LOADING AND UNLOADING OPERATION
The following is the explanation how to operate the fork but it does not explain all of the occasions. It may vary
according to the work situation.
Perform the operation of the fork by the most safe and efficient way in each situation.
PICK UP LOAD
• Do not perform rapid turning, rapid acceleration, nor rapid deceleration when carrying the load. Oth-
erwise, the load may fall or the machine may become inclined.
