• Remove the air lter cover (Fig.19/Pos.A) by loosen-
ing the thumbscrew (Fig.19/Pos.B1)
• Loosen the thumb screw (Fig.20 / Pos.B2) and re-
move the air lter (Fig.20/Pos.14)
• Clean the air lter by tapping , replace if necessary.
• Reassemble in reverse order.
m WARNING
NEVER use gasoline or cleaning solvents with a low
ash point to clean the air lter element. A re or explo-
sion could result.
NOTE
Never run the engine without or with a damaged air
lter. Dirt gets so into the engine, causing serious engine
damage can occur. In this case, seller, and manufacturer
disassociate from any warranty.
Check, clean and replace spark plug (13) (Fig.11/15)
Check the spark plug (13) after 10 hours on dirt and
grime. If necessary, clean it with a copper wire brush.
Maintenance the spark plug after 50 hours of operation.
• Remove the spark plug ignition cable (25).
• Remove any dirt from the base of the spark plug (13).
• Use a wrench to remove the spark plug (13).
• Check the spark plug (13) visually. Remove any de-
bris with a wire brush.
• Look for discolouration on the top of the spark plug.
By default, the colour should be bright.
• Check the spark plug gap. An acceptable gap width
is 0.6 to 0.7 mm (see Fig.11).
• Remove the spark plug (13)carefully by hand.
• If the spark plug (13) has been inserted, tighten them
with a spark plug wrench.
• Attach the spark plug connector (25) at the spark
plug (13).
Note
Loosen spark plug can overheat and damage the en-
gine. And over tightening the spark plug can damage the
threads in the cylinder head.
Lubrication drive chain (Fig.9-10)
Remove cover (Fig.9 Pos.A) concerning the screws (19).
Regrease drive chain (24) every 500 operating hours.
Recap the opening with the lid (Fig.9 Pos.A) and the
screws (19) after servicing.
Disassembling wheels (Fig.6)
For maintenance disassemble the wheels as shown in
gure 6.
Cleaning
• Keep all safety devices, air vents and the motor
housing free of dirt and dust. Wipe the equipment
with a clean cloth or clean it with compressed air at
low pressure.
• We recommend that you clean your device after
each use.
Slacken off the locknut (27) and unscrew the adjusters
(26) to eliminate the play in the cable, which can occur
after initial use or normal wear. Be very careful not to
unscrew the adjusters (26) too much because this can
create another problem: the loss of traction. Remem-
ber to tighten the locknut (27) when you have nished.
Lubrication
The gearbox is pre-lubricated and sealed at the factory.
Oil changes
Changing the transmission oil
The oil must be replaced every 1000 hours with the en-
gine still warm. If necessary leave the engine running
for a short time.
• Place a suitable container with a minimum of 2 litre
capacity under the oil drain plug (see Fig.12 Pos.28).
• First, open the oil drain plug (28) and then the oil ller
neck (29) and leave the entire engine oil ow (Fig.13).
• Close the oil drain plug (28) again.
• ll 1,62 litres of clean transmission oil into the oil ller
neck (29). To do this, use a gear oil pump with hose.
Insert the hose through the opening in the oil ller
neck (see Fig.13).
Engine Oil
Check the oil level before each use. Remove the oil
dipstick (23) and check the machine in horizontal posi-
tion that the oil level is between the two marks. If nec-
essary, add oil.
Changing the engine oil
The oil must be replaced every 50 hours. For this the
motor must be warm and stopped. For this run engine
for a short time. Afterwards drain oil into a suitable con-
tainer. For this purpose remove the dipstick (Fig. 18
pos.23) and the oil drain plug (Fig. 18 pos.22). Maybe
take a suitable hose or tube to help. After the oil has
been completely drained mount the oil drain plug (22)
again, ll in new oil and close the oil ller cap (23).
Recommended engine oil
SAE 10W-30 or SAE 10W-40 (depending on applica-
tion temperature).
Dispose of waste oil properly at the local used oil col-
lection point. It is forbidden to discharge waste oil into
the ground or mixed with other waste.
Important hint in case of sending the equipment to
a service station:
In case of delivery, please note that the unit must be
free of oil and fuel to ensure safe shipment.
Air lter
Frequently cleaning of the air lter prevents carburetor
malfunction.
Clean the air lter and change air lter inserts
• The air lter (Fig.20/Pos.14) should be cleaned every
30 hours.
