Never attempt to modify the controls or safety devices.

Electrical connection.

Reduce the risk of electric shock:

• Voltage and frequency of the machine (see rating plate) and the voltage and frequency of your power supply must be the same.
• Examine the connecting cord, power plug and extension cord for damage. Damaged cords, couplings and plugs or connecting cords that do not comply with the regulations must not be used
• Only connect electrical connector to a properly installed wall outlet.
• Only use extension cords that comply with the regulations for the intended application.
• Check that the insulation of the connection cable, extension cord, plug and coupling is in good condition.

Position the connection cable and extension cord correctly:

• Check minimum cross section of wires (wire gauge) – see “Connecting to Power Supply”.
• To reduce the risk of stumbling, position and mark the connecting cord so that it cannot be damaged or endanger others.
• Using unsuitable extension cords can be dangerous. Only use extension cords that are approved for outdoor use, are appropriately labeled and have a sufficient cable cross-section.
• The plug and coupling of the extension cord must be waterproof or routed in such a way that they cannot come into contact with water
• the plug and coupling of the extension cord must not be immersed in water.
• Do not allow cord to rub on edges or pointed or sharp objects.
• don’t trap or squeeze the cord in or under doors or windows
• If cords are twisted – unplug the power tool and straighten them out
• Always unwind the extension cord completely from the cable reel to reduce the risk of fire from overheating.

While Working

 If the power cord is damaged, immediately disconnect the plug from the wall outlet to avoid the risk of electric shock.

Avoid damage to the power supply cord. Do not drive over it, pinch or tug it.

Never pull the connection cable to disconnect it from the wall outlet. To unplug, grasp the mains plug, not the cable.

Only touch the mains plug, connection cable and extension cord and electrical plug connections with dry hands.

Never spray electrical devices with water – Danger of a short circuit!

 To reduce the risk of a short circuit or electrocution, never work with the vacuum cleaner in the rain or in wet or very damp locations!

In the event of imminent danger or in an emergency – move switch to 0 .

Never leave a running unit unattended.

Do not leave the unit outdoors in the rain.

Only operate the unit while standing. Do not cover the unit; ensure adequate motor ventilation.

Only vacuum with undamaged filter element.

If foam develops or liquid leaks, end work immediately, pull mains plug and empty tank.

If the unit is subjected to unusual stress for which it was not designed (e.g., heavy impact or a fall), always check that it is in safe operating condition before continuing work – see also “Before Starting Work”. Make sure the safety devices are working properly. Do not continue operating the machine if it is damaged. In case of doubt, contact a dealer.

Before leaving the unit unattended: Turn it off and disconnect the mains plug.

After Finishing Work

Disconnect the mains plug from the wall outlet.

Never jerk the connecting cord to disconnect it from the wall outlet. To unplug, grasp the plug, not the cord.

Always clean dust and dirt off the unit – do not use any grease solvents for this purpose.

Maintenance and repairs

WARNING

 Before starting any work on the machine: Always disconnect the machine from the mains power supply.

• Use only high-quality spare parts. Otherwise, there may be a risk of accidents and damage to the unit. If you have any questions in this respect, consult a servicing dealer.
• To avoid risks, work on the machine (e. g. replacing a damaged connecting cord) may only be carried out by authorized dealers or qualified electricians.

Clean plastic parts with a cloth. Harsh detergents may damage the plastic.

Clean ventilation slots in motor housing as needed.

The machine must be serviced regularly. Do not attempt any maintenance or repair work not described in the Instruction Manual. All other work should be carried out by a servicing dealer.

STIHL recommends the use of genuine STIHL spare parts. Such parts have been optimized for the machine and the user’s requirements.

STIHL recommends that maintenance and repair work be carried out only by authorized STIHL dealers. STIHL dealers receive regular training and are supplied with technical information.

Lock the machine in position

Apply the brake on the caster to lock the machine in a particular position.

Assembling the Unit

Various accessory parts must be mounted on the machines before starting for the first time.

WARNING
Do not plug the power cord into the outlet until the machine is completely assembled.

• Release the latches (1)

• Lift the upper part of the vacuum cleaner (2) vertically up and off

• Remove the accessories from the container

• Push filter bag sleeve onto intake port as far as possible (see instructions on filter bag)

• Refit the upper part of the vacuum cleaner (2) and close the latches (1)
  – ensure that the latches engage properly

• Push the suction hose into the connector

• Push the handle tube (3) into the sleeve of the suction hose

• Push extension tube (4) onto the handle tube

To connect other tools (e. g., grinding machine):

• Fit adapter for power tools (5) (supplied with the model SE 122 E) to suction hose instead of handle tube

• Mount extension tube holder at a distance (A) of approx. 20 cm from the bottom edge of the extension tube

• Depending on the intended use of the vacuum, fit the crevice tool (6), all-purpose tool (7) or floor tool (8) onto the extension tube.

Connecting to Power Supply

The voltage and frequency of the machine (see rating plate) must match the voltage and frequency of the power connection.

The minimum fuse protection of the power connection must comply with the specifications – see “Specifications”.

The machine must be connected to the power supply via an earth-leakage circuit breaker to disconnect the power supply if the differential current to earth exceeds 30 mA.

The power connection must correspond to IEC 60364 and relevant national regulations.

Extension Cords

Make sure your electrical cord set is in good condition and suitable for outdoor use. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized extension cord may cause a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size (AWG) to use for your machine (Cord types SJW or SJTW) depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Appropriate extension cords are available in special stores for electrical equipment or from your STIHL dealer.

Working

Vacuuming dry materials

WARNING
Flammable materials must not be vacuumed.

Always make sure that the filter bag has been fitted in the container before vacuuming dry materials. The vacuumed material can then be disposed of without difficulty. Dry materials can also be vacuumed without filter bag.

NOTICE
Never use the vacuum cleaner with a damaged filter element or without the filter element.

Vacuuming liquids

WARNING
Flammable liquids must not be vacuumed.

Always remove the filter bag and check operation of the float before vacuuming liquids. The float switches off the air stream when the container is full. If the machine is exclusively used for wetvacuuming, the filter element should be replaced by a special insert (special accessory).

The filter element is damp after vacuuming liquids. The filter element is likely to clog up more quickly if dry material is vacuumed while it is still damp. For this reason, the filter element should be dried or replaced by a dry filter element before vacuuming dry materials.
