DeWalt D55270T Manual De Instrucciones página 11

Rotate the manual lock unloaderlever to the
open position to prevent air tank pressure
buildup. Rotate manual lock unloader lever to
the closed position after starting the engine
to allow air tank pressure to build. noTe: Air
will not build in tank when manual lock
unloader lever in the open position.
sAfeTy VAlVe
This valve (I) is designed to prevent system failures
by relieving pressure from the system when the
compressed air reaches a predetermined level. The
valve is preset by the manufacturer and must not be
removed or modified in any way.
AIr InTAKe fIlTer
The filter (A) is designed to clean air entering the pump.
To ensure the pump continually receives a clean, cool,
and dry air supply the filter must always be clean and
the filter intake must be free from obstructions.
AIr TAnK DrAIn VAlVe
The drain valve (J) is used to remove
moisture from the air tank after the air
compressor is shut off.
AIr TAnK Pressure GAuGe
The air tank pressure gauge (D) indicates air
pressure in the air tank.
reGulATeD Pressure GAuGe
The regulated pressure gauge (E) indicates
the air pressure available at the outlet side of
the regulator. This pressure is controlled by the
regulator and is always less or equal to the air
tank pressure.

The regulator knob (F) controls the air pressure coming from the air
tank.
To Adjust regulator:
CLOSED
OPEN
1. Pull regulator knob (F) out.
. Turn knob clockwise to increase regulated pressure and
counterclockwise to decrease regulated pressure.
3. When desired pressure is shown on the regulated pressure
gauge push knob in to lock.
ThroTTle ConTrol
I
When maximum air tank pressure is reached and the unloader
valve vents air, it activates the throttle control on the engine. This
gas saving feature holds the engine at a factory-set idling speed
until air pressure in the air tank drops to reset pressure. The
A
unloader valve then reactivates the throttle control and accelerates
the engine to full throttle.
loW oIl shuT DoWn sensors
The air compressor engine is equipped with a low oil shutdown
sensor. This is a safety device designed to protect your engine
from damage in the event the oil level in the crankcase is below
minimum.
If the oil in the engine gets low while the air compressor is running
it will automatically shut down the engine and will not restart until oil
J
is added to the engine or pump. If the oil is low before start-up, the
engine will not start until oil is added.
noTe: The low oil shutdown sensor is very sensitive. You must fill
D
the engine and pump to the full mark on the dipstick to inactivate
E
this safety device.
