INSTALLING AND ADJUSTING THE GRINDING WHEEL
GUARD
The wheel guard protects the operator against flying broken
pieces and accidental contact with a working tool or sparks.
The guard should always be fitted. Special attention should be
paid so that its covering part faces the operator.
• The design of the wheel guard mounting allows for toolless
setting of the guard in an optimum position.
• Loosen and pull back the lever (10) on the wheel guard (4).
• Rotate the wheel guard (4) in a selected position.
• Lock by lowering the lever (10).
The removal and adjustment of the wheel guard are performed
in a reverse order to its installation.
REPLACEMENT OF WORKING TOOLS
When working tools are replaced, wear working gloves at all
times.
The spindle lock button (1) is only designed to lock the grinder
spindle, when a working tool is installed or removed. Do not
use it as a braking button, when the wheel rotates. Otherwise,
the grinder may become damaged or the user may be injured.
INSTALLING THE WHEELS
When grinding or cut-off wheels with the thickness below 3
mm are installed, the outer flange nut (5) should be tightened
with the flat surface from the wheel side (fig. B).
• Press the spindle lock button (1).
• Insert the special key (included) into two holes of the outer
flange (5) (fig. A).
• Rotate the key to loosen and remove the outer flange (5).
• Place the wheel so it is pressed against the surface of the inner
flange (6).
• Tighten the outer flange (5) and slightly tighten it with the
special key.
The wheel is removed in the reverse order. During installation,
the wheel should be pressed against the surface of the inner
flange (6) and seated centrally in the neck.
INSTALLING THE WORKING TOOLS WITH THREADED HOLES
• Press the spindle lock button (1).
• Remove a previously installed working tool, if it is installed.
• Both flanges should be removed before installation – the inner
flange (6) and outer flange (5).
• Put the threaded part of a working tool onto the spindle and
slightly tighten.
Working tools with threaded holes are removed in the reverse
order.
INSTALLING THE ANGLE GRINDER ON A TRIPOD FOR
ANGLE GRINDERS
The angle grinder can be used on a dedicated tripod for angle
grinders, provided that it is correctly installed according to
instructions of the manufacturer of a tripod.
OPERATION / ADJUSTMENTS
Before the grinder is used, check condition of the grinding
wheel. Do not use chipped, broken or otherwise damaged
grinding wheels. Worn grinding wheel or brush should be
immediately replaced with new one before use. Once your
work is completed, you should switch off the grinder and wait
until it comes to a complete stop. Only then the grinder can be
put aside. Do not brake a rotating grinding wheel by pressing
it against a workpiece.
• Do not overload the grinder. The weight of the power tool
exerts sufficient pressure to efficiently work with the tool.
Overloading and excessive pressure may lead to dangerous
cracking of the working tool.
• If the grinder is dropped during operation, it should be
checked and a working tool might need to be replaced,
when it is damaged or deformed.
• Never strike the workpiece with a working tool.
• Do not use the grinding wheel for hammering or stripping
of the workpiece, especially when corners, sharp edges are
worked, etc. (this may cause loss of control of the power tool
and recoil).
• Do not use discs from circular saws intended for wood
cutting. Failure to observe this recommendation may result
in recoil of the power tool, loss of control and may lead to
injuries of the operator.
SWITCHING ON /SWITCHING OFF
When the grinder is switched on and operated, it should be
held with both hands.
• Press the rear part of the switch (2).
• Move the switch (2) forwards - (towards the head) (fig. C).
• Press the front part of the switch for continuous operation.
• The switch will be automatically locked in the position for
continuous operation.
• Press the rear part of the switch (2) to switch the tool off.
Once the grinder is switched on, wait until the grinding wheel
reaches maximum speed and only then you can begin to work.
During operation do not use the switch to switch the grinder
on and off. The grinder switch can be used only when the
power tool is moved away from the workpiece.
The tool is equipped with a switch with undervoltage
release feature. In case of temporary mains power failure or
connecting to mains socket with switch in ON position, the
tool will not start. In such case move the switch to OFF position
and switch it on again.
SPEED ADJUSTMENT
The speed adjustment dial (8) (fig. D) is located in the upper rear
part of the grinder casing. The adjustment range is from 1 to 6.
The rotational speed can be changed depending on your needs.
CUTTING
• The angle grinder can be used for cutting in a straight line
only.
• Do not cut a workpiece holding it in your hands.
• Large workpiece should be supported. Make sure the
support points are located near the cutting line and at the
ends of the workpiece. A stably located workpiece will not
tend to move, when it is cut.
