MAINTENANCE
TO EXAMINE THE BLADE(Fig. 24)
WARNING: ALWAYS stop the engine before you do work on the blade. The blade continues
to rotate after the throttle has been released. Make sure that the blade is fully stopped and
disconnect the spark plug cap before you start work.
CAUTION: For best results, keep the blade sharpened. Replace damaged blades immediately.
DO NOT use a mower with damaged blade.
• Examine the blade for cracks and other damage. A damaged blade must always be replaced.
• Always make sure that the blade is correctly ground and balanced. To examine blade balance, use a 7/8"
(22 mm) diameter steel bolt, pin or a cone balancer. Obey the instructions included with the balancer.
• DO NOT use a nail to balance the blade. The lobes of the centre hole are not centred.
• Move the blade onto an unthreaded part of the steel bolt or pin, and hold the bolt or pin parallel to the
ground. If the blade is balanced, it stays in the horizontal position.
If one of the two ends of the blade moves down, sharpen the heavy end until the blade is correctly
balanced.
NOTE:
The blades must be balanced after sharpening. DO NOT sharpen or balance the blade on your own.
Speak to an approved service workshop.
TO REPLACE THE BLADE
WARNING: Use gloves and/or wind the blade with a heavy cloth to prevent injury to your
hands.
CAUTION: Only use a replacement blade from an approved manufacturer. Using
a blade not approved by the manufacturer is dangerous and can cause damage to the product
and void the warranty.
1. Always disconnect the spark plug before you do maintenance.
2. Always empty the fuel tank before you put the product on its side. Empty the fuel tank by operating the
machine until the tank is empty.
3. Turn the product on its side. When the product is tilted, make sure that the air filter is always put in the
highest position. (Fig. 25)
