f)
Always use a rip fence or straightedge when ripping.
This improves the
accuracy of the cut and reduces the risk of blade fray.
g)
Always use blades with the correct size and shape (diamond shaped
versus round) of the shaft holes.
Blades that do not match the saw's
mounting hardware will run eccentrically, causing loss of control.
h)
Never use damaged or wrong blade rings or bolts.
The blade rings and the
bolt are specially designed for your saw, for optimum performance and safe
operation.
i)
Only use saw blades recommended by the manufacturer that comply
with EN 847-1.
j)
Do not use grinding wheels.
k)
Tools may only be used by persons with training and experience, who
know how to use and handle tools.
l)
The maximum rotational speed indicated on the tool must not be
exceeded.
Where indicated, the speed range must be observed.
m)
Circular saw blades with cracked saw body should be scrapped
(repair is
not permitted).
n)
The use of loose rings or sleeves to "supplement" the bore dimensions
of circular saw blades is not permitted;
the use of fixed rings, e.g. pressed
or bonded, in circular saw blades or in flange sleeves for other tools is
permitted if they are made in accordance with the manufacturer's
specifications.
Further safety instructions
Causes and prevention of kickback by the operator:
- Kickback is a sudden reaction to a clamped, bound or misaligned saw
blade, causing an uncontrolled saw lift up and out of the workpiece in the
direction of the operator;
- When the blade is pinched or clamped by the kerf closing down, the blade
locks and the reaction of the motor quickly drives the device back towards
the operator;
- If the blade becomes twisted or misaligned during the cut, the teeth on the
back of the blade may dig into the top of the wood, causing the blade to
climb out of the kerf and recoil in the direction of the operator.
- Kickback is the result of improper use of the saw and/or improper work
procedures or conditions and can be prevented by taking the proper
precautions, as indicated below.
a)
Hold the saw firmly with both hands and position your arms to prevent
kickback forces. Position your body on either side of the saw blade, but
not in line with it.
Kickback can cause the saw to jump backwards, but the
force of the kickback can be controlled by the operator if proper precautions
are taken.
b)
If the guide bar is jammed or you interrupt a cut for any reason, release
the trigger and hold the saw motionless in the material until the guide
bar has come to a complete stop. Never try to remove the saw from the
work or pull the saw backwards while the blade is moving, otherwise
kickback may occur.
Investigate and take corrective measures to eliminate
the cause of jamming of the blades.
