GROUND-CONTROL PANEL
Switches for operating the TB 60 from the ground
are located on the right side of the machine
behind the small door.
NOTE: The number of each switch below
corresponds to the switch’s call-out on the
next page.
1. EMERGENCY STOP: Press the red cover
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 up for anything on the machine to work.
2. EMERGENCY POWER: If the engine stops
and cannot be restarted, continuously holding
this switch down activates a small, battery-
powered hydraulic-pump that supplies
emergency hydraulic power for the machine.
Boom movements will be slow and have long lag
times under EMERGENCY POWER.
3. SELECTOR SWITCH: Must be in the
GROUND position for the ground-control panel to
work. Must be in the PLATFORM position for the
platform controls to work.
4. BOOM SPEED: This control determines how
fast the main boom moves in, out, up, or down.
Set it to SLOW until you are very familiar with the
way the machine works or if the platform is
working in dangerous or cramped surroundings.
5. GROUND OPERATION: You must manually
hold this switch up any time you use one of the
five platform-moving switches (see box at right)
to move the platform. Holding the switch up
increases the engine speed and activates the
platform-moving switches in preparation to do
work.
6. MASTER: This switch works like an
automobile ignition switch. Hold it at START until
the engine starts then release it to ON. If the
engine dies in ON, the key must be turned to
OFF before it will go back to START.
NOTE: On some machines you might have to
pause about three seconds in the ON position
before going to START so the starter can
engage.
Turn the MASTER switch to OFF if the platform
is to stay in a particular position for a long time.
That will turn the engine off and save fuel.
7. ENGINE SPEED: Leave the switch set on
SLOW unless you need to warm the engine and
hydraulic oil up FAST. Return to SLOW after
warm-up.
8 through 12 are the platform-moving switches.
Each is a three position, momentary contact,
normally-off switch.
8. TURNTABLE SWING: CW rotates the entire
turntable clockwise (as seen from above). CCW
rotates the turntable counterclockwise.
9. PLATFORM ROTATION: CW rotates the
platform clockwise (as seen from above) relative
to the end of the tip-boom. CCW rotates the
platform counterclockwise.
10. PLATFORM LEVEL; UP rotates the platform
up relative to the end of the tip-boom. DN (down)
rotates the platform down.
11. BOOM EXTENSION: OUT extends the
booms. IN retracts the booms.
12. MAIN BOOM ELEVATION: UP raises the
base-boom. DN (down) lowers the base-boom.
13. (OPTION - FUEL): Before starting the engine
set the FUEL switch to GASOLINE or L.P.-GAS
depending on which you want to use. If you
select L.P.-GAS be sure to open the valve on top
the LP gas tank. To switch fuels with the engine
running, see the DUAL FUEL SYSTEM decal on
the inside of the ground-control panel door.
