2.1 Short description
The Floor Saw CS1 you have chosen, is used for small repair works in concrete and asphalt,
for cutting induction loops and installing cables as well as for cutting expansion joints. It can be
used for either wet or dry cutting operations. Being of small construction, it can be transported in
a car or van. The water container is enclosed in the frame. All component parts on the CS1 are
assembled to a high quality standard, ensuring long life, reliability and a minimum of
maintenance. Special types of blades are available for asphalt, green concrete, cured concrete
(reinforced or not) as well as for industrial cement flooring.
2.2 Layout
Made of jig welded open profile steel, the CS1 is stable but at the same time, easily
transportable.
The one-piece blade guard (1) fully protects the operator and his working environment. It is
firmly fixed to the main frame but can be opened by rotation to change blades.
A manually operated hand wheel mechanism (2) enables graduated depth setting. Turning the
hand wheel clockwise or anti-clockwise will lower or raise the cutting blade.
8
Page 9
The pivoting frame (3), hinged on the rear axle, is supporting the engine, the blade shaft
assembly, and the protecting guards. Four heavy-duty belts drive the blade.
The precisely manufactured blade shaft is fitted into two heavy-duty self-aligning pillow block
bearings, including grease nipples. A four-belt taper lock pulley is fitted on one end. The shaft is
reduced to 25,4mm at the other end, allowing an inner flange complete with dowel pinholes to
be fixed.
The steel belt guard (4) is bolted to the mainframe of the machine. It is covering the four drive
belts and pulleys for protection of the environment while the machine is running. The pointer (5)
allows the operator to make precise cut easily.
The Honda GX390 engine (6) is connected to an emergency shut down switch (7) on the board
of the machine. This allows an immediate stop of the machine in case of danger. The water
cooling system (8) is composed of a 70 litres water tank, a water tank tap and two water nozzles
on the blade guard ensuring adequate flow of water to both sides of the blade.

3 Assembly and commissioning
Before beginning the work with the CS1, you have to assemble some parts.
3.1 Tool assembly
Only use NORTON blades with the CS1.
A blade with a maximum diameter of 500 mm can be fitted. All tools used must be selected with
regard to their maximum permitted cutting speed for the machine’s maximum permitted rotation
speed.
Before mounting a new blade, switch the machine off.
To mount a new blade, follow these steps:
• Turn the wheel until the cutting head is in the raised position.
• Loosen the screw maintaining the blade guard with the 19mm wrench, and turn it open.
• Loosen the hexagonal nut, which holds the removable outer flange with the 36mm wrench.
• Remove the outer flange.
• Clean the flanges and blade shaft and inspect for wear.
• Mount the blade on the shaft ensuring that direction of rotation is correct. Wrong direction of
rotation blunts the blade quickly.
• Replace outer blade flange.
• Tighten hexagonal nut with spanner supplied for this purpose.
• Close the blade guard.
The blade bore must correspond exactly to the blade shaft. Cracked or damaged bore is
dangerous for the operator and for the machine.
3.2 Water cooling system
Fill the water tank with clean water.
Open water-tap (note that handle on water-tap should be in line with water-flow).
Ensure that water is flowing freely in the circuit and delivered adequately to both sides of the
blade, as insufficient water supply may result in premature failure of the diamond blade.
In case of frost, empty the water cooling system.
10

3.3 Starting the machine
Make sure the blade is raised clear up the ground before starting the machine.
Turn the fuel valve to the ON position. Move the choke lever to the CLOSED position.
NOTE: do not use the choke if the engine is
warm or the air temperature is high.
Move the throttle control lever slightly to the
left.
Put the engine switch on ON, and make sure
the emergency switch on the board of the
machine is in the correct position.
Pull the starter grip lightly until you feel
resistance, then pull briskly.
CAUTION: Do not allow the starter grip to snap
back against the engine. Return it gently to
prevent damage to the starter.
To stop the engine, move the throttle control lever fully to the right, then turn the engine switch
to the OFF position. Turn the fuel valve to the OFF position.
As the engine warms up, gradually move the
choke lever to the OPEN position.
Position the throttle control lever for the
maximum engine speed.

5.2 Cutting method
In this section, you can find instructions to make a straight cut at the desired depth.
5.2.1 Preparing your cut
Before starting the machine,
• Draw a line on the floor over the cutting length.
• Make sure you have filled the engine tank with fuel, and the water tank with water. No petrol
is supplied with the machine.
• The engine is shipped with oil. Check oil level before starting. Top up if required.
• Make sure you have mounted the correct blade as recommended by the manufacturer
depending on the material to be worked, the working procedure (dry or wet cut) to be carried
out, and the efficiency required.
• Make sure that the flanges securely hold the diamond blade.
• Make sure that the blade is not touching the floor before starting.
• Roll the machine until the blade is over the line.
• Lower the guide-a-cut so it touches the line.
5.2.2 Cutting the floor
You can now start the engine.
To make your cut,
• Turn the depth hand wheel until the blade slightly touches the floor.
• Open water valve to control the amount of water required for the type of blade, using 15 to
25l/min for wet and 1-2l/min for dry cutting, dust control. Check for minimum water level
regularly.
• turn the hand wheel to lower blade into the cut.
• Once the required depth of cut is reached, push the machine forward with steady and gentle
pressure and follow the line with the pointer. The feed speed must be adjusted depending
on the material being cut, and depth of cut.
• At the finish of the cut, raise the blade out of the cut by turning the hand wheel, switch off
the engine and shut-off the water.
