4 Safety Precautions
■ If the water pump changes or starts to behave
differently when working, it may not be in safe
condition. This may result in serious injury to
people and damage to property.
► Stop working and consult a STIHL special‐
ist dealer.
■ Water can freeze on the floor and in compo‐
nents of the water pump at temperatures
below 0 °C. This may result in the user slip‐
ping, falling and becoming seriously injured. It
may also result in damage to property.
► Do not use the water pump at temperatures
below 0 °C.
■ If the suction hose or pressure hose is pulled,
the water pump may move and fall over. This
may result in damage to property.
► Do not pull on the suction hose or pressure
hose.
■ If the water pump is placed on a sloping,
uneven or unpaved surface, it may move and
fall over. This may result in damage to prop‐
erty.
► Place the water pump on a horizontal, level
and paved surface.
► Secure the water pump so it cannot move.
■ Taking in highly inflammable and explosive liq‐
uids may cause fires and explosions. This may
result in serious or fatal injury to people and
damage to property.
► Do not take in or discharge highly inflam‐
mable or explosive liquids.
■ Taking in irritating, corrosive and toxic liquids
may endanger health and damage compo‐
nents of the water pump. This may result in
serious or fatal injury to people and damage to
property.
► Do not take in or discharge irritating, corro‐
sive or toxic liquids.
■ The water pump is not sterile or food-safe. If
liquid food products are taken in, they will be
contaminated.
► Do not take in or discharge liquid food prod‐
ucts.
■ If the water pump is not filled with water before
starting the engine, this may result in damage
to the water pump.
► Fill the water pump with water before start‐
ing the engine.
■ If the suction strainer is not attached, objects
may be sucked into the water pump. The
water pump may become clogged or dam‐
aged.
