GENERAL SAFETY PROCEDURES

For any questions regarding the hazard and safety notices listed in this manual or on the product, please
call [phone] Mon-Fri 9-5 EST before using the engine.

DANGER: CARBON MONOXIDE

Using an engine indoors CAN KILL YOU IN MINUTES. Engine exhaust contains carbon
monoxide (CO). This is a poison gas you cannot see or smell. I f you can smell the engine exhaust, you are
breathing CO. But even if you cannot smell the exhaust, you could be breathing CO.

NEVER use an engine inside homes, garages, crawlspaces, or other partly enclosed areas. Deadly levels
of carbon monoxide can build up in these areas. Using a fan, or opening windows and/or doors will NOT
properly vent CO nor supply adequate fresh air. ONLY use an engine outside and far away from
windows, doors, and vents. These openings can pull in engine exhaust.

Even if you use an engine correctly, CO may leak into the home. ALWAYS use a battery-powered or
battery-backup CO alarm in the home. If you start to feel sick, dizzy, or weak after the engine has been
running, move to fresh air RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.

WARNING: The exhaust from this product contains chemicals known to th e State of California to cause
cancer, birth defects, or other reproductive harm.

WARNING: This engine may emit highly flammable and explosive gasoline vapors, which can cause
severe burns or even death if ignited. A nearby open flame can lead to explosion even if it isn’t directly in
contact with gasoline.

• Do not operate near an open flame.

• Do not smoke near the engine.

• Always operate on a firm, level surface.

• Always turn engine o ff b efore refu eli ng. All ow engine to cool for at least 2 minutes before

removing fuel cap. Loosen cap slowly to relieve pressure in tank.

• Do not overfill fuel tank. Gasoline may expand during operation. Do not fill to the top of the tank.

Allow for expansion.

• Always check for spilled fuel before operating.

• Empty fuel tank before storing or transporting the engine.

WARNING: This engine produces heat when running. Temperatures near exhaust can exceed 1500F
(650 C).

IMPORTANT SAFETY INSTRUCTIONS

General Operation

Read, understand, and follow all instructions on the machine and in the manual(s) before starting.

1. Do not put hands or feet near or under the machine. Keep clear of the discharge opening at all times.

2. Only allow responsible adults, who are familiar with the instructions, to operate this machine.

3. Clear the area of objects such as rocks, wire, toys, etc., which could be thrown by the blade. Stay

behind the handle when the engine is running.

4. Be sure the area is clear of bystanders before operating. Stop machine if anyone enters the area.

5. Do not operate machine barefooted or while wearing sandals. Always wear substantial footwear.

6. Do not pull machine backward unless absolutely necessary. Always look down and behind before and

while moving backward.

7. Never direct discharged material toward anyone. Avoid discharging material against a wall or

obstruction. Material may ricochet back toward the operator. Stop the blade when crossing gravel
surfaces.

8. Do not operate machine without the entire grass catcher, discharge guard, rear guard, or other safety

protective devices in place and working.

9. Never leave a running machine unattended.

10. Stop the engine and wait until the blade comes to a complete stop before cleaning the machine,

removing grass catcher, or unclogging the discharge guard.

11. Operate machine only in daylight or good artificial light.

12. Do not operate machine while under the influence of alcohol or drugs.

13. Never operate mower in wet grass. Always be sure of your footing; walk; never run.

14. Disengage the drive system, if so equipped, before starting the engine.

15. If the machine should start to vibrate abnormally, stop the engine and check for the cause

immediately. Vibration is generally a warning of trouble.

16. Always wear eye protection when operating machine.

17. See manufacturer's instructions for proper operation and installation of accessories. Only use

accessories approved by the manufacturer.

Slope Operation

Slopes are a major factor related to slip and fall accidents, which can result in severe injury. Operation on
all slopes require extra caution. If you feel uneasy on a slope, do not mow it.

1. Mow across the face of slopes; never up and down. Exercise extreme caution when changing

direction on slopes.

2. Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could cause a slip and

fall accident. Tall grass can hide obstacles.

3. Do not mow on wet grass or excessively steep slopes. Poor footing could cause a slip and fall

accident.

4. Do not mow near drop-offs, ditches, or embankments. You could lose your footing or balance.

Children

Sever injury can occur if the operator is not alert to the presence of children in the immediate area.
Children are often attracted to the mowing activity. Never assume that children will remain where you
last saw them.

1. Keep children out of the mowing area and under the watchful care of a responsible adult other than

the operator.

2. Be alert and turn mower off if a child enters the area.

3. Never allow children under the age of 16 to operate the lawn mower.
