WARNING: Never exceed the maximum additional

and/or property damage may result.
When using PRE Series extensions and/or PRS Series spacers,
always obey the following rules:
• For loads up to 60 tons [54 metric tons]: Any two PRE Series
extensions may be included in the stacking arrangement,
provided that the maximum stack height (See Table 5) is not
exceeded and the following exceptions are observed:
1) Jack models PREMB06014L, PREMI06014L and
PREME06014L: Only one PRE18 extension can be included
in the stacking arrangement.
2) All jack models ending in “16L”: Only one PRE11,
PRE14 or PRE18 extension can be included in the stacking
arrangement.
3) All jack models ending in “27L”: Extensions PRE14 and
PRE18 cannot be included in the stacking arrangement.
These extensions are designed for short stroke jacks only
(models ending in “14L” and “16L”).
• For loads over 60 tons [54 metric tons], or strokes over 14
inches [356 mm]: Only one PRE Series extension and one PRS
Series spacer can be included in the stacking arrangement.
• Never exceed 3 inches [76 mm] in total spacer height.

5.7 Load Caps
A non-swivel load cap is included with the jack as standard
equipment. A swivel load cap is available as an optional
accessory. Refer to Table 6 for a list of load cap model numbers.
IMPORTANT: Use a swivel load cap to properly engage angled
lifting points. A swivel load cap should always be used when the
amount of misalignment between the standard load cap and the
lifting point is too large to be compensated for by use of plywood
or other suitable high-friction compression material alone.
