Safety regulations
- 27 - ENGLISH 5
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. Prevent products made from mineral oil coming into
contact with skin and eyes. Wear protective gloves during filling with fuel. Frequently change and clean
protective clothing.
• Avoid breathing in fuel vapour.
• The refuelling site should be well ventilated.
• Avoid any soil spillage of fuel or oil (protection of the environment). Use a suitable mat.
• Immediately clean any spilled fuel on the machine. Change contaminated clothing without delay.
• Always tighten the fuel tank cap firmly by hand without using any tools. The fuel tank cap must not be able
to work itself loose as a result of the vibrations of the engine.
• Check for petrol leaks. Do not start the machine or work with the machine if there is a petrol leak. Life
threatening risk from burns!
• Store fuel and oil in approved and correctly labelled containers.
1.4 When transporting the equipment
• When carrying the chainsaw for short distances (from one working area to the next), always apply the chain
brake so that the chainsaw is blocked (preferably switch the engine off as well).
• Never carry or transport the power tool while the cutting tool is running.
• When transporting the device over longer distances, always switch the engine off and attach the chain
guard.
• To prevent leakage of fuel or oil and damage in general, make sure that the device is secured so that it
cannot fall over when it is transported in vehicles. Check the fuel and chain lubrication tanks for leaks.
Ideally you should drain the tanks prior to transport.
• Always empty the tanks before dispatching the unit.
1.5 Notes on assembly, cleaning, adjustment, maintenance and repairs
• The power tool must not be assembled, maintained, repaired or stored in the vicinity of naked flames.
• The engine must be switched off and the stop switch set to "0“ for the duration of all work performed on the
guide bar and saw chain (for assembly, cleaning, maintenance and repairs) (ideally the spark plug
connector should be unplugged as well). Always use protective gloves.
• The power tool requires regular maintenance. Only perform maintenance or repairs yourself if the relevant
operations are covered in the operating instructions. All other work should be performed by an authorised
specialist workshop.
• During maintenance of the silencer or when checking that the silencer is firmly positioned, never touch the
silencer if it is still hot – risk of burns! The silencer gives off extremely large amounts of heat.
• Only genuine replacement parts supplied by the manufacturer must be used for any repairs.
• No changes must be made to the power tool, as this could affect the safety of the device and increase the
risk of accident or injury.
1.6 Before starting the tool
Check the tool every time before starting it to make sure that the complete power tool is operationally safe. The
following points should be checked in addition to the points listed in the operating and maintenance
instructions (chapter 11):
• The stop switch must be easy to switch.
• The throttle control must move freely and return automatically to the idle position. If the throttle control is
operated while the choke lever is pressed in then this must cancel any part throttle stop that is set.
• The guide bar must be firmly secured. Always check that the chain has the correct tension and adjust the
tension if required before starting the tool.
• Also check that the ignition cable and spark plug connector are firmly in place. If there is a loose connection
this can result is sparks which could ignite any escaping fuel/air mixture – fire hazard!
If anything is not as it should be, signs of damage are evident, settings are incorrect or the functional integrity of
the unit is compromised, do not start up the power tool. Instead, have it checked by a specialist workshop.
Safety regulations
ENGLISH 6 - 28 -.
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. The cutting blade must be stationary during idling.
• Once it has warmed up, switch the engine off and recheck the chain tension and adjust as required.
1.8 When working with the saw
• The power tool must only be started up if it is fully assembled.
• Work on windfall must only be performed by trained persons.
As soon as the engine is running, it produces toxic exhaust gases which may be colourless and
odourless. Never start up the tool in enclosed spaces. Always make sure that there is sufficient air
exchange if you are working under restricted conditions, such as in a dip or a ditch.
Do not smoke at the place of work or in the close vicinity of the power tool, as this would be an increased
fire hazard.
• Work carefully, deliberately and calmly and do not endanger the safety of others.
- Make sure that visibility and lighting conditions are good.
- Stay within calling distance of others who could help in the event of an emergency.
- Take breaks in good time.
- Be aware of potential sources of danger and take appropriate precautionary measures. Remember that
the use of ear defenders makes it more difficult to hear other sounds. This may also mask sounds
warning of imminent danger or shouts of warning etc.
- Remember that freshly debarked wood is very slippery (bark). Also take care in the wet, when the ground
is slippery, on slopes on uneven terrain.
- Look out for obstacles and hazards that could trip you up, e.g. tree roots, tree stumps and edges. Take
special care when working on slopes. Never work while standing on unstable ground.
- Always hold the power tool firmly with both hands and make sure you have a secure footing on stable
ground at all times.
- Never use the saw above shoulder height and avoid leaning too far forward. Never use the saw while
standing on a ladder, and never climb the tree holding the saw. The only safe way to reach greater
heights is to use a hydraulic lifting cabin.
- Move the chainsaw in such a way that no part of your body would be in the way if the arc of movement of
the saw chain was extended.
- Never touch the ground with the chainsaw while it is running.
- Do not use the saw to prise off or scoop away pieces of wood or other objects.
- Longitudinal cuts should be made at as flat an angle as possible. Special care is required here, as the
bumper spikes cannot engage.
- Be careful when cutting wood which has splintered, as sawn off pieces of wood can be torn off and fly off
at high speeds (risk of injury).
• Switch the engine off if you notice any significant changes in the behaviour of the power tool.
• Never touch the silencer while it is hot – risk of burns. Never set down the hot power tool in dried grass
or on other flammable objects. The silencer gives off extremely large amounts of heat (fire hazard).
• Never work with a defective silencer or without a silencer. You risk damaging your hearing and burning
yourself on the device.
First Aid
A first aid box should always be available on-site. Immediately replace any materials you have used:
Note:
Over exposing persons with circulatory problems to vibrations can lead to damage to their nervous system or
blood vessels. The following systems may occur from vibrations to fingers, hands or the wrists: Numbness,
itching, pain, twinges, changes to the colour of the skin or the skin itself. Seek medical advice if you experience
any of these symptoms.
