using this equipment.
MAIN PARTS DIAGRAM
The following image of a typical electrical
version TCG250, the image and operation are
suitable to all 110V, 230V 415V variants.
The TCG250 comprises of a fabricated steel
chassis to which all other components are
mounted. Several dierent power units
are available including electric, petrol and
pneumatic options.
The power unit drives the heavy-duty cutter
drum via a pulley and belt enclosed within the
belt guard.
The handlebar can be adjusted to suit the
operator. For electric models power is connected
via a chassis mounted socket and supplied
commando (IEC number) plug.
Deadman’s handle and switch must be held
to allow the machine to start. The machine is
started via the starter switch box.. A spring-
loaded ‘jacking stand’ is built into the machine for
the purposes of taking the head out of contact
with the working surface to start, or store the
machine.
A separate industrial dust collector should be
connected to the vacuum port).
The chassis features an integrated
counterweight to ensure the machine remains
controllable while in operation.

SAFETY
Wear safety boots, face mask, shatterproof glasses, helmet,
gloves and any other personal protective equipment required
for the working conditions. Avoid loose clothing; this may
become trapped in moving parts and cause serious injury.
To avoid nuisance dust, connect an industrial vacuum cleaner
(minimum 3000watts or equivalent) to the 50mm (2”) vacuum
port situated at the rear of the machine.
Ensure that the workplace is well ventilated. Avoid operating
engine-powered machines in an enclosed area, since engine
exhaust gases are poisonous.
Be very careful with hot components. The exhaust and other
parts of the engine are hot during operation and can remain
hot for some time after shutdown.
Do not refuel the engine while the engine is hot or running,
there is a very real danger from explosion – always refuel
when the engine is cold, and in the open air.
During transportation fasten fuel cap tightly and close fuel tap.
Do not operate electric versions in wet conditions.
Caution this machine is heavy. It weighs between
(92kg/202lbs) and (144kg /317 lbs) dependent on power unit.
Do not lift this machine manually.
WARNING! Always observe safe-working practices at
all times.

RISK OF HAND-ARM VIBRATION INJURY
Media types and applications
These tools may cause Hand-arm Vibration Syndrome injury
if their use is not adequately managed. We advise you to
carry out a risk assessment and to implement measures
such as; limiting exposure time [i.e. actual trigger time, not
total time at work], job rotation, ensuring the tools are used
correctly, ensuring the tools are maintained according to
our recommendations, and ensuring that the operators wear
personal protective equipment [PPE] particularly gloves and
clothing to keep them warm. Employers should consider
setting up a programme of health surveillance to establish
a benchmark for each operator and to detect any early
symptoms of vibration injury.
We are not aware of any PPE that provides protection
against vibration injury by attenuating vibration emissions.
See ‘Specications’ section for vibration emission data.
Further advice is available from our Technical Department.
We strongly advise you to visit the Health & Safety
Executive website http://www.hse.gov.uk/vibration
This site provides excellent advice and information on HAV
and currently, includes a Hand-arm Vibration Exposure
Calculator that is easy to use to work out the daily vibration
exposure for each of your operators.
Trelawny Grinders are supplied with either a single grinding
disc incorporating 20 “segments” or the versatile grinding
“quick change” grinding blocks. Use of either from course
through to Hard will eectively address all hard or soft
concrete oor types. For more information contact your
Trelawny agent or Trelawny direct.
Grinding blocks
All can be used wet or dry.
Coarse grinding blocks
These are tted as standard on machines tted with the
grinding block option. These are designed for the rapid
removal of material. They produce a surface nish suitable
for directly laying oor coverings or for two part epoxy paint
coatings and for the rst grind of terrazzo oor surfaces.
Medium grinding blocks
These are less aggressive than the coarse blocks, they should
provide a surface nish suitable for painting or used as the
next stage to the coarse grinding blocks, when achieving
a polished surface on terrazzo tiles or other marble type
surfaces.
Fine grinding blocks
These are the least aggressive of all the grinding media. These
are generally only used for nal nishing to provide a surface
suitable for nal polishing.
In addition, scarifying blocks and wire brushes are available
which can be tted in place of the grinding blocks.

Machines tted with electric motors
Inspect the supply cable; Check that no damage has been
caused to the outer casing and that there are no exposed or
loose wires. Obtain the assistance of an electrician if a fault
is found. Do not use the machine until it has been rectied.
Check that the cable is not running across sharp or jagged
edges and that it is not in contact with any liquid.
It is recommended that the ‘jacking stand’ is employed to
start the machine. To engage the stand, tilt the machine to lift
the grinding head(s) and, whilst tilted, depress the foot pedal
(at the rear of the machine, between the wheels), keeping
it depressed whilst lowering the machine back towards its
normal working position. This action will result in the front
of the machine appearing slightly raised. To disengage the
stand ready for use, tilt the machine rearwards slightly and the
stand will be heard to retract. The grinding head(s) will now be
engaged with the working surface.
Turn red isolator knob to the “ON” position. The machine
is now energised. To start the machine, depress button
(“Deadman’s handle”) and keep depressed. As soon as the
button is released, the machine will stop.
PRE-START CHECK
ALL VERSIONS
Check all bolts and screws for tightness. Ensure that all ttings
are secure. Check the drive belts for correct tightness. There
should normally be approximately 13mm (1/2”) of free play
when the belt is depressed in the middle position between
the two pulleys. To check and set the belt tension, refer to the
Belt installation & Adjustment section.
The TCG250 is supplied with a specially commissioned
electric motors and starter switch assembly.
Each unit is fully tested and the overload relays have
been calibrated and set according to the manufacturer’s
specications.
In the event of malfunction on a new machine, the owner
should rst check that the power supply on site is suitable and
adequate.
All cables should be fully uncoiled and never left wrapped
around cable reels or tied in loops. The starter box is tted with
a safety feature to protect the motor and relays from damage.
Should an overload condition occur which triggers the thermal
overload within the starter, rotate the isolator switch to the
“OFF” position.
Note that the circuitry may have to cool down for a period
before the overload switch can reset itself upon depressing
the stop button.
The starter boxes are preset and under no circumstances
should they be tampered with, stripped down or adjusted,
otherwise it will invalidate the warranty.
110v Motor
The motor requires the minimum of a 32amp, 110v power
supply. Always use the shortest possible length of extension
cable. The 110v machine requires the use of 4mm2
extension cable up to a maximum of 20 metres, as it draws
a signicant operating current. The use of 2.5mm2 for 110v
machines is not recommended and can cause operating
problems, particularly in conjunction with poor supplies,
where excessive voltage drops will be encountered and
damage to the machine may occur. Use a centre tap
transformer with a continuous rated output of at least 3.0KVA.
In practice this means that a 5.0KVA transformer must be
used. Manufacturers have dierent methods of rating their
equipment. All transformers and cables should be tted
with 32amp plugs and sockets. The 230v supply to the 110v
transformers ideally should be rated to at least 20amp if
supply problems are to be avoided.
230v and 415v Motors
Take particular care when using 230v or 415v machines,
ensure that the electrical supply is earthed and that breakers
and fuses are correct for the loading. The 230v motor requires
the minimum of a 13amp, 220v power supply. The 415v motor
requires the minimum of a 10amp, 380v power supply. Always
use the shortest possible length of extension cable. To avoid
voltage drop the cable must have a minimum core wire size
of 2.5mm2cross-section area. Maximum length of cable 50
meters.
CAUTION! Beware of poisonous fumes coming from
engine versions. Start and operate only in well-ventilated
areas.
BE CAREFUL! The exhaust and other engine parts are hot
during and for some time after operation. Do not touch
them.
IMPORTANT! 415v 3 phase versions only: Ensure the supply
cable is of a 5 core construction and that all contacts
within the plug and socket are wired in accordance with
regulations. The control electronics require the neutral
circuit to be functional. If 4 core cable is used, where no
functioning neutral is present, the machine will not start
or run.

Machine Operation and Dust Suppression
Machines tted with petrol engines
Check that there is sucient fuel in the fuel tank.
(See manufacturer’s hand book for type.) Check that the
engine oil level is correct. (See pre-start check.) Ensure that
the machine is started on a level surface. Open the engine
fuel tap. For cold engine starting, the 5.5hp engines have an
automatic choke, apply full throttle to operate. Set the start
switch to the “on” position on Honda supplied engines.
To engage the stand, tilt the machine to lift the grinding
head(s) and, whilst tilted, depress the foot pedal (at the rear
of the machine, between the wheels), keeping it depressed
whilst lowering the machine back towards its normal working
position. This action will result in the front of the machine
appearing slightly raised. To disengage the stand ready for
use, tilt the machine rearwards slightly and the stand will be
heard to retract. The grinding head(s) will now be engaged
with the working surface.
Check that the machine has been raised on its stand. Pull the
‘hold to run’ lever against the handle bar. Pull the recoil starter
cord handle. After the engine starts, move the throttle lever
towards the idle/tick-over position until the engine
runs smoothly.
After a minute or two reduce to a quarter open throttle setting
and warm up the engine for a further 2~3 minutes before
setting to tick over. The warm up procedure is particularly
important during cold weather.
(Please refer to manual handling recommendations when
lifting.) Connect a suitable commercial vacuum which has
been designed for the collection of concrete dust and
possibly toxic paint particles, or for use in the pharmaceutical
or food industries, Trelawny can supply special HEPA ltered
vacuums which are suitable for these applications.
Or if suitable for the area being worked, connect a water hose
to the supplied connection at the rear of the machine.
On engine-powered machines, once the engine has reached
operating temperature and you are ready to start work, set
the throttle lever to the full throttle position, pull back on
the handle bars to retract the machines stand and slowly
lower the disc to the surface. The machine may oscillate
slightly during use, which is normal. Move the machine slowly
backwards and forwards, slightly swinging the grinding head
right and left; this will ensure that a uniform nish is achieved.
Complete a small area noting the performance; on engine
versions reduce the throttle to tick over and release the ‘hold
to run’ lever. Then on both engine and electric motor versions
release the ‘hold to run’ lever to stop the machine, inspect the
nish produced. If necessary change the grade of grinding
blocks or diamond discs and recheck performance and
surface nish.
IMPORTANT! Do not pull the recoil starter cord to the
end of its travel as it may cause damage to the engine
or injury to the operator. When the engine starts, recoil
the cord slowly. Do not allow the cord to snap back to its
start position.
EMERGENCY SHUTDOWN: Release the “hold to run
lever” on the handle bar and/or switch o the ignition
switch on Honda engine versions.

Belt Installation & Adjustment
Removal
Remove the top cover by unscrewing the two 8mm bolts
either side of the chassis. Loosen the engine/motor mounting
plate bolts and slide the engine/motor forward. Slide the belt
o the drive pulley and then remove it from the engine/motor
pulley.
Installation
Slide the new belt onto the engine/motor pulley rst, locating
the belt in the pulley’s teeth. Then slide onto into the teeth of
the drive pulleys.
Slide the engine/motor backwards until the slack in the belt is
taken up, gently nip the four bolts and ensure the slack in the
belt is correct (see note below). If the tension needs adjusting
move the motor mounting plate in the desired direction until
the correct tension is achieved. (see P.10, Pre-Start Check for
detail) Tighten all engine/motor mounting plate bolts fully,
ret the top cover and tighten the 8mm bolts.
Drive system maintenance
The drive system on the TCG250 is virtually maintenance free
and will give a long service life without attention providing the
belt tension is set correctly.
The belt may need changing occasionally, the bearings (29)
will require greasing after any lay up period and/or every 6
months or occasionally during heavy use.
Long period storage: over 3 months
Clean outside of machine, inspect the grinding blocks for
wear; replace any worn parts as required.
Remove any build up of material from inside of grinding disc
area following step in start of “Grinding Block Replacement”
Section. Cover the machine to protect it. Store the machine
in a dry place. Be sure to check security of wooden wedges
after any lay up period.
shut down
On electric-powered machines, simply release the “deadman’s
handle” button. On engine-powered machines, move the
engine’s throttle lever to the slow speed position. (This
avoids the engine becoming washed internally by neat fuel if
switched o from high engine revolutions.) Release the ‘hold
to run’ lever and on Honda engines, switch o the engine’s
start switch.
On both electric and engine-powered machines, use the
stand (operation of which is described on page 10, Starting)
to raise the disc o the ground to prevent any built up heat
deforming the rubber coupling if it is left under load whilst hot
and stationary. The machine can be stored whilst on its stand.
After the engine or motor has completely cooled, clean o
any concrete dust from external components and remove
any heavy build up of concrete dust from inside the front dust
skirt, (see start of “Grinding Block Replacement” section for
safe method of gaining access to inside of front dust skirt).
Take care when using hoses or pressure washers and clean
within the dust skirt area only.
Do not to allow water to be directed at or splashed onto the
engine, electric motor or any electrical components. Once
clean and dry, cover the machine to protect it and store the
grinder in a dry place.
IMPORTANT! Close the engine fuel tap
IMPORTANT! Normal slack should be approximately
13mm (1/2”) when the belts are depressed in the middle
position between the engine pulley and driveshaft
pulley.
This machine is specically produced for use on concrete and
steel oors. Do not modify, add components to or retrot the

Grinding Block Replacement
Switch o the engine-powered versions and allow the
engine to cool completely, disconnect electric-motor-
powered versions from its power supply. Place the machine
on a at and level surface. Raise the front skirt by loosening
the four 10mm guard retaining bolts on either side of the
machine and slide the guard up to the top of the slots, tighten
the bolts temporarily.
Electric Machines
Tilt the machine backwards to rest on its handle bar.
Place a heavy object (10kg sand bag, etc.) across the upper
part of the handle bar or tie down for additional security.
Take note how the grinding blocks and wedges have been
assembled, using a suitable wooden drift, knock out the
grinding block, not the wooden wedge. Dispose of the used
grinding blocks according to local legislation.
Fit each new grinding block squarely into the grinding plate
location corner at the outer at face of the grinding disc.
Secure with a new wooden wedge, between the block and
the inner face of the grinding block, knock the wedge into
position using a suitable drift.
Note:
Do not use a mix of old and new grinding blocks, this will
cause rapid wear of the new blocks and could cause the
machine to become uncontrollable, unstable and dangerous
in use. Re-adjust the lower guard and tighten the bolts.
Petrol/Gasoline Machines
Switch o the engine-powered versions and allow the engine
to cool completely, disconnect electric-motor-powered
versions from its power supply.
Place the machine on a at and level surface.
Raise the front skirt by loosening the four 10mm guard
retaining bolts on either side of the machine and slide the
guard up to the top of the slots, tighten the bolts temporarily.
It is not recommended that petrol/gasoline-powered
machines are tilted back such that they rest on their handles.
This may cause leakage of fuel and is therefore a hazardous
operation.
Remove the four countersunk M12 screws from the disc,
ensuring that the disc is supported as the last two are
removed. The disc now will come away from the drive plate.
Dispose of the used item according to local legislation.
Oer the new disc up to the drive plate and align the holes.
Loosely t the four bolts and then tighten in a diagonal
sequence to 40lb/ft. Re-adjust the lower guard and tighten
the bolts
Brush Seal Replacement
The machine is tted with a exible brush seal which will
need replacement from time to time to maintain the eciency
of the dust control system. Follow the rst ve steps from the
above procedure for changing discs. Drill out rivets and to
remove the brush simply grasp one end and pull, the brush
will come o the guard. To t the new brush, align one end of
the brush with the end of the guard and use a suitable drift to
knock the brush onto the metal guard, working along until it
is securely tted.

old blocks will cause oor damage and or rapid wear on the
new blocks.

rapid block wear check the hardness / coarseness of the
blocks v’s target oor surface.
3. Keep the machine moving at all times during operation for
the best results.
