OPERATING THE MACHINE
GTZZ14EJ&16EJ Operation Manual 7-7 © Dec 2021
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 (5°).
• 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: 30% (17°).
Maximum gradeability:
Uphill: 30%/17°
Downhill: 30%/17°
Side slope: 9%/5°
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:
1. Use a carpenter’s level, a straight piece of wood (at
least 1 m [3.3 ft] long) and a tape measure.
2. Measure the height H and length/distance L of the
slope.
Figure 7-5
3. Slope grade= H/L x 100%.
NOTICE
The machine must not drive for over 2min on the
maximum permissible slope grade to prevent the
tires running suspended.
