Maintenance Of The Spark Plug; Preparing The Mower For Long-Term Storage - EINHELL BM 46-S Montage- Und Bedienungsanleitung

Anleitung BM 46_S_SPK1:_
Use only engine oil (15W40).
Place the mower on a work table with the right-
hand front wheel (in the pushing direction)
projecting free of the table.
Place a flat oil drip tray beneath the mower.
Open the oil filler screw (Fig. 15/Item A).
Open the oil drainage screw (Fig. 17). Drain the
warm engine oil into a drip tray.
Close the drain screw again when all the used oil
has been drained.
Fill up with engine oil as far as the top mark on the
dipstick (approx. 0.6 l).
Important! Do not screw in the oil dipstick to check
the oil level – only insert it as far as the thread.
Dispose of the used oil in accordance with
applicable regulations.
12.5. Care and adjustment of the cables
Oil the cables at regular intervals and check that they
move easily.
Check the adjustment of the cables every time
before you use the machine.
12.5.1 Adjusting the cord for the engine brake
If you notice a drop in the performance of the
engine brake, the cord (Fig. 18/Item A) will need
readjusting.
12.5.2 Drive unit cable adjustment (Fig. 19)
In the drive position of the clutch lever (Fig. 13), the
clutch lever (Fig. 1/Item 1) should be pulled up to the
top push bar. If the cable is too taut, it must be set to
a longer length. To do this, undo the lock nut (Fig.
19/Item A) opposite the main cable (Fig. 19/Item B),
extend the screw connection and then tighten the
lock nut again. If the power of the drive unit starts to
fall, the clutch tension must be increased using the
cable. To do this, the screw connection must be
reduced (using the method described above). Set the
clutch lever (Fig. 1/Item 1) so that it can just touch
the top push bar.
12.6. Maintenance of the air filter (Fig. 20/21)
A soiled air filter will reduce the performance of the
engine because it will prevent enough air getting to
the carburetor. It is therefore imperative that regular
checks are made. The air filter should be checked
every 25 hours and cleaned if required. If the air is
very dusty the air filter should be checked more
regularly.
Important: Never clean the air filter with petrol or
inflammable cleaning agents. Clean the air filter with
compressed air or simply by knocking out any
soiling.

12.7. Maintenance of the spark plug

Check the spark plug for dirt and grime after 10
hours of operation and if necessary clean it with a
copper wire brush. Thereafter service the spark
plug after every 50 hours of operation.
Pull off the spark plug boot (Fig. 22) with a twist.
Remove the spark plug (Fig. 23) with the supplied
spark plug wrench.
Assemble in reverse order.
12.8. Tensioning the V-belt for the
travel drive (Fig. 24).
Check the tension of the V-belt for the travel drive at
regular intervals and re-tension it if required. To do
so, set the mower to the top cutting height. Slacken
the lock nut (Fig. 24/Item A) and adjust the tension of
the V-belt using the setting screw (Fig. 24/Item B).
Retighten the lock nut once you have completed the
readjustment work.
Tip: Adjust the setting screw by just 1 - 2 turns and
then give the mower a test run before adjusting by
the same amount again, if required, in order to avoid
the risk of tightening the V-belt by too much.
12. 9. Repairs
After any repair or maintenance work, check that all
safety-related parts are in place and in proper
working order.
All parts which may cause injury must be kept where
they are inaccessible to children or others.
Important: In accordance with product liability
legislation we are not liable for any damages caused
by improper repairs or the use of spare parts that are
not original spare parts or parts approved by us. In
addition, we are also not liable for any damages
arising from improper repairs. Such work should be
performed by a customer services workshop or
authorized specialist. The same applies to accessory
parts.
12.10. Times of use
Lawn mowers are only permitted to be used on
workdays between the hours of 7.00 a.m. and 7.00
p.m. Please comply with statutory regulations, which
may vary from location to location.
13. Preparing the mower for long-term
storage
Caution: Do not empty the petrol tank in enclosed
areas, near fire or when smoking. Petrol fumes can
cause explosions and fire.
