Preparation For Use - DeWalt D55271 Instruction Manual

HUMID AREAS
In frequently humid areas, moisture may form in the pump and
produce sludge in the oil, causing running parts to wear out
prematurely. Excessive moisture is especially likely to occur if the unit
is located in an unheated area that is subject to large temperature
changes. Two signs of excessive humidity are external condensation
on the pump when it cools down and a "milky" appearance in
compressor oil. You may be able to prevent moisture from forming in
the pump by increasing ventilation or operating for longer intervals.
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-D
E
assistance.
TRANSPORTING
WARNING: Risk injury from lifting. Unit weighs more than 160 lbs.
(72.6 kg) Do not move or lift without assistance.
CAUTION: Risk of property damage. The wheels and handle do
not provide adequate clearance, stability or support for pulling the
unit up and down stairs or steps. The unit must be lifted, or pushed
up a ramp.
When transporting the com-
pressor in a vehicle, trailer, M, N
etc. ensure that the air tank is
drained and the unit is secured
and placed on a flat horizontal
surface. NOTE: Use
recommended tie down points
(M) when transporting. Use
care when driving so to avoid tipping the unit over in the vehicle.
Damage can occur to the unit
or surrounding items if unit is
tipped. Use a ramp if loading
or unloading the unit from a
height of more than 12"
(304.8 mm).
LIFTING
Always use two people when
lifting and lift from the recommended lift points (N).
WARNING: Risk injury from lifting. Unit weighs more than 160 lbs.
(72.6 kg) Do not move or lift without assistance.
MOVING
1. Grasp handle (O) of compressor, and lift compressor high
WALT for
E
enough so unit can be rolled on the front tire(s).

use caution when rolling compressor so that unit does not tip or
cause loss of balance.
2. When location is reached slowly lower rear of 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.
