1. Refer to Fig. 2 and remove the cap from the capsule
container. Insert a fluid capsule in the container.
CAUTION: Mount the capsule in an upright
position within the container. Use care when
handling, since the starting fluid is both toxic and
inflammable.
2. Pull the piercing shaft all the way out and thread the
cap tight on the container.
3. Push the piercing shaft down until it bottoms. This
will break the capsule and fill the container with starting
fluid vapor.
4. Move the engine throttle to the full-fuel position.
5. Engage the starter and simultaneously pull the pump
plunger all the way out. Then push the plunger in slowly,
forcing the starting fluid through the atomizing nozzle and
into the air intake. Continue to push the pump plunger in
until the engine starts. If the plunger is not all the way in
when the engine starts, push it in very slowly until it locks
in the in position.
6. Unscrew the cap and remove the used capsule. Do
not leave the empty capsule in the container.
7. Reinstall the cap tightly on the container body.

NOTE: When not in use, the piercing shaft
