Safety regulations 1. Safety regulations 1.1 Correct use / General safety instructions The chainsaw must only be used to cut wood and objects made of wood. The chainsaw must not be used for any other purposes (chapter 10.1 "Application areas"). Before you start using the saw for the first time, please take the time to carefully read through these operating instructions, and make sure you keep them in a safe place.
Safety regulations 1.3 Fuelling • • • • • • • • • • • Petrol is very light and highly flammable. Keep away from open flames and never spill fuel. Do not smoke at the operating site or at and near the refuelling site! Stop the engine prior to refuelling. Let the engine cool down before refuelling - fire risk! Open the tank lid slowly to allow any excess pressure in the tank to be reduced without the risk of petrol spraying out. Fuel may contain substances similar to solvents.
Safety regulations 1.7 Starting the tool • • • • • When starting the tool, keep a minimum distance of 3 metres to where the tool was refuelled. Never start the device in an enclosed room. Make sure that you have a secure footing on firm ground when starting the tool. Always check that the ground is level and keep a safe hold of the power tool. Perform the start-up routine as described in chapter 8. "Starting the engine / stopping the engine". Once the unit has been started, check the idle setting.

Preparing the equipment for use ; Refuelling and adding oil to the chain lubrication system 5. Preparing the equipment for use 5.1 Assembly of the guide bar and chain The chain brake must be released when assembling the chain and adjusting the chain tension [pull back the hand protection (3) to the front handle (4)]. Notes for new saw chains: Before installing a new chain we recommend soaking it in a container (bowl) with chain oil with anti-fling additives that help the oil adhere to the chain. Fig.
Refuelling and adding oil to the chain lubrication system funnel with filter to prevent tank contamination. After filling the tank replace the tank lid and tighten firmly. Fig. 5 6.3 Chain lubrication Chainsaw oil with an anti-fling additive that helps the oil adhere to the chain should be used for lubrication of the saw chain and guide 6.
Chain brake ; Starting / Stopping the engine 7. Chain brake When the chain brake is activated, it stops the saw chain in a fraction of a second. Automatic engagement: In an emergency, the chain brake engages instantly in response to the inertia caused by kickback. Please note that even the highly effective automatic chain brake cannot offer complete protection against injury. Always work with great care and always avoid working situations which would put you at risk of kickback. Manual activation: Fig.
Starting / Stopping the engine 8.2 Starting up Please read the safety instructions before starting up the device. Fig. 8 • Always guide the starter handle back to its starting position – do not just let go and allow it to speed back by itself. A damaged starter cable can be replaced by a specialist. When the engine is running, lift up the power tool and hold it safely with both hands, then briefly operate the throttle control to cancel the part throttle setting. 8.
Hazards caused by kickback 9. Hazards caused by kickback When working with the chainsaw, careless or incorrect working methods can cause a dangerous situation which is referred to as "kickback". Kickback forces can occur when the running saw chain comes into contact with solid objects or if the saw chain suddenly gets stuck in the cut. In the process, the chainsaw is accelerated violently and uncontrollably.
Using the chainsaw ; Operating and maintenance information 10. Using the chainsaw Fig. 13 10.1 Application areas The chainsaw must only be used to cut wood and objects made of wood. Any loose wooden objects must be safely secured (e.g. on a sawhorse). When cutting down overgrown trees and branches please refer also to the notes on cutting down trees and removing branches. The chainsaw must not be used for any other purpose, for example to cut plastics or metals. 10.
Using the chainsaw Removing branches: Do not cut through free-hanging branches from underneath. Do not remove branches while standing on the trunk. Remove any obstructing branches before you start sawing. If you change your standing point, remember that the guide bar must always be on the side of the trunk facing away from your body.
Using the chainsaw ; Operating and maintenance information Making the felling notch: The felling notch determines the direction in which the tree falls and helps to control the fall. It is made perpendicular to the fall direction with a cut through 1/5 - 1/3 of the trunk diameter. The cut should preferably be made close to the ground. Fig. 15 c d e Start with the upper cut (roof of the felling notch). Then make the lower cut (bottom of the felling notch).
Operating and maintenance information 11.2 Maintenance and care of the cutting gear Saw chain: Just like any other cutting tool, the saw chain is subject to natural wear. Your chainsaw will only be able to deliver its full potential if the saw chain is correctly sharpened. Every saw chain is matched to the relevant chainsaw type in terms of its form, cutting performance and design. Only use the genuine SOLO saw chain which is approved for your chainsaw / guide bar type.
Operating and maintenance information • Important: Pull out the choke (7). Guide bar: The guide bar of your chainsaw requires just as much care as the saw chain. The running surfaces must be flat and level, and the groove must not be widened. In order to prevent one-sided wearing of the guide bar, we recommend that the guide bar be reversed whenever the chain is sharpened.
Operating and maintenance information 11.4 Carburettor settings 11.6 Maintenance of the chain brake The carburettor is preset to the optimum settings for the device at the factory. Depending on the particular location where the chainsaw is used (mountains, flat country) it may be necessary to adjust the idling settings via the idle stop screw "T" (24). When the idling settings are correct the engine should run smoothly at idle without the saw chain being driven.
