Safety Interlock System; Starting And Operation - Husqvarna WH3614A Operator's Manual

OPERATING INSTRUCTIONS

STARTING AND OPERATION:

1. Making sure the blades are disengaged, ground speed lever in neutral, the thumb latches
locked, and the fuel valve on.
2. Adjust throttle to choke (if needed) turn key to on position.
3. Pull start the engine. Once the engine is running adjust the throttle.
4. Holding down at least one of the operator presence levers, engage blades and set RPM to
maximum, but not choked. NOTE: Be sure all persons are clear of area before engaging the
blades. To prolong spindle bearing and belt life engage and disengage blades at approximately
1\2 throttle.
5. Set the ground speed lever to the desired position.
6. Release the thumb latches at the same time.
MAINTENANCE
1. Engine oil level: Check daily with engine cold and on a flat surface. Remove the dipstick and
wipe clean. Reinsert the dipstick all the way, but do not screw down. Remove the dipstick and
check oil level. If oil level is low add oil. Use engine manufacturers specs for type of oil.
2. Pump drive belt: Stop engine and remove key. Check the tension on the belt.
3. Mower blades: Stop engine and remove key. Inspect blades and sharpen or replace as needed.
Check daily or more often if needed. The machine requires more power with dull blades and
gives a poor cut. If blades get bent, replace them. Blades shouldn't have any notches from
hitting objects. The air foil on top of the blade should be sufficient to raise the grass for cutting. If
blades are in good condition, sharpen at an angle of 22 to 28 degrees about 2-1/2 inches in from
the tips. Note: After sharpening, check blades for proper balance, if needed correct balance to
prevent excessive vibration.
4. Safety interlock system: Check daily and never operate the mower if this system is not func-
tioning properly.
