Lubrication of gearbox
The gearbox is permanently lubricated at the factory, never
open the gearbox.
In order to add grease does as followed:
1. Remove the spark plug cover on the engine.
2. Place the pack of grease in a bucket of warm water.
This will make the consistency thinner, so it is
easier to add to the gear. Avoid cutting off too much
of the tip on the pack. It is important that the tip is
as pointed as possible.
3. When the gearbox is in horizontal position. Remove
the screw. Figure 11 a.
4. Add grease into the hole. Activate the clutch handle
and pull the recoil a few times (min 3). This will
disperse the grease in the gear.
5. Hereafter add more grease until grease comes out
of the hole
6. Fit and tighten the screw again.
7. Fit the spark plug cover on the engine.
Figure 11
Check grease level and add grease to the gear for every
5 operating hours. Extra grease is not included.
Starting and stopping the engine
Remember: Always check the oil level prior to use!
The oil level must always be between the min. and max.
Mark on the dipstick. Always use SAE-30 oil. Use only
unleaded 95 octane gas. Never over-fill the gas tank.
Warning: Stay out of dashed zone, while starting the engine!
Always start the engine from dotted operation zone See
Figure 7.
Starting the engine
1. Set the throttle control on the handle to max.
2. Position the choke at max. Move the choke lever fully to
the left. The choke is not required if the motor is hot.
3. Pull the start cord to start the motor. Always feed the
start cord back into the motor by hand.
4. When the motor is started, set the choke to minimum
(fully to the right) Engage the throttle slightly.
Stopping the engine
Set the throttle control to "low" and let the motor run for
1.
approx. 30 seconds.
2. When the motor idles, set the throttle control to full stop.
Vibrations may travel up into the handle during use. We
therefore recommend taking a break every 2 hours.
Cleaning the tiller
The tiller should be cleaned after use. Use a garden hose to
wash off soil and dirt. Remove any grass, etc. from the rotor
shaft. The chassis number should only be cleaned with a
damp cloth to avoid unnecessary wear. Avoid using a high-
pressure washer during cleaning.
Changing the oil
The oil should initially be changed after the first 5 hours of
use, and thereafter once per year.
1. Let the motor run for 5 minutes to heat up the oil.
This allows the oil to run more freely and makes for
a more complete oil change.
2. After 5 minutes, stop the motor. Remove the spark
plug cap. Drain the oil by unscrewing the sump plug.
Remember to drain the oil into a container of
sufficient capacity. NB: The motor must not be
tipped backwards more than 45 degrees.
3. Screw the sump plug back in and pour new oil into
the motor. Do this by removing the dipstick and
pouring in the recommended quantity of oil.
4. Refit the spark plug cap.
Alternatively, use an oil extractor kit.
1. Suck the oil up through the oil filler hole using the
syringe. Use the hose to reach the sump.
2. Transfer the used oil to the container.
3. Fill the engine with new SAE-30 oil.
4. Check the oil level using the dipstick.
Remember to dispose of used oil in a safe way.
Oil and oil extractor kit are not included
Air filter maintenance
Please inspect and clean the air filter on a regular basis. If
the filter has not been cleaned for a longer period, this will
have influence on the engines power take-off and the
exhaustion.
1. Clean around the air filter before it is removed.
2. Carefully remove the paper filter and check it. Brush
it with a soft brush. If it is very dirty, it must be
changed. Take care that no dirt gets into the intake
of the engine.
3. Wash the black foam element on the right side in
warm soapy water.
4. Press the water out of the foam element and let it
dry. Put a few drops of SAE-30 oil on the filter to
moisten it lightly with oil. Carefully squeeze out any
surplus oil. Remount the element.
5. Check that all parts are fitted correctly and the cover
closed as shown in the picture.
Spark plug maintenance
•
Remove the spark plug cap.
•
Brush away any dirt and deposit of the spark plug.
•
Loosen the spark plug using a spark plug socket.
•
Check the insulation is intact.
•
Clean the spark plug using a wire brush.
•
Measure the electrode gap 0.7–0.8 mm. Avoid
damaging the electrode. If it is damaged, replace it
with a new one.
•
Refit the spark plug.
•
Refit the spark plug cap.
