SHAPENING
Always keep the file or sharpener at an angle of 45° to
the blade, and:
• Always grind in the direction of the cutting edge.
• Note: files cut only in one direction; lift the file from
the blade when returning to start a new pass.
• Remove all burr from the edge of the blade with a slip
stone.
• Remove as little material as possible.
• Before refitting the sharpened blades, remove filings
and then apply grease.
Do not try to sharpen a damaged blade: change it or
take it to a Service dealer.
IMPORTANT
• Note that using any spark plug other than those des-
ignated may result in the engine failing to operate
properly or in the engine becoming overheated and
damaged.
• To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.
MUFFLER
WARNING
• Inspect periodically, the muffler for loose fasten-
ers, any damage or corrosion. If any sign of ex-
haust leakage is found, stop using the machine
and have it repaired immediately.
• Note that failing to do so may result in the engine
catching on fire.
INTAKE AIR COOLING VENT
WARNING
• Never touch the cylinder, muffler, or spark plugs
with your bare hands immediately after stopping
the engine. The engine can become very hot when
in operation, and doing so could result in severe
burns.
• Clean the cylinder fins with compressed air or a brush.
IMPORTANT
• If waste gets stuck and causes blockage around the
intake air cooling vent or between the cylinder fins, it
may cause the engine to overheat, and that in turn
may cause mechanical failure on the part of the
hedge-trimmer.

Point :
1. Keep the end corner sharp.
2. Round the root of the edge.
3. Do not use water when using a grinder.
• You need not to adjust the gap between upper blade
and lower blade as this product is designed to have
optimal gap when it is properly set up.

When mounting the blade, make sure to fasten the
spacer, washer and bolt, then fasten the nut.
