SAFETY INSTRUCTIONS

Water cooling

!WARNING! Water cooling is only used on petrol driven diamond chain saws when cutting concrete to cool the chain and increases its service life as well as reducing dust (see the section”Cutting equipment”).

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

Sharpening diamond chains

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

Sharpen against a soft abrasive material such as sandstone or brick.

Chain vibration

Excessive vibratione can accur if a too high feeding pressure is used or if the chain is pressed into the work piece.

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

Kickback

!WARNING!

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.

If the sector of the chain illustrated below is used for cutting the chain can start to climbing and kickback the cut-off saw 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 chain in an existing cut.

7. Never cut above shoulder height.

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 chain.

Pull in

Pull in occurs when the lower part of the chain is suddenly stopped or when the cut closes. (To avoid this see the section ”How to avoid kickback” and ”Pinching/rotation” below).

Pinching/rotation

Pinching occurs when the cut closes. The cut-off saw can be drawn suddenly and powerfully downwards.

How to avoid pinching

Support the work piece in such a way that the cut remains open during the cutting operation and when the cut is finished.

!WARNING!

If the speed is higher than that stated then the unit must be adjusted by an authorised service workshop before it is used.

Care and storage

General

Husqvarna’s cut-off saws are robust and durable. However, as they are used for high speed operations all servicing should be carried out on time and as specified, so that the cut-off saw always works effectively and safely.

Read this Operator’s Manual to determine which service routines you can carry out and ensure that all other service work is carried out by an authorised service workshop.

Always handle the cut-off saw with care and store it with the cutting equipment removed.

Cutting equipment

•The cutting equipment should be removed from the cutter after use and stored carefully.

•Inspect new cutting equipment for transport

or storage damage.

Once the work has been completed the diamond chain saw should be run with water pressure for at least 15 seconds to clean particles from the bar, chain and drive mechanism. Rinse off the machine with water.

It is recommended that the chain and bar are oiled to prevent corrosion if it is not to be used for some time.
