The Dado head (fig. F1, N1 & N2)
There are two types of dado heads available. Figure N1 shows the
standard quality dado head and figure N2 shows the long life premium
quality model.
Sharp edges.
Mounting the dado head
• Remove the blade guard assembly and the blade.
• Mount the spacer (94) onto the arbor with the narrower side towards
the motor.
• Mount the cutter blades (95) with the required number of intermediate
blades (96A) between them together with a combination of shims (96)
to achieve the required width of cut.
• Secure the dado head using the standard arbor nut (45) (fig. F1).
• Remove the riving knife and its support bracket from the blade guard
assembly and mount the guard.
• Lower the dado head into position for the depth of cut required.
Using the dado head
- In crosscut or mitre position
• Adjust the anti-kickback fingers up and out of the way.
• Adjust the finger guard correctly.
- In ripping position
• Adjust the anti-kickback fingers correctly.
Disc sanding and drum sanding (fig. M2, O1 & O2)
Two sanding attachments are available for cuts requiring sanding at any
angle. Both can be used as follows:
- moving the workpiece along the stationary accessory
- moving the accessory along the clamped workpiece
• Remove the blade guard assembly and the blade.
• Return the outer flange (46) (fig. O1).
• Mount the disc sander (97) or the sanding drum (98) (fig. O2) directly
onto the arbor (39).
Disc sanding (fig. O1)
• Always use the downward (right-hand side) of the disc.
• When using the disc sander (97) for horizontal sanding, the shaping
head guard (94) (fig. M2) should be mounted and adjusted so that the
sanding disc is just clear of the underside of the guard.
Drum sanding (fig. O2)
• When drum sanding, always feed your material against the rotation of
the drum sander.
The router bracket (fig. F1, P1 - P3)
The router bracket (99) allows you to attach a Elu router (MOF96,
MOF131, MOF177 or OF97) to your machine, thus extending its versatility
to accurate, decorative woodworking (fig. P1).
Mounting the router bracket
• Remove the blade guard assembly and the blade.
• Position the router bracket (99) over the end of the arbor as shown in
figure P1 and secure it with the wing nut (63).
• Replace the guide rods of the parallel fence of your router by the
support bars (100) supplied with the attachment:
- Use the small diameter bars for MOF96 (fig. P2)
- Use the large diameter bars for MOF131/MOF177/OF97 (fig. P3).
• Tighten the locking screws (101).
Always make sure your router is properly centred on the bars
and secured in the bracket.

Routing
The router can be set to the required angle and pulled across the
workpiece using the handle (2) in figure A. Alternatively, guide the
workpiece along the stationary cutter.
• Check that the router bracket is mounted rigidly.
• If required, fit the outer flange (46) in figure F1 on the arbor and clamp
Drilling/boring (fig. Q)
The threaded location hole (102) accepts the optional 10 mm or 3/8" drill
chuck which turns your Saw into a versatile radial drilling unit. This option
is particularly useful for preparing material for dowels.
• Remove the blade guard assembly and the blade.
• Pivot away the cover (103).
• Fit the drill chuck (104) directly into the threaded location hole (102).
Mitre fences (fig. R1 & R2)
Mitre fences (105) are available to extend and speed up the angle cutting
facility (fig. R1).
• Replace the standard fence by the mitre fences (105).
• Guide the saw blade between the two fence sections (fig. R2).
Traverse control (fig. S1 - S3)
The traverse control (106) guarantees optimum results in applications
where a consistent, even feed rate is important.
Mounting the traverse control
• Remove the return spring (87) in figure K.
• Remove the yoke travel stop (14) in figure A1.
• Mount the rear flat bracket (115) and the yoke travel stop as shown in
• Loosen the grub screw (116) in the knurled knob (108) using an Allen
• Loosen the grub screw (117) in the rear support (109) and pull the
• Pass the cylinder (111) through the cylinder clamp (110) (fig. S1).
• Position the cylinder clamp (110) over the riplock (15) and tighten the
• Reassemble the rear support (109) and the knurled knob (108) and
• Position the rear support (109) as shown (fig. S3) and tighten the grub
• Push the roller head to the rear and position the cylinder in its clamp (110)
• Tighten the screw (113) in the cylinder clamp.
• Set the traverse speed using the knurled knob (108).
Bleeding the traverse control
After refilling or replacing the oil in the traverse control, the air must be
expelled from the system.
• Remove the unit from the machine and with the piston fully extended
• Remove the plug at the rear end of the bellows (114). Hold the bellows
• Refill the bellows completely with hydraulic oil Castrol 210 NRL25 or
the router bracket against the motor using the arbor nut (45) in figure F1.
Do not overtighten the arbor nut.
Always feed the workpiece against the rotating cutter.
