slowly. Do not allow anyone near the machine.

replace it immediately with the correct control pattern card.

SAFETY RULES FOR CHANGING MACHINE DIRECTIONS
q
Always operate the machine only when seated.
q
Do not allow anyone apart from the operator to ride on the
machine.
q
Check that the travel alarm works properly.
q
Always lock the door and windows of the operator's compart-
ment in position (open or closed).
On job sites 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.
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
Before travelling, sound the horn to warn people in the area.
q
Before travelling, check again that there is no one in the sur-
rounding area, and that there are no obstacles.
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 steer-
ing is reversed). Be extremely careful when operating the
machine in this situation.
