WHAT’S IN THE BOX
The following suggestions will enable you to observe good working practices, keep yourself and
fellow workers safe and maintain your tools and equipment in good working order.
Good Working Practices/Safety
Mains Powered Tools
!
WARNING!! KEEP TOOLS AND EQUIPMENT OUT
OF THE REACH OF YOUNG CHILDREN
Primary Precautions
These tools are supplied with a moulded 13 Amp. Plug and 3 core power cable. Before using the tool
inspect the cable and the plug to make sure that neither are damaged. If any damage is visible have the
tool inspected/repaired by a suitably qualified person. If it is necessary to replace the plug, it is preferable
to use an ‘unbreakable’ type that will resist damage on site. Only use a 13 Amp plug, and make sure the
cable clamp is tightened securely. Fuse as required. If extension leads are to be used, carry out the same
safety checks on them, and ensure that they are correctly rated to safely supply the current that is required
for your machine.

GENERAL INSTRUCTIONS FOR 230V MACHINES
Work Place/Environment
The machine is designed for indoor use, do not use when or where it is liable to get wet. If the tool is to be
used outside and it starts to rain (unusual though this would be in U.K.), stop work and move it inside. If
tool has got wet; dry it off as soon as possible, with a cloth or paper towel. Do not use 230Va.c. powered
tools anywhere within a site area that is flooded or puddled, and do not trail extension cables across wet
areas. Keep the tools clean; it will enable you to more easily see any damage that may have occurred.
Clean the tool with a damp soapy cloth if needs be, do not use any solvents or cleaners, as these may
cause damage to any plastic parts or to the electrical components.
Keep the work area as uncluttered as is practical, this includes personnel as well as material.
Under no circumstances should CHILDREN be allowed in work areas.
It is good practice to leave the tool unplugged until work is about to commence, also make sure to unplug
the tool when it is not in use, or unattended. Always disconnect by pulling on the plug body and not the
cable. Once you are ready to commence work, remove any tools used in the setting operations (if any) and
place safely out of the way. Re-connect the tool.
Carry out a final check e.g. check the cutting tool, drill bit etc., is securely tightened in the tool, check you
have the correct speed and function set, check that the power cable will not ‘snag’ etc. Make sure you are
comfortable before you start work, balanced, not reaching etc.
If the work you are carrying out is liable to generate flying grit, dust or chips, wear the appropriate safety
clothing, goggles, gloves, masks etc. If the work operation appears to be excessively noisy, wear
ear-defenders. If you wear your hair in a long style, wearing a cap, safety helmet, hairnet, even a
sweatband, will minimise the possibility of your hair being caught up in the rotating parts of the tool,
likewise, consideration should be given to the removal of rings and wristwatches, if these are liable to
be a ‘snag’ hazard. Consideration should also be given to non-slip footwear, etc.
If you are allowing another person to use the machine, ensure that they are suitably qualified to use it.
DO NOT use any tools or machinery if you are under the influence of drink, drugs or prescribed medication.
DO NOT work with cutting or boring tools of any description if you are tired, your attention is wandering or
you are being subjected to distraction. A deep cut, a lost fingertip or worse is not worth it!
DO NOT use this machine within the designated safety areas of flammable liquid stores or in areas where
there may be volatile gases. There are very expensive, very specialised machines for working in these areas,
THIS IS NOT ONE OF THEM.
Check that cutters, drills etc., are the correct type and size, are undamaged and are kept clean and
sharp, this will maintain their operating performance and lessen the loading on the machine. Above all,
OBSERVE…. make sure you know what is happening around you, and USE YOUR COMMON SENSE.

SPECIFIC SAFETY PRECAUTIONS FOR GRINDING MACHINES
1. DO NOT operate your machine until it is completely assembled and installed according to
the instructions.
2. If you are not familiar with the operation of grinding machines obtain advice from your
supervisor or instructor or another qualified person.
3. Only use grinding wheels or attachments rated higher than 3600 rpm with a 5/8” (16mm) arbor
on this machine.
4. NEVER use a chipped or cracked wheel. Always inspect each wheel before mounting it on
the grinder. If during inspection you discover a damaged grinding wheel; replace it immediately.
5. DO NOT over tighten wheel nuts.
6. Always maintain a distance of 1.5mm or less between the wheel and the tool rest. Adjust the
tool rests as the wheels decrease in size.
7. Ensure the tool rests are tightened so they cannot move while in use.
8. NEVER grind on a cold wheel. The grinder should always be run for at least one minute before
applying work to it.
9. NEVER grind on the side of the wheel. Always grind on the face of the wheel only.
10. NEVER apply coolant directly to a grinding wheel, it may cause the bonding to fail. If the
work piece becomes hot, dip it into a water pot to cool it down.
11. HOT SPARKS ARE A HAZARD! NEVER carry out grinding operations near flammable
material of any type (ie solid, gas, liquid).
12. Always make sure the spark guards and eye shields are in place, that they are properly
adjusted and secured.
13. Keep the sparks guards close to the wheels and re-adjust them as the wheels wear.
14. Ensure the soft washer and the flanges furnished with the grinder, are used to mount any
attachments (grinding wheels, wire brushes, buffing wheels, etc) onto the shaft.
15. Always stand to one side of the grinder when starting the machine.
16. Avoid awkward hand positions where a sudden slip could cause the hands to come into
contact with a grinding wheel, wire brush etc.
17. If the wheel requires dressing, dress only the front of the wheel, do not dress the sides.
18. DO NOT use any attachment that causes the machine to vibrate. If after changing grinding
wheels or adding attachments, the machine does vibrate; remove the recently replaced item and
change again.
19. Grinding creates heat. DO NOT touch the work face of the work piece until you are sure it has
cooled down sufficiently.

07
INITIAL ASSEMBLY
Carefully unpack the machine and all the loose items from the box. Check the contents against
the “What’s in the box” list. If any items are missing please contact our technical services
department using the telephone numbers that you will find in our catalogue. Having removed
all the items from the box, please dispose of your unwanted packaging responsibly. A lot of the
packaging is biodegradable.
Remove the protective coating from all unpainted parts. This coating may be removed with a soft
cloth moistened with paraffin (do not use acetone, petrol or lacquer thinners for this purpose).
Initially we suggest that you merely carry out a ‘loose’ assembly of the various parts of the
grinder. After assembly has been completed we will set up the various components correctly
and tighten securely.
Identify the Tool Rests and secure them to the inside faces of the wheel covers using the star
handled bolts and washers provided. (See fig 1).
Identify the Eye shield guards, these assemblies are universal and can be fitted to either side of
the machine. Secure into the hard point the top of the stone cover part of the guard, using the M4
screws etc. provided. (See figs 2 & 3).

SETTING UP THE GRINDER
Please read the section entitled Identification and Description of Parts, in order for you
to understand the terminology that we will use, so that you may better understand the
working and capability of your grinder. Keep this manual to hand for reference for any
other personnel that may be required to use the grinder.
Having assembled all the grinder attachments loosely, now the machine has to be set up
correctly and all the attachments securely fastened.
Place the grinder on a flat level surface.
Position the tool rests leaving a gap of approximately one and a half millimetres between the
grindstone and the rest, with the rest horizontal (preferably) tighten the star bolts securely. (See
fig 3)
Adjust the spark guards until they are just clear of the grindstone; fasten the fixing bolts securely.
(See fig 4)
Position the eye shields on their pivot bolts, (if necessary, ‘nip’ the clamping bolt of the eye
shield clamp so that the eye shields remain in place).
If there is any tendency for the grinder to move, tip or tilt while it is being operated, it should be
bolted down; either to the bench or to a specific stand, or base board. It is a good idea to dress
new grindstones before use, to remove any possible irregularities, and ensure the stones are
running concentrically.

SETTING UP THE GRINDER
Carry out a final check e.g. start the machine, check it runs smoothly. On each side, check that
the spark guard is adjusted down to the stone, check the gap between the tool rest and the stone
is correct, check the stone is not badly deformed (rounded edges, grooved face, etc; unless you
have specifically shaped the stone to these profiles)check the eye shield is correctly positioned.
Have a cooling pot to hand if you need it, and remember safety goggles are a good investment
(you are only issued with 1 pair of eyes).

IDENTIFICATION AND DESCRIPTION OF THE GRINDER
Grinding Essentially a double ended motor, with a mounting base, the motor
machine flanges mount the wheel guards. The motor base contains the NVR
switch and mounts the machine lamp. The base also has four 15mm
holes cast into it to facilitate mounting the grinder to a stand or bolting it
down to a bench.
Wheel guards Two formed metal guards that enclose the grinding wheels. They are
each formed in two parts. The inner part is mounted onto the motor
flange, and the outer part is bolted to it. There are various ‘hard point
locations’ with captive nuts fitted, that accept the fixing bolts that secure
the attachments of the machine.
Tool rests Formed castings that comprise the tool rest mounting arm and the tool
rest proper. They are bolted into two hard points on the lower inside
edges of the wheel guards.
Eye shield/ Clear protective shields with an integrated magnifiying glass for close up
spark guards inspection of work that mount over the grindstone to afford a view of the
workpiece, but offer protection for the eyes, They are mounted onto the
spark guards making a complete assembly that bolts through a hard point
on the upper part of the stone cover. The spark guard itself has an
elongated slot to allow positioning and adjustment as the wheel diameter
decreases. Their function is to contain any material (esp. sparks) that
would be tracked around the grindstone and sprayed out of the machine
esp. over the hands.
Work light Integral worklight, with flexible ‘move and stay’ column, energised with the
application of the mains power.
ON/OFF switch NVR switch, marked as standard with ‘I’ indicating ON and ‘O’ indicating
OFF.
Hold down holes Four holes that are formed in the base casting to enable the grinder to be
bolted down to the bench or a stand.
Dust extraction There are two 40mm dust extraction ducts integrated to the wheel guards
Ducts for the purpose of attaching a dust extractor.

CHANGING A GRINDING WHEEL
Nut Plate flange
Loosen the nut holding the grinding wheel to the shaft. Carefully remove the left handed nut,
the plate flange and the soft washer that is clamping the grindstone in place. (See figs 8 & 9)
Then, very carefully remove the grindstone from the shaft, take care that no damage or
distortion is done to the bush (if one is fitted). (See fig 10) Now is a good time to clean out
the interior of the wheel guard, removing any loose or compacted material that may have
accumulated. Carefully inspect the new grinding wheel before it is fitted, check that there are no
cracks, and there is no damage to either the front face or the edges. If required, fit the bush to
the grindstone. Carefully mount the grindstone onto the shaft, reposition the soft washer and
the wheel flange, replace the holding nut and tighten carefully. Do Not Overtighten. Refit the
outside shell of the wheel guard and secure with its nuts and bolts. Refit the tool rest, positioning
as in “Setting up the grinder”. Fasten securely.
Fig 6 Fig 7
Fig 8 Fig 9
ENSURE THAT THE GRINDER IS DISCONNECTED FROM THE
MAINS SUPPLY.
Undo the nuts and bolts that secure the outer shell of the wheel guard to the inner
shell. Remove the outer shell and place it and the nuts, bolts and washers
carefully aside. (See figs 6 & 7)
!

13
CHANGING A GRINDING WHEEL
Reset the spark guards and tool rest as for “setting up the
grinder” instructions. Reconnect the grinder to the mains
supply, give the grinder a ‘short burst’, by switching it on
and off quickly. Check the grinder is not subject to any
undue vibration. If the grinder does vibrate, strip it down
again and check that the bush (if fitted) is correctly
positioned and is the correct size for the stone and the
spindle. Check the bore of the stone is correct. If these all
seem correct refit and carryout the ‘quick burst’ procedure
again. If the machine is still vibrating, discard the stone
and replace with another one. Run up to speed normally.
Leave the machine running for at least one minute before
carrying out any work. Apply a workpiece and check that
the spark guard is correctly positioned and that the tool
rest is securely fixed.
If necessary dress the new stone lightly to ensure a ‘good
face’ and concentricity.
Fig 10
DRESSING A STONE
If the grindstones wear unevenly, producing crests, dips or rounded edges, they should
be dressed out using a suitable wheel dressing tool. (A selection of stone dressing tools are
available in the Axminster catalogue.)
Switch the grinder on and allow it to run for at least one minute. Rest the dressing tool on the
tool rest and advance it to the stone until it touches the maximum diameter; gently move the
dresser back and forth across the face of the stone until all irregularities have been removed
and the edges of the stone are nice and sharp.
!
PLEASE NOTE
!
This is not a procedure that can be
rushed, it must be carried out
slowly and steadily.
