There is a small hole on the side of the

base of the Head that can be used to

apply greater leverage for installing or

removing the Head from your tripod.

The hole is designed to accommodate

a 5/32 hex key (commonly used by our

customers to attach quick-release plates

to lenses & cameras). Note: The hex key

is only used as a leverage arm, it does not engage a fastener

inside the leverage hole (the hole is not threaded). If you do

not have an appropriate sized hex key, any strong metal rod

that will ﬁt into the hole can be used (e.g. a small screwdriver).

Prerequisite: In order to attach your lens to the Sevenoak

Gimbal Head, it must be ﬁtted with an Arca-Swiss style quick

-release plate or foot (see details below).

In order to attach your lens to the Sevenoak Gimbal Head, it must

be ﬁtted with an Arca-Swiss style quick-releaseplate or foot (sold

separately). We oer a line of such plates. For more information

see our catalog or website: www.sevenoak.biz(click on “Lens

Plates”).

We strongly recommend using Sevenoak plates because we

carefully match your lens with the appropriate size plate that

Position the Head’s platform at its

lowest position and level to the

ground. Tighten the Head’s tilt knob.

Mount your lens (with camera body

attached). Stand behind the

lens/camera setup and grab the

camera body as if you are going

to take a picture.

Step 1: Tighten the tilt knob of the

swing arm-make sure that the Head’s

platform is level so that the Head is

stable while you are loading your lens.

Step 2: Open the jaws of the quick-

release clamp wide enough so that the

jaws clear the entire width of the QR

plate attached to the foot of your lens.

Step 3: While supporting your lens,insert

the quick-release plate on your lens into

the jaws of the clamp and tighten the

clamp securely.Make sure the quick-release

plate is seated properly and captive in the

clamp jaws before letting go of the lens.

Balancing Your Lens On The Sevenoak Gimbal Head:

STEP 1: Preparing to Balance:

Loosen the tilt knob of the Sevenoak Gimbal Head SLOWLY-stand

ready to catch the lens or camera body should one end or the

other rapidly tilt down! Adjust the horizontal position of the lens

forward or backwards depending on how the lens tips (see ﬁg-

ures below). SAFETY NOTE: Retighten the clamp after each

adjustment, no matter how small! Use the two safety stop screws

provided with your Wimberley lens plate or replacement foot to

prevent the lens/camera combo from sliding out of the clamp

when loosened.

If the front of the lens tilts downward

you will need to sild the lens backward

in the clamp toward you.

If the front of the lens tilts upward,

you willneed to slide lens forward

away from you.

STEP 2: Balance the Horizontal Position of the Lens:

Use caution when adjusting

the center screw (see page 7).

Mounting SK-GH01to a tripod:

Setting up the Sevenoak Gimbal Head

Assembling the Sevenoak Gimbal Head is a simple matter

of attaching the Head’s platform (detached to make it

more compact for shipping) to the swinging arm of the

Head. Do not tighten the platform knob unless it is mounted

on the Head.

Step 1: Align the platform jaws

properly with the dovetail grooves

in the swing arm. Slide the platform

onto the swing arm of the Head.

Slide the platform all the way

down until it hits the “stop” at the

bottom.

Step 2: Tighten the platform knob

ﬁrmly. (The platform should lock

securely to the arm without the

need to apply extreme torque).

The platform height will be adjusted

later if needed.

Step 1: Firmly tighten the lower (pan) knob.

Step 2: Position the Head with

the spool mounting hole (located

under the spool) directly over the

threaded tripod mounting stud.

It is important to keep the Head

completely straight (vertical) over

the stud to keep the spool threads

from cross - threading.

Step 3: Screw the Head clockwise

onto the stud of your tripod until

it seats the bottom spool of the

Head and the tripod mounting

plate. Use the leverage hole to

achieve a tighter attachment if

desired (see below).Loosen the

pan knob slightly and rotate the

Head to check the security of

the mount. The spool should not

loosen when you turn the Head

counterclockwise, and the Head

should not wobble at all.

Arm

Platform Knob

Platform

Pan Knob

Quick-Release Knob

Never loosen or remove the 3 small

screws on the top of the pan base.

If your tripod has a smaller ¼” mounting stud , check to see

if it is a reversible stud with a 3/8”-16 threaded section on the

other end. If so, reverse the stud and use the 3/8” end of the

stud. If the ¼” stud is not reversible, you will need to use a

reducer bushing to mount the Head to the tripod. Robust

brass bushings can be ordered through our website.

SK-GH01

Gimbal Head

will allow you to properly balance your lens on our gimbal head.

Our plates are also all equipped with safety stops which protect

your gear from accidentally slipping out of a compatible quick-

release clamp.If you use plates from other manufacturers you

will need to make sure that they are the proper length and pro-

portion that we recommend for your lens.Compare the plate

length and proﬁle to the recommended plate for your lens in our

product catalog or on our web site.

loosen and tighten the mechanisms for ﬂuid motion or static

shots. You should avoid unscrewing any of the knobs all the

way, and there should be no need to over-tighten them.

Adjust the position of the lens in small increments until it remains

level when the Head’s tilt knob is loose.

Note: because there is some damping friction in the tilt mechan-

ism, the lens may stay level even when it is slightly unbalanced.

This is okay, but if you wish to ﬁne tune the balance even further,

gently tilt the lens up 20 degrees from level and then down 20

degrees from level. If it’s easier to tilt the lens up, slide the lens

slightly forward. If it’s easier to tilt the lens down, slide the lens

backward. Adjust in this manner until the resistance is symmetric.

Proper Horizontal Balance:

1. Carry a small ball head, attach a quick-release plate to

the bottom of it, and attach the ball head directly to the

clamp on the Wimberley Head. This eliminates the need to

adjust the legs of the tripod to level the horizon or to remove

the Wimberley Head, but it can be inconvenient to have to

carry an extra head with you.

2.Use a small beanbag with the Head; you can set the

beanbag on the top of the Head itself, or on top of your big

lens while it is still attached to the Head.

Other alternatives for attaching the camera body to

the Sevenoak Gimbal Head:

Once you have properly adjusted the forward-backward position

of the lens, you may need to adjust the vertical position of the

lens (especially telephoto lenses smaller than a 600 f/4 or 400

f/2.8).

Loosen the platform wing knob and adjust the vertical position

of the platform so that the center of the lens is slightly above

the tilt axis of the Head (see ﬁgure to the right).

Loosen the tilt knob and tilt the front of the lens about 30 degr-

ees toward the sky. When you let go of the lens, if it wants to

keep going up in the direction that you’ve tilted it, you need to

lower the position of the lens by adjusting the position of the

platform. If the lens wants to return to a level position, you need

to raise the position of the lens.

The goal is to perfectly balance the lens so that it stays pointed in

any position even when the Head is completely loose. Fine tune

the vertical and forward-backward position of the lens until you’

ve achieved perfect balance. Once you have done this a few times,

it gets much easier to do and will take very little time to achieve as

you get more practiced.

TIP: Once you are able to let go of the camera/lens combo in any

position with the tilt and pan knobs loose and it stays in a balanced

position without moving at all, you may want to mark the exact

position of your lens plate within the clamp, and your platform

position on the tilt arm, with a pencil, permanent ink marker or tape

for faster set up in the ﬁeld.

The Head is now ready to use. Simply loosen the pan and tilt knobs

about a quarter turn and start shooting. If you have done everyt-

hing properly, the lens should be very easy to point, should stay

pointed and should not tend to ﬂop or creep. As you become more

familiar with the Head you will probably be better able to make ﬁne

adjustments in the balance of your setup. You can shoot with the

knobs loose, or lock - in on a target by tightening the knobs. You

should not need to loosen the knobs more than a few turns to

unlock the Head. Conversely, there should be no need to over

-tighten the knobs. If things don’t feel right, please contact us.

Knob screws are captive and should not loosen or come o on

their own.

The tilt and pan knobs should tighten with enough friction to keep

the Head from moving on its own. The pan base and swing arm

should not move easily when the knobs are fully tightened.If sig-

niﬁcant force is applied, the Head will slip slightly on the spool

when the panning knob is tightened all the way. THIS IS NORMAL

AND DOES NOT AFFECT PRODUCT PERFORMANCE. When using

the Head, you can put a small amount of friction on both the pan

and tilt to hold the position of your lens and rotate it with a bit of

force as needed. This is not going to going to damage your Head.

Only a single turn or two of the pan and tilt knobs should allow you

STEP 3: Balance the Vertical Position of the Lens:

MAINTENANCE & TROUBLESHOOTING:

A 7/32 hex key ﬁts the 3/8”-16 center

screw on the top of the pan base of

your Sevenoak Gimbal Tripod Head

(see ﬁgure at right). This screw applies

pre-tension to the pan base (so there

is no slop in the mechanism),and adjusts

the minimum drag for the pan base.

You should not have to use this adjustment

on a regular basis. The minimum drag is the amount of

resistance in the pan mechanism when the Head is

un-tightened. We have set the minimum drag for your Head

to a level that we feel is optimal for ﬁeld use. You should not

need to adjust the screw unless you experience an undesirable

change in the Head’s minimum drag as the Head wears in.

CAUTION: Only a very small adjustment should be necessary;

do not remove the screw or back it out excessively. Doing

so could compromise the screw’s ability to lock in place and

the performance of your Head.

Fine Tension Adjustment of Your Pan Base :

Firmly tighten the pan knob, then turn the Head counterclo

ckwise. It should loosen easily from the platform during the

ﬁrst rotation.If the Head has been on the tripod for a while,

more force may be necessary to remove it. If the Head is

stuck, try using the lever age hole for removal (see details at

Removing the Head from your tripod :

the bottom of page 3). The pan base screws do not tighten

the Head to, or loosen it from, the tripod mount.

In extreme situations where it is not feasible to send the head

in for repair, and you wish to attempt to ﬁx a problem yourself,

you do so at your own risk; however, these guidelines will help

improve your odds of success and help you to avoid making the

situation worse. Note: Any ﬁeld repair should be followed up

with a proper repair from us as soon as possible.

Emergency Repairs:

Few things are likely to go wrong with the SK-GH01, and there

should be almost no need for routine maintenance of internal

parts. However, if the Head is in need of repair, we ask that you

return the Head to us for inspection and service. (International

customers should contact the dealer who sold you the Head).

If the Head is faulty, we will ﬁx it free of cost. If the problem

arises from extreme use, abuse or accident, we will repair the

Head for a reasonable fee.

We strongly discourage you from disassembling this unit without

direct instruction from us. Any damage to the head resulting

from disassembly will not be covered by warranty. In special

cases where an emergency repair is required, please refer to

the guidelines to the right.

IF You Have a Problem With Your Head:

Tilt Mechanism:

To disassemble the

tilt mechanism, remove the captivating

screw and unscrew the Tilt Knob. If

you need to remove the grease in

the mechanism, it is okay to use the

tilt mechanism without grease until

you have the opportunity to send it in for us to refurbish.

Pan Mechanism.Remove ONLY the

large central fastener on top of the

Pan base to disassemble the pan

base. DO NOT loosen or remove

the three smaller screws, and do

not attempt to remove the Pan Knob. If you clean the

components of the pan mechanism, you MUST apply oil to all

mating surfaces before reassembling, failure to do so could

cause the mechanism to gall and freeze-up permanently.
