Method of operation, Kickback, Cutting Tools

Method of operation

–Only use the Brush cutter/String trimmer in good light and visibility. During the winter season beware of slippery or wet areas, ice and snow (risk of slipping). Always ensure a safe footing.

–Never cut above waist height.

–Never stand on a ladder and run the Brush cutter/String trimmer.

–Never climb up into trees to perform cutting operation with the Brush cutter/ String trimmer.

–Never work on unstable surfaces.

–Remove sand, stones, nails etc. found within the working range. Foreign particles may damage the cutting tool and can cause dangerous kick-backs.

–Before commencing cutting, the cutting tool must have reached full working speed.

Kickback

–When operating the brush cutter, uncontrolled kickback may occur.

–This is particularly the case when attempting to cut within a blade segment between 12 and 2 o’clock.

–Never apply the brush cutter within a segment between 12 and 2 o’clock.

–Never apply this segment of the brush cutter blade to solids, such as bushes and trees, etc., having a diameter in excess of 3 cm or the brush cutter will be deflected at great force with the risk of injuries.

Kickback prevention

To avoid kickbacks, observe the following:

–Operation within a blade segment between 12 and 2 o’clock presents positive hazards, especially when using metal cutting tools.

–Cutting operations within a blade segment between 11 and 12 o’clock, and between 2 and 5 o’clock, must only be performed by trained and experi- enced operators, and then only at their own risk.

Easy cutting with almost no kickback is possible within a blade segment between 8 and 11 o’clock.

Cutting Tools

Employ only the correct cutting tool for the job in hand.
