Chart in conjunction with the preventive maintenance pro-
cedures, will enhance safety, reliability and performance
of the machine.
2.7 DUAL FUEL SYSTEM (IF EQUIPPED)
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 the engine from the ground control station.
2. Open the hand valve on the LP Gas supply tank by
turning counterclockwise.
BE SURE ALL GASOLINE IS EXHAUSTED BEFORE SWITCHING
TO LP GAS.
3. While the engine is operating, place the three posi-
tion LPG/GAS SELECT switch at the ground control
station to the center OFF position. Allow the engine
to operate, without load, until the engine begins to
‘stumble’ from lack of gasoline.
4. As the engine begins to ‘stumble’, place the switch
to the LPG position, allowing the LP gas to be sent
to the fuel regulator.
Changing from LP Gas to Gasoline.
1. With the engine operating on LP gas under a no
load condition, position the LPG/GAS SELECT
switch at the ground control station to the GAS
SELECT position.
2. If the engine ‘stumbles’ because of a lack of gaso-
line, place the switch to the LPG position until the
engine regains smoothness, then return the switch
to the GAS SELECT position. Repeat as necessary
until the engine runs smoothly on gasoline.
3. Close the hand valve on the LP gas supply tank by
turning clockwise.
2.8 TORQUE REQUIREMENTS
The Torque Chart consists of standard torque values
based on bolt diameter and grade, also specifying dry,
wet and loctite torque values in accordance with recom-
mended shop practices. This chart is provided as an aid
to the operator in the event he/she notices a condition that
requires prompt attention during the walk-around inspec-
tion or during operation until the proper service personnel
can be notified. The Service and Maintenance section pro-
vides specific torque values and periodic maintenance
procedures with a listing of individual components. Utiliz-
ing this torque chart in conjunction with preventive mainte-
nan ce section will enha nce sa fety, r elia bili ty and
performance of the machine.
