cold starts, pull the control up. The service meter displays the total number of hours the engine has run and shows when the engine and mower need servicing. After every 50 hours of operation, an oil can icon will appear and stay on for two hours, before an automatic reset occurs. To manually reset the meter, turn the key o󰀨 and on ve times at one second intervals. To service the engine and mower, see the Service Journal of this manual. Note: The service meter operates (clocks hours) only when the engine is running. Be sure to turn the key o when the unit is not in use, to prevent meter hours from accumulating. The seat can be adjusted lengthways. The lever under the front edge of the seat is moved to the left (as seen by the driver in the seat), to adjust the seat backward or forward. IMPORTANT INFORMATION Seat must not be adjusted while unit is in motion. The fuel shut o󰀨 valve is just forward of the rear fuel tank mount bracket. The valve is o󰀨 when the handle tab is turned perpendicular to the fuel line.

CONTROLSCutting Height Pedal The desired cutting height is set with the height pin. The cutting height pedal releases the deck lift to place the deck at the selected height. For transport, push the lift pedal fully forward until the deck lift latches in the transport (highest) position. Tracking If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure for the rear tires is 15 psi (1 bar).

1. Tracking adjustments are made using the

2. For preliminary tracking adjustment, move

unit to an open, unobstructed area such as an empty parking lot or open eld.

3. Turn the tracking bolts in as far as possible.

4. Back the tracking bolts out 4 full turns. Any

more than four turns could damage the unit.

5. Test operate unit by driving it at full throttle

and the full forward position on both motion control levers. Gradually turn in the tracking bolt on the right hand side until the unit noticeably starts drifting right.

6. Drive forward at full throttle with both motion

control levers in the full forward position. Gradually turn in the tracking bolt (left side) until unit tracks straight. Hydro Release Levers Transmission bypass levers must be engaged when pushing or pulling the machine. Transmissions are put into bypass mode by rotating the levers to the horizontal position. The bypass levers are located at the front of both transmissions. See Manual Transport in the Operation section. IMPORTANT INFORMATION Always raise the deck to the highest position for transport. Fuel Tank Read the safety instructions before refueling. The capacity for the tank is ve gallons. Regularly check the gas cap gasket for damage and keep the cap correctly tightened. The engine will run on a minimum of 87-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. See Technical Data concerning ethanol fuel. Methanol fuel is not allowed. Do not use E85 alcohol based fuel. Damage to the engine and components can occur. When operating in temperatures below 32°F, use fresh, clean winter grade gasoline to ensure good cold weather starting.

CONTROLSWARNING! Gasoline is very ammable. Observe caution and ll the tank outdoors (see the safety section). IMPORTANT INFORMATION Experience shows 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 must 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 for more information. Do not use engine or carburetor cleaners in the fuel tank or permanent damage can occur. WARNING! Fill to the bottom of the ller neck. Do not add too much gasoline. Wipe o󰀨 spilled oil or fuel. Do not keep, spill or use gasoline near an open ame. WARNING! The engine and the exhaust system become very hot during operation. There is a risk for burns if touched. Let engine and exhaust system to cool before refueling.

CONTROLSRead the Safety section and following pages, if you are unfamiliar with the machine. Training Due to unique steering capabilities, zero turn mowers are far more maneuverable than typical riding mowers. Review this section fully before trying to move the mower under its own power. When rst operating the mower or until becoming comfortable with controls, use a reduced throttle speed and reduced ground speed. DO NOT move control levers to the furthest forward or reverse positions during initial operation. First time users must become familiar with the mower’s movement on a hard surface, such as concrete or asphalt BEFORE trying to operate on turf. Until the operator becomes comfortable with the mower controls and zero turn, overly aggressive maneuvers can damage turf. Steering To move forward and rearward The direction and speed of the mower’s movements are e󰀨ected by the movement of the control lever(s) on each side of mower. The left lever controls the left wheel. The right lever controls the right wheel. First time users must push the mower (see Moving Machine By Hand in the Operation section) to an open, at area without other persons, vehicles or obstacles nearby. To move the unit under its own power, the operator must sit in the seat and start the engine (see Before Starting in the Operation section). Adjust the engine speed to idle, do not engage the blades at this time. Pull control levers inward. As long as the control levers have not been moved forward or to the rear, the mower will not move. Slowly move the two control levers forward slightly. This will let the mower start moving forward in a straight line. Pull the control levers back to the neutral position and stop the mower from moving. Pull back slightly on control levers, allowing the mower to move to the rear. Push the control levers forward to the neutral position to stop the mower from moving. To turn to the right While moving in a forward direction, pull the right lever back towards the neutral position while maintaining the position of the left lever, this will slow the rotation of the right wheel and cause the machine to turn in that direction. To turn to the left While moving in a forward direction pull the left lever back towards the neutral position while maintaining the position of the right lever, this will slow the rotation of the left wheel and cause the machine to turn in that direction. To zero turn While moving in a forward direction, rst pull the two control levers back until the mower stops or slows dramatically. Then by alternating one lever slightly to the forward position and the other in the reverse position, complete the turn. Roll Bar Operate the unit with the roll bar in the raised and locked position and use the seat belt. There is no rollover protection when the roll bar is down. If it is necessary to lower roll bar, do not wear the seat belt. Raise the roll bar as soon as clearance permits. WARNING! The seat belt must be used when the roll bar is in upright position. WARNING! Make sure the work area is free of stones and other objects that could be thrown by the rotating blades. Before Starting

4. Raise the mower deck by pressing the foot

pedals forward to the transport position.

5. Engage the park brake by moving the control

levers outward into the park brake position. If the engine has been worked hard, let it to idle at least 60 seconds and get to a normal operating temperature before stopping. To prevent fouling the spark plugs, avoid idling the engine for longer periods.

6. Turn the ignition key to the stop position and

remove the key. Always remove the key when leaving the mower to prevent unauthorized use. IMPORTANT INFORMATION Leaving the ignition switch in a position than OFF will cause the battery to be discharged. Operating on Hills Read the Safety Instructions Driving on Slopes in the Safety section.

• Use the slowest speed possible before starting up or down hills.

OPERATION• Avoid stopping or changing speed on hills.

• If stopping is necessary, pull drive levers into the neutral position and push outward. Engage the park brake.

• To restart movement, release the park brake.

• Pull the control levers back to the center of the mower and push forward to regain forward motion.

• Make all turns slowly. WARNING! Do not drive the rider on terrain that slopes more than 10 degrees. Mow slopes up and down, never side to side. Avoid sudden directional changes. Mowing Tips

• Observe and ag rocks and other xed objects to avoid collisions.

• Begin with a high cutting height and reduce it until the desired mowing result is attained. Cut the average lawn to 6.35 cm during the cool season and over 7.62 cm during the hot months. For healthier and better looking lawns, mow frequently after moderate growth.

• For best cutting performance, mow grass over

15.24 cm in height twice. Make the rst cut

relatively high; the second to the desired height.

• The mowing result will be best with a high engine speed (the blades turn rapidly) and low speed (the rider moves slowly). If the grass is not too long and dense, the driving speed can be increased without negatively a󰀨ecting the mowing result.

• The nest lawns are obtained by mowing frequently. The lawn becomes more even and the grass clippings more evenly distributed over the mown area. The total time taken is not increased as a higher operating speed can be used without poor mowing results.

• When mowing large areas, start by turning to the right so that clippings will discharge away from shrubs, fences, driveways, etc. After one or two rounds, mow in the opposite direction making left hand turns until nished.

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

• Hose the mower deck underside with water after each use. When cleaning, the mower deck shall be raised into the transport position. Make sure the mower is cooled and the engine is o󰀨.

• Use compressed air to clean top surface of the deck. Avoid ooding water on top surface, engine and electrical components.

• When the mulching kit is used, it is important that the mowing interval is frequent. Moving Machine By Hand When pushing or pulling the mower, engage the bypass levers. The bypass levers are located at the front of each transmission.

1. Lower the deck if needed.

2. Move the steering controls inward out of the

park brake position.

4. Rotate each bypass lever to the horizontal

6. Push the mower using the sturdy feature of

the mower's structure. Do not push the mower with the control levers.

7. To reengage the transmission, rotate the

bypass levers to the vertical position.

OPERATIONLoad the machine into truck or trailer by driving up ramps in low gear. DO NOT LIFT! The machine is not intended to be lifted by hand. WARNING! Once the bypasses are engaged, and the steering controls are moved in to release the parking brake, the unit is free to roll and potentially injure someone. WARNING! Use more care when loading the machine into a truck or trailer using ramps. There is the possibility of dangerous injury or death if the machine falls o󰀨 the ramps. WARNING!

Safety System The machine has a safety system that prevents starting or driving under the following conditions. The engine can only be started when:

• the mower deck is disengaged.

• the steering controls are in the outer, locked neutral / parking brake position. IMPORTANT INFORMATION To be able to drive, the driver must be seated and move both steering levers in toward each other at the same time, otherwise the engine will stop. Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met. Change the conditions and try again. If the machine starts when one of these conditions is not met, turn the machine o󰀨 and repair the safety system before using the machine again. Make sure the engine stops when the park brake is released and the operator leaves the seated position. Check that the engine stops if the mower blades are engaged and the driver temporarily moves o󰀨 the driver’s seat. Park Brake and Steering Visually check that no damage is found on the lever, links, or switches belonging to the park brake. Do a standstill test and check that there is su󰀩cient braking. For park brake adjustments, contact the Husqvarna service workshop. WARNING! Faulty adjustment will result in reduced braking and can cause an accident. Tire Pressures All tires must be at 15 psi / 103 kPa / 1 bar. IMPORTANT INFORMATION DO NOT add a tire liner or foam ll material to the tires. Excessive loads created by foam lled tires will cause premature failures. Only use tires specied by Husqvarna.

MAINTENANCEPump Belt The transmissions drive belt tension is adjustable. The tension spring should be compressed to a length between 1.38 and 1.50 inches.

a spring length between 1.38 and 1.50 inches.

Cutting Blades CAUTION! Blades are sharp. Protect your hands with gloves and/or wrap blades with a heavy cloth when handling. The sharpening of blades must be carried out by an authorized service workshop. For the best mowing e󰀨ect, it is important that the blades are well sharpened and not damaged. Replace blades that have been bent or cracked when hitting obstacles. Let the service workshop decide whether a blade with large nicks can be repaired/ground or must be replaced. Balance the blades after sharpening. Check the blade mounts. Blade Replacement

1. Remove blade bolt by turning it counter

2. Install new or re-sharpened blade with

stamped GRASS SIDE facing toward the ground/grass (down) or THIS SIDE UP facing the deck and cutter housing.

3. Install and tighten the blade bolt correctly.

4. Torque the blade bolt to 45-55 ft/lb (61-75

Nm). IMPORTANT INFORMATION The special blade bolt is heat treated. Replace it with a Husqvarna bolt if necessary. Do not a use lower grade hardware than specied.

MAINTENANCEAdjusting the Mower Deck Leveling Deck Adjust the deck while the mower is on a level surface. Make sure the tires are inated to the correct pressure. See Tire Pressures in Maintenance section. If tires are under or over inated, the deck cannot be correctly adjusted. Faulty mower deck adjustments will cause an uneven mowing result. Four slots control the height and pitch of the mower deck. Adjust the deck slightly higher in the rear. NOTE: To ensure precision in the leveling procedure, the mower deck drive belt must be installed before leveling the deck.

1. Wear heavy gloves. Turn each outer blade tip

to align with the deck side to side.

2. Measure from the oor surface up to the

bottom of the blade tip on the discharge side of the mower deck. Record this measurement. Move to the opposite side; check that measurement is the same. If adjustment is required, loosen the locknut on the top of the rear links and adjust until both side to side measurements are equal. Retain measurement.

3. Turn both outer blades to align with the deck

front-to-rear. Reposition the front mounting bolts up or down until the rear blade tips are positioned 1/8" to 3/8" higher in the rear than the front blade tips.

4. Conrm measurements once again. The

blade tip height must be equal side-to-side. In the rear, blade tips must be 1/8" to 3/8" higher than the front measurement. In the front, blade tips must be equal from side-to-side. NOTE: This will place the mower deck in a standard measurement position. Depending on the type of grass being mowed or environmental conditions, more adjustments can be necessary to get the desired cut. Powertrain Regular external maintenance of the powertrain should include the following:

1. Check each transmission oil level. When the

engine is cold, the oil level should touch the bottom of each transmission oil dipstick.

2. Examine the vehicle drive belt, idler pulley(s),

and idler spring(s). Ensure that no belt slippage can occur. Slippage can cause low input speed to the transmissions.

3. Examine each transmission cooling fan

for broken or bent blades. Remove any obstructions such as grass clippings, leaves or dirt.

4. Examine the park brake and vehicle linkage to

make sure they work correctly.

5. Examine the vehicle control linkage to the

directional control arm on the transmissions. Also, make sure the control arm is correctly fastened to the trunnion arm of the transmissions.

6. Examine the bypass levers on the transmissions

and make sure they rotate freely. IMPORTANT INFORMATION Any servicing dealer attempting a warranty repair must have prior approval before conducting maintenance of a Parker® product, unless the servicing dealer is a current Authorized Parker™ Service Center.

MAINTENANCECleaning Regular cleaning, especially under the mower deck, will increase the machine’s life-span. Clean the machine directly after use (after it is cooled), before the debris sticks. Do not spray water on the top of the mower deck. Use compressed air to clean the top side of the mower deck. Do not use a high pressure washer or steam cleaner. Avoid spraying engine and electrical components with water. Clean the underside of the deck with normal water pressure. Do not rinse hot surfaces with cold water. Let unit cool before washing. CAUTION! Always wear eye protection when cleaning and washing. Hardware Check daily. Examine the machine for loose or missing hardware. Caster Wheels Check every 200 hours. Check that wheels turn freely. Foam lled tires or solid tires will void the warranty. To replace, remove the nut and caster bolt. Pull the wheel out of the yoke and take care with the spacer. Install in reverse order. Tighten the caster bolt and torque to 45 ft/lb (61 Nm). NOTE: Tire must turn freely but axle spacers must not. If wheels do not turn freely take the unit to the dealer for service. Anti-scalp Rollers Anti-scalp rollers are correctly adjusted when they are slightly o󰀨 of the ground when the deck is at the desired cutting height. Anti-scalp rollers keep the deck in the correct position to prevent scalping in most terrain conditions. Do not adjust the rollers to support the deck. The rollers must be approximately 1/4" (6.5 mm) from ground. IMPORTANT INFORMATION Adjust anti-scalp rollers with the mower on a at level surface. To avoid deck damage, the anti-scalp rollers must not be adjusted to support the deck.

MAINTENANCEGeneral Remove the ignition key to prevent unintentional movements during lubrication. When lubricating with an oil can, it must be lled with engine oil. When lubricating with grease, unless otherwise stated, use high grade molybdenum disulde grease. For daily use, the machine must be lubricated twice weekly. Wipe away excess grease after lubrication. It is important to avoid getting lubricant on the belts or the drive surfaces on the belt pulleys. If this happens, clean them with spirits. If the belt continues to slip after cleaning, it must be replaced. Gasoline or other petroleum products must not be used to clean belts. Qualied Hydraulic Oils If Parker™ HT-1000 oil is used continually, the oil and lters must be changed every 750 hours. If Castrol™ Syntec 5W-50, Amsoil AW ISO 68, or Shell™ TTF-SB oils are used, the oil and lters must be changed every 500 hours after the initial 750 hour oil and lter change. Lubrication Schedule If a premium grade synthetic engine oil with a minimum viscosity grade of 15W40 is used, then the oil and lters must be changed every 250 hours after the initial 750 hour oil and lter change. IMPORTANT INFORMATION Use minimal lubrication and remove excess lubricant so that is does not come into contact with belts or belt pulley drive surfaces. WARNING! Escaping hydraulic oil under pressure can have su󰀩cient force to penetrate the skin, causing serious injury. If injured by escaping uid, see a doctor at once. Serious infection or reaction can develop if proper medical treatment is not administered immediately. 12/12 Every year 1/52 Every Week 1/365 Every day Lubricate with grease gun Filter change Oil change Level check

Initial hydraulic oil and lter change at 100 hrs, every 400 hrs thereafter Change engine oil every 50 hours

LUBRICATIONWheel and Deck Zerks Use only good quality bearing grease. Grease from well-known brand names (petrochemical companies, etc.) usually maintains a good quality. Front Wheel Mount Lubricate 3-4 strokes with a grease gun on each set of wheel mounts. Front Wheel Bearings Lubricate 3-4 strokes with a grease gun on each set of wheel bearings. Deck Spindles Lower the cutting deck completely. If a grease gun without rubber hose is used, the foot plate must be removed to access the center spindle. Lubricate with a grease gun, 2-3 strokes per spindle. Engine oil change NOTE: Change the engine oil when the engine is warm. Refer to the engine owner’s manual for the correct replacement oil and lter change recommendations. WARNING! The engine drain plug is near to the mu󰀪er. To prevent burns, the engine should be shut o󰀨 and allowed to cool slightly so the engine is still warm but the adjacent surfaces and oil are not.

1. Park on a level surface. Engage park brake.

2. Clean the dirt and debris from the area around

3. Remove the cap/dipstick.

4. Find the drain hose at the right rear of the

engine. Place a su󰀩ciently sized container under the end of the drain hose and remove the oil drain plug.

6. Replace and tighten the drain hose plug.

7. Fill the engine with new oil to the bottom of

the ll tube threads. Check the level with the dipstick.

8. Replace and tighten the oil ll cap when the

9. To discard the used oil, refer to local disposal

10. Refer to the Service Journal for oil checking

and changing intervals and change recommendations.

LUBRICATIONOil and Filters Change The hydraulic oil and lters must be replaced every 250 to 750 hours or once per year, depending on the type of oil used. See Qualied Hydraulic Oils in the Lubrication section for a list of approved oils or refer to the transmission manufacturers service manual. Due to the risk of impurities entering the system, all transmission work should be performed by an authorized service workshop. The following procedure is performed with the transmissions installed in the mower and the mower on level ground. Apply the pump release valve for each transmission and set the park brake.

1. Thoroughly clean the unit free of grass and

other debris. Clean any loose debris from around the perimeter of the lter.

2. Remove breather / dipstick.

3. Place an oil drain pan (12" or more diameter

and 8 qt. capacity is optimal) beneath the oil lter.

4. Using a socket and ratchet, remove lter plug

and O-ring assembly.

5. Using a strong magnet or pair of needle nose

pliers, remove the oil lter.

6. Install the new lter.

7. Install lter plug and O-ring assembly. Torque

lter plug to 115–135 in/lbs.

8. Repeat steps on the opposite side.

9. Drain old oil lters of all free owing oil prior

to disposal. Place used oil in appropriate containers and dispose of it in accordance with laws in your area.

10. Fill transmission with Paker HT-1000

transmission oil or other approved hydraulic uid.

11. The cold uid level should touch the bottom of

the breather / dipstick.

12. Install breather / dipstick and torque to 18–30

in./lbs. Transmission Purging Purge procedures must be implemented if the hydrostatic system has been opened for maintenance or when more oil has been added to the system. Due to the e󰀨ects air has on e󰀩ciency in hydrostatic drive applications, it is critical to purge the system. Resulting symptoms of air in hydrostatic systems may be:

• Lack of power or drive after short term operation.

• High operation temperature and excessive expansion of oil.

• Shortened component life. Before starting, make sure the oil tank is at the proper oil level. If not, ll to the specications outlined above. Perform the procedure rst with the vehicle drive wheels o󰀨 the ground, then repeated under normal operating conditions. See Moving Machine By Hand in the Operation section for bypass linkage adjustments.

1. Disengage the brake if activated.

2. With the bypass linkage open and the

engine running at fast idle, slowly move the directional control in both forward and reverse directions (5 or 6 times). As air is purged from the unit, the oil level will drop.

3. With the bypass linkage closed and the

engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times). Check the oil level and add oil as required after stopping the engine.

4. It may be necessary to repeat Steps 2 and 3

until all the air is completely purged from the system. When the hydraulic drive operates at normal noise levels and moves smoothly forward and reverse at normal speeds, the hydraulic drive is considered purged.

5. After the vehicle has been used two times, the

oil level must be checked while the oil is cold and adjusted accordingly.

TROUBLESHOOTING Problem / CauseWinter Storage The machine must be readied for storage at the end of the mowing season, or if it will not be in use for more than thirty days. Fuel allowed to stand for long periods of time (thirty days or more) can leave sticky residues that can plug the carburetor and disrupt engine function. Fuel stabilizers are an permitted 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 specied by the manufacturer of the stabilizer. Run the engine for at least ten minutes after adding the stabilizer so that it reaches the carburetor. Do not empty the fuel tank and the carburetor if a stabilizer has been added. WARNING! Do not 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 dryer, 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 store far away from open ame or sources of ignition. Do not use gasoline for cleaning. Use a degreaser and warm water. To ready the machine for storage:

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 underside of the mower deck to avoid corrosion.

2. Inspect the machine for worn or damaged

parts and tighten 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 let it run until the carburetor is drained of fuel or the stabilizer has reached the carburetor.

5. Remove the spark plug and pour about a

tablespoon of engine oil into the cylinder. Turn over the engine so that the oil is evenly distributed and then ret the spark plug.

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

7. Remove the battery. Clean, charge, and store

the battery in a cool place, but protect it from direct cold.

8. 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 the machine performs its best the following season.
