2. Safety regulations
2.1 Correct use
The chainsaw must only be used to cut wood or wooden objects. It must only be used in the working
situations described in Chapter 7, "Using the chainsaw".
Loose cutting objects must be safely secured (e.g. on a sawhorse). When cutting down overgrown
trees and branches, please refer to the notes on cutting down trees and removing branches in
Chapter 7, "Using the chainsaw".
The chainsaw must not be used for any other purpose, for example to cut plastics or metals.
2.2 General safety instructions
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. At all times the instructions
must be kept available at the place where the saw is being used. The instructions must be read by
anybody who works with or on the device (including for maintenance, care and repairs).
Take special care when using this power tool. By handling the power tool recklessly or without the
necessary care and attention you can put yourself in grave danger. These are based:
• Firstly on the characteristics of the power tool, such as:
- The high speed of the saw chain, the sharpness of the cutting teeth and the magnitude of
the forces and torques that can be developed by the power tool,
• and secondly on the hazards arising from the object being cut when work progresses very quickly,
- particularly when working in a forest or on cutting objects which are under stress.
Always work with the utmost care and constantly remind yourself of the potential dangers and
hazards that could occur. Never undertake any work you are not fully comfortable with or if you are
not in a position to fully assess the risks involved. If you are still unsure after reading these operating
instructions, please consult a specialist or enrol in a training course for safe handling and use of the

2.4 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.
2.5 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). Carry
the chainsaw by the front handle. The guide rail of the chainsaw should point backwards. Avoid
touching the muffler (risk of being burned).
• Never carry or transport the power tool while the cutting tool is running.
When transporting the equipment over longer distances, transporting it in vehicles or shipping
it, 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.
Recommendation: Please keep the original packaging in order to protect the equipment against
transport damage in case you ever need to ship it or transport it.
Safety regulations - During assembly, cleaning, maintenance and repair, Before starting the tool
ENGLISH 9
E
N
G
2.6 During assembly, cleaning, maintenance and repair
• 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 "Stop“ 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.
2.7 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 8):
• 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 - Starting the tool, When working with the saw
ENGLISH 10

2.8 Starting the tool
•
The power tool must only be started up if it is fully assembled.
• 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 5. "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.
2.9 When working with the saw
The following safety rules must also be followed in addition to those already listed:
• Check the operation of the chain brake every time before you start work (see Chapter 3.9, "Chain
brake").
• 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.
Safety regulations - When working with the saw
ENGLISH 11
E
N
G
- 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 still 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.
