3. Safety Precautions
This forklift is not equipped with a riding device. If you ride the forklift, you may
fall and suffer injury.
If the forklift runs with the cargo being pressed, the person who presses the
cargo may collide with the forklift and a surrounding object, resulting in injury.
If the forklift overrides objects scattered on the floor, the forklift is inclined,
causing the cargo to fall. Do not override scattered objects.
If it is inevitable to run the forklift in a place where it may collide with a
surrounding person or fall, allocate a guide to ensure safety.
When a guide is allocated, a guide sign should be discussed in advance.
If work starts without discussion about a guide sign, the worker may confuse the
sign, causing collision and fall accidents.
If the forklift runs to the back (toward the fork) with cargo being stacked to a
height that blocks operator’s view, the operator cannot see the area at the front of
the cargo and fails to avoid collision with a person or object, resulting in a
collision accident.
14
Do not press cargo during transfer.
Do not ride the forklift.

3. Safety Precautions
If the forklift is overloaded beyond the maximum allowable load weight, the forklift
overturns. If the forklift overturns, the forklift and dropped cargo may collide with
a person, resulting in serious injury.
If a pallet is not inserted to the root of the fork, the forklift becomes unstable and
may overturn. Also, the pallet may fall from the fork.
If the fork width is not adjusted according to the pallet being used, the pallet
becomes unstable, causing the cargo to fall.
Stack cargo on a pallet so that it will not collapse. If the cargo collapses, the
dropped cargo may collide with a person, resulting in injury.
15
If the center of gravity of load exceeds 500 mm from the root of the fork, the
maximum allowable load weight of this forklift will be reduced. Overloading the
forklift beyond the maximum allowable load weight causes the forklift to overturn.
If the forklift overturns, the forklift and dropped cargo may collide with a person,
resulting in serious injury.
During loading into a truck or container, if the truck or container unexpectedly
starts, the forklift may fall. Before loading the forklift into a truck or container,
make sure that the truck is securely parked (with parking blocks, etc.).
