Petter PH2 engines (UP TO 1988)
To start Petter PH2 engines:
Ensure the parking brake is in the raised
“ON” position.
Ensure gear lever is in the neutral
position.
WARNING If a starting handle is to be
used, see that the shaft is
greased. Make sure the
starting handle can be freely
withdrawn.
On the engine, lift the overload stop (A)
and move the fuel pump rack (D) in the
direction of the arrow to the fully open
position.
Operate the fuel pump priming lever (C)
approximately six times. (This is
unnecessary with a warm engine.)
Lift the decompression lever (B) to the
vertical position. Crank the engine as fast
as possible or use the starter motor.
When the engine is turning at a good
speed, knock down the lever (B). The
engine should now fire.
If the engine does not fire, lift the
decompressor lever (B) and slowly turn
the engine a few times before attempting
to start again. Do not operate the starter
motor for more than 20 seconds at a time.
.
Note: If it is necessary to bleed and prime
the fuel system, consult the PH2
Engine Operators Handbook.
To stop PH2 engines:
WARNING NEVER stop the engine by
using the decompressor lever.
This will lead to damaged
valve seats and cylinder head
joints.
DO NOT stop the engine by
allowing the tank to run dry.
This will make it necessary to
bleed and prime the system.
DO NOT remove or alter the
setting of the overload stop.
It is advisable to run on light load for a
few minutes before stopping.
Raise the priming lever (C) to the vertical
position, or move and hold the fuel pump
rack (D) away from the fly wheel until the
engine stops.
