FUEL REQUIREMENTS

ASTM No. 2 diesel fuel is recommended for these
engines. The use of No. 2 diesel fuel will result in
optimum engine performance. When normal operating
temperatures are below 32 degrees F. (0 degrees C.), it
is acceptable to use a seasonal blend of No. 2 fuel. The
use of lighter fuel will reduce fuel economy. (SEE THE
ENGINE OPERATOR'S MANUAL FOR ADDITIONAL
FUEL INFORMATION.)

Filling the Fuel Tank

These units are equipped with a single internal fuel
tank. The YLT6010DE has a 20 gallon tank and the
LLT6012DE has a 35 Gallon tank. Use caution when
filling the tank to prevent it from overflowing.

These units will require installation of a coustomer
purchased 12 volt battery for starting. The YLT6010DE
requires a group U1 235CCA battery and the
LLT6012DE requires a group 24F 600 CCA battery.
When connecting the battery, ALWAYS CONNECT
THE POSITIVE CABLE FIRST and THE NEGATIVE
CABLE LAST! Disconnecting the battery is done in
reverse, disconnecting the negative cable first and then
the positive cable.

WARNING ! - POTENTIAL BATTERY

EXPLOSION !

This unit uses a negative ground. Connecting the
negative cable first makes the battery positive terminal

HOT. Connecting the positive cable last may result in
an accidental short circuit of the positive battery
terminal to any of the surrounding metal surfaces (i.e.
dropping a tool, wrench swing etc.). Use extreme
caution whenever making or breaking the battery
connections and follow the correct sequence carefully.

c. “START” - This switch position engages the

engine starter and the pull-in coil on the fuel solenoid.

3. Alarm Light - This light will be lit if the unit has
shutdown on low oil pressure.

INSTALLA TION OF LIGHTS

The four flood lamps for the Mobile Lighting System
have been shipped on a separate pallet to prevent
damage during shipment. Carefully unpack and inspect
the lamps prior to installing them on the tower crossbar.

The individual lamps have been prewired and hardware
provided for their installation. Two lamps are installed on
the top of the crossbar and two are attached to the
bottom of the crossbar. The lights should be tipped
straight down and the swivel joints locked before
towing.

CAUTION: LIGHT BULB DAMAGE

Never handle the metal halide bulbs with your bare
hands! Doing so will leave traces of normal body oil
deposits on the bulbs which will shorten the bulb life. In
addition, a hot bulb will cause severe burns instantly.
See the Maintenance section of this manual for the
proper procedures.
