Operation And Maintenance - GRAPHITE 58G003 Manual Del Usuario

• Remove previously installed working tool, if any.
• Remove two flanges before installation: inner flange (7) and outer
flange (6).
• Screw threaded part of the working tool onto the spindle, then
slightly tighten.
Remove working tools with threaded hole by following installation
procedure in reversed order.
INSTALLATION OF THE ANGLE GRINDER ON AN ANGLE
GRINDER SUPPORT
It is possible to use the angle grinder in special support for angle
grinders. The angle grinder must be correctly fixed in accordance
with installation procedure provided by the support manufacturer.
OPERATION / SETTINGS
Check the grinding wheel condition before using the grinder. Do
not use wheels with dents, cracks or other damages. Replace worn
out wheel or brush with a new one before operation. After work
is finished always switch the grinder off and wait until the work
tool comes to complete stop. Only then you can put the grinder
away. Do not brake rotating grinding wheel by pushing it against
processed material.
• Do not overload the grinder. The power tool weight creates
enough pressure to work efficiently. Overloading and too
strong pressure may cause dangerous crack of the working tool.
• In case the grinder is dropped during operation, make sure
to check and replace the working tool when necessary, if it is
found damaged or deformed.
• Never hit processed material with working tool.
• Avoid knocking off and tearing off material with the wheel,
especially when processing knives, sharp edges etc., as this can
cause loss of control over the power tool and kick back.
• Never use wood cutting blades designed for circular sawing
machines. Use of such blades often results in the power tool
kickback, loss of control and may cause operator body injury.
SWITCHING ON / SWITCHING OFF
Hold the grinder with both hands when starting and during
operation. The grinder is equipped with the switch, which protects
against accidental starting.
• Press the switch lock button (2).
• Press the switch button (3) (fig. F).
• Releasing the switch button (3) will stop the grinder.
Wait a while after starting the grinder until the wheel reaches
its top speed; only then you can proceed with your work. When
working, do not use the switch of the grinder to switch it on or off.
Switch button may only be used when the grinder is away from
the processed material.
CUTTING
• Use the angle grinder to make cuts in straight line only.
• Do not cut material while holding it in hand.
• Support large pieces and make sure that points of support
are located near the cutting line and near end edges of the
material. Stable material does not tend to shift during cutting.
• Fix small pieces, e.g. in a vice or with clamps. Fix material so the
cutting place is located near fixing tool. This will ensure greater
precision when cutting.
• Do not allow vibrations or cutting wheel bouncing on material,
it can adversely affect cut quality and may cause crack in the
cutting wheel.
• When cutting, do not apply side pressure on a cutting wheel.
• Use cutting wheel appropriate for the type of processed
material.
• When cutting, it is recommended to match advance direction
with direction of cutting wheel rotation.
Cutting depth depends on the wheel diameter (fig. G).
• Use only wheels with rated diameters equal or smaller than
recommended for the given grinder type.
• In case of deep cutting (e.g. sections, building blocks, bricks etc.),
avoid contact of fixing flanges with processed material.
Cutting wheels heat up to high temperatures during operation –
do not touch them with unprotected parts of your body before
they cool down.
GRINDING
With the angle grinder you can use grinding wheels, cup wheels,
flap wheels, wheels with abrasive cloth, wire brushes, elastic
discs for abrasive paper etc. Each type of wheel and processed
material requires the right working technique and use of
appropriate personal protection equipment.
When grinding do not use wheels designed for cutting.
Grinding wheels are designed to remove material with wheel
edge.
• Do not use side surface for grinding. Optimum work angle for
such wheels is 30° (fig. H).
• Perform grinding tasks only with grinding wheels appropriate
for processed material.
When using flap wheels, abrasive cloth wheels and elastic discs
with abrasive paper make sure to keep the right work angle (fig. I).
• Do not use whole wheel surface for grinding or sanding.
• Such wheels are used for processing flat surfaces.
Wire brushes are mainly used for cleaning sections and hard to
reach areas. Use them to remove rust, paint coatings, etc. (fig. K).
Use only working tools whose allowable rotary speed is higher or
equal to maximum angle grinder speed with no load.

OPERATION AND MAINTENANCE

Remove the battery from the device 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 dry cloth 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.
• In case of excessive commutator sparking, have the technical
condition of carbon brushes of the motor checked by a qualified
person.
• Always store the tool in a dry place, beyond reach of children.
• Store the device with the battery removed.
All defects should be repaired by service workshop authorized
by the manufacturer.
