Operating Section
Boom Operation, continued:
Visually inspect the area around the hose boom for any objects,
trees, telephone poles, persons or animals which could possibly be
in the path of the moving hose boom.
figure 3.4b
Visually inspect the leaves before vacuuming any for any material
that could be harmful to the leaf vacuum of people. This includes
bottles, wood, steel, glass, stone or other hard or breakable ob-
jects.
NOTE: Do not force the joystick! Pushing
the joystick harder does not make the boom
work harder or faster. Application of too much
force will damage the joystick. Do not make
fast, jerking movements with the boom, try to
move the boom slowly and smoothly. Leaves
will vacuum better and the unit will last longer.

8. Engage the clutch fully using the steps outlined
earlier in this manual.
9. Always keeping the hose nozzle at a 45 de-
gree angle. This allows proper air flow and will
reduce clogging. DO NOT bury the nozzle into
the leaf pile, this will cut off the air flow and will
make vacuuming much more difficult and will
increase the chance of clogging.
10. If leaves are not vacuuming, increase the
engine rpm to 1,800 - 2,000 and try vacuuming
again.
11. NOTE: Wet leaves will need higher rpm's to
vacuum whereas dry leaves will only need
minimal rpm's.
12. Continue moving the nozzle slowly and care-
fully in a sweeping motion above the leaves
while vacuuming.
