STARTING AND STOPPING
To Start Engine by Hand :
Make it a practice to check the lubricating oil level, the fuel level and the cooling water level before starting.
If engine is being started for the first time ensure that all foregoing points of lubrication have been attended to and that the fuel system is primed.
Swing valve lifter(s) under tappets.
Screw in tightly the compression changeover valves on cylinder heads (6/1 and 12/2 only).
Disengage cut-off hand lever by pushing it downwards and trip the overload pawl on the fuel pump.
Place starting handle on the engine crankshaft extension and turn. Disengage exhaust valve lifter(s) as quickly as possible, and lock in off position. Engine should fire as soon as one valve has been released. Retain grip on starting handle and remove from crankshaft.
Check ail indicator plug to see that oil pump is working. If oil pressure indicator gauge is fitted, open tap to check pump is working and quickly close it again (12/2 & 16/2 engines only).
Check that ruling water is circulating.
Load can be applied as soon as engine has attained full speed. Up to 1/3 load, compression change-over valve(s) should remain screwed in, but when more than 1/3 load is applied, screw change-over valve(s) out as far as it (they) will go. (8/1 and 16/2 engines are not fitted with compression change-over valves).
To Stop Engine :
Lift cut-off hand lever.
When engine is about to stop, engage valve lifter. Never stop engine by shutting off fuel supply or by lifting the exhaust valve.
Speed and Load Regulation :
A slight adjustment of speed may be made. To increase speed, turn the knurled adjusting nut in a clockwise direction, increasing the tension of the spring. To reduce the speed, turn the knurled nut in the opposite direction
THE SPEED MARKED ON THE ENGINE MUST NOT BE INCREASED BY MORE THAN 2½%.
