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.

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.
