Winter Operation; Removal, Disassembly, Assembly And Installation Of The Rotor - AUTO GYRO Cavalon Pro Pilot Operating Handbook

8.14 Winter Operation

The cooling system for the cylinder heads of the engine is filled with a mixture of anti-freeze
and water, which gives freezing down to -20 °C. Using a hydrometer, check protection
temperature of the coolant and add anti-freeze, if necessary.
If temperatures are expected to fall below protection temperature, drain the coolant, and if
required for service, refill with pure antifreeze. As anti-freeze ages, renew the coolant every
two years. Read the engine manual for the manufacturer's recommendations.
Pure antifreeze is not as good an engine coolant as a 50/50 mix with water.
Take care that engine coolant limits are not exceeded. As soon as ambient
temperatures permit, drain and refill with the normal coolant mix.
During winter operations the necessary operating temperature for oil and cooling agent may
not be reached. This can be compensated by taping some portion of the coolers. Monitor all
engine temperatures closely after having the coolers taped and modify, if necessary.
Before each flight inspect all control cables for free and easy movement and sufficient
lubrication.

8.15 Removal, Disassembly, Assembly and Installation of the Rotor

In order to transport or park the gyroplane with minimum space requirements, the rotor
system can be removed and disassembled, if needed. In order to do so, a second person is
needed to assist and help to prevent any damage to the gyroplane or the rotor system.
The rotor system must be removed and disassembled for road transport. When
handled incorrectly the rotor system can be damaged irreparably. If undetected
this may have catastrophic consequences.
When removing or disassembling make sure to mark all parts so that each and
every component of the rotor system is reassembled and installed in exactly
the same way and orientation. Some rotor blades have loose washers in them
which are required as balance weights. Do not remove or restrain if present!
