Section 3 – Familiarization
WARNING
Do not operate this MEWP without correct training
and authorization. If you do not obey, there is a
risk of death or serious injury.
WARNING
MEWP Familiarization must be given to a qualified
operator. If you do not obey, there is a risk of death
or serious injury.
WARNING
It is the responsibility of the operator to fully
understand, and follow all instructions and
warnings contained in this operation manual and
on the MEWP. If you do not obey, there is a risk of
death or serious injury.
Read and fully understand the operation manual,
all the warnings, and the instruction labels (refer to
Section 8) on the MEWP.
Do these tasks before the operation:
1. Worksite inspection. Refer to Section 2.4.
2. Daily visual and maintenance inspections. Refer
to Section 4.2.
3. Function tests. Refer to Section 4.3.

Features and devices Section 3 – Familiarization
FAMILIARIZATION
3.4-6 Platform load sensing system
The platform load-sensing system prevents normal MEWP movement when the platform is overloaded and in a
stationary position.
The boom position (extension and angle) has an effect on the platform capacity. Each boom position zone
(high-capacity zone or low-capacity zone) has a different capacity. Refer to the platform capacity label(s) for the
maximum platform capacity of each zone.
WARNING
If the platform is overloaded because of contact with an overhead obstruction, do one of the steps that
follow:
▪ Remove the obstruction from the platform. Then after four seconds, you can operate the normal
functions.
▪ Use the emergency-power unit to release the platform from the obstruction (refer to
Section 3.4-7).
WARNING
Fall hazard. Do not try to free a snagged platform with the base controls until you remove all personnel
from the platform. If you do not obey, there is a risk of death or serious injury.

* Min: Minimum MEWP weight (Unloaded platform, no options/attachments)
Max: Maximum MEWP weight (Platform loaded to capacity with options/attachments)
** Wheel Load is the weight that can be experienced on one wheel.
Note: This is more than 25% of the machine weight due to possible weight distribution over the machine and platform.
*** LCP: Local Concentrated Pressure is a measure of how hard the MEWP presses on the area in direct contact with the floor/tire.
OFL: Overall Floor Load (Pressure) is a measure of the average load the MEWP imparts on the whole surface directly underneath
the chassis. This has been calculated by dividing the MEWP weight by the overall floor area occupied by the MEWP (on wheels).
Note: The floor covering (e.g., tile, carpet, etc.) or the structure (e.g., beams) of the operating surface must be able to withstand
more than the values indicated above.
NOTE
The LCP or OFL that an individual surface can withstand varies from structure to structure and is
generally determined by the engineer or architect for that particular structure.
