Disconnect spark plug wire and move away from 
spark plug to prevent accidental starting. 

Using Your Lawn Mower

For best results, do not cut wet grass. It may stick to 
the underside of the mower, preventing proper 
discharge of grass clippings, and could cause you 
to slip and fall. New grass or thick grass may 
require a narrower cut.

For a healthy lawn, always cut off one-third or less 
of the total length of the grass. 

IMPORTANT: 

Move the shift lever only when the engine 

is running. Changing the shift lever setting with the 
engine off can cause damage to the mower. 

Mulching

IMPORTANT: 

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 effective mulching, do not cut wet grass. New or 
thick grass may require a narrower cut. If the grass has 
grown in excess of 4”, mulching is not recommended. 

Mow using the side discharge to reduce the grass 
height to 3.25” maximum before mulching.

Bagging Grass Clippings

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

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

Operate the mower till the grass bag is full. 

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

While holding the grass bag by both the rear handle 
and the lower handle, lift the grass bag straight up 
off the adapter. The chute door will move the rope 
out of the way of the bag.

Continue to hold the lower handle and raise the 
rear of the grass bag up toward your chest. The 
grass bag will open and the grass clippings will 
disperse. When replacing the grass bag, be sure 
the top of the bag rests on the wire support 
between the handles.

SECTION 6:  MAKING ADJUSTMENTS

Handle Height 

Your mower is shipped with the handle in the higher 
height position. To lower the height, proceed as follows:

Remove the starter rope from the rope guide.

Remove the wing nuts and carriage bolts securing 
the upper handle. Remove and lay the upper 
handle out of the way, being careful not to bend or 
kink the cables.

Remove the hairpin clips from the weld pins on the 
handle brackets and remove the wing nuts and 
carriage bolts from the upper hole on the handle 
mounting bracket. 

Press out on the legs of the lower handle and 
remove lower handle from the mower.

Turn lower handle around so the notch on the 
bottom of the lower handle is facing forward.
See Figure 12.

Figure 12

Reassemble the handles, placing the bottom holes 
in the handle over the weld pins in the handle 
mounting bracket.

Place the hairpin clips in the inner holes in the weld 
pins and insert the carriage bolts through the upper 
hole on the handle mounting bracket and secure 
with plastic wing nuts.

Reassemble the upper handle to the lower handle.

Attach the starter rope as instructed on page 8. 

WARNING: 

Do not operate the mower 

without mulching baffle, discharge chute or 
grass catcher properly installed.

WARNING: 

If the mower strikes a foreign 

object, stop the engine. Remove spark plug 
wire from the spark plug and thoroughly inspect 
for any damage. Repair the damage promptly 
before restarting and operating the mower. 

WARNING: 

Do not at any time make any 

adjustments without first stopping engine and 
disconnecting spark plug wire.
