INTRODUCTION:
We appreciate your decision to purchase a Lemmer high
quality professional paint spraying system and believe
you will find it to be the best sprayer you ever owned.
Your Lemmer airless paint machine is capable of spray-
ing a wide variety of latex, oil-based and alkyd paints, as
well as stains, preservatives and other architectural
coatings.  The material you are spraying will have a direct
effect on the amount of pressure required for the optimum
pattern and coverage to be obtained.  We recommend
that before actually beginning your job, you carefully read
this manual and practice with the sprayer until you feel
comfortable using it.
The Lemmer DC-3000 & DC-4000 sprayers are powerful
and versatile enough to be used with a variety of acces-
sories (extra lenghts of hose, extensions, pressure feed
rollers, etc. as shown on page 23) to make them even
more versatile systems.  Ask your supplier about the
recommended accessories for your particular job.

PRODUCT SPECIFICATIONS

PUMP TYPE:
The DC-3000 & DC-4000 units use a double acting piston
pump, with stationary packings and the DC-4000 has a
hard chromed piston. This gives good service life and is a
simple to maintain system. The valves are stainless steel
balls with tungsten carbide seats, giving very good
reliability.
Industrial grade DC motors are used in conjunction with
reliable pressure control sytems.
The DC-4000 uses an innovative electronic control which
varies the speed of the pump in accordance with your
need for pressure and material flow, with a minimum of
fluctuation in spray. This system allows tips as small as
.009" to be used for lacquer, yet perform well with large
tips in heavy bodied products.

ADVANTAGES OF THESE SYSTEMS ARE:
•Pump stops working when you do.  Minimizes wear.
•Motor operates only as fast as the job requires again
 reducing wear (DC-4000 only).
•Accurate spray pattern with minimal overspray.
•Minimal or no thinning of paint products.
•Pumps straight out of original paint container.
•Variable pressure from 0 to 3000 PSI.
•Various nozzles are available for slow to fast spraying.
•Light weight, compact and portable.
•Quiet running and low power consumption.
•Steady spraying pressure - no fan fluctuations.
•Compact paint pump - quick cleaning, less parts to wear.

IMPORTANT NOTICES:
Due to the nature of operation of this unit, even though the motor cuts off, or appears to have cut off, it may re-
start at any time.  Even once the switch has been turned off, there will likely be pressure remaining in the
system. Do not service the unit unless it has been turned off, unplugged and the pressure has been relieved.
Pressure is relieved by turning the prime knob counter clockwise and double checking by triggering the gun.

DO NOT USE STEEL BRAID paint spray hose! The DC-3000 & DC-4000 can only be used with fibre braid hose.
