Maintenance
Turn off engine and detach spark plug wire.
Engine must be cool before performing any maintenance.
1. Make sure unit is on a level surface, stop engine, and wait
for all moving parts to stop. Check with engine cold.
2. Clean area around dipstick. Remove dipstick and wipe oil
off. Reinsert the dipstick. Do not screw into place. Remove
the dipstick and read the oil level.
3. If the oil level is low, add oil to bring the oil level up to
the FULL mark on the dipstick. Use oil as specified in the
Engine Owner’s Manual. Do not overfill.
DO NOT operate the engine with oil level below the LOW
or ADD mark on the dipstick or over the FULL mark.
4. Clean engine cooling system daily or more often in dry
conditions. Clean all debris from rotating engine air intake
screen and from around engine shrouding.
5. Clean grass build-up from under deck. Raise deck to the
highest position. Lift the front of unit and support unit
using jack stands or equivalent support. Clean out any grass
build-up from underside of deck and in discharge chute.
6. Check mower blades by lifting deck and secure in raised
position with jack stands or equivalent support. Inspect
blades and sharpen or replace as required. Re-install the
blades by placing a block of wood between the front or rear
baffles and the blade (see Figure 8), then torque the blade
bolts to 115-120ft-lbs. Be sure the spring disk washer cone
is installed toward the bolt head.
A loose or weakened blade bolt could allow a blade rotating
at a high speed to come out from under the deck, causing
serious injury or property damage.
Do not lubricate the threads of connecting bolts.
