Steering Switches - JLG TOUCAN 1010 Service Manual

KNOW YOUR TORQUE WRENCH ! Flexible beam
type-wrenches - even though they might have a preset
feature - must be pulled at right angles and the force
must be applied at the exact center of the handle.
Force value readings must be made while the tool is
in motion.
Rigid handle-type torque wrenches are available with
torque limiting devices that can be preset to required
values and which eliminate dial readings.
NOTE
When multipliers and/or special tools are
used to reach hard-to-get-at spots, ensure
torque readings are precisely calculated.
Identification of fastener grade is always
necessary. When marked as a high-strength
bolt (grade 10.9, 12.9 etc.), the mechanic must
be aware that he is working with a highly
stressed component and the fastener should
be torqued accordingly.

5.14 Steering switches

Upper
switches
Lower
switches
Lower switches :
The lower switches limit the steering angle of the
wheels when the mast is raised at more than half its
course (when the limit switch located on the right hand
side of the telescopic mast is activated).
The right hand side lower switch limits the steering to
the right when the steering angle of the right steering
wheel reaches 45°.
The left hand side lower switch limits the steering to
the left when the steering angle of the left steering
wheel reaches 45°.

MAINTENANCE
Upper switches :
The upper switches cut off the drive function when the
mast has been raised at more than half its course
(when the limit switch located on the right hand side
of the telescopic mast is activated) with the steering
wheels initially steered at an angle above 45°. The
wheels need to be straightened to restore the drive
function.
When the mast is fully lowered and the machine is
driven at HIGH speed (
automatically to TORQUE speed when one of the lower
switches is activated (drive speed limitation when the
wheels are steered at an angle above 45°).
When steering the wheels, the lower switches
must be activated before the upper switches
so as the steering limitation occurs before
the drive function cut-off.
