2. Moving the Unit Without Engine Power
If it becomes necessary to push and move the vehicle without using the engine, make
certain that the parking brake (6, Fig. 3) is RE LEASED and the transmission gearshift
lever (5) is in NEUTRAL position. Push the brake lever (6) forward to release.
3. Operating the Unit
A. Prestart Inspection
(1) Be sure fuel shutoff valve is OPEN. The valve is located at the fuel tank
outlet (see l-l, Fig. 3, item 14). Turn switch (Fig. 1, item 2) ON and
observe fuel gage (l), then turn switch OFF. Make certain of sufficient
fuel to complete the job to be done. The engine will require approximately
6.6 gallons of fuel per hour, under full load.
(2) Be sure the gearshift lever (Fig. 3, item 5) is in NEUTRAL position.
(3) Be sure parking brake is applied. Pull the lever (6) upward and backward
to apply the brake. The brake lever operates an an over-center locking
principle. Brake application pressure applied to the brake band is adjustable
by a threaded knob located on top of the brake lever handle. Turning the
knob CLOCKWISE increases brake pressure and causes an increase in the
effort required to apply the brake and pull the handle into automatically
locked position. The brake lever handle points almost straight upward when
in locked position.
The brake is released by pushing the lever FORWARD.
(4) Make certain all output-cable plug connectors are properly stored in plug
boxes.
