MAINTENANCE INSTRUCTIONS
፴፧ 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.
፴፧ Never straighten or weld a damaged cutting blade.
፴፧ Inspect the cutting blades with the engine switched off at short, regular intervals for damage.
፴፧ (Detection of hairline cracks by means of tapping-noise test.) Beware the teeth are sharp.
፴፧ Clean the Hedge Trimmer at regular intervals and check that all screw and nuts are well tightened.
፴፧ Never service or store the Hedge Trimmer in the vicinity of naked flames to avoid fires.
፴፧ 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.
፴፧ Before grinding, be sure to secure the blade firmly and switch off the engine
and remove the spark plug cap.
፴፧ Wear gloves, protective glasses, etc.
፴፧ 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.
Checking and adjusting the idling speed
The cutting blade should not when the control lever is fully released.
፴፧ Idle speed should be set to 3,000 min
-1
.
፴፧ If necessary, correct it by means of the idle screw (the cutting blade must not
run when the engine is on idle).
Clockwise : for faster rate of revolution
Counter-clockwise : for slower rate of revolution
Check that there is sufficient difference between idling and clutch
engagement speed to ensure that the cutting tool is at a standstill while the
engine is idling. (If necessary, reduce idling speed.) If the tool still
continues to run under the idling conditions, consult your nearest authorized
service agent.
The clutch should engage at minimum 3,750 min
-1
.
Check the functioning of the I-O Switch, the lock-off lever, the control lever,
and the lock button.
Cleaning of air cleaner - Every 8 hours (Daily)
፴፧ Remove the air cleaner cover.
፴፧ Push the choke lever up (arrow), to prevent dirt particles from entering the
carburetor.
፴፧ Take out the sponge element, wash it in lukewarm water and dry it
completely.
፴፧ After cleaning, put back the sponge element and the air cleaner cover.
NOTE: If there is excessive dust or dirt adhering to the air cleaner, clean it
every day. A clogged air cleaner may make it difficult or impossible to
start the engine or increase the engine rotation speed which could
cause damage.
