draw out the chain. Regulate the chain speed by
gradually engaging/disengaging the band brake.

When the required amount of chain is out, tighten
the band brake and engage the chain stopper.

If the band brake is not fitted, the speed of chain
can be controlled by the clutch. In that case, after
disengaging the chain stopper, slowly release the
clutch by inserting the lever into the clutch nut
and turning it anticlockwise. Regulate the chain
speed by gradually engaging/disengaging the
clutch.

To apply more torque when engaging the band
brake, the brake is equipped with a bar, which
can be inserted into the brake handle as a lever
(Picture 3.3). The bar is normally stored inside the
handle.

3.5 RETRIEVING THE ANCHOR UNDER MANUAL CONTROL
The windlass (models without band brake only) is
equipped with a cranking mechanism to retrieve the
anchor in case of emergency. It involves operating
the windlass manually under heavy load and extra
care must be exercised when using it to avoid injury.
To use proceed as follows:

Check that the chain stopper is engaged. If a
chain stopper is not fitted, ensure that the pawl
(28) is engaged with the chainwheel (11).

Insert the clutch nut lever in the clutch nut and
release clutch by turning the clutch nut in
anticlockwise direction.

Insert the clutch nut lever (the end with spigot)
into the emergency crank collar (15) and engage
the spigot with one of the dogs in the chainwheel
in the furthermost forward position (Picture 3.4).

Pull the lever back as far as possible, bringing the
chain in. Engage the pawl (28) and ease off the
lever.

Push lever to furthermost forward position and re-
engage with the chainwheel.

Repeat the cycle until the anchor is retrieved. It is
a very slow process and should be used only in
emergencies.

!
The chain slack between the tensioner and the
windlass should be kept to less than the end travel
of the tensioner. This allows for safe
disengagement of the tensioner and transfer of
load to the chainwheel.

3.6 OPERATING THE WARPING DRUM INDEPENDENTLY
This is applicable to VW and VWC models only. The
drum can be operated independently of the
chainwheel and can be used to manage docking
lines or a second anchor. To use in this way,
proceed as follows:

Engage the chain stopper, the pawl or the
band brake (whichever is fitted).

Fully disengage the clutch as described in
Section 3.4.
The drum may now be operated independently of the
chainwheel. Maxwell recommends all warping
operations be controlled by the footswitch. This
makes it a one-person operation and offers better
!
While handling docking lines with the capstan,
ensure everyone stays well clear of the lines and
the capstan.
