Snorkel TB120 2001 - Manual (Page 36)

7. OPERATION
7 - 1 P/N 0191914
Read and understand all the previous chapters in
this manual before you begin to operate a
TB120.
Dual-fuel is the only optional equipment
discussed in this chapter. For operation of other
optional equipment, see the "OPTIONS" chapter.
T
CONTROL STATIONS
A TB120 can be operated from the ground-
control box or from the platform-control box.
There are basically two differences between
ground-control and platform-control operations,
both are safety related:
1. The ground-control box can override the
platform-control box at any time. If a person
operating the machine from the platform
becomes incapacitated, a person on the
ground can always take over machine control.
D A N G E R
Do not attempt to operate the TB120 ground
controls when the platform, booms, or any
other conducting part of an TB120 is in
contact with energized electrical wires or if
there is an immediate danger of such contact.
2. The TB120 can only be driven from the
platform-control box. The wheels cannot be
made to move from the ground-control box.
This prevents ground-control operators from
running over themselves.
T
EMERGENCY STOPPING
To stop a TB120, push either of the two
EMERGENCY STOP buttons (1) (2) in. (For a
complete discussion of the EMERGENCY STOP
switches, see the “CONTROLS” chapter.)
T
STARTING FROM THE GROUND-
CONTROL BOX
Before you begin to operate the TB120 a
qualified operator must perform the "DAILY
INSPECTION & MAINTENANCE" described in
the chapter by that name in this manual.
‰ Pre-start Conditions
After the DAILY INSPECTION & MAINTENANCE
has been performed, put the TB120 into its pre-
start conditions. Pre-start conditions for starting
from the ground-control box are:
1. Set the BATTERY switch (1) to ON and look
to see that the AUX. BATTERY circuit breaker
has not popped out (close the battery-
compartment door).
2. Check the circuit breakers (2) to see that none
has popped out.
NOTE: You do not need to check the circuit
breakers on the platform-control box.
3. Set SELECTOR SWITCH (3) to GROUND.
4. Pull EMERGENCY STOP (4) out.
5. Set ENGINE THROTTLE (5) to LO.
6. Set BOOM SPEED (6) as shown.
7. Set BOOMS/AXLES SWITCH (7) to BOOMS.
