SECTION 5. OPTIONAL EQUIPMENT
5.1 ROTATOR
A Platform rotator allows for platform rotation 90 degrees
from center in either direction. The rotator is designed to
give added jobsite versatility. The platform should be
returned to the center position for all other operations.
5.2 DUAL FUEL SYSTEM (GAS ENGINE
ONLY)
Description
The dual fuel system enables the standard gasoline
engine to run on either gasoline or LP gas. The system
includes pressurized cylinders mounted on the frame, and
the valves and switches needed to switch the fuel supply
from gasoline to LP gas or from LP gas to gasoline.
A two position, FUEL toggle switch at the ground control
station supplies electrical power to open the LP gas shut-
off solenoid and close the LP gas shut off solenoid when
positioned to the GASOLINE position. This switch sup-
plies electrical power to open the LP gas shut-off solenoid
and close the gasoline shut-off solenoid when positioned
to the LP position.
IT IS POSSIBLE TO SWITCH FROM ONE FUEL SOURCE TO THE
OTHER WITHOUT ALLOWING THE ENGINE TO STOP. EXTREME
CARE MUST BE TAKEN AND THE FOLLOWING INSTRUCTIONS
MUST BE FOLLOWED.
Changing From Gasoline to LP Gas
1. Start engine from Ground Control Station.
2. Open hand valve on LP gas supply tank by turning
counterclockwise.
BE SURE GASOLINE IS EXHAUSTED BEFORE SWITCHING TO LP
GAS. SEE STEP (3) BELOW.
3. While engine is operating, place DUAL FUEL switch
at Ground Control to center OFF position. Allow
engine to operate without load, until engine begins
to stumble from lack of gasoline. As engine begins
to stumble, place the switch to LP position, allowing
LP gas to flow to the fuel regulator.
Changing From LP Gas to Gasoline.
1. With engine operating on LP under a no-load condi-
tion, position DUAL FUEL switch at Ground Control
Station to GASOLINE position.
2. If engine stumbles because of lack of gasoline,
place the switch to LP position until engine regains
smoothness, then return switch to GASOLINE posi-
tion. Repeat as necessary until engine runs
smoothly on gasoline.
3. Close hand valve on LP gas supply tank by turning
clockwise.
5.3 OSCILLATING AXLE
The oscillating front axle is attached to the frame by a
pivot pin which allows all four wheels to remain on the
ground when traveling on rough terrain. The oscillating
axle also incorporates two lockout cylinders connected
between the frame and each wheel end. The lockout cylin-
ders permit axle oscillation when the boom is centered
over the rear, and lock and hold the axle when the boom is
moved off center.
5.4 TOW PACKAGE
The tow package is required when it is necessary to move
the machine without use of the drive and steer system.
TOWING IS PERMITTED ONLY FOR EMERGENCY TRAVEL ON THE
JOBSITE. NO HIGHWAY TOWING IS PERMITTED.
The towing package consists of the tow bar, attaching
hardware, a tow bar which connects to the eyes on front
of frame and the towing vehicle, and a tow/steer selector
valve which permits the steering system to ‘float free’
when towing the machine.
5.5 FOUR WHEEL DRIVE
Provides drive motors, brakes and torque hubs at each
wheel to give extra traction. The system is a full time four
wheel drive system and is available with either a fixed or
oscillating front axle.
