SAFETY INSTRUCTIONS FOR TABLE SAWS
Warnings related to the use of guards
Keep the guards in their position. The guards should be operational and properly installed. A guard that is loose, damaged
or not functioning properly should be repaired or replaced.
Always use a circular saw guard and splitting wedge for each complete cutting operation. In case of complete cutting
operation where the circular saw completely cuts the workpiece thickness, the guard and other safety devices help reduce the
risk of injury.
Immediately reinstall the guards' system after completing the operations (such as notching, milling, or sawing off ) re-
quiring disassembly of guards and splitting wedge. The guard and splitting wedge help reduce the risk of injury.
Make sure that the circular saw does not come into contact with the guard, splitting wedge, or workpiece before switch-
ing it on. Unintentional contact of the devices mentioned above with the circular saw could cause an emergency.
Position the splitting wedge according to this instructions manual. Incorrect distance, positioning, and alignment may cause
the splitting wedge to be ineff ective in reducing rejection likelihood.
The splitting wedge should be coupled with the workpiece to work correctly. When cutting workpieces that are too short
to couple with the splitting wedge, the splitting wedge will be ineff ective. In such conditions, the splitting wedge cannot prevent
rejection.
Use a circular saw suitable for the splitting wedge. For the splitting wedge to function appropriately, the circular saw diameter
should correspond to the splitting wedge. The circular saw body should be thinner than the thickness of the splitting wedge, and
the cutting width of the circular saw should be wider than the thickness of the splitting wedge.
Warnings concerning cutting procedures
DANGER! Never put fi ngers or hands near or in the line of the circular saw. A moment's distraction or slipping could point the
hand towards the circular saw and cause serious bodily injuries.
Feed the workpiece to the circular saw only in the opposite direction to its rotation direction. Feeding the workpiece in
the same direction as that of the circular saw rotation above the table might cause the workpiece and hand to be pulled into the
circular saw.
Never use a bevel indicator to feed the workpiece when performing longitudinal cutting. Do not use a guide for longitu-
dinal cutting as the length stop for transverse cutting with bevel indicator. Guiding the workpiece using the guide for longi-
tudinal cutting and bevel indicator at the same time increases the likelihood of the circular saw becoming entrapped and rejection.
When performing longitudinal cutting, always apply the workpiece feed force between the guide and the circular saw. Use
the pusher when the distance between the guide and the circular saw is shorter than 150 mm and use the pressure holder
when this distance is shorter than 50 mm. Ancillary equipment will keep the hand in a safe distance from the circular saw.
Use only the pusher supplied by the manufacturer or constructed according to instructions. Such a pusher ensures an
adequate distance of the hand from the circular saw.
Never use a damaged or notched pusher. A damaged pusher may break, causing the hand to slide into the circular saw.
Do not perform any operation "manually". Always use the guide for longitudinal cutting or bevel indicator to position or
guide the workpiece. "Manually" means using hands to support or guide the workpiece instead of using the guide for longitudinal
cutting or bevel indicator. Manual trimming leads to misalignment, circular saw entrapment, and rejection.
Never reach over an operating circular saw or around it. Reaching for the workpiece may result in accidental contact with the
rotating circular saw.
To keep long or wide workpieces in a horizontal position, provide support for the piece from the table's back or sides.
Long or wide workpieces tend to rotate on the table edge, which results in control loss, circular saw entrapment, and rejection.
Feed the workpiece at an even rate. Do not bend or twist the workpiece. In case of jam, immediately switch off the tool,
disconnect it from the mains, and remove the jamming object. The circular saw jamming by the workpiece may cause rejec-
tion or the motor to stop.
Do not remove pieces of cut material while the circular saw is rotating. The material can be trapped between the guide or
inside the circular saw guard. The circular saw may pull the fi ngers inside. Before removing the material, switch off the saw and
wait for the circular saw to stop.
Use an auxiliary guide in contact with tabletop to cut the workpieces
with a thickness of less than 2 mm. A thin workpiece can get stuck under the guide for longitudinal cutting and cause rejection.
Reasons for rejection and related warnings
Rejection is a sudden reaction of the workpiece due to a clamped, jammed circular saw, or misalignment of the workpiece cutting
line in relation to the circular saw or when a part of the workpiece is entrapped between the circular saw and the guide for longi-
tudinal cutting or another fi xed object.
During rejection, the workpiece is often lifted from the table by the back part of the circular saw and directed towards the operator.
The rejection results from misuse of the saw or misconduct during work or improper working conditions, and it can be avoided by
taking appropriate precautions which are presented below.
Never stand directly in the line with the circular saw. Always stand on the circular saw side where the guide is located.
Rejection can drive the workpiece at high speed towards anyone who stands in front of the circular saw and in line with it.
