5 Maintenance5.1 Introduction - maintenanceFor better operating reliability and longer service life:check and clean the robotic lawnmower regularly andreplace worn parts if necessary. All maintenance andservicing must be done according to Husqvarna'sinstructions. SeeGuarantee terms on page 59.When the robotic lawnmower is first used, the blade discand blades should be inspected once a week. If theamount of wear during this period has been low, theinspection interval can be increased.It is important that the blade disc rotates easily. Theedges of the blades should not be damaged. Thelifetime of the blades varies immensely and depends forinstance on:• Operating time and size of the working area.• Type of grass and seasonal growth.• Soil, sand and use of fertilizers.• The presence of objects such as, toys, tools, stones,roots and the like.The normal life is 3 to 6 weeks when used underfavorable conditions. SeeReplace the blades on page46 on how to replace the blades.WARNING: Wear protective gloves.Note: Working with blunt blades gives a poorer mowingresult. The grass is not cut cleanly and more energy isneeded, resulting in the robotic lawnmower not beingable to maintain such a large area.5.2 Clean the robotic lawnmowerIt is important to keep the robotic lawnmower clean. Amower with large amounts of grass stuck to it will notcope as well with slopes. It is recommended to cleanusing a brush.Husqvarna offers a special cleaning and maintenance kitas an accessory. Please, contact Husqvarna customerservice.CAUTION: Never use a high-pressure washerto clean the robotic lawnmower. Never usesolvents for cleaning.5.2.1 Chassis and blade disc1. Set the Main switch to position0.2. Lift the robotic lawnmower onto its side.3. Clean the blade disc and chassis using for examplea dish brush. At the same time, check that the bladedisc rotates freely in relation to the foot guard. Also,check that the blades are intact and can pivot freely.If long grass or other objects find their way in, thesemay impede the blade disc. Even a slight brakingeffect leads to a higher consumption of energy andat worst will prevent the robotic lawnmower frombeing able to mow a large lawn.5.2.2 ChassisClean the underside of the chassis. Brush or wipe with adamp cloth.5.2.3 WheelsClean around the front wheels and rear wheel as well asthe rear wheel bracket. Grass on the wheels can impacton how the lawnmower works in slopes.5.2.4 BodyUse a damp, soft sponge or cloth to clean the body. Ifthe body is very dirty it may be necessary to use a soapsolution or washing-up liquid.5.2.5 Charging stationClean the charging station regularly from grass, leaves,twigs and other objects that may impede docking.5.3 Replace the bladesWARNING: Always use blades and screws ofthe right type. Husqvarna can only guaranteesafety when using original blades. Onlyreplacing the blades and reusing the screw canresult in a screw wearing during mowing andshearing. The blades can then be propelledfrom under the body and cause serious injury.Replace worn or damaged parts for safety reasons.Even if the blades are intact, they should be replaced ona regular basis for the best mowing result and lowenergy usage.All 3 blades and screws must be replaced at the sametime to obtain a balanced cutting system.Use Husqvarna original blades embossed with thecrowned H-mark logotype, seeGuarantee terms onpage 59.46 - Maintenance 840 - 001 -
