Introduction Performance
Introduction
Performance
Spinlock are the experts in high load rope holding. These
high load models are designed to match the advances in
high strength ropes. With their unique wedge action they
will hold expensive sheets and halyards safely and securely,
with low risk of damage.
Products in the high load range include the ZS Alloy, ZS
Carbon, ZS Open Jammers and XX Powerclutch, holding
ropes from 8mm to 32mm and loads up to 12000kg.
High Load products included in this instruction booklet
include:
The ZS and XX range of clutches and jammers are designed to generate
high compressive loads on the rope to ensure the core bears the greater
part of the load without over stressing the polyester or other fibres of
the outer braid. The structure of the jammers and clutches can withstand
loads beyond the stated max holding load. The data shown, represents
the maximum SWL we recommend for each product for a given diameter
with polyester covered ropes.
The actual load achievable can vary considerably according to the quality
and construction of the rope used. Before selecting the rope to use in
the product, check:
• The actual measured diameter under load.
• That the rope cover includes polyester - Vectran, HMPE (Dyneema,
Spectra) or PBO cannot be gripped on standard jaws, unless
blended with polyester.
• The cover is a close t on the core with an interface layer or bre
coating. Nominal section should be round.
• Sleeved areas are fully pre-tensioned with smooth entry and exit
tapering.
• The load rating for the rope and safety factor recommended by the
rope manufacturer.
Recent development in rope manufacture has centred on the use
of blended covers, where high tech fibres such as Aramid, Technora,
Dyneema or Vectran are co-braided with polyester or polypropylene.
Whilst hardwearing, with a high degree of heat resistance, these covers
can be harder to hold in clutches or jammers compared to polyester
covered lines. Contact the Special Projects Team for advice on new
digital custom jaw surfaces to suit specific blended covers or see
page 34 for spares and upgrades.

ZS Alloy Jammers and ZS Carbon Jammers
How to use
How to use
ZS Alloy / Carbon installation
pages 16-17 maintenance pages 22-23 spares pages 34-35
The jammers are relatively simple to operate, but because of the high loads
it is important to fully understand their function before use.
To Open : Pull handle out until latch clicks. The latch must be fully engaged
to hold the jaws open.
The rope can now be inserted and run freely in either direction. On large
diameter ropes it may be easier to lead the rope through the jammer with
the jaws removed. (see maintenance).
To lock line : Hoist sail and tension with winch. Before easing load off
winch, release the latch in the handle and push the jaws forward onto the
rope. Continue to apply firm pressure on the handle as the load is eased
off the winch onto the jammer. Once the jaws are fully engaged onto the
rope, they will slide forward a few millimeters as the full load is secured.
To Re-Open : The full load in the rope must be returned to the winch
before the jammer can be opened. Never attempt to the open jammer
without transferring the load back onto the winch. Only when the load
is secured on the winch is it safe to pull the handle back and engage the
latch. The jaws are now fully locked open and the rope can be controlled
from the winch to run freely through the jammer.
Note : For safety reasons ZS Jammers can only be released after the rope
load has been transferred to the winch drum.

ZS Open Jammer
How to use
How to use
ZS Open maintenance
pages 22-23 spares pages 34-35
The ZS OPEN can be locked onto any loaded line, the perfect solution for
peeling spinnakers, headsails, reefing and dealing with an emergency.
1. Secure strop to padeye or winchbase of sufficient strength and aligned
as close to the line of load as possible.
2. Open the sideplate and engage the ZS OPEN onto the line. Then close
ensuring full engagement of the sideplate latch.
3. Slide jammer along the line so the strop is tight (this reduces runout)
and engage jaws, by releasing the jaw latch.
4. Carefully release the original loaded line from winch so the strop and
ZS OPEN jammer take the load.
Releasing the ZS Open Jammer
The ZS Open Jammer is released by holding the handle and sliding the
body forward, not pulling the handle back. Ensure there is enough slack in
the strop to allow disengagement of the Jaws.
Important Notes
Ensure prior to transferring a load that the:
• Coverplate is fully engaged onto the main body
• Latches are locked into the location pins
This ensures that the burst loads are shared by both side plates. Failure to
do this will cause the body to permanently deform and the cover plate will
no longer t. If the unit should be overloaded the white PTFE bearing will
show signs of deforming at its contact with the upper and lower faces of
the body.

XX0812, XX0812/L Clutch
How to use
How to use
XX0812 installation
pages 20-21 maintenance pages 24-27 spares pages 34-35
The XX holds loads 50% higher
than any conventional clutch
and is smooth and controlled
to release. Optimised for high
performance 8-12mm diameters,
the XX fills the critical load
holding gap between clutches
and high load ZS jammers.
As well as the standard clutch, a
Lock Open version, the XX0812/L,
is also available which allows the
line to run freely in both directions
with the handle closed, important
for spinnaker and mainsheet
applications where locking off
is only occasionally needed. The
XX0812/L also features an automatic
jaw release when the load is taken
on a winch. A standard XX can be
upgraded to a Lock Open version
with XX-MLDG or XX-LCK kit.
Line feeding into the XX0812 :
Using a long screwdriver, place shaft
through front bullseye and locate
tip on front face of lower jaw. Push
backwards until the jaw stops. With
the jaws in this position raise and
fully open the handle. This locks the
jaws back at their biggest clearance
and allows easy threading of your
new rope.
This process is not necessary for the
XX Lock Open Version.
Line feeding into
the XX0812
Safety Note : In stronger winds,
rope damage can be caused
releasing a highly loaded
line. This can be prevented by
transferring the rope load to
the winch before release.
XX0812/L Lock Open Clutch Operation
1. With the lock open latch in the UP
position the line runs freely through the XX
2. When the latch is pushed DOWN with the
handle closed, the line is held secure
3. To release the line, the handle can then be
opened, OR
4. With the handle in the closed position,
move the lock open latch to the UP
position. When the load is taken securely
on a winch the jaws will automatically
release, allowing the line to run free, with
the handle still in the closed position. The
jaw will remain open until the latch is
returned to the down position, even if
the handle is cycled.
With your new rope threaded you
can now close the handle. As the
handle closes, the XX clutch will
automatically engage the rope.
Release : As a safety feature, no
release action begins until the handle
is rotated beyond 60 degrees.
To protect the user and rope fibre,
normal hand pressure will not
release the rope above this load.
Important : Always start the release
process with the handle in the closed
position for full release efficiency.
If at any time you only part open
the handle we advise completely
opening and closing (cycling) the
handle, with the line secured on the
winch, to ensure the mechanism is re-
set for full release next time. Failure
to do this will result in poor holding
power and worn jaw surfaces.
Sleeving : Secondary sleeving
(internal or external) of the
rope significantly improves the
performance levels of any clutch
or jammer. Any external sleeving
should be a very tight fit. If you are
going to sleeve your rope, ensure
that the overall diameter does not
exceed 12mm and has a taper to
run freely through the clutch. Core
inserts provide the smoothest
transition for fast line speed
applications.

If fitting to the deck, install the jammers forward of the winch, close enough
for easy operation of the handle and latch, ensuring enough space is left
behind the product for removal of the jaw assembly for maintenance. The
jammers are provided with studs (A4-70 stainless steel) in a pattern. This
helps spread the load into lightweight composite decks or masts.
They are a tight t to ensure good thread engagement. Drilling templates
for deck layout are provided with the product.
Warning : The studs should be screwed a maximum of 15mm into
the body. Over tightening may damage internal bearing surface
Side Mounting : Replace the six body fasteners with longer bolts. These
can be inserted from either side by removing the round insert nuts. These
must be at least A4-70 stainless steel bolts if the maximum safe working
loads are to be reached. Refer to specication chart (page 7).
Double check the hole pattern before drilling. The pattern is not
reversible.
Mast Mounting : Mast mounting plates are available, see page 34 for
details. CAD templates can be download from:
www.spinlock.co.uk/cadlibrary
The Jammers are not designed to withstand high side loads. If the lead
angle to the winch is greater than 10 degrees, fit lead blocks or organisers
aft of the jammers. Contact the Special Projects Team for details of our TS
High Load Aft Organiser.

1. Mount the ZS-RLB in it’s preferred location using M5 fasteners.
2. Choose a suitable very low stretch control line 2-4mm which can be
spliced.
2. Attach the control line to the jaw set using a thumb knot or similar -
see diagram below. Remove rear block and jaw step ( see page 22).
3. Thread the control line through the spring and rear blockand fasten
the rear block into place.
4. With the control line cut to approximately the correct length, splice the
control line to the eye of the RLB-Spring using an adjustable splice.
5. Ensure the control line has a free, un-interrupted, low friction run
to the jammer. If necessary use bulls eyes or blocks to ensure a
smooth run.
6. With the jaw set loaded on the correct diameter line and the RLB
closed adjust the control line splice so it is just taut.
7. Check operation as described (see page 12 and 13). Some adjustment
may be necessary before making the splice permanent.
8. Changes in the rig set-up or line diameter will require the control line
splice to be adjusted.

1. Align the clutch with the required rope lead, checking height and
minimising the angle of alignment.
2. Drill two holes to suit the M8 fasteners using template (never drill
through the clutch). For spars, etc. where no access is possible, use an
M8 tap to thread the surface material, ensuring the material has
sufficient strength to carry the full clutch load, the fasteners must be
replaced with M8 A4-80 stainless socket cap or CSK Machine screws.
3. Check each fastener (already pre-assembled into clutch) to make certain
that its hexagonal head is properly seated in its locking moulding.
4. Fasten clutch firmly after sealing upper threads with silicone sealant.
In through-deck applications any excess thread can now be ground off.
To access the fasteners : The XX0812 is supplied tted with High
Tensile A4-80 stainless steel hex head fasteners so access is unlikely to be
needed.
If you want to fit your own fasteners, you will only need to remove the rear
end moulding to gain access to the aft fixing position.
The forward fastener can be accessed from above (see Diagram 1). The
simplest way to remove this fastener is to remove the nut and washer and
turn the product upside down. The M8 fastener can now be removed.
For Lock Open Versions, ensure the lock open latch is in the down position.
Lift handle 50mm to gain access to the M5 Allen screw on the top surface
that retains the rear moulding. Remove this screw. (See Diagram 2).
Hold rear cover at top and rotate and pull out from the top (See Diagram 3).
Pull the complete rear moulding and jaw assembly free from the body (See
Diagram 3).
The fastener will now be visible. Leave the retaining moulding in place.

Spinlock ZS Jammers are made from the highest quality materials for
durability and low maintenance in a harsh marine environment.
ZS Jammers are carefully designed for easy and regular servicing at sea. Their
life and performance will be improved if regularly flushed with fresh water.
The jaws can be easily removed for inspection and replacement:
For ZS Alloy and ZS Carbon
• Remove the screw securing the rear block.
• Remove rear block.
• Pull out the handle and jaw assembly.
For ZS OPEN
• Open the sideplate to allow removal of the jaw assembly -
compress jaws together to extract sideways.
ZS Alloy, ZS Carbon and ZS Bonded
All
• Check for excessive wear on the grip surface - the black anodised
surface, if worn, will have silver aluminium showing through.
• Check condition of the white bearings surfaces are clean and smooth.
Replace if necessary.
• Ensure all internal faces are clean and smooth.
The white jaw bearings should be lubricated only with silicone grease.
Do not use mineral oil or solvent based lubricants like WD40.
Replacement jaw sets must be installed with grease provided.

General maintenance
Full Servicing
XX0812 how to use
pages 14-15 installation pages 20-21 spares pages 34-35
General maintenance:
Three Simple Steps – flush, drain and lubricate
1. The internal mechanism should be regularly flushed out with fresh
water through the end bullseyes, and the handle pivot area.
2. Check that the lower ‘drainage’ holes in both end mouldings are clear
of any debris. This will help reduce the accumulation of any rope debris
building up inside the product.
3. Lubricate handle pivot areas with a silicone grease. Unless this simple
procedure is carried out regularly, the specified performance will not be
achieved. Take care not to contaminate rollers or jaw surfaces with any
lubricant.
Note : Any decrease in performance is usually caused by lack of
maintenance and servicing. The XX0812 relies on the smooth running of
2 sets of roller bearings for maximum performance. The rollers and their
‘running’ surfaces must remain as clean as possible.
Removal from deck
If removing the XX0812 from the deck, care must be taken to ensure
the fasteners do not damage the internal mechanism and plastic rear
moulding. Do not hammer from below.
Watch the XX Servicing Video at www.spinlock.co.uk
Full servicing and Jaw Replacement:
The clutch should be given a thorough service periodically to ensure
maximum performance is maintained. The clutch mechanism is fully
accessible whilst attached to the deck - even with other clutches banked
alongside - by the following steps.
If upgrading jaws from a Pre 2010 XX0812, then part XX-Kit is required.
See www.spinlock.co.uk for full upgrade instructions, including video
from the Pre 2010 Model.
1. Remove the rope from the clutch.
2. For Lock Open Versions, ensure the lock open latch is in the
down position.
3. Lift handle 50mm to gain access to the M5 Allen screw on the top
surface that retains the rear moulding. Remove this screw.
4. Hold rear cover at top and rotate and pull out from the top.
5. Pull the complete rear moulding and jaw assembly free from the body.

consider upgrade to XX-Roll+. Ensure rollers cages are re-attached in
correct orientation.
Jaw Bearing Surfaces - ensure that both are clean and smooth.
Jaw Grip Surfaces - clean off any rope debris. Check for excessive
wear on the grip surface. If the black anodised surface has aluminium
showing through, replace with a new XX-Jaw Assembly.
Jaw Spring - should be able to hold jaws apart, be a smooth shape
and located on either side of the top jaw.
Jaw Linkplates - check these are attached to both sides of both jaws
with pins and secured by both pins. Ensure free movement of link
plates/pins in jaws.
Release Pin - located centrally in top jaw. Check for any signs of
surface wear.
Clutch Body - flush clean inside, paying particular attention to the
upper and lower roller surfaces, the two drainage runs in the base and
their exits at the end mouldings.
Handle - do not remove this from the body. Check that the operation
holds the handle in the closed and fully open position (via the leaf
spring mounted at the front of the wedge). Lubricate pivots with
silicone grease.

Power Button
• Turn the cell ON by holding down the power button until the screen
comes on. The cell will read load instantly and does not need to be
‘unloaded’ when turned on.
• The load reading will update continuously until 6 minutes has passed
when the unit will automatically power down.
• To turn OFF manually press and hold until the screen goes past ‘Zer’ to
OFF then release the button.
Page Button
• Use this button to switch between TRACKING, PEAK and PEAK
READING modes.
• To enter PEAK press and hold down the page button until the screen
ashed between P and a reading.
• In PEAK mode the unit will remain ON until the battery runs out unless
turned OFF.
• To read the PEAK load hold down the page button until PPP ashes
intermittently with the reading.
• Return to TRACKING mode by holding down the page button. This
resets the PEAK READING to zero.
• BASIC INSTRUCTIONS ARE SHOWN ON THE BATTERY COVER
Zeroing
• From time to time it may be necessary to ZERO the reading due to
climatic conditions. To ZERO press and hold the POWER button and
release when ‘Zer’ appears on screen.
Overload
• If the screen ashes OL in any mode the unit has experienced a
signicant overload and will require re-calibration.
• OVERLOADING 200% OF SWL WILL RESULT IN PERMANENT
DAMAGE TO LOAD CELL
• A calibration certicate is available and valid for 12 months. The unit
must be returned to Spinlock for re-calibration.
Battery Life
• The PP3 9v battery supplied with the unit will last between 2 and 6
hours depending on the range of load measured.
• When the battery power is low the decimal place will start to ash.
• VERY LOW VOLTAGE BATTERIES MAY GIVE INACCURATE
READINGS.
• STORAGE WITH BATTERY CAN RESULT IN LEAKAGE AND
DAMAGE.
Battery Replacement
• To change the battery carefully unscrew the 3 at blade stainless steel
screws with an appropriate sized screw driver.
• Lift of the plastic battery cover and place down without disturbing the seal
• Lift out and detach the battery without straining the wires.
• Clip on a new PP3 9v battery and place inside the compartment with the
battery terminal at the same end as the wire exits the load cell body.
• Replace the plastic battery cover and carefully locate the 3 bolts before
screwing evenly until the seal is compressed an even amount all round.
• DO NOT OVER TIGHTEN THE SCREWS
