trol
Inj min
1. Disconnect the ball joint of the connecting
rod between the servomotor and injection
pump from the lever of the servomotor.
2. Adjust the mechanical restriction of the
minimum position of the engine injection
pump lever to a position where the lever
rests on the mechanical minimum restric-
tion screw and the engine speed falls short
of the chart value by 50 ... 100 rpm (in
1710B, for example, 800 ... 850 rpm).
3. Set the ’Inj min’ value to 110 (the diesel en-
gine is not running, the TMC power is on).
4. Adjust the length of the connecting rod bet-
ween the servomotor and the injection pump
precisely to a level that makes it possible to
freely position the rod into its place.
5. Next, start the engine.
6. Allow the engine to idle and adjust the ’Inj
min’ value until the diesel engine speed cor-
responds to the ’Rpm min’ rating given in
the chart (for an 1710B, for instance, it is
1000 rpm).

3. Functional Requirements for

Outputs
3.1 General
The function of the seat safety switch is a prereq-
uisite for all outputs. In other words, no function
can be activated unless the operator sits on the
seat. When using the crane controls, articulated
frame steering stick or the accelerator pedal, it is
possible to stand up for a moment and the func-
tion will not be interrupted, but when engaging
a function the operator must always be seated.
3.2 Function of Driving Power Trans-

mission
3.2.1 Displacements And Control Currents

of Drive Pump And Motor Control
A Function
TMC adjusts the angles of the transmission
pump and the hydraulic motor on the basis of in-
formation from the controls and on the basis of
the load.

Page Issue
3-2 01/00-07
B Requirements
- After releasing the parking brake the driving
direction selector must be shifted into neutral
for a brief moment and, similarly, the acceler-
ator pedal must be released to the upper posi-
tion (dead zone).
- The stairs are up.
- The high or low gear is engaged.
- The engine is running (oil pressure).
- There are no alarms activated that would pre-
vent driving.
The machine speed and the pump and motor
control current will change in relation to the
position of the accelerator pedal.
The motor current will start increasing from the
zero level the moment the machine starts moving.
If TMC does not have a signal from rpm sensor
of the transmission motor, it does not give con-
trol current to the motor. The maximum speed of
the machine is then 3 km/h in a low gear. In this
case there is no display either driving speed or
trip odometer.

Issue Page
01/00-07 3-3
3.2.2 Engine Speed Control

A Function
The position of the fuel injection pump is con-
trolled by means of a servocontrol (up/down).
Feedback data (Inj.Pos) will be given of the in-
jection pump position. The function below de-
scribes the interdependency between the engine
revolutions (corresponds to the position of the
injection pump) and accelerator position.
Working/ Inching
Pedal position (%) = The position of the acce-

leration pedal.
Engine rpm = The engine speed
Working = The engine working rpm
Inching = The engine constant speed
Basic = The normal engine speed
Deadband = The point where the dead zone
ends and the function is engaged.
B Requirements
For cold-weather starting purposes the position
of the servomotor is in relation to the position of
the accelerator pedal (as indicated in the illustra-
tion).
The output controls a valve opening the LS line
directly into the tank, so that the working pres-
sure cannot go up.

Page Issue
3-4 01/00-07
3.2.3 High/Low Gear
A Function
The high gear is engaged by the high gear output.
Similarly, the low gear is engaged by the low
gear output.
When shifting the pump receives short impulses
back and forth for five seconds. This is to ensure
that the shifting process is successful. Driving is
prevented until the gear engagement is detected
by the gear control switch.
B Requirements
- The low gear goes on as the machine is
switched on.
- The high/low gear shifting is possible in case
the parking brake is released, the service
brake is engaged and the driving direction se-
lector is in neutral.
- To switch between a low and high gear, use
the hare button on the right hand side arm-
rest.

Issue Page
01/00-07 3-5
3.2.4 Service Brake
A Function
The service brake is engaged by the output.
B Requirements
The output will be activated if the following re-
quirements are met:
- The parking brake is disengaged.
- If the machine comes to a halt within one sec-
ond after the pump current of the driving
power transmission has dropped below the
minimum current level.
- The power transmission stands still, the ma-
chine does not move.
3.2.5 Release of Rear-Wheel Drive (For-

warders) Or Front-Wheel Drive (Har-
vesters)
A Function
If the output is activated the rear-wheel drive of
the forwarder and the front-wheel drive of the
harvester will be released.
B Requirements
The output will be activated if:
- The high gear has been engaged and the rear-
wheel drive (front-wheel drive) switch is not
pressed.
The output will be deactivated if:
- The low gear has been engaged or the rear-
wheel drive (front-wheel drive) switch is
pressed.

Page Issue
3-6 01/00-07
3.2.6 Differential Lock; Front-Wheel Drive
A Function
The front axle differential lock is engaged by the
output.
B Requirements
The output will be activated if:
- The machine does not move and the differen-
tial lock switch is pressed.
The output will be deactivated if:
- The machine does not move (the service
brake will be engaged within a second) and
the differential lock switch is not pressed.
3.2.7 Differential Lock; Rear-Wheel Drive

This output only applies to forwarders and the
function does not differ from that of front-wheel
drive outputs.

Issue Page
01/00-07 3-7
3.2.8 Release of Frame Brake
A Function
The output shifts the frame brake valve which
blocks the pressure from the lift cylinder and
connect the frame brake pressure to the tank.
B Requirements
The output will be activated if the following re-
quirements are fulfilled:
- The driving direction is engaged.
- The service brake is disengaged.
- The release switch of the frame brake is acti-
vated.

Page Issue
3-8 01/00-07
3.2.9 Excitation Valve of Working Pump
A Function
The output controls the hydraulic pump excita-
tion valve which reconnects pump pressure to
the pump’s LS line.
B Requirements
The output will be activated if optional accesso-
ries are used (for example: the headboard move-
ment, dozer blade, clambunk or grapple saw)
(Forwarders).
3.2.10 Unloading of Working Pump
A Function
What is controlled by the output is the relief valve
of the working pump of the hydraulic system. The
valve opens the line between the tank and the LS
line, thus unloading the working pressure.
B Requirements
The output will be activated when the parking
brake is on.
This output is enabled in case one output of the
crane module has a malfunction.

3.3 Crane Module
3.3.1 Control of Crane Valves And Articu-

lated Frame Steering Valves
The control outputs of the crane function valves,

accessory valves and articulated frame steering
valves are all similar. This is why the following
description applies to all crane control outputs.
A Function
The function below indicates how the current of
the crane valves depends on the position of the
crane controls with various progression values.
Let us look at the example: The minimum cur-
rent is 200 mA, maximum current 450 mA, dead
zone 10 % and the progression values are 0 %,
20 %, 40 %, 60 %, 80 % and 100 %.
VALVE CONTROL CURRENT (mA)
JOYSTICK POSITION (%)
Joystick position (%)

Valve control current (mA)
Deadband = The point where the dead zone ends
and the function is engaged.
NOTE! After engaging the crane functions, the

control sticks must first be shifted to the center
position before the crane can be operated.

Page Issue
3-10 01/00-07
B Requirements
The requirements apply to crane functions and
accessories. There are no requirements for the
function of the articulated frame steering.
If the output current is to follow the function
above, the following requirements must first be
fulfilled:
- The crane is engaged.
- There are no alarms activated that would stop
operation.
