SAFETY INSTRUCTIONS
SAFETY INSTRUCTIONS FOR THE USE OF FLOOR SAWS
WITH COMBUSTION ENGINE
General instructions
1. Floor saws may only be operated by persons who
* are at least 18 years of age
* are physically and mentally fit for this job
* have been instructed in operating saws and proved their ability for the job to the employer
* may be expected to carry out the job they are charged with carefully.
The persons must be assigned the job of operating joint cutters by the employer.
2. Both the manufacturer’s operating instructions and these safety instructions for floor saws have to be
observed.
3. The persons charged with the operation of floor saws have to be made familiar with the necessary safety
measures relating to the machine. In case of extraordinary uses the employer shall give the necessary
additional instructions.
4. It is possible that these floor saws exceed the admissible sound level of 90 dB (A). Operators must wear
personal hearing protection if the admissible assessment sound level equals or exceeds 90 dB (A).
Operation
1. The functioning of operating levers or elements is not to be influenced or rendered ineffective.
2. Only use cutting blades suited for the circumferential (peripheral) speed or the machine’s rpm’s.
3. Always use cutting blades correctly suited for the materials to be cut.
4. Do not touch hot machine parts – danger of burns!
5. Be especially careful to observe that the cutting blade does not touch anything when starting the engine
or when lifting or putting down the machine.
6. The operator may not leave the machine while it is running.
7. The operator has to switch off the engineof thejoint cutterbefore leaving themachine. Hehas tosecure
the machine against rolling and overturning.
8. Do not smoke or handle open fire near this machine.
9. The tank lid must fit tightly. Shut fuel cock if available when stopping theengine. Forlong distancetransports of machines operated by fuel or fuel - mixtures, the fuel tank has to be drained completely.
☛ATTENTION! Leaky fuel tanks may cause explosions and must therefore be replaced
immediatelly.
10. Stop engine before filling fuel tank. When refilling fuel tank, do not allow fuel to come into contact with
the hot part of the engine or spill onto the ground.
11. Make sure that sufficient fresh air is available when operating cutters with combustion engines in enclosed areas, tunnels, adits and deep trenches.
12. Floor saws must be used in connection with water (wet cutting) in order to avoid the formation of fine
dusts which are injurious to your health. Make sure that the water supply is sufficient during wet cutting.
13. Do not operate this machine in areas where explosions may occur.
14. When working in the vicinity of inflammable materials, always have water or a fire extinguisher handy.

SAFETY INSTRUCTIONS
15. Always wear protective goggles, hearing protection, work gloves, protective helmet, tight-fitting clothing
and safety shoes during operations with the equipment. Shoes and pants must be closed to offer protection against flying sparks. Wear approved respiratory protection (e.g. a mask) if there is a lot of dust
in the air.
16. Avoid lateral twisting or bending of the machine during the cutting process as well as avoiding impacts,
blows or even dropping the machine as this will lead to damages of the cutting blade. Only subject the
cutting blade to radial burdens (loads).
17. Fix protective hood in lowest position before starting engine.
18. No persons are to be in the vicinity of the floor saw, i.e in front of the floor saw during operation.
19. The operator must stop the blade from turning before relocating the machine.
20. Work calmly and cautiously so as not to endanger others.
Safety checks
1. Floor power saws may only be operated if all operating and safety devices are correctly mounted. This
also includes the water tank.
2. Before starting operation, the operator has to check that all control and safety devices function properly.
3. Before starting the cutting applications check daily as follows:
* proper conditions of cutting blade.
* correct tightening of the cutting blade.
4. In case of defects of the safety devices or other defects reducing the operational safety of thefloor saw,
the supervisor has to be informed immediately.
5. In case of defects jeopardizingthe operational safety of the saw, the machine has to be switched offime
diately.
Maintenance
1. Only use original spare parts. Modifications to this machine including the adjustment of the maximum
speed set by the manufacturer are subject to the express approval of Wacker.In case of nonobservance
all liabilities shall be refused.
2. Switch off the motor and remone spark plug cap from spark plug before carrying out maintenance jobs
to avoid unintentional operation of the machine. Deviationsfrom this areonly allowedif themaintenance
jobs require a running motor.
3. Caution when checking the ignition system.The electronicignitio system produces a very hight voltage.
4. As soon as maintenance and repair jobs have been completed all safety devices have to be reinstalled.
5. Tilting the machine for maintenance works is not allowed.
6. Wash down the floor saw with fresh water after each use to avoid malfunctions.
Transport
1. Disassemble and remove the cutting blade and then place the floor saw in the lowest cutting position
before transporting the machine.
2. During transport, loading and unloading of floor saws by means of lifting devices, appropriate slinging
means or hooks have to be used on the lifting points provided for this purpose on the machine.
3. The load - carrying capacity of the loading ramps has to be sufficient and the ramps have to be secure
such that they cannot turn over. Make sure that no one be endangered by machines turning over or slipping or by moving machine parts.
4. When being transported on vehicles floor saws have to be secured against rolling, slipping or overturning.
Maintenance checks
According to the conditions and frequency of use, floor saws have to be checked for safe operation at least
once a year by skilled technicians, such as those found at Wacker-Service-Centers and have to be repaired if
necessary.
Please also observe the corresponding rules and regulations valid in your country.

Description of function
DESCRIPTION
The floor saw should only be operated in a forward direction (see arrow).
The drive engine (2), which is fastened to the frame, drives the cutting disc by way of a drive belt (7).
A hand crank (5) is used to operate the infinitely variable height adjuster on the blade, and 1 turn = 5 mm cutting
depth adjustment. At any time it is also possible to remove or introduce the cutting disc into the material to be
cut by way of the lever (3).
The blade guard (1) can be swung away upwards for easier fixing and removing of the blade.
The blade guard is moreover linked to the water tankvia a hose and a coupling. If water is used with the blade,
this stops dust being created.
The coupling fitted to the water hose means an external water supply can be used.
A parking brake (6) has been included in the lower, right section of the console. The brake guarantees a safe
parking of the floor saw on upward or downward slopes or gradients.
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 colled.
The revs on the engine can be infinitely varied using the throttle control lever (4); the optimum cutting speed of
the blade is only achieved with the engine working at full load.
In order to facilitate the starting, the eingine is provieded with a choke.
