Section 3 – Familiarization Features and devices
3.4-2 Drive speed
The drive speed depends on the MEWP conguration (lowered travel position/elevated travel position). When the
MEWP is in the elevated travel position, the speed is slower than the speed in the lowered travel position. Refer to
Section 7.4.
3.4-3 Drive direction
The drive function operates in relation to the general orientation of the turret counterweight on the chassis (i.e.,
when the controller handle is forward, the counterweight faces forward). Thus, the MEWP will move in the general
direction of the controller handle movement.
3.4-4 Tilt switch
The tilt switch is in the base control console. When the MEWP tilts more than a predetermined limit:
▪
an alarm makes a sound
▪
a light illuminates
▪
the boom movement and drive functions are disabled (refer to Section 3.4-5).
WARNING
Tip-over hazard. When the MEWP tilts more than a predetermined limit, the alarm makes a sound, and
the light illuminates. The platform must be lowered and retracted immediately. Refer to Section 6.2 for the
instructions on how to recover from an inclined position. If you do not obey, there is a risk of death or
serious injury.

at the limits of the lowered position, the MEWP will be in the “tilted while elevated” condition.
