Maintenance - DeWalt DPC10QTC-QS Original Instructions Manual

Adjust pressure to the required value by turning the knob (4)
clockwise to increase pressure and anti-clockwise to reduce
it. When you have obtained optimum pressure, lock the knob
by pressing it downward. For pressure reducers equipped
without a pressure gauge, the set pressure can be seen on
the graduated scale located on the reducer body.
On pressure reducers equipped with a pressure gauge,
pressure can be seen on the gauge itself.
NOTE: Some pressure regulators do not have "push to lock",
therefore simply turn the knob to adjust the pressure.
STOPPING THE COMPRESSOR
1. Press the switch into position "0" (according to the type
of pressure switch fitted on the compressor). DO NOT turn
off the unit by switching off at the socket or pulling out
the plug.
2. Turn regulator knob (4) anticlockwise until fully closed.
Ensure regulated pressure gauge reads 0 bar (0 psi).
3. Remove hose and accessory.
4. Drain the air tank, see Draining Air Tank under
Maintenance. Ensure air tank pressure gauge reads 0 bar
(0 psi).
MOTOR OVERLOAD PROTECTOR
The motor has a thermal overload protector. If the motor
overheats for any reason, the overload protector will shut off
the motor. The motor must be allowed to cool down before
restarting. To restart:
1. Set the On/Off switch (A) to OFF and unplug unit.
2. Allow the motor to cool.
3. Plug the power cord into the correct branch circuit
receptacle.
4. Set the On/Off switch to ON position.

Maintenance

m WARNING: To reduce the risk of injury, turn unit off and
disconnect machine from power source and remove the
compressed air from the air tank (Ensure air tank pressure
gauge reads 0 bar (0 psi)) before installing and removing
accessories, before adjusting or changing setups or when
making repairs.
MAINTENANCE CHART
Procedure
Check safety valve
Drain air tank
Check for unusual noise/vibration
Check for air leaks*
Clean compressor exterior
* To check for air leaks apply a solution of soapy water around joints. While compressor is pumping to pressure and after
pressure cuts out, look for air bubbles to form.
An accidental start-up can cause injury.
The following procedures must be followed when
maintenance or service is performed on the air compressor.
NOTE: Allow air compressor to cool down before starting
service.
NOTE: All compressed air systems contain maintenance parts
(e.g., oil, filters, separators) that are periodically replaced.
These used parts may contain substances that are regulated
and must be disposed of in accordance with local, state, and
federal laws and regulations.
NOTE: Take note of the positions and locations of parts during
disassembly to make reassembly easier.
NOTE: Any service operations not included in this section
should be performed by a D
D WALT authorized service centre.
e
DRAINING AIR TANK
The condensation in the tank must be drained
daily by opening the drain valve (2) under the
tank. Take care if there is compressed air
inside the cylinder, as water could flow out with
considerable force.
1. Verify that the compressor is turned "Off".
2. Holding the handle, tilt the compressor toward the drain
valve so it is positioned at the bottom of the tank.
3. Turn the drain valve to open.
4. Keep the compressor tilted until all moisture has been
removed.
CHECKING SAFETY VALVE (9)
m WARNING: Hot surfaces. Risk of burn. Outlet tube, pump
head, and surrounding parts are very hot, do not touch. Allow
compressor to cool prior to servicing.
m WARNING: Risk of bursting. If the safety valve does not
work properly, over-pressurization may occur, causing air
tank rupture or an explosion.
Before starting compressor, pull the ring on the safety valve
to make sure that the safety valve operates freely. If the valve
is stuck or does not operate smoothly, it must be replaced
with the same type of valve.
