PLATFORM-CONTROL BOX
Controls for operating the TB 60 from the
platform are located on the platform-control box,
with the exception of the yellow foot switch which
is on the platform floor.
1. EMERGENCY STOP: Press the large red cap
down at any time, under any conditions, and the
entire machine stops — the engine turns off, the
brakes set, and nothing moves. This switch must
be pulled to its up (or out) position if the TB 60 is
to be controlled from the platform.
2. EMERGENCY POWER: If the engine stops
and cannot be restarted, hold the switch toward
you and a small, battery-powered hydraulic-pump
comes on to supply power for the machine.
Boom movements will be slow and have long lag
times under EMERGENCY POWER.
3. ENGINE SPEED: Leave this switch set on
SLOW unless you want to drive at maximum
speed (see DRIVE RANGE below).
4. BOOM SPEED: This control determines how
fast the main-boom moves in, out, up, or down;
and how fast the platform rotates and levels. Set
it to SLOW until you are very familiar with the
way the machine works.
5. DRIVE RANGE: In LO the TB 60 will only
travel 1 mph (1.6 km/hr). In HI the TB 60 will
travel 3 mph (4.8 km/hr) if the booms are down
and retracted and ENGINE SPEED is set to
FAST. If the booms are up or extended the TB 60
will only travel 1 mph (1.6 km/hr) regardless of
this switch setting. Switching from LO to HI
changes the driving conditions from low speed
and high torque to the wheels to high speed and
low torque to the wheels.
C A U TIO N
Prolonged driving in HI (3 mph, 4.8 km/hr) heats
the hydraulic oil. Periodically check the
thermometer at the hydraulic-oil tank sight-glass.
Do not let the oil exceed 200°F (93°C). Stop the
engine and let the oil cool if necessary.
6. PLATFORM LEVEL: UP rotates the platform
up relative to the end of the tip-boom. DN (down)
rotates the platform down.
7. PLATFORM ROTATE: CW rotates the
platform clockwise (as seen from above) relative
to the end of the tip-boom. CCW rotates the
platform counterclockwise.
8. EXTEND: OUT extends the booms. IN retracts
the booms.
