SYSTEMS DESCRIPTION
ROTOR BRAKE
The rotor brake is mounted on the aft end of the main
gearbox and is actuated by a cable connected to a pull
handle located on the cabin ceiling. To stop the rotor, use
the following procedure:
1. After pulling mixture off, wait at least 30 seconds.
2. Pull brake handle forward and down using moderate
force (approximately 10 lb).
3. After rotor stops, it is recommended to use the rotor
brake as a parking brake by hooking bead chain in slot
in bracket.
The brake must be released before starting the engine.
When the brake is engaged, the starter is disabled.
CAUTION
Applying rotor brake without waiting at least
30 seconds after engine stops or using a force
which stops rotor in less than 20 seconds
may damage brake shoes.
ENGINE PRIMER SYSTEM (OPTIONAL)
The primer is used to improve engine cold starting. The
primer pump is normally mounted to the steel tube frame
and is accessible through the lower right cowl door.
Some early R44s have the pump mounted in the control
tunnel and a knob just forward of the pilot’s seat which
actuates the pump via a push-pull cable. Engine priming is
performed as follows:
1. Unlock pump handle and pump as required for priming
(normally two to three strokes). Pull handle up slowly
to allow time for fuel to fill pump.
2. After priming, push handle full down and lock.
