12.2.3.1 Tensioning the V-belt (13b)
1. Check the belt tension (thumb pressure). If the V-belt
(13b) gives more than 10-15 mm (thumb pressure), it
must be retightened.
2. Loosen the four nuts (13e) on the engine (6). Use a
13 mm open-ended spanner.

16 mm open-ended spanner.
4. Tighten the V-belt (13b) using the two adjusting
screws (13c) if the V-belt (13b) gives more than 10-15
mm (thumb pressure). Turn the adjusting screws (13c)
clockwise. Make sure that the engine (6) and pulley
remain at a right angle. Use a 16 mm open-ended
spanner.
5. After tensioning, retighten the four nuts (13e) on the
engine (6) and the counter nuts (13d). Use an 13 mm
open-end spanner and a 16 mm open-end spanner.
6. Put on the belt cover (13) and secure it with the two
screws (13a). Use a 13 mm open-ended spanner.
12.2.3.2 Replacing the V-belt (13b)
ATTENTION
When you remove or attach the V-belt, make sure that
your fingers do not get caught between the belt and the
pulley.
1. Loosen the four nuts (13e) on the engine (6). Use a
13 mm open-ended spanner.
2. To release the pre-tension of the V-belt (13b), loosen
the counter nuts (13d) and turn the two adjusting
screws (13c) anti-clockwise. Use a 16 mm open-end-
ed spanner
3. Push the engine (6) towards the eccentric vibration
unit (8).
4. Pull the worn V-belt (13b) off the pulleys and fit a new
V-belt (13b) correctly.
5. Tighten the V-belt (13b) using the two adjusting
screws (13c) if the V-belt (13b) gives more than 10-15
mm (thumb pressure). To do this, turn the adjusting
screws (13c) clockwise. Make sure that the engine (6)
and pulley remain at a right angle. Use a 16 mm
open-ended spanner.
6. After tensioning, retighten the four nuts (13e) and the
counter nuts (13d). Use a 13 mm open-ended span-
ner.
7. Put on the belt cover (13) and secure it with the two

Spilled oil can pollute the environment permanently.
The liquid is highly toxic and can quickly lead to water
pollution.
– Fill/empty oil only on level, paved surfaces.
– Use a filling nozzle or funnel.
– Collect drained oil in a suitable container.
– Wipe up spilled oil carefully immediately and dis-
pose of the cloth according to local regulations.
– Dispose of oil as per local regulations.
12.2.4.1
Check the oil level regularly before commissioning. An oil
level that is too low can damage the motor.
1. Start the motor as described in 10.1.
2. Allow the engine to warm up briefly.
3. Unscrew the oil dipstick (11).
4. Wipe the oil dipstick (11) with a clean, lint-free cloth.
5. Reinsert the oil dipstick (11) without screwing the oil
dipstick (11) back on.
6. Pull the oil dipstick (11) out and read the oil level in
the horizontal position. The oil level must be within the
mark on the oil dipstick (11).
7. If the oil level is too low, add the recommended
amount of engine oil as described in 6.
8. Then screw the oil dipstick (11) in again.
12.2.4.2
The engine oil affects the performance and service life of
the product.
Use an engine oil for 4-stroke engines.
SAE 10W-40 or SAE 15W-40 is recommended for gener-
al use.
The engine oil change should be carried out while the en-
gine is at operating temperature.
1. Provide a collection bucket to collect the used oil.
2. Remove the flexible hose (6a) from its holder to drain
the engine oil. Use a 13 mm open-ended spanner.
3. Unscrew the oil dipstick (11).
4. Wait until all the engine oil has drained into the collec-
tion bucket.
5. Fit the flexible hose (6a) back into the mounting brack-
et.
6. Fill the engine oil tank as described in 6.
7. Start the motor as described in 10.1.
