TFP260 FLOOR PLANER
OPERATION & MAINTENANCE

OPERATION
Foreword
Thank you for your purchase of the
TRELAWNY TFP260 Floor Planer.
This manual contains the necessary
maintenance information for you to ensure
proper operation and care for this machine.
See also the manual that is supplied by the
engine manufacturer.
It is essential for you to read through these
manuals thoroughly.
In the unlikely event that you experience
problems with your TFP260, please do not
hesitate to contact your local Trelawny dealer
or agent. We always welcome feedback and
comments from our valued customers.
General Information
Before operating, performing maintenance or
repairing the TFP260 FLOOR PLANER this
manual must be read and understood by the
operator, if in any doubt, ask your supervisor
before using this equipment.
Local safety regulations must be followed at
all times. Failure to follow these instructions
could result in damage to the TFP260 and/or
personal injury.
Trelawny SPT Limited disclaims all
responsibility for damage to persons or
objects arising as a consequence of incorrect
handling of the machine, failure to inspect the
machine for damage or other faults that may
influence the operation prior to starting work,
or failure to follow the safety regulations listed
or applicable to the job site.
This machine is primarily designed for the
removal of paint, heavy rust, scale and for the
removal of laitance from concrete from floor
areas. It can be used both indoors and out.
Electric models are more suitable for indoor
use because of the toxic gases that are
produced by petrol engines.
This machine must not be used in a fixture.
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. Exhausts 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 cock.
DO NOT OPERATE ELECTRIC VERSIONS
IN WET CONDITIONS.
CAUTION THIS MACHINE IS HEAVY. It
weighs around (Wt 122 kg (269 lbs))
dependent on power unit. Do not lift this
machine manually.
IMPORTANT:
When fitted with the petrol engine, AVOID
TIPPING THE TFP260 BACKWARDS,
especially when hot; the engine oil can run
past the piston and into the combustion
chamber causing the piston to “hydraulic lock”
when next attempting to start the engine.
Never attempt to forcibly turn the engine over
if this has taken place, severe damage to the
engine can be caused, resulting in a costly
major strip down and possible injury to the
operator.
To remove the oil from the cylinder, first
remove the spark plug and place a lint free
cloth over the plughole to capture the
jettisoned oil. Turn the engine over with the
ignition switch and fuel cock in the off position
and expel as much of the oil as possible.
Clean the spark plug to remove oil from the
electrodes and replace. The plug may have to
be removed and cleaned several times before
the engine will start. Upon starting, the engine
may produce smoke for a while from the
exhaust, but this should soon clear.
Finally stop the engine and recheck the
engine oil level. (Ensure that the engine is
level prior to carrying out this check). If the
engine oil level is low, refill with the
recommended motor oil - see engine
manufacturers operating instructions.
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
m a i n t a i n e d a c c o r d i n g t o o u r
recommendations, and ensuring that the
operators wear personal protective equipment
[PPE] particularly gloves and clothing to keep
them warm and dry.
Employers should consider setting up a
programme of health surveillance to establish
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 &
S a fe t y E x e c ut i v e w e bs i t e h t t p: //
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.
Cutter types &
Applications
T.C.T
Hardened steel cutter with tungsten carbide
inserts. For all general cleaning applications,
including concrete texturing, Scabbling, the
grooving of concrete, removal of embedded
roof chippings, brittle coatings from steel
work. Use TCT Cutters on heavy applications,
for longer life and higher output. Produces
“tramlines” on concrete and small indentations
on steelwork.
STAR
Heat-treated steel cutters used for the
aggressive removal of Paint and coatings
from floor areas, but with a shorter life span
than Beam Cutters. Can be used for the
general removal of dirt and ice deposits and to
produce a texture on concrete surfaces.
Produces roughened surface on concrete and
some marking on steelwork.
BEAM
Heat-treated steel cutters used for the
removal of Paint and coatings from floor
areas, but with a shorter life span that TCT
Cutters, not as aggressive as Star Cutters.
Can be used for the general removal of dirt
and ice deposits. Produces a fine texture on
concrete surfaces and slight marking on
steelwork.
MILLING
Flat tungsten carbide cutters for the removal
of thermo-plastic road and runway markings.
Very efficient and cost effective with none of
the problems associated with burning off.
These can also be used for the removal of
bituminous and rubber deposits. Very
effective for the removal of two part epoxy
floor paint, may require finishing with beam
cutters or the Trelawny floor grinder to
achieve the required finish.
Note: Care must be taken with milling cutters
to ensure that the Drum and its Cutters are is
fitted the correct way round, the tungsten
carbide tips must face towards the vacuum
port at the bottom as the drum rotates,
otherwise the tips will be damaged in use.
Produces a “strip” on concrete and tarmac, is
not recommended on steelwork unless used
for “braking up” coatings.
NB: Increasing or decreasing the number of
spacers used can alter the performance and
finish characteristics of each cutter type.
Ensure that the same type and quantity of
spacers and cutters are fitted to the opposite
cutter shaft to maintain the drums balance. An
out of balance drum can be very dangerous
and will also dramatically increase the
vibration emissions.

OPERATION
Open the engine fuel cock.
Set the throttle lever on the engine to
approximately a halfway open position.
For cold engine starting, move the carburettor
choke lever to the choke "full on" position.
Set the engine switch to the "on" position.
Where fitted, pull the Hold to run lever
towards the handle bar.
Pull the recoil starter cord handle.
After the engine starts, open the choke
approximately halfway, or until the engine
runs smoothly. Warm the engine up for 2~3
minutes at half engine speed before opening
the choke fully.
The warm up procedure is particularly
important during cold weather.
Electric models: Follow instructions in
Starting at paragraph three, then pull the Hold
to run lever towards the handle bar, press
start button on control box. Continue
instructions with item 2,3 and 4 in Machine
Operation below.
Machine Operation
Ensure that the depth of cut adjustment hand
wheel is in the fully raised position and the cut
engagement lever is up.
On Petrol engines set the throttle lever on the
engine to fully "open/run" position.
Continue holding the handle bar and dead
mans handle in the "on" position.
Place the cut engagement lever in the forward
engaged position and slowly rotating
clockwise the depth of cut hand wheel (55).
The cut engagement lever (58) will move
forward/down while adjustment is made, if it
does not, ensure that the cut engagement
lever has been pushed to the forward position.
Adjust the depth of cut hand wheel until the
cutters are in contact with the surface, slowly
adding more cut until sufficient material is
being removed. Be aware that several lighter
cuts is more efficient than one heavy cut.
Heavy cuts will only increase wear of drum
components and increase operator fatigue.
The Planer may move forward during the
cutting operation, due to the action of the
cutter drum. Control this by holding the handle
bar. When planing rough surfaces the
machine may jerk forwards if too heavy a cut
is made. Reduce the amount of cut by raising
the cutters via the cutting depth adjustment
hand wheel (55).
Pre-Start Check
Check all bolts and screws for tightness.
Ensure that all fittings are secure.
Check the drive belt for correct tightness.
There should normally be approximately
13mm (1/2") of free play when one side of the
belt is depressed in the middle position
between the two pulleys. To set the belt
tension, refer to the Belt installation & Setting
section.
For Petrol Engines
Check engine oil level. If the engine oil level is
low, refill with the relevant motor oil
recommended in the engine manufacturers
operating and maintenance manual.
IMPORTANT: Do not lean the machine
backwards onto its handle to inspect the
cutters or drum. It is possible for engine oil to
seep into the cylinder bore, especially if the
engine is hot. If this has occurred,
DO NOT ATTEMPT TO START THE
ENGINE,
the oil can cause the piston to lock
hydraulically, which may cause severe
damage to the engine and injure the operator.
With ignition turned off, very slowly pull the
starter cord, if the engine cannot be turned
over, the above may have taken place.
Rectification will necessitate the spark plug
being removed and the engine turned over by
pulling the starter cord (with ignition turned
off) to “eject” the oil. Use a lint free clean cloth
over the plughole to capture the ejected oil.
The spark plug will require removing and
cleaning, possibly several times until the
engine restarts.
415v Motors
The TFP260 is supplied with a specially
commissioned electric motor and starter
switch assembly. Each unit is fully tested and
the overload relays have been calibrated and
set according to the 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.
The starter boxes are preset and under no
circumstances should they be tampered with,
stripped down or adjusted, otherwise it will
invalidate the warranty.
Take particular care when using 415v
Machines; ensure that the electrical supply is
earthed and that breakers and fuses are
correct for the loading. The switches are
preset and under no circumstances should
they be tampered with, stripped down or
adjusted, otherwise it will invalidate the
warranty.
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.
IMPORTANT
Do not pull the recoil starter cord to the end
of is 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.
ENGINE VERSIONS
CAUTION
Beware of POISONOUS FUMES. Start and
operate only in well-ventilated areas.
Be careful with HOT COMPONENTS.
