power cutter.)

WARNING! Never use a power cutter with

!

defective safety equipment. Follow the control, maintenance and service instructions described in this manual.

1 Anti-vibration system

Your power cutter is equipped with an anti-vibration system. This is designed to give as low vibration levels and comfortable usage as possible.

“What is

• HEAVY-DUTY, FIRM GRIP PROTECTIVE GLOVES

• SNUG-FITTING, HEAVY­DUTY, COMFORTABLE CLOTHING THAT ALLOWS FULL FREEDOM OF MOVEMENT

(Filling/Fuel mixture/Storage)

WARNING! Exercise great care when handling

!

• Never fill the machine while the engine is running.

• Provide good ventilation when filling or mixing fuel (gasoline and 2-stroke oil).

• Move the machine at least 3 m from the filling position before starting.

• Never start the machine:

• Store the power cutter and fuel so that any leakage or fumes

do not risk coming into contact with sparks or naked flames. For example, electric machines, electric motors, electrical switches/power switches, heaters or the like.

• When storing fuel, approved containers intended for this purpose must be used.

• When storing the power cutter for long periods the fuel tank must be emptied. Contact your local fuel station to find out how to dispose of excess fuel.

• Use a Partner fuel can with an anti-spill device.

a) If you have spilt fuel on it. Wipe up all spillage.

b) If you have spilt fuel on yourself or your clothes. Change your clothes.

c) If there is a fuel leak. Make regular checks for leakage from the fuel cap and the fuel supply pipes.

GENERAL WORKING INSTRUCTIONS

This section takes up the basic safety precautions for working with the power cutter. Follow these general working instructions, but never use a machine without the possibility of calling for help in the event of an accident.

Basic safety precautions

IMPORTANT INFORMATION! Never work with a power cutter that is defective or incorrectly adjusted. Do not work with a power cutter that is incomplete or where assembly has not been carried out in a satisfactory manner. Check that the cutting blade stops rotating when the throttle is released. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Avoid all usage which you consider to be beyond your capability.

• Check that no one is in the immediate vicinity when the machine is started or while working with the machine to ensure that people, animals or other things cannot affect your control of the power cutter.

• Avoid usage in unfavourable weather conditions, for example, thick fog, heavy rain, strong winds or extreme cold, etc. To work in bad weather conditions is tiring and can create dangerous circumstances, e.g. slippery surfaces.

• Never start to work with the power cutter before the working area is clear and you have a firm foothold. Look out for any obstacles with unexpected movement. Ensure when cutting that no material can become loose and fall, causing operating injury.Take great care when working on sloping ground.

• Make sure clothing and parts of the body do not come into contact with the cutting blade when the engine is started.

• Maintain a safe distance from the cutting blade when the engine is running.

• The blade guard should always be fitted when the engine is running.

• Ensure that the working area is sufficiently illuminated to create a safe working environment.

• Some working positions may create greater stress on the operator.

• Check the cutting area for buried cables and wires.

!

WARNING! Use a Partner fuel can with an anti-spill device. Fuel and fuel fumes are highly flammable. Think of the risks of fire, explosion and breathing in fumes. Stop the engine before refuelling. Do not overfill with fuel. Mop up any spills on the ground or the machine. If you spill fuel on yourself or your clothes, change your clothes. Move the machine at least 3 metres from the refuelling site before starting.

Only use the machine in areas with good

!

ventilation. Neglect can result in serious injury or death.

Cutting

WARNING! A safe distance from the power

• Start cutting with the engine at full throttle.

• Always hold the power cutter firmly, with both hands. Hold

SAFETY INSTRUCTIONS

Over exposure to vibrations can result in

!

Cutting technique

The technique described below is of a general character. Check information for each blade regarding individual cutting characte­ristics. (For example, a diamond blade requires less feeding pressure than a abrasive blade).

1.Support the work piece in such away that you can predict what will happen and so it will not pinch.

2.Always cut at full throttle.

3.Start cutting gently, do not force or squeeze the blade in.

4.Use a high blade speed.

5.Move the blade slowly backwards and forwards.

blood-vessel or nerve injury to persons suffering with blood circulation problems. Seek medical attention if you experience physical symptoms that can be related to over exposure to vibrations. Examples of such symptoms are numbness, lack of feeling, “tickling“, “pricking“, pain lack of or a reduction in normal strength, changes in the colour of the skin or its surfaces. These symptoms normally appear in the fingers, hands or wrists.

Water cooling

WARNING! Water cooling, which is only used for petrol-driven power cutters and when

!

Sharpening diamond blades

Blades can become dull when the wrong feeding pressure is used or when cutting some materials such as heavily reinforced concrete. To force a dull blade results in overheating and finally the loss of segments (part of the blade).

Sharpen against a soft material such as sandstone, silica or haydite brick.

Blade vibration

The blade can become out of shape (not round) and vibrate if a too high feeding pressure is used or if the blade is pressed into the work piece.

A lower feeding pressure ought to stop the vibration. Otherwise replace the cutting blade.

cutting concrete, cools the cutting blade and increases its service life as well as reduce dust formation (see the section ”

”). Among the disadvantages are

blades

difficulties at very low temperatures, the risk of damaging the floor and other sections of the building and risk for slippage.

Abrasive

Kickback

Kickback can occur very suddenly and with great force. If the following directives are not followed, it can result in serious or even fatal injury.

6.Use a small part of the blade’s cutting edge.

7.Only use the blade’s cutting edge when cutting.

8.Cut with the blade fully vertical – at right angles to the work piece.

WARNING! Under all circumstances avoid cutting using

!

the side of the blade; it will almost certainly be damaged, break and can cause immense damage. Only use the cutting section.

If the sector of the blade illustrated below is used for cutting the blade can start to climbing and kickback the power cutter upwards and backwards towards the user with immense force.

How to avoid kickback

1.Never cut with the segment illustrated in the diagram.

2.Keep a good balance and a firm foothold.

3.Use both hands and take a firm grip with the thumb and fingers around the handle.

4.Keep the work piece at a comfortable distance.

5.Use the cutter at full throttle.

6.Take care when inserting the blade in an existing cut.

7.Never cut above shoulder height.

!

8 – English

WARNING! Do not lean the blade to the side, this can cause the blade to jam or break with personal injury as a consequence.

8.Be alert to movement of the work piece or anything else that can occur, which could cause the cut to close and pinch the blade.
