SAFETY INSTRUCTIONS

Pull in

Pull in occurs when the lower part of the blade 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 power cutter 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.

Drying the blade

After using the blade with water cooling, let the cutter run for approx. half a minute so that the blade dries.

If a damp blade is stored it can become unbalance and cause damage.

Check the speed of the drive shaft

Use a tachometer regularly to check the speed of the drive shaft when the cutter is running at working tempera- ture and at full throttle without a load. The maximum speed is stated on the unit.

!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 power cutters 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 power cutter 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.

Power Cutter

Always handle the power cutter with care and store it with the blade removed.

Blades

All blades should be removed from the cutter after use and stored carefully.

Special care should be

taken with abrasive blades.

• Blades must be stored on a firm, level surface. If blades are supplied with a backing pad then a spacer should be used to keep them flat.

Avoid moisture and temperature extremes.

Remove the blades before the cutter is moved or transported.

Inspect new blades for transport or storage damage.
