OPERATION

General Information

Thank you for your purchase of the Multiheaded Scabbler.

Before operating the Multi-headed Scabbler, 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 Scaler 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 or applicable to the job site.

The tool is primarily designed for concrete reduction, and the removal of laitance from concrete floors, but may also be used for the removal of paint or epoxy floor coatings, it can be used both indoors and out.

This machine must not be used in a fixture.

Note:

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 fill or finish 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 leaving a relatively flat surface, these are also suitable for the removal of paint and epoxy coatings.

Operators should be familiar with the data given in the specification section.

Please keep these instructions in a safe and accessible place.

This tool must not be used in potentially explosive atmospheres.

Where a vacuum shroud assembly is supplied separately, see the instructions under

“Servicing” for fitting.

Manual Handling

The complete tool weighs approximately 70kg

(155lbs).

Where possible use a hoist with correctly rated lifting equipment to connect to the supplied lifting eyebolt fitted on the top of the

MHS11 Scabbler.

Ensure that the eyebolt is screwed down to its shoulder and has been tightened using a bar no longer than 150mm (6.00”).

Always ensure the handle is locked and secure during any handling operation.

Always apply local health and safety regulations with regard to manual handling.

Safety Precautions

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.

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.

Please note: Unrestrained hoses can whip if they become detached.

Ensure that the work place is well ventilated.

Avoid operating engine-powered compressors in an enclosed area, since engine exhaust gases are poisonous.

Recommended lubricants

Oil the tool daily before use. Put a liberal quantity of one of the following air tool lubricants through the air inlet.

SHELL

CASTROL

Naturelle HF

Carelube HTG 22

Cleaning

At intervals of no more than 100 hours use, or if operation becomes unproductive, or if any of the pistons 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 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 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.

Pre-Start Check

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 o 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 33L/s (70cfm) free air. In particularly cold weather it is recommended that a proprietary anti-freeze lubricating oil be used.

Starting Work

Prior to operating the tool check: -

That all fittings are secure, free from leaks and air hoses are in good condition.

That all parts of the tool are fully screwed together and secure, if in any doubt ask your supervisor before using this equipment.

That a liberal amount of lubricant has been put into the air inlet of the tool. (See recommended lubricants)

Safe use of this tool requires a solid stance and secure foothold; the operator must adopt a firm and stable position at all times. Depress the foot mechanism (24) to release the handle. Never run the tool with the handle fastened to the main body. To operate the tool turn the ball valve on the handle to the fully opened position and immediately start to move the tool back and forth, continue until the desired finish is achieved. Never run the tool continuously in the same place, as the cutterheads will dig into the surface. If the tool is new, optimum performance will be achieved after 15mins “running in” of the brush seals

(48). To switch off, simply return the ball valve lever to 90° to the handle whilst continuing to move the tool back and forth, return handle to the upright position, ensuring foot release has engaged. Complete a small area noting the performance; stop the machine, inspect the finish produced. Handled correctly the MHS11 Multi-headed Scabbler will work quickly and efficiently.

Gloves and personal protective equipment

must be worn when using this tool. The tool will ride irregularities of up to 13mm (1/2”).

Anything greater will risk cutterhead damage.

Care must be taken to avoid damaging or tripping over the air hose.

Servicing

Only a competent person, in a suitably equipped workshop, must carry out maintenance.

Disconnect the tool from the air supply before carrying out any of the following operations.

Dismantling

After ensuring that the air supply is turned off, remove the tool from the airline. Thoroughly clean the outside of the tool prior to dismantling.
