■ INSTALLING THE BLADE (available as an option)
• Do not install or remove the blade while the engine
is in operation.
• Use ZENOAH’s genuine replacement blades and
metal fixtures when installing the blade.
• When installing or removing the blade, fix the
machine securely, and wear robust gloves.
• The blade turns counterclockwise (viewed from
the gear case). When using an inside-out blade,
check the direction of the blade before installing it.
In particular, if you install a chip saw in the wrong
direction, the chips might break and scatter.
INSTALLING THE METAL BLADE (SE11) (SE12)
1. Remove the blade mounting bolt which is temporarily
fastened in the gear shaft (and which can be loosened
by turning it clockwise as it is a left-handed bolt) and
the outer holder.
2. Put the blade on the blade rest plate with the blade
surface on which there is writing facing toward the
gear case, then fit the hole of the blade to the
projecting part of the blade rest plate correctly.
3. Put the outer holder into the gear shaft with its convex
surface facing toward the blade.
4. Put the bolt cover on the outer holder, stop the whirl of
the blade rest plate with the L-shaped round rod, and
put the spring washer into the blade mounting bolt
(left-handed bolt). Then, tighten the bolt firmly.
