CIRCULAR SAW SAFETY WARNINGS AND INSTRUCTIONS
Support large panels to minimise the risk of blade 
pinching and kickback. Large panels tend to sag under 
their own weight. Supports must be placed under the 
panel on both sides, near the line of cut and near the 
edge of the panel.
Do not use dull or damaged blades. Unsharpened 
or improperly set blades produce narrow kerf causing 
excessive friction, blade binding and kickback.
Blade depth and bevel adjusting locking levers must be 
tight and secure before making cut. If blade adjustment 
shifts while cutting, it may cause binding and kickback.
Use extra caution when making a “plunge cut” into 
existing walls or other blind areas. The protruding blade 
may cut objects that can cause kickback.
Check lower guard for proper closing before each use. 
Do not operate saw if lower guard does not move freely 
and close instantly. Never clamp or tie the lower guard 
into the open position. If saw is accidentally dropped, 
lower guard may be bent. Raise the lower guard with the 
retracting handle and make sure it moves freely and does 
not touch the blade or any other part, in all angles and 
depths of cut. 
Check the operation of the lower guard spring. If the 
guard and the spring are not operating properly, they 
must be serviced before use. Lower guard may operate 
sluggishly due to damaged parts, gummy deposits, or a 
build-up of debris.
Lower blade guard handle should be retracted manu-
ally only for special cuts, such as “plunge cuts” and 
“compound cuts.” Raise lower guard by retracting 
handle and as soon as blade enters the material, the 
lower guard must be released. For all other sawing, the 
lower guard should operate automatically.
Always observe that the lower guard is covering the 
blade before placing saw down on bench or floor. An 
unprotected, coasting blade will cause the saw to walk 
backwards, cutting whatever is in its path. Be aware of the 
time it takes for the blade to stop after switch is released.
ADDITIONAL SAFETY RULES
Hold power tools by insulated gripping surfaces when 
performing an operation where the cutting tool may 
contact hidden wiring or its own cord. Contact with a 
“live” wire will make exposed metal parts of the tool “live” 
and shock the operator.
Know your power tool. Read operator’s manual care-
fully. Learn its applications and limitations, as well 
as the specific potential hazards related to this tool. 
Following this rule will reduce the risk of electric shock, 
fire, or serious injury.
Always wear eye protection with side shields marked 
to comply with ANSI Z87.1. Failure to do so could result 
in objects being thrown into your eyes, resulting in pos-
silbe serious injury.
Protect your lungs. Wear a face or dust mask if the 
operation is dusty. Following this rule will reduce the 
risk of serious personal injury.
Protect your hearing. Wear hearing protection during 
extended periods of operation. Following this rule will 
reduce the risk of serious personal injury.
Inspect tool cords periodically and, if damaged, have 
repaired at your nearest authorized service center. 
Constantly stay aware of cord location. Following this 
rule will reduce the risk of electric shock or fire.
Check damaged parts. Before further use of the 
tool, a guard or other part that is damaged should 
be carefully checked to determine that it will operate 
properly and perform its intended function. Check for 
alignment of moving 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 service center. Following this rule will 
reduce the risk of shock, fire, or serious injury.
Make sure your extension cord is in good condi-
tion. When using an extension cord, be sure to use 
one heavy enough to carry the current your product 
will draw. A wire gauge size (A.W.G.) of at least 14 is 
recommended for an extension cord 25 feet or less 
in length. A cord exceeding 100 feet is not recom-
mended. If in doubt, use the next heavier gauge. The 
smaller the gauge number, the heavier the cord. An 
undersized cord will cause a drop in line voltage resulting 
in loss of power and overheating.
Inspect for and remove all nails from lumber before 
using this tool. Following this rule will reduce the risk of 
serious personal injury.
Do not wear loose clothing or jewellery. Contain long 
hair. Loose clothes, jewellery, or long hair can be drawn 
into air vents.
Do not use on a ladder or unstable support. Stable 
footing on a solid surface enables better control of the 
tool in unexpected situations.
If the power supply cord is damaged, it must be 
replaced only by the manufacturer or by an authorized 
service center to avoid risk.
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.
