2 DESCRIPTION

2.1 Drive

The machine has 4-wheel drive. The power from
the engine to the drive wheels is transferred hy­draulically. The engine drives an oil pump, which
pumps oil through the rear and front axle drives.

The front axle and rear axle are connected in se­ries, which means that the front wheels and rear
wheels are forced to rotate at the same speed.

To make turning easier, both axles are equipped
with differential.

Front-mounted implements are powered via drive
belts.

2.2 Steering

The machine is articulated. This means that the
chassis is divided into a front and a rear section,
which can be turned in relation to each other.

The articulated steering means that the machine
can turn around trees and other obstacles with an
extremely small turning radius.

2.3 Safety system

The machine is equipped with an electrical safety
system. The safety system interrupts certain activ­ities that can entail a danger of incorrect manoeu­vres. For example, the engine cannot be started if
the clutch-parking brake pedal is depressed.

The operation of the safety system must
always be checked every time before
use.

2.4 Controls

2.4.1 Implement lifter, mechanical (3:C)
(Pro16)

To switch between working position and transport
position:

1. Depress the pedal fully.

2. Release the pedal slowly.

2.4.2 Implement lifter, hydraulic (5:M)
(Pro20, Pro25, Pro Svan)

The hydraulic implement lifter only works when
the engine is running and the clutch pedal and
parking brake pedal are not depressed. The imple­ment lifter is controlled using the lever (5:M).

The lever has the following four positions:

Floating position. Move the lever to its
front position, where it locks. The imple­ment is now lowered to its floating posi­tion.
In the floating position, the implement
always rests against the ground at the

64

ENGLISH

same pressure and can follow the contours of the
ground.
Use the floating position when carrying out work.

Lowering. The implement lowers re­gardless of its weight.

Locking in the transport position. The
lever has returned to the neutral position
after raising and lowering. The imple­ment is locked in the transport position.

Raising. Move the lever to the rear posi­tion until the implement is in the highest
position (transport position). Then re­lease the lever to lock in the transport po­sition.

2.4.3 Clutch-parking brake (3:B)

4 STARTING AND OPERATION

The machine may not be operated un­less the engine casing is closed and
locked. Risk of burns and crushing in­juries.

4.1 Filling with petrol

Always use lead-free petrol. You must never use 2­stroke petrol mixed with oil.

The tank holds 14 litres. The level can easily be
read through the transparent tank.

NOTE! Ordinary lead-free petrol is a perishable
and must not be stored for more than 30 days.

67

EN

ENGLISH

Environmental petrol can be used, i.e. alkylate
petrol. This type of petrol has a composition that is
less harmful for people and nature.

Petrol is highly inflammable. Always
store fuel in containers that are made
especially for this purpose.

Only fill or top up with petrol outdoors,
and never smoke when filling or top­ping up. Fill up with fuel before starting
the engine. Never remove the filler cap
or fill with petrol while the engine is
running or still warm.

Never completely fill the petrol tank. Leave an
empty space (= at least the entire filler tube plus 1

- 2 cm at the top of the tank) to allow the petrol to

expand when it warms up without overflowing.
See fig. 8.

4.2 Checking the engine oil level

On delivery, the crankcase is filled with SAE 10W­40 oil.

Check the oil level every time before using to
ensure it is correct. The machine should be
standing on level ground.

Wipe around the dipstick. Unscrew and
pull it up. Wipe the dipstick.

Pro 16, Pro 20, Pro25:
Push the dipstick down completely and screw into
place.

Unscrew and pull the dipstick up again. Read off
the oil level.

Pro Svan:
Push the dipstick down completely without screw-
ing it into place. Pull it up again and read off the oil
level.

Top up with oil to the “FULL” mark if the oil level
is below this mark. See fig. 9-11.

The oil level must never exceed the “FULL” mark.
This results in the engine overheating. If the oil
level exceeds the “FULL” mark, the oil must be
drained until the correct level is achieved.

4.3 Safety checks

Check that the results of the safety checks below
are achieved when testing the machine in question.

The safety checks must always be car­ried out every time before use.

If any of the results below is not
achieved, the machine must not be

4.4 Start

1. Open the fuel cock. See 14.

2. Check that the spark plug cable(s) is/are in­stalled on the spark plug(s).

3. Check to make sure that the power take-off is
disengaged.

4. Do not keep your foot on the drive pedal (3:F).

5. Put the throttle control at full throttle.
Starting cold engine – pull the choke control out
fully.
Starting warm engine – the choke control
should be pressed in.

6. Depress the clutch-brake pedal (3:B) fully.

7. Turn the ignition key and start the engine.

8 Once the engine has started, push the choke

control in gradually if it has been used.

9. When starting from cold, do not make the ma­chine work under load immediately, but let the
engine run for a few minutes first. This will al­low the oil to warm up.

When the machine is in operation, full throttle
should always be used.

4.5 Power assisted steering

(Pro20, Pro25, Pro Svan)

Power assisted steering means that power from the
machine’s hydraulic system is supplied to the
steering wheel movements. This makes the ma­chine very easy to steer when the engine is operat­ing at working revs (full throttle).

The servo effect is reduced as the engine speed
drops.

4.6 Operating tips

Always check that there is the correct volume of
oil in the engine. This is particularly important
when operating on slopes. See 4.2.

Be careful when driving on slopes. No
sudden starting or stopping when driv­ing up or down a slope. Never drive
across a slope. Move from the top down
or from the bottom to the top.

The machine may not be driven on
slopes greater than 10º in any direction.

Keep hands and fingers well away from
articulated steering joint and seat
bracket. Risk of crushing injuries. Nev­er drive with the engine casing open.

4.7 Stop

Disengage the power take-off. Apply the parking
brake.

Allow the engine to idle 1-2 mins. Stop the engine
by turning off the ignition key.

Shut off the petrol cock. This is particularly impor­tant if the machine is to be transported on a trailer
for example.

If the machine is left unattended, re­move the spark plug cable(s) and re­move the ignition key.

The engine may be very warm immedi­ately after it is shut off. Do not touch the
silencer, cylinder or cooling fins. This
can cause burn injuries.

4.8 Cleaning

To reduce the risk of fire, keep the en­gine, silencer, battery and fuel tank free
from grass, leaves and oil.

To reduce the risk of fire, regularly
check the machine for oil and/or fuel
leakage.

Clean the machine after each use. The following
instructions apply for cleaning:

• When washing the machine with water under
high pressure, do not point the jet directly at
axle seals, electrical components or hydraulic
valves.

• Do not spray water directly at the engine.

• Clean the engine with a brush and/or com­pressed air.

• Clean the engine’s cooling air intake (9-11:W).

• Only Pro25: Clean the oil cooler (12:X).

Reduce the speed on slopes and when
making sharp turns in order to retain
control and reduce the risk of tipping
over.

Do not turn the steering wheel to full
lock when driving in top gear and at full
throttle. The machine can easily topple
over.

raise and lower the lifter 3-4 times.

12.Adjust the oil level in the reservoir.

5.7 Belt transmissions

After 5 hours of operation, check that all the belts
are intact and undamaged.

5.8 Steering

The steering must be checked/adjusted after 5
hours of operation and thereafter after 100 hours of
operation.

5.8.1 Checks

Briefly turn the steering wheel back and forth.
There must be no mechanical clearance in the
steering chains.

5.8.2 Adjustment

Adjust the steering chains if required as follows:

1. Put the machine in the straight-ahead position.

is no clearance.

4. Test drive the machine straight forwards and
check that the steering wheel is not off centre.

5. If the steering wheel is off centre, undo one nut
and tighten the other.

Do not over-tighten the steering chains. This will
cause the steering to become heavy and will in­crease wear on the steering chains.

5.9 Battery

If acid comes into contact with the eyes
or skin, this can cause serious injuries.
If any part of the body has come into
contact with acid, rinse immediately
with copious amounts of water and seek
medical assistance as soon as possible.

The battery is a valve-regulated battery with 12 V
nominal voltage. The battery fluid does not need to
and cannot be checked or topped up. The only
maintenance that is required is charging, for exam­ple after extended storage.

The battery must be fully charged be­fore being used for the first time. The
battery must always be stored fully
charged. If the battery is stored while
discharged, serious damage will occur.

5.9.1 Charging with the engine

The battery can be charged using the engine’s gen­erator as follows:

1. Install the battery in the machine as shown be­low.

2. Place the machine outdoors or install an extrac­tion device for the exhaust fumes.

3. Start the engine according to the instructions in
the user guide.

4. Allow the engine to run continuously for 45
minutes.

5. Stop the engine. The battery will now be fully
charged.

5.9.2 Charging using battery charger

When charging using a battery charger, a battery
charger with constant voltage must be used.
