Machine Operating Temperature
Range
The standard machine configuration is intended
for use within an ambient temperature range

Machine Operation
Only operate the machine while you are in a seat.
The seat belt must be fastened while you operate the
machine. Only operate the controls while the engine
is running.
While you operate the machine slowly in an open
area, check for proper operation of all controls and all
protective devices.
Before you move the machine, you must make sure
that no one will be endangered.
Do not allow riders on the machine unless the
machine has the following equipment:
• additional seat
• additional seat belt
• Rollover Protective Structure (ROPS)
Never use the work tool for a work platform.
Note any needed repairs during machine operation.
Report any needed repairs.
Do not operate the machine on ground conditions
that could result in the seat suspension travel stops
being contacted and do not operate the machine at
travel speeds that could result in the seat suspension
travel stops being contacted. Operating this machine
in very rough ground conditions or at travels speeds
not suitable for the ground conditions may result
in excessive seat vertical travel with impact of the
suspension against the travel stops, which may
cause injury. In order to minimize impact loading on
the operator, properly adjust the seat controls for the
operator weight and height. Refer to Operation and
Maintenance Manual, “Seat” for more information.
Carry attachments approximately 40 cm (15 inches)
above ground level. Do not go close to the edge of a
cliff, an excavation, or an overhang.
If the machine begins to sideslip downward on a
grade, immediately remove the load and turn the
machine downhill.
Avoid any conditions that can lead to tipping the
machine. The machine can tip when you work on
hills, on banks and on slopes. Also, the machine
can tip when you cross ditches, ridges or other
unexpected obstructions.
Avoid operating the machine across the slope. When
possible, operate the machine up the slopes and
down the slopes.
Maintain control of the machine. Do not overload the
machine beyond the machine capacity.
Never straddle a wire cable. Never allow other
personnel to straddle a wire cable.
Before you maneuver the machine, make sure
that no personnel are between the machine and
attachments.
Know the maximum dimensions of your machine.
Always keep the Rollover Protective Structure
(ROPS) installed during machine operation.
