Adjustments; Removal And Installation Of Wheel; To Remove; To Install - Ryobi C357 Operator's Manual

WARNING:
To prevent accidental starting that could cause possible
serious personal injury, assemble all parts to your cut-off
machine before connecting it to power supply. Machine
should never be connected to power supply when you
are assembling parts, making adjustments, installing or
removing wheels, or when not in use.
As mentioned previously your cut-off machine has been
factory assembled and adjusted. After extended use and
wear, the wheel will need to be replaced with a new one.
WARNING:
A 14 in. (356 mm) wheel is the maximum wheel capacity
of your cut-off machine. Never use a wheel that is too
thick to allow outer flange to engage with the flats on the
spindle. Larger wheels will come in contact with the wheel
guards, while thicker wheels will prevent the bolt from
securing the wheel on the spindle. Either of these
situations could result in a serious accident and can cause
serious personal injury.

REMOVAL AND INSTALLATION OF WHEEL

TO REMOVE

See Figure 5.
Unplug your cut-off machine.
WARNING:
Failure to unplug cut-off machine could result in accidental
starting causing possible serious personal injury.
Push down on machine arm and remove transport chain
from hook on motor housing to release machine arm.
Raise machine arm to its full raised position. Be cautious
when raising, machine arm is spring loaded.
Rotate lower wheel guard upward, exposing 8 mm socket
head bolt that secures abrasive wheel to wheel arbor.
Depress the spindle lock button and rotate bolt until
spindle locks, preventing shaft from rotating.
Using the 8 mm hex key provided, loosen and remove
bolt. Note: Bolt has right hand threads. Turn bolt
counterclockwise to loosen.
Remove outer washer, outer flange, spacer, and wheel.
Do not remove inner flange or inner washer. Removal of
these two parts are not required for wheel changes.
WARNING:
If inner flange or inner washer has been removed, replace
both before placing wheel on spacer and wheel arbor.
Failure to do so could cause an accident since wheel will
not tighten properly.

ADJUSTMENTS

TO INSTALL

See Figure 5.
Unplug your cut-off machine.
Failure to unplug cut-off machine could result in accidental
starting causing possible serious personal injury.
Inspect the replacement wheel for defects such as cracks,
chipping, and correct speed rating. If defects are found
or the speed rating is not greater than 3300 rpm, do not
use. Select another wheel.
Clean debris from the inner washer and inner flange.
Place new wheel over spacer, then place both on wheel
arbor against inner flange.
Clean outer flange, then align flats with flats on wheel
arbor and slide it onto arbor until it is flush against wheel.
Place recessed side of outer washer against arbor, then
insert socket head bolt into threaded end of wheel arbor.
Start threads and turn bolt clockwise to snugly tighten.
Depress the spindle lock button and rotate bolt until
spindle locks, preventing shaft from rotating.
Using the 8 mm hex key provided, securely tighten socket
head bolt. Note: Bolt has right hand threads. Turn bolt
clockwise to tighten.
Do not overtighten socket head bolt. Overtightening can
cause the new wheel to crack, resulting in premature
failure and possible serious personal injury.
