SL 40021-EN 1
SL: 40021
Date: 15 July 2011
Product: Compressors
Subject: Air Outlet Flap Cylinder Hose Relocation (Y03)
The air compressor uses a hydraulic cylinder to control
the air outlet flap of the compressor. The oil supply
hose to the cylinder is in close proximity to an exhaust
muffler that can reach high temperatures.
If the oil supply hose to the cylinder experiences a leak,
oil could spray on the exhaust muffler. If the exhaust
muffler temperature is high, the oil spray may ignite
causing a fire in the compressor canopy.
NOTE: If compressor operation is required by the
owner prior to availability of the final
correction, Doosan Benelux SA has
developed a temporary solution as
described in the instruction attached to the
dealer Safety Notice letter.

Procedure
Please read the Operation Manual for safety and
operation related information before working on
this air compressor.
WARNING
AVOID INJURY OR DEATH
Diesel fuel or hydraulic fluid under pressure can
penetrate skin or eyes, causing serious injury or
death. Fluid leaks under pressure may not be
visible. Use a piece of cardboard or wood to find
leaks. Do not use your bare hand. Wear safety
goggles. If fluid enters skin or eyes, get immediate
medical attention from a physician familiar with this
injury. W-2072-0807
NOTE: When relieving system pressure by means of
the service valve(s), a small amount of
pressure will remain in the system. No
maintenance work should be carried out
whilst this situation exists. This pressure
may be relieved slowly by operating the
manual blowdown valve.
