Dear IRUS Customer,
You have made your decision for an IRUS machine. We would like to thank you for the trust you have
placed in us.
It is our desire that you will have just as much satisfaction with your IRUS machine as many thousands of
other IRUS customers have had in the past. This, of course, depends heavily upon a detailed knowledge of
the proper use of the machine. Before you begin using the machine, please have your sales representative
give you a detailed explanation and demonstration of the machine. Then, by all means, familiarize yourself
with this instruction manual. Although our devices are known by their simple operation and maintenance, it
is nevertheless important that you know as much as possible about the machine, because an incorrect
operation of the machine can lead to damages for which you must pay, even though they may take place
during the warranty period.
The safe handling and proper use of the machine will therefore be to your own benefit. So please keep in
mind that it is also up to you to really enjoy your new IRUS machine.
Warranty conditions:
We provide our equipment with a warranty for the period specified in the warranty card. During this time,
we will replace all parts which prove to have material or manufacturing defects. On the other hand, there is
no warranty for wearing parts such as starter ropes, V-belts, Bowden cables, etc., or for broken parts
caused by improper handling, lack of maintenance and care, or caused by failure to comply with the
operating instructions. If, during the warranty period, non specialised personnel attempt to repair the
machine themselves, this will void the warranty. Should any parts be installed that are not original IRUS
parts, this would also void the warranty.
Engines, which are not of IRUS manufacturing, are subject to the warranty conditions of their respective
manufacturers.
Important notice!
The enclosed warranty registration card is to be completed and signed by you and your dealer, and sent to
us immediately after the purchase of the equipment. No warranty will be recognized if no warranty
registration card has reached our office.
And now we wish you much satisfaction with your IRUS machine!

Safety requirements and accident prevention regulations
Prior to the commissioning of the machine, the users must familiarize themselves with the operating and
safety regulations listed in the operating instructions. The safety regulations must be correctly observed
and all safety information passed on to others who operate this machine.
The UNITRAK implement carrier may only be operated in connection with original IRUS attachments,
according to manufacturer specifications. The operating instructions must be strictly observed, as IRUS will
assume no liability for damages resulting from neglect. The intended use of IRUS machines also includes the
observance of the operating and maintenance conditions prescribed by IRUS, as well as the exclusive use of
original IRUS spare parts. Unauthorized changes on the machine and the attachments will nullify any
liability of the manufacturer for damages resulting there from.
The warning and information signs attached to the device provide guidance for a
safe operation. Observing these signs is for your own safety and protection!
Always use gloves when handling the machine or mowing with the machine!
Always wear goggles and gloves when knife grinding!
The relevant accident prevention regulations, as well as the generally accepted technical, occupational
health and road traffic safety regulations must be strictly observed.
The operator bears the responsibility for the safety of people and animals that may find themselves within
the working area of the machine, and must take precautions that no third party is endangered or injured.
Children under 16 years are not allowed to operate the machine!
The operator must wear sturdy shoes and tight-fitting clothing.
Do not fill any fuel into the fuel tank whilst the engine is running or if it is still hot. Be careful to wipe up any
spilled fuel before starting the engine!
FIRE hazard!
Before starting the engine, the coupling lever must be pulled back and locked into place. The power take-
off lever as well as the control lever must be in the neutral (0) position.
When starting, nobody must be lingering in front of the machine.
Apply the throttle gently; a jerky movement could force the machine to tilt up on end.
Never leave the ignition key in the ignition switch (if electrically started).
The machine is never to be left unattended whilst the engine is running.
When working, be sure all safety guards are properly mounted.
After cleaning and after repair, all safety guards must be immediately reinstalled.
The machine operator must always maintain his distance to the machine as indicated by the steering bars.
Turn off the engine to do work of any kind on the machine. Cleaning is not recommended by hand, but
should be done using a suitable object between the spaces (a piece of wood or the like).
Should the machine be at risk of tipping over due to sloped terrain, an accompanying person may support
the machine by means of a holding rod or a guide rope. This accompanying person must be located above
the machine at a sufficient distance from the working tools.
Rain and/or moist soil increase the risk of slipping. If possible, therefore, only work on slopes or hillsides
with the weather permitting.
When starting the engine, the operator should not place himself in front of the machine or work tools.
Pacemaker carriers must not come in contact with current-carrying cables of the ignition while the engine
running.
No non-participating personnel must be allowed to come within the danger area!
Never start the engine in a closed room!
Internal combustion engines must not be operated in closed rooms; unless it can be assured that the
combustion gases are actively removed from the room. The exhausts contain hidden and odourless, but
highly toxic carbon monoxide. Attention:
Mortal Danger!
Attention!
For your own safety, all Bowden cables must be examined before every start-up. The area subject to wear
and tear on Bowden cables is where the cable exits the casing and around the area of the operating lever.
The function of the stop or deadman lever is also to be checked. In the case of defective Bowden or
deadman controls, the machine must not be put into operation, or all running operations must be
immediately stopped.
IRUS absolutely requires that you have your IRUS machine inspected for safety by an authorized repair shop
at least once a year.
General Description:
The basic
IRUS
UNITRAK
machine is a multi-functional tool carrier with infinitely variable hydrostatic drive.
Each wheel is driven by a separate hydraulic motor. The oil supply of these motors is provided by a variable
pump. With this propulsion machine, various attachments can be driven. All attachments are taken up by
the quick coupler and driven by the PTO shaft.
General Description:
Engine:
The
IRUS UNITRAK
is available with different engines (see separately enclosed operating manual for the
engine).
During the first 20 hours of operation (running-in time), the engine should not be taken to the limit of its
capacity. Cooling is provided by an air blower. For this reason, the grid for the cooling air and the cooling
fins of the cylinder should always be kept free from dirt and intake debris. It is important to make sure that
the engine idling speed is set correctly. The engine must continue to run properly at low rpm when the
throttle lever is fully at the stop in the idle position. The setting is to be made as described in the engine
manual.
Air Filter:
The air filter has the task of intercepting the dust contained in the intake air. Cleaning must be performed
regularly; even several times a day in case of heavy dust onset (see engine instructions). When noticing a
decline in engine power, always think first of cleaning the filter.
Coupler:
A triple-plate dry coupler serves as a multi-plate coupler.

This is done as follows:
01. Pull out latch lock (Fig. 1/4) upwards and rotate 90°.
02. Mount devices (slide them into the quick coupler [Figure 2/3]).
03. Rotate latch lock again to 90 degrees and let it lock into place again. Make very sure that it has locked
into place!!!
Driving:
The
IRUS UNITRAK
is equipped with a variable drive system. By pushing the control lever (Fig. 2/7)
upwards, the machine is set in forward motion. The further the lever is moved, the faster the machine runs.
By moving the lever back, the machine slows down again. In the idling position, a catch can be felt on the
lever. The intensity of the latching can be adjusted (see maintenance work).
By pressing the control lever (Fig. 2/7) downward, the machine moves backwards in motion. The reverse
speed is also variable.
PTO:
The PTO is switched on by moving the lever (Fig. 1/5) forward. By moving the lever backward the PTO is
switched off.
Switching on:
01. Pull coupler lever (Fig. 1/7).
02. Move lever (Fig. 1/5) forward.
03. Let go the coupler lever (Fig. 1/7) slowly.
Switching off:
01. Pull coupler lever (Fig. 1/7).
02. Move lever (Fig. 1/5) backward.
03. Let go the coupler lever (Fig. 1/7) slowly.

ground.
Transportation of the machine:
Attention:
DANGER!
Before transporting the machine, turn off the engine and wait for the cutting tools to come to a complete
halt. The machine must be fastened according to the regulations in four directions. When driving the
machine outside of the working area, the attachment must likewise be switched off and the cutting tools
come to a complete halt.
Steering:
The
IRUS UNITRAK
is so designed that it always has the tendency to go straight ahead. Do not try to control
the machine forcibly at the steering bar. This is not necessary because the machine has an active steering
system.
The active steering system:
If you want to turn right, you only need to press the steering bar to the left and the machine moves to the
right. By
pressing the steering bar to the right, the machine moves to the left. Depending on how hard
you
press, the machine turns sharply, even with a jerky motion, or it moves gently into the curve. As soon as
you leave off from pushing to the sides, the machine drives straight ahead again.
WARNING!
Always work slopes going uphill only! RISK OF ACCIDENTS!
Moving the centre of gravity:
To be able to drive the machine comfortably while using various heavy attachments, the
IRUS UNITRAK
has
an adjusting axle.
If the axle is moved forward, the weight is shifted backwards, i.e. the pressure upon the mounting device is
less. The attachment can be lifted with less force upon the steering bar. If the axle is moved all the way
back, it is just the opposite. For every attachment, you need to choose the most convenient position.
Adjustment of the axle:
01. Loosen the four Allen screws on the right and left (Figure 4/2).
02. Operate the control lever (Fig. 2/5) in the direction in which you want to adjust the axis.
03. Torque up the four Allen screws again, right and left.
