The switch and safety devices installed in the machine must not be removed or bypassed. In particular, never secure the motorstop lever to the handlebar (e.g. by tying it). Caution – risk of injury! Never put hands or feet on or underneath rotating parts. Never touch the rotating blade. Always keep away from the discharge opening. Always observe the safety distance provided by the handlebar. The handlebar must always be installed correctly and must not be modified. Never operate the machine with the handlebar folded down. Never attach any objects to the handlebar (e.g. work clothing). Only work during the day or with good artificial light. Do not work at ambient temperatures below +5°C (41°F). Do not operate the machine in the rain or during thunder storms, particularly when there is a risk of lightning strike. The risk of accidents is higher if the ground is damp due to increased danger of slipping. Particular caution should be exercised during working in order to prevent slipping. If possible, avoid using the machine when the ground is damp. Do not leave the machine in the rain. Switching on the machine: Exercise care when switching on the machine and observe the instructions in the section "Initial operation of the machine". (Ö 12.) Keep your feet a safe distance from the cutting tool. Place the machine on an even surface before switching it on. The machine must not be tilted before it is switched on or during switching-on. Do not switch on the motor if the discharge chute is not covered by the discharge flap or the grass catcher box. Avoid switching the machine on repeatedly within a short period of time; in particular avoid "playing" with the ON button. Risk of motor overheating. Working on slopes: Always work across and back on slopes, never up and down. If the user loses control when mowing up and down, there is a risk of being run over by the machine. Be particularly careful when changing direction on a slope. Always ensure good stability on slopes and avoid mowing on excessively steep slopes. For safety reasons, the machine must not be used on slopes with an inclination of more than 25° (46.6%). Risk of injury!

The flow of air that is created by the rotary movement of the mowing blade and is responsible for filling the grass catcher box raises the level indicator (2): The grass catcher box is filled with clippings. When the grass catcher box is full, this flow of air is reduced and the level indicator drops (3): ● Empty filled grass catcher box (Ö 12.4).

To ensure a perfect, thick lawn, mow regularly and keep the grass short. Do not cut the lawn too short in hot, dry conditions as it 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 should therefore be sharpened regularly (VIKING specialist dealer). Cutting performance The cutting performance (battery running time) depends on the properties of the grass and the selected cutting height. The cutting performance is enhanced by the following measures: ● Mow the lawn more frequently ● Increase the cutting height ● Reduce speed of propulsion ● Allow the lawn to dry before mowing. If required, additional STIHL lithium-ion batteries can be purchased (special accessories).

10.2 Working area for operator

● For safety reasons, the operator must stay within the working area behind the handlebar when the motor is running. Always observe the safety distance provided by the handlebar. ● The lawn mower must only be operated by one person. Other persons must keep out of the danger area. (Ö 4.)

10.3 Correct motor load

Do not switch on the lawn mower in tall grass. Select a higher cutting height setting if the motor is difficult to start. 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.

10.4 If the mowing blade blocks

Switch off the motor immediately and disconnect the safety plug. Then eliminate the cause of the fault.

10.5 Thermal motor overload

protection The electronics switch off the motor if it becomes overloaded during operation. Three red LEDs in the battery light up if a thermal overload occurs. (Ö 8.5) Causes for an overload: – mowing excessively high grass or cutting height adjusted too low, – excessive rate of feed, – inadequate cleaning of the cooling air guide (inlet slots). Recommencing operation Resume normal operation of the machine following a cooling period of up to 10 min. (depending on the ambient temperature) (Ö 12.2). The machine is equipped with several safety devices for safe operation and for the prevention of improper use.

10. Notes on working with

Risk of injury! If a safety device is found to be defective, the machine must not be operated. Consult a specialist dealer; VIKING recommends VIKING specialist dealers.0478 131 9922 D - EN

The lawn mower is equipped with safety devices, which prevent inadvertent contact with the mowing blade and with ejected clippings. These include the housing, discharge flap, grass catcher box and correctly installed handlebar.

11.3 Two-hand operation

The motor can only be switched on by pressing and holding the ON button with the right hand and then pulling the motorstop lever to the handlebar with the left hand.

11.4 Motor run-down brake

When the motorstop lever is released, the mowing blade comes to a complete standstill in less than three seconds. An integrated motor run-down brake shortens the run-down time until the blade stops. Measuring run-down time Following motor start-up, the blade rotates and a wind noise is audible. The run-down time corresponds to the duration of the wind noise after the motor stops. This can be measured using a stopwatch.

12.2 Switching on lawn mower

● Press and hold down ON button (1). Pull motorstop lever (2) to handlebar and hold. ● The ON button (1) can be released once motorstop lever (2) is pressed.

12.3 Switching off lawn mower

● Release motorstop lever (1). Motor and mowing blade come to a stop after a short run-down time.

12.4 Emptying the grass catcher

box ● Detach the grass catcher box. (Ö 9.5) ● Open the grass catcher box at the tab (1). Fold up the upper part of the grass catcher box (2) and hold. Fold the grass catcher box rearwards and empty the clippings. ● Close the grass catcher box. ● Attach the grass catcher box. (Ö 9.5)

13.6 Checking blade wear

Maintenance interval: Before each use ● Tilt the mower upwards into the cleaning position. (Ö 13.2) ● Clean the mowing blade (1). ● Place a ruler (1) against the front blade edge and measure permissible grinding A. ● Measure blade width B using a slide calliper (2). ● Check blade thickness C at 5 points at least using a slide calliper (2). In particular, minimum thickness must also be ensured in the area of the blade wings. Wear limits: Permissible grinding A: < 15mm Blade width B: > 39 mm Blade thickness C: > 1,6 mm The blade must be replaced, – if it is damaged (notches, cracks), Risk of injury! Before tipping up the mower, place it on firm, level and flat ground. The machine may tip over when working on it in the cleaning position. Always stand to the side of the machine. Never work in front of or behind the mower. Risk of injury! Blades are subjected to differing degrees of wear depending on the location and duration of use. If you use the machine 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. A worn blade may break off and cause serious injuries. The instructions for blade maintenance must therefore always be observed. 230478 131 9922 D - EN

– if the measured values are achieved at one or more points or are outside the permissible limits. If the multi-blade available as a special accessory is installed on the lawn mower, different wear limits apply (see instruction manual for accessory).
