PICK-UP HEAD
The pick-up head is the most important component of the TYMCO MODEL 500X 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 blower RPM.
3. Increase blower RPM 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 12" 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" 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 ex-
haust air through an elongated pressure nozzle called the Blast Orifice. The blast orifice open-
ing is 87" long with a 1/2" to 1" 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 de-
bris from the ground, forcing it over to the suction nozzle.
OPERATION
1. Before sweeping the operator must check that the sweeper is properly prepared. The
operator should read the Model 500X Operator’s Manual to become familiar with all
aspects of his duties regarding this sweeper. Read the manual first!!!
2. Start the auxiliary engine, and turn on the warning lights.
3. Hold the toggle switch labeled “Pick-Up Head” in the DOWN position until the pick-up
head cylinders are fully extended. When released, the switch will return to the neutral
position.
4. With the pick-up head fully lowered, pull the truck forward a few feet to fold the pick-up
head curtains under into the sweep position. Turn the required gutter broom(s) on by
engaging the gutter broom switch in the DOWN position.
5. Turn the water system switch to the ON position and turn on the desired water nozzles.
NOTE
: The water will not turn on until after the blower is on.
6. Engage the blower rpm switch to the UP position to turn the blower on and increase the
blower rpm.
