MAINTENANCE
WARNING:
When servicing, use only identical Ryobi
replacement parts. Use of any other part
may create a hazard of cause product
damage.
GENERAL
Keep the bench grinder linisher clean.
Remove dust from working parts and beneath
the grinder frequently.
Make sure the bench grinder linisher operates
properly. Check screws, nuts, and bolts for
tightness.
EXTENSION CORDS
The use of any extension cord will cause
some loss of power. To keep the loss to a
minimum and to prevent tool overheating,
use an extension cord that is heavy enough
to carry the current the tool will draw.
A wire gauge size (A.W.G.) of at least 16 is
recommended for an extension cord 8 metres
or less in length. When working outdoors, use
an extension cord that is suitable for outdoor
use. The cord’s jacket will be marked WA.
WARNING:
Check extension cords before each use. If
damaged, replace immediately. Never use
tool with a damaged cord since touching
the damaged area could cause electrical
shock resulting in serious injury.
WHEEL DRESSING TOOL
Dressing a wheel is done to renew sharpness
or to true up the face of the wheel. Set the
work rest of the bench grinder at a slight angle
and brace the wheel dressing tool against it.
Do not make contact with the grinding wheel
until after you have turned on the motor and
the wheel is rotating at full speed. Press the
dressing tool slightly against the rotating
wheel until you get a bite, then move slowly
from side to side across the wheel. A small
bite and many passes is better than a big
bite and one pass. Work cautiously, hold the
dresser with force on the work rest. Do not
use excessive pressure against the grinding
wheel. Proceed slowly until you master the
technique.
WARNING:
Do not use excess force as this could
lead to the grinding wheel breaking and
serious injury.
