Operating Your Lawn Mower 

Once the engine has started, squeeze the blade 
control handle against the upper handle to run the 
lawn mower. 

Do not operate the mower without the mulching 
cover, the grass catcher bag, or the discharge 
chute properly installed.

Be sure that the lawn is clear of stones, sticks, wire, 
or other objects which could damage lawn mower 
or engine. Such objects could be accidently thrown 
by the mower in any direction and cause serious 
personal injury to the operator and others.

For best resultsdo not cut wet grass because it 
tends to stick to the underside of the mower, 
preventing proper discharge of grass clippings, 
poor mulching conditions, and could cause you to 
slip and fall. New grass, thick grass, or wet grass 
may require a narrower cut.

For a healthy lawn, always cut off one-third or less 
of the total length of the grass. Lawn should be 
trimmed in fall as long as there is growth.

Bagging Grass Clippings

You can use the grass catcher bag to collect clippings 
while you are operating the mower. 

Attach the grass catcher following instructions on 
page 8 of this manual. Grass clippings will 
automatically collect in the bag as you run mower. 

Operate mower till the grass bag is full. 

Stop the engine completely by releasing the control 
handle. Make sure that the unit has come to a 
complete stop. 

Lift discharge door and pull grass bag up and away 
from the mower to dispose of the grass clippings.

Using the Mulcher

For effective mulching, do not cut wet grass 
because it tends to stick to the underside of the 
deck, preventing proper mulching of grass 
clippings. New or thick grass may require a 
narrower cut. The ground speed should be 
adjusted to the condition of the lawn. If mowing has 
been delayed and the grass has been allowed to 
grow in excess of 4", mulching is not 
recommended. Mow using the grass bag (if so 
equipped) to reduce the grass height to 3-1/4" 
maximum before mulching.

Adjusting Cutting Height

Refer to height adjustments section of this manual on 
page 14 for instruction on how to adjust the cutting 
height and the handle height. 

For best results in mowing, keep the cutting height 
position high until you have determined which 
cutting height is preferred. 

WARNING: 

If you strike a foreign object, 

stop the engine. Remove spark plug wire from 
spark plug, thoroughly inspect the mower for 
any damage. Repair the damage before 
restarting and operating the mower. Extensive 
vibration of the mower during operation is an 
indication of damage.
