General Requirements - DeWalt D55143 Instruction Manual

Location
All hand carry compressors should be run with the rubber feet rest-
ing on a horizontal, flat surface. Do not stand or step on this air
compressor. Secure compressor if it is located on an incline or at
high levels.
Place the air compressor at least 3 feet (1m) away from obstacles
that may prevent proper ventilation. Keep the compressor away
from areas that have dirt and/or volatile fumes in the atmosphere.
These impurities may clog the intake filter and valves, causing
inefficient operation.
HUMID AREAS
Excessive moisture is likely to occur if the unit is located in an
unheated area that is subject to large temperature changes. A sign
of excessive humidity is a large amount of water in the air tanks.
This extra water will make the compressor cycle on and off more
frequently due to reduced air capacity in the tanks. You may be able
to prevent moisture from forming by increasing ventilation or oper-
ating for longer intervals.
ELECTRICAL
Refer to the safety instructions at the beginning of this manual
before using unit. Observe extension cord safety instructions if nec-
essary. Always shut off the air compressor switch before removing
the plug from the outlet.
NOISE CONSIDERATIONS
Consult local officials for information regarding acceptable noise
levels in your area. To reduce excessive noise, use vibration
mounts or silencers, relocate the unit or construct total enclosures
or baffle walls. Contact a D WALT service center or call 1-800-4-
E

TRANSPORTING
When transporting the compressor in a vehicle, trailer, etc., ensure
that the tanks are drained and the unit is secured. Use care when
driving to avoid tipping the unit over in the vehicle. Damage can
occur to the compressor or surrounding items if the compressor is
tipped.
MOVING
WARNING:
• Perspiration, greasy hands, gloves, etc., may result in loss of
control when carrying compressor.
• Ensure proper footing and use caution when carrying compres-
sor to avoid a loss of balance.
• Do not drag air compressor by its power cord as this may result
in electric shock or damage to the compressor.
• Do not drag air compressor by air hose as this may cause hose
to disconnect creating hose whip or loose component(s) to be
discharged which may result in personal injury.
When moving the compressor, use
the cord wrap to keep the cord in
place. Grasp the handle bars (O) with
each hand or grasp the single bar (P)
to carry the compressor. Carry the
compressor as close to your body as
possible. Due to its weight it may be
desirable to seek assistance in carry-
ing this air compressor.

General Requirements

The piping, fittings, receiver tank, etc., must be certified safe for at
least five times the maximum working pressure of the unit. Use
hard welded or threaded steel or copper pipes, cast iron fittings and
hoses that are five times the maximum working pressure and tem-
perature. Use pipe thread sealant on all threads and tighten joints
thoroughly to prevent air leaks. DO NOT USE PVC PLASTIC.
