The following points are important for a correct and efficient machine installation:
• Position the machine with the aid of a spirit level to en-
sure that the machine functions precisely and operates
smoothly.
• Compensate for uneven floors with the „adjusting
screws“ or bolster the machine
• The machine should be bolted to the floor with M10
screws for optimum stability, however take care not to
overtighten the fastening bolts as this will increase vibrations. It is advisable to place vibration dampening
pads between the floor and the machine.
• Install the machine in such a way as not to amplify the
vibrations and machine noise.
• Ensure that workplace lighting is adequate.
• If the machine is to be installed between other ma-
chines, leave at least 80 cm distance in-between, in
order to avoid collisions when cutting large workpieces and to allow the use of equipment such as roll
supports and additional tables.

Operation
Before starting work:
• Before assembling and installing the machine, check
to make sure it is complete and in good condition.
• Ensure that there is sufficient space to work around
the machine.
• Keep the work area orderly and clean. Components
and tools that are not put in their correct place or put
away may be the cause of accidents!
• Ensure that all safety devices have been installed
properly.
• Adjustments to the machine or tool replacement may
only be conducted once the machine has stopped.
• Only clamp authorised tools to the machine.
• Install the dust extraction system according to the
instructions and test its function.
• Only machine workpieces that can be safely placed
on the machine and guided.
• Carefully inspect workpieces for foreign matter (nails,
screws) which might impair processing.
• Support long workpieces with additional surface
equipment (e.g. Table extensions, roll supports).
• Ensure that each unit is rotating in the proper direction.
• Keep tools for handling short and narrow workpieces
close at hand.
• Before switching on the machine, always check to make
sure that there are no other persons in the immediate
vicinity of the machine.
During operation:
• When changing to another workpiece or if a
malfunction occurs, first switch off the machine and
then secure it against being switched on again
accidentally.
• Do not switch off, circumvent or decommission
protective and safety devices during operation.
• Do not overload the machine! It is safer and performs
better if operated within its power range.
When working on or with the machine, the following
must be strictly observed:
• Persons with long hair who are not wearing a hairnet
are not permitted to work on or with the machine!
• It is prohibited to wear gloves while working on or
with the machine.
When working on or with the machine, the following
must always be worn by personnel:
• Sturdy, tight-fitting clothing (tear-resistant, no wide
sleeves, no jewellery (rings, bracelets, necklaces,
etc.)).
• Protective footwear To protect the feet from heavy
falling objects and prevent sliding on slippery floors.
• Hearing protection To protect against loss of hearing.
32
Attention! Risk of material damage!
!
Only operate the machine in ambient temperatures from +10°C to +40°C. If the instructions are not followed, damage may occur to bearings.
Improper use such as cutting too tight a radius or with too much cutting pressure could cause friction and
lead to sparks being generated by the blade guides.
In order to prevent sparks being generated, it is recommended that Super Glide (article number 10.0.010)
is used on a regular basis (sprayed on to the guides).

8.2 Blade selection and maintenance
Selecting the type of saw blade and its width, depends on the material to be cut and the type of cut:
• Narrow saw blades are designed for curved and circular cuts, whereas wide saw blades are designed for straight cuts.
• A fine-toothed saw blade is required for hard wood, whereas a coarse-toothed saw blade is required
for soft wood.
Operation
The following saw blades may be used:

The gap between the individual teeth should be large
enough to carry the material chips and to throw them
away. If the gap is too small, the blade will overheat and
rupture.
Do not use kinked, ruptured or bent saw blades.
For soft wood, the set should be a max. of twice the
thickness of the saw blade and for hard wood, a max. of
1.5 times the thickness of the saw blade.
Fig. 8-2: Release saw band tension
Attention! Once the machine is no longer in use, loosen the belt tension and place an appropriate
warning sign on the machine. This will thus prevent damage to the wearing surface of the wheels. (see illustration)

9.2 Tightening/replacing the drive belt
Over time, the drive belt will lose its capacity to transmit
power. At this point, the drive belt must be re-tensioned
or replaced.
!
• Ensure that there is sufficient space to work around
the machine.
• Keep the work area orderly and clean. Components
and tools that are not put in their correct place or put
away may be the cause of accidents!
• Install the safety equipment according to the
instructions and check that it functions properly.
The drive belt must be inspected monthly; if tears are
discovered, the drive belt must be replaced.
Following the first few operating hours, the belt tension
has to be controlled, as the belt will extend.
To check the tension, press inwards onto the belt in the
middle with a weight of 3-4 kg.
The belt deflection should not be more than 5-6 mm.
Retensioning the drive belt:
1. Loosen the nuts.
2. The motor must be swivelled to tension the drive belt.
3. Tighten the nuts.
Fig. 9-1: Drive belts
! Nut
42
It is important to always maintain the correct belt tension,
as belts which are too loose will weaken the drive power
!
Attention! Risk of material damage!: Do not over-tension the drive belt!. Tighten the motor only until sufficient power transmission is ensured.
and the brake power and belts which are overtightened
will lead to overheating.
