HORIZONTAL PROPANE TANK
The standard Lavina 20G-X is equipped with vertical propane tank with vapor draw
. If necessary the machine can work
with horizontal tank but obligatory with vapor draw. Here is how to readjust the machine for horizontal propane tank:
Dismount the support that carries the strap holding the tank. Dismount the strap from the support. Dismount the rear
support of the tank. Remove half of the rubber insulator of the support. Place the strap in the middle of the tank
support and place again the half of the rubber insulator. This support together with the strap should be mounted on
the upper level.
Dismount the front tank support and mount it on the upper level.
Dismount the right support that has the tensioning key of the tank strap.
Mount the key on the carriage using the plate underneath and the available screws and nuts. Adjust the locking
depending on the diameter of the propane tank.
While working do not forget that you should use properly fitted tank with vapor draw, to avoid freeze regulator
problems.

STARTING THE MACHINE
First, follow the directions in the chapter on Safety Devices and Safety Instructions. Check oil level. Open the service valve on
the propane tank about one and a half (counterclockwise) turns. Next, make sure the Start/Stop Clutch rocker (2) is in stop
position and check that the throttle (3) in the IDLE position. This creates the necessary vacuum to open the lock‐off valve inside
the regulator. Actuation of the throttle lever will keep the lock‐off valve from opening and the engine from getting fuel so the
engine will not start. Proper maintenance will insure easy starting. Engage starter (1) for a
MAXIMUM
of 5 to 6 seconds or until
the engine fires. Serious starter damage will result if this is exceeded and the warranty may not apply. Operate the engine at
half throttle for approximately two minutes to properly warm engine. Then advance to full throttle for best results. If working
wet, add water to the floor surface. If working dry, instead switch on the vacuum unit. Finally, hold the machine firmly and push
the start of the Start/Stop clutch button (2).
OPERATING THE MACHINE
Guide the machine in straight lines across the floor, slightly overlapping the previously completed surface with each
new line. Work at a constant speed, allowing the tools time to work at a speed appropriate for the tools’ grit size.
Avoid vibrations. Do not stop the machine while tools are still running as they will mark the surface of the floor. When
working wet, select the destination of the water feed with the water tap (fig. 4.2-1) and periodically run the pump to
