supervised by a person

responsible for their safety

or having received

instructions on use of the

appliance from such person.

Children must be

supervised, in order to

ensure that they do not play

with the appliance.

for shredding and chopping

tree and hedge cuttings,

for levelling earth mounds, e.g.

mole hills

or for transporting cuttings

(except in the grass catcher

bag provided).

Preparatory measures

- Always wear

robust shoes

and long

trousers when mowing.

Never mow barefoot or in

sandals.

- Carefully inspect the

complete area on which

the appliance is to be used

and remove any stones,

sticks, wires, bones and

other foreign objects which

could be thrown up by the

appliance.

- Before using the appliance,

always ensure that the

cutting tool, the fastening

bolts and the entire cutting

unit are in good condition.

- Caution!

Danger of

”playing” with the on/off

switch. Risk of motor

overheating.

- Owing to the voltage

fluctuations caused by this

appliance during the run-

up period, other devices

connected to the same

circuit may be subject to

interference in the case of

unfavourable power supply

conditions. In this case,

appropriate steps should

be taken (e.g. connection

to a different circuit than

the one used by the

affected device, or

operation of the appliance

using a circuit with a lower

impedance).

- Never attach any objects to

the handlebar (e.g. work

clothing). Extension cables

must never be wrapped

around the handlebar.

Notes on mowing

NOTE

To ensure a perfect, thick

lawn, mow regularly and keep

the grass short.

Do not cut too short in hot,

dry conditions as the lawn will

dry out or burn in the sun and

become unsightly.

The cutting pattern will be

better with a sharp blade than

with a blunt one. The blade

must therefore be sharpened

regularly (VIKING dealer).

CAUTION

Risk of injury!

Untangle any knots in the

cord immediately.

If using a cable drum, the

connection cord must be

unwound completely,

otherwise electrical

resistance may cause loss

of power and overheating.

This can be read off the

Mowing on slopes

For safety reasons, the lawn

mower must not be used on

inclines of more than 25°.

A slope inclination of 25°

(46.6 %) corresponds to a

vertical height increase of

46.6 cm for a 100 cm

horizontal distance.

Correct motor load

Do not switch on the mower

in tall grass or at the lowest

cutting height.

The lawn mower load must

never cause the motor speed

to drop significantly.

If the speed drops, select a

higher cutting height setting

and/or reduce the rate of

feed.

Thermal motor

overload protection

If an overload of the motor

occurs during operation, the

built-in thermal overload

protection device

automatically deactivates the

motor.

Causes for an overload:

10

Guide the connection cord

behind you when mowing.

Connection cords can be

inadvertently cut when

mowing and therefore

involve a high accident risk.

For this reason, mow so

that the connection cord is

always visible in the area of

grass that has already been

cut.

Strain relief

During mowing work, the

strain relief prevents any

unintentional disconnection of

the connection cord and

resulting possible damage to

the mains connection on the

appliance.

For this reason, the

connection cord must be fed

through the strain relief.

Form a loop with the

10= connection cord and

guide it through the

11= opening.

Pass the loop over the

12= hook and tighten.

CAUTION

Risk of injury!

If you do not have the

necessary expertise or

auxiliary equipment, please

always contact a specialist

dealer. (VIKING

recommends VIKING

specialist dealers).

VIKING recommends the

use of original VIKING

spare parts.

Risk of injury!

Always wear

standstill.

If you do not have the

necessary expertise or

auxiliary equipment, please

always contact a specialist

dealer.

VIKING recommends that you

have maintenance operations

and repairs performed

exclusively by a VIKING

specialist dealer.

VIKING recommends the use

of original VIKING tools,

accessories and spare parts.

Maintenance interval:

Each time the appliance is

used

Clean the appliance

thoroughly each time it has

been used. Care of the

appliance will protect it

against damage and extend

its service life.

Cleaning the appliance

17

Remove dirt from the cooling

air guide (inlet slots) between

the motor cover and the lower

housing to ensure that the

motor is adequately cooled.

Clean the mowing blade.

Clean the underside of the

mower with water and a

brush. Detach accumulated

cutting deposits in the

housing and in the ejection

chute beforehand using a

stick.

Never spray water onto

motor components, seals,

bearing points or electrical

parts such as switches. This

would result in expensive

repairs.

Do not use aggressive

cleaning agents. These

cleaners can damage plastics

and metals, impairing safe

operation of your VIKING

mower.

If you are unable to remove

the dirt with water, using a

brush or a cloth, VIKING

recommends the use of a

special cleaner (e.g. STIHL

special cleaner).

For removal, use a

16= wooden block (approx.

60 x 60 mm) to

counterhold the

17= mowing blade.

Unscrew the

18= blade fastening screw

using an A/F 24 spanner.

Remove the

17= mowing blade.

Risk of injury!

Always wear

gloves.

CAUTION

Risk of injury!

Check blade for damage

before installing.

The blade must be replaced

if notches or cracks are

identified, if the blades are

worn back by 5 mm, or if

the blade is thinner than

2 mm at any point (wear

limits).

The sharpening angle of the

blade is 30°.

The following points must be

observed when re-sharpening

the mowing blade:

• Cool the mowing blade

when 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.

19

Sharpening the

mowing blade

19

Removing the mowing

blade

Guide the

19= screwdriver through the

20= central bore of the

17= mowing blade and align

the blade horizontally.

If the mowing blade is

properly balanced it will

remain in this horizontal

position.

• If the blade leans to one

side, re-sharpen this side

until the blade is evenly

balanced.

20

Checking the balance

of the mowing blade

CAUTION

Risk of injury!

A worn blade may break off

and cause serious injuries.

The instructions for blade

maintenance must therefore

always be observed.

Blades are subjected to

differing degrees of wear

depending on the location

and duration of use. If you

use the mower on sandy

ground or use it frequently

under dry conditions, the

blade will be subjected to

greater loads and will wear

more quickly than the

average.

Always replace the blade

fastening screw (18) when

replacing the mowing blade.

Maintenance interval:

Before each use

Tilt the mower upwards into

the cleaning position.

• Clean the mowing blade

and check it for damage

(notches or cracks) and

wear; replace if necessary.

Wear limits:

The blade thickness must be

at least 2mmat any point.

(Check using slide calliper).

The blades may not be

ground back by more than

5mmduring sharpening.

When inspecting, place a

22= ruler against the front

blade edge and check for

wear.

CAUTION

If the supplied standard

blade is not installed in the

lawn mower, but e.g. the

mulching blade, which is

available as a special

accessory, different wear

limits apply.

0478 121 9909 E - EN

The adjustment must be

repeated (if necessary,

contact a specialist dealer;

VIKING recommends VIKING

specialist dealers).

CAUTION

Risk of injury!

If, when pulling back, the

driving wheels are locked

when the drive lever is not

actuated, the cable is

adjusted incorrectly and the

mower drive is permanently

activated.

As a result, the mower may

start to move unintentionally

immediately when started

and this may result in injury

or damage to the appliance.

Maintenance interval:

As required (wheel drive

does not engage when the

wheel drive lever is

actuated)

The tension of the cable is

adjusted correctly at the

factory. However, the cable

may have to be adjusted

again following an extended

period of use.

The adjustment is made

via an

21= adjustment screw located

on the left of the upper

handlebar.

22

Adjusting the wheel

drive cable

The cable tension is

increased by turning the

21= adjustment screw in the

“+” direction, turning it in

the “-” direction reduces

the tension.

Correct adjustment:

Actuate the drive lever while

pulling the lawn mower

backwards.

The driving wheels must lock

after approx. one third of the

lever travel.

Storage

(winter break)

The storage room should be

dry and free of dust. The

mower should also be stored

out of reach of children.

Any appliance faults must be

remedied prior to storage in

order to maintain a safe

operating condition.

Note the following points

when storing the mower for

long periods (winter break):

- Carefully clean all external

parts of the appliance.

- Thoroughly

lubricate/grease all moving

parts.

CAUTION

Risk of injury!

Observe the specified

torque of 10 - 15 Nm when

tightening the blade

fastening screws, as the

secure attachment of the

cutting tool depends on this.

Additionally secure the

blade fastening screw (18)

with Loctite 243.

Install the

17= mowing blade with the

curved wings pointing

upwards.

For installation, use a

16= wooden block (approx.

60 x 60 mm) to

counterhold the mowing

blade.

Tighten the

18= blade fastening screw to

a torque of 10 - 15 Nm.
