provisions in line with the setup and mode of
operation of the device.
Regulatory authorities may ask to view respective
documentation.
8.2 Regular maintenance
Attention!
Check the torque of the cylindrical head screws at
the new compressor (1) (see chapter
12. Technical Data) after the first 50 and 250
operating hours.
Prior to every start
– Check compressed air hoses for damage and
replace, if necessary.
– Check that all screw fittings are seated securely,
and tighten if necessary.
– Check connection cables for damage, and, if
necessary, have it replaced by a qualified
electrician.
Daily
– Drain the condensed water of the pressure
vessel at the condensate outlet (3).
Every 50 hours of operation
– Clean air filter (9) (see fig. E, page 3).
– Check the oil level of the compressor at the
inspection glass (11), if necessary refill oil. (See
chapter 6.)
– Drain the condensed water at the filter pressure
reducer (16).
Every 250 hours of operation
– Clean air filter (9) or replace (see fig. E, page 3).
– Clean air filter in the filter pressure reducer or
replace. (see fig. D, page 3).
Every 500 hours of operation
– Completely drain the oil at the oil outlet plug (12)
and replace. (See chapter 6.)
– Check V-belt (see fig. F, page 3): Unscrew V-
belt protective grid (14). Check V-belt, retighten
if required or replace. In order to adjust the V-
belt tension, loosen four screws at the foot of
the motor and shift motor. Retighten the screws
at the foot of the motor. Remount the V-belt
protective grid (14).
Every 1000 hours of operation
– Have an inspection carried out in an authorised
service centre. This significantly increases the
service life of the compressor.
8.3 Storage of device
1. Switch off the device and pull mains plug.
2. Depressurise the pressure vessel and all
connected compressed air tools.
3. Drain the condensed water of the pressure
vessel at the condensate outlet (3).
4. Store the device in such a way that
unauthorised persons cannot start it.
5. Do not place the device on its side. Oil might
leak!
Attention!
Do not store the tool outdoors or in damp
conditions without protection.
Danger of frost
Attention!
Frost (< 5 °C) destroys the pump and accessories
as both always contain water! If there is a danger
of frost disassemble pump and accessories and
store in frost-free conditions.
9. Repairs
Danger!
Repair of tools must be carried out by qualified
electricians only!
If you have Metabo devices that require repairs,
please contact your Metabo service centre. See
www.metabo.com for addresses.
You can download a list of spare parts from
www.metabo.com.
10. Environmental Protection
Danger!
The condensed water from the pressure vessel
contains oil residue and /or contaminations
hazardous to the environment. Dispose of the
condensed water in an environmentally-friendly
manner using respective collection sites!
Danger!
The condensed water from the filter pressure
reducer contains oil residues and/or
contaminations hazardous to the environment.
Dispose of the condensed water in an
environmentally-friendly manner using respective
collection sites!
Danger!
Dispose of the old oil from the compressor in an
environmentally-friendly manner using respective
collection sites.
Observe national regulations on environmentally
compatible disposal and on the recycling of
disused machines, packaging and accessories.
Only for EU countries: Never dispose of
devices in your household waste! In
accordance with European Guideline 2002/
96/EC on used electronic and electric equipment
and its implementation in national legal systems,
used devices must be collected separately and
returned for environmentally compatible
recycling.
11. Troubleshooting
Danger!
Prior to all servicing:
Switch machine off. Disconnect the mains plug.
Wait until the device has stopped. Ensure that
there is no more pressure on the device and all
used compressed air tools and accessories.
Leave the device and all used compressed air
tools and accessories to cool down.
Any works other than the ones described in this
chapter, must be carried out only by a qualified
electrician or the service branch in your country.
After to all servicing:
Put back into operation and check all safety
installations. Ensure that there are no tools or
similar at or in the device.
Compressor does not run:
▪ No mains voltage.
– Check cables, plug, outlet and mains fuse.
▪ Mains voltage too low.
– Use only extension cables with sufficient core
cross-section (see chapter 12. Technical
Data). For cold device: Avoid extension cable.
For cold device: Depressurise the pressure
vessel.
▪ Compressor was switched off by pulling the
mains plug while it was running.
– First, switch off the compressor using the ON/
OFF switch (8), then switch on again.
▪ Motor overheated, e.g. due to insufficient
cooling (cooling ribs covered).
– Switch off the compressor using the ON/OFF
switch (8).
– Remedy the cause for overheating. Leave to
cool for about ten minutes.
– Only three-phase motor model: Check motor
protection switch (18) , if required, reset by
pressing it. (see fig. J, page 3).
– Switch on the compressor again using the ON/
OFF switch (8).
Compressor runs without building up
sufficient pressure.
▪ Condensate outlet leaking.
– Ensure that the condensate outlet (3) is
closed.
– Check the seal of the drainage plug, if
required, replace.
▪ Check valve leaking.
– Have check valve serviced in authorised
service centre.
Compressed air tool does not get enough
pressure.
▪ Pressure controller not open enough.
– Open pressure controller (6) further.
▪ Hose connection between compressor and
compressed air tool leaking.
– Check hose connection; if required replace
damaged parts.

Emission values
These values make it possible to assess the
emissions from the device and to compare
different devices. The actual load may be higher or
lower depending on the operating conditions, the
condition of the device or the accessories. Please
allow for breaks and periods when the load is lower
for assessment purposes. Arrange protective
measures for the user e.g. organisational
measures based on the adjusted estimates.
