2.6 TORQUE REQUIREMENTS
The Torque Chart in this section consists of standard
torque values based on bolt diameter and grade, also
specifying dry and wet torque values in accordance with
recommended shop practices. This chart is provided as
an aid to the operator in the event he/she notices a condi-
tion that requires prompt attention during the walk-around
inspection or during operation until the proper service per-
sonnel can be notified. This section provides specific
torque values and periodic maintenance procedures with
a listing of individual components. Utilizing this Torque
Chart in conjunction with the preventive maintenance pro-
cedures, will enhance safety, reliability and performance
of the machine.
NOTE: All wheel lugs are to be torqued at 105 ft lbs.
2.7 DUAL FUEL SYSTEM
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 platform 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 two position
LPG/GAS SELECT switch at the platform control sta-
tion to LP.
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 platform 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.
