Stihl Re 118 Instruction Manual

							Cleaning Systems Safety ManualEnglish
9 Hold the spray attachment firmly with 
both hands in order safely to withstand 
the kickback force and additional torque 
produced when using spray 
attachments with angled spray lance.
Ensure that the power cable and the 
high-pressure hose are not damaged by 
being driven over, squashed or pulled; 
protect them against heat and oil.
Do not touch the power cord with the 
high-pressure jet.
Safety equipment
When the safety equipment is activated, 
excessive pressure is returned to the 
intake side of the pump via a safety 
valve. This safety feature has been set 
by the manufacturer and must not be 
adjusted.
After finishing work
Never unplug the power plug by pulling 
on the cord: always grip the plug itself.
If the machine is subjected to unusually 
high loads for which it was not designed 
(e. g., heavy impact or a fall), always 
check that it is in good condition before 
continuing work - refer also to the 
chapter Before starting work.
In particular, make certain that the safety 
mechanisms are working properly. 
Never use the machine if it is not in good 
condition. Consult a servicing dealer if in 
doubt. STIHL recommends STIHL 
servicing dealers.Before leaving the machine:
–Switch off machine
–Unplug the power plug from the 
socket
–Disconnect water intake hose 
between machine and water supply
Observe the national safety regulations 
issued, for example, by the employers 
liability insurance association, social 
security institutions, occupational safety 
and health authorities or other 
organizations.
Minors should never be allowed to use 
the machine.
Children, animals and bystanders must 
remain at a distance.
When not using the machine, it must be 
put down in such a way that it does not 
endanger anyone. Ensure that the 
machine cannot be used without 
authorization, unplug the power cord.
The user is responsible for accidents or 
risks involving third parties or their 
property.
Do not let the machine run unattended.
Safety Precautions and 
Working Techniques
Special safety precau-
tions are necessary when 
using this machine. The 
power connection is a 
particular source of 
danger.
It is important that you 
carefully read the entire 
Instruction Manual before 
using the machine for the 
first time and keep it in a 
safe place for future ref-
erence. Non-compliance 
with the Instruction Man-
ual may cause serious or 
even fatal injury. 
						

							Cleaning Systems Safety Manual English
10 The machine should only be provided or 
loaned to people familiar with this model 
and its operation.  The instruction 
manual should always be handed over 
with the machine.
Connect only electric power tools to the 
socket outlet – see Connecting the 
machine to the power supply and 
Operation.
Unsuitable extension cords may be 
dangerous. When working outdoors, 
use only extension cords that are 
approved for this use and 
correspondingly marked and have a 
sufficient cross-section.
Never touch the power plug, power cord 
and extension cord and electrical plug 
connections with wet hands.
Inspect the power cord regularly for 
signs of damage and aging. Never use 
the machine if the power cord is 
damaged – Danger of electrocution!
The machine may only be used when all 
parts are in perfect working order.
Before starting any work on the 
machine, e. g., cleaning, servicing, 
replacement of parts – unplug the 
power plug!
Do not use high-pressure cleaners to 
clean the machine. The hard water jet 
can damage parts of the machine.
Never spray the upper part of the 
vacuum cleaner with water – Danger of 
short-circuiting!
Accessories and spare parts
Only use parts or accessories which 
have been approved by STIHL for this 
machine or which are technically equivalent. Contact a dealer if in doubt. 
Only use high-quality parts and 
attachments. in order to avoid the risk of 
accidents or damage to the machine.
STIHL recommends the use of genuine 
STIHL parts and accessories. These 
have been optimized for the product and 
the users requirements.
Never modify the machine in any way, 
as this could be extremely dangerous. 
STIHL excludes all liability for personal 
injury and damage to property caused 
while using unauthorized attachments.
Applications
Vacuuming of dry, non-flammable 
materials (dust, dirt, broken glass, wood 
or metal shavings, sand, etc.) and non-
flammable liquids (dirty water, spilled 
juices, etc.)
The machine is not suitable for 
vacuuming toxic dust.
Other uses are not permitted and may 
lead to accidents or damage to the 
machine. The machine must not be 
modified in any way – this may also lead 
to accidents or damage to the machine.
Transporting the machine
When transporting the machine in or on 
a vehicle, it must be secured, e.g. with 
straps, so that it cannot slip or tip over.
Do not tilt the machine if there is liquid in 
the container.
Close all latches on the container before 
transport.
Before starting work
Check the machine
The machine should only be used if it is 
in good working order – risk of 
accident!
–It must be possible to move the 
switch to the 0 position easily.
–The switch must b e  i n  t h e  0 position.
Remove the filter bag and check correct 
operation of the float before vacuuming 
liquids or wet materials. Never work 
without the filter element.
Never attempt to modify the controls or 
safety devices
Electrical connection
Minimize the risk of electrical shock:
–Voltage and frequency of the 
machine (see rating plate) must 
match the voltage and frequency of 
the mains supply
–Examine the power cord, power 
plug and extension cord for 
damage. Damaged cords, 
couplings and plugs or power cords 
that do not comply with the 
regulations must not be used Never use the machine to 
vacuum hot materials 
(hot ash, flammable 
explosive dust, glowing 
cigarette butts, etc.) or 
combustible liquids 
(gasoline, thinner, etc.) 
as well as aggressive liq-
uids (acids, lye) – 
Danger of fire or 
explosion! 
						

							Cleaning Systems Safety ManualEnglish
11 –Only connect the machine to a 
correctly installed power socket
–Use only extension cords that 
comply with the specifications for 
the respective application.
–The insulation on the power cord 
and any extension cord, the plug 
and the coupling must be fully intact
Route the power cord and extension 
cord properly:
–Observe the minimum cross-section 
of the individual cords – see 
Connecting the machine to the 
power supply
–Route and mark the power cord so 
that it cannot become damaged and 
no one is endangered – danger of 
stumbling!
–The connector and coupling of the 
extension cord must be waterproof 
or routed in such a way that they 
cannot come into contact with water 
– the connector and coupling of the 
extension cord must not lie in water
–dont let the cord rub against edges 
or pointed or sharp objects
–dont squeeze the cord under doors 
or windows
–if cords become snarled – unplug 
the power plug and unsnarl the cord
–always unroll the power cord from 
the cable drum completely to avoid 
risk of fire due to overheating
During work
Ensure that the power cord is not 
damaged by being driven over, 
squashed or pulled, etc.
Never unplug the power plug by pulling 
on the cord: always grip the plug itself.
The power cord and power plug must 
never be touched with wet hands.
Never spray electrical devices with 
water – Danger of short-circuiting!
In the event of imminent danger or in an 
emergency – move switch to 0 .
Never let the machine run unattended.
Do not leave the machine standing in the 
rain.
The machine may only be operated in an 
upright position. Do not cover the 
machine and ensure adequate motor 
ventilation.
Ensure that the filter element is always 
undamaged.
If foam develops or liquid escapes, stop 
work immediately, unplug the power 
cord, and empty the container.
If the machine is subjected to unusually 
high loads for which it was not designed 
(e.g., heavy impact or a fall), always 
check that it is in good condition before 
continuing work - refer also to the 
chapter Before starting work. Also 
make certain that the safety 
mechanisms are working properly. Never continue using a machine that is 
not in perfect working order. Consult a 
servicing dealer if in doubt.
Before leaving the machine: Switch off 
the machine – unplug the power cord.
After finishing work
Unplug the power plug from the socket
Never unplug the power plug by pulling 
on the cord: always grip the plug itself.
Clean the machine to remove dust and 
dirt – do not use degreasing agents. If the power cord is dam-
aged, unplug it 
immediately – danger of 
electrocution!
