REPLACEMENT PARTS
To retain the quality of your mower, use genuine HUSQVARNA replacement parts only. Contact your local HUSQVARNA dealer for parts and service assistance. For the correct part or information for your particular mower, always mention model and serial number. We recommend returning your mower to an authorized HUSQVARNA dealer on a yearly basis for inspection and addition of any new devices which might upgrade the performance and safety of your mower. For engine parts and service, look in the yellow pages for the engine manufacturer's dealers under the heading engines - gasoline.
WARNING
BEFORE PERFORMING SERVICE ON THE MOWER TURN ENGINE OFF, CLOSE THE FUEL VALVE, AND DISCONNECT THE BATTERY AND ALLOW ENGINE TO COOL. DISCONNECT THE SPARK PLUG WIRE. IF THE MOWER IS TO BE RAISED OR TILTED, MAKE SURE TO SECURE THE MOWER IN PLACE.
NOTE
ALL MOWERS SHOULD BE TILTED WITH
THE CARBURETOR SIDE UP
MODULE SYSTEM
The interlock modules function is to prevent the engine from starting if the blade and/or traction systems are engaged. It also causes engine shut- down if the operator falls from, or attempts to leave the operator position while the blades or traction drives are engaged. After the engine starts, the operator must hold either the left or right O.P. lever down before engaging the blades or shifting the transmission into gear. If neither O.P. lever is held the engine will stop.
INTERLOCK SAFETY SYSTEM
Check the function of the safety electrical system on a regular basis.
1.Engine must kill if blades are engaged without O.P. levers held down.
2.Engine must kill if transmission is taken out of neutral without holding down O.P. levers.
3.Engine must not start unless blades are off and transmission is in the neutral position.
4.Do not operate the mower if the interlock safety system allows operating or starting in any unsafe condition.
CAUTION
DO NOT BYPASS THE INTERLOCK SWITCHES THEY ARE FOR YOUR PROTECTION! CHECK THE OPERATOR PRESENCE SYSTEM DAILY ALONG WITH THE TRACTION DRIVE SWITCHES AND BLADE SWITCH FOR PROPER OPERATION. REPAIR IMMEDIATELY IF A
PROBLEM IN THE SYSTEM IS FOUND. DO NOT OPERATE MOWER IN A DAMAGED CONDITION.
NEUTRAL LOCK THUMB LATCH
The point between neutral and drive on the slot of the thumb latches should be checked every 50 hours. If the point is rounded it should be replaced.
See figure 7 on page 10.
BLADES

NOTE
AFTER SHARPENING, CHECK BLADES FOR PROPER BALANCE, IF NEEDED CORRECT BAL- ANCE TO PREVENT EXCESSIVE VIBRATION
CUTTING DECK SERVICE
If mower is cutting improperly, check the following:
1.Ground speed - too fast for proper cutting. Shift to a lower gear.
2.Engine speed - too low for proper cutting. Increase engine speed.
3.Cutting height - too low for ground/grass conditions. Adjust to higher cut.
4.Blade spacers - not positioned properly on all blade shafts. Visually inspect and replace or adjust as necessary.
5.Front casters - spacers not in correct relationship with rear axle. Adjust as necessary.
6.Belt slippage - causing bad cutting pattern or uneven cut. Adjust belt tension
