Transportation of the machine (Fig.1-2-3)
The machine is received in a crate made of heavy duty particle board panels, which can be easily
recycled.
By using hoist equipment the machine can now be lifted with a small crane of forklift truck,
but severe jolts must be avoided (g.1)
When the machine is placed on the ground, it is still possible to move it by removing the front cover
plate and placing a hand pallet truck in the two openings in the front of the frame (2).
The machine must be leveled in both directions to assure good sliding motion of the sliding table.
Four leveling bolts must be put in before the machine is placed on the oor : one bolt in each corner
of the frame (g.3)
If possible, the machine must be placed on rubber plates which act as shock absorbers and reduce the
noise level.

Electrical connection (Fig.4-5)
The electrical connection must be carried out by a qualied electrician who is able to calculate
exactly the required wire cross-section and capacity of the workshop fuses.
Check that the mains voltage of the machine corresponds with the voltage supply to your workshop.
Now remove the electrical connection box and introduce the cable. Connect the 3 phases to the
terminals on the connection block marked L1, L2, L3. If there is a neutral conductor (blue) it must
be connected to the terminal N.
Connect the earth wire (green-yellow) to the terminal marked with the earth symbol PE.
Attention : Check rst if the saw spindle runs freely and if all safety devices are tted before starting
the machine.
If the direction of rotation of the sawblade is not correct, the wires L1 and L2 must be exchanged
(clockwise direction of the spindle is correct).
For safety reasons this must only be done without the sawblade on the spindle !
Thermal overloads
The machine has overload protections on both saw and scoring motors. Should the motor be shut-off
by one of these protectors, it is necessary to wait a few minutes untill the overload has cooled down.

Starting up the machine (Fig.6)
Turn the main switch (1) to position “1”.
To start the main saw motor push the start button (2).
The scorer motor is started by pushing the start button (3); this is only possible with the main saw
motor running.
By pushing the emergency stop- button (4) both the scorer- and main saw motor are stopped.
Mounting of the E300 sliding table (Fig.7)
The position of the sliding table relative to the machine is factory set and needs no further
adjustments.
The adjustment bolts C are height setting bolts set at factory. To ensure a clean and neat cut the
sliding table has to be set 100 % parallel to the sawblade.
To correct the parallelism between sliding table and sawblade use bolts A.
After adjustment tighten all the bolts previously loosened.

Mounting of the E-2800 sliding table on
the machine (Fig.7 bis)
The position of the sliding table relative to the machine is factory set and normally needs no further
adjustments.
Simply put the table onto the frame with the two lateral adjusment bolts in the two lugs placed at
each side of the frame.
These lateral adjusment bolts are also factory set and normally need no adjustment.
Now place the 4 big Allen bolts into the lower section of the sliding table: ensure the table does not
flip over when sliding away the upper section of the sliding table.
These 4 bolts need to be tightened with a Torque wrench at 80 Nm (8 kgs.)
This is best done by an experienced Robland technician thus avoiding serious problems with the loss
of warranty on the sliding table as a result.
To ensure a clean and neat cutting result the table has to be given a free cut left: the sliding table
does not run exactly parallel to the saw blade, it runs away from the back teeth by a fraction of a
millimeter.
All saw blades vibrate to some extent: they flutter less at the front where the cutting teeth are held
stable by the material than at the back.
If the table were set absolutely parallel to the saw blade, the back teeth could retouch the material
and spoil the clean cut achieved by the front teeth.
As the back teeth are ascending they could cause chip-out on the top surface of the laminated
boards
(back cutting).
To correct the free cut, loosen slightly the vertical 4 big Allen bolts and loosen the nut of the lateral
adjustment bolt at the far end of the sliding table. Adjust, and re-lock the stop bolt at the end you’re
adjusting.
Recheck the free cut if OK and make final test cut.
Make sure the 4 big Allen bolts are well tightened and locked at 80 Nm.

Changing main sawblade and scorer
sawblade (Fig.8-9-10)
Before changing sawblades always turn off the main switch (g.6.1).
Handle saw blades with care, to avoid serious cuts and injuries.
The use off HSS saw blades is prohibited, use only carbide tipped saw blades.
The maximum diameter of the saw blades used on the machine is 315 mm.
Push the sliding table to the rear and open the saw cover (g.8). Raise the main sawblade to its
highest position and put the key(3) into the saw arbor nut.
Put the locking pin (g.9,2) in the opening of the sawtable and turn the arbor with the spanner untill
the locking pin (2) engages in the hole in the saw arbor pulley.
Now unlock the nut.Warning: the nut has a left thread, so loosen by turning the nut in the anticlockwise
direction. Before tting the new sawblade ensure the blade and anges are clean. This
prevents wobbling of the sawblade.
Never forget, after the saw arbor nut has been tightened, to remove the locking pin from the pulley
before starting up the motor.
The scorer saw blade is changed as follows : turn the scorer blade to the left and put the spanner
(g.10,1) onto the atened arbor. Loosen the bolt with the Allen

Use and adjustment of the riving knife
(Fig.11)
The machine is equiped with a riving knive for the use of sawblades upto 315 mm.
The riving knife has to be adjusted in such a way that over its entire length the gap between sawblade
and riving knife does not exceed min.3 mm and max.8 mm.
The riving knife (1) can be adjusted in both vertical and horizontal direction.
The height setting has to be adjusted in such a way that the highest point of the riving knife never
exceeds more than 3 mm above the highest placed sawblade tooth.
After height adjustment always lock the central bolt (3) (with 25Nm). The 3 little adjustment screws (2)
are used for the exact setting of the riving knife in line with the sawblade.
For slotting or grooving the riving knife has to be adjusted in such a way that the upper part of the
riving knife is never set lower than the highest sawtooth in use.
Never remove this riving knife. Kickbacks are severe and very dangerous.

Settings of main and scorer sawblades
(Fig.12-13-14)
Height setting of main sawblade (g.12)
Main sawblade height setting is done by turning the handwheel (1).
One turn of this handwheel equals 2,5 mm of height setting.
In order to remove the mechanical play on the rise and fall spindle, always set the height
by rising the sawblade.
Height setting of the scorer sawblade (g.12)
The height setting of the scorer sawblade is done by turning the knob (2), and locking the serrated
knob. One turn of this height setting knob equals 3 mm.
The maximum cutting depth using a scorer sawblade diameter of 120 mm is 4,5 mm .
Tilting of the sawunit (g.13-14)
By turning the handwheel (1) the whole sawunit can be tilted and set at any angle between 90° and
45°. After setting, lock the sawunit in this position using the locking handle (2).The angle can be read
at the scale.
Both 45° and 90° positive stops are factory set and need no adjustment. After setting the
sawunit at the desired cutting angle the cutting depth of the scorer must be set again.
Lateral adjustment of the scoring blade
Each time the main sawblade is replaced by a new one, or even a newly sharpened sawblade, the
scorer has to be adjusted to match the main sawblade teeth width. It is very important that this is
done in the correct way to ensure a clean cut, free of splintering.
The use of two piece scoring saws is best because they can easily be adjusted using spacer rings.
The lateral movement of the scorer sawblade is achieved by turning the knob (g.12,2) and locking
the serrated knob.

Operating the E-300 sliding table (Fig.15)
When loading panels and when cutting using the parallel fence the sliding table should be
locked.
To lock the table pull the locking lever (1) in one of the three slots in the side cover plate of the
sliding table.
If over a long period of time many short movements of the sliding table are made by e.g. crosscutting
solid wood, then it is possible that the ball carrier between the upper and lower part of the
sliding table will move. This means it will no longer be correctly positioned to allow the sliding table
to slide through its full course.
The operator will feel resistance in the sliding table motion and the full stroke will not be achieved.
This effect can be corrected simply by pushing the table with a few short, light pushes against the
buffer stop at the end, until the position of the ball carrier is adjusted and the table can be moved
again along its full stroke.
Maintenance and lubrication of the sliding table
It is highly recommended to clean the sliding table once a week, and to remove all sawdust and chips
which gradually slow down the sliding table. From both sides of the sliding table blow out the dust
which has accumulated between the two sections and on the ball carrier.
This can be done more easily and efficiently when the upper part of the sliding table is slid to the rear,
and must then be repeated with the upper part at the front end.
After all dust has been blown out, a thin oil, such as WD-40, should be sprayed onto the steel inserts
on both the upper and lower part of the sliding table. Never use a thick oil or grease ! This
maintenance job will only take 10 minutes of your time, and will ensure the
machine gives full satisfaction.

Operating the E-2800 sliding table
(Fig.15 bis)
When loading panels and when cutting using the parallel saw fence, the sliding table should be
locked.
There are two different systems to achieve this. The rst system is used when loading the panel onto
the sliding table to prevent the table from sliding away from the operator.
To lock the table in the front position put the arrow on ‘A’. When the sliding table is pulled to the
front it will automatically be locked in this position.
To unlock the table: pull the handle and put arrow on ‘B’.
The second system is for cutting with the parallel saw fence: simply pull the bolt (g.15,1) and engage it
in one of the tree slots along the side of the sliding table

Mounting of the cross-cut table (Fig.16)
The cross-cut table can be slid from the back onto sliding table via the at bar on the side of the
sliding table.
The 2 brackets (2) should be positioned to allow the cross-cut table to be easily moved along the
sliding table. The table is locked in position using handle (1).
Please note that the machine is constructed so that the cross-cut table can only be put at the far end
side of the sliding table.
The telescopic arm support is too short to allow the cross-cut table to be set at the front of the sliding
table. Both telescopic arm and cross-cut table are factory set and need no further adjustment.
Mounting of the 90° cross-cut fence
(Fig.17)
The cross-cut table has 4 precision holes allowing the fence to be put in 2 positions : at the back and
front of the cross-cut table. Simply put the fence onto the cross-cut table and lock it in position
using the two serrated nuts (1).
The 90° right angle of the fence is factory set. Should the 90° angle need to be adjusted, then the two
bolts (2) must be loosened; then by turning the little bolt (1), the angle can be opened or closed
towards the sawblade. After adjustment the bolts (2) have to be retightened.

Calibration of the scale on the
cross-cut fence (Fig.18)
The scale on the fence is factory set and needs no further adjustments.
To check the settings, put the stop at a certain measure and cut off a sample.
Measure the exact length of the sample, unlock the screw which holds the fence and move the fence
until the measurement corresponds to the length of the previously cut length.
The scale on the telescopic part of the fence is factory adjusted to the scale of the xed part of the
fence.
When using the telescopic extension, the second repetition stop (3) has to be set at
1550 mm to make the different scales correspond with one another. The best way to check if all
scales correspond is to make several test cuts on the different scales.
When, after some time, the wooden protection cap at the front on the cross-cut fence is cut away, a
new one has to be made according diagram g.18.
Mitre fence (Fig.19)
The at T-nut which holds the vertical rod of the wood clamp is factory set and has to stay in its position
to make the angle scale correspond.
To set the required angle : unlock the rod of the wood clamp (1), and the auto-release handle (2). To
slide the fence (5) towards the sawblade, unlock the two handles (3). Reading the angle set is done at
the back of the aluminum bracket which holds the fence.
Always set the aluminium mitre fence prole (4) as close as possible to the saw blade.
To move this aluminium prole, loosen both locking handles on the corner bracket.
Removing the complete mitre fence is easy: loosen the vertical post of the wood-clamp and the locking
handle (2) and take the fence off of the sliding table.
The at nut should always stay in the sliding table groove.

Use of the parallel fence (Fig.20)
To move the fence, unlock the serrated knob (3) and lift the handle (2).
To lock the fence in position push the handle (2) down and lock the knob (3).
The micro adjustment is achieved by locking the knob (3), by holding the handle (2) in the upright
position and by turning the serrated knob (4).
After the adjustment push handle (1) down to lock the fence in place. When cutting small workpieces
with the sawunit inclined at 45°, the fence should be used in the low position.
Simply unlock the eccentric clamping handle (5), slide off the fence and slide it back on in the low
position.
Lock the fence with the eccentric clamping handle (5).
When cutting solid wood using the parallel fence, to avoid the wood getting stuck between the fence
and the riving knife (resulting in a hightly dangerous kickback) it is recommended to reposition the
fence so that its end protrudes just past the end of the riving knife.
