ASSEMBLY
<2mm
<2mm
All the following components must be fitted correctly before
using the bench grinder.
• Spark Deflectors - These are provided to prevent sparks
from re-entering the grinding wheel assembly. The gap
between the spark deflector and the face of grinding wheel
is adjustable and should be kept at a distance of 2mm.
Fitted in two parts, the mounting bracket and the deflector.
Firstly, screw the mounting bracket to the wheel guard as
shown in Fig.2 then fix the deflector to the mounting
bracket, setting it at a distance of 2mm from the grinding
wheel. see Fig.3
INSTALLATION
The bench grinder must be placed on a flat, horizontal and stable surface. The bench grinder should be
fixed to something heavy enough, so that it will not move whilst in use.
Attach the bench grinder using screws or nuts and bolts using the four 8mm fixing holes provided at the
base of the unit.
Whilst all care is taken during assembly, it is strongly recommended the grinding wheels are removed,
examined and refitted before use.
When using the bench grinder for the first time, it should be allowed to run for at least five minutes
before it is subjected to grind a work piece.
OPERATION
Remember to wear the appropriate personal protective equipment.
Check that the machine is assembled and adjusted correctly then switch on the machine.
The machine must reach full speed before any grinding work commences.
For best results use the coarse grinding wheel first followed by the medium grinding wheel.
Rest the workpiece on the Work Support to eliminate chatter then add a small amount of pressure to
grind away to the desired amount.
Grinding Wheel Handling and Storage
All grinding wheels can be easily damaged by mishandling that results in the wheel being subjected to any
shock loading. This can occur by inadvertently dropping, knocking or banging against any other object.
Any grinding wheel subjected to such mishandling should be carefully examined for signs of damage.
If in doubt do not use.
During storage, grinding wheels must not be subjected to:
Humidity, water or other liquids. Freezing temperatures. Any temperature low enough to cause the
formation of condensation.
• Eye Shields - Protect from grinding
debris which is thrown out at a
high velocity and can damage
your eyes. The eyeshields are
fitted to the top of the spark
deflectors using a 50mm Cross
Head Cap Screw, nut and
washers.
Before changing an eye shield
ensure that the machine is
switched off. Always ensure that
eyeshields are undamaged and
fitted securely before operating
the machine.
• Work Supports - Used to provide a firm and stable support to rest
the work piece on. The distance between the work support and
grinding wheel is adjustable, checked frequently and should be
kept at a distance of 2mm.
