Fit the filled water tank to the saw carriage only
j)
after fitting the saw to the saw carriage. This will
prevent the saw carriage falling over.
k) Concealed electric cables or gas and water pipes
present a serious hazard if damaged while you
are working. Accordingly, check the area in which
you are working beforehand (e.g. using a metal
detector). External metal parts of the machine may
become live, for example, when an electric cable is
damaged accidentally.
l) Don't work from a ladder.
m) Don't work above shoulder height.
n) If the work involves breaking right through, take
the appropriate safety measures at the opposite
side. Parts breaking away could fall out and / or fall
down and injure other persons.
o) When using the wet cutting technique, take care
to ensure that the water drains away in controlled
fashion and check that the water or water spray
presents no hazard and causes no damage to the
surrounding area.
p) Secure the area below the working area.
5.3 Thermal
a) Wear protective gloves when changing cutting
tools as they get hot during use.
b) The exhaust system and motor get very hot. Always
hold the machine securely with both hands on the
grips provided.
5.4 Liquids (gasoline and oil)
a) Store gasoline and oil in a well-ventilated room in
fuel containers in compliance with regulations.
b) Allow the machine to cool before refueling.
c) Use a suitable funnel when refueling.
d) Don't use the gasoline or other flammable liquids
for cleaning.
e) Don't refuel the machine at the workplace.
f) When refueling, take care to avoid spillage of
gasoline.
5.5 Sawing slurry
Avoid skin contact with sawing slurry.
5.6 Vapors
a) Don't smoke when filling the tank with fuel!
b) Avoid inhaling gasoline vapors and exhaust
fumes.
c) Hot exhaust gases containing sparks or sparks gen-
erated by the cutting operation may cause fire or
explosion. Take care to ensure that the sparks
generated do not ignite flammable (gasoline, dry
grass, etc.) or explosive (gas, etc.) substances.
5.7 Dusts
a) Large quantities of dust hazardous to the health are
generated when cutting (especially when dry cutting).
The operator and bystanders must wear suitable
dust masks while the machine is in use.
b) Dust or vapors containing chemical substances may
be generated when working on unknown materials.
These substances could cause serious damage to
the health. Obtain information about hazards pre-
sented by the materials from the client or the
authorities responsible. The operator of the ma-
chine and any bystanders must wear respiratory
protection that is approved for use in conjunction
with the applicable substance.
c) To reduce the amount of dust generated when
cutting mineral materials and asphalt, we recom-
mend use of the wet cutting technique.
d) WARNING: Some dust created by grinding, sand-
ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res-
piratory or other injury. Some examples of these
chemicals are: lead from lead-based paints, crys-
talline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated lumber. Your risk from these
exposures varies, depending on how often you do
this type of work. To reduce exposure to these
chemicals, the operator and bystanders should
work in a well-ventilated area, work with ap-
proved safety equipment, such as respiratory pro-
tection appropriate for the type of dust generated,
and designed to filter out microscopic particles
and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protec-
tive clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth,
nose, eyes, or to remain on your skin may promote
absorption of harmful chemicals.
5.8 Requirements to be met by users
a) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
b) Stay alert, watch what you are doing and use com-
mon sense when operating the machine. Don't
use the machine when you are tired or under the
influence of drugs, alcohol or medication. A mo-
ment of inattention while operating machines may
result in serious personal injury.
