GENERAL SAFETY RULES

Avoid body contact with grounded surfaces such as metal 

pipes and wire fences. There is an increased risk of electric 

shock if your body is grounded.

n

  Do not operate a chain saw that is damaged, improperly 

adjusted,  or  not  completely  and  securely  assembled. 
Chain should slow to a stop when the switch trigger is 
released. If the chain continues to turn after the switch 
trigger has been released, have the unit serviced by your 
nearest Ryobi service dealer.

n

  Check for damaged parts. Check for alignment of mov-

ing  parts,  binding  of  moving  parts,  breakage  of  parts, 
mounting, and any other conditions that may affect its 
operation. A guard or other part that is damaged should 
be properly repaired or replaced by an authorized ser-
vice dealer unless otherwise indicated elsewhere in this 
manual.

n

  All chain saw service, other than the items listed in the 

operation and maintenance sections, should be performed 
by your nearest Ryobi service dealer.

n

  Always maintain a proper stance.

n

  Do not use chain saw if switch does not turn it on and off. 

Have defective switches replaced by authorized service 
center.

n

  Do not adapt your powerhead to a bow guide or use it 

to power any attachments or devices not listed for the 
saw.

n

  Disconnect chain saw when not in use, before servicing, 

and when making adjustments and changing attachments, 
such as saw chain and guard.

n

  Do not cut vines and/or small underbrush.

n

  Do not operate a chain saw in a tree, on a ladder, or scaf-

fold; this is extremely dangerous.

    

NOTE:

  The  size  of  the  work  area  depends  on  the  job 

being performed as well as the size tree or work piece 
involved. For example, felling a tree requires a larger work 
area than making bucking cuts.

n

  Use extreme caution when cutting small size brush and 

saplings, because small material may catch the saw chain 
and be whipped toward you or pull you off balance.

n

  When cutting a limb that is under tension, be alert for 

spring back so that you will not be struck when the ten-
sion in the wood fibers is released.

n

  Do not force the chain saw. The job can be performed 

better and safer at the rate for which it was intended.

n

  Always use the right product for your application. The 

chain saw should be used for cutting wood only. Never 
use the chain saw to cut plastic, masonry or non-wood 
building materials.

n

  Do not use the chain saw for purposes not intended.

n

  Store chain saw when not in use. Chain saw should be 

stored in a dry and high or locked area out of the reach 
of children. When storing chain saw place the scabbard 
on the bar and chain and store the chain saw in carrying 
case.

Save these instructions. 

Refer to them frequently and 

use them to instruct others who may use this tool. If you 
loan  someone  this  tool,  loan  them  these  instructions 
also.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals 
known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to 
these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks 
that are specially designed to filter out microscopic particles.
