DISASSEMBLY, SHARPENING AND BALANCING OF THE BLADE
WARNING! Be sure to disconnect and ground the spark plug wire before working on the cutting disc
to prevent accidental starting of the engine. Protect hands with thick gloves or a rag to grip the
cutting blades.
CC All operations on the blade (disassembly, sharpening, balancing, reassembly and / or replace-
ment) require some knowledge and special tools. For safety reasons, go to a specialist center if you
do not have the necessary tools or experience.
1. Check that the blade is properly sharpened and firmly fixed to the clamp. A poorly sharpened
blade pulls the grass and causes the grass to turn yellow. A loose blade causes abnormal vibrations
and can be dangerous.
2. To remove the blade, hold it firmly while wearing thick gloves and unscrew the central screw in the
direction of the arrow (Fig.37).
Sharpen both cutting edges using a medium grinding wheel and check the balance using a bal-
ance knife.
We recommend that the blade be professionally sharpened and balanced at an authorized service
center.
CAUTION! Always replace a damaged blade; never try to fix it! ALWAYS USE THE MANUFACTURER'S
BLADE BEARING REPLACEMENT GUIDE.
When re-installing the blade, always follow the sequence shown, making sure that the wings of the
blade are facing the inside of the cutter and that the concave part of the spring cup (Fig.38A) is
pressed against the blade.
Tighten the fixing screw (fig.38B) using a torque wrench. The screw is tightened to the force de-
scribed in the specifications. If the knife (fig.38C) separates when disassembling the blade, make
sure the wedge (fig.38D) is firmly in its proper position.
CAUTION! Machine damage can be caused by operating the machine with an unbalanced blade.

ENGINE MAINTENANCE

ENGINE MAINTENANCE PRECAUTIONS
• Make sure the engine is turned off before starting any maintenance or repair. This will eliminate
several potential hazards:
-Carbon monoxide poisoning from engine exhaust - make sure there is adequate ventilation when
working on the engine.
- Burns from hot parts - allow engine and exhaust system to cool before touching.
- Injury from moving parts.
• Read the instructions before starting the engine.
• To reduce the possibility of fire or explosion, be careful when handling gasoline. To clean parts,
use only non-flammable solvent, not gasoline. Keep cigarettes, sparks and flames away from all
fuel-related parts.
• Remember that an authorized service dealer of our company knows your engine best and is fully
equipped for its maintenance and repair. To ensure the best quality and reliability, use only new
original parts for repairs and replacements.
