Cleaning

Under side of rear deck

Remove grass and debris.

Washing

Regular cleaning and washing, especially under the 

mower deck, will increase the machine’s lifespan. 

make it a habit to clean the machine directly after use, 

before the dirt sticks. Do not spray high pressure water 

directly on the top of the deck. Do not spray hot engine 

or exhaust.

8062-012

Clean mower deck after each use

Hardware

Check daily. Inspect the entire machine for loose or 

missing hardware.

WARNING!

Escaping hydraulic oil under pressure 

can have sufficient force to penetrate 

the skin, causing serious injury. 

If injured by escaping fluid, see a 

doctor at once. Serious infection 

or reaction can develop if proper 

medical treatment is not administered 

immediately.
