1.1 Laws Pertaining to Spark Arresters

Notice: State Health Safety Codes and Public Resources Codes

specify that in certain locations spark arresters be used on internal
combustion engines that use hydrocarbon fuels. A spark arrester is a
device designed to prevent accidental discharge of sparks or flames
from the engine exhaust. Spark arresters are qualified and rated by
the United States Forest Service for this purpose.

In order to comply with local laws regarding spark arresters, consult
the engine distributor or the local Health and Safety Administrator.

exhaust fans or hoses, is provided. Exhaust gas from the engine
contains poisonous carbon monoxide gas; exposure to carbon
monoxide can cause loss of consciousness and may lead to death.

1.3.8 Refill the fuel tank in a well-ventilated area.

1.3.9 Replace the fuel tank cap after refueling.

1.3.10 ALWAYS check the fuel lines and the fuel tank for leaks and cracks
before starting the engine. Do not run the machine if fuel leaks are

1.4 Service Safety

A poorly maintained machine can become a safety hazard! In order
for the machine to operate safely and properly over a long period of
time, periodic maintenance and occasional repairs are necessary.

WARNING

1.4.1 Do not attempt to clean or service the machine while it is running.
Rotating parts can cause severe injury.

1.4.2 Do not crank a flooded engine with the spark plug removed on
gasoline-powered engines. Fuel trapped in the cylinder will squirt out
the spark plug opening.

1.4.3 Do not test for spark on gasoline-powered engines if the engine is
flooded or the smell of gasoline is present. A stray spark could ignite
the fumes.

1.4.4 Do not use gasoline or other types of fuels or flammable solvents to
clean parts, especially in enclosed areas. Fumes from fuels and
solvents can become explosive.

1.4.5 Keep the area around the muffler free of debris such as leaves, paper,
cartons, etc. A hot muffler could ignite the debris and start a fire.

1.4.6 Replace worn or damaged components with spare parts designed and
recommended by Wacker Neuson Corporation.

1.4.7 Disconnect the spark plug on machines equipped with gasoline
engines, before servicing, to avoid accidental start-up.

1.4.8 Keep the machine clean and labels legible. Replace all missing and
hard-to-read labels. Labels provide important operating instructions
and warn of dangers and hazards.

3. Operation

3.1 Recommended Fuel

The engine requires regular grade unleaded gasoline. Use only fresh,
clean gasoline. Gasoline containing water or dirt will damage fuel
system. Consult engine owner’s manual for complete fuel
specifications.

3.2 Application

The Floorsaw should only be operated in a forward direction. The drive
engine fastened to the frame drives the cutting blade by way of a drive
belt.

The infinitely variable cutting depth of the cutting blade is adjusted with
the help of a hand crank, and 1 turn of the crank equals 5 mm (0.20 in)
cutting depth adjustment.

The Blade guard can be swung away upwards for an easier assembly
of the cutting blade.

The blade guard is moreover linked to the water tank via a hose and a
coupling.

Wetting the cutting blade with water will stop dust forming during the
cutting process.

The coupling fitted to the water hose means an external water supply
can be used.

The engine works according to the 4-stroke principle, is started by
means of a recoil starter, takes in the air via a dry air filter and is air
cooled.

The engine speed can be infinitely varied with the help of the throttle
lever; the optimum cutting speed of the cutting blade is only achieved
when the drive engine is turning at full speed.

In order to facilitate the starting, the engine is provided with a choke.

During operation, there should always be sufficient water in the water
tank

BFS 614B Operation

3.7 Use of Cutting Blade

3.7.1 General application instructions for use of diamond cutting
blades:

3.7.1.1 Never use a diamond cutting blade of a diameter larger than

necessary to cut down to a certain depth.

3.7.1.2 Pull the blade out of the cut if it has stopped turning and

before restarting the engine. Check to see if the belt has
been tensioned sufficient if the cutting blade should get
stuck in the cut. Also check the tensioning screw and make
sure that it is correctly tightened.

3.7.1.3 Always cut a straight line. Mark the line clearly allowing the

operator to follow it easily without having to guide it from
one side to the other to come back to the line (do not cut
narrow curves).

3.7.1.4 Sufficient drive power is essential, therefore always cut with

engine at full throttle.

3.7.1.5 Never exceed the maximum turning speed (printed on

cutting blade).

3.7.1.6 Only use appropriate cutting blade for the material you are

going to cut. Wacker has an extensive selection of diamond
blades in different grades of qualities for you.

Diamond blades for asphalt are suited for:

Asphalt

Freshly mixed concrete (from 48 hours to 28 days old)

Sandstone

Sandy bricks

Floor toppings

Sandy limestone

Not suited for:

Set concrete

Hard bricks or paving setts

Concrete with exposed aggregates by washing

Natural stone

Diamond blades for concrete are suited for:

Not suited for:

wpm_tx001178gb.fm 19

Set concrete (older than 28 days with reinforcements up to
maximum diameter of 6mm)

Other kind of materials

Operation BFS 614B

DO NOT cut into the crushed stone layer or similar material layer when
working with a diamond blade. Uneven wear may occur when cutting
along road edges or two different types of materials (cutting along
joints). Special care is required if the material to be cut shows
irregularities (eg. reinforcement bars). This could easily lead to an
overloading of the cutting blade. Proceed carefully when starting a cut.
Lower the blade into the material slowly.

CAUTION: Special care is required when working on slopes (lanes and
surfaces). Make sure the machine is not exerting a lateral pressure on
the blade.

3.7.2 Installation of Cutting Blade:

See Graphic: wpmgr006728

3.7.2.1 Make sure that the engine is switched "OFF".

3.7.2.2 Turn the crank (a) counter-clockwise until the machine tilts
up at maximum height.

3.7.2.3 Fold up blade-guard (b) from the front side.

3.7.2.4 Using the wrench that comes with the machine, remove the
screw (c) which fastens the face-plate (d).

3.7.2.5 Take out the face-plate (d), and then place the blade (e)
through the shaft next to the supporting disc (f).

3.7.2.6 Then re-install the face-plate (d) and secure by tightening
the screw (c).

"OFF", and the blade is cool.

3.7.3.2 Turn the crank (a) counter-clockwise until the blade no
longer touches the floor.

3.7.3.3 Fold up blade-guard (b) from the front side.

3.7.3.4 Loosen & remove the screw (c), and then remove the face­plate (d) and the blade (e) from the shaft.

3.7.3.5 Fold down the cutting blade guard.

NOTE: Store the face-plate, screw and the cutting blade in such a way
as to avoid them getting dirty. Assemble these parts back before
transport of the machine.

Operation BFS 614B

3.8 Converting the cutting blade position

See Graphic: wpmgr006731

You can change the position of the cutting blade guard together with
the guide wheel to use the cutting blade on the left side.

Proceed as follows for the conversion of the blade position:

3.8.1 Disassemble the cutting blade as described in section “Removal of
Cutting Blade”.

3.8.2 Disassemble the cutting blade guard (a). Loosen three screws (b).

3.8.3 Disassemble the cover weldment (c). Loosen two screws (d).

3.8.4 Loosen the two screws (e) on the bearing flange.

3.8.5 Disassemble the guide wheel assembly (f) by removing the screw (g),
bushing (h), two locknuts (i), and two washers (j).

Note: When positioning the guide wheel on any of the sides of the
machine. Apply same orientation of its hardwares.

3.8.6 Assemble the guide wheel, cutting blade guard, cover weldment and
two screws from the bearing flange on their opposite position.
