weather. In warmer weather, over primming
may cause flooding and engine will not start.
If you do flood engine, wait a few minutes be-
fore attempting to start and DO NOT repeat
primming steps.

MOWING TIPS

CAUTION: Do not use de-thatcher blade at-
tachments on your mower. Such attachments
are hazardous, will damage your mower and
could void your warranty.
• For most cutting conditions and better bag-
ging performance, the engine speed should be
set in the FAST position.
• Under certain conditions, such as when mow-
ing very tall grass, raise the mower height on
the first cut to reduce pushing effort, to avoid
overheating the engine, and to avoid leaving
clumps of grass clippings. Make the second cut
to the desired height.
• For extremely heavy cutting, reduce the
width of cut.
• For side discharge lawn mowers, cut in a
counterclockwise direction, starting at the out-
side of the area to be cut, in order to spread
grass clippings more evenly and to put less load
on the engine. To keep clippings off of walk-
ways, flower beds, etc., make the first cuts in a
clock-wise direction.

ADJUSTMENTS

HEIGHT CUT CONTROL
Stop the motor before making any adjustment
at the cutting height; the height adjustment
regulates every wheel independently.
To make the adjustments simply move the
wheel lever to the desired position

BLADE CARE

For best results, mower blade must be kept
sharp. Replace a bent or damaged blade.

CAUTION: Use only a replacement blade ap-
proved by the manufacturer of your mower.
Using a blade not approved by the manufac-
turer of your mower is hazardous, could dam-
age your mower and void your warranty.
TO REMOVE BLADE
1. Disconnect spark plug wire from spark plug
and place wire where it cannot come in contact
with plug.
2. Turn lawn mower on its side. Make sure air
filter and carburetor are up.
3. Use a wood block between blade and mower
housing to prevent blade from turning when
removing blade bolt.
NOTE: Protect your hands with gloves and/or
wrap blade with heavy cloth.
4. Remove blade bolt by turning counter-clock-
wise.
5. Remove blade and attaching hardware (bolt,
lock washer and hardened washer).
NOTE: Remove the blade adapter and check
the key inside hub of blade adapter. The key
must be in good condition to work properly.
Replace adapter if damaged.
TO REPLACE BLADE
1. Position the blade adapter on the engine
crankshaft. Be sure key in adapter and crank-
shaft keyway are aligned.
2. Position blade on the blade adapter aligning
the two (2) holes in the blade with the raised
lugs on the adapter.
3. Be sure the trailing edge of blade (opposite
sharp edge) is up toward the engine.
4. Install the blade bolt with the lock washer
and hardened washer into blade adapter and
crankshaft.
5. Use block of wood between blade and lawn
mower housing and tighten the blade bolt,
turning clockwise. The recommended tighten-
ing torque is 35-40 ft. lbs.
IMPORTANT: Blade bolt is heat treated. If bolt
needs replacing, replace only with approved
bolt shown in the Repair Parts section of this
manual.
TO SHARPEN BLADE
NOTE: We do not recommend sharpening blade
but if you do, be sure the blade is balanced. An
unbalanced blade will cause eventual damage
to lawn mower or engine.
• The blade can be sharpened with afile or on
a grinding wheel. Do not attempt to sharpen
while on the mower.
