CHANGING THE GRINDING WHEELS
Your RYOBI bench grinder comes complete with an auto on
adjustable light (9) which allows you to illuminate the grinding
wheels and workpiece when operating in dark areas. The light will
automatically come on when the grinder is switched on. When
grinder is not in use, switch off the tool to avoid overheating of the
lamp.
When the globe is worn out and will no longer work gently remove
the bulb from the holder by pushing in and turning anticlockwise.
Use only RYOBI genuine replacement part 12 volt, 21 watt globe.
To replace gently push the globe into the insert and turn clockwise.
IMPORTANT: Do not use force as this could lead to the globe
breaking and serious injury.
The in-built coolant storage dip tray (5) allows you to cool
overheated workpieces. Simply pull out the tray and half fill with
appropriate coolant.
NOTE: The height and angle of eyeshields can be adjusted up and
down to the user's riquirement.

ASSEMBLY (Fig. 1, 2 )

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.
