PSI/Doosan — Hardware Included:

For these PSI/Doosan models: C185, C185WKUB-T2 Export (E04).

Procedure

1. Remove hardware box from compressor
toolbox.
2. Open box and remove the bag containing
hardware, safety chains and assembly
instructions.
3.Using the jack, raise the front of the unit so
that the legs are approximately 1” above the
ground.
4.Remove the temporary retaining bolts from
both sides of the frame at the drawbar
connection (See Figure 1).
5.Carefully lower drawbar to the Level
Position.
6.Install the four bolts (with pre-applied
thread lock) to the four points inside the
enclosure and torque to 68 ft. lbs.(9.4kg-m)
(See Figure 2).
7.Install safety chains by sliding the second
link of one chain into the slot in drawbar
plate. Fasten chain to plate using taptite and
washer. Repeat for the other chain.
8. Temporarily support drawbar and move
jack from front of compressor to side of
drawbar.

Safety Precautions
General
Ensure that the operator reads and understands the decals and consults the manuals before
maintenance or operation.
Ensure that the Operation and Maintenance manual, and manual holder if equipped, are not
removed permanently from the machine.
Ensure that maintenance personnel are adequately trained, competent and have read the
manuals.
Make sure that all protective covers are in place and that the canopy/doors are closed during
operation.
The specification of this machine is such that the machine is not suitable for use in flammable
gas risk areas. If such an application is required then all local regulations, codes of practice
and site rules must be observed. To ensure that machine can operate in a safe and reliable
manner, additional equipment such as gas detection, exhaust spark arrestors, and intake
(shut-off) valves may be required, dependent on local regulations or the degree of risk
involved.
Air discharged from this machine may contain carbon monoxide or other contaminants which
will cause serious injury or death. Do not breathe this air.
Compressed air can be dangerous if incorrectly handled. Before doing any work on the unit,
ensure that all pressure is vented from the system and that the machine cannot be started
accidentally.
Ensure that the machine is operating at the rated pressure and that the rated pressure is
known to all relevant personnel.
All air pressure equipment installed in or connected to the machine must have safe working
pressure ratings of at least the machine safety valve rating.
If more than one compressor is connected to one common downstream plant, effective check
valves and isolation valves must be fitted and controlled by work procedures, so that one
machine cannot accidentally be pressurized or over pressurized by another.
Compressed air must not be used for a feed to any form of breathing apparatus or mask.
The discharged air contains a very small percentage of compressor lubricating oil and care
should be taken to ensure that downstream equipment is compatible.
If the discharged air is to be ultimately released into a confined space, adequate ventilation
must be provided.
When using compressed air, always use appropriate personal protective equipment.
All pressure containing parts, especially flexible hoses and their couplings, must be regularly
inspected, be free from defects and be replaced according to the Manual instructions.
Avoid bodily contact with compressed air.
The safety valve located on the separator element head must be checked periodically for
correct operation.

Never operate unit without first observing all safety warnings and carefully reading the
operation and maintenance manual shipped from the factory with this machine.
Never operate the engine of this machine inside a building without adequate ventilation. Avoid
breathing exhaust fumes when working on or near the machine. Do not alter or modify this
machine.
A battery contains sulfuric acid and can give off gases which are corrosive and potentially
explosive. Avoid contact with skin, eyes and clothing. In case of contact, flush area
immediately with water.
Exercise extreme caution when using booster battery. To jump battery, connect ends of one
booster cable to the positive (+) terminal of each battery. Connect one end of other cable to
the negative (-) terminal of the booster battery and other end to a ground connection away
from dead battery (to avoid a spark occurring near any explosive gases that may be present).
After starting unit, always disconnect cables in reverse order.
High Pressure Air can cause serious injury or death. Relieve pressure before removing filler
plugs/caps, fittings or covers.
Air pressure can remain trapped in air supply line which can result in serious injury or death.
Always carefully vent air supply line at tool or vent valve before performing any service.
This machine produces loud noise with doors open or service valve vented. Extended
exposure to loud noise can cause hearing loss. Always wear hearing protection when doors
are open or service valve is vented.
Never inspect or service unit without first disconnecting battery cable(s) to prevent accidental
starting.
Do not remove the pressure cap from a HOT radiator. Allow radiator to cool down before
removing pressure cap.
Do not use petroleum products (solvents or fuels) under high pressure as this can penetrate
the skin and result in serious illness.
Wear eye protection while cleaning unit with compressed air to prevent debris from injuring
eye(s).
Disconnected air hoses whip and can cause serious injury or death. Always attach a safety
flow restrictor to each hose at the source of supply or branch line
