Repair - General
NOTE:
Most repairs of the reach carriage can be
done without removing the carriage from the mast.
These repair procedures require that the carriage is
installed in the mast and the scissor arms are fully
extended.
WARNING
The reach carriage can fall or tip easily and
cause an injury when not installed in the mast.
If the reach carriage 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 that it cannot move on the support.
The support must be strong enough to allow
full extension of the reach carriage without tip-
ping.
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.
NOTE:
It is usually not necessary to completely dis-
assemble the reach carriage. Do only the steps of the
procedures necessary to make the required repairs.
Read and follow the Safety Procedures When Work-
ing Near Mast in the section Mast, Repair 4000
SRM 482, as well as all WARNINGS and CAU-
TIONS.
