OPERATING THE MACHINE
TB18 Plus&20J Plus Operation Manual 7-7 © Apr 2022
FALL HAZARD
The platform level switch can
only be used for slight leveling of
the plaform, improper use may
cause the load/occupant to shift
or fall.
5. Depress the footswitch and meanwhile move
leftwards/rightwards the platform rotate switch to
rotate the platform clockwise or counterclockwise.
6. Depress the footswitch and meanwhile move
upwards/downwards the jib up/down switch to raise
or lower the jib boom. (TB20J Plus)
7. Depress the footswitch and meanwhile move
leftwards/rightwards the main boom telescope/jib
rotate control handle to rotate the jib boom
clockwise or counterclockwise. (TB20J Plus-if
equipped)
To steer：
Depress the footswitch and meanwhile move forward
the drive/steer control handle and press the left/right
side of the thumb rocker switch on top of the handle to
steer left/right.
To select drive speed：
1. The machine in non-operating position can select
from two drive speed modes (high/low speed).
2. In the process of driving, move the drive high/low
speed select switch to select the desired drive
speed.
TIPPING HAZARD
The machine must be driven at low
speed when tilted.
When in operating position, the machine can only drive
at operating speed, operation of the drive high/low
speed select switch will not enable the high speed
mode.
DRIVING ON A SLOPE
TIPPING HAZARD
• Do not operate the machine on
the slope exceeding the maximum
slope rating (5°).
• Do not drive the machine across
the slope exceeding the maximum
side slope rating (14°).
• Do not drive the machine on the
slope exceeding the machine
gradeability.
Before driving on a slope：
1. Determine the gradeability (climbing ability) of the
machine.
Maximum gradeability：
Uphill：45%/24°
Downhill：30%/17°
Side slope：25%/14°
2. Ensure the machine is in stowed position.
3. Ensure the slope grade is within the limits of the
machine gradeability.
NOTICE
Gradeability refers to the maximum permissible
percentage of the slope (or called slope grade as
below) when the machine is on solid ground with
sufficient traction and the platform is carrying only
one person. As the weight of the machine’s platform
increases, the machine’s gradeability reduces.
To determine the slope grade：
