OPERATION
GENERAL INFORMATION
CAUTION
BEFORE starting the engine and operating the
paver, review and comply with all safety
recommendations in the SAFETY chapter of
this manual. Know how to stop the paver
before starting it.
ENGINE BREAK-IN
IMPORTANT:
Do not suddenly change
engine speed or carry heavy loads during the
first 50 hours of operation because this may
damage the engine and shorten engine life.
The paver does not use a special engine "break-in"
oil. Do not add special additives or "break-in"
components to the crankcase. The oil in the engine
crankcase is the same as used for regular oil
changes. Check the oil level frequently and refill as
necessary. See “Check Engine Oil Level” on
page 55. Change the oil and the oil filter at the
intervals in “Service Every 250 Hours” on page 58.
BEFORE STARTING ENGINE
Before starting the engine and running the paver,
see “Indicators and Controls” on page 23.
STARTING THE ENGINE
Before mounting the screed platform, walk
completely around the paver to make sure no one
is on or close to it. Let others near the paver know
you are going to start the engine and do not start
the engine until everyone has moved away from
the paver.
Place all hydraulic function controls and the
hydraulic pump speed control lever in "neutral"
position.
Complete the following steps to start the engine:
1. Turn the keyswitch to the STOP position.
2. Set the throttle control to 1/3 open.
NOTE:
If starting a cold engine and the
outside temperature is below 40° F (4° C), turn
the keyswitch to the RUN position and leave it
there for 15 seconds before starting the
engine. Turn key to START position to start
engine. See item D in “Instrument Module” on
page 25.
3. Turn the keyswitch to the START position.
If the engine does not start, turn the keyswitch
to the STOP position. Wait 30 seconds to
allow battery voltage to recover and follow the
cold start procedure noted above.
IMPORTANT:
Do not crank the starter for
longer than 15 seconds because the starter
motor overheats. Do not crank the starter if the
engine is either not completely stopped or in
operation because the starter motor pinion or
ring gear will be damaged.
4. After the engine starts, release the keyswitch.
The keyswitch moves to the RUN position.
5. Run the engine at a low, consistent speed for
five minutes before operating any controls.
Listen for any abnormal sounds during this
time.
IMPORTANT:
Do not run the engine with a
load while the engine is cold because black
smoke is emitted and the life of the engine
may be shortened.
6. Check that indicators are in normal condition.
7. Check the color of the exhaust gas. It should be
light blue or colorless.
8. Check that there are no fuel, oil or engine
coolant leaks.
9. Check that there are no abnormal noises or
vibrations.
