Maintenance Chart - DeWalt D55166 Manual De Instrucciones


CAUTION: Risk of unsafe operation. Ensure proper
footing and use caution when rolling compressor so
that unit does not tip or cause loss of balance.
2. When location is reached slowly lower compressor
to ground. Always store compressor in a horizontal
position. nOTE: Should the unit tip over, hard starting
and smoking will occur due to oil spillage.
MAINTENANCE

WARNING: To reduce the risk of serious personal
injury, turn unit off and disconnect it from
power source before making any adjustments or
removing/installing attachments or accessories.
An accidental start-up can cause injury.
The following procedures must be followed when
maintenance or service is performed on the air compressor.
1. Ensure On/Off switch is in the OFF position.
2. Remove air compressor plug from outlet.
3. Drain air tank.
4. 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 D WALT authorized service center.

1 - 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.
2 - Remove tank from service. For more information, call our Customer

** The pump oil must be changed after the first 20 hours of operation.
Thereafter, when using ISO 100/SAE40, non-detergent, premium air
compressor oil, change oil every 200 hours of operation or once a year,
whichever comes first.
+ Perform more frequent in dusty or humid conditions
Checking Safety Valve (Fig. A)

WARNING: Hot surfaces. Risk of burn. Aftercooler,
pump head, and surrounding parts are very hot, do
not touch (see the Hot Surfaces identified in Fig. B).
Allow compressor to cool prior to servicing.

WARNING: Risk of bursting. If the safety valve does
not work properly, over-pressurization may occur,
causing air tank rupture or an explosion.

WARNING: Risk from flying objects. Always wear
certified safety equipment :
ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side
shields when using the compressor.
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.
Checking Air Filter Element (Fig. A, E)

WARNING: Hot surfaces. Risk of burn. Aftercooler,
pump head, and surrounding parts are very hot, do
not touch . Allow compressor to cool prior to servicing.
1. Ensure the On/Off switch
2. Allow unit to cool.
3. Remove air filter 12 from unit.
4. If element needs cleaning, blow out with air. Replace
if needed. Purchase replacement parts from your local
dealer or authorized service center. Always use identical
replacement parts.
5. Reassemble air filter to unit. Ensure inlet points down.
NOTICE: Risk of unsafe operation. Do not operate
without air inlet filter
Draining Air Tank (Fig. A)
nOTE: The amount of water drained from the tank after
each use will depend on the time of use and the amount of
humidity in the operating environment. If no water comes
out of the drain valve, the valve may be clogged. If the valve
is clogged, release all air pressure from tank. The valve can
then be removed, cleaned and reinstalled.

WARNING: Risk of unsafe operation. Risk from noise.
Air tanks contain high pressure air. Keep face and
other body parts away from outlet of drain. Use safety
glasses [ANSI Z87.1 (CAN/CSA Z94.3)] when draining
as debris can be kicked up into face. Use ear protection
[ANSI S12.6 (S3.19)] as air flow noise is loud when
draining.
nOTE: All compressed air systems generate condensate
that accumulates in any drain point (e.g. tanks, filter,
aftercoolers, dryers). This condensate contains lubricating
