9. When starting from cold, do not make the ma-
chine work under load immediately, but let the
engine run for a few minutes first. This will al-
low the oil to warm up.
When the machine is in operation, full throttle
should always be used.
7.6 Operating tips
Always check that there is the correct volume of
oil in the engine. This is particularly important
when operating on slopes. See 7.2 Checking the
engine oil level.
Be careful when driving on slopes. No
sudden starting or stopping when driv-
ing 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.
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.
Keep hands and fingers well away from
articulated steering joint and seat
bracket. Risk of crushing injuries. Nev-
er drive with the engine casing open.
7.7 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 impor-
tant if the machine is to be transported on a trailer
for example.
If the machine is left unattended, re-
move the spark plug cable(s) and re-
move the ignition key.
The engine may be very warm immedi-
ately after it is shut off. Do not touch the
silencer, cylinder or cooling fins. This
can cause burn injuries.
7.8 Cleaning
To reduce the risk of fire, keep the en-
gine, 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 com-
pressed air.
• Clean the engine’s cooling air intake (20:T).
8 MAINTENANCE
8.1 Service programme
In order to keep the machine in good condition as
regards reliability and operational safety as well as
from an environmental perspective, GGP’s Service
programme should be followed.
Servicing carried out at an authorised workshop
guarantees professional work using genuine spare
parts.
8.2 Preparation
All service and all maintenance must be carried out
on a stationary machine with the engine switched
off.
Prevent the machine from rolling by al-
ways applying the parking brake.
Stop the engine.
Prevent unintentional starting of the
engine by disconnecting the spark plug
cable(s) from the spark plug(s) and re-
moving the ignition key.
8.3 Tyre pressure
Adjust the air pressure in the tyres as follows:
Front: 0.6 bar (9 psi).
Rear: 0.4 bar (6 psi).
8.4 Changing engine oil
Change engine oil for the first time after 5 hours of
operation, and subsequently after every 50 hours
of operation or once a season.
Change the oil more often (after 25 hours of oper-
ation or at least once a season) if the engine has to
operate under demanding conditions or if the am-
bient temperature is high.
Use oil according to the table below.
Use oil without any additives.
Oil SAE 10W-30
Service class SJ or higher
