7.2 Maintenance
Please refer to the supplied petrol service
manual for information on the maintenance
intervals.
Note: Dispose of soiled maintenance material
and operating materials at the appropriate collec-
tion point.
7.2.1 Petrol engine
Note! Never run the engine with no or too little oil.
This can cause serious damage to the engine.
Checking the oil level
Place the lawn mower so that it stands level. Un-
screw the oil dipstick (Fig. 9a/Item 7) by turning
it counter-clockwise and wipe the dipstick. Re-
insert the dipstick into the fi ller opening as far as it
will go but do not screw it in. Pull out the dipstick,
hold it horizontally and read off the oil level. The
oil level must be between the two marks min. and
max. on the oil dipstick (Fig. 9b).
Changing the oil
The engine oil is best changed when the engine
has been switched off but is still warm.
1. Make sure that the debris bag has been re-
moved.
2. Empty the petrol tank with a petrol suction
pump and run the engine until the remaining
fuel is fully consumed.
3. Place an oil drip tray alongside the mower.
4. Open the oil fi ller plug (Item 7) and tilt the mo-
wer 90° sideways.
5. The hot oil will fl ow through the open oil fi ller
opening into the oil drip tray.
6. After the old oil has drained out, set the mo-
wer upright again.
7. Fill in engine oil up to the top mark on the oil
dip stick.
8. Important! Do not screw in the oil dipstick to
check the oil level – only insert it as far as the
thread.
9. Dispose of the used oil in accordance with
applicable regulations.
7.2.2 Blades
For safety reasons, have all blade sharpening,
balancing and mounting work carried out by an
authorized service center. To achieve optimal re-
sults, we recommend having the blades checked
once a year.
Changing the blades (Fig. 8)
When changing the cutting unit, be sure to use
only genuine replacement parts. The identifi cation
mark on the blade must correspond with the num-
Anl_GC_PM_46_S_HW_T_SPK9.indb 26
Anl_GC_PM_46_S_HW_T_SPK9.indb 26
GB
ber specifi ed in the spare parts list.
Never install a blade from a diff erent manufactu-
rer.
Damaged blades
If, in spite of all caution, the blade comes into con-
tact with an obstacle, switch off the engine imme-
diately and pull off the spark plug connector.
Tilt the lawn mower to the rear and check the
blade for damage. Damaged or bent blades must
be replaced. Never straighten a bent blade. Never
work with bent or heavily worn blades as this will
result in vibrations, causing further damage to the
mower.
Warning! Risk of injury when working with a da-
maged blade.
7.2.3 Axles and wheel hubs
Grease should be applied to the axles and wheel
hubs once per season.
To do so, remove the wheel caps with a screwdri-
ver and loosen the fastening screws on the
wheels.
7.2.4 Care and adjustment of the actuator
cables
Oil the actuator cables at regular intervals and
check that they move easily.
7.2.5 Maintenance of the air fi lter
(Fig. 10)
Soiled air fi lters reduce the engine output by sup-
plying too little air to the carburetor. If the air con-
tains a lot of dust, the air fi lter must be checked
more frequently.
Never clean the air fi lter with petrol or infl ammable
solvents. Clean the air fi lter only with compressed
air or by tapping it.
7.2.6 Maintenance of the spark plug
Clean the spark plug with a copper wire brush.
1. Pull off the spark plug connector (Fig. 11/Item
A).
2. Remove the spark plug using a spark plug
wrench.
3. Assemble in reverse order.
7.2.7 Inspecting the V-belt
Remove the blade as described in 7.2.2.
To inspect the V-belt you must remove the V-belt
cover (Fig. 12/Item 5b).
7.2.8 Repairs
After carrying out any repair or maintenance
work, ensure that all safety parts are installed and
