Initial operation Notes on mowing Mowing on slopes For safety reasons, VIKING mowers with petrol engines must not be used on slopes with an incline of more than 25° (46.6 %). It is only permitted to mow across the direction of the gradient and never up or down the slope, in order to prevent loss of control of the lawn mower. Risk of injury! A slope inclination of 25° corresponds to a vertical height increase of 46.6 cm for a 100 cm horizontal surface.In order to ensure an adequate oil supply for the engine, the information in the accompanying engine instruction manual must be additionally observed when using the machine on slopes.

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 (specialist). Do not mow wet grass or mow in the rain. For safety reasons, always use an undamaged grass catcher bag. CAUTION

• Carefully inspect the complete area on which the appliance is to be used and remove any stones, sticks, wires, bones and other foreign objects. I= First, push front axle height adjustment lever and K= rear axle height adjust - ment lever in direction of the wheel and then allow to engage in the desired position (= cutting height). The cutting height indicators are located immediately next to the adjustment levers, on the housing or on the grass catcher bag. NOTE The cutting height settings on the front and rear axles should be identical. Different cutting heights result in a reduced collecting performance.8 0478 111 9912 I - EN B= Actuate and hold the motorstop lever on the upper handlebar. C= Pull out the starter cable slowly to the point of resistance and then pull vigorously to arm's length. Slowly release the cable so that it can gra dually be rolled up by the starter. Repeat until the engine starts. NOTE Do not start the engine in high grass or when the mower is set to the lowest cutting height, as otherwise the engine will be difficult to start. NOTE Thanks to a fixed throttle adjustment, the engine always operates at the optimum working speed. Starting the engine MB 443, MB 443 T, MB 443 X, MB 448 TX When starting a cold engine, first press the primer 21= three times. When starting a warm engine, it is not normally necessary to actuate the primer. In cold weather, however, it may be necessary to actuate the primer again (three times) when re-starting the engine. The primer must also be actuated three times when restarting after running empty and after refilling the tank.

• Re-filling with petrol must be performed before the engine is started. When the engine is running or is hot, the tank cap must not be removed and the tank must not be re-filled with petrol.

• Start the engine with care. Ensure that you keep your feet far enough away from the cutting tool.

• Risk of injury. Never put your hands or feet on or underneath cutting deck.

• Always wear robust shoes and long trousers when mowing. Never mow barefoot or in sandals.

• Never mow in the vicinity of other persons, particularly children, or animals. Stopping the engine Switching off the engine B= Release motorstop lever. The engine and blade come to a standstill following a brief run- down time.

Sharpening the mowing blade 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. Sharpening the mowing blades

The ball bearings of the wheels are maintenance-free. The gearbox is maintenance- free. Wheels and wheel drive

Mowing blade maintenance 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 (27), retaining washer (29) when replacing the mowing blade. 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. Maintenance interval: Before each use Tilt the mower upwards into the cleaning position. 26= 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 33= 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.11 0478 111 9912 I - EN DEENFRNL

Installing the mowing blade Install the mowing blade with the curved edges pointing upwards. For installation, 25= use a wooden block (approx. 60 x 60 mm) to counterhold the 26= mowing blade. 28= Fit the mowing blade onto the blade mount and 27= tighten the blade fastening screw with 29= retaining washer to a torque of 60 - 65 Nm.
