below the table and move the scale and rip fence guide (C, Fig
12) sideways to adjust.
Fig 12
Re-tighten the winged screws when the adjustment is correct.
The adjustment can be checked by setting the rip fence to a
thickness and cutting a test piece.
When the adjustment is correct the thickness of the test piece
will correspond with the rip fence scale setting.
Checking the table for flatness
A steel rule should be held on the table across the table slot
close to the front edge of the table. (See Fig. 13)
Fig 13
If the straight edge shows there is a step across the table slot
then the table needs to be adjusted using the two screws and
locking nuts provided for this purpose, located on the
underside of the rip fence guide, at (D, Fig 13)
Lower blade guard
When open the lower bandwheel door on this machine the
lower blade guard (C, Fig 14) swings down.

The flow rate on the suction port must be 20m/sec.
Flexible hoses must be of non-flammable quality, and must be
connected to the machine ground system.
5.4 Starting operation
You can start the machine with the green on button. The red
button on the main switch stops the machine.
6. Machine operation
Correct working position:
In front of the machine standing in the direction of cutting.
Workpiece handling:
Hands placed flat on the workpiece outside the cutting area.
Feed the workpiece towards the saw blade in the direction of
the saw line, and cut as required by turning to follow the line
drawn. Push the workpiece steadily forward; complete the cut
as a single movement. Do not draw the workpiece back, as this
could cause the sawblade to run off its wheels.
Support long and wide workpieces with helping roller stands.
Operating hints:
Work only with a sharp and flawless sawblade.
Near the cutting area use a push stick to feed.
Use a feeding template to safely guide small and narrow
workpieces.
Use a suitable wedge to prevent round timber from turning
under the pressure of the cut
Workpiece setup:
Bring the upper blade guide to a distance of approx 2-5mm to
the workpiece. (See Fig 16).
Fig 16
For your own safety, always set the saw guide as close to the
workpiece as possible.
To adjust the cutting height release the winged nut (A, Fig 17)
and move the upper blade guide and guard assembly (B).
Fig 17
Blade Drift Compensation:
Blade drift is a frequent problem on rip cuts and during
resawing.
Blade drift may occur when the fence is being used, the blade
begins to wander off the cutting line (Fig 18).
.
Fig 18
Blade drift can be caused by a number of factors.
- The saw blade follows the grain
- The saw blade is dull.
- Blade guides not adjusted correctly.
- Blade tension unsufficient.
- Blade-teeth have asymmetric“set”
With the blots (D and E, Fig 19), the rip fence profile can be
angled. This allows guiding the workpiece in line with cut.
Fig 19
10
Auxiliary fence for rip fence:
For your own safety always set the upper saw guide as close to
the workpiece as possible.
For narrow shallow cuts on the rip fence a self-made auxiliary
fence (E, Fig. 20) made of cutable material ( e.g. wood, plastic,
aluminium) must be used.
Length same as rip fence.
Fig 20
Mitre gauge:
Place the mitre gauge in the table T-slot.
Directions for “safe operation“ :
