Operation And Maintenance - GRAPHITE 58G491 Traducción Del Manual Original

OPERATION / SETTINGS
SWITCHING ON / SWITCHING OFF
The mains voltage must match the voltage on the rating plate of
the saw. Hold the saw with both hands when starting up, because
engine torque may cause uncontrolled turn of the power tool.
Remember that rotating parts of the saw rotate for some time
after the tool has been switched off.
The saw is equipped with the switch lock button (16) that protects
against accidental start up.
Switching on:
• Press the switch lock button (16) (fig. C).
• Press the switch button (15).
Switching off:
• Release pressure on the switch button (15).
VOLTAGE INDICATOR
When the saw is connected to power supply socket, the voltage
indicator lamp (3) lights up
CUTTING
Cutting line is defined by cutting line indicators (7) and (8).
• When starting operation always hold the saw firmly with both
hands by two handles.
• Switch on the circular saw only when it is away from the material
that is to be cut.
• Do not press the saw too hard. Pressure should be moderate and
continuous.
• After the cut is finished allow the cutting blade to stop completely.
• If the cutting is aborted before the task is completed, prior to
continuation start the saw and allow for idle operation. Wait until
the tool achieves its full rotational speed and then carefully drive
the cutting blade into the kerf in the processed material.
• When cutting perpendicular to fibres of material (wood), fibres
tend to lift up and tear off (moving the saw slowly minimizes this
effect).
• Ensure the lower guard reaches its extreme position.
• Before starting to cut always make sure that cutting depth locking
knob and knobs for base bevel adjustment are tightened firmly.
• With the circular saw use only cutting blades with correct arbour
hole and outer diameter.
• Processed material must be firmly fixed.
• Place wider part of the saw base on the part of the material, which
is not cut off.
If the object is small, fix the processed material with F-clamps. If
the circular saw base does not move on the processed material,
but is lifted instead, there is danger of kick back.
Properly fixed processed material and firm hold of the tool ensure
full control over power tool operation. This allows to avoid risk of
body injury. Do not try to hold short pieces of material with your
hand.
BEVEL CUTTING
• Loosen the knob for base bevel adjustment (5) (fig. D).
• Use the scale to set the saw base (9) to appropriate angle (from
0° to 45°).
• Tighten the knob for base bevel adjustment (5).
Be aware that the risk of kick back is greater for bevel cutting
(pinching of cutting blade more probable), therefore it is
particularly important that the saw base rests on the processed
material with its whole surface. Perform cutting with smooth move.
MAKING A CUT BY PLUNGING INTO MATERIAL
Disconnect the saw from power supply before starting any
adjustments.
• Set desired cutting depth that matches thickness of material
planned to be cut.
• Tilt the saw so the front edge of the saw footplate (9) rests on the
cut material and 0° marker for perpendicular cutting is in the line
of planned cutting.
• When the saw is in the place to start cutting, lift the lower guard
(13) with the lower guard lever (4) (cutting blade is lifted above
the material).
• Switch the power tool on and wait until cutting blade reaches its
full rotational speed.
• Gradually lower the saw and plunge the cutting blade in material
(during this move front edge of the saw base should have contact
with surface of the material).
• When the blade starts cutting, release the lower guard.
• When whole surface of the saw base rests on the material, move
the saw forward to proceed with cutting.
• Never move the saw backwards when the blade is rotating, there
is danger of kick back.
• Finish cutting in reverse order it was started, by turning the saw
around line of contact of the processed material and the front
edge of the tool base.
• Before removing blade from the material, allow it to stop after
switching the saw off.
• Finish the corner fillets with reciprocating saw or hand saw when
necessary.
CUTTING OR CUTTING OFF LARGE PIECES OF MATERIAL
When cutting large boards of material support them to avoid
potential blade hitch (kick back) due to pinching the blade in
material kerf.

OPERATION AND MAINTENANCE

Unplug the power cord from the mains socket before commencing
any activities related to installation, adjustment, repair or
maintenance.
MAINTENANCE AND STORAGE
• Cleaning the device after each use is recommended.
• Do not use water or any other liquid for cleaning.
• Clean the tool with a brush or blow through with compressed air
at low pressure.
• Do not use any cleaning agents or solvents, they may damage
plastic parts.
• Clean ventilation holes in the motor casing regularly to prevent
device overheating. Do not clean ventilation holes by inserting
sharp objects there, such as screwdrivers and other similar objects.
• In case of power cord damage replace it with a cord with the same
specification. Entrust the repair to a qualified specialist or return
the tool to a service point.
• In case of excessive commutator sparking, have the technical
condition of carbon brushes of the motor checked by a qualified
person.
• During normal operation cutting blade gets blunt after some
time. When it happens it is necessary to apply greater pressure
when moving the saw during cutting.
• When cutting blade is found damaged, replace it immediately.
• Cutting blade must always be sharp.
• Always store the tool in a dry place, beyond reach of children.
CUTTING BLADE REPLACEMENT
• Use supplied hexagonal key to unscrew the fixing bolt for cutting
blade (12) by turning it counter-clockwise.
• To prevent rotation of saw spindle, lock the spindle with spindle
lock button (19) when unscrewing the bolt that fixes the cutting
blade (fig. E).
• Disassemble outer flange washer (11).
• Use lower guard lever (4) to move lower guard (13) so it hides
maximally in the upper guard (2) (check condition and operation
of the spring that pulls the lower guard at that time).
• Slide the cutting blade (10) out through the slit in the saw base (9).
• Position new cutting blade so blade teeth and arrow on the blade
match direction of the arrow on the upper guard.
