WARNING
To avoid personal injury or death:
• Make sure that the bucket is lowered to the
ground before putting the lift arms in the
“FLOAT” position. Putting the lift arms in the
“FLOAT” position while they are off the ground
will cause the bucket and lift arms to fall and is
extremely dangerous.
• Do not drive the machine forward with the lift
arms in the “FLOAT” position.
To fix the float position, press the float switch and the
control lever can be held in the float position.
