Description
T01067en.fm 14
4.3 Functional description
The floor saw must only be operated in a forward direction (see arrow).
The drive motor (1) attached to the frame drives the cutting blade via
the belt (2).
The cutting blade can be infinitely adjusted by means of a crank
handle (3), 1 turn corresponds to a cutting depth adjustment of 5 mm.
The cutting blade guard (4) can be swiveled upwards to make it easier
to assemble and disassemble the cutting blade.
Furthermore, the cutting blade guard can be connected with the water
tank by means of a hose (5) and an adapter.
Wetting the cutting blade with water prevents dust from developing.
The adapter on the water hose allows the connection of an external
water supply.
The drive motor speed can be infinitely adjusted by means of the gas
throttle lever (6), whereby the optimum cutting blade speed is reached
when the drive motor is operated at full throttle.
To facilitate the starting procedure, the drive motor is equipped with a
choke.

4.4 General instructions for use for diamond-edged cutting blades
∗Never use a cutting blade with a larger diameter than necessary in or-
der to cut a certain depth.
∗If the cutting blade comes to a standstill, remove it from the cut before
starting the machine again. If the cutting blade comes to a standstill in
the cut, check whether the belt is tightened adequately. Check the ten-
sion screw and make sure that it is tightened properly.
∗Cut in a straight line. Mark the cutting line clearly in such a way that the
operational personnel can follow it easily. This is to ensure that the
floor saw machine does not need to be redirected from one side to the
other (avoid cutting tight curves).
∗Sufficient drive power is essential! When cutting, work at full throttle.
∗Caution on steep tracks and levels! The machine must not exert lateral
force against the blade.
∗Never exceed the maximum speeds (imprinted on cutting blade)!
∗Use a suitable diamond-edged cutting blade for the material to be cut
(asphalt, concrete ...). Wacker Neuson offers an extensive range of di-
amond-edged cutting blades in different qualities.
∗Do not cut into the gravel area using diamond-edged cutting blades.
When cutting on the edge of the track or when cutting two different ma-
terials (cutting in the joint area), uneven wear is possible. Check care-
fully for irregularities (reinforcements etc.) in the material to be
processed. These can overload the cutting blade very quickly. When
starting cutting operations, work carefully and with a low down speed.
∗Do not process loose materials (e. g. paving stones).

Transport to the worksite
T01111en.fm 16
5. Transport to the worksite
Requirements:
∗When transporting the floor saw, use only suitable hoisting gear with a
minimum load-bearing capacity of 150 kg.
∗Always turn off the motor during transportation!
∗Empty the water tank!
∗Remove the cutting blade prior to transport. Set the lowest cutting po-
sition on the floor saw.
∗Remove the water tank and attach the hoisting gear on the transport
strap (1) for lifting.
∗If you transport the floor saw on the cargo area of a vehicle, strap it
down securely on the special safety bar.
∗Fold the guide wheel to the top and the handles to the front (or the stir-
rup handle to the top).
∗Handles, guide wheel and other operating controls must not be used
as attachment points.
Note: Also observe the regulations in the chapter Safety information.

Operation
6. Operation
6.1 Adjusting the handle
6.1.1 Handle
The width and height of the handles can be adjusted according to the
use and the body height of the operator. To do this, release the
clamping lever (1) and apply it in the new position.
6.1.1 Stirrup handle (alternative version)
The height of the stirrup handle can be adjusted according to the use
and the body height of the operator.
Loosen the knurled screws (1) on both sides, swivel the handle to the
desired position and retighten the two knurled screws.

Operation
T01110en.fm 18
6.2 Adjusting / Aligning the guide wheel
6.2.1 Adjusting the guide wheel
The guide wheel is designed to help the operator in making long,
straight cuts. The guide wheel can be exactly adjusted to the cutting
blade by loosening the jam nut (1) and turning the screw (2).
6.2.2 Aligning the guide wheel
To do this, make a cut of approx. 2 m length on a flat surface and with
the minimum cutting depth. Then pull back the machine without lateral
force. Then you can align the guide wheel exactly with the cut.

T01110en.fm 19
Operation
6.3 Cutting depth setting
With the crank (1) you can set the cutting depth precisely. One turn
changes the cutting depth by exactly 5 mm. Turn the crank in the
clockwise direction to increase the cutting depth and turn it in the
counterclockwise direction to reduce the cutting depth.
Note: You can also insert the supplied tool into the receptacle (2) near
the crank and thus prevent an unintentional change of the cutting
depth.
6.4 Depth of cut indicator
You can use the indicator to check the cutting depth currently set. It
features a cm-scale and an inch-scale. You have to adjust it to the
diameter of the blade currently installed to obtain the correct value. To
do this, turn the crank (1) until the blade touches the ground, loosen
the clamp (2) and push the sleeve (3) with the scale up to the bottom
of the sleeve. Then tighten the clamp (2) again.

Operation
T01110en.fm 20
6.5 Water tank
The floor saw features an integrated, removable water tank (1).
To fit the water tank, attach the retaining clamp (2) and tighten it with
the strap (3).
To remove the water tank or to attach an external water supply, you
can disconnect the hose on two different spots (4).
The amount of water can be regulated or stopped (5).
Note: You should remove the water tank if the machine is connected to an
external water supply.
