width of cut.
Blade Sharpness Dull and worn blades exert more force
on the timber thus creating more noise.
Balance Out of balance blades mean vibration
and changes in cutting conditions,
resulting in increased noise levels.
Extraction
Air Velocity/ System Design
Resonant conditions can lead to high
noise levels, excessive turbulence and
chip impact can increase noise levels
substantially
The figures quoted are emission levels and are not necessarily safe working levels. Whilst there
is a correlation between the emission and exposure levels, this cannot be used reliably to
determine whether further precautions are required. Factors that influence the actual level
of exposure of the workforce include the characteristics of the work room and the other
sources of noise, etc., i.e., the number of machines and other adjacent processes. Also, the
permissible exposure level can vary from country to country. This information, however, will
enable the user of the machine to make a better evaluation of the hazard and risk.
10.0 Maintenance Instructions
10.1 Cleaning and Lubrication
To ensure long life, maximum reliability and optimum performance, the following monthly
maintenance and lubrication schedule should be carried out, otherwise the machines
warranty could be invalidated.
Improper maintenance can cause serious injury or damage. For this reason it should only be
carried out by authorised, trained personnel who are familiar with how to operate the
machine and in strict observance of all safety instructions.
Work on electrical fittings may only be carried out by qualified personnel and in strict
observance of the safety instructions.
Note. Electrically isolate the machine and ensure that all spindle movement has ceased
before carrying out any of the operations.
Keep the table clean and protected. Coating the cast iron with beeswax will reduce friction
between the table and workpiece and inhibit corrosion. Avoid products that contain
silicone, anti-slip additives, or abrasives. Avoid contact with anything moist. Do not set drinks
on the tabletop or leave green wood on it. These will leave permanent marks. Any surface
rust can be removed with auto rubbing compound and a wool bonnet. Work slowly and
carefully; use the rubbing compound liberally. If the saw is to be stored for any length of time,
lightly oil any surface that may rust before storing. The oil can be removed later with mineral
spirits or other solvent.
Always check that the table rings are correctly seated on the keeper plates when carrying
out maintenance, or when tool changing. The rings should sit level with the tabletop without
any rock in them. Too high at the front and timber will catch on the front edge of the rings
before entering the blade, too low and timber is in danger of catching on the inside lip of the
table and being kicked back by the cutters. The underside of the table has been precision
machined, negating the need for adjusting screws. Should the rings not sit properly after a
thorough clean they may have been damaged and should be replaced.
