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 recom-
mend 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 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.
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
shutdown 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.
NOTE
ALL MOWERS SHOULD BE TILTED WITH
THE CARBURETOR SIDE UP
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.
BLADES
If blades are in good condition, sharpen at an
angle of 22 to 28 degrees about 2-1/2" in from
the tips.
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 follow-
ing:
1. Ground speed - too fast for proper cutting.
Shift to a lower gear.
2. Engine speed - 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 rela-
tionship with rear axle. Adjust as necessary.
6. Belt slippage - causing bad cutting pattern or
uneven cut. Adjust belt tension
7. Tire pressure - uneven tire pressure can
cause an uneven cut from one side of the deck
to the other. Equalize tire pressure.
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.
