Maintenance

• Save all instructions 

WARNING

In order to prevent accidental starting when setting up, 
transporting, adjusting or making repairs, always discon-
nect spark plug wire and place wire where it cannot come in 
contact with plug.

CAUTION

If the engine has been running, the muffler will be very hot. 

Be careful not to touch the muffler.

GENERAL

•  Always observe all safety warnings when performing any

 maintenance.

•   Maintain the mower with care.

•   Inspect the mower periodically. If the mower is not working 

 

  properly or damaged, have it repaired by a qualified 

  service center.

•   Do not change engine governor setting or overspeed the  

 engine.

•   Do not remove or modify any parts. Removing or modifying 

 

  parts could lead to injury, damage the mower and will  
  void the warranty.

•   Use only genuine replacement parts and accessories.

  Unapproved parts or accessories could lead to injury,   
  damage to the unit and void your warranty

•   Periodically check all fasteners and ensure they are tight.

LUBRICATION

Keep the unit well lubricated

•  Using a light lubricating oil to lubricate pivot points on the  

  blade control lever, wheels and mulcher door hinge.

IMPORTANT: 

Do not oil or grease plastic wheel bearings. 

Viscous lubricants will attract dust and dirt that will shorten 
the life of the self lubricating bearings. If you feel they
must be lubricated, use only a dry, powdered graphite type 
lubricant sparingly. 

•  Refer to the separate Engine Owner’s manual

 for lubrication  

  schedule and instructions for engine lubrication.

CLEANING

IMPORTANT: 

For best performance, keep mower hous-

ing free of grass build-up and trash. Clean the underside of 
your mower after each use.

WARNING

In order to prevent accidental starting when setting up,
transporting, adjusting or making repairs, always discon-
nect spark plug wire and place wire where it cannot come in 
contact with plug.

CAUTION

Always tip the mower so it is resting on the side of the deck

and the air filter side of the engine is facing up. Make sure 

the mower is resting in a stable position before beginning to 
clean the deck. Never tip the mower more than 90º in any
direction and do not leave the mower tipped for extended 
periods of time.

Oil can drain into the top part of the engine and cause starting 
problems.

•  Before cleaning the underside of the deck, always drain  

  the fuel tank by running the engine till the tank is empty.

•   Clean the underside of your mower by scraping to  

 

  remove build-up of grass and trash.

•   Keep finished surfaces and wheels free of all gasoline,  

  oil, etc.

•   We do not recommend using a garden hose to clean    

  mower unless the electrical system, muffler, air filter and  

  carburetor are covered to keep water out. Water in  

 

  engine can result in shortened engine life.
