Operating instructions
3 Installation
Place machine upside down on two battens to install the workstand. Do not tighten screws fully before all parts have been
installed.
Install suction port to chip case.
Use 3 each
hex. head screw M 6x16
serrated lock washer Ø 6.4
hex. nut M 6
Install dust collection port into hole of the
rear panel with 3 each
hex. head screw M 6x16
serrated lock washer Ø 6.4
hex. nut M 6
Place spiral hose Ø 100 mm onto suction
port and secure with hose clamp Ø 100
mm. Install both side panels, using 4 each
hex. head screw M 6x16
serrated lock washer Ø 6.4
hex. nut M 6
Place the spiral hose on the dust collection port and secure in place with the
second hose clamp Ø 100 mm.
Install rear panel (with hole) between the
side panels.
Use 6 each
hex. head screw M 6x16
serrated lock washer Ø 6.4
hex. nut M 6
Install the workstand's front panel.
Use 6 each
hex. head screw M 6x16
serrated lock washer Ø 6.4
hex. nut M 6
Put a hex. nut M 10 on the threaded bolt
of all 4 adjustable feet.
Install feet into tapped bushes M 10 located on each corner.
17
Now tighten all screw joints fully, then
stand machine on its feet. Place side
panels lids into the panel openings.
Loosely attach 2 carriage bolts M 6x16 to hose carrier, then slide hose carrier into the
rear T-groove of the table.
Install spiral hose between saw blade guard and dust collection port.
Raise saw blade (see paragraph 5) and
attach saw blade guard to riving knife.
3.1 Rip Fence Scale Adjustment
The rip fence scale is adjustable to accommodate saw blades of different widths.
Set rip fence against the blade. Loosen scale fixing screw and set scale until zero
mark matches the hairline of the fence bracket's magnifying glass. Tighten fixing
screw and verify setting by making a trial cut on a piece of scrap.
Note: The scale's zero mark and the hairline of the magnifying glass can only
line up with the fence extrusion installed in the upright position (wide edge facing
the blade).
3.2 Magnifying Class 3.3 Rip Fence Adjustment 3.4 Mitre Fence Adjustments
The magnifying glass can be removed
from the rip fence for cleaning.
The rip fence is factory set parallel with the
saw blade. If adjustment is necessary
loosen the four screws holding the fence
extrusion to the carrier and set square
with the table.
Both left and right hand 45° end stops are
factory set. If required the positions can
be adjusted with the setting screws. The
angle scale is also adjustable.
4 Connection to Power Mains
- This machine must be operated on a residual current operated device of 30 mA capacity, having a fault current breaker.
- This machine must be safety earthed. The yellow/green lead is the earth conductor.
- Fit plug matching your local standard outlet to the power cable.
- The outlet this machine is connected to must be earthed and phase protected by a 16 A time-lag fuse or circuit breaker.
- Do not operate saw with a damaged power cable. Risk of electrical shock.
Worn or defective cables must be replaced immediately. Have replaced by a qualified electrician only.
Check if voltage of power mains matches with voltage stated on machine's type plate.
For mains connection a 5-lead power cable is required. The yellow/green lead is the earth conductor. Do not connect the
yellow/green earth lead to any of the current conducting terminals. If in doubt-consult a qualified electrician.
Extension cables should have a minimum lead cross section of 1.5 mm2 and a rubber outer jacket (HO7RNF/SJT or similar).
Use of extension cables with too small a lead cross section causes a voltage drop and possible damage to motor and/or switch.
Important! Always disconnect from power before servicing the saw.
Direction of rotation of the saw blade is clockwise, when looking at it from the left side of the saw. To check start saw briefly.
If the blade runs counter-clockwise on a three-phase machine, have a qualified electrician interchange two of the phases to
correct.
Note: Wrong direction of rotation of the saw blade is dangerous and may cause severe personal injury.

4.1 Switch/Overload Protection
The switch is equipped with a no-volt release solenoid (magnetic switch), to
prevent start-up after a power failure. If the saw is not connected to the power
mains the switch does not engage. In the event of a power failure the machine
has to be restarted. In case of an overload of the main motor the build-in motor
protection relay trips and cuts the power to the motor. If the motor is shut off
repeatedly by the overload relay, check machine (motor brake action, dull blade,
low voltage etc.). A cooling down period of 30 min. is recommended.
A light humming from the solenoid inside the switch is normal and does not
indicate a fault.
- Block rotary switch knob with a padlock to prevent unauthorized use.
5 Controls/Settings
5.1 Sawblade Vertical Setting
The depth of cut of the main blade is set by turning the cranked handwheel.
Turn clockwise to raise blade
Turn counter-clockwise to lower blade
To compensate for possible play always raise blade into desired position.
5.2 Blade Tilt
After release of the ratchet lock lever inside the handwheel the blade can be tilted
steplessly to any position between 90° and 45° by turning the handwheel.
Reference point is the graduation mark to the right of the pointer.
- Tighten ratched lock lever after setting.
Caution! Carry out setting only with the blade at complete standstill.
5.3 Rip Fence Setting
Place rip tence onto the saw table. Set to
required width of cut, then push the right
hand side lock lever down.
Turn micro-adjuster screw to set fence to
exact dimension.
5.4 Opening the Chipcase
Disconnect from power before servicing!
After micro-adjustment is made push down
the left hand side lock lever to lock the rip
fence in position.
Loosen wingnut of saw blade guard a few
turns. Pull forward and up to remove blade
guard from riving knife.
Loosen starknobs located below the table
at front and rear of removable table section and push against the workstand panel.
19
Remove the removable table section.
