COOLING THE CAB

For fast cooling the inner space of cab move the heating shut off lever (2) into the left position (i.e. fresh air inlet is closed). Choose the desired blower speed by the four speed blower switch (position 1, 2, 3). Set outlets with desired angle to avoid direct blowing to persons in the tractor cab (possible injury because of intensive cooling of person řs body).

AC OPERATION

With switched AC and permanently closed heating shut off  lever (2) in left position (i.e. fresh air circuit closed) the inner air is breathed out. Persons could become tired. Thatřs why we recommend do move the lever (2) into the right position (fresh air opened) immediately after cooling down and reduction of the inner temperature to desired level. The fluent regulation of system is carried out by partial opening of the heating valve with heating control lever (3). At the same time dry air from AC system becomes moisture by this way.

FUNCTION OF ELECTRONIC GOVERNOR

1. Setting the temporary memory

2. Resetting and deleting the temporary memory

3. Setting the permanent memory

4. Permanent memory recall - H/O lamp is off

5. Permanent memory recall - H/O lamp is on

6. Memory reset - return to pedal control

Engine speed, determined for memorizing to memory system, can be set either by throttle control or by foot throttle control (throttle pedal). Enter, recall and reset of memory is possible on the keyboard of hand throttle control.

SETTING THE TEMPORARY MEMORY

1. Indicator lamp H/O must be off.

2. Set the desired engine speed by hand (keypad MIN or MAX) or foot throttle control, for example 1600 RPM.

3. Press the keypad MEM; indicator lamp H/O turns on.

4. Set engine speed 1600 RPM is memorized.

Since this setting, it is not necessary to set the engine speed anymore. You can loose the foot throttle pedal. Engine speed is maintained in the constant level (for example 1600 RPM) temporarily memorized, independently upon tractor load.

RPM7 RPM8 RPM9

With such way set constant value (for example 1600 RPM) it is possible to set the engine speed by means of hand or foot throttle control and the entered memory will not be lost. a -

You can increase or decrease the

engine speed by hand throttle control. Increase or decrease the engine speed by interrupted pressing of keypad MIN or MAX.

b - You can only increase the engine

speed by foot throttle control. After loosing the foot throttle pedal the engine speed drops again to the value entered in temporary memory (for example 1600 RPM).

In case the minimal engine speed is

1. being entered it is not possible to enter the value higher than 1500 RPM. If you will try it the system will automatically enter 1500 RPM.

2. In case the maximal engine speed is being entered it is not possible to enter the value smaller than 1500 RPM. If you will try it the system will automatically enter 1500 RPM.

ELECTRONIC ENGINE GOVERNOR

Two values can be entered into permanent memory i.e. chosen minimal and maximal engine speed. These values will be memorized in the permanent memory even after stopping the engine and removing the key from the key switch. If you will enter the new minimal and maximal engine speed into the permanent memory the previously entered values will be deleted and replaced by new ones i.e. new values set by you.

PERMANENT MEMORY RECALL - H/O LAMP IS OFF

1. Indicator lamp H/O is off.

2. Press the keypad MIN or MAX (depending if you want to recall maximal or minimal speed entered in memory) and keep it pressed (longer time than 0,5 sec.).

3. Indicator lamp H/O turns on. Memory is recalled. Engine will maintain the recalled constant speed.

Engine speed can be set after this action by:

RPM13 RPM14 RPM15

HYDRAULIC TRAILER BRAKES

Hydraulic trailer brake control is synchronized with braking the tractor including the braking effect. Operating pressure is activated by pressure of oil from hydraulic pump (1). The hydraulic valve (2) is introduced in the circuit of hydraulic pump. The hydraulic pump is of gear type (pump can not be disengaged). The hydraulic trailer brake valve is controlled by the brake fluid pressure activated in master brake cylinder depending upon the force on brake pedal. The pressure in brake coupling (4) must be 12 - 15 MPa at maximal press on the brake pedal. Trailer brake valve prioritizes the function of brake to control of hydraulic. Do not forget to bleed the trailer brake valve (2) by vent screw (3) when bleeding the service brakes. In case there are hydraulic shocks in hydraulic circuit if applied service brake pedals it is necessary to bleed the hose (5) coming from brake valve (2) to quick-coupler (4).
