Restrict the use 

of this power machine 

to persons who read, 

understand 

and follow the warnings 

and instructions 

in this manual 

1.  Never run an engine indoors or in a poorly ventilated 

area. Engine exhaust contains carbon monoxide, an 

odorless, and deadly gas.

2.  Before cleaning, repairing, or inspecting, make certain 

the blade(s) and all moving parts have stopped. 

Disconnect the spark plug wire and ground against the 

engine to prevent unintended starting. 

3.  Periodically check to make sure the blades come to 

complete stop within approximately (5) five seconds 

after operating the blade disengagement control. If the 

blades do not stop within the this time frame, your unit 

should be serviced professionally by an authorized 

MTD Service Dealer.

4.  Check brake operation frequently as it is subjected to 

wear during normal operation. Adjust and service as 

required.

5.  Check the blade(s) and engine mounting bolts at 

frequent intervals for proper tightness. Also, visually 

inspect blade(s) for damage (e.g., excessive wear, 

bent, cracked).   Replace the blade(s) with the original 

equipment manufacturer’s (O.E.M.) blade(s) only, 

listed in this manual. “Use of parts which do not meet 

the original equipment specifications may lead to 

improper performance and compromise safety!” 

6.  Mower blades are sharp. Wrap the blade or wear 

gloves, and use extra caution when servicing them.

7.  Keep all nuts, bolts, and screws tight to be sure the 

equipment is in safe working condition.   

8.  Never tamper with the safety interlock system or other 

safety devices. Check their proper operation regularly.

9.  After striking a foreign object, stop the engine, 

disconnect the spark plug wire(s) and ground against 

the engine. Thoroughly inspect the machine for any 

damage. Repair the damage before starting and 

operating.

10. Never attempt to make adjustments or repairs to the 

machine while the engine is running.

11. Grass catcher components and the discharge 

cover are subject to wear and damage which could 

expose moving parts or allow objects to be thrown. 

For safety protection, frequently check components 

and replace immediately with original equipment 

manufacturer’s (O.E.M.) parts only, listed in this 

manual. “Use of parts which do not meet the original 

equipment specifications may lead to improper 

performance and compromise safety!”

12. Do not change the engine governor settings or 

over-speed the engine. The governor controls the 

maximum safe operating speed of the engine. 

13. Maintain or replace safety and instruction labels, as 

necessary. 

14. Observe proper disposal laws and regulations for 

gas, oil, etc. to protect the environment.
