Starting the Mower
WARNING
Poisonous Gas Hazard
Engine exhaust contains carbon monoxide, a poisonous
gas that could kill you in minutes. You CANNOT see it,
smell it, or taste it. Even if you do not smell exhaust fumes,
you could still be exposed to carbon monoxide gas. If you
start to feel sick, dizzy, or weak while using this product,
shut it off and get to fresh air RIGHT AWAY. See a doctor.
You may have carbon monoxide poisoning.
• Operate this product ONLY outside far away from
windows, doors and vents to reduce the risk of carbon
monoxide gas from accumulating and potentially being
drawn towards occupied spaces.
• Install battery-operated carbon monoxide alarms or
plug-in carbon monoxide alarms with battery back-up
according to the manufacturer's instructions. Smoke
alarms cannot detect carbon monoxide gas.
• DO NOT run this product inside homes, garages,
basements, crawlspaces, sheds, or other partially-
enclosed spaces even if using fans or opening doors
and windows for ventilation. Carbon monoxide can
quickly build up in these spaces and can linger for
hours, even after this product has shut off.
• ALWAYS place this product downwind and point the
engine exhaust away from occupied spaces.
The engine on your mower is equipped with the Briggs &
Stratton Ready Start™ System. This features a temperature-
controlled automatic choke. No additional steps are required
to start a cold engine.
1. Squeeze the blade control (A, Figure 5) against the
handle.
2. Pull the rope start handle (B) to start the engine.
3. To stop the engine (and blade), release the blade control.
4. After the engine starts, allow a brief warm-up until the
engine runs smooth before beginning mower operation.
Propelling the Mower
1. Start the mower.
2. Move the ground speed control (A, Figure 6) to the
desired speed position.
3. Squeeze the wheel drive control (B) against the handle
to engage the wheel drive and propel the mower forward.
Forward speed can be adjusted while the mower is
moving by changing the position of the ground speed
control.
Stopping the Mower
1. Stop forward motion of the mower by releasing the wheel
drive control.
2. Stop the engine and blade by releasing the blade control.

WARNING
Amputation Hazard
• DO NOT attempt any maintenance, adjustments or
service with engine and blade running.
• STOP engine and blade.
• Disconnect spark plug wire and secure away from spark
plug.
Burn Hazard
• Engine and components are HOT.

1. Loosen the lower nuts (A, Figure 7) on each lower
handle.

Cutting Height Adjustment
WARNING
Amputation Hazard
• DO NOT attempt any maintenance, adjustments or
service with engine and blade running.
• STOP engine and blade.
• Disconnect spark plug wire and secure away from spark
plug.
Burn Hazard
• Engine and components are HOT.
• Avoid serious burns, allow sufficient time for all
components to cool.
1. Pull the height adjusting latch (A, Figure 8) outward and
move to the desired cutting height.
2. Set all wheels at the same cutting height. The highest
cutting position is Notch 7 (Figure 9). The lowest cutting
position is Notch 1.
Mulching Operation
For best mulching results, cut up to a maximum of 1/3 of
grass blade length and recycle ONLY when grass is dry.
1. Set all wheels in the highest cutting position (Notch 7).
See Cutting Height Adjustment .
2. Move the engine speed control to the fast (Rabbit)
position.
3. Move the ground speed control to the slowest speed
setting.
4. Proceed mowing slowly. If the grass is very dense, lower
each rear wheel latch one notch lower than the front
wheel latches to improve mulching performance.
