PICK-UP HEAD
The pick-up head is the most important component of the TYMCO MODEL 600 REGENERA-
TIVE AIR SWEEPER . But, because the pick-up head must be dragged on the pavement, it can
be seriously damaged by careless operation. Even when the pick-up head is fully raised, it is
still close to the pavement and care must be taken not to damage it in transit.
DO NOT:
1. Back up with pick-up head lowered.
2. Raise pick-up head before lowering engine RPM.
3. Increase engine RPM above idle before lowering pick-up head.
4. Forget to raise pick-up for transit.
5. Cut corners while in transit.
6. Drive over speed bumps or divider turtles higher than two inches.
To lift debris from the ground, a 14" diameter suction nozzle is located on the right side of the
pick-up head. The sweeper blower draws air from the hopper creating a vacuum. A flexible
hose is then used to connect the hopper vacuum to the pick-up head suction nozzle whereby
debris is lifted from the ground and deposited into the hopper. However, because the pick-up
head is 87 inches wide some means must be used to move debris across to the suction nozzle.
Just as debris is lifted into the hopper by the vacuum generated by the blower, the exhaust air of
the blower is used to blow debris over to the suction nozzle. This is done by forcing the blower
exhaust air through an elongated pressure nozzle. TYMCO calls this the Blast Orifice. The
blast orifice opening is 87 inches long with a 1/2" to 3/4" tapered opening. The blower exhaust
air is squeezed through this narrow opening which compresses the air into a powerful jet that is
then used to blast debris from the ground, forcing it over to the suction nozzle.
A. DESCRIPTION OF OPERATION
When at sweeping location, start sweeper auxiliary engine and let idle. Lower pick-up
head fully to pavement (lift chains should be slack). Then pull forward a few feet and
allow curtains to fold under pick-up head into the sweep position. Increase sweeper
auxiliary engine speed to desired RPM and begin sweeping. Once sweeper auxiliary
engine speed is increased and the sweeper is moving forward, the pick-up head skid
plates should become firmly sealed against the pavement.
When sweeping operation has been completed, lower engine RPM and continue travel-
ing forward for a few feet to allow any debris under the pick-up head a chance to make it
over to the suction nozzle and be picked up. Before raising the pick-up head, throttle
down sweeper auxiliary engine to idle, then raise pick-up head. When fully raised,
pick-up head should be secured against up-stop feet for sweeper transit.
PICK-UP HEAD MUST BE RAISED FOR TRANSIT!
NEVER BACK SWEEPER WITH PICK-UP HEAD LOWERED UNLESS
EQUIPPED WITH OPTIONAL REVERSE PICK-UP HEAD CHAINS!
