OPERATION
MAINTENANCE
To ensure safety and reliability, all repairs — with the
exception of the externally accessible brushes — should
be performed by a Ryobi Authorised Service Centre.
BRUSH REPLACEMENT (Fig. 13)
Your cut-off machine has externally accessible brush
assemblies (17) that should be periodically checked for wear.
Proceed as follows when replacement is
required:
Unplug your cut-off machine.
Failure to unplug cut-off machine could result in accidental
starting causing possible serious personal injury.
WARNING:
WARNING:
Remove brush cap (40) with a screwdriver. Brush assembly
is spring loaded and will pop out when you remove
brush cap.
Remove brush assembly.
Check for wear. Replace both brushes when either has
less than 6.5mm. length of carbon remaining.
Do not
replace one side without replacing the other.
Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.
Make sure brush cap is oriented correctly (straight) and
replace.
Tighten brush cap securely.
Do not
overtighten.
Once it reaches full speed slowly lower the handle of the
machine arm until the cut-off wheel comes in contact with
the material being cut. Continue to use steady and even
pressure to obtain a uniform cut through the workpiece.
Never force the wheel into the material being cut.
When the cut is complete, release the trigger and allow
the wheel to stop rotating before raising the wheel out of
workpiece.
Do not touch the cut material until it cools or you can be
burned. Failure to heed this warning could result in serious
personal injury.
To avoid serious personal injury, keep your hands at least
3 in. (76.2 mm) from wheel.
When cutting long pieces, support the opposite end of
the material with a roller stand or with a work surface
level with the machine base.
Never perform any cutting operation freehand (without
placing workpiece in the vise). Material will get hot during
cutting operation. Keep hands off of metal being cut to
avoid serious personal injury.
Before turning on machine, perform a dry run of the cutting
operation just to make sure that no problems will occur
when the cut is made.
Start the machine by grasping the handle and fully
squeezing the trigger. Allow several seconds for the
wheel to build up to full speed before letting it come into
contact with the material to be cut.
