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.
Blade adjustment
The blades will wear with long use. When you find that trimming is
not as good as when the blades were new, adjust them as follows
1. Turn nut x loose.
2. Screw y in with the driver lightly till it stops turning, and then
screw it back one quarter.
3. Turn nut x tight, holding screw y at the same time with a driver.
4. Lubricate the blades after adjustments above with light oil.
5. Start the engine and operate the engine throttle on and off for a
minute.
6. Stop the engine and touch the blades with your hand . If they are warm enough for you to keep your hand on, then you have made the
proper adjustment. If they are too hot for you to keep touching, give screw .y a little more turn back and repeat 5 to see if they are properly
adjusted.
NOTE:
Never fail to stop the engine before making the adjustment.
The blades have a slot around screw y y y y . In case you find dust in the end of any of the slots, clean it.
NOTE:
For enough time of blade stop (EN774), be sure to make the blade adjustment before operation.
