SAFETY RULES FOR CHANGING MACHINE DIRECTIONS 2
q
Before traveling, set the machine so that sprocket (1) is
behind the operator's seat.
If sprocket (1) is in front of the operator's cab, the machine
moves in the opposite direction from the operation of the
lever (front and rear travel is reversed, left and right
steering is reversed). Be extremely careful when operating
the machine in this situation.

Before travelling, check again that there is no one in the
surrounding area, and that there are no obstacles.
q
Before travelling, sound the horn to warn people in the
area.
q
Always operate the machine only when seated.
q
Do not allow anyone apart from the operator to ride on the
machine.
q
If there is an area to the rear of the machine which cannot
be seen, position a signal person. Take special care not to
hit other machines or people when turning or swinging the
machine.
q
Check that the travel alarm works properly.
q
Always lock the door and windows of the operator's
compartment in position (open or closed).
On jobsites where there is a hazard of flying objects or of
objects entering the operator's compartment, check that
the door and windows are securely closed.
Always be sure to carry out the above precautions even when
the machine is equipped with mirrors.
