heavy-dutytool. Don't usetoolfor purpose notintended; for example, don't
use circular saw for cutting tree limbs or logs.
7. DRESSPROPERLY. Don't wear loose clothingorjewelry. They canbe caught

when working outdoors. Wear protective hair covering tocontain longhair.
8. USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
9. DON'T ABUSE CORD. Never carry toolby cordor yank it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
IO. SECURE WORK. Use clamps or a vise to hold work. It's safer than using

14. REMOVEADJUSTING KEYS AND WRENCHES. Form habit of checking to
seethat keys andadjusting wrenches are removed from tool before turning
it on.
15. AVOID UNINTENTIONALSTARTING.Don't carry tool with finger onswitch.
Be sure switch is
OFF when plugging in.
16. EXTENSION CORDS. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry
the current your product
will draw. An undersized cord will cause a drop
in line voltage resulting in loss of power and overheating. Table 1 showsthe
correctsize touse depending oncord lengthand nameplateampere rating.
If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

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
service center unless otherwise indicated elsewhere in this instruction
manual. Havedefective switches replacedby authorizedservice center. Don't
