NOTE

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure. The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period. An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period. Identify additional safety

measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

5.3 Further safety instructions for all saws with the Kickback causes and related warnings

The kickback is a sudden reaction to a pinched, bound or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator; s and the blade is pinched or bound tightly by the kerf lowering down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator; e of the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by intaking proper precautions as given below.

ork to

- a) Maintain a firm grip with both hands on the s a and position your arms to resist kickback force Position your body to either side of the blade,

notinlinewiththeblade. Kickback could cause the Riving knife function

saw to jump backwards, but kickback forces can controlled by the operator, if proper precautions are taken.

b) When blade is binding, or when interrupting cut for any reason, release the trigger and the saw motionless in the material until it comes to a complete stop. Never attempt move the saw from the work or pull the ward while the blade is in motion or kid may occur. Investigate and take corrective action to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, the saw blade in the kerf and check that teeth are not engaged into the material. blade is binding, it may walk up or kickback from workpiece as the saw is restarted.
d) Support large panels to minimise the risk pinching and kickback. Large panels tend to under their own weight. Supports must be placed under the panel on both sides, near the line of and near the edge of the panel.
e) Do not use dull or damaged blades. Unsh or improperly set blades produce narrowkerfcausin excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking lev must be tight and secure before making blade adjustment shifts while cutting, it may cause binding and kickback.
g) Use extra caution when sawing into existir or other blind areas. The protruding blade m objects that can cause kickback.

5.4 Lower guard function

a) Check lower guard for proper closing before use. Do not operate the saw if lower guard not move freely and close instantly. Never or tie the lower guard into the open position is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle make sure it moves freely and does not touch the blade or any other part, in all angles and depths cut.
b) Check the operation of the lower guard s If the guard and the spring are not ope properly, they must be serviced before us guard may operate sluggishly due to damaged pa gummy deposits, or a build-up of debris.
c) Lower guard may be retracted manually or special cuts such as "plunge cuts" and "pound cuts." Raise lower guard by retract handle and as soon as blade enters the ial, the lower guard must be released. For sawing, the lower guard should operate automatically.
d) Always observe that the lower guard is c the blade before placing saw down on b floor. An unprotected, coasting blade will cause saw to walk backwards, cutting whatever is in its path. Be a ware of the time it takes f stop after switch is released.

be a) Use the appropriate saw blade for the riving knife. For the riving knife to function, the body of the blade must be thinner than the riving knife and the cutting width of the blade must be wider than the thickness of the riving knife.
the blade b) Adjust the riving knife as described in this in- to re- struction manual. Incorrect spacing, positioning and saw back- alignment can make the riving knife ineffective in pre- ckback venting kickback.
18c) Always use the riving knife except when plunge cutting. Riving knife must be replaced after plunge centre cutting. Riving knife causes interference during at saw plunge cutting and can create kickback.
For the riving knife to work, it must be enga in the workpiece. The riving knife is ineffective in preventing kickback during short cuts.
of the blade Do not operate the saw if riving knife is bent. a light interference can slow the closing rate of a guard.
