4. E HAZARDS EXCESSIVE NOISE can lead to temporary or permanent loss of hearing WEAR an approved hearing protection device to limit noise exposure As required by Occupational Health and Safety regulations PROTECTIVE CLOTHING ALWAYS wear protective clothing and footwear to prevent the skin coming into contact with wet concrete PROTECTIVE FOOTWARE should be worn to reduce injuries from penetration through the sole contact with cutting objects slipping contact with wet concrete and electrical hazards GOGGLES for eye protection may also be necessary USE waterproof protection for hands and knees if kneeling when concreting If your clothing becomes wet from concrete contact make sure you change the clothing Do not walk about waiting for it to dry ADDITIONAL HAZARDS Slip Trip Fall is a major cause of serious injury or death Beware of uneven or slippery work surfaces OPERATION USING THE VIBRATING BEAM SCREED The effectiveness of vibration and hence degree of compaction increases with an increase of the beam weight the amplitude and the frequency and decreases with an increase in forward speed Forward speed is critical in the correct use of vibrating beam screeds and should be limited to between 0 5 and 1 0 m per minute Generally speaking the screed will have a self propelling motion resulting from its vibratory action It should be positioned on the slab so that its natural direction of travel is away from th
5. d TROUBLESHOOTING SYMPTOM POSSIBLE CAUSES AND CORRECTION Motor will not start Motor stops Electric Motor lacks power Check the ON OFF switch to ensure that it is switched ON Check the power supply and fuse or circuit breaker Thermal overload has tripped single phase only switch the power supply OFF and reset the thermal overload after the motor has cooled Check the power supply and fuse or circuit breaker Check the local power supply for voltage drop Use a shorter or a heavy duty extension lead Insufficient vibration Check for a slipping or a missing vee belt AN parchem Parchem Construction Supplies Pty Ltd 7 Lucca Road Wyong NSW 2259 Phone 1300 737 787 www parchem com au ABN 80 069 961 968 February 2012
6. e finished area The drag ropes and handles at the end of the beams should be used to control the direction and to supplement the self propelling motion of the screed beams Once the concrete with its surcharge has been spread start the motor and manually pull the beam along the slab Make sure that there is always a continuous surcharge along the entire length of the leading edge and that the ends of the beam ride on the edge forms Generally one steady pass with a double vibrating beam should be enough to compact and level the concrete However stiff mixes may require a second pass Extra passes might bring laitance to the surface Before using the motor after an electrical repair or if using a three phase reversible motor check the direction of rotation as shown by the direction arrow on the blade guard A 240 volt single phase electric motor can run in reverse due to incorrect internal connection of the motor winding when repaired When an extension lead is used select the shortest length and heaviest conductor size available to minimise voltage drop and prevent motor burn out Start the electric motor by turning the on off switch mounted on the motor to ON ALWAYS maintain good footing so that you do not slip and loose control when starting or operating the machine CARE AND PREVENTIVE MAINTENANCE Check the vibrator oil level weekly Inspect the rubber anti vibration mounts for wear or deterioration Clean
7. important items individuals should look for and obey Caution Warning and Danger signs placed on equipment and displayed in the workplace Operators should read and follow safety instructions packed vvth each product Learn how each machine works Even if you have previously used similar machines carefully check out each machine before you use it Get the feel of it and know its capabilities limitations potential hazards how it operates and how it stops APPLICATIONS Compaction of concrete slabs Aquaducts Precast sections Airport aprons Roadways Warehouse floors Light rail tracks Spillways Bridge decks FUNCTION AND CONTROLS POWER SUPPLY Electrical power is controlled by an on off switch which is mounted on the motor A thermal overload protection device is fitted to the single phase motor It is located below the switch If the motor stops switch the machine OFF determine the cause of the problem allow the motor to cool then press the reset button If the motor fails to start check the power supply fuses or circuit breaker and leads DRIVE BELT Tension of the drive belt is factory set by three plain washers which are fitted between the motor and the frame on each bolt PRE TENSIONED BEAMS Applicable only for units fitted with pre tensioned beams Adjust the Cable tension to factory setting by placing a steel ruler against the nut fitted to the threaded end of Cable and rotating the nut cloc
