GENERAL MACHINE MAINTENANCE
LP GAS SYSTEM
The propane powered SR7770HC is identical to the “standard” gasoline powered SR7770HC, except that its fuel
system has been modified to operate on LP vapor fuel.
The LP fuel system consists of several components not found on the gasoline system. The LP fuel system also
contains the associated mounting hardware and plumbing for the LP components. The major LP components are
as follows: These components are factory set, attempts at adjusting these components should only be made by
authorized service personnel.
1.
An LP carburetor
2.
A combination water heated vaporizer and regulator
3.
A combination LP fuel line filter and lock off valve
4.
An LP fuel tank and fittings
LP GAS VAPORIZER-REGULATOR QUICK CHECK
Turn on the ignition switch and open the radiator cap. Check the coolant for bubbles. If bubbles are present, the
vaporizer may have a leaking gasket or may have developed a pinhole leak, allowing the LP fuel to enter the
cooling system.
LP GAS FUEL TANK
The LP tank is located under the driver’s seat. Use only the proper size and type of LP tank. The SR7770HC LP
powered sweeper uses 33.5 lb. liquid withdraw tank. The DOT designation of the tank is DOT 4BW-240.
NEUTRAL ADJUSTMENT
NOTE
Orientation of the transmission arm assembly depends upon which engine is installed in the
SR7770HC.
NOTE
Adjustment directions given are as seen from the operator’s position in the driver’s seat.
1.
Check engine no load RPM; SR7770HC, 2150 RPM. Check hydraulic reservoir oil level.
2.
Raise rear of machine onto jack stands so rear wheel is off the ground.
3.
Loosen the jam nut away from the adjustment nut.
4.
If the rear drive wheel is turning forward, turn the adjustment nut clockwise (this will shorten the threaded
shaft). If the rear drive wheel is turning in reverse, turn the adjustment nut counter clockwise (this will
lengthen the threaded shaft).
5.
Tighten the jam nut against the adjustment nut.
6.
Test for operation of neutral with engine at full throttle. If the rear drive wheel turns, repeat adjustment
steps 3, 4 and 5.
