When the ambient temperature is low, it may be necessary to use an air heater or a starting fluid to assist ignition of the
NOTE: Starting aids are NOT intended to correct for a low battery, heavy oil or other conditions which
cause hard starting. They are to be used only when other conditions are normal, but the air temperature is
too cold for the heat of compression to ignite the fuel-air mixture.
FLUID STARTING AID
The fluid starting aid (Fig. 8) is designed to inject a highly volatile fluid into the air intake system at low ambient
temperatures to assist in igniting the fuel oil injected. The fluid is contained in suitable capsules to facilitate handling.
The starting aid consists of a cylindrical capsule container with a screw cap, inside of which a sliding piercing shaft
operates. A tube leads from the capsule container to a hand operated pump and another tube leads to the atomizing
nozzle threaded into a tapped hole in the air inlet housing.
Fig. 8 - Typical Fluid Starting Aid
The capsule container should be mounted in a vertical position and away from any heat. Start the engine, using the fluid
starting aid, as follows:
Remove the threaded cap and insert a fluid capsule in an upright position within the container.
WARNING: The starting fluid is toxic and inflammable. Use caution when handling.
Pull the piercing shaft all the way out and install and tighten the cap on the container.
Push the piercing shaft all the way down. This will rupture the capsule and fill the container with the starting fluid.
Move the engine throttle to the maximum speed position.
Engage the starter and at the same time pull the pump plunger all the way out. Push the plunger in slowly, forcing
the starting fluid through the atomizing nozzle into the air intake. Continue to push the pump in until the engine starts. If
the plunger is not all the way in when the engine starts, push it in slowly until it locks in the IN position.
Unscrew the cap and remove the capsule. Do not leave the empty capsule in the container.
Replace the cap on the capsule container and make sure the piercing shaft is all the way down.
The cold weather fluid starting aid will require very little service. Replace the piston seal packing if the pump leaks. If
there is an excessive resistance to pumping, the nozzle may be plugged. Remove the nozzle and clean it.
PRESSURIZED CYLINDER STARTING AID
Start the engine during cold weather, using the "Quick Start" starting aid system (Fig. 9) as follows:
Press the engine starter button.
Pull out the "Quick Start" knob for one or two seconds, then release it.
Repeat the procedure if the engine does not start on the first attempt.
