2. Safety information
for floor saws with combustion engine drive
2.1 General instructions
2.1.1 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 floor saws and have proved their
abilities to the employer and
∗ may be expected to carry out the job they are charged with carefully.
They must have been assigned to work on the floor saws by the company.
2.1.2 Floor saws may only be operated taking the operator's manual of the
manufacturer and this safety information into account.
2.1.3 The persons charged with the operation of floor saws must 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.
2.1.4 This machine generates noise that exceeds the country-specific permissible noise levels (individual rating level). It may therefore be necessary to wear ear protection.
2.2 Operation
2.2.1 The function of operation levers or elements must not be influenced or
rendered ineffective.
2.2.2 Use only cutting blades that are suitable for the peripheral speed or the
speed of the machine.
2.2.3 Always use the correct cutting blade for the material to be cut.
2.2.4 Do not touch hot parts as they can cause burns!
2.2.5 Particularly when starting the engine you have to make sure that the
cutting blade does not come into contact with anything.
2.2.6 Never let the machine run unattended.
2.2.7 The operator must not leave the machine during operation.
2.2.8 Before the operator leaves the floor saw unattended, he must switch
off the engine and take precautions to prevent the machine from
slipping or falling over.
Safety information
SV00075en.fm 9
2.2.9 Open flames and smoking are strictly prohibited in the immediate
vicinity of this machine.
2.2.10 The tank lid must be tightly secured. When the motor is switched off,
the fuel tap - if there is one - must be closed. When transported over
long distances, the tank of gasoline or mixed gasoline driven engines
must be completely emptied.
Leaking fuel tanks can lead to explosions and therefore must be replaced immediately.
2.2.11 The tank may only be filled when the motor is switched off and the fuel
must not make contact with hot parts or fall on the ground.
2.2.12 Safety in the work area
There may be no electric lines, gas lines, water lines or pipes in the
work area.
2.2.13 No operation in closed quarters
Do not operate the machine in closed quarters!
In partially closed rooms such as tunnels, drifts or deep trenches, ensure sufficient ventilation by, for example, providing a powerful exhaust
air fan.
Danger of poisoning! Do not inhale exhaust fumes. They contain toxic
carbon monoxide that can lead to unconsciousness or death.
2.2.14 Floor saws must be operated in wet-cutting operation to prevent
harmful particulate matter from developing. During wet-cutting
operation, a sufficient water supply must always be ensured.
2.2.15 Do not operate this machine in areas where explosions may occur.
2.2.16 Prior to working near easily combustible material, ensure that supplies
of water or a fire extinguisher are readily available for use.
2.2.17 Always wear eye protection, ear protection, working gloves, hard hat,
close-fitting clothing and hard-toed shoes during work. Shoes and leg
wear must not be open in order to protect the wearer from flying
sparks. In the case of dusty ambient air, breathing protection must also
be worn.
2.2.18 Prevent the machine from turning to the side in the case of cuts,
thrusts, blows or falls. Otherwise, the cutting blade may be damaged.
Only cut materials on the edge of the blade.
2.2.19 Prior to commissioning, fix the protective hood in protective position.
2.2.20 During work, no one is to come near the machine.
2.2.21 Prior to making adjustments, the operator must stop the cutting blade.
2.2.22 Work in a calm and composed manner. Prevent risks to others by
exercising caution.
2.2.23 Do not process loose materials (e.g. paving stones).

2.3 Safety checks
2.3.1 Floor saws may only be operated with all safety devices installed.
2.3.2 Before starting operation, the operator has to check that all control and
safety devices are functioning properly.
2.3.3 Prior to starting the cutting operation, the following have to be checked
on a daily basis:
∗ Proper condition of the cutting blade.
∗ Tightness of the cutting blade.
∗ Damage and wear of the operating and safety equipment.
2.3.4 If defects on the safety devices or other defects impairing the
operational safety of machine are observed, the supervisor must be
informed immediately.
2.3.5 If there are defects jeopardizing operational safety, the machine has to
be switched off immediately.
Safety information
SV00075en.fm 11
2.4 Maintenance
2.4.1 Only use original spare parts. Alterations to this machine, incl. adjustments of the maximum engine speed set by the manufacturer may only
be carried out with the express permission of Wacker Neuson. In case
of non-observance, all liability shall be refused.
2.4.2 Switch off the motor during maintenance work and remove the spark
plug terminal cap (if there is one), in order to avoid an unintentional
start. This procedure may only be waived if the work cannot be carried
out when the motor is switched off.
2.4.3 Exercise caution when checking the ignition system. The electronic
ignition creates a very high voltage.
2.4.4 As soon as maintenance and repair jobs have been completed, all
safety devices must be properly reinstalled.
2.4.5 It is not permitted to tilt the machine for maintenance work.
2.4.6 In order to prevent malfunctions, the floor saw should be cleaned using
water after each use.
2.5 Transport
2.5.1 Prior to transport, the cutting blade must be removed and the floor saw
must be put in the lowest cutting position.
2.5.2 For the loading and transportation of floor saws with hoisting gear,
suitable sling chains must be secured at the relevant fixing point.
2.5.3 Loading ramps must be able to bear the load and be in a stable
position. Make sure that no one can be endangered if the machine
slips away or tips over, or if machine parts suddenly move upward or
downward.
2.5.4 When floor saws are being transported in vehicles, precautions have
to be taken to ensure that they do not slip and fall over.
2.6 Maintenance checks
2.6.1 According to the conditions and frequency of use, floor saws must be
checked for safe operation at least once a year by skilled technicians,
such as those employed by Wacker Neuson service stations, and
repaired if necessary.
Please observe the appropriate rules and regulations valid in your country.
