Installation
A. PLAN INSTALLATION
Mounting Surface
Winch must be installed on a flat surface, reinforced if necessary, to withstand a
load equal to at least twice maximum working load of winch.
It is the installer's responsibility to carry out all structural tests needed to ensure
that the mounting surface can withstand the load.
Winch Entry Angle of Lifting Rope
Winch entry angle must be 8° with a tolerance of ±2° to avoid rope overrides.

" Socket Head (SH) Bolts (Steel Alloy, 12.9 Class (ISO 898 part 1)
Installation Procedure 2:
Five (5) M6 Hex Head (HH) Bolts (Steel Alloy, 12.9 Class (ISO 898 part 1).
Note:
1/4" Hex Head bolts do not fit in the holes and cannot be used to mount winch.
Harken
®
does not supply bolts to install winch since lengths may vary depending on mounting surface.
It is installer's responsibility to choose correct bolts, taking into account loads they will have to withstand.
Harken
®
assumes no responsibility for incorrect installation of winch or for use of incorrect mounting bolts.
WARNING!
To install winch, use only steel alloy bolts, 12.9 class (ISO 898 part 1). Bolts made of other
materials may not have sufficient strength or may corrode, which can cause winch to pull off mounting
surface suddenly during high loads, possibly resulting in severe injury or death.
WARNING!
Incorrect installation of winch may cause severe injury or death. Consult equipment supplier
if in doubt about correct position of winch.
WARNING!
Failure to use correct number and type of mounting fasteners or failure to ensure correct mounting
surface strength can result in winch pulling off suddenly and unexpectedly during high loads, possibly
resulting in severe injury or death.
Mount winch so drive gear (11 – Pinion Z13) is positioned where rope enters
winch drum. Note:
s
on winch skirt identifies location of drive gear.
WARNING!
Verify entry angle of rope. It must be 8° with tolerance of ±2°, to avoid
rope overrides and damaging winch or making winch inoperable, leading to loss of
control, possibly resulting in severe injury or death.
Winch Location
Winch must be installed in a position to allow sufficient working space around unit, so not to impede
operation of handles.
Winch must be installed in a position to ensure visibility of the lift trajectory by operator at all times.

WARNING!
Mount winch so that drive gear is positioned where rope enters winch drum. Incorrect
positioning of drive gear can weaken winch leading to failure, possibly resulting in severe injury or death.
