How To Put A Lift Truck On Blocks
WARNING
The lift truck must be put on blocks for some types of
maintenance and repair. The removal of the following
assemblies will cause large changes in the center of
gravity: mast, drive axle, engine and transmission, and
the counterweight. When the lift truck is put on blocks,
put additional blocks in the following positions to main-
tain stability:
1. Before removing the mast and drive axle, put
blocks under the counterweight so that the lift
truck can not fall backward.
2. Before removing the counterweight, put blocks
under the mast assembly so that the lift truck
can not fall forward.
The surface must be solid, even, and level when the lift
truck is put on blocks. Make sure that any blocks used
to support the lift truck are solid, one piece units.
NOTE:
Some lift trucks have lifting eyes. These lift points
can be used to raise the lift truck so that blocks can be
installed.
How To Raise The Drive Tires (See FIGURE 6.)
1. Put blocks on each side (front and back) of the steering
tires to prevent movement of the lift truck.
2. Put the mast in a vertical position. Put a block under
each outer mast channel.
3. Tilt the mast fully forward until the drive tires are raised
from the surface.
4. Put additional blocks under the frame behind the drive
tires.
5. If the hydraulic system will not operate, use a hydraulic
jack under the side of the frame near the front. Make sure
that the jack has a capacity equal to at least half the
weight of the lift truck. See the Nameplate.
How To Raise The Steering Tires (See FIGURE 6.)
1. Apply the parking brake. Put blocks on both sides (front
and back) of the drive tires to prevent movement of the lift
truck.
