Safety

Always follow the instructions that accompany a Caution. The information it provides is intended to minimize the risk of personal injury and/or damage to property. In particular, observe safety instructions that are presented in the following format:

CAUTION — This alert warns of a hazard or unsafe practice which, if not avoided, can cause injury or damage.

Note — An absence of specific alerts does not mean that there are no safety risks involved.

Care of the system

To maximize the life expectancy of the foam drive wheel, as soon as you finish using the system, hinge the electric motor until it locks in the "away" position.

When you are not going to use the EZ-Steer system for a long period of time, remove the EZ-Steer motor from the vehicle and store it in a dry location to prevent damage from condensation and other moisture.

Highway usage

You must remove the motor assembly from the mounting bracket prior to driving the vehicle on a public highway. To remove the motor, undo the two thumb screws.

Cautions

CAUTION — This manual relates to the EZ-Steer system when used with the EZ-Guide Plus system. It should not be used with the EZ-Guide 500 system. If your EZ-Steer system is connected to an EZ-Guide 500 system, refer to the EZ-Steer System for the EZ-Guide 500

Lightbar Reference Guide.

CAUTION — For continued protection against the risk of fire, replace the cigarette lighter fuse only with same type and rating of fuse. Fuse: 8A, 250V, 3AG type.

CAUTION — Always hold the steering wheel while you adjust the column tilt. Otherwise, the weight of the motor may cause the steering wheel to drop suddenly and cause damage to the steering column or dash.

EZ-Steer System Reference Guide Safety 5

CAUTION — Articulated tractors pivot in the middle. Avoid putting yourself in a position where you could be injured by the pivoting rear section of the vehicle.

CAUTION — Do not attach the controller to a vehicle side wall or window because vibration in these locations can cause the controller to output false terrain compensation readings that could affect performance and cause the vehicle to swerve offline.

CAUTION — Mount the controller as solidly as possible using the supplied mounting plate.

If the controller is able to move, or if objects bump it, the controller may make false terrain compensation readings that could affect performance and cause the vehicle to swerve offline.

CAUTION — The EZ-Steer system is not designed to be mounted on machines with an open operator's station (no enclosed operator's cab). Doing so will void the warranty of the EZ-Steer system components.

CAUTION — Ensure that you mount the antenna so that it is level. If the antenna is not level, GPS performance may be reduced.

CAUTION — For optimum performance, ensure that the AgGPS 252 receiver has firmware version 3.0 or later.

CAUTION — Make changes to the system settings in incremental steps. Random changes are likely to result in poor performance.

CAUTION — If you increase the value in the Diseng. Offln. field, the vehicle may overshoot the corners by at least a few feet.

CAUTION — Ensure that the antenna offset measurement is accurate to within 7.6 cm

(3 inches). An incorrect offset can cause the vehicle to swerve offline or oscillate back and forward and may cause damage to the vehicle or other property.

CAUTION — Do not supply voltages greater than 16 VDC to the EZ-Steer system, or you risk permanently damaging it.

EZ-Steer System Reference Guide

Introduction

The EZ-Steer® assisted steering system steers the vehicle down field passes using

GPS guidance from the EZ-Guide® Plus lightbar guidance system, a controller, and a motor mounted to the steering column of the vehicle.

Lightbar Reference Guide.

An EZ-Steer controller with T2™ terrain compensation contains sensors that detect the angle and speed of changes to correct the following errors:

Terrain compensation can significantly improve accuracy on slopes, large bumps, and ditches, and can make steering much smoother.

The EZ-Steer system is designed to provide better performance than a human driver. For sub-inch accuracy for spreading, spraying, cultivation, and broadacre planting, use the AgGPS® Autopilot™ automated steering system.

Getting started

Follow the process below to get started with the EZ-Steer system.

Perform a pre-installation vehicle inspection — see Chapter 2.

Install the system — see Chapter 3.

Set up the system — see Chapter 4.

Calibrate the system — see Chapter 5.

14 Introduction EZ-Steer System Reference Guide

Pre-Installation Vehicle Inspection

Before you install the EZ-Steer assisted steering system, inspect the vehicle.

Note — The EZ-Steer system can use AgGPS Freeplay™ technology to compensate for freeplay (also called “slack”) in the steering hydraulics and linkages. However, the

Freeplay technology cannot counteract mechanical problems or problems caused by the vehicle setup.

This chapter describes some examples of what to look for before you install the

EZ-Steer system on a vehicle.

Photo Problem Cause/solution

Worn components

Worn paint around linkage connection points

The bolt has been loose in the connecting arm hole; this indicates a bad ball joint.

Replace the ball joint.

Worn ball joints

Torn rubber boot seal around ball joint from poor lubrication

The rubber boot seal is missing.

Exposure to water and dirt increases the likelihood of a worn ball joint. To check if the ball joint is loose, turn the steering wheel in short, quick motions left and right.

Note — If your tractor has had a front loader attached, it will almost always have worn ball joints. Replace the ball joints.

To check if the ball joint is loose, turn the steering wheel in short, quick motions left and right.

Check the inner and outer tie rod ball joints for problems.

If the ball joint moves a small distance before the connecting arm turns, replace the ball joint.

EZ-Steer System Reference Guide Pre-Installation Vehicle Inspection 15

Problem Cause/solution

Worn splines In some 2WD tractors, the connecting arm is bolted onto a splined wheel hub shaft. Turn the steering wheel with short, quick motions left and right. The connecting arm should move immediately with the wheel.

If you notice a small amount of connecting arm movement before the wheel turns, it is likely that the splines are worn.

Replace the front wheel hub shaft.

Worn front axle pivot pin bushing

On MFWD tractors with a rigid front axle, turn the steering wheel and watch the front wheels turn.

If the axle moves forward or backward as you turn the steering wheel (see the white arrows), replace the axle pivot pin bushing.

Photo

Worn steering cylinder pins and bushings

On articulated 4WD tractors, turn the steering wheel and check for play in the steering cylinder pins.

If you can see either of the cylinder rods move slightly before the tractor starts to hinge left or right, you must replace the pins and bushings.

CAUTION — Articulated tractors pivot in the middle. Avoid putting yourself in a position where you could be injured by the pivoting rear section of the vehicle.

16 Pre-Installation Vehicle Inspection EZ-Steer System Reference Guide

Problem Cause/solution

Worn steering shaft causes loose steering wheel

A steering column with play in all directions (see white arrows) can cause the steering shaft to bind against its housing when the pressure of the EZ-Steer motor is applied, making it difficult for the

EZ-Steer motor to turn the wheel.

Repair or replace the steering shaft.

Photo

Wheel problems

Uneven tire pressure

Telescope lock does not hold column in place

Tires mounted on the same axle must be inflated to the same pressure. This improves machine stability by preventing cab roll, and reduces the effort required to turn the front wheels.

If the tractor front tires are filled with a fluid such as calcium chloride, slightly increase the

Aggressiveness setting in the

EZ-Steer system.

For some tractors, you may need to clamp a bracket directly onto a telescoping steering column.

Ensure the steering column telescope lock/unlock knob is working correctly. If the steering column cannot be set in a fixed position, the column could telescope freely inward, causing the bracket to strike the instrument panel.

EZ-Steer System Reference Guide Pre-Installation Vehicle Inspection 17

Problem

Steering wheel is loose on steering shaft

Cause/solution

A steering wheel with vertical

“play” (see white arrow) does not provide good contact with the

EZ-Steer system drive wheel.

The drive wheel could slip on the steering wheel outer ring, causing a loss in steering accuracy.

Tighten the steering wheel.

Photo

Front steering is out of alignment

If one or both of the front wheels are out of alignment, the steering will pull to one side and the machine will constantly steer to the left or right and will have problems following a straight or curved line.

Fix the machine's front wheel alignment before installing and calibrating the EZ-Steer system.

Steering wheel is dirty

Grease, oil, or protectants such as

Armor All may cause the foam drive wheel to slip on the steering wheel.

Use denatured alcohol to clean the steering wheel.

Electrical problems

No power from accessory socket

Plug in the EZ-Steer power cable and flip the switch on the male power adaptor. If the accessory socket has power, the green light on the switch is lit.

18 Pre-Installation Vehicle Inspection EZ-Steer System Reference Guide

Problem Cause/solution

If the accessory socket does not have power, check:

• that the accessory socket is connected

• if an in-line fuse has been added and/or if the fuse is blown

Photo

Fuse is too small for power accessory socket

The fuse must be 10 amp or larger. Replace with a larger fuse if necessary.

EZ-Steer System Reference Guide Pre-Installation Vehicle Inspection 19

Problem

Hydraulic fluid

Low hydraulic fluid level

Cause/solution

A low level of hydraulic fluid, or old fluid, can cause the steering wheel to turn the front wheels very erratically, or not at all.

Use a dipstick or sight gauge to check the fluid level.

Top up or replace the hydraulic fluid as necessary.

Photo

Cold hydraulic fluid

If the hydraulic oil temperature is lower than

40 °C (100 °F), the machine’s steering may be stiff, causing the EZ-Steer system to automatically disengage or respond slowly to steering wheel movements.

Before using the system, wait for the hydraulic oil to reach the recommended operating temperature.

High clearance sprayers are prone to having slow steering response until the hydraulic fluid temperature is 66 °C –

82 °C (150 °F–180 °F).

20 Pre-Installation Vehicle Inspection EZ-Steer System Reference Guide

Installation

This chapter provides instructions and tips for installing the EZ-Steer assisted steering system on a vehicle.

Installation process

Install the EZ-Steer motor using the platform kit.

Install the controller.

Check the GPS antenna location.

Note — If you are upgrading from the EZ-Guide Plus system, you may need to shift the location of the antenna on the vehicle to ensure best steering performance.

Install optional switches

Connect the components together

STEP 1: Installing the motor with the platform kit

To install the EZ-Steer platform kit and motor on the steering column of a vehicle, follow the instructions provided with the platform kit.

Also, check for vehicle-specific installation notes at www.EZ-Steer.com.

Check that the EZ-Steer system motor is mounted at an appropriate distance from the steering wheel. The foam wheel should be 3.2 cm (1¼ inches) from the steering wheel when the motor is locked away.

Lock the motor drive wheel away from the steering wheel when the system is not in use. This prevents the foam wheel from developing a flat spot.

Note — If the foam wheel develops a flat spot, you can still use the motor drive wheel. The flat spot does not affect the drive wheel, and will eventually disappear.

EZ-Steer System Reference Guide Installation 21

STEP 2: Installing the controller

Install the controller in a way that prevents dust and moisture from entering it.

Controller mounting locations

Install the controller in the vehicle cab, parallel to the vehicle’s center line and in one of the following locations:

Floor mount

Parallel to the center line of the vehicle, white sticker facing upwards

Vertical mount

Perpendicular to the floor and parallel to the rear axle, with the connectors pointing down toward the floor, white sticker facing towards the front of the vehicle

Connectors facing forward

(preferred for controllers with

T2 technology)

Connectors facing backward

Take extra care not to stand on, kick, or otherwise damage the controller.

22 Installation EZ-Steer System Reference Guide

Controller mounting

If you mount the controller on the floor, look for any cab wiring routed under the floormat before screwing the controller into place.

Use screws that are size #12 or #14, and between ½" and 1" long.

CAUTION — Mount the controller as solidly as possible, using the supplied mounting plate. If objects bump the controller, or if the controller vibrates, false terrain compensation readings are created that could affect performance and cause the vehicle to swerve offline.

Note — If the controller does not have T2 technology (terrain compensation), the controller does not need to be aligned with the center line of the vehicle. However, all other mounting instructions should be followed.

EZ-Steer System Reference Guide Installation 23

STEP 3: Checking the antenna location

For optimal performance, mount the antenna as far as possible from the vehicle

antenna offset reference point (see page 39) but with a clear view of the sky. The

antenna should not be blocked from receiving GPS satellites by, for example, the cab.

Antenna mounting locations for each vehicle type are shown below.

Note — Do not mount the antenna on the nose of the vehicle if you are using

OmniSTAR HP or XP corrections.

CAUTION — Ensure that you mount the antenna so that it is level. If the antenna is not level, GPS performance may be reduced.

Hints for engaging

The following hints should ensure the best performance of the EZ-Steer system.

Engaging angle and distance

If you are a new user, the best practice is to engage parallel to the line.

Use the red/green LEDs to ensure that the vehicle is within 0.6 m (2 feet) of the swath.

Use the lightbar graphics display to turn the vehicle parallel to the swath.

When you are at the operational speed, engage the EZ-Steer system.

Good Poor

Optimum engage distance Engage too far from the line – slow to get online

EZ-Steer System Reference Guide Using the EZ-Steer System 53

Engaging far from the line

Experienced users can engage over 1.5 m (5 feet) from the swath. Ensure that you approach at a shallow angle to get online quickly without overshooting the swath.

Good Poor

Optimum engage angle Engage angle too steep – overshoot

Disengaging

The EZ-Steer system automatically disengages when:

•

the vehicle is outside the limits configured in the Engage Options screen

•

paused

•

GPS positions are lost

If Warnings / Low Accuracy Warning is set to High Accuracy Only, the system disengages if it receives low accuracy positions (for example, no corrections).

To manually disengage the system, do one of the following:

•

Select

on the main map screen and then press o

•

Turn the steering wheel to override the electric motor.

•

Press

on the optional remote control.

•

Depress the optional foot pedal.

When the system is disengaged, three LEDs at each end of the lightbar flash and the optional remote control emits an audible warning.

When the system will not be use for an extended period of time, use the motor lock pin to tilt the motor away from the steering wheel.

54 Using the EZ-Steer System EZ-Steer System Reference Guide

Audible warning

If you have the EZ-Guide Plus system remote control keypad connected to the lightbar, or the Sonalert alarm connected to the EZ-Steer system controller through the optional accessory cable, an audible warning sounds when:

•

you disengage the EZ-Steer system

•

low accuracy GPS occurs

•

a headland or offline warning limit is reached (if this mode is enabled)

Note — For safety reasons, turning the Audible warning option off does not disable the audible disengage warning.

Curve autosteering accuracy

To obtain smoother steering when operating on curves, try setting the Aggressiveness lower than the optimal Aggressiveness setting for straight lines.

Aggressiveness set correctly Aggressiveness too high

EZ-Steer System Reference Guide Using the EZ-Steer System 55

Headlands

It is possible to engage the EZ-Steer system on headlands which have sharp corners at the edge of the field. However, the EZ-Steer system may be unable to drive around these sharp bends. Use one of the following methods to compensate:

•

Manually steer the vehicle around the corner. Once you have rounded the corner, re-engage the EZ-Steer system.

•

Select EZ-Steer / Engage Options and increase the Diseng. Offln. distance.

CAUTION — If you increase the value in the Diseng. Offln. field, the vehicle may overshoot the corners by at least a few feet.

Vehicle-specific performance hints

2WD tractor

•

You can install the EZ-Steer system on tractors that have SuperSteer (for example, New Holland TG). If the tractor has a SuperSteer front axle, for best performance:

•

Use low or medium aggressiveness (100–110%).

•

Line up close to the swath and make certain the front wheels are straight before engaging the EZ-Steer system.

•

To get smoother performance when the vehicle is pulling an implement over tilled ground, enable Diff-Lock. The setting locks the drive wheels together and causes them to turn at the same rate. This prevents the machine from pulling sharply to the left or right.

Note — Turn off Diff-Lock if you are calibrating on a hard surface.

4WD tractor

•

Because the steering on a 4WD articulated tractor is slow, you may need to increase the Freeplay and Aggressiveness settings when traveling at high speeds.

•

The EZ-Steer system can be installed on Case IH STX tractors with Accusteer. For optimal performance, disable Accusteer via the switch in the cab if possible.

Tracked tractor

For best performance, use the following settings when configuring the EZ-Steer system for use with a tracked tractor:

56 Using the EZ-Steer System EZ-Steer System Reference Guide

•

Perform Steps 5–7 of the EZ-Calibration sequence at the speed at which the machine will be most commonly used.

•

If you do not have T2 technology, set Min speed to a value above 4.8 kph

(3 mph). At speeds below 4.8 kph (3 mph), the accuracy of the EZ-Steer system without T2 technology on tracked vehicles drops off quickly.

Sprayer

•

It is common for these vehicles to have slow steering. To compensate for this, set the Motor Speed to Man Max and use high aggressiveness.

•

If the vehicle is slow to get online, or you experience large, slow oscillations, increase the Aggressiveness value.

•

If you are using the T2 technology option, and traveling faster than 24.1 kph

(15 mph) over a rough surface, from Terrain Comp. / Filter select the Roll only option.

Problem Possible cause Solution

The EZ-Steer system is hard to disengage when I manually turn the steering wheel

The Override Sensitivity setting is too low.

Select EZ-Steer / Engage Options and then increase the O’ride Sensitivity setting.

Increase the setting in 5% increments.

Disengage by turning the steering wheel after each change to test its effect.

The EZ-Steer system disengages on large bumps

The Override Sensitivity setting is too high.

Select EZ-Steer / Engage Options and then decrease the O’ride Sensitivity. Decrease the setting in 5% increments. Disengage after each change to test its effect.

The offline distance is too small to accommodate disturbances caused by rough field conditions.

Select EZ-Steer / Engage Options and then increase the Diseng. Offln. setting.

It is difficult to engage the EZ-Steer system

The Maximum Angle setting is too narrow, making it difficult to line up the vehicle within the engage angle.

Select EZ-Steer / Engage Options and then increase the Max Angle setting.

The Engage Offln. limit is too low which means that the vehicle has to be very close to the line before engaging.

Select EZ-Steer / Engage Options and then increase the Engage Offln. limit.

The remote engage foot pedal does not work

Holding the switch shorter than 0.5 seconds will not engage the system.

Hold the switch down for at least

0.5 seconds. Release the switch between

0.5 and 3.0 seconds. The vehicle will engage when the switch is released.

58 Troubleshooting EZ-Steer System Reference Guide

Problem Possible cause Solution

The guidance LEDs jump from side to side and the map is jerky

The Look Ahead setting is too high.

Select Guidance / Look Ahead and then increase the Look Ahead time to 0. This setting does not affect EZ-Steer system performance.

The foam motor drive wheel vibrates

The motor wheel has a flat spot because it was not locked away from the steering wheel when the vehicle was not in use.

When the system is not in use, hinge the

EZ-Steer motor until it locks in the "away" position. The flat spot usually disappears after an hour of operation.

The foam wheel slips on the steering wheel

Grease, oil, or protectants such as

Armor All may cause the foam drive wheel to slip on the steering wheel.

Clean the steering wheel with denatured alcohol to remove grease, oils, and protectants.

There is not enough pressure between the drive wheel and the steering wheel.

Loosen the thumb screws and move the motor closer to the steering wheel. This increases the pressure and stops slippage.

The EZ-Steer motor struggles to turn the steering wheel of the vehicle

An excessively worn steering column is binding in its housing inside the steering shaft when the EZ-Steer motor presses against it.

Repair or replace the steering shaft.

The EZ-Steer motor repeatedly disengages immediately after I engage the system

The steering hydraulic temperature is low, and the steering of the vehicle is very stiff and hard to turn.

Decrease the steering override by 5% increments to 20% or less. Engage the

EZ-Steer system to see if the problem stops.

General GPS

Problem Possible cause Solution

On-the-ground pass to pass errors are greater than 0.3 m

(12 inches)

The GPS position is drifting by more than 0.3 m (12 inches) over two passes.

Increase the AgGPS OnPath™ advanced filter technology decay time from GPS / Filter.

– If there are no trees near your field, select 999 minutes.

– If there are trees nearby, select

30 minutes.

Note — The receiver specification shows accuracy should be 15 cm–30 cm

(6 inches–12 inches) 95% of the time in the American Midwest. If you are not using GPS corrections, the accuracy specification is 15–46 cm (6 inches–

18 inches) in open fields with a decay time setting of greater than 30 minutes.

The GPS antenna is on the nose of the vehicle, which is causing GPS signal blockage.

Increase the Min SNR setting from GPS/GPS

Limits.

Tip: Raise the Min SNR value to 42. If this does not fix the issue, set the Min SNR value to 45.

Note — Altering this setting may affect the overall number of satellites you are able to track. If you do not get a GPS position, drop the setting back to its default value of 40.

The antenna is not level, which may cause GPS signal errors in some directions.

Move the GPS antenna to the top front edge of the vehicle cab, away from other transmitting antennas. Reset the antenna height, axle/antenna offset, angle/turn, and aggressiveness.

Ensure that the antenna is mounted within

5 degrees of horizontal.

The GPS position jumps up to several feet soon after startup

For optimal accuracy with WAAS corrections, the WAAS ionosphere model must be downloaded to the receiver, which can take up to

10 minutes. When the download is complete, the GPS position is updated, which can lead to a position jump of up to several feet.

Wait for 10 minutes after getting your first

DGPS position before you start to use guidance or autosteering.

60 Troubleshooting EZ-Steer System Reference Guide

Problem Possible cause Solution

Intermittent GPS or

WAAS signals – the receiver intermittently loses WAAS correction or GPS positions or only ever tracks seven satellites or less

The vehicle cab, exhaust stack, or bucket loader frame arms are blocking part of the view of the sky from the GPS antenna.

Mount the antenna at least 0.9 m (3 feet) away from any obstruction or source of potential interference. Remove any obstacle that may be blocking GPS signals from near the antenna height, axle/antenna offset, angle/turn, and aggressiveness.

Note — If you move the antenna, recalibrate the EZ-Steer system.

When I use electrical devices in the cab, the

EZ-Guide Plus system loses satellites

Some electrical devices interfere with

GPS signals. If a device emits interference, GPS signals may be jammed. Certain types of two-way radio, DVD players, and some transmitting devices can cause this problem.

If you permanently lose all satellites or only ever get zero or one satellites on a regular basis, switch off all electrical devices in the cab one by one until you isolate the device that causes the issue. If this does not work, move the antenna to the nose of the vehicle to avoid interference.

Note — If you move the antenna, recalibrate the EZ-Steer system.

The vehicle moves offline when I drive past trees

Trees obstruct GPS signals. If a tree is partially blocking a satellite, the

GPS position may shift.

Autonomous GPS

Increase the Min SNR setting (select GPS /

GPS Limits).

Tip: Raise the Min SNR value to 42. If this does not fix the issue, set the Min SNR value to 45.

Note — Altering this setting may affect the overall number of satellites you are able to track. If you do not get a GPS position, drop the setting back to its default value of 40.

OmniSTAR XP/HP

Decrease the Min SNR setting (select GPS /

GPS Limits).

Tip: Lower the Min SNR value to 38.

Note — Altering this setting may affect the overall number of satellites you are able to track. If you do not get a GPS position, increase the setting back to its default value of 40.

To ensure that your EZ-Steer system continues to operate correctly, follow this maintenance schedule during your vehicle’s regular service or at intervals not exceeding three months:

Check that the bolts and nuts that attach the bracket to the steering column are tightened according to the specifications in the steering kit installation instructions.

Inspect the vehicle steering column for signs of damage or wear, paying special attention to the areas around the EZ-Steer bracket.

Check the position of the EZ-Steer motor relative to the steering wheel and, if necessary, adjust it according to the specifications in the steering kit installation instructions.

Check the amount of play in the EZ-Steer motor bearings by gently attempting to move the output shaft from side to side, as well as up and down.

Rotate the motor shaft to check there is no noise or resistance in the bearings.

Check that the motor mount spring applies sufficient pressure to prevent the foam wheel from slipping on the steering wheel. Replace the spring if necessary.

Inspect all cables for damage and replace them if necessary.

Check the foam wheel is secure and not excessively worn.

Remove the plastic plug from the end of the foam wheel. b.

Make sure that the two screws that hold the wheel to the output shaft are tight.

Inspect the foam wheel. If the foam wheel shows signs of excessive wear, flat spots, or deep grooves, replace it.

Reinstall the plastic plug in the end of the foam wheel.

Ensure that the:

•

EZ-Steer controller is securely fastened to its mounting point

•

EZ-Steer controller does not show any signs of physical damage

•

EZ-Steer cables are firmly attached

EZ-Steer System Reference Guide Maintenance 71

Pivot bearing maintenance

The pivot bearing is lubricated at the factory and should not require maintenance.

However, if the steering motor becomes difficult to move from the unlatched to latched position or if there appears to be excessive play in the pivot bearing, follow this procedure to inspect, lubricate, or replace the pivot bearing as necessary:

Ensure that the unit is in its unlatched position.

Remove the motor mount assembly from the steering column bracket.

Remove the shroud: a.

With a sharp hobby knife or razor blade, slit the

“EZ-Steer” label on the front of the motor down the middle where the two shroud halves join.

With a sharp hobby knife or razor blade, slit the part number / serial number label on the angled surface on the rear of the unit.

Note — You do not need to cut the orange warning label.

Remove the four screws that hold the shroud to the upper mount.

72 Maintenance EZ-Steer System Reference Guide

Open the shroud by bending the orange warning label.

Remove the shroud.

A ¼" screw at the center of the shaft holds the upper mount assembly to the lower mount. Loosen the screw until the screw is almost completely removed.

Push the screw head until the shaft and upper mount assembly start to come away from the lower mount.

(There will be some resistance due to the spring force.)

Push the upper mount assembly away until the screw prevents it coming all the way out. The face of the bearing and some of the shaft will now be visible between the upper and lower mounts.

Apply some molybdenum sulphide grease or black grease to the exposed shaft and bearing face.

Push the two halves back together and pull them apart again. Do this several times, to spread the grease.

Tighten the ¼" screw to 5.6 Nm–6.7 Nm (50 in/lb–

60 in/lb).

Hinge the motor until it latches a few times to spread the grease around the bearing.

10. Ensure that the two grub screws on the steering motor output shaft are tightened to 2.8 Nm–3.4 Nm

(25 in/lb–30 in/lb).

EZ-Steer System Reference Guide Maintenance 73

11. Re-attach the shroud: a.

Ensure that the tongue and groove joint is correctly mated.

Tighten the four shroud screws to 2.6 Nm–3.0 Nm (23 in/lb–27 in/lb).

Note — Do not over-tighten the shroud screws or you may damage the plastic shroud.

12. Re-attach the motor drive unit to the steering column bracket.

Operating limits

•

The maximum internal operating temperature is 83 ºC (181 ºF).

If the controller reaches this point, it will automatically shut down to avoid damage. To view the current internal temperature of the controller, select

EZ-Steer Diagnostics.

Note — The internal temperature of the controller may be up to 12 ºC (22 °F) warmer than the external temperature.

•

The maximum operating voltage is 16 VDC. At this point, a warning is displayed and the system is automatically shut down.

CAUTION —

Do not supply voltages greater than 16 VDC to the EZ-Steer system, or you risk permanently damaging it.
