APPLIANCE
The sawbench type 130 is only to be used for
cutting wood and wood-like panels (e.g.
chipboard, block board, MDF etc.)
Maximum panel sizes:
Height: 110 mm
Between saw-blade and
rip fence: 1250 mm
Length (not supported): 1000 mm
Cutting of other materials with the standard
saw-blade is prohibited. Cutting other materials
with a special saw-blade only with permission of
manufacturer.
All other appliances except for the above are
improper use of the machine and therefore
prohibited. The producer cannot be held
responsible for damage as a result of improper
use. Damage will be recovered from the user
The machine may not be operated, used or
maintained by persons not acquainted with the
risks of the machine.
Permission for operating, using and maintaining
the machine have to be clearly described by a
person or persons responsible within the
organisation.
Maintenance has to be performed by the
manufacturer or customer service.
One has to be acquainted and comply with the
country's applicable safety regulations.
Only original Harwi parts are to be used.
We cannot give warranty or be held responsible
for damage caused by using non-original Harwi
parts.
The manufacturer cannot be held responsible
for damage caused by changes made to the
machine by the user.
REMAINING RISKS
If the machine is completely used according
to all safety regulations there still will
remain some risks:
Touching of the saw-blade with the
sawing area.
Touching of the saw-blade when the lid is
opened
Breaking of the saw-blade or parts of the
saw-blade hurtling out of the guard.
Touching of parts under voltage while
junction box or switch is opened.
Damage to the hearing by constant use
of the machine without ear protection.
Throw out of harmful dusts or vapours by
using a dust extractor with bad
performance or no dust extractor at all.

GENERAL INDICATIONS/SAFETY REGULATIONS
Harwi Holland B.V. has bestowed great care
on compiling this manual. Before operating the
machine read the complete manual carefully.
Persons under the age of 18 are not allowed to
work on or with circular sawing machines.
Except for a training program on a legal basis.
The machine may only be operated by
educated personnel or under supervision of
educated personnel.
To avoid touching with rotating saw-blades
make sure that:
Clothing fits tightly to the body
Work with closed fingers
No rings or other jewellery are worn.
A hairnet is used by long hair.
Be careful when changing the saw-blades.
They are sharp and cause injuries.
Do not remove woodchips when the saw-blade
is running. Stop the machine first.
Broken saw-blades or blades or deformed
blades are not to be used. Neither are HSS
blades
The applied saw-blade is to be used and
sharpened according to the directions of the
manufacturer.
Sharpening only by competent craftsmen.
Stick to max. admissible r.p.m. mentioned on
the blade. Preferably use noise-reduced saw-
blades.
Flexible hoses of the dust extractor have to be
from a highly inflammable quality (according to
DIN 4102).
The safety guard and other safety equipment
may not be removed or put out of order.
Assembling or repairs are only to be performed
if the machine cannot be switched on. The
switch or the main switch are to be switched off
and locked with for instance a padlock.
Repairs to the electricity supply are only to be
executed by skilled craftsmen.
When leaving the working area make sure that
incompetent persons cannot switch on the
machine. It is obligatory to wear dust-mask, ear
protection and safety glasses.
Take care of a clean working area.
The machine has to be lighted. When using
strip lighting take into account the stroboscopic
effect. A rotating saw-blade seems to be
standing still.

- MP for the zero
- PE for the earth
4 Close the switch.
Notice: Use cartridge fuses of min. 25 Ampere.
Notice: Check the rotation of the saw (see
chapter DIRECTION OF SPINDLE
ROTATION).
Figure 2

10
DIRECTION OF SPINDLE ROTATION
Disconnect the mains supply with the main
switch at the backside of the machine.
Remove the table insert, the saw nut, the
flanges and the saw-blade (see chapter
CHANGING THE SAW-BLADE).
0 Put the motor in the highest position.
PROPER DIRECTION IS CLOCKWISE
(Looking from the front side of the spindle to the
motor, fig. 3).
1 Connect the mains supply.
2 Switch motor on and off.
3 Check if direction is clockwise.
4 Disconnect the mains supply with the
main switch.
5 Put saw-blade, flanges and saw nut back
(see chapter CHANGING THE SAW-
BLADE).
6 Put table insert back.
WRONG DIRECTION IS ANTI
CLOCKWISE
(Looking from the front side of the spindle to the
motor fig. 3).
1 The spindle turns anti clockwise.
2 Disconnect the mains supply.
3 Open the switch at the backside of the
machine and interchange two phases.
4 Check the rotation again.
5 Disconnect the mains supply with the
main switch.
6 Put the saw-blade, the flanges and the
saw nut back on.
7 Put table insert back.
Figure 3

11
CHANGING THE SAW-BLADE
Notice: Before changing the saw-blade
disconnect the main switch at the backside
of the machine and secure it against
switching on with a lock.
Noise reduced saw-blades are preferred. Use
a suitable saw-blade. Enquiries at you supplier
or the manufacturer.

spindle and the nut.
6 Put the saw-blade and flange back again.
Notice: spindle rotation is clockwise.
7 Check the position and the thickness of
the riving knife.
8 Put the table insert back.

Figure 4

12
ADJUSTING THE RIVING KNIFE
Check the thickness and the measures of
the riving knife. The riving knife has to be
thicker than the blade body but thinner than
the tooth thickness.

switch and secure it against switching on.
2 Remove the table insert.
3 Put the saw-blade in its highest position.
4 Loosen the bolt of the riving knife
fastening.
5 Adjust the riving knife in such a way that
the distance between the knife and the
teeth sticking out above the tabletop is
maximum 3 mm. The highest point of the
riving knife has to be 3-5 mm under the
highest point of the teeth (fig. 5).
6 Fasten the bolt of the riving knife
fastening tightly.
7 Put the table insert back.
8 Connect the mains supply.

OPERATING THE MACHINE
RIPPING
SAFETY
When ripping solid wood, put the saw-blade
as high as possible. The sub-fence max. 10
mm past the point where the blade cuts the
wood at full height.
Adjusting the sub-fence properly prevents
the return shock of the wood or a part of it.
Use a push stick when cutting small wood.
Adjusting the riving knife (fig. 6).
1 Adjust the rip fence with the sub-fence at
the desired measure.
2 Check if the saw-blade can rotate freely.
3 Switch on the motor.
4 After cutting switch off the motor
immediately.
5 Remove the material after the saw-blade
has stopped.
Notice: If the saw-blade stops because of
clamping of the wood, switch off the motor.
Hold the piece of wood tightly!
Notice: Never stand in the line of the saw-
blade. In case of a return shock you might
get hit.

OPERATING THE MACHINE
MITRING WITH THE MITRE FENCE
SAFETY
When mitring NEVER use the ripping fence
as a stop.
1 Put the saw-blade in its highest position.
2 Put the material on the machine (fig. 7).
3 Push the wood against the fence.
Notice: Support the wood properly.
4 See to it that the wood and the fence do
not touch the saw-blade.
5 Switch on the motor.
6 Move the fence and the wood forward at
a constant speed and cut the material.
7 Switch off the motor.
8 Remove the material after the saw-blade
has stopped.
Notice: If the saw-blade stops because of
clamping of the wood, switch off the motor.
Hold the piece of wood tightly!
Notice: Never stand in the line of the saw-
blade. In case of a return shock you might
get hit.
