Intended use
The Harken integral hydraulic backstay adjuster is designed for
use on sailboats 30 - 60' (9 -18 m). When ordering, always have
your choice confirmed by a Harken representative or other sailing
professional. The limited warranty does not cover use of product
outside of normal sailboat applications.
This user manual contains important information for the correct
use of the Harken integral hydraulic backstay adjuster. Read all
instructions carefully before use. If you do not understand these
instructions, contact Harken. Do not use the integral backstay
adjuster unless you have a sufficient level of sailing training and
experience.
WARNING! Hydraulic adjuster cylinders are
capable of exerting very high loads and can break
associated components. Inspect all standing
backstay and forestay rigging components
to ensure they are in good condition. Failure
to inspect components may result in sudden
breakage at high loads.
