the root of the teeth, irrespective of the position of the saw unit. When the flange / clamping nut is not
circular, it shall be covered by a fixed guard. The top guard of bench saw mode shall be lockable in the
mitre saw mode, or the bench saw table shall completely protect the saw blade when the top table is
adjusted in the highest position (type “A” saw).
In the upper position, the machine shall have a combination of fixed and self-closing guards which guard
the area 2. These guards shall, as a minimum, cover the periphery of the saw blade within the area 2 and
both sides of the saw blade within area 2 at least down to the root of the teeth. See Figure Z104 for
illustration.
The guard shall comply with this requirement at any mitre and bevel position which is possible.
The self-closing saw guard shall comply with either a) or b):
a) The guard shall be of a U-shaped construction (see Figure Z101 a)). The guard shall enclose the
teeth of the saw blade.
For saws with linked action and with the saw unit in its upper position, the guard shall be in its
completely closed position and both the guard and saw unit shall be locked.
Compliance is checked by inspection and the following test.
The saw unit in the upper position at 90° to the table is subjected to a load of 100 N vertically
downwards at the highest point of the operating handle. It shall not be possible to touch the teeth of
the saw blade with the test probe of Figure Z108, taking into account any free movement of the
guard.
The saws unit and guard shall only be unlocked by manually operating the release device(s) and the
guard shall open by moving the saw unit down. It shall be possible to operate the release device(s)
without releasing the grip on the handle.
Compliance is checked by inspection and by manual test.
For saw units without linked action and with the saw unit in its upper position, the guard shall be
locked. When moving down the saw unit from its upper position, the guard shall remain locked and
closed in all positions of the saw unit and only be unlocked and opened by manually operating the
release device.
Compliance is checked by inspection and by applying the test probe of Figure Z108 in all positions of
the saw unit. It shall not be possible to touch the teeth of the saw blade taking into account any free
movement of the guard.
After manually operating the release device, the guard shall open by further pressing of the release
device for an angle of maximum 60°.
Compliance is checked by inspection and by manual test.
b) The guard shall be of an open guard construction (see Figure Z101 b)) which covers both sides of
the saw blade teeth as shown in Figure Z106 and which opens when it makes contact with the
workpiece or the fence. The guard shall lie on the workpiece or on the fence during cutting to afford
maximum protection.
Compliance is checked by inspection and by manual test.
The guard shall be in its completely closed position and locked when the saw unit is in its upper
position.
Compliance is checked by inspection and the following test.
The saw unit in the upper position at 90° to the table is subjected to a load of 100 N vertically
downwards at the highest point of the operating handle. The guard shall remain locked and not open.
It shall be possible for an operator to unlock the guard without releasing the grip on the handle.
Compliance is checked by manual test.
– 13 – EN 61029-2-11:2012
18.1.101.2 In cutting mode, the front of the saw blade shall be guarded against inadvertent contact.
Compliance is checked while the saw unit is at its lowest vertical position, its maximum extended
horizontal position and no workpiece present. A test rod with 12 mm diameter and 50 mm length is applied
at all bevel and mitre angles. The longitudinal axis of the test probe shall be parallel to the table surface
and be perpendicular to the cutting line. The test probe shall be equally shared about the cutting line.
When the test probe is moved towards the saw blade, it shall not be able to touch its toothed rim.
18.1.101.Z1 For saws in mitre saw mode and without linked action provided with a spring loaded guard,
the closing time of the self-closing guard from the fully open position to the fully closed position shall not
exceed 0,3 s.
Compliance is checked by the following test. During the test, the saw unit is set to cut at 90° to the table.
Without any lubrication, the self-closing guard is retracted fully and then allowed to close for
20 000 cycles. The closing time from the fully open position to the fully closed position shall not exceed
the time specified above at the first and at the last of the 20 000 cycles.
18.1.101.Z2 All types of guard shall allow changing of the saw blade without removing the guard from
the machine.
Compliance is checked by inspection.
18.1.101.Z3 When set for transportation the self-closing guard shall cover the teeth of the saw blade to
the front of the machine.
Compliance is checked by inspection and by applying the test probe according to Figure Z108.
18.1.101.Z4 Saws shall be so guarded that the saw blade cannot be touched from below the table. For
type “B” saws, this requirement may be met by a removable guard without interlocking.
Compliance is checked by the following test.
For type “A” saws:
Below the mitre saw mode table and with the saw unit in its lowest position, the test probe of Figure Z108
is applied in all possible positions, it shall not be possible to touch the teeth of the saw blade. Above the
mitre saw mode table, the guarding shall still comply with the requirements of 18.1.101.1 and 18.1.101.2.
For type “B” saws:
With the saw unit in its lowest position the test probe of Figure Z108 is applied in all possible positions. It
shall not be possible to touch the teeth of the saw blade.
18.1.102 Bench saw mode
18.1.102.1 Combined mitre and bench saws shall have a top guard for the crown and the front of the
saw blade which may be an adjustable guard, a self closing guard or a combination of these and may be
removable. If adjustable, it shall be possible to do so without the aid of a tool and when adjusted, it shall
remain in any position necessary to give the required protection.
The top guard shall be constructed from soft material (e.g. aluminium or plastic) which will minimize
damage to the saw blade should contact occur.

18.1.103 Guarding below the table
18.1.103.Z1 Guarding below the bench table for Type “A” machines
Access to the toothed rim of the saw blade shall be prevented by either:
– being in accordance with the requirements of 18.1.101;
or
– with additional guarding which, if detachable, shall be interlocked either electrically or mechanically,
which prevents the tool operating in the bench saw mode position unless this guard is installed.
Compliance is checked by inspection and by applying the test probe of Figure Z108 in any possible
position.
18.1.103.Z2 Guarding below the table for Type “B” machines
When used as a circular saw bench, the saw unit shall be capable of being locked in this position.
Compliance is checked by inspection.
It shall not be possible to touch the toothed rim of the saw blade from the front and the rear.
Compliance is checked by applying the test probe of Figure Z108 in any possible position with the saw
unit set for 90° and maximum depth of cut. The test probe is not applied from the sides of the saw blade
over a section extending 25 mm below the lower surface of the table, see Figure Z112.
18.3 Replacement of the first two paragraphs:
In any working position, the machine shall have sufficient stability.
Compliance is checked by the tests in 18.3.Z101 and 18.3.Z102, without the saw being fixed to the bench.
18.3.Z101 Bench saw mode
The tool shall be placed on a horizontal fixed chipboard with smooth surface.
When a push force of 100 N is applied to the front edge of the saw table in the direction of the workpiece
feed, the tool shall not move or start to tip.
The force is then increased to 300 N or until the tool begins to move horizontally, whichever is achieved
first. During this test, the tool shall not tip over.
18.3.Z102 Mitre saw mode
The tool is set to its upper position with the saw blade in vertical position and at 0° mitre angle. Without
any workpiece, the saw unit is moved down to its lowest position, and then the handle is released. The
machine shall not tip over and shall not be displaced horizontally by more than 100 mm.
18.3.Z103 Tools shall be provided with the facility to fix the machine to a bench, e.g. by providing holes
in the machine frame.
