GENERAL INFORMATION
ENGINE BREAK-IN
Your new Engine does NOT require extensive “break-
in”. However, for the first 100 hours of operation, keep
the following in mind. Allow the Engine to idle for a
few minutes after every cold start. Do NOT idle the
Engine for long periods of time. Do NOT operate the
Engine at maximum power for long periods of time.
Check the oil level frequently and replenish, as neces-
sary.
A special “break-in” oil is NOT used. The oil in the
Engine crankcase is the same specified for regular oil
changes. Change the oil and replace the oil filter at the
intervals specified in the Service chapter. Do NOT add
special additives or special “break-in” components to
the crankcase.
BEFORE STARTING ENGINE
Before starting the Engine and running the Paver, refer
to the Controls & Accessories Chapter and familiarize
yourself with the various operating controls, Indicators
and safety features.
STARTING THE ENGINE
BEFORE mounting the Screed Platform, walk com-
pletely around the machine to make sure NO one is, on,
or close to it. Let others near the area know you are
going to start up and wait until everyone is clear of the
machine.
Place all hydraulic function controls and the hydraulic
Pump speed control Lever in “neutral” position.

OPERATION & ADJUSTMENTS
For 1639 Gas Models
1. Pull the Throttle control 1/4 to 1/2 open.
2. Pull Choke control to full “out” position (close
Choke Valve) for cold Engine starts. If re-starting
a warm Engine, little or no choking is required..
3. Turn the Key to START position. When Engine
starts, release the Keyswitch and it will automati-
cally return to the RUN position.
4. Gradually return the Choke control to full “in”
position (open Choke Valve) as Engine warms up
and begins to operate smoothly.
For 1649 Diesel Models
1. Set the Throttle Control to 1/3 open.
2. Turn the Key to the START position. When the
Engine starts, release the Keyswitch and it will
automatically return to the RUN position.
3. In cold weather starting, first turn the Key coun-
terclockwise to activate Glow Plug. When the
Indicator lamp comes on, proceed as in Step 2.
NOTE:
Crank the Starter until the Engine is start-
ed. If the Engine fails to start within 15 seconds,
return the key to the “OFF” position, wait 2 min-
utes, and try to restart the Engine. Cranking the
Engine for longer than 15 seconds will result in
premature failure of the Starter.
After the above steps proceed as follows:
1. Allow a sufficient Engine warm-up time before
attempting to operate the Controls.
2. Check that Indicators are in normal condition.
3. Check the color of the exhaust gas. It should be
light blue or colorless.
4. Check that there are NO fuel, oil or Engine coolant
leaks, and NO abnormal noises or vibrations.
CAUTION
BEFORE starting the Engine and operating the
Paver, review and comply with ALL safety rec-
ommendations set forth in the SAFETY chap-
ter of this manual. Know how to STOP the
Paver BEFORE starting it.
