Vehicle System Testing & Adjusting 74
Carriage and Mast Height Adjustment
1. Move the mast either forward or backward so it is
in the vertical position.
2. Lower the carriage completely.
3. On Full Free Lift Full Free Triple Lift and Quad
Lift models, the bottom of the inner mast must be
even with the bottom of the stationary mast.
4. Measure the distance from the bottom of the
inner upright to the bottom of carriage bearing.
5. The measurement (A) must be as follows:
STD.........................................................Zero
FFL, FFTL & Quad...41±1.5 mm (1.61± .06 in)
NOTE: On Standard Lift models the bearing must
be even (flush) with the inner mast. If the above
measurements are not correct, make adjustments
to the chains to get the correct measurement. See
Chain Adjustments in TESTING AND ADJUSTING.
Forks Parallel Check
1. Lift the mast and operate the tilt control lever,
until the top surface of the forks is parallel with
the floor. Place two straight bars, that are the
same width as the carriage, across the forks as
shown. Measure the distance from the bottom of
each end of the two bars to the floor. The forks
must be parallel within 3 mm (.12 in) for Full
Tapered and Polished (FTP) forks, all other forks
6.4 mm (.25 in), for their complete length.
2. If not parallel, determine which one is defective
and replace it.
