GENERAL
Read and follow the Safety Procedures When Work-
ing Near Mast as well as all WARNINGS and CAU-
TIONS.
NOTE:
These procedures are for both the two-stage
and three-stage mast assemblies. Move the lift truck
to an area with a smooth, level floor to make sure the
adjustments are accurate.
The mast weldments must be aligned so that they are
parallel to each other during operation. Keeping the
weldments parallel will have the result of smoother
operation and wear.
