2.17 Refilling propane tanks

The proper filling of propane tanks is a subject so important that it warrants special attention.
Propane tanks should only be filled by qualified propane dealers.
• Most important, propane tanks should be filled no more than 80% of their rated capacity.
The other 20%, which is about 4" (10 cm) from the top of the cylinder, is called the vapor
space or headspace. This vapor can be compressed without causing the pressure relief valve
to open and vent gas to the area around the cylinder. If there is no headspace to allow
for fuel expansion, the pressure relief valve will open, releasing propane gas into the
atmosphere. This is a very dangerous and volatile situation as there is always the possibility
that enough of the vented gas could find its way down to the floor and come in contact with
a pilot light from a furnace, hot water heater, or other source of ignition. Propane changes
into a gas, is -44" F (-42° C). Exposing unprotected skin to propane gas or liquid could result
in frostbite injury.
• All new tanks should be vented and purged of air per manufacturer's instructions before
use. Never bleed propane tanks indoors.

2.18 Storage propane tanks

When not in use, propane tanks always should be stored outside in an upright position in a
secure, tamperproof, steel mesh storage cabinet. This cabinet may be located next to the
building but with at least five feet (1.5 m) of space between the cabinet and the nearest
building opening (door or window), also away from heat and direct sunlight.

2.19 Transporting propane tanks

When transporting cylinders to a propane dealer or to a job, make sure the cylinders are
securely fastened and standing in an upright position with the service valve closed.
• A cylinder rattling around in the back of a vehicle and banging into other objects
constitutes a hazard. Avoid dropping or banging cylinders against sharp objects.
• The propane cylinders are sturdily constructed but a series of hard jolts could cause
damage.
• Please note that any cylinder that has been filled is always considered full, no matter how
little propane gas remains in it. This is because even when all liquid has evaporated into
vapor there is still some propane gas vapor left in the cylinder. Because this remaining fuel
is flammable, an empty cylinder should be treated with the same careful procedures as one
that is filled to the 80% level with liquid propane. The only time that a cylinder is considered
empty is when it is new, before it has been filled with propane.
• When transporting a propane powered floor machine, the propane cylinder may be
strapped onto the machine as long as the machine itself is firmly secured in the vehicle.
• Of course, spare cylinders should always be secured in an upright position

2.20 Definition of the "Safety off position"

The machine is in a safe condition where it cannot be any hazard.
How to set the machine in the Safety off position:
1. Turn off the machine, with minimum throttle and remove the Start key
2. If a dust collector is used, switch it off
3. Wait for all drives to come to a complete stop
4. Press down the emergency button, close the valve on the propane tank
5. Secure against unintended restart
Always remove the start key on the machine to prevent other persons from accidentally
starting it while working on the machine.

2.21 Safety regarding maintenance

Set the machine into the Safety off position before beginning any work on the machine.
See "2.20 Definition of the "Safety off position"".
Never work on the machine while battery or propane tank still is connected!
All parts must have come to a complete stop before beginning any work!
When the machine is lying down on its back it might tilt to it's upwards position. Take extra
care to prevent this from happening to ensure that no injuries or damages occur.
When the machine has been operated the segments, Scan-On plates and other parts on the
gear barrel may be hot. Take extra care to prevent burn injuries.
Adjustment, servicing and inspection work on the period of time limits, specified in this User
Manual as well as any information on the replacement or parts and equipment must be undertaken
and/or complied with!
These activities may only be undertaken by qualified personnel.
When the machine has been operated the Kawasaki motor is extremely hot. Take extra care
to prevent burn injuries.
See "2.20 Definition of the "Safety off position"" for further information.
