MAINTENANCE INSTRUCTIONS

-Turn off the engine and remove the spark plug connector when replacing or sharpening cutting tools, also when cleaning the cutter or cutting

-device or carrying out any maintenance.

Never straighten or weld a damaged cutting blade.

-Inspect the cutting blades with the engine switched off at short, regular intervals for damage.

-(Detection of hairline cracks by means of tapping-noise test.) Beware the teeth are sharp.

Clean the Hedge Trimmer at regular intervals and check that all screw and nuts are well tightened.

-Never service or store the Hedge Trimmer in the vicinity of naked flames to avoid fires.

-Always wear leather gloves when handling or sharpening the blades as they are sharp.

Blade sharpening

If the edges are rounded and do not cut well any more, grind off only the shaded portions. Do not grind the contact surfaces (sliding -surfaces) of the top and bottom edges.

Before grinding, be sure to secure the blade firmly and switch off the engine and remove the spark plug cap.

- Wear gloves, protective glasses, etc.

- An edge ground too much at a time or ground many times will lose its hardened layer. It becomes rounded and dull very quickly in use.
