- Only hold the device by the insulated grips when performing jobs in which the tool
could make contact with hidden electrical cables or the device’s own cable.
- To make longitudinal cuts, always use a stop or a straight cutting guide. This will
provide greater cutting precision and will reduce the risk of jamming the blade.
- Always use the right size blades that adapt perfectly to the shape of the hole where
they are inserted (round or star shaped). Blades that do not fit correctly on the saw
support will wobble and cause a lack of control.
- Do not use unsuitable or damaged washers or bolts to attach the saw blades.
The blade washers and bolts have been designed specifically for this saw for safe,
optimum operation.
2.7 Reasons for Recoil and Instructions for Preventing Recoil
- Recoil is a sudden reaction that occurs when, due to a jammed or misaligned blade,
the device jerks, jumps away from the work piece without control and moves in the
direction of the operator.
- When the blade jams or gets stuck in the cutting groove, it becomes blocked and the
force of the motor jerks the device towards the operator.
- If the blade twists or the cutting angle is misaligned, the blade teeth at the back edge
of the blade can become jammed on the surface of the work piece, come out of the
cutting groove and jump in the direction of the operator.
Recoil is due to improper or unsuitable use of the saw and can be avoided by following
the precautionary measures listed below.
a) Grasp the saw with both hands and brace your arms so they stop any recoil.
Always keep your body positioned to the side of the cutting blade so it is never
in line with the blade. In the event of recoil, the circular blade can jerk back, but this
recoil can be controlled by the operator if suitable precautions are taken.
b) If the blade jams or you stop working, turn off the saw and hold onto the
work piece until the blade has come to a complete stop. Never attempt to remove
the blade from the work piece or pull the saw backward while the blade is moving
because this could cause recoil. Examine the blade to determine the cause of the jam
and correct the problem.
c) When you want to turn on the saw again when it is stuck in the work piece,
centre the blade in the cutting groove and make sure the teeth are not stuck in
the work piece. If the blade is jammed, turning the saw on again could make it come
out of the work piece and cause recoil.
d) Provide support for large panels to reduce the risk of recoil due to blade
jamming. Large panels can sag due to their own weight. Large panels should
be supported in two places: near the cutting groove and near the end of the panel.
e) Do not use damaged or dull blades. Blades with dull or poorly aligned teeth
produce a cut that is too narrow and cause excessive friction, blade jamming and recoil.
f) Before you start sawing, adjust the cutting depth and angle. If these
adjustments are changed during sawing jobs, the blade can jam and cause recoil.
g) Pay special attention when making plunge cuts into walls and hidden areas.
The blade may become jammed on hidden objects when sawing and cause recoil.
2.8 Safety Instructions for Saws with a Blade Guard
a) Before each use, make sure the blade guard closes properly. Do not use the
saw if the blade guard does not move freely and does not close immediately.
Never hold or clamp the guard into the open position. If the saw is accidentally
dropped, the guard may be bent. Make sure the guard moves freely and does not
make contact with the blade or any other part at all cutting angles and depths.
b) Check the condition and operation of the guard spring. If the spring or guard
does not work properly, have the saw repaired before using it. Damaged parts,
sticky residue or the accumulation of sawdust can make the blade guard work slower.
c) Apply pressure to the saw’s base plate so it does not move to the side during
perpendicular plunge cuts. Side movements can cause the blade to jam and cause
recoil.
d) Do not place the saw on the workbench or floor without checking if the blade
guard is covering the blade. A blade without protection that continues spinning due
to inertia makes the saw move in the opposite direction of the cutting direction while
it cuts everything in its way. Always bear in mind the time it takes for the saw blade
to stop spinning.
2.9 Additional Safety Instructions
a) The grip should be clean and dry and should be kept away from oil and grease.
b) Do not stop the cutting tool by pushing the blade to the side.
c) Any defective switches, protective parts or other components should be replaced
by an authorized technical service centre. Examine the extension lead regularly. If it is
damaged, it can only be replaced by the manufacturer or an authorized service centre.
d) When you use the tool outdoors, always connect a residual-current device.
e) Warning! If you want to use the saw at home, especially on floors, ceilings and
walls, always check to ensure that electricity, water and gas installations will not be
damaged. If necessary, use a metal detector, which can be acquired in specialized
shops. Bear in mind that in all houses there are usually hidden pipes and wiring
behind plaster and other types of covering, which means there is a risk of suffering
from an electric shock or other kind of accident, not to mention damaging the building.
2.10 Other Risks
Even if you follow the instructions while using this power tool, you will always
be exposed to some risks. Following is a description of the dangers associated
with the construction and design features of this tool:
a) Lung injuries if an anti-dust mask is not used.
b) Loss of hearing if suitable hearing protection is not used.
c) General health damage derived from the vibration of hands and arms if the tool is
used for a long period of time and does not receive suitable maintenance or control.
d) Cutting injuries if sharp objects are not handled with care and gloves are not worn.
Warning! When in operation, this power tool generates an electromagnetic field.
Under certain circumstances, this field can have a harmful effect on active and passive
medical implants. To reduce the risk of serious and fatal injury, people with medical
implants are recommended to consult their doctor and the implant manufacturer before
using this tool.
