Start-Up And Use; Maintenance - Black & Decker BD 220/50-2M Instruction Manual

Connect the Blue wire to the terminal marked Neutral (N). Connect the
Brown wire to the terminal marked Live (L). Ensure that the outer insulation
is gripped by the cord grip and that the wires are not trapped when replacing
the plug cover. The mains lead on this product is fitted with a 13 amp
(BS1363/A) plug. A 13 amp (BS1362) fuse must be fitted in the plug.
If in doubt consult a qualified electrician
There are no user serviceable parts inside this product except those referred
to in the manual. Always refer servicing to qualified service personnel. Never
remove any part of the casing unless qualified to do so; this unit contains
dangerous voltages.
Warning!
For your protection if this product is to be used outdoors it should not be
exposed to rain or used in damp locations. Do not place the product on damp
surfaces, use a workbench if available. For added protection use a suitable
residual current device (R.C.D.) at the socket outlet.
Note: If the mains cable requires replacing it must be replaced with an
identical one and fitted by a qualified person.
3-phase version 400 V / 50 Hz
● The compressor is equipped with a mains cable with a 16A CEE plug. This
plug has a phase converter . Before you put the equipment into operation,
check whether the motor rotates in the correct direction (see the direction
arrow on the V-belt cover) by switching on the compressor briefly. If the
compressor motor rotates in the wrong direction, you must correct the ro-
tating field by reversing the phase converter in the plug (use a screwdriver
to depress the phase converter slightly and turn it through 180°).
● The motor is equipped with an overload switch. If the compressor over-
loads, the overload switch will switch off the equipment automatically to
protect the compressor from overheating. If the overload switch triggers,
wait for the compressor to cool down.
● Long supply cables, extensions, cable reels etc. cause a drop in voltage
and can impede motor start-up.
● In the case of low temperatures below +5°C, motor start-up is jeopardized
as a result of stiffness.

START-UP AND USE

• Check that the rating data match the effective characteristics of the system
(voltage and power).
• Check for correspondence between the compressor plate data with the
actual specifications of the electrical system. A variation of ± 10% with
respect of the rated value is allowed.
• Insert the power plug in a suitable socket checking that the button of the
pressure switch located on the compressor is in the "O" (OFF) position
(figures 5a-5b-5c).
• For the 3-phase versions, connect the plug to a panel protected by suitable
fuses.
• For the versions fitted with electric panel ("Tandem" control units or delta/
star starters) have installation and connections (to the motor, to the
pressure switch and to the electrovalve if any) carried out by qualified
personnel.
• Check the oil level by means of:
– The sight glass (fig. 6a),
– Or the oil dipstick (figures 6c - 6d).
And then, if necessary, unscrew the vent plug and top up (with new oil).
• At this point, the compressor is ready for use.
• Operating on the switch of the pressure switch (or the selector for versions
with electric panel), (figures 5a-5b-5c), the compressor starts, pumping air
in the reservoir through the delivery hose.
• On reaching maximum operating pressure (factory-set during testing), the
compressor stops, venting the excess air present in the head and in the
delivery hose through a valve located under the pressure switch (in delta/
star versions, through an electrovalve that is activated when the motor
stops).
• The absence of pressure in the head facilitates subsequent restart.
When air is used, the compressor restarts automatically when the lower
calibration value is reached (approx. 2 bar between upper and lower).
The pressure inside the reservoir can be checked on the gauge provided
(figures 4a-4b-4c).
• The compressor continues to operate automatically with this work cycle
until the position of the switch of the pressure switch (or of the selector of
the electric panel) (figures 5a-5b-5c) is modified. To use the compressor
again, wait at least 10 seconds after this has been switched off before
restarting.
• In the versions with electric panel, the pressure switch must always be
aligned with the I (ON) position.
• In tandem versions, the control unit provided permits use of only one of
the two compressor groups (if necessary alternatively) or of both at the
same time according to requirements. In this second case, start-up will be
differentiated slightly to avoid excessively high current take-off at start-up
(timed starting).

• Only the wheel-mounted compressors are fitted with a pressure reducer
(in the versions with fixed feet, it is usually installed on the use line). Air
pressure can be regulated in order to optimize use of air-powered tools
operating on the knob with the valve open (pulling it up and turning it in a
clockwise direction to increase pressure and counterclockwise to reduce
this) (fig. 7). Once you have set the value required, push the knob down to
lock it.
• The value set can be checked on the gauge (for versions equipped with
this, figures 7 - 8).
• Please check that the air consumption and the maximum working
pressure of the pneumatic tool to be used are compatible with the
pressure set on the pressure regulator and with the amount of air
supplied by the compressor.
• When you have finished working, stop the machine, pull out the plug and
empty the reservoir.

MAINTENANCE

• The service life of the machine depends on maintenance quality.
• PRIOR TO ANY OPERATION SET THE PRESSURE SWITCH TO THE
OFF POSITION, PULL OUT THE PLUG AND COMPLETELY DRAIN THE
RESERVOIR.
• Check that all screws (in particular those of the head of the unit) are tightly
drawn up (figures 9a-9b). The control must be performed before the first
start-up of the compressor and subsequently before the first intensive use
in order to restore the correct closing torque value modified as a result of
heat expansion.

• Clean the suction filter according to the type of environment and in any
case at least every 100 hours. If necessary, replace the filter (a clogged
filter impairs efficiency while an inefficient filter causes harsher wear on the
compressor (figures 10a - 10b).
• Change the oil after the first 100 hours of operation and subsequently
every 300 hours. Check the oil level periodically.
• Use API CC/SC SAE 40. (For cold climates, API CC/SC SAE 20 is
recommended). Never mix different grade oils. If the oil changes color
(whitish = presence of water; dark = overheated), it is good practice to
replace the oil immediately.
• After topping up, tighten the plug (figures 11a - 11b - 11c) making sure that
there are no leaks during use. Once a week, check the oil level to assure
lubrication in time (figures 6a - 6d).
• Periodically (or after completing work if for more than an hour), drain the
condensate that forms inside the reservoir due to the humidity in the air
(fig. 12) in order to protect the reservoir from rust and so as not to restrict
its capacity.
• Periodically, check the tension of the belts which must have a flexion (f) of
around 1 cm (fig. 13).
