safety regulations listed or applicable
to the job site.
This machine is primarily designed
for the smoothing of concrete,
marble and terrazzo surfaces. It can
be used both indoors and out.
Electric models are more suitable for
indoor use because of the toxic
exhaust gases that are produced by
petrol engines.
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 WORK PLACE
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. I t we ighs b etween
(92kg/202lbs) and (144kg /317 lbs)

Do not lift this machine manually.
Risk of Hand-arm
Vibration injury
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
p r o t e c t i v e e q u i p m e n t [ P P E ]
particularly gloves and clothing to
keep them warm and dry.
Employers should consider setting
up a programme of health
s u r ve i l l an c e t o e s t a b l is h a
benchmark for each operator and to
detect early symptoms of vibration
injury.
We are not aware of any PPE that
provides protection against vibration
injury by attenuating vibration
emissions.
See „Specifications‟ 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.
Media Types &
Applications
Grinding Blocks
All can be used wet or dry
Coarse grinding blocks
These are fitted as standard on
machines fitted with the grinding
block option. These are designed for
the rapid removal of material. They
produce a surface finish suitable for
directly laying floor coverings or for
two part epoxy paint coatings and for
the first grind of terrazzo floor
surfaces.
Medium grinding blocks
These are less aggressive than the
coarse blocks, they should provide a
surface finish 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 final finishing
to provide a surface suitable for final
polishing.

OPERATION
In addition, scarifying blocks and
wire brushes are available which can
be fitted in place of the grinding
blocks.
Diamond Disc machine
The machine is fitted with a 20
segment diamond disc for medium
concrete as standard (see below for
specification). There are also 10
segment discs for very aggressive
grinding and 16 segment discs for
aggressive grinding available. The
20 segment disc are the most
economical and least aggressive.
All discs can be used wet or dry.
Grinding disc 20 segment (Blue)
(Soft bonded diamond)
Premium disc.
For medium to hard material,
granite, cured concrete or terrazzo.
Grinding disc 20 segment (Black)
(Medium bonded diamond)
Premium disc.
For medium or general abrasive
materials - medium strength
concrete or adhesives.
Grinding disc 20 segment (Red)
(Hard bonded diamond)
Premium disc.
For softer or abrasive materials -
green (less than 48hrs old) or
medium strength concrete, or
adhesives.
Pre-Start Check
ALL VERSIONS
Check all bolts and screws for
tightness. Ensure that all fittings 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
a n d s e t a c c o r d i n g t o t h e
manufactures specifications.
In the event of malfunction on a new
machine, the owner should first
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 fitted 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, depress the red stop
button to reset.
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. To avoid
voltage drop the cable must be a
minimum core wire size of 2.5mm2
but preferably 4.0mm2cross-section.
The maximum length of cable can
then be 15 metres and 30 meters
respectively.
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 different
methods of rating their equipment.
All transformers and cables should
be fitted 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 30 meters.
Starting
Machines fitted with petrol
engines
The disc must be raised off the floor
surface before starting the engine
from cold.
The machine is fitted with a pedal
operated stand to allow the disc to
be raised off the ground when
starting the engine.
Tilt the machine back by it‟s handle
bar whilst depressing the pedal,
keeping the pedal depressed, lower
the machine back to the floor. The
weight of the machine keeps the
stand engaged and the head off the
floor.
The engine may now be started.
When starting from cold the throttle
lever must be in the fast position to
allow the automatic choke to
operate. Subsequent starting may
be carried out with the lever in the
idle/slow position.
Once the engine is at operating
temperature you may begin work.
To retract the stand simply tilt the
machine back.
See next section for detailed engine
starting procedure.
ENGINE VERSIONS
CAUTION
Beware of POISONOUS FUMES.
Start and operate only in well-
ventilated areas.
Be careful with
HOT COMPONENTS.
The exhaust and other engine parts are
hot during and for some time after
operation. Do not touch them.

OPERATION
Petrol engine starting procedure
Check that there is sufficient fuel in
the fuel tank. (See manufactures
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.
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.
Machines fitted with an
electric motor
IMPORTANT:
Pull back on the handle bars to
retract the machines stand, pull the
„hold to run‟ lever against the handle
bar and press the green start button
on the switch box, then gently lower
the disc onto the surface being
worked.
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 off
the ignition switch on Honda
engine versions.
Machine Operation
(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 filtered 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.
Shut Down
On electric powered machines,
simply release the “hold to run”
lever.
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 off from high
engine revolutions.)
Release the „hold to run‟ lever and
on Honda engines, switch off the
engine's start switch.
Important:
Close the engine fuel tap.
On both electric and engine powered
machines, use the stand to raise the
disc off 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 it‟s stand.
After the engine or motor has
completely cooled, clean off 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.
Machine Storage
Long period storage: over
3months
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.
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 finish 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 finish produced.
If necessary change the grade of
grinding blocks or diamond discs
and recheck performance and
surface finish.

MAINTENANCE
Belt Installation &
Adjustment
Removal
Remove t he top cover b y
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 off the
drive pulley and then remove it from
the engine/motor pulley.
Installation
Slide the new belt onto the engine/
motor pulley first, locating the belt in
the pulleys teeth. Then slide onto
into the teeth of the drive pulley.
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.
Tighten all engine/motor mounting
plate bolts fully, refit the top cover
and tighten the 8mm bolts.
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.
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.
Grinding Block
Replacement
Switch off 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 flat 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.
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 flat 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, unstab le a nd
dangerous in use.
Re-adjust the lower guard and
tighten the bolts.
Diamond Disc/Q.R.
Plate Replacement
Switch off 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 flat 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.
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 rope down for
additional security.
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.
Offer the new disc up to the drive
plate and align the holes. Loosely fit
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 fitted with a flexible
brush seal which will need
replacement from time to time to
maintain the efficiency of the dust
control system. Follow the first five
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 off
the guard.
To fit 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 fitted.
