Starting Engine

WARNING: 

Be sure no one other than the operator 

is standing near the lawn mower while starting 

engine or operating mower. Never run engine 

indoors or in enclosed, poorly ventilated areas. 

Engine exhaust contains carbon monoxide, an 

odorless and deadly gas. Keep hands, feet, hair and 

loose clothing away from any moving parts on 

engine and lawn mower.

Pull out the choke knob located on the left side of the 

1. 

upper handle. See Fig. 5-1.

NOTE: 

Use of the choke may not be necessary if the engine 

is warm or the air temperature is high.

2. 

Standing behind the mower, squeeze and hold the blade 

control against upper handle.

3. 

Pull the recoil starter lightly until resistance is felt, then pull 

rapidly to overcome compression, prevent kickback, and 

start the engine. Repeat if necessary. See Fig. 5-1.

NOTE: 

Do not allow the recoil starter to snap back against 

the rope guide.

4. 

When engine warms up, push in the choke knob.

Stopping Engine

Release blade control to stop the engine and blade.

1. 

WARNING: 

Wait for the blade to stop completely 

before performing any work on the mower or to 

remove the side discharge chute. 

Using Your Lawn Mower

Be sure 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.

Once the engine is running, squeeze the drive control 

1. 

against the upper handle to propel the mower. Release it to 

disengage the drive.

WARNING: 

If you strike a foreign object, stop the 

engine. Remove wire from the spark plug, 

thoroughly inspect mower for any damage, and 

repair damage before restarting and operating. 

Extensive vibration of mower during operation is an 

indication of damage. The unit should be promptly 

inspected and repaired.

Using as Mulcher

For mulching grass, remove the grass catcher or side discharge 

chute from the mower and reinstall the mulching baffle. For 

effective mulching, do not cut wet grass. If the grass has been 

allowed to grow in excess of four inches, mulching is not 

recommended. Use the grass catcher  to bag clippings instead.

WARNING: 

The operation of any lawn mower can 

result in foreign objects being thrown into the eyes, 

which can damage your eyes severely. Always wear 

safety glasses while operating the mower, or while 

performing any adjustments or repairs on it.

Using Grass Catcher

You can use the grass catcher bag to collect clippings while 

you are operating the mower. The grass bag is equipped with 

a bag-fill indicator to add convenience to your work. While the 

mower is running, air will flow through the bag and into the 

Grass Gauge. If the grass catcher is empty, air flows through 

easily pushing the gauge up. If the grass catcher is full, air does 

not flow through it allowing the gauge to fall. So the position of 

the gauge acts as a bag-fill indicator signifying when to empty 

the grass bag.

Attach grass catcher following instructions in “Setup and 

1. 

Adjustment”. Grass clippings will automatically collect in 

the bag as you run the mower.

Operate the mower till the grass bag is full.

2. 

Stop engine completely by releasing the blade control. 

3. 

Make sure that the unit has come to a complete stop.
While holding the grass bag by both the rear handle and 

4. 

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.
Continuing to hold the lower handle, raise the rear of the 

5. 

grass bag and release the lower handle over a proper 

receptacle. 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.
