Rocker Arm and Pull Rods
REMOVE
WARNING
When performing service that will require the
rocker arm to be removed, the main frame and
fork frame must be securely supported so that
they cannot lower or tilt when the linkage is dis-
connected.
WARNING
Batteries are heavy. Use care when working near
or moving to avoid injury. DO NOT put hands,
arms, feet, and/or legs between the battery and a
solid object. Make sure the capacity of the lifting
device and spreader bar is greater than the weight
of the battery. The weight of the battery is nor-
mally shown on the battery case. The maximum
battery weight is shown on the lift truck name-
plate. The spreader bar must NOT be made of
metal or it must have insulated straps.
1. Move the lift truck to a safe and level area.
2. Use the lift button to raise the forks to maximum
height.
3. When performing service that will require the
rocker arms or the upper links to be removed, put
a solid wood or metal block under each side of
the main frame, near the rocker arms. The blocks
must be thick enough to just fit under the main
frame. The main frame must not lower or tilt when
the rocker arms or upper links are disconnected.
Put blocks under both forks and on both sides of
the drive tire. See the section
