5. ASSEMBLY
WARNING! Ensure that the grinder is unplugged from the power supply before assembly.
5.1.
Fitting the Guard Assembly. (SG125EU)
5.1.1
The guard may be orientated at any angle to suit the grinding task required and should be positioned to allow maximum working
performance whilst providing maximum personal protection for the operator.
5.1.2
Take the guard and place it around the spindle as in fig.4, place the securing plate (fig.4B) around the spindle and line up the holes in the
plate with the holes in the main unit as in fig.4 and secure with screws (fig.4A).
5.2.
Attaching a Grinding/Cutting Disc.
(Discs should only be fitted by a person holding a grinding wheel certificate).
5.2.1
Lay the grinder on it's back and place the clamping flange onto the centre spindle with the raised ring facing upwards (see fig.2 item 5).
Rotate the clamping flange on the spindle unil the flats on its back face drop into alignment with the flats on the spindle. When the
clamping flange is in the correct position it can no longer be rotated on the spindle.
5.2.2
Place the grinding (or cutting) disc over the spindle and onto the clamping flange. Figures A, B & C (fig.8) section 7. CONSUMABLES
shows the correct orientation of the retaining flange nut for the different types of disc.
5.2.3
When using a grinding disc with a depressed centre portion as in Fig.A, Screw the disc retaining flange nut onto the spindle with the
raised ring facing downwards.
5.2.4
When using flat cutting discs as in Fig.C and cutting discs with a depressed centre portion as in Fig.B, screw the disc retaining flange nut
onto the spindle with the raised ring facing upwards.
5.2.5
Stop the spindle from turning by pushing in and holding the disc stop button (see fig.2.7).
5.2.6
Lock the grinding disc into place by tightening the disc retaining flange nut with the pin wrench (fig.2 item 4).
5.2.7
When complete, release the locking button and check that it has sprung back to its initial position.
5.3.
Fitting the Hand Grip.
Always use the hand grip for better control and improved safety. Fit the hand grip (fig.1.3) by screwing it into the appropriate left, right or
top position on the grinder head as indicated in fig.2.

6. OPERATION
WARNING! Ensure grinder is unplugged from the mains power supply before changing accessories.
6.1
PREPARATION
6.1.1
Attach grinding/cutting disc according to section 5.2. and position the handle grip conveniently for the task.
6.1.2
Ensure the disc safety guard is correctly positioned.
6.1.3
Plug grinder into the mains power supply.
WARNING! When the grinder first starts it will kick to the right. You must ensure, therefore, that the tool is securely gripped in both hands.
Especially important is the position you choose for the side handle in order to maintain stability.
WARNING! Before use, ensure that you are wearing approved safety goggles, ear defenders, appropriate dust mask if dust will
be generated and safety gloves, and that all other safety instructions in Section 1 are followed carefully.
6.2.
ON/OFF Switch (SG125EU)
6.2.1
Once plugged into the mains power supply the grinder is started by a two stage switching operation. Place your fingers over the switch
and using your index finger unlock the trigger by pushing the lock lever forwards and then squeeze the trigger into the 'ON' position.
(See fig.7)
6.2.2
To stop the grinder release the trigger.
6.2.3
When the trigger is released and returns to the 'OFF' position it is automatically locked to prevent inadvertent starting.
6.2.4
The trigger can be locked in the 'ON' position for continuous running. To do this release the lock and squeeze the trigger as previously
described. With the trigger fully depressed push the lock lever one stage further forward. Whilst maintaining pressure on the lock lever
release the trigger which will now stay in the 'ON' position.
6.2.5
To stop the grinder squeeze the trigger to unlock it and release the trigger.
6.2.6
If the power is cut to the grinder whilst the switch is locked 'ON' always release the trigger and unplug the grinder. DO NOT reconnect the
grinder until you are sure that the power has been restored.
6.4
GRINDING
6.4.1
The key to effective operating is controlling the pressure and surface contact between the disc and the workpiece.
WARNING! DO NOT switch the grinder on whilst the disc is in contact with the work piece. Bring the rotating disc to the workpiece.
6.4.2
Allow the disc to reach full speed before starting to grind.
6.4.3
Grind flat surfaces at an angle of between 10° to 20° to the work piece. Too great an angle will cause a concentration of pressure in one
small area resulting in gouging or burning of the surface.
6.4.4
When grinding is complete allow the workpiece to cool. DO NOT touch the hot surface.
6.4.5
Unplug the grinder from the mains power supply, clean and store in a safe, dry, childproof area.
