To remove and replace load rollers, wear
plugs, weldments, or lift cylinders, it is necessary to
remove the two-stage mast assembly from the truck.
Reach Assembly Repair
NOTE:
Most repairs of the reach assembly can be
done without removing the reach assembly from
the mast. These repair procedures require that the
reach assembly is installed in the mast and the
scissor arms are fully extended.
WARNING
The reach assembly can fall or tip easily and
cause an injury when not installed in the mast.
If the reach assembly cannot be installed in a
mast during repair, make sure the rear frame
is fastened to a support that cannot move. The
rear frame must be in the same position as it is
in the mast. The rear frame must also be fas-
tened so it cannot move on the support. The
support must be strong enough to allow full ex-
tension of the reach assembly without tipping.
WARNING
Hydraulic oil is hot after system operation and
can cause burns. DO NOT disconnect any hy-
draulic lines of the system until the oil for the
system is cool.
CAUTION
Make sure the lift truck is in a location that is
level and has access to a crane or other lifting
device before doing any repairs on the reach
carriage.
It is usually not necessary to completely disassemble
the reach assembly. Do only the steps of the proce-
dures necessary to make the required repairs.
