WHEEL DRESSING TOOL (Fig. 6, 7)
After extensive use, the grinding wheels (3) will accumulate
in-ground metal build up. To clean the wheels detach the wheel
dressing tool (10) from the storage holder (Fig.6)
Rest the wheel dressing tool (10) on the tool rest approx. 5mm
from the grinding wheel (2). Switch on the grinder and wait a few
seconds until the grinding wheel reaches full revolution then
slowly move the dressing tool to gently touch against the
grinding wheel holding firmly with two fingers. Do not use
excessive pressure. (Fig.7)
CAUTION: Do not allow the grinding wheel and dressing tool to
touch before the grinding wheel has reached high speed as this
may cause the dressing tool to be flicked from your grasp
causing serious injury.
To ensure safety and reliability, all repairs should be
performed by an AUTHORIZED SERVICE CENTER or
other QUALIFIED SERVICE ORGANIZATION.
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.
WARNING!
After use, check the tool to make sure that it is in top
condition. It is recommended that you take this tool to a
RYOBI Authorized Service Center for a thorough cleaning
and lubrication at least once a year.
DO NOT MAKE ANY ADJUSTMENTS WHILE THE
MOTOR IS IN MOTION.
ALWAYS DISCONNECT THE POWER CORD FROM THE
RECEPTACLE BEFORE CHANGING REMOVABLE OR
EXPENDABLE PARTS (BLADE, BIT, SANDING PAPER
ETC.), LUBRICATING OR WORKING ON THE UNIT.
