Using the machine
• This machine is designed to cut branches up to 28 mm thick. Cutting too thick branches or metal wires can not only break the blade teeth but also damage
the drive mechanism.
• When trimming leaves and thin twigs, guide the blades in a semicircle on the surface for a better finish.
• Running the engine at high speed with jammed blades can shorten the life of the clutch parts. If the blades are blocked by thick twigs, stop working
immediately and pull the unit away from the objects after stopping the engine. When cutting relatively thick branches, move the unit slowly back and forth
like a saw, and they can be cut to a fine finish.
• Note : When a new unit is used for the first time, grease may leak from the gear case during the first few minutes. This is excess grease there is no cause for
alarm. Wipe it off the next time you use the unit with the engine stopped.

Trimming techniques
Trim sides of a hedge first, and then the top.
Vertical cut (Fig. 7):
With the 2-sided blade model, use an arcing cut from the bottom upwards, then downwards
to use both sides of the blades.
Horizontal cut (Fig. 8):
For best results, tilt the blade slightly (5°-10°) towards the cutting direction. Cut slowly,
especially when cutting thick hedges.
WARNING ! Always follow the safety instructions. The hedge trimmer must only be used to trim hedges or small bushes. It is forbidden to cut other
types of material. Do not use the hedge trimmer as a lever to lift, move or break objects, or to attach to fixed supports. It is forbidden to attach tools
or attachments to the hedge trimmer that are not specified by the manufacturer. Do not use it to trim trees or cut grass.
MAINTENANCE
WARNING! Make sure that the engine has stopped and is cool before performing any service to the machine. Contact with a moving cutting blade
or a hot muffler may result in a personal injury.
Air filter (Fig. 9)
The air filter (1), if clogged, will reduce the engine performance. Check and clean the filter element in warm, soapy water as required. Dry completely before
installing. If the filter is broken or shrunk, replace with a new one.
Fuel filter (Fig. 10)
If the engine is running low on fuel, check that the fuel filler cap and fuel filter (1) are not clogged.
Spark plug (Fig. 11)
Failure to start and misfiring are often caused by a dirty spark plug. Clean the spark plug and check that the gap is in the correct range. When replacing the
spark plug, use the correct type (LD L8RTF).
• Note that using any spark plug other than those specified may result in malfunction or overheating and damage to the engine.
• To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn further with a socket wrench.
