except that the tap provided on the filter should
be turned on before using the equipment.
Af ter use be sure to turn olf the tap and screw
down the hand pump otherwise fuel may drain
from the main tank into the engine.

Use fuel oil in the system.
Check unions, pipes, and supply tank fOT leaks.
Inspect every 1,000 hours to make sure that all
connections and terminals are tight on .. Heater-
Starter " switch and Heater plug.
If any difficulty is found in operating the pump
especially on the downward pressure stroke,
inspect the atomiser swirl and jet hole.

equipment are fitted with a decompressor shaft
in the valve cover.
The decompressor lever is positioned on the

the exhaust valves are opened, thereby relieving
the compression to facilitate easy turning.
To start, put the decompressor lever in \he
vertical position, turn the engine over smartly 8nd
drop the decompressor lever.
It should be noted that where a decompressor
shaft is fitted, loss of compression in ODe or more
cylinders may be caused by this shaft fouling one

closure of a valve or valves. The remedy is a
ney.' cylinder head cover joint.
If the engine is particularly cold lift the decompressor
lever and turn the engine over a few
time~ before attempting to start.

position until the engine ceases to. rotate. Ensure
that the control returns to the run position otherwise
difficulty may be experienced in restarting
