which have been approved by STIHL for this machine or technically equivalent parts may be mounted on the machine. Contact a dealer if in doubt. Use only high-quality accessories, in order to avoid the risk of accid ents or dam age to the machine.

STIHL recommends the use of genuine STIHL parts and accessories. These have been opti mized for the product a nd the user's 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.

Physical suitability

The machine may only be operated by people who are fit, in good physical health and in good mental condition. If you have any condition tha t might be aggravated by strenuous work, check with your doctor before operating a machine.

Anyone who has consumed alcohol, medicines affecting their ability to react or drugs must not operate the machine.

If you have a pacemaker: The ignition system of your machine produces an electromagnetic field of very low intensity. An effect on individual pacemaker types cannot be excluded entirely. STIHL recommends that you consult your doctor and the manufacturer of your pacemaker in order to avoid health hazards.

Applications

The high-pressure cleaner can be used to clean motor vehicles, machines, tanks, facades or s tables and to re move rust without dust or sparks.

Other uses are not permitted and may lead to accidents or damage to the machine.

Clothing and equipment

Wear shoes with non-slip soles.

Clothing which c ould becom e trapped i n moving parts of the machine should not be worn. Do not wear a scarf, tie or jewelry when operating the machine. Long hair must be tied up and covered (headscarf, cap, helmet, etc.).

Transporting the machine

Always switch off the engine. Do not touch any hot parts of the

machine, in particular the muffle r surface or the gear housing – risk of

burns!

So that the mac hin e ca n b e tran sported safely on or in a vehicle, it must be secured with stra ps so that it canno t slip or tip over and to protec t it from d amage and prevent fuel spills.

Antifreeze is recommended if the machine and accessories are to be transported at temperatures near or below 0° C (32 °F) – see “Storage”.

Refueling

Switch off the engine before refueling. Never refu el the machine while the

engine is still ho t – the fuel may spi ll over – risk of fire!

Open the fuel filler cap carefully so that any excess pressure is relieved gradually and fuel does not splash out.

The machine may only be ref ueled in a well ventilated pl ace. Clean the machin e immediately if fuel is spilled. Change your clothes immediately if they are contaminated with fuel.

Close the filler cap as tightly as possib le after refueling.

This helps reduce the risk of unit vibrations causing an incorrectly tightened filler cap to loosen or come off and spill quantities of fuel.

Check for leaks. Do not st art th e engin e if there is a fuel leak – serious or fatal

burns could result.

Wear goggles and protective clothing. STIHL recommends that a boilersuit be worn in order to reduce the risk of injury due to accidental exposure to the highpressure jet.

Gasoline is an extremely flammable fuel – keep clear of

naked flames and fire – do not spill any fuel – no smoking.

Detergent

Unsuitable detergents can cause damage to health, as well as to the machine and the object to be cleaned. Contact a dealer if in doubt.

STIHL recommends the use of genuine STIHL detergents. Follow the instructions for use.

Chemical detergents may contain physiologically harmful (toxic, caustic, irritant), flammable or explosive substances. Note the manufacturer's

safety data sheets!

Detergents should alwa ys be used in the proportions specified by the manufacturer.

Before starting work

Only connect the hi gh -pres su re c le ane r to the drinking wa ter main in conju nction with a backflow prev enter – see "Special accessories".

Do not use the machine with dirty w ater. If there is a risk that dirty wate r will occur

(e. g., flowing sand), an appropriate water filter must be used.

Check that the high-pressure cleaner is in full working order. Pay particular attention to the high-pressu re hos e, the spray attachment, the safety parts and the fuel system. Note the relevant chapter of the instruction manual:

Inspecting the high-pressure cleaner

The high-pressure cleaner should only be used if it is in ful l working order – risk

of accident! – It must be possible to move the

switch to the 0 position easily

– Check that the spark plug boot is

secure. A loose boot can lead to flying sparks which may ignite the escaping fuel/air mixture – risk of

fire!

– Inspect the high-pressure hose,

spray attachment and safety mechanis ms for damage

– High-pressure hose and spray

attachment in good condition (clean, moving easi ly) and corr ectly assembled

– For good control of the machine, the

handles should be clean and dry with no oil or dirt on them

– Check the oil level – Never attempt to modify the controls

or safety devices

Starting the engine

Start the engine as described in the engine manual.

Move at least 3 meters away from the place at which the machine was refueled and never start the ma chine in e nclosed spaces.

Place the machine on a flat surface and ensure a firm and safe footing.

The machi ne is operated by only one person. There should not be any other person within the work ing area, not even when starting the machine.

Check that the speed drops: the engine must idle when the operator releases the trigger on the spray gun.

During work

Ensure you always have a firm and safe footing.

Beware of slipping on ice , wate r, snow or uneven ground!

Keep the high-pressure cleaner as far away as possible from the object being cleaned. Keep the ma ch ine at least 1 m away from buildings while working.

Switch off the engine imme diately in th e event of imminent danger or in an emergency.

Do not connect the highpressure cleaner directly to the drinking water main.

Never direct the highpressure jet or water hose against electrical appliances and equipment – danger of short-

circuiting!

Never direct the highpressure jet or water hose against electrical equipment, connections and power c ables – dan-

ger of short-circuiting!

Never direct the highpressure jet against yourself or other people, not even to clean clothing or shoes – risk of injury!

RB 302, RB 402 PLUS

English

Do not direct the high-pressure jet against animals.

Do not direct the high-pressure jet onto places you cannot see.

Children, animals and bystanders must remain at a distance.

Hazardous substances (e. g ., asbestos or oil) must not be allowed to escape into the environment unchecked when working with the machine. The applicable environmental regulations must be observed without fail.

Surfaces of asbestos cement must never be cleaned with a high-pressu re jet. Hazardous, breathable asbestos fibers may be relea sed in addition to the dirt. The danger is greatest when the washed surface has dried.

Never draw in fluids containin g solvents or undiluted acids and solvents (e. g., gasoline, heating oi l, paint thinne r or acetone). These substan ces damage the materials used in the machine. The spray is highly combustible, explosive and poisonous.

Delicate parts made of rubber, fabric or sim ilar material s must not be cle aned with a pencil jet, e. g., from the rotary nozzle. Maintain a sufficient distance between the high-pres sure hose and the surface when cleaning to avoid any damage to the surface being cleaned.

The trigger on the spray gun mu st move easily and automatically return to its starting position when released.

Always hold the spra y attachm ent firmly with both hands on th e handles in orde r safely to withstand the kickback force

and additional torque produced when using spray attachments with an angle d spray lance.

Ensure that the high-pressure hose is not damaged by being driven over, squashed or pulled; protect it against heat and oil.

The machine must not be covered. Ensure that the engine is cooled sufficiently.

Ensure proper ventil ation w hen wo rking in trenches, hollows or other confined locations – risk of serious or fatal

injury from breathing toxic fumes!

If you feel si ck, if you have a he ada ch e, vision problems (e.g., your field of vis ion gets smaller), hearing problems, dizziness or inability to concentrate, stop work immediately. Such symptoms may be caused by an excessively high concentration of exhaust emissions –

risk of accident!

No smoking when working with or near the machine - risk of fire! The f uel ta nk may give off inflammable vapors.

Safety equipment

When the safety equipmen t 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

If the machine is sub jec te d to u nus ua lly high loads for which it w as not de signed (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 worki ng prop erl y. Never use the ma chine if it is not in good condition. Consul t a servicing dealer if i n doubt. STIHL recommends STIHL servicing dealers.

Before leaving the machine: – Switch off machine – Disconnect water intake hose

between machine and water supply

Maintenance and repairs
