6. OPERATING INSTRUCTIONS

The leaf vacuum unit type 521 is standard delivered with a 3.3 meter heavy duty suction
hose and suction pipe with adjustable handle. (see fig. 2 detail A & C).
This handle is adjustable for correct body length and turnable for left- and righthanded
people. During the operation the hose is suspended by a swing arm (see fig. 2 detail D),
so that you can work standing up straight with a correctly adjusted handle.
The discharge chute (see fig. 2 detail B) should allways be installed in such manner that
all material is blown out safely into a closed container.
During operation you will move the vacuum pipe over the soil, in such manner that a
regular supply of leaves and air can take place. Do not pull the hose to a tight bend in
front of the impeller housing entry. In case however that any material is blocked in the
suction hose, you can open the entry to the impeller housing, but allways after stopping
the machine first.
For your safety, the engine will run only if the lock bolt is fully tightened and contacts the
safety switch (see fig. 1 pos. 40 & 41). Never operate the machine without the suction
hose installed, the impeller housing entry closed and the safety switch operating
properly.
The leaf vacuum unit type 521 is typically delivered with a 13 HP engine, suitable for most
purposes.

6.1 Machine assembly

For transport reasons the suction pipe, suction hose, swing arm and discharge chute, are
unassembled. For your convenience, please refer to fig. 2 detail A, B, C & D to install these
items.
Before working with the machine a test needs to be carried out first, in order to verify that all
parts are fuctioning correctly. Take care that, during this test, no materials can be aspirated.

6.2 Starting the machine

After studying and following the instructions in the separate Honda engine booklet and the
instructions mentioned above, you can start the engine.
Make sure that at start-up the suction pipe is free and no material can be aspirated.
Then after you have verified that material can be blown out safely into the destined
collection compartment, you start to pick up material slowly and increase the working speed
according to your experience building up.
