SYSTEM DESCRIPTION

Introduction

The Simrad SH80 sonar is an omnidirectional high frequency sonar, designed for all sized fishing vessels, both purse seiners and trawlers. The standard frequency is 116 kHz (multiple frequencies as option), and the beam can be electronically tilted from +10 to –60 degrees.

Great emphasis has been placed on giving the best possible presentations on a high resolution colour display. The processor unit is controlled by Microsoft’s Windows XP ® operating system, which result in a flexible choice of display modes for a large range of user applications.

The signal processing and beamforming is performed in a fast digital signal processing system using the full dynamic range of the signals. In addition to the traditional single frequency transceiver system, the SH80 sonar contains an advanced frequency modulated filter system (FM).

The cylindrical multi-element transducer allows the omni-directional sonar beam to be tilted electronically down to

-60 degrees. This allows you to automatically track schools of fish, and to observe the whole water volume around the vessel.

A stabilization system is included for electronic pitch and roll compensation.

System overview

Main units

The Simrad SH80 sonar consists of the following units:

• Wheelhouse units:

- Display monitor

- Sonar Operating Panel

- Sonar Processor Unit

- Sonar Interface Unit

• Sonar room units:

- Transceiver Unit

- Hull Unit

Wheelhouse units

The Display Monitor is a high-resolution colour LCD (Liquid

Crystal Display). In addition to the sonar picture, the monitor can also display the user menu for the interactive operation. In order to ease the situation comprehension, certain colours have been chosen to better the distinction between the various elements in the scene.

The Operating Panel contains all necessary control functions for operating the sonar. The controls are arranged in function groups, which gives a clear and easy operation. Note that all sonar operation also may be made from the trackball, or from an optional standard mouse.

The Sonar Processor Unit contains a ruggedized computer, which runs the Microsoft Windows XP ® operating system.

The software has been modified by Simrad to suit the SH80 sonar requirements. The unit holds a CD R/WR unit to be used for future software upgrades.

The Sonar Interface Unit provides interface for all auxiliary equipment; log, gyro, GPS, echo sounder, trawl systems, purse seine systems etc. One signal cable is used for the communication with the Transceiver Unit in the sonar room.

Note that SH80 sonars shipped before August 2003 use a different Sonar Processor Unit; the APC10. These sonars do not have the Sonar Interface Unit fitted. All interfaces to peripheral equipment are then handled by the APC10.

Warning:

System description

Sonar room units

The Transceiver Unit is located in the sonar room, close to the

Hull Unit. One signal cable is used for communication with the

Sonar Interface Unit in the wheelhouse. The transceiver performs the signal processing and the digital beamforming of the 240 transmitters and 480 receiver channels, which are located on the eight identical transceiver boards.

The Hull Unit is designed to be lowered 1.0 meters below the ship’s hull. The transducer can also be lowered to any selectable middle position. Note that in case of voltage failure, the Hull

Unit can be manually raised or lowered by means of a hand crank.

The cylindrical 480-elements transducer allows the sonar beam to give full 360 degrees coverage of the water volume down to

-60 degrees.

The sensor for the electronic stabilization of the sonar beams is housed in the Motor Control Unit, which is mounted on the Hull

Unit.

If the transducer hits larger objects or bottom, the transducer shaft may be bent, or in worst case it can be broken off. A broken transducer shaft will cause water leakage in the top of the shaft. To prevent larger leakages in such a case, do not raise the transducer shaft to the upper position. To prevent serious damages it is therefore of great importance to have a good pump and warning system in the sonar room.

Options

General

The standard SH80 sonar is a single 116 kHz version with beam stabilization.

The beam stabilization was an optional function until 1 January

2003. After that date, the function was included with the standard sonar delivery.

The options described below are pre-programmed into the standard software version, and a code word is required to make the actual option available. Simrad offers a 1 month free test period for certain options. Note that the Scientific Output function is not available for such a test period.

For a permanent installation of a chosen option, a new code word will be released from Simrad when the option is ordered.

Multiple-frequency

In addition to the standard 116 kHz frequency, a multiple frequency option is available. In this multiple frequency version you can select between 13 frequencies from 110 to 122 kHz in 1 kHz steps.

Scientific output

The Scientific Output is designed for research purposes. When activated, the following data are available on an Ethernet (LAN) output:

• Beam data

• Target data

• Own ship data

• Gear data

The scientific output option may also include software for a

Scientific Data Logger.

Note that this option is not available for a free test period.

System description

Functional description

Introduction

The basic principles of the SH80 sonar are unique because of the 240 transmitter and 480 receiver channels with their transducer elements spread around on the cylindrical transducer array.

The transmission, reception and data processing are under computer control, and the powerful capabilities of the sonar are the results of sophisticated digital signal processing software and state of the art hardware.

Functional principles

When the Omni beam is tilted, the total beam picture can be compared with folding an umbrella, which means that all beams in 360 degrees around the vessel have the same tilt angle.

Omni beam principle

850-164385 / Rev.C

The beam can be tilted from +10 up to -60 degrees down.

In addition to seeing the target from above, it is also possible to see the target from the side, by using the vertical slice presentation. In this case the beam covers a continuous vertical beam from 0 to -60 degrees in one transmission.

This vertical slice, which is presented by the white audio line in the horizontal picture, can be selected to any bearing by the manual training control. The combination of the Omni mode and the vertical slice will give an optimal visualization of the catch situation.

7

Simrad SH80

60 degrees vertical slice

Omni/Vertical combination

In addition to the Omni picture, the vertical slice is especially useful for visualizing the vertical distribution of a school of fish.

In that way, it is not necessary to go over the target to see the distribution on the echo sounder, which often results in a spreading of the school.

850-164385 / Rev.C

Stabilization system

System description

Stabilization system

When the beam stabilizer is activated, both horizontal and vertical beams will be stabilized electronically for roll and pitch movements up to ±20 degrees. The beam direction will then change continuously according to the vessel’s movements, and secure an optimal contact with the targets even in rough seas.

850-164385 / Rev.C

Reception

A great effort has been made to reduce unwanted noise to get a clean and stable echo presentation. To achieve this goal the sonar receiver has the following filtering possibilities:

FM Correlation filter

In addition to the traditional single frequency transmitting method, the SH80 sonar is equipped with an FM correlation mode.

In FM mode each transmission pulse contains up to four different frequencies, and the receiver makes a spectrum analysis and compares the received echoes with the transmitted frequency code. This provides a filtering effect, which efficiently reduces interference, noise and reverberation. In addition to giving a clean and stable echo presentation, this will normally also increases the sonar’s detection range

Frequency selection (

O ption)

The optional multiple frequency selection can be used for suppression of interference from other sonars.

9

Simrad SH80

10

However, the sound absorption in salt water increases with the frequency, thus giving the lower frequencies a longer detection range.

RCG (Reverberation Controlled Gain)

The RCG filter senses the noise level (reverberation, propeller noise, etc.), and adjusts the gain individually for each of the 64 receiver beams in order to eliminate noise on the display. The strength of the filter can be selected in the menu. With maximum strenght is selected, the RCG will effectively reduce the bottom in shallow water, while variations on the bottom will be displayed.

Note that scattered fish can be perceived as reverberation. The

RCG filter must therefore be used with care if scattered schools are to be detected.

PP Filter

The SH80 sonar is equipped with a ping-to-ping filter to give a clean and steady presentation by reducing the interference and noise. This filter compares the echoes from a selected amount of transmissions (pings), and an echo has to be present in the selected amount of pings in order to be presented on the display.

Note that in rough seas, when the beam easily can miss the target in several pings, the PP filter must be used with care.

TVG (Time Variable Gain)

The TVG function controls the gain of the receiver so that a school with a given size and density is presented with approximately the same strength on the display, inside the regulated TVG range. This can also be seen as a filter, because it reduces the noise close to the vessel.

The regulated strength of the TVG can be selected in the menu.

Transmission

The transmitting is controlled by the signal processor in the

Transceiver Unit. The parameters you have chosen are used.

There are 240 separate transmitters in the unit distributed on eight transceiver circuit boards. Each transmitter is individually addressed and controlled from the signal processor. The controlled parameters include power output and time delay for each transducer element in order to form a beam with the selected tilt angle.

850-164385 / Rev.C

System description

When the stabilisation system is active, the tilt angle for each beam will automatically be corrected relative to the vessel’s pitch and roll movements.

Simrad SH80

Peripheral equipment

The SH80 sonar requires connection to a speed log and a course gyro. An inaccurate log or gyro input will cause inaccurate indication of the vessel and target movements.

In addition to log and gyro, the following peripheral equipment can be connected to the sonar.

• A (D)GPS may be connected to the SH80 sonar to establish the vessels position and provide cursor and marker latitude and longitude.

• Simrad echo sounders (EQ, ES and EK Series) provides a bottom plot on the catch data page.

• Simrad PI32 and PI44 Catch Monitoring systems provide the net depth in digits and bars on the catch data presentation.

• Simrad trawl instrumentation; FS 900, FS 3300 or ITI

- FS 900 and FS 3300: The trawl will be displayed in correct depth.

- ITI: The trawl will be displayed in correct size, depth, distance and bearing.

• A Current meter system will indicate the current speed and direction for up to three different depths in the sonar picture.

• A radio buoy system (GPS type) will provide the geographical position of the buoy(s) in the sonar picture.

For connection of any of this peripheral equipment, contact your local dealer.

Display mode selection is made on the second menu button in the main menu. The four first display modes shown can also easily be selected with the four Mode buttons on the Sonar

Operating Panel.

Note that the descriptive order of the display modes in this chapter has been chosen only to simplify the descriptions. In operational conditions, the order of the display modes depends on the selected gear (seine net, bottom trawl or pelagic trawl)

This is because different initial display modes are used for easy selection by the four Mode buttons on the Sonar Operating

Panel. The order of these display modes can easily be changed in the Sort Mode menu.

All the display modes in the following chapters are shown without echoes.

Bow Up

When Bow Up mode is selected, the vessel symbol is stationary on the screen with the bow pointing upwards. The echo presentation covers 360 degrees around the vessel, and all echoes are updated for every ping. The distance from the vessel symbol to the outer echo ring is equal to the selected range.

14

The movement of the echoes across the screen are controlled by a combination of the vessel’s course and speed and the target’s own movements.

North Up

When the North Up mode is selected, true north is always up on the screen. The vessel symbol is stationary with the bow pointing in the vessle’s course direction. The movement of the echoes across the screen are controlled by a combination of the vessel’s course and speed and the target’s own movements.

True Motion

When the True Motion mode is selected, the picture is locked to a geographical position, where the vessel moves around the screen according to its present course and speed. All echoes are always presented in their correct position relative to the vessel, and their movements on the screen will be a true representation of the movements of the targets through the water.

16

When the vessel symbol reaches the edge of the screen, it will automatically be moved back to the centre, or to a position determined by the Off Centre button. This position is reset to the screen centre whenever the mode is changed. When you select Target Track, the target will automatically be moved to the screen centre.

Display modes

180°/Audio

When the 180°/Audio mode is selected, the upper half of the screen shows a 180 degrees bow-up presentation, while the lower part is used for a recording of the audio channel.

850-164385 / Rev.C

The audio channel is shown with a continuous white line in the horizontal picture, and it can be trained in any direction. The recorded echoes are a direct replica of the echoes under the white audio line. As the audio channel is recorded over a period of time, this mode is especially useful for detection of weak echoes mixed with reverberation or noise.

The information recorded by the audio channel is always stored in the computer, even if another mode is selected. That means that this recording will always be presented when selecting the

180°/Audio mode. Note that the vessel symbol can be moved to any position in the horizontal view with the cursor and Off

Centre button.

270°/Vertical

The 270°/Vertical mode is specially designed for purse seining.

The vertical half slice is displayed in the lower left corner for normal setting with the net on the starboard side. If the net is set on the port side, the 60 degrees vertical slice will be displayed in the lower right hand corner.

18

With this presentation, it is easy to keep the best contact with a school in both the vertical and horizontal presentation, and to determine its size distribution. The position of the school relative to the bottom is another important information provided by this presentation. The Catch data presentation for purse seining is shown on the right hand side. It shows all the net data relative to the target and the bottom, as well as all available target data.

Dual 1

Display modes

The Dual 1 mode is a kind of “two sonars in one” operation, where each presentation is updated for every second transmission. All settings can be set individually for each of the two presentations. This makes the dual mode especially useful for optimizing settings by directly comparing the two presentations.

850-164385 / Rev.C

To optimize the horizontal settings, use the Horizontal menu to try different settings in the upper picture. These settings are automatically transferred to the other modes.

The dual operation may also be used for other user applications, where different range, tilt, frequency and other parameters can be selected.

Sonar Operating Panel

A thorough understanding of system functions and controls is necessary to optimize overall performance. Sonar conditions vary, sometimes drastically, and it is not possible to identify settings that will provide the best data at all times. Careful study of the information in this manual is highly recommended, preferably while exploring the sonar’s various functions. System operation is a dynamic activity requiring regular adjustments and fine tuning to achieve the best possible results under varying environmental conditions.

850-164385 / Rev.C

Simrad SH80

Main switch

Main switch functions control power to the sonar, hoisting and lowering of the transducer and indicates the transducer’s current position.

Power

Pressing Power for approximately two seconds powers up the sonar. The adjacent green LED blinks while the Sonar Control

Unit boots up, and remains illuminated once the system is operational.

Before the sonar can be powered down, the transducer must be in the Up position. Pressing the Power button for approximately two seconds secures power to the unit which is confirmed by the adjacent green LED being extinguished.

Up

Raises the transducer to its upper position. The adjacent green

LED blinks while the transducer is raised and remains illuminated once it is housed safely inside the hull of the vessel.

The green blinking LED will also be accompanied by an audible signal.

Middle

Raises or lowers the transducer to its middle position.

The physical location of the middle position can be defined in the Transducer parameter dialogue.

Down

Lowers the transducer to its lower position. The adjacent green

LED blinks while the transducer is lowered and remains illuminated when lower position is reached. The green blinking

LED will also be accompanied by an audible signal.

Symbol

The Symbol functions provide on-screen graphic references for targets, own ship and fishing gear.

(A) Target marker

To mark a target, move the cursor over it and press the button. A triangular symbol with a corresponding number will appear on the screen over the target.

Position data for the defined markers are displayed in the Objects menu.

Note that the system continues to track the markers even when outside the sonar range.

The Target marker function can also be used for manual target tracking as the system is designed to calculate the speed (S), course (C) and distance (D) between the last two chosen targets.

The Target marker data is displayed in white figures for three minutes in the lower right hand corner of the horizontal presentation. This function is also an effective method for determining the distance between two selected points on the screen.

(B) Own ship marker

The “own ship” button produces a square symbol on the screen at the vessel’s current location when the button is pressed. The own ship marker’s position data is displayed in the Objects menu.

(C) Circle marker

This marker may be used to estimate the size of a school of fish or as an indication of the size of the purse seine. To activate the function, move the cursor to the desired position and press the button. A circular symbol will appear on the screen at the chosen location. The size of the symbol is equal to that of the purse seine selected.

(D) Gear symbol

The gear symbol may be either a purse seine circle or a trawl symbol depending on the parameter chosen by the Gear button in the Setup menu. The selected gear symbol will be displayed in yellow.

25

Simrad SH80

Seine circle

This is a useful aid in planning the shooting of the purse seine. It is used as follows:

1.

Press the Gear button.

- The purse seine circle will appear on the forward end of the ship symbol on the corresponding side of the vessel selected in the Setup menu. The circle will follow the vessel’s movements.

2.

At the moment the seine is shot, press the Gear button again.

- The purse seine circle will remain stationary and indicate the ideal path for setting the seine. Three square symbols on the ship’s course line indicate the: shooting, one half, and the end of the seine positions.

Three different nets can be pre-programmed in the

Gear menu.

3.

Press the Gear button to delete the Purse Seine circle.

Trawl symbol

Manual tilt

In Manual mode the transducer may be tilted within the systems limits by pressing the Tilt up (arrow) or Tilt down

(arrow) buttons. Pressing either button once changes the tilt angle in steps of 1 degree. Pressing and holding either button continuously changes the tilt angle until pressure is removed.

In the Position and Target Tracking modes, the tilt angle will automatically be adjusted to compensate for the distance to the tracked position.

Auto tilt

In the Auto Tilt mode the selected tilt angle forms the centre of the tilt search. The selected tilt limits are displayed on the tilt indicator by yellow lines and corresponding numerical values for both the upper and lower limits.

The centre of the tilt search sector is adjusted by pressing the Tilt up (arrow) or Tilt down (arrow) buttons. Sector limits are adjusted by pressing and holding the Auto button and simultaneously pressing the Tilt up (arrow) or Tilt down (arrow) buttons.

Tilt search sector limits can be incremented in steps of 1 degree to 10 degrees according to the value selected in the in the Tilt menu.

The Auto Tilt function responds differently with regard to the training mode selected as follows:

• Manual training mode: The transducer automatically changes the tilt angle after each transmission in steps within the selected limits.

• Auto search training mode: The transducer automatically changes the tilt angle after each complete search is performed.

• Position and Target Tracking modes: The tilt angle’s search centre will automatically be adjusted with regard to the distance to the position being tracked. The transducer will tilt automatically in steps after each transmission.

If the stabilization system is activated, the beamformer will automatically adjust the tilt angle with regard to the vessel’s motion (even if manual tilt is selected). The change in the tilt angle for the beamformer will not be shown on the tilt indicator.

About parameter dialogues and help

This chapter describes all the parameter dialogues accessed from the menu system.

When a parameter is selected, the available choices are shown in the dialogue below the menu. The setting is then made using the available buttons or lists. Several levels are frequently used to select the parameters.

Note that:

1.

In many cases you will not need to open the parameter dialogue, as you can control the settings directly on the menu button.

2.

The parameter is selected and activated by the sonar once it is highlighted in the dialogue. The operational changes can thus be investigated from within the dialogue without closing it.

3.

The Close button will always close the dialogue.

4.

The Help button will always provide short-form context sensitive help. This help text will appear on top of the parameter dialogue, and you need to press Close to return.

In the Help window, you can also press Free to access to full interactive manual. This may not be available in all modes, as it will block the view of the sonar echoes.

Once the interactive manual has been accessed, you need to press Free to reduce the large help window back to short-form presentation. If you press Close in the interactive manual, the manual will automatically appear next time you press Help in a parameter dialogue.

The menu settings marked with an asterisk, indicate the normal setting which perform well under normal conditions. If one got lost in the menu settings, a Default Settings function will bring up these normal settings.

After experience, when the contents of the menus are better known, the increase/decrease function on the actual menu button can be used directly without selecting the submenu.

The Beam command enables you to select the vertical beam width in the horizontal presentation. The beam selection can be made manually , or controlled automatically by the selected range.

The Wide beam is designed to be used with shorter ranges in order to obtain a larger vertical coverage. This makes the sonar less “tilt dependent” in the catching phase.

The Normal beam is designed to be used for the medium ranges.

The Narrow beam is provided for the longer ranges. The focused narrow beam has the highest source level, which increases the detection range.

86

(A) = Wide (B) = Normal (C) = Narrow

In the Auto mode, the beam will change automatically defined by the range selections made by the Wide and Normal buttons.

850-164385 / Rev.C

Colour Threshold

The Colour Threshold button is located on the Display menu.

The Colour Threshold function is used to reduce the number of echo colours on the display.

The strength of the echoes is indicated with a scale of 16 or 64 colours. A weak echo has a cold colour (blue), medium echoes have warmer colours (green, yellow) and strong echoes are shown with the warmest colours (orange, red). If desired, the number of colours may be reduced. When you do this, the sonar witll start with the colour indicating the weakest echoes.

Therefore, by reducing colours, the maximum detection range will be reduced, because all echoes will normally appear as weak echoes at long ranges.

92

850-164385 / Rev.C

850-164385 / Rev.C

Colours

The Colours button is located in the Display menu.

Parameters

The colour strength of the echo presentation can be selected with three different colour scales. Under normal conditions, the

CW (Continuous Wave)

The frequency of the transmitter pulse is here constant, equal to the selected frequency (if the optional multiple frequencies are installed).

There is a selection between three different pulse lengths:

Short, Normal and Long. In addition the pulse length will change automatically in accordance with the selected range. The table shows the different pulse lengths given in milliseconds

(ms).

Auto

In Auto mode, the transmitter pulse is made with a combination of FM and CW to give an optimal echo presentation for all ranges. This combination is designed from operational experience, and will change automatically between FM Long in the shorter ranges, and CW Long in the longer ranges. The table shows the mode and pulse lengths (ms) which are used for the different ranges.

FM (Frequency Modulation)

In the FM mode, the transmitter pulse is frequency modulated.

This provides a stable echo presentation and greater ability of detection as noise and reverberation are reduced.

There is a selection between these different FM modes:

• FM Short - Transmits one-frequency pulse with a total pulse length of 3.2 ms for all ranges.

• FM Normal - Transmits one-frequency pulses with a total pulse length of 6.4 ms up to the ranges of 150 meters, and two-frequency pulses with a total pulse length of 12.8 ms for the longer ranges.

• FM Long - Transmits one-frequency pulses with a total pulse length of 6.4 ms up to the ranges of 300 meters, and four-frequency pulses with a total pulse length of 25.6 ms for the longer ranges.

The selected number of frequencies are transmitted in one ping, and the receiver undertakes a spectrum analysis to compare the received echoes with the transmitter’s frequency code. This provides a filtering effect, where only “own echoes” are displayed, and noise and other echoes are reduced. The table on the previous page shows the maximum FM mode for all ranges.

Warning:

Docking the vessel

When docking the vessel, great care must be taken not to damage the sonar trunk and protecting blister.

The sonar must never be powered up when the ship is in dry dock. The transducer will be damaged if it transmits in open air. To prevent inadvertent use of the sonar, disconnect the mains plug on the Sonar Processor Unit whenever the vessel is in dry dock.

The location of S302 in the Motor Control Unit

158

850-164385 / Rev.C


On vessels which have been in dock, the Hull Unit must be thoroughly examined, and the hoist/lower functions must be checked out and observed while operating the Hoist/Lower

Switch (S302 in the Motor Control Unit). The hoist/lower motor will automatically stop when the transducer shaft reaches the upper or lower limit switch.

Remember to set the hoisting/lowering switch back to Remote for normal operation.

850-164385 / Rev.C

159

Simrad SH80

Note:

Cleaning the transducer

The transducer normally needs little attention. However, the transducer face should be inspected and cleaned whenever the vessel is in dock.

To lower the transducer when in dock, use the hoist/lower switch S302 in the Motor Control Unit (mounted on the gantry).

Set the switch to STOP to position the transducer at any vertical location.

Do not use strong solvents, but a normal synthetic soap and water. Marine growth must be carefully removed with fine-grade sandpaper or emery paper.

The transducer surface must not be painted.

850-164385 / Rev.C


The location of S301 in the Motor Control Unit

Hoist motor overload protection

To prevent the hoist/lower motor from overload, an overload circuit breaker S301 is located in the Motor Control Unit. This may automatically be switched off during hoisting if the vessel’s speed is too high, or if the transducer shaft has been bent.

To reset the motor overload switch, open the Motor Control

Unit, locate the switch S301 and press the button marked 1.

850-164385 / Rev.C

161

Simrad SH80

Warning:

162

Emergency hoisting and lowering

In case of a failure or an emergency in the normal hoist/lower operation controlled from the Sonar Operating Panel, the transducer may be hoisted and lowered from the Sonar Room.

Local control switch S302

If the 3-phase voltage for the hoist/lower motor and the +24 Vdc stand-by voltage from the Transceiver Unit are available, the transducer can be hoisted or lowered by means of switch S302 in the Motor Control Unit. The motor will automatically stop when the transducer shaft reaches the upper or lower limit switch.

Remember to set the switch back to Remote position when finished.

Hoist/lower contactors K301 and K302

If the 3-phase voltage for the hoist/lower motor is available, the transducer can be hoisted and lowered by operating the hoist

(K301) and lower (K302) contactors in the Motor Control Unit by activating the small switch handle on the front of the contactor.

The switches must be released before the transducer shaft reaches upper or lower position, as this operation overrides the two limit switches.

Manual hoist and lower operation

If the 3-phase voltage is not available, the transducer must be hoisted and lowered by means of the hand crank. Observe the following procedure.

1.

Locate the motor overload switch S301 in the Motor

Control Unit, and press the red button marked 0.

2.

Locate the hand crank in the Motor Control Unit.

3.

Remove the plastic plug on the top cover of the Hull Unit, and mount the hand crank onto the stub shaft through the hole in the top cover.

4.

Use the hand crank to hoist and lower the transducer.

5.

Remove the hand crank from the stub shaft, and mount it in its storage position in the Motor Control Unit.

6.

Press the black button marked 1 on the motor overload switch S301.

Lubrication of the Hull Unit

From the factory, the Hull Unit is lubricated with the types of oil or grease as specified below. However, if of equal quality, other types may be used. The following number refer to the lubrication points on the illustration to the left.

(1) The ball bearing on the top of the hoist/lower screw must be lubricated with normal ball bearing grease.

(2) The hoisting spindle should be lubricated with

Tonna Slideway Oils S68.

(3) Topping up the shaft sleeve through the grease nipple is only required if the shaft is dry of lubrication, or if water tends to force its way up along the shaft. The shaft sleeve is filled with Esso

Cazar K1.

Warning: When you top up the shaft sleeve with oil, you must open the pressure release plug to avoid damage to the shaft bearings.
