Instruction & User Manual
Safety instructions for the
handling of saw blades
m
Only use saw blade if you have mastered
their use.
m
Observe the maximum speed. The
maximum speed specified on the saw blade
may not be exceeded. If specified, observe
the speed range.
m
Observe the motor / saw blade direction of
rotation.
m
Do not use any saw blades with cracks.
Dispose of cracked saw blades. Repairs are
not permitted.
m
Clean grease, oil and water off of the
clamping surfaces.
m
Do not use any loose reducing rings or
bushes for the reducing of holes on saw
blades.
m
Make sure that fixed reducer rings for
securing the saw blade have the same
diameter and have at least 1/3 of the cutting
width.
m
Make sure that fixed reducer rings are
parallel to each other.
m
Handle the saw blade with caution. They
are ideally stored in the originally package or
special containers. Wear protective gloves in
order to improve grip and to further reduce
the risk of injury.
m
Prior to the use of saw blades, make sure
that all protective devices are properly
fastened.
m
Prior to use, make sure that the saw blade
meets the technical requirements of this
electric tool and is properly fastened.
m
Only use the supplied saw blade for cutting
wood and plastic, never for the processing
of metals.
Tips for Mitre Saw Blade
Maintenance
m
Avoid excessive moisture or humidity.
Otherwise, the blades may rust and/or pit.
m
Keep the saw blades clean to maintain good
performance. Accumulated pitch, sap, and
other materials may dull the blade, require
more push-through force, and generate
increased levels of heat through friction.
m
When cleaning the blades, never use a
wire brush. Otherwise you are likely to do
serious damage. Use a nylon or brass brush.
m
It’s important to avoid overheating the
blade by keeping it too low when cutting
hardwood. This can create a thermal crack
in the carbide, causing tip fragments to fly
backward to possibly injure the operator.
m
Never rest circular saw blades on steel or
cement surfaces. Metal on metal or metal
on cement can dull the blade by chipping
the top grind. Instead, it’s better to set the
blade down on plywood or plastic.
m
Always use the proper type of shipping
container. Be sure that the blades do not
rub against one another, or you are likely
to get chipping. It is recommended that
heavy cardboard be used or two pieces of
plywood with a bolt through them to create
a small container.
