Safety Information
ALWAYS guide the saw in such a way that the operator is not
squeezed between the saw and solid objects. Special care is
required when working on uneven ground or when compacting
coarse material. Make sure to stand firmly when operating the
machine under such conditions.
ALWAYS operate the saw in such a way that there is no danger
of it turning over or falling in, when working near the edges of breaks,
pits, slopes, trenches and platforms.
ALWAYS store equipment properly when it is not being used.
Equipment should be stored in a clean, dry location out of the reach
of children.
ALWAYS close fuel valve on engines equipped with one when
machine is not being operated.
ALWAYS operate machine with all safety devices and guards in place
and in working order. DO NOT modify or defeat safety devices. DO
NOT operate machine if any safety devices or guards are missing or
inoperative.
2.2 Operator Safety while using Internal Combustion Engines
Internal combustion engines present special hazards during
operation and fueling! Read and follow warning instructions in engine
owner’s manual and safety guidelines below. Failure to follow
warnings and safety guidelines could result in severe injury or death.
DO NOT smoke while operating machine.
DO NOT smoke when refueling engine.
DO NOT refuel hot or running engine.
DO NOT refuel engine near open flame.
DO NOT spill fuel when refueling engine.
DO NOT run engine near open flames.
DO NOT run machine indoors or in an enclosed area such as an
enclosed room unless adequate ventilation, through such items as
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.
ALWAYS refill fuel tank in well-ventilated area.
ALWAYS replace fuel tank cap after refueling.
ALWAYS check fuel lines and fuel tank for leaks and cracks before
starting engine. Do not run machine if fuel leaks are present or fuel
lines are loose.

Safety Information
2.3 Service Safety
Poorly maintained equipment can become a safety hazard! In order
for the equipment to operate safely and properly over a long period of
time, periodic maintenance and occasional repairs are necessary.
DO NOT attempt to clean or service machine while it is running.
Rotating parts can cause severe injury.
DO NOT operate machine without air cleaner.
DO NOT remove air cleaner cover, paper element, or precleaner
while engine is running.
DO NOT alter engine speeds. Run the engine only at speeds
specified in the Technical Data Section.
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.
DO NOT test for spark on gasoline-powered engines, if engine is
flooded or the smell of gasoline is present. A stray spark could ignite
fumes.
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.
ALWAYS replace safety devices and guards after repairs and
maintenance.
ALWAYS keep area around muffler free of debris such as leaves,
paper, cartons, etc. A hot muffler could ignite them, starting a fire.
ALWAYS do Periodic Maintenance as recommended in Operator’s
Manual.
ALWAYS clean debris from engine cooling fins.
ALWAYS replace worn or damaged components with spare parts
designed and recommended by Wacker.
ALWAYS disconnect spark plug on machines equipped with gasoline
engines, before servicing, to avoid accidental start-up.
ALWAYS keep machine clean and labels legible. Replace all missing
and hard-to-read labels. Labels provide important operating
instructions and warn of dangers and hazards.
ALWAYS follow instructions when disconnecting fuel lines. Failure to
do so may result in fuel squirting from fuel system.

Safety Information
2.4 Hazard Symbols
Symbol Meaning
EXPLOSIVE FUEL
Gasoline is extremely flammable and its vapors can explode if ignited.
Store gasoline only in approved containers, in well-ventilated, unoccupied
buildings, away from sparks or flames. Do not fill the fuel tank while the
engine is hot or running, since spilled fuel could ignite if it comes in contact
with hot parts or sparks from ignition. Do not start the engine near spilled
fuel. Never use gasoline as a cleaning agent.
HOT PARTS
Engine components can get extremely hot from operation. To prevent severe
burns, do not touch these areas while the engine is running or immediately
after it is turned off. Never operate the engine with heat shields or guards
removed.
OVER SPEED
Never tamper with the governor components or settings to increase the
maximum speed. Severe personal injury and damage to the engine or
equipment can result if operated at speeds above maximum.
ACCIDENTAL STARTS
Before servicing the engine or equipment, always remove the key and
disconnect the spark plug lead to prevent the engine from starting
accidentally. Ground the lead to prevent sparks that could cause fires. Make
sure the equipment is in neutral.
ROTATING PARTS
Keep hands, feet, hair, and clothing away from all moving parts to prevent
injury. Never operate the engine with covers, shrouds, or guards removed.
LETHAL EXHAUST GASES
Engine exhaust gases contain poisonous carbon monoxide. Carbon
monoxide is odorless, colorless, and can cause death if inhaled. Avoid
inhaling exhaust fumes, and never run the engine in a closed building or
confined area.
ELECTRICAL SHOCK
Never touch electrical wires or components while the engine is running. They
can be sources of electrical shock which could cause severe injury or burns.
