INTRODUCTION
To insure proper understanding of operation, cleaning and maintenance of your TYMCO RE-
GENERATIVE AIR SWEEPER, it is necessary that this Operator’s Manual and the Service &
Parts Manual be read and studied from cover to cover by the Operator. A full understanding of
this equipment will help the operator achieve the results expected of this machine.
Though, seemingly, a very simple machine, the TYMCO REGENERATIVE AIR SWEEPER
utilizes air instead of conventional rotary brushes, brooms and conveyers. Aerodynamic prob-
lems that arise in the REGENERATIVE AIR SWEEPER are not as easily identified and, there-
fore, necessitates a complete understanding of the machine.
The TYMCO REGENERATIVE AIR SWEEPER is designed to maintain cleaner surfaces at
higher speeds and at lower cost. The performance capability of this truly modern machine is
only limited by the initiative of those responsible for its operation. There are many different con-
ditions found in sweeping, and we believe it impossible to answer all of the problems here.
Most important in the operation and maintenance of this machine, is that it should be KEPT
CLEAN.
The Operator’s Manual includes the necessary checks, operating and adjustment procedures
needed by the operator from day to day. For any specific adjustment, problem, or maintenance
checks not explained in this manual, please refer to the Service & Parts Manual.

THE TYMCO REGENERATIVE AIR SYSTEM
DESCRIPTION
The blower generates a constant blast of high velocity air that is directed down the pressure
side of the machine and into the pick-up head. Blast air travels across the pick-up head, picking
up normal debris and refuse in its path and sending it up the suction side of the machine.
At the same time that the blower is directing pressure down the pressure side, it is taking air
from inside the hopper, creating a suction; and consequently, it pulls debris up into the hopper.
The debris is deposited into the hopper while dusty air passes through the screen to a
multipass, centrifugal dust separator. The fines are then deposited back into the hopper
through the skimmer slot. Air, containing very fine dust, then moves into the blower and repeats
its cycle.
The unique REGENERATIVE AIR SWEEPER uses no restricting filters, resulting in more en-
ergy to do your work. Since the blower is used to push and pull, restriction due to clogging or
modification to any of the air passages will greatly affect the sweeper’s performance. In other
words, PRESSURE FOR THE BLAST depends on ample volume of air through the suction;
SUCTION depends on the discharge of air from the blast orifice.
Another point to consider is the fact that a very small air leak at the dump door, inspection
doors, hand hose door, or suction hose will often cause a dusty condition. If the leak is severe
enough, air will have a slower velocity and performance will be lowered.
DO NOT ALLOW EVEN A SMALL AIR LEAK
CLEAN FRESH AIR DRAWN IN WILL BE DISCHARGED AS DUST
TYMCO REGENERATIVE AIR SWEEPER CAPABILITIES
We at TYMCO honestly believe that government officials, contractors and all personnel directly
responsible for the performance and maintenance of equipment in their charge are concerned
with all phases of their operation.
Sweepers are one of the most controversial pieces of equipment with reference to operating
cost, performance, and maintenance. The general public does not realize the problems and de-
pends on people knowledgeable in this area. You, therefore, the person responsible for the
performance and maintenance of the sweeper should use your knowledge and experience to
achieve the results expected.
The TYMCO REGENERATIVE AIR SWEEPER can achieve your anticipated results while
keeping cost at a minimum. However, to realize the full potential of the TYMCO REGENERA-
TIVE AIR SWEEPER, YOU MUST UNDERSTAND ITS CAPABILITIES AND ADHERE
CLOSELY TO OPERATING AND JOB FUNCTIONS FOR WHICH IT WAS DESIGNED.
It is a fact that a licensed driver can operate this equipment; however, we strongly recommend
that the same driver operate it daily. It is proven that ability on the equipment is increased with
experience. We suggest that every operator thoroughly read and study the manual to make
sure that he/she understands its operation before ever attempting to operate the sweeper. It is
very important that every new operator be given this opportunity and that he does not rely solely
on methods of previous operators.

600OPTRS 2 2008
A TYMCO REGENERATIVE AIR SWEEPER can be expected to clean normal debris that may
accumulate on streets, parking lots, and other flat paved surfaces. Using the machine for more
than it was originally designed will cause excessive wear and failure to achieve the desired
results.
This sweeper is not a Vacuum Cleaner. Cleaning is actually done by a stream of high velocity
air the full width of the pick-up head. A blower furnishes both pressure and suction. Air pressure
from the blower passes over the surface being swept within the pick-up head, blows up debris
in its path, and the suction pulls it into the hopper, where it is separated. Air continues on into the
blower and the cycle is repeated.
The TYMCO REGENERATIVE AIR SWEEPER is not intended nor is it expected to replace a
shovel crew or a front end loader. An inspection at the dump site, however, may reveal that
there are rocks and large objects in the hopper. This is due to air currents in the TYMCO RE-
GENERATIVE AIR SYSTEM having the potential to pick up various large objects and retain
them. The mixture of light debris will sometimes boost the large objects into the air stream and
carry them into the hopper. Objects such as cans, bottles, glass, paper, leaves and light stringy
refuse or normal daily accumulation of debris are easily picked up by the sweeper’s unique
REGENERATIVE AIR SYSTEM.
We can not say what blower RPM or truck speed at which you can achieve your sweeper’s full
capabilities because of the various types of sweeping encountered. However, engine RPM
should not exceed 2000. For parking lot sweeping consisting of paper, broken glass, cans,
leaves, etc., engine RPM can be reduced as desired. The sweeper can be operated at truck
speeds up to 10 MPH without changing blower RPM. The above limits are intended for smooth
wide open spaces that are sparsely scattered with debris. Slower truck speeds are advisable
for curb and gutter work or where there are many obstacles. This prevents damage and wear to
pick-up head and gutter broom. Faster speeds may be necessary under your particular condi-
tions. However, you may expect considerably more wear, not only by the hour as a result of
more coverage, but also by the mile. The heat generated at higher speeds will result in soften-
ing of the materials in contact with the surface. We would advise consideration of these facts
before allowing high speed operation, overloading and machine neglect.
SAVE FUEL, REDUCE NOISE, WEAR AND DUST.
OPERATE AT THE LOWEST POSSIBLE R.P.M. TO ADEQUATELY DO THE JOB.

HOPPER ASSEMBLY
The TYMCO Model 600 hopper has a volumetric area of 7.3 cubic yards and is subjected to the
most severe working conditions of any area on the sweeper. The worst enemy of the hopper
assembly is CORROSION! To prevent the hopper from rusting, it should be thoroughly washed
at the end of each shift. It should be pointed out that even a small rust-through area on the hop-
per will have dramatic effect on the sweeper’s performance. The hopper is the vessel from
which the blower draws air; thus, creating the vacuum necessary to lift debris from the pave-
ment. Even a small seal leak diminishes this vacuum tremendously.
A. DUMP OPERATION & CLEAN OUT
To dump the hopper, use the following procedures:
1. Back into area for dumping. NOTE: Make certain pick-up head is in UP position
before backing sweeper or serious damage could occur.
2. Start sweeper auxiliary engine and let idle.
3. Actuate dump toggle switch located on left side of sweeper just above the left fender
and work hopper door back and forth several times to fully discharge load.
4. Assure that separator door remains closed and latched throughout dumping proce-
dure and prior to returning to sweeping activities. End plates on skimmer hood
should be flush on top of raker plate.
WARNING: Use care when dumping sweeper that no one is between dump
door and hopper when closing dump door!
5. At end of shift, drive sweeper to wash area; open dump door and inspection doors.
Shut off auxiliary engine and open separator door/skimmer hood assembly using
draw cable located at left inspection door. Wash out hopper making certain to
clean the hopper screen, separator, suction hose and bottom of pick-up head.
B. SERVICE
WARNING: Never work in or around hopper with auxiliary engine running.
Always shut engine off before servicing.
Aside from routinely washing out hopper, the hopper assembly requires very little
service.
1. Separator Assembly - the separator is a drum-like area found inside the very front
of the hopper. Its function is to rid the airstream of dust particles through use of
centrifugal force rather than filters. (See Page 7) Service separator daily by using
pull cable handle located behind LH inspection door to open separator door and
wash interior of separator chamber.
NOTE: Separator door is held in open position by pulling cable stop through key-hole
in retainer bracket and sliding up slot and releasing. (See Page 8)

2008 7 600OPTRS
Service separator daily by using pull cable handle located behind left hand inspection door to
open separator door and wash interior of separator chamber.

600OPTRS 8 2008
2. Hopper Seals - The hopper must be maintained air tight for the sweeper to perform
adequately. Daily inspect the inspection door seal, dump door seal, transition seals
and, if hand hose attachment is used, the hand hose door seal. If any section of the
seal material is missing, replace the seal. Refer to Page 9 for seal locations.
3. Hopper Screen - The large screen found inside the hopper is very important for pre-
venting large debris from entering the separator and blower assembly. Inspect the
screen daily. If any large holes are found, do not operate sweeper until screen has
been repaired or replaced. Refer to Page 9 for screen location. Once every 500
hours the hopper screen should be removed and the inlet area above separator
should be cleaned thoroughly. If allowed to become stopped up, the sweeper
efficiency is drastically reduced. Refer to Page 9 for separator inlet location.
4. Skimmer Hood - Inside the Model 600 hopper is a shielded area attached to the se-
parator door. This shielded area is formed by what is called the Skimmer Hood and
is designed to create a void area into which the fine dust removed by the separator
skimmer slot can accumulate. The skimmer hood protects the separator skimmer
slot from being choked off by debris being deposited in the hopper during operation.
IMPORTANT: Always close the separator door before closing the dump door.
Opening the dump door retracts the raker plate so that the sepa-
rator door latches properly when closed.

BLOWER ASSEMBLY
A large turbine type blower is used in the TYMCO Model 600 to generate both the vacuum and
pressure air stream with which to sweep. The blower assembly is found on the left side of the
sweeper in the blower housing (see Page 3) and is driven by an auxiliary engine through a
sheave and belt system.
WARNING:Never reach into the blower housing for any reason if blower
power band is installed!
WARNING:Always remove ignition key from sweeper control panel and/or
disconnect battery ground when working on or near the blower
or blower belt.
A. OPERATION
The blower begins to rotate as soon as the auxiliary engine is started. No clutch is used
to engage or disengage blower.
To increase blower speed, use vernier throttle control on sweeper console. Turn the
knob counter-clockwise to desired RPM. NOTE: If sweeper is equipped with an electric
linear actuator, use the throttle switch.
Reverse procedure to decrease blower RPM. Use vernier override button on top of
throttle knob only for emergency shutdowns.
B. BLOWER RPM SETTING
The Model 600 standard Turbo Charged Auxiliary Engine uses a sheave ratio of 1.45
to 1 - meaning that the blower RPM is 1.45 times faster than the engine RPM. Blower
RPM is; therefore, set by reading the auxiliary engine tachometer. As a rule, the higher
the blower RPM, the heavier the debris which can be picked up providing the sweeper is
in good operating condition. However, higher RPM results in faster component wear so
engine RPM should be set according to the debris load on the street. The following RPM
settings are recommended:
ENGINE RPM
Paper, Leaves, Light Trash 1500
Normal Accumulation of Dirt, Sand and Gravel 1600
Heavy Accumulation of Dirt, Sand and Gravel 1800
DO NOT EXCEED 2400-STD. (2000-TURBO) ENGINE RPM WITHOUT FIRST
CONSULTING THE FACTORY.
