Kickback causes and related warnings

– kickback is a sudden reaction to a pinched, jammed

or misaligned saw blade, causing an uncontrolled saw

to lift up and out of the workpiece toward the operator;

– when the blade is pinched or jammed tightly by the

kerf closing down, the blade stalls and the motor reac-

tion drives the unit rapidly back toward the operator;

– if 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 taking proper precautions as given below.

a) Maintain a firm grip with both hands on the saw

and position your arms to resist kickback forces.

Position your body to either side of the blade, but

not in line with the blade. Kickback could cause the

saw to jump backwards, but kickback forces can be

controlled by the operator, if proper precautions are

taken.

b) When blade is binding, or when interrupting a

cut for any reason, release the trigger and hold

the saw motionless in the material until the blade

comes to a complete stop. Never attempt to remove

the saw from the work or pull the saw backward

while the blade is in motion or kickback may occur.

Investigate and take corrective actions to eliminate the

cause of blade binding.

c) When restarting a saw in the workpiece, centre

the saw blade in the kerf so that the saw teeth are

not engaged into the material. If a saw blade binds, it

may walk up or kickback from the workpiece as the saw

is restarted.

d) 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.

e) Do not use dull or damaged blades. Unsharpened

or improperly set blades produce narrow kerf causing

excessive friction, blade binding and kickback.

f) Blade depth and bevel adjusting locking levers

must be tight and secure before making the cut.

If blade adjustment shifts while cutting, it may cause

binding and kickback.

g) Use extra caution when sawing into existing

walls or other blind areas. The protruding blade may

cut objects that can cause kickback.

Lower guard function

a) Check the lower guard for proper closing before

each use. Do not operate the saw if the lower guard

does not move freely and close instantly. Never

clamp or tie the lower guard into the open position. If

the saw is accidentally dropped, the lower guard may

be bent. Raise the lower guard with the retracting hand-

le 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 proper-

ly, they must be serviced before use. Lower guard

may operate sluggishly due to damaged parts, gummy

deposits, or a build-up of debris.

c) The lower guard may be retracted manually

only for special cuts such as „plunge cuts" and

„compound cuts". Raise the lower guard by the

retracting handle and as soon as the blade enters

the material, the lower guard must be released.

For all other sawing, the lower guard should operate

automatically.

d) Always observe that the lower guard is covering

the blade before placing the 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 and Working Instructions

Wear ear protectors. Exposure to noise can cause

hearing loss.

Use protective equipment. Always wear safety glasses

when working with the machine. The use of protective

clothing is recommended, such as dust mask, protec-

tive gloves, sturdy non-slip footwear, helmet and ear

defenders.

The dust produced when using this tool may be harmful

to health. Do not inhale the dust. Use a dust absorp-

tion system and wear a suitable dust protection mask.

Remove deposited dust thoroughly, e.g. with a vacuum

cleaner.

Do not use saw blades not corresponding to the key

data given in these instructions for use.

It is necessary to select a saw blade which is suitable

for the material being cut.

Use only woodworking blades specified in this manual,

which comply with EN 847-1.

The rated speed of the accessory must be at least

equal to the maximum speed marked on the power tool.

Do not fix the on/off switch in the „on" position when

using the saw hand-held.

Do not use abrasion discs in this machine!

Remove the battery pack before starting any work on

the appliance.

WARNING! To reduce the risk of fire, personal injury,

and product damage due to a short circuit, never im-

merse your tool, battery pack or charger in fluid or allow

a fluid to flow inside them. Corrosive or conductive

fluids, such as seawater, certain industrial chemicals,

and bleach or bleach containing products, etc., Can

cause a short circuit.

Never break open battery packs and chargers and

store only in dry rooms. Keep dry at all times.
