WARNING!

 

Never operate this chain saw with  

one hand! One-handed operation 

could cause you to lose control, 

causing serious injury to yourself or 

others! A chain saw is intended for 

two-handed use. 

 

Wear safety footwear, snug-fitting 

clothing, protective gloves, and 

eye, hearing, and head-protection 

devices while working with this 

chain saw.

 

Do not allow other persons to be 

near the chain saw when starting 

or running the chain saw. Keep 

bystanders and animals out of the 

work area.

 

Never allow young children or any 

person unfamiliar with chain saws to 

operate this saw! 

 

Clear the work area before using 

the saw. Never start cutting until you 

are sure you have a secure footing 

and have planned a retreat path 

from the falling tree. 

 

Before starting the saw engine, 

make sure nothing is touching the 

saw chain. 

 

Keep all parts of your body away 

from the saw chain whenever the 

engine is running! 

 

Stop the engine before carrying the 

saw. Carry the saw with the engine 

stopped, the guide bar and saw 

chain pointing to the rear, and the 

engine muffler away from your body. 

 

Stop the engine before setting the 

chain saw down.

 

Install the appropriate guide-bar 

chain cover before transporting  

the saw. 

Additional Safety Precautions

 

Never operate this chain saw if you 

are fatigued or if you are under the 

influence of alcohol, drugs, or any 

other substance that could affect 

your ability or judgement.

 

Never operate a saw that is 

damaged, improperly adjusted, 

or not completely and securely 

assembled.

 

Do not use this saw if the saw chain 

continues to move after the throttle 

control trigger is released.  

 

Use only Shindaiwa-recommended 

parts when repairing or servicing 

this saw. 

 

Use extra care when cutting a limb 

that is under tension! A limb under 

tension could spring back suddenly, 

causing you to lose control of the 

saw!

 

Use extreme caution when cutting 

smaller brush and saplings! Small-

diameter material may catch in the 

chain and be whipped toward you or 

pull you off balance, causing you to 

lose control of the saw! 

 

Operate the saw only in a well 

ventilated area. Exhaust gases 

and lubrication oil mist can cause 

serious injury or death.

 

Keep the saw handles dry, clean 

and free of oil or fuel mixture. 

 

Never operate any saw while 

in a tree unless you have been 

specifically trained to do so! 

 

Never perform service or repairs to 

this saw unless you are specifically 

trained and equipped to do so! 

 

Improper maintenance, use of 

nonconforming replacement 

components, or the removal of 

safety devices, such as the chain 

brake or any of the chain brake 

components, could result in 

serious injury. 

 

Never allow any part of your 

body near the clutch cover of an 

operating saw. 

 

Never operate a saw with 

damaged or missing anti-vibration 

cushions. Long-term exposure to 

vibration can damage your hands, 

in particular vascular, bone or 

joint, neurological or muscular 

disorders. For lowest vibration, 

replace damaged mounts 

immediately. Mounts hardened 

due to age or weathering should 

also be replaced.

 

Always maintain a firm footing 

while operating this saw! Ladders 

and other temporary platforms can 

shift unexpectedly, and are not 

recommended!

 

Do not operate this or any other 

chain saw with the muffler  

removed.

 

All chain saw service, other 

than items listed in the owner’s 

maintenance instructions, 

should be performed by trained 

Shindaiwa chain saw service 

personnel.

 

Prolonged exposure to excessive 

noise is fatiguing and could lead 

to impaired hearing. The use of 

proper ear protection could reduce 

this potential hazard.
