B. GUTTER BROOM
The TYMCO Model 600 gutter broom is extremely durable, but should be checked
daily for bristle setting and wear. Only trained personnel should be allowed to service
the gutter broom while exercising caution and obeying all warning decals.
1. Down Pressure Setting - As the gutter broom bristles wear, the gutter broom
counterbalance spring must be adjusted by backing off the spring eyebolt. When
new bristles are installed the spring must be re-tensioned or rapid wear will result
from the broom being too heavy. The gutter broom may not extend to the curb if
spring is not re-tensioned after installing new bristle segments. Furthermore, the
broom components may be damaged due to the broom dragging too heavy and
impacting the curb or other rigid object rather than floating over them as when
spring is tensioned correctly.
2. Torque Motor Shaft - The torque motor shaft rotates at about 100 RPM and
should be inspected several times daily for wire, string, cassette tape, etc. which
may get wrapped around during operation. Remove as soon as discovered to
prevent end shaft seal failure which can cause severe damage to the gutter
broom torque motor.
3. Bristle Replacement - Use only TYMCO replacement segments for highest qual-
ity performance and best bristle wear life. New segments have 14" bristle expo-
sure. Replace bristles when worn down to 6" exposure. Each TYMCO gutter
broom requires four bristle segments, and when newly installed, the broom diam-
eter is approximately 43". Using the gutter broom with severely worn bristles will
cause damage to the gutter broom components such as the disc, hub and torque
motor.
4. Tilt Angles - Consult the TYMCO Parts & Service Manual for details on setting tilt
angles. An optional hydraulic tilt system is available and allows operator to tilt
broom up and down in the curb using a toggle switch located on the sweeper
control panel.
C. PICK-UP HEAD
Refer to Service and Maintenance in the Pick-Up Head Section of this manual or the
detailed service information found in the TYMCO Parts & Service manual. Operator
must use care when driving sweeper not to damage the low positioned pick-up head.
Cutting corners can cause extensive damage to the pick-up head as well as to the
truck driveline components. Do Not back up the sweeper with the pick-up head in
down position!
1. Skid Plate Setting - The pick-up head assembly rides on symmetrical, bolt-on
skid plates using long lasting runners with carbide inserts. The skid plates may be
adjusted for various types of debris (See Dwgs M00771 & M00743) and should
be rotated from one side to the other for extended service life. The skid plate
position is set regardless of curtain length and is not used to compensate for seal
curtain wear. Skid plates are set to sweep a particular type of debris and locked
in position by tightening all skid plate bolts.
NOTE: Do Not lower skid plates when new seal curtains are installed on
bottom of the pick-up head!
