Figure 2 Assembly of a table circular sawing machine 1 stand, 2 receding table, 3 stop for cross and angle cuts, 4 splitting wedge, 5 guard hood, 6 saw blade, 7 machine table, 8 stop rule
The stand bears the machine table and movable receding table and also houses the height-adjustable motor.
The machine table is directly attached to the stand and serves to direct the workpieces to the saw blade.
A stop rule which is adjustable and parallel to the saw blade is on the machine table - to the right of the saw blade. This stop rule serves to set the width of oblong cut workpieces.
This is positioned in a movable manner vis-a-vis the stand and serves to undertake cross and angular cuts whose angle setting can ensue by means of a stop.
Motor, motor shaft and saw blade
Motor and motor shaft can be adjusted up to an angle of 45° by means of hand wheels. The saw blade is attached to the saw shaft by means of two flanges and a chucking nut.

The table edges close to the saw blade and the machinable material are interchangeable.
The distance between saw blade and table edges must not be greater than 3 mm in order to prevent the drawing in of narrow wood pans!
Splitting wedge and guard hood are protective devices of the circular sawing machine. The machine shall not be used without these protective facilities, otherwise considerable accident risk!
The splitting wedge is adjustable and aligned to the curve of the saw blade whereby the distance from saw blade shall not exceed 10 mm!
Figure 4 Required protective distances 1 machine table, 2 splitting wedge, 3 guard hood, 4 workpiece, 5 saw blade
The splitting wedge is safeguarded from slipping, adjusting or moving upwards and shall keep apart the separated workpieces thereby ruling out upward and backward sliding of the workpiece. The guard hood is attached to the splitting wedge and consists of machinable material. The saw blade is thus covered up from above. Chips arising are deflected through an escape slot.
The guard hood must protrude 20 mm above the cutting circle of the saw blade feed in the machine table!
Distance of guard hood to workpiece surface shall not exceed 8 mm in rest position!
During the cutting operation the guard hood shall only expose the saw blade section required for cutting. After the cutting operation is over the saw blade must be completely concealed.
If these hints are not observed serious accidents may result!
