placed under the panel on both sides, near the line of cut and near the edge of the panel.

e)Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf caus- ing excessive friction, blade binding and kickback.

f)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.

g)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.

5.2.3Safety instructions for circular saws with dual-actuation of lower blade guard or with trailing guard

a)Check lower guard for proper closing before each use. Do not operate the 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.

b)Check the operation of the lower guard spring. If the guard and the spring are not operating prop- erly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.

c)Lower guard should be retracted manually only for special cuts such as “plunge cuts” and “com- pound cuts.” Raise lower guard by retracting handle and as soon as blade enters the ma- terial, the lower guard must be released. For all other sawing, the lower guard should operate automatically.

d)Always observe that the 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.

5.2.4Additional safety instructions for all saws with riving knife

a)Use the appropriate riving knife for the blade being used. For the riving knife to work, it must be thicker than the body of the blade but thinner than the tooth set of the blade.

b)Adjust the riving knife as described in this in- struction manual. Incorrect spacing, positioning and alignment can make the riving knife ineffective in preventing kickback.

c)Always use the riving knife except when plunge cutting. Riving knife must be replaced after plunge cutting. Riving knife causes interference during plunge cutting and can create kickback.

d)For the riving knife to work, it must be engaged in the workpiece. The riving knife is ineffective in preventing kickback during short cuts.

e)Do not operate the saw if riving knife is bent. Even a light interference can slow the closing rate of a guard.

5.2.5Personal safety

a)Wear ear protectors. Exposure to noise can cause hearing loss.

b)Always hold the power tool securely with both hands on the grips provided. Keep the grips dry, clean and free from oil and grease.

c)Breathing protection must be worn if the power tool is used without a dust extraction system for work that creates dust.

d)Do not operate the power tool without the pro- tective devices that belong to it.

e)Operate the power tool only as intended and when it is in faultless condition.

f)Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers during breaks between working.

g)Switch the power tool on only after bringing it into position at the workpiece.

h)Remove the battery before storing or transporting the power tool.

i)Always guide the power tool away from your body when working with it.

j)Do not work with the power tool overhead.

k)Do not attempt to brake the speed of the saw blade by pressing it to the side.

l)Do not touch the clamping flange or the flange screw while the power tool is running.

m)The kerf must be free of obstructions. Do not saw into screws and nails etc.

n)Never press the drive spindle lockbutton while the saw blade is rotating.

o)Never direct the power tool toward persons.

p)Adjust the pressure applied to the saw blade and the material being cut so that the blade doesn’t
