9. BLADE (Fig. 7)
The blade is made of pressed steel. It will be necessary to
reshape it frequently (with a grind wheel).
Ensure that it is always balanced (an unbalanced blade
will cause dangerous vibrations). To check for balance,
insert a round rod through the central hole and support
the blade horizontally. A balance blade will remain
horizontal. If the blade is not balanced the heavy end will
rotate downwards. Reshape the heavy end until the blade
is currently balanced. To remove the blade (1), unscrew
the blade screw (2) and replace any parts, which are
damaged. When reassembling, make sure that the cutting
edges face in the direction of the motor rotation. The
blade screw (2) must be tightened to torque 20 N.m.
WARNING: For service,
replace the blade with: MAKITA

WARNING: Disconnect the electric cord from the
power supply.
WARNING: Protect hands by using heavy gloves
or a rag to grasp the cutting blades when replace the
