5) Service

a) Have your power tool serviced by a qualiﬁ ed

repair person using only identical replacement

parts.

This will ensure that the safety of the power tool is

maintained.

PRECAUTION

Keep children and inﬁ rm persons away.

When not in use, tools should be stored out of reach of

children and inﬁ rm persons.

SAFETY INSTRUCTIONS FOR ALL

SAWS

Cutting procedures

DANGER: Keep hands away from cutting area

and the blade. Keep your second hand on auxiliary

handle, or motor housing.

If both hands are holding the saw, they cannot be cut by

the blade.

b) Do not reach underneath the workpiece.

The guard cannot protect you from the blade below the

workpiece.

c) Adjust the cutting depth to the thickness of the

workpiece.

Less than a full tooth of the blade teeth should be visible

below the workpiece.

d) Never hold the workpiece in your hands or across

your leg while cutting. Secure the workpiece to a

stable platform.

It is important to support the work properly to minimize

body exposure, blade binding, or loss of control.

e) Hold the power tool 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 also make exposed metal

parts of the power tool "live" and could give the operator

an electric shock.

f) When ripping, always use a rip fence or straight

edge guide.

This improves the accuracy of cut and reduces the

chance of blade binding.

g) Always use blades with correct size and shape

(diamond versus round) of arbour holes.

Blades that do not match the mounting hardware of the

saw will run oﬀ -centre, causing loss of control.

h) Never use damaged or incorrect blade washers or

bolt.

The blade washers and bolt were specially designed

for your saw, for optimum performance and safety of

operation.

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 reaction

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 ﬁ rm 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 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 properly,

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

ﬂ oor.

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.
