Trelawny LPS55, Operation And Maintenance Manual

Page: 4 / 8

OPERATION
Foreword
Thank you for purchasing the LPS 55.
This manual contains the necessary
maintenance information for you to ensure
proper operation and care for your machine.
It is essential for you to read through these
manuals thoroughly.
In the unlikely event that you experience
problems with your LPS 55, please do not
hesitate to contact your local dealer or agent.
We always welcome feedback and comments
from our valued customers.
General Information
Before operating the LPS 55 Scabbler/
Tamper, this manual must be read and
understood by the operator, if in any doubt
ask your supervisor before using this
equipment. Failure to follow these instructions
could result in damage to the LPS 55
Scabbler / Tamper and/or personal injury.
Trelawny SPT Ltd disclaims all responsibility
for damage to persons or objects arising as a
consequence of incorrect handling of the tool,
failure to inspect the tool prior to starting work
for damage, or other faults that may influence
the operation or safe working of the tool, or
failure to follow the safety regulations listed or
applicable to the job site.
The tool is primarily designed for concrete
reduction and for the removal of laitance from
concrete.
The LPS 55 is also available as a Tamper and
can subsequently be fitted with a Tamper
head for the compaction of soil, tarmac or
aggregate.
This tool must not be used in a fixture.
A VL LRS 55 is also available as a vibration
reduced Compactor or Scabbler version.
All versions can be used both indoors and out.
Safety
Always, read through these instructions first
before use.
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 and dry. 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 ‘ Specifications ’ section for vibration
emission data.
Further advice is available from our Technical
Department.
Starting Work
Prior to operating the tool check: -
That all fittings are secure, free from air leaks
and that air hoses are in good condition.
That all parts of the tool are fully screwed
together and secure, if you are in any doubt
ask your supervisor before using this
equipment.
That the air pressure is correct for this tool
6.2 bar (90 psi.).
That a liberal amount of lubricant has been
put into the air inlet of the tool. (See
recommended lubricants)
Before operating the tool ensure that the tool
is not near your chin or face.
Safe use of this tool requires a solid stance
and secure foothold; the operator must adopt
a firm and stable position at all times.
On start up, the tool will rise two to three
inches (75mm).
To operate the tool pull the lever towards the
handle grip.
Let the tool do the work; allow a period of time
to become accustomed to the tool. The tool
does not require any down force to operate;
excessive pressure will prevent the tool from
working effectively. Maintain contact with the
work surface with sufficient pressure only to
keep the tool under control.
Bush Hammer style headed pistons are best
suited to concrete reduction and for laitance
removal; these may reduce the likelihood of
damage to the aggregate, ensuring that a
stronger bond is created with the next layer.
Cruciform headed pistons are suited to the
reduction of concrete or where a smoother
finish is required; these will reduce the
aggregate as well as the concrete surface.
To switch off, simply release the throttle
lever.
Do not press down on the tool, excessive
pressure will prevent the tool from working to
its full capacity and will increase the vibration
emissions.
IMPORTANT
Before operating this equipment, the
operator should read this manual.
Whenever possible, he/she should be
trained how to operate the machine by an
experienced person.
Trial and error is not the safe way to
become familiar with this piece of
equipment.
Always observe safe working practices
and local safety regulations at all times.
Do not allow the tool to run unattended.
Do not allow the tool to run continuously
whilst not in contact with the surface being
prepared.
Do not modify this tool in any way, as
this will invalidate the warranty and could
lead to serious injury.
Do not use this tool in potentially
explosive environments.
Do not drag this tool by the air hose.
Do not use petrol (gasoline), thinners or
any other high flash point solvent to clean
the tool.
Air Supply
The compressed air supply must be free
from water and dirt. The installation of a
filter/regulator/lubricator air preparation set
(with moisture trap) adjacent to the tool is
strongly recommended.
Always clear the air hose before connection
to the tool. Ensure that no moisture
(condensation) is present in the air hose.
Ensure that a minimum 19mm (3/4”) bore
air hose is used and that all couplings are
secure; leak free and in good condition.
Limit the length of air hose to 15M (50ft).
Where extra length is necessary, for each
additional 15M (50ft) of air hose used, the
pressure drop is approximately 0.16bar
(3psi).
Correct operating pressure is 6.2bar (90
psi).
Do not let the operating pressure fall below
5.5bar (80p.s.i.) or rise above 6.9bar (100
psi) absolute maximum.
Preferably, the compressor should be able
to supply a minimum of 18.9 L/s (40cfm)
free air.
In particularly cold weather it is
recommended that a proprietary anti-freeze
lubricating oil be used.
Recommended Lubricants
Oil the tool daily before use. Put a liberal
quantity of one of the following zinc free air
tool lubricants through the air inlet. It is
recommended that an inline lubricator be
installed in the air hose adjacent to the tool.
SHELL Naturelle HF
CASTROL Carelube HTG 22
Cleaning
At intervals of no more than 100 hours use,
or if operation becomes unproductive, or if
the piston shows signs of sticking,
dismantle and clean with highly refined
paraffin. Replace any worn components as
necessary.
Immediately after cleaning, thoroughly oil
the tool with one of the recommended
lubricants.
Risk of Hand-Arm
Vibration Injury
These tools may cause Hand-arm Vibration
Syndrome injury if their use is not
managed.
Do wear Personal Protective Equipment
including safety goggles, footwear, ear
defenders and gloves.
In some environments it will be necessary to
wear facemasks or breathing apparatus.
Do be aware that this tool is not
electrically insulated.
Do ensure that this tool is lubricated daily .
Do be aware that this tool can create dust
and flying debris.
Do be aware of others working around
you.
Do keep hands and clothing away from
moving parts.
Do store this tool in a secure and dry
environment.
