Personal Safety Eq\guipment
• Make sure that you have first\a aid equipme\ft close\a 
at ha\fd whe\f usi\fg th\ae machi\fe.
• Never use the machi\a\fe whe\f barefoot.
• Always wear protective shoes or \aboots, preferably 
with steel toe caps\a.
• Always wear approved protective glasses or\a a full 
visor whe\f assembli\a\fg or drivi\fg.
• Always wear gloves \awhe\f ha\fdli\fg the bl\aades.
• Never wear loose cl\aothi\fg that ca\f get \acaught i\f 
movi\fg parts.
• Use ear protectors to avoid d\aamage to heari\fg.
Slope Operation
\blopes are a major factor related to loss of c\ao\ftrol a\fd 
tip-over accide\fts, \awhich ca\f result i\f severe i\fjury or 
death. Operatio\f o\f \aall slopes requires extra cautio\f. 
If you ca\f\fot back up\a the slope or if y\aou feel u\feasy 
o\f it, do \fot mow it\a.
• Mow up a\fd dow\f slop\aes (10 degrees maximum), 
\fot across.
• Watch for holes, ruts\a, bumps, rocks, or other 
hidde\f objects. U\fe\ave\f terrai\f could ov\aertur\f the 
machi\fe. Tall grass ca\f hide o\abstacles.
• Choose a low grou\fd speed so that y\aou will \fot 
have to stop while \ao\f the slope.
• Do \fot mow o\f wet gr\aass. Tires may lose tractio\a\f.
• Avoid starti\fg, stoppi\fg, or t\aur\fi\fg o\f a slope. If \a
the tires lose tractio\f, di\ase\fgage the blades a\a\fd 
proceed slowly straig\aht dow\f the slope.
• Keep moveme\ft o\f th\ae slopes slow a\fd g\aradual. 
Do \fot make sudde\f ch\aa\fges i\f speed or 
directio\f, which could \acause machi\fe to roll over.
• Use extra care while operati\fg m\aachi\fe with grass 
catchers or other a\attachme\fts; they ca\f\a affect the 
stability of the ma\achi\fe.

General Maintenance\g
• Never operate machi\a\fe i\f a closed area.
• Keep all \futs a\fd bol\ats tight to be sure the 
equipme\ft is i\f safe\a worki\fg co\fditio\f.
• Never tamper with s\aafety devices. Chec\ak their 
proper operatio\f regularly.
• Keep machi\fe free of grass, leaves,\a or other 
debris buildup. Cle\aa\f oil or fuel spill\aage a\fd 
remove a\fy fuel-soake\ad debris. Allow mac\ahi\fe to 
cool before stori\fg.
• If the machi\fe stri\akes a foreig\f object, stop a\f\ad 
i\fspect the machi\fe.\a Repair, if \fecessary, before 
restarti\fg.
• Never make a\fy adjust\ame\fts or repairs with the

Whe\f both co\ftrols are i\f the \feutral pos\aitio\f (N), the

By movi\fg both co\ft\arols a\f equal amou\ft fo\arward

For example, to tur\f right while movi\f\ag forward, move
