Inspection and Maintenance (continued)
Replacing the Cut-off Wheel
1. Make sure the ignition switch is Off and
the engine is stopped.
2. Insert a 6mm hex wrench into the hole
in the belt guard to prevent the drive
shaft from turning. See Figure 29.
3.
Loosen the outer flange bolt with the
wrench and remove the bolt and outer
flange.
4. Before mounting a cut-off wheel, deter-
mine its arbor diameter. If necessary,
remove the snap ring from the arbor,
install the correct collar, then re-install
the snap ring.
WARNING!
Using the wrong size collar
may lead to failure of the wheel or the
unit and could result in serious injury.
5. Remove the old wheel and install the
new one. Make sure the inner bore is
properly set onto the collar.
Sharpening a Diamond Cut-off Wheel
While running the engine at low speed,
make about 10 passes at cutting a concrete
block or a soft brick. Keep the block
watered while sharpening.
Checking the Fuel Filter
WARNING!
KEEP AWAY FROM FIRE
OR EXCESS HEAT!
1. Remove the fuel filler cap.
2. Take the filter out from the fuel opening
by using a hooked wire. If the filter is
hard and clogged with debris, replace it
with a new one. See Figure 31.
CAUTION!
Make sure the fuel line is not pierced
by the hooked wire. The fuel line can
be easily damaged.
