The Hydraulic Power Supply Engine is
used to power the hydraulic functions, should
the tractor not be equipped with hydraulic
hookups.
IMPORTANT
1. CHECK THE FOLLOWING FLUID LEVELS BE-
FORE STARTING THE ENGINE PACKAGE: EN-
GINE OIL, FUEL SUPPLY, HYDRAULIC OIL.
(CHECK OIL LEVEL WHILE SEMITRAILER IS
NOT TILTED AS TILTING WILL CHANGE THE
OIL LEVEL IN THE TANK.)
2. IF THE ENGINE DOES NOT CRANK, CHECK
THE FOLLOWING ON THE BATTERY: CHARGE,
FLUID, TERMINALS, AND CABLES. TAKE COR-
RECTIVE ACTIONS AS NEEDED.
CAUTION
IF THE HYDRAULIC FLUID LEVEL IS
LOW DURING OPERATION, THE SEMI-

RECTLY, RESULTING IN DAMAGE TO
THE SEMITRAILER.

The Engine Ignition Switch, Choke and
Throttle are on the Engine Control Panel
mounted on the driver's side of the trailer.
(See Figure 3-5).
3-14.3
The HYDRAULIC POWER SUPPLY
ENGINE THROTTLE controls the speed at
which the engine operates (See Figure 3-5).
It is a variable position control:
HIGH
In this position, the engine throttle is
fully open, letting it run at full speed.
LOW
In this position, the engine throttle is
closed, letting the engine run at a
slow idle.
3-14.4
To start pull the choke completely out
and set the throttle to the LOW position.
3-14.5
Turn the ignition key to the START po-
sition. The engine should crank and then
start.
CAUTION
DO NOT CRANK ENGINE FOR MORE
THAN 30 SECONDS. IF ENGINE DOES
NOT START CONSULT THE OWNER'S
MANUAL SUPPLIED WITH THE EN-
GINE.
3-14.6
When the engine starts, release the key.
Gradually push the choke lever in until the
engine runs smoothly.
3-14.7
Black smoke from the exhaust and a
rough running engine usually indicate over-
choking.
3-14.8
To adjust the speed, turn the throttle
control in or out, as needed, until the engine
runs smoothly at a speed capable of with-
standing use of the hydraulic controls. The
hydraulic controls should now be functional.
3-14.9
Before shutting it off, allow the engine
to cool down by running at a slow idle for
one to two minutes. Then turn the ignition
switch to the off position.
3-14.10
Once the engine is cool, turn or push
the throttle and choke control completely in
and turn the key to the OFF position.
