Preparation For Use; Initial Setup - DeWalt DPC10QTC-QS Original Instructions Manual

ENGLI S H
Do not modify the plug provided. If it does not fit the available
outlet, a correct outlet should be installed by a qualified
electrician.
Repairs to the cord set or plug MUST be made by a qualified
electrician.

PREPARATION FOR USE

PRE-START CHECKLIST
1. Ensure the On/Off switch (6) is in the OFF position.
2. Plug the power cord into the correct branch circuit
receptacle. See Electrical Connection (above).
3. Ensure air tank is drained, see Draining Air Tank under
Maintenance.
4. Ensure the drain valve (2) is closed.
5. Ensure safety valve (9) is functioning properly, see
Checking Safety Valve under Maintenance.
6. Turn regulator knob (4) anticlockwise until fully closed.
Ensure regulated pressure gauge reads 0 bar (0 psi).
7. Attach hose and accessories.
m WARNING: Risk of unsafe operation. Firmly grasp hose
in hand when installing or disconnecting to prevent hose
whip.
8. Ensure all covers and labels are in place, legible (for labels)
and securely mounted. Do not use compressor until all
items have been verified.
m WARNING: Risk of bursting. Too much air pressure
causes a hazardous risk of bursting. Check the
manufacturer's maximum pressure rating for air tools and
accessories. The regulator outlet pressure must never
exceed the maximum pressure rating.
INITIAL SET-UP
m WARNING: Do not operate this unit until you read and
understand this instruction manual for safety, operation
and maintenance instructions.
BREAK-IN PROCEDURE
m WARNING: Risk of property damage. Serious damage
may result if the following break-in instructions are not
closely followed.
This procedure is required before the air compressor is put
into service for the first time and when the check valve or a
compressor pump/motor has been replaced.
1. Ensure the On/Off switch (6) is in the OFF position.
m CAUTION: If hose is not connected to Quick Connect
body, pull coupler back until it clicks to prevent air from
escaping through the quick connect.
2. Plug the power cord into the correct branch circuit
receptacle. See Voltage and Circuit Protection under
Installation.
8
3. Open the drain valve (anticlockwise) fully to permit air to
escape and prevent air pressure build up in the air tank
during the break-in period.
4. Move the On/Off switch to the ON position. The compressor
will start.
5. Run the compressor for 20 minutes.
6. After 20 minutes, close the drain valve by turning
clockwise. The tank will fill to cut-out pressure and the
motor will stop.
7. Compressed air will be available until it is used or bled off.
STARTING
Check that the mains power matches that indicated on the
electrical data-plate - the permissible tolerance range is
+/-5%. Turn or press into position "0". Fit the plug in the
power socket and start the compressor, moving the On/Off
switch into position "I".
The compressor is fully automatic, and is controlled by the
pressure switch which stops it when tank pressure reaches
maximum value and restarts it when it falls to minimum
value. The pressure difference between maximum and
minimum values is usually about 2.4 bar (35 psi). E.g.:
the compressor stops when it reaches approximately 13.8
bar (200 psi) - maximum operating pressure) and restarts
automatically when the pressure inside the tank drops to 11.4
bar (165 psi).
After connecting the compressor to the power line, run it to
maximum pressure and check exactly how the machine is
operating.
m WARNING: The head/cylinder/delivery tube unit can reach
high temperatures. Take care when working near these parts,
and do not touch them to avoid possible burns.
IMPORTANT
The electro-compressors must be connected to a power
socket protected by a suitable differential switch (thermal
breaker). The motor is equipped with a thermal overload
protector located inside the winding - this stops the
compressor when motor temperature reaches excessively
high values. If the thermal overload protector is tripped, place
the switch in the "Off" (0) position. Unplug the compressor
until it has completely cooled. When cool, reattach the plug
to the power supply and move the switch to the "On" (I)
position. The compressor should start normally. If not contact
your nearest service centre immediately.
ADJUSTING OPERATING PRESSURE
You do not have to use the maximum operating pressure
at all times. On the contrary, the pneumatic tool being used
often requires less pressure. On compressors supplied with
a pressure reducer, operating pressure must be correctly
adjusted.
