Additional safety rules for radial arm saws
• Protect the electric power supply with a suitable fuse or circuit breaker.
• Keep the bearing tracks in the arm and the bearings on the roller head
assembly clean and free from grease.
• Before switching ON, make sure that the fence is in the correct
position. The blade should not contact the material until the saw is
pulled by the handle.
• Always set the finger guard so that it passes through the pre-cut slot in
the fence and/or 3 mm above the surface of the material being cut
(except when ripping).
• When ripping, keep the riving knife adjusted to the correct distance
from the blade (1 - 3 mm) and make sure the kickback fingers are
properly adjusted.
• When ripping, always check the direction of feed.
• Regularly check the adjustments for accuracy and adjust as required.
• Make sure that the blade rotates in the correct direction and that the
teeth are pointing towards the fence.
• Make sure all clamp handles are tight before starting operation.
• Never run the machine without all guards in place.
• When not in use, protect the saw blade completely using the blade guard.
• When not in use, when changing blades or carrying out maintenance,
disconnect the machine from the power supply.
• Always use sharp blades of the correct type designed for the workpiece.
The recommended blade diameter is stated in the technical data.
• Do not wedge anything against the motor fan to hold the motor shaft.
• Do not force the cutting action. (Stalling or partial stalling of the motor
can cause major damage. Allow the motor to reach full speed before
cutting.)
• Do not lift the machine by its worktable.
• Do not cut ferrous metals, non-ferrous metals or masonry.
• Do not apply lubricants to the blade when it is running.
• Do not place either hand in the blade area when the saw is connected
to the power source.
• Do not reach around behind the saw blade when in use.
• Do not place hands closer than 150 mm from the saw blade while cutting.
• Do not use damaged or cracked saw blades.

Ripping can be done with the motor in two positions. Each mode requires
its own direction of feed:
Position Direction of feed
- In-rip from right to left (fig. G1)
- Out-rip from left to right (fig. G2)
The pointer (71) indicating the ripping width on the rip scale (72) is
adjustable (fig. G3):
• Place the fence in rearmost position.
• Place a board of 24 mm against the fence.
• Unlock the yoke clamp lever (49), press the yoke latch (50) (fig. H1) and
position the motor in out-rip position (fig. G1).
• Move the yoke assembly along the radial arm until the blade just
touches the edge of the material.

ENGLISH
• Loosen the two screws (73) and move the pointer (71) until the edge of
the out-rip pointer (74) lines up with the known width of the board on
the lower scale (fig. G3).
• Tighten the two screws (73) (fig. G3).
• Place the motor in in-rip position.
• Raise the guard to allow the blade to rest against the face of the fence.
• The in-rip pointer (75) should now line up with the zero position in the
upper scale. Adjust if necessary (fig. G3).
Bevel scale (fig. G4)
• Check that the bevel scale (20) reads 0° when positioned for a vertical cut.
• If required, loosen the screws (47) and adjust the pointer to 0°.
Mitre scale (fig. G5)
• Check that the mitre scale (76) reads 0° when positioned for a vertical cut.
• Adjust the pointer (77) to register 0° using the screw (78).
The mitre scale has preset positions at 45° left and right and at 0°.
Yoke travel stop (fig. A2, H1 & H2)
The yoke travel stop (14) must be adjusted to avoid that the bearings on
the yoke assembly hit the rear limit of the bearing tracks (fig. A2).
• Push the yoke assembly as far as it will go, pull it forwards approx. 5 mm
and lock it the using the riplock (15) (fig. A2).

Switching ON and OFF (fig. A1)
The ON/OFF-switch of your radial arm saw offers multiple advantages:
- no-volt release function: should the power be shut OFF for some
reason, the switch has to be deliberately reactivated.
- motor overload protection device: in case of motor overload, the power
supply to the motor will be cut OFF.
• I = ON The tool now works in continuous operation.
• O = OFF
Making a trial cut (fig. A1)
• With the mitre latch lever (9) engaged, lock the mitre clamp lever (10)
so that the blade is positioned for a straight 0° cross-cut.
• Release the riplock (15) and push the yoke assembly back until the
blade is behind the fence.
• Lower the arm until the blade almost touches the table top.
• Place the workpiece against the front of the fence.
• Switch ON and lower the arm to allow the blade to cut a shallow
groove in the table surface.
• Pull the blade towards you so that it cuts a vertical slot in the wooden
fence and through the workpiece.
• Return the blade back to rest position and switch OFF.
• Check that the cut is a true 90° in all planes and adjust if required.
