1 Introduction

1.1 Information on the operating manual

This original operating manual contains important information on how to operate the Citymaster safely, properly and economically. It is, therefore, not only intended for newly trained operating personnel but also as a reference manual for experienced workers. It helps prevent risks and to reduce repair costs and downtimes. In addition, it also helps increase the reliability and service life of the vehicle. For these reasons, the operating manual must always be available in the vehicle.

Your own safety, and that of others, basically lies in your ability to control and operate the vehicle. Therefore, read this operating manual thoroughly before driving the vehicle for the first time. The operating manual will help you become familiar with the vehicle more quickly and be able to use it safely and effectively.

Before driving the vehicle for the first time, ensure you read the Chapter "Safety Information" in order to be prepared for any dangerous situations which could arise. It is too late to do this when work has actually started! The following basic rule applies:

Working considerately and carefully provides the best protection from accidents!

Operational safety and deployability of the vehicle are not only dependent on your working capabilities but also on the servicing and maintenance performed on the vehicle. For this reason, regular maintenance and service work are absolutely essential. Larger scale maintenance and repair work should always be carried out by appropriately skilled staff. Only original spare parts may be used for repairs. You then have the guarantee that the vehicle's operational safety, deployability, prescribed condition and worth are retained.

Should you have any questions in respect of the vehicle or operating manual, your authorized Hako dealer is available to provide help at any time.

We strongly recommend that you read this manual before you put the Citymaster into operation!

3.3.6 Brakes

General information The level of wear of the brake linings is heavily dependent on:

• the conditions of use, e.g. short or long travel distances,

• flat land, hills,

• manner of driving.

Therefore, it may be necessary to have the brake linings checked between the maintenance intervals specified by your authorized Hako service center.

The braking effect may be negatively affected by:

• wet and/or cold,

Apply the brakes until they are dry.

• de-icing salt,

The salt layer on brake discs and brake linings must first be worn off

during braking.

• overheating

Do not "ride" the brakes by pressing the pedal lightly. When driving downhill, reduce speed in time. Exploit the braking effect of the diesel engine. During long downhill routes, apply the brake at additional intervals. Drive carefully and with foresight.

Danger!

The braking effect can change in certain operating conditions, such as after driving through puddles of water, driving in heavy rainfall, after cleaning the vehicle or driving on de-ice salted roads!

Risk of accident!



The brakes must be ground in again by driving slowly and carefully actuating the brake pedal!

Brake booster The brake booster operates by means of a negative pressure which is

only produced when the engine is running.

Danger!

The brake booster does not work when the engine is switched off. The brake pedal has to be pressed in much harder! Take this into account, especially when towing the vehicle!

Risk of accident!



Use a tow-bar whenever possible!

The brake control lamp 93 lights up to indicate the brake fluid level is too low.

X56b320.fm 3-33

Operation

Hand brake lever (parking brake)

Function

• To park the vehicle and secure it against rolling away (parking brake).

• Emergency brake should the service brake fail.

Danger!

The parking brake may only be used as a service brake in an emergency, i.e. if the service brake fails. The brake lights donot light up in this case. Risk of accident!

Bring the vehicle to a service center immediately. In normal operation, only the brake pedal 54 is used as the service brake because this causes the rear brake lights to light up.

The braking power of the parking brake is determined by the rear wheel with the least friction value to the driving surface. When the vehicle is parked on a slope with one rear wheel parked on solid and dry ground while the other rear wheel is parked on ice or snow, the maximum brake power is determined by the friction factor between the wheel and the ice. If the vehicle rolls away, it represents a risk of accident!

When parking on a slope, also switch on all-wheel drive. When parking on a slope, secure the vehicle with wheel chocks!

Preventing the vehicle from rolling away

Pull the hand brake lever 63 upwards to apply the parking brake.

• The warning light 94 lights up.

You should notice firm resistance after pulling past 6 to 8 latching points.

• If not, the parking brake is not in working order!

 Have the parking brake inspected by a specialist immediately.

Releasing the parking brake

Pull up the hand brake lever slightly, press in the button A on the hand

brake lever and move the hand brake lever downwards.

• The parking brake is released and the warning light 94 goes out.

While driving, only use the parking brake as an auxiliary brake in an emergency. PARKING BRAKE! appears in the multifunctional display.

In an emergency, pull the hand brake lever 63 upwards, forcefully.

Note!

The hand brake lever acts on a separate brake drum on the gear shaft via a brake cable.

Fig. 17:

3-34 X56b320.fm

Operation

Brake pedal

Function

• Decelerates the vehicle.

Actuating the service brake

Press the brake pedal 54 down according to the braking effect required

Note!

When the vehicle is fully loaded, a higher braking pressure is required to decelerate it.

• The pedal travel foot power which must be applied increases.

• The maximum braking effect which can be achieved with a loaded vehicle is reduced as compared to an unloaded vehicle.

Danger!

When a brake circuit fails (brake warning light 93 lights up), the

pedal can be pressed through much further and the braking effect which can be achieved is considerably lower. There is a

Risk of accident!



Press the pedal in further, quickly

Stop the vehicle in a safe place without delay. Clear the cause of the noise or loss of brake fluid (or have it

cleared)

Check the brake fluid level, correct it as necessary; refer to

Chapter "Maintenance".

Fig. 18:

X56b320.fm 3-35

Operation

3.3.7 Steering

Danger!

In the case of failure of steering assistance: Turning the steering wheel requires greater effort! Take this into account, especially when towing the vehicle! The vehicle is no longer operational and represents a

Risk of accident



Drive the vehicle to the next possible parking area!

Adapt the towing speed to the altered steering behavior!

Note!

The steering system is only operational when the engine is running! If the diesel engine breaks down or the hydraulic powered steering fails (e.g. due to breakdown of the pump drive), the vehicle can still be steered – emergency steering facility.

Do not leave the steering wheel in a full lock position for more than 15 seconds. A continuous full lock causes the servo pump to heat the hydraulic oil very strongly. This can damage the servo steering system.

Every full lock while at a standstill is also noticeable through noise because of the strong load applied to the servo pump. In addition, the idle speed of the engine is reduced for a short time.

Steering column adjuster The height and inclination of the steering wheel and steering column 47

can be adjusted to suit each driver. Adjust the steering column as follows before starting to drive

Fig. 19:

• Front wheel steering, for transport mode when driving to work sites on

roads, and for work mode.

• All-wheel steering (only available in work mode).

All-wheel steering is automatically activated on selecting work mode.

Danger!

Only change the steering mode when the vehicle has stopped.

Risk of accident



First, stop the vehicle.

Synchronize the steering.

Note!

Before changing over to transport mode after termination of operating with four-wheel drive, stop the vehicle and turn the steering wheel slowly to the left or the right past the straight ahead position.

3.3.8 Traction drive

Selecting the driving mode The Citymaster has two driving modes available for selection, one for driv-

ing in respect of driving to a work site and one for driving when completing work. Select the modes as recommended below according to the type and duration of use.

Automotive drive

This represents the normal driving mode (transport mode) when driving the vehicle on public roads between work sites. The vehicle is then driven in the same way as a "car":

The driving direction is selected with the drive lever 64 on the steering

wheel column.

Tread on the accelerator pedal 55 to move the vehicle in the direction

selected to its maximum speed.

Cruise control Use the switch 119 to drive the vehicle at a constant speed. Accelerate/

Decelerate to the desired speed (min. 2 kph) with the accelerator pedal and then press the switch to accept it.

Cruise control is interrupted by actuation of the brake or by pressing the tip switch.

Danger!

Increased risk of accident due to reduced caution of the driver and due to delayed braking (according to position of the foot).

Risk of accident



Keep foot ready to apply the brakes.

Increased vigilance.

X56b320.fm 3-39

Operation

Accelerator pedal

Different drive modes are available which can be selected according to the task at hand. Normally, the vehicle is operated in automotive mode. In this case, the accelerator pedal 55 regulates the speed of the diesel engine:

Note!

The maximum speed possible is dependent on the drive mode selected with the tip switch 115. The strong braking effect of the hydrostatic drive which occurs when the accelerator is suddenly released represents a risk of the wheels on the rear axle blocking in the event of bad weather condition (wet or dirty roads, ice and/or snow)! When the vehicle brakes are applied abruptly with the hydrostatic drive or the foot is removed from the accelerator pedal suddenly, the brake lights are switched on to warn following traffic.

Attention!

In the case of hydraulic oil temperatures under 10 °C, the diesel engine speed is reduced by the drive control to prevent damage to the hydraulic pumps.

Attention!

The drive control is limited by a sensor on the pressure filter in the case of a soiled pressure filter. Under certain conditions, the vehicle no longer reaches top speed. The "PRESSURE FILTER SOILED!" warning message appears. Replace the pressure filter cartridges!

Press the accelerator pedal 55 down slowly. Test the brakes while dr ivin g slow ly. Allow the engine to warm up before moving to top speed.

Note!

The vehicle only pulls away when the driver is seated on the driver's seat (seat contact switch).

3.4.5 Driving

The driving speed is determined by means of the infinitely variable accelerator pedal 55. Depending on the tires, the vehicle reaches top speed on level ground at an engine speed of 2700 to 2900 rpm. This means that, after completing the accelerating phase, the accelerator pedal 55 can be withdrawn a little without the driving speed being affected. This actively contributes to reduction of noise and fuel consumption.

In order to achieve maximum acceleration or the maximum speed when driving up a slope, drive at full throttle so that the diesel engine operates at its rated horsepower at approx. 3100 rpm.

Attention!

In the case of hydraulic oil temperatures under 10 °C, the diesel engine speed is restricted by the drive control to prevent damage to the hydraulic pumps. If the hydraulic pump pressure filter is soiled (warning message PRESSURE FILTER SOILED! appears in the multifunctional display), the hydraulic pump no longer supplies the full flow rate and the vehicle does not reach its top speed.

Operation

3.4.6 Stopping the vehicle

Decelerating

Release the force applied to the accelerator pedal 55 and move the

drive lever 64 slowly to its neutral position.

Press down on the brake pedal 54 gently.

Note!

When the vehicle brakes are applied abruptly with the hydrostatic drive or the foot is removed from the accelerator pedal suddenly, the brake lights are switched on to warn following traffic.

Stopping

Take your foot from the accelerator pedal 55. Press the brake pedal 54 until the vehicle has stopped. Move the drive lever 64 to its neutral position. Pull up the hand brake lever 63.

• The warning light 94 lights up.

3.4.7 Stopping / Parking the vehicle

Danger!

If the vehicle is stopped on slopes, it could roll away.

Secure the vehicle from rolling away by applying the parking

brake!

Also secure the vehicle by placing chocks under the downhill

sides of the wheels!

Stop the vehicle. Apply the parking brake.

After operation at full power:

Allow the engine to run on for approx. 60 sec. so that the temperature

can stabilize.

Switch the engine off by turning the ignition key to position "0". Remove the ignition key. Lock the doors after getting out of the driver's cab.

On slopes:

Also secure the vehicle by placing chocks under the wheels on the

Operation

3.4.8 Differential lock (option)

The differential lock can be used when one wheel on the rear axle spins and it is not possible to drive on.

The differential lock can only be activated in work mode. When the differential lock is activated, a rigid connection of the drive shaft

transfers the drive torque to both wheels on the rear axle evenly.

Attention!

If the differential lock is switched on incorrectly, it is possible that the differential of the rear axle will be damaged. The differential lock can only be switched on when:

• the drive is not under load,

•the wheels are not spinning.

Differential lock switch The differential lock of the is activated by pressing the button 118.

Note!

The differential lock can be switched on while driving, but only if the wheels are not spinning, i.e. as long as the wheels turn with ground contact and only while driving straight ahead. The differential lock engages after the occurrence of low speed differences by the wheels of rear axle (e.g. when cornering). The differential lock only remains active as long as the tip switch is pressed. Driving on firm ground with the differential lock switched on increases tire wear. Never use the differential lock longer than necessary.

3.4.9 Towing and transporting the vehicle

Safety information • Only tow the vehicle using appropriate towing equipment (towing rope

A) in conjunction with suitable towing facilities B, such as towing hitch,

hook, eye (refer to figure)! In this case, unscrew the 3rd sweeping brush.

• Accelerate slowly! Pay attention that there are no persons in the area of

the tow-bar.

• The vehicle may only be towed using the towing rope when the service

brake and steering are functional!

When loading and transporting the vehicle:

• The transporting vehicle must be of adequate size – refer to Section

Specifications for the dimensions of the vehicle!

• Remove any mud, snow or ice from the tires so that the vehicle can be

driven safely onto ramps.

• Secure the vehicle against unintentional movement! The best positions

to secure the vehicle are the front and rear wheels.

Towing the vehicle

Danger!

If the diesel engine has broken down, strength is required to turn the steering. The brake booster does not work when the engine is switched off. The brake pedal has to be pressed in much harder! Take this into account, especially when towing the vehicle!

Risk of accident!



Drive the vehicle to the next possible parking area!

In the case of cold hydraulic oil, load the vehicle, do not tow it! Maximum towing speed: 10 kph! Towing is only permitted with front wheel steering! Use a tow-bar whenever possible!

Attention!

If the drive lever 64 is not in its neutral position when the engine is running and the switch 72 has not been actuated, the vehicle must not be towed! The hydrostatic drive could be damaged by towing!

When the engine is running:

Tow the vehicle at max. 10 kph and for max. 10 km!

When the engine is off:

Tow the vehicle at max. 5 kph and for max. 2 km!
