Section 2: Safety First
Read Before moving off
Never move the vehicle with a passenger in the cab unless the cab is fitted with an extra seat.
Always adjust the driver’s seat for proper control and comfort. Always fasten the safety belt before moving.
Make sure that all guards and closures are properly fitted and secure.
Before first use check the wheel nuts for tightness, then check daily.
Before starting the engine make sure that the parking brake is on and the transmission control lever is in neutral.
Do you understand the instructions and warnings conveyed by all the decals on the vehicle? Are all the decals still in place and
legible? Replace any decals that become damaged or dirty and illegible.
Your Knight 1800series self-propelled sprayer has excellent visibility to allow safe operation. Make sure that your windows are
clean so that you retain this advantage. Also, keep the cab interior clean, especially the controls.
Make sure that there are no flammable materials near the vehicle exhaust.
When moving off
Take extra care when reversing. Always make sure that there is no-one near the machine
Make sure your way is clear, remember that you are driving a high vehicle.
Always ensure 2 wheel steering is selected when leaving the field.
Move off slowly. Never exceed 40 km/h on the road under any circumstances. A lower maximum speed might sometimes be
appropriate if special equipment is fitted. Remember that all self-propelled vehicles have a much higher centre of gravity than tractors
and must therefore always be driven with more care.
When operating
Is your working area clear of obstructions, particularly overhead power lines. Remember the height of your vehicle and sprayer.
Always drive at a safe speed, having regard to ground conditions and the dangers posed by banks, ditches and slopes. Take extra
care when cornering when the ground is rough, slippery or sloping.
Take extra care when working up and down gradients, particularly in the use of the throttle.

07/06/2023 10
operators manual 1800v.doc
Always bring the vehicle to a controlled halt and engage the parking brake before dismounting from the cab.
When maintaining the vehicle
Care should be taken when working on the engine as it is fitted with the latest high pressure common rail fuel system and
exhaust aftertreatment system.
Never check the engine fuel lines for leaks when the engine is running or cranking.
Never loosen the high pressure fuel lines in order to remove air from the fuel system. This procedure is not required.
Do not work on the engine while it is still running or cranking. Allow 60 seconds after the engine has stopped before
commencing any work on the engine. This will allow any pressure in the high pressure fuel lines to be purged.
All maintenance should be done with the vehicle stationary, with the parking brake engaged, the transmission selector in neutral
and the engine switched off. Ensure the engine cannot be started.
Take care when re-fuelling with a hot engine. DO NOT SMOKE WHEN RE-FUELLING.
Never add coolant to a hot system, allow it to cool first and then take care to protect against scalding when releasing the radiator
cap.
If you are unsure what to do or how to do it, ask for advice. Although the vehicle components are robustly designed to withstand
tough operational conditions it is essential that they are properly set up and adjusted or the vehicle may be made unsafe or damaged.
Take extra care with electrical and electronic components and circuitry. Ensure battery isolator is switched off before any
maintenance is performed on the electrical system. Ensure the AdBlue system is purged before disconnecting the battery.
Make sure that any chemical contaminants are cleaned from any part of the vehicle before attempting maintenance and ensure
that the chemical residues are properly disposed of.
Always use axle stands after jacking up the vehicle. Do not work under the vehicle if supported only on jacks. When jacking,
make sure that the vehicle is restrained from moving by suitably placed chocks.
Take care with hydraulic fluids. They can be harmful to the skin. Use proper protective clothing and wash thoroughly any skin
that has contact. Take extra care if searching for hydraulic leaks by feeling or close examination. Hot, high pressure leaks of hydraulic
fluid are very dangerous to the skin and eyes.
Cautiously remove the following parts. To prevent spraying or splashing of pressurized fluids hold a rag over the part this is
being removed
•Filer caps
•Pressure taps
•Breathers
•Drain plugs
•Grease fittings

07/06/2023 11
operators manual 1800v.doc
After maintenance, make sure that all tools are safely put aside, that all guards and closures are fitted and fastened and the
vehicle is in a proper operational condition.
Report all necessary repairs
Engine Electronics
The engine has a Electronic Control Module (ECM) that monitors the engine operating conditions. If any of the engine
parameters extend outside an allowable range the ECM will initiate an immediate action.
The following actions are used as part of the engine monitoring control
•Warning
•Derate
•Shutdown
The following monitored engine operating conditions and components can limit engine speed and/or engine power
•Engine coolant temperature
•Engine Oil Pressure
•Engine speed
•Intake Manifold Air Temperature
•Supply voltage to sensors
•Fuel Rail Pressure

4 Wheel Steering
The 4 wheel steering system on the 2000
series is operated from the colour screen
control panel (figures 1+2)
System Logic (read before
operating)
The advanced logic of the Knight 4
wheel steering system allows selection
of two or four wheel steering
regardless of the current steering
position. There is no requirement for
the wheels to pass through the
straight ahead position before a mode
is activated.
To avoid sudden and dangerous rear axle movement the system incorporates an advanced logic that will only permit a slow creep
of the rear axle unless the operator is turning the steering wheel. This provides a very safe and smooth transition form two to four
wheel steering. N.B. When changing modes it is useful to remember that the closer you are to driving in a straight line, the
quicker the system will synchronise.
The steering system is fitted with a speed interlock. Only 2 wheel steering is available when high speed range is selected.
2 wheel steering (road) - Press the 2WS button on the control panel.
4 wheel steering (field) - Press the 4WS button on the control panel.
Foot Switch –The floor mounted switch located to the right of the steering column can be used to switch between two wheel and
four wheel steering. To select this mode of operation press the button indicated by a foot on the main control panel. The system
will now toggle between two and four wheel steering when the foot switch is momentarily pressed. The selected mode is
indicated by an illuminated symbol.
Spray Related Switching –If you prefer, the system can activate 4 wheel steering when the spray is off and 2 wheel steering
when the spray is on. To select this mode, press the button with a picture indicating a spray pattern. The system will now toggle
between two and four wheel steering when the spray is turned on and off. The selected mode is indicated by an illuminated
symbol.
Hillside Control - When spraying on side slopes there is a tendency for the rear of the machine to drift slightly downhill, to
compensate for this the Knight 2000 series is equipped with a hillside correction function. This function automatically steers the
rear wheels slightly uphill to compensate this drift, the amount of compensation can be adjusted using the hillside correction
adjust button. Figure 4 shows this button in use with the setting selected momentarily displayed.

Starting the engine
For safety reasons always ensure that you have completed all the safety checks detailed in Section 2 of this manual before starting and
moving off.
Switch the ignition key clockwise to the first ‘ignition on’ position.
Make sure that the parking brake indicator light is showing that the parking brake is engaged.
Make sure that the transmission lever is in the neutral (central) position. A warning will sound if it is not in the correct starting position.
Make sure that the PTO (Power Take-Off) switch (or switches if there is more than one) is/are in the off position.
If the horn sounds, the transmission oil level is low. Switch off the ignition and top up the oil. Check for leaks before and after starting
the engine.
Switch the ignition switch clockwise, against the slight pressure of the spring return to the next position to heat up the glow plug. The
glow plug will heat as long as the switch is held in this position. For colder engine starts, hold the key in this position for a little longer.
Turn the ignition switch further clockwise to the next position and hold against the spring loaded return. This engages the starter motor.
Release as soon as the engine fires. If the engine fails to fire after running the starter motor for 15 seconds, release the ignition switch.
Wait for a minute or so before re-trying the starting sequence.
The electronic throttle must be turned to the idle position before increasing the rpm. This is achieved by rotation it to the lowest setting.
Allow the engine to warm up before operating any engine-driven facilities. This is best done by running the engine un-loaded for a few
minutes at about 1200 rpm.
