2.7 Sharpening the mowing blade

If you do not have the necessary expertise
or auxiliary equipment, you should have
the blade sharpened by a specialist dealer
(VIKING recommends VIKING specialist
dealers). Operation of the machine is
impaired in the case of an incorrectly
sharpened mowing blade (incorrect
sharpening angle, imbalance, etc.).

Sharpening instructions

●

Remove the mowing blade. (

12.6)

●

Cool the mowing blade during
sharpening, e.g. with water.
The blade must not be allowed to
display blue colouring, as this would
reduce its cutting quality.

●

Sharpen blades evenly to prevent
vibration due to imbalance.

●

Observe a sharpening angle of

30°

●

Observe the wear limits (

12.5).

2.8 Storage (winter break)

Store the machine in a dry and locked
place that is generally free of dust. Make
sure that it is kept out of the reach of
children.

Only store the lawn mower in good
operating condition, fold down the
handlebar if necessary.

Keep all nuts, pins and bolts tightly
fastened, replace danger signs and
warnings on the machine that have

become illegible, check the entire machine
for wear and damage. Replace all worn or
damaged parts.

Any machine faults must be completely
remedied prior to storage.

Note the following points when storing the
lawn mower for long periods (winter
break):

●

Clean all external parts of the machine
with care.

●

Thoroughly lubricate/grease all moving
parts.

Carrying and securing lawn

mower

Carrying the machine:

●

Only lift the lawn mower by the
transport handles (1, 2). Always ensure
sufficient distance between the mowing
blade and your body, particularly your
feet and legs.

●

Carry the lawn mower using both
hands, with one hand at the upper
transport handle (2) and the other hand
at the lower transport handle (1),

●

carry the lawn mower with one hand at
the upper transport handle (2).

In order to prevent damage to the
blade fastening screw, use a
suitable socket (22 mm) for
loosening and tightening.

Risk of injury!

The mowing blade must only be
installed as shown, in particular
tabs (6) must face downwards.
Always replace blade fastening
screw (3) when replacing the
mowing blade. The specified torque
when tightening the blade fastening
screw must be strictly observed, as
the secure attachment of the cutting
tool depends on this.
