Intended use
The oor saw has been designed and built for the following use:
• Cutting asphalt and concrete (including reinforced concrete).
• Making plunge cuts, ush cuts and cutting joints in oors.
• Only use tools with an original hole pattern.
• If oor saws are operated in enclosed or underoor spaces, exhaust fumes from
combustion engines must be vented to the outdoors.
• Binding operating limits and characteristic data can be found in the technical data in the
operating instructions.
Improper use or misuse
• Use that is not in accordance with the intended use is considered improper use or
misuse.
• Since improper use and misuse can in some cases result in considerable hazards, we
would like to point out here the improper uses or misuses known to us.
The following types of use are prohibited:
• Cutting metal, wood and plastic
• Cutting loose parts (including in concrete)
• Operation in water and in explosion-proof spaces
• Cutting without system and tool cooling (unless dry cutting with a special diamond tool)
• Cutting without the protection devices provided
• Incorrect or no disposal of waste water (saw sludge water)
• Cutting without the protection devices provided
Electrics
Caution
Defective electrotechnical equipment is a re risk.
▶The electrotechnical equipment must be checked before each use and sporadically
during longer periods of use. Defective parts such as cables and plugs must be
replaced immediately by persons trained in electrical engineering when in a de-
energized state.
▶Check all fuses if switches or controls are not functioning properly. If fuses trip
frequently, determine the cause and repair them immediately.
Failure to observe this instruction may result in consequential damage such as re.
INFORMATION
You can nd electric circuit diagrams in the spare parts list.

Mounting the saw blade
DANGER
Death or serious injury if the saw blade ies o!
▶Only use genuine screws from Tyrolit Hydrostress AG.
DANGER
Serious injury if the saw blade starts up suddenly!
▶Switch o the oor saw before working on the saw blade.
INFORMATION
Diamond saw blades with mounting holes dia. 25.4 mm can be mounted on the oor saw.
Always use a blade guard that is suitable for the blade size.

Mounting/ReMoving 13
Proceed as follows:
9Check that the direction of rotation arrow on the saw blade (C4) matches the direction of
rotation of the engine (arrow on the blade guard).
9When mounting the saw blade on the right-hand side, use the fastening screw (C1) with
left-hand thread. When mounting the saw blade on the left-hand side, use the fastening
screw
(C1) with right-hand thread
▶Swing the saw blade spindle up (A).
▶Lift the front protective ap up 180° and secure it (B) with a locking pin.
INFORMATION
Using the correct saw blade (size and type) protects the saw blade and improves
eciency, resulting in lower costs.
▶Saw blade inspection
Inspect each saw blade before installation and discard damaged saw blades. Inspect
the saw blade for:
–Cracks, notches and dents
–Damaged/deformed mandrel (centre hole)
–Darkness/discoloration near the diamond segments
–Deformation of the saw blade circumference
–Segment loss/cracks
–Worn core
–Bending
–Sides of unequal width
INFORMATION
Spanner
A 15/16-inch combination wrench, located on the right-hand side of the control panel, is
provided for mounting and removing the saw blade.
▶Secure the saw blade C4 to the locating ange C5 using blade cover C3 and genuine
Tyrolit bolts C1/lock washers C2.
▶Swing the front protective ap down and secure it (B).
▶Carefully place the saw blade on the oor (E) to prevent the saw blade from rotating
while you are tightening the bolt.
▶Tighten the blade cover bolts to a torque of 170 Nm (F).

Water connection
Wet and dry cutting
INFORMATION
The oor saw can be used for wet and dry cutting.
INFORMATION
Special Tyrolit diamond tools must be used for dry cutting.
Water connection (diagram)
Water supply
The water supply reduces dust during cutting and cools the fuel, transmission and saw
blade.
INFORMATION
Always test the water supply for adequate pressure and ow before cutting.

Using the water supply
▶Make sure that the water valves on the right and left-hand sides of the oor saw are
closed.
▶Connect the water hose to the water valve on the left-hand side of the oor saw.
▶Check the following supply hose connections to ensure that they are not leaking:
–Supply hose from right-hand water valve to inlet of fuel cooler assembly.
–Supply hose from outlet of fuel cooler assembly to inlet of water solenoid valve.
–Supply hose from outlet of water solenoid valve to transmission inlet.
–Supply hose from transmission outlet.
▶Connect the water supply hose from the transmission outlet to the water manifold on
the blade guard.
▶Move the lever of the water valve on the right-hand side of the oor saw to the fully
open position. Increase or reduce the water ow by moving the valve lever on the left-
hand side ofthe oor saw that is connected to the water hose.
INFORMATION
You can turn the water on and o and adjust the water ow from either side of the oor
saw, asrequired.
▶When you have nished cutting, turn o the water supply to the blade guard, turn o the
water supply at the source, and detach the water source hose from the oor saw.
▶Drain the water from the radiator of the upper transmission.
INFORMATION
Pay attention to the engine manufacturer's instructions.
Automatic water system (AWS)
The automatic water system has a solenoid valve in the water supply system, which works
inconjunction with the "Zero saw blade" option on the control panel. When the saw blade
is "zeroed" on the top of the surface, the solenoid valve allows water to ow when the
blade is plunged into a cut. When the saw blade is lifted out of the cut and passes the
"zero point", thewater ow is automatically switched o.
INFORMATION
When using AWS, adjust the lever of the water valve so that the water ow is measured.
AWSautomatically turns the water on/o when the saw blade enters or exits the cut.

Battery
DANGER
Death or serious injury from the battery!
Ignitable, explosive gas escapes from the battery. Do not expose the battery to sparks or
naked ames, and keep the area around the battery well ventilated.
Disconnect the battery before servicing the oor saw. Always keep the battery cable
clamps away from the battery terminals while the battery is disconnected. Take care to
always connect the battery cables to the correct terminal when reconnecting.
Battery (diagram)
INFORMATION
Use a suitable battery tester to check the battery strength.
Wear protective goggles or face protection and avoid contact with the skin when handling
and servicing the battery.
The oor saw contains a charged battery with a positive cable (red) and a negative cable
(black).
Battery maintenance
Proceed as follows:
Detach the battery from the holder
▶Disconnect the negative cable (black) from the negative terminal.
INFORMATION
Always disconnect the negative cable rst.
▶Disconnect the positive cable (red) from the positive terminal.
▶Remove the battery.
▶When cleaning the battery, inspect the terminals, clamps and cables for damage and
corrosion. Clean the poles and terminals with a wire brush. Grease the battery terminals
and poles with acid-free, acid-resistant grease.
▶Carefully reinsert the battery in the battery box.
▶Reconnect the positive cable.
INFORMATION
▶Always reconnect the positive cable (red) rst.
▶Reconnect the negative cable (black).
▶Place the battery compartment cover on the two screws of the pull rod and tighten with
the two ratchet knobs.

Handle adjustment
INFORMATION
The length and height of the handles can be adjusted to an ergonomic position.
The handlebars help you to guide and manoeuvre the oor saw. Move the handlebars to
the desired position for better leverage when lifting and steering. To manoeuvre the oor
saw forwards and backwards, turn on the freewheel switch and move the oor saw as
desired.
The freewheel only works when the ignition key is turned to ON.
Handle adjustment (diagram)
Adjusting the handlebar
▶Undo the handlebar adjustment lever.
▶Move the handlebar forwards or backwards to adjust the length, then tighten the
adjustment lever once more.
▶Press the pushbutton on the side of the steering handle for inclining the guide bar, and
move the guide bar up or down to adjust the angle.
