Diamond Wheels - Bosch TG503 Operating/Safety Instructions Manual

Diamond Wheels

Do not use water when cut-
ting with this tool. The tool
is not designed for water and electric shock
may occur.
When a Tuckpointing Guard is used with a
thereaded spindle grinder (Bosch GWS series),
use only with a Type 41/1A or sandwich design
diamond wheel with a 7/8 in. arbor.
When the TG503 Tuckpointing Guard is used on
a grinder with a threaded spindle (Bosch GWS
series) and with a Type 1A/41 or a sandwiched
diamond wheel having a 7/8 in. arbor, then, to
mount the wheel, use only the special flange
and lock nut supplied with the TG503 Guard.
When a TG503 Tuckpointing Guard is used with
an X-Lock grinder (Bosch GWX series), use only
with X-Lock arbor sandwich-design diamond
wheels.
Dry diamond wheels stay cooler, clog less and
last longer.
1. Before running a cut-off machine, inspect
the cutting wheel for chips or cracks. Re-
place bad wheels immediately. New wheels
should be run in at no load for at least a
minute in the direction away from the pres-
ence of other people. Imperfect wheels will
normally break apart during this time.
2. An abrasive cut-off machine must NEVER
be operated without the attached guard
securely in place. The guard should be
rotated into the position where maximum
protection is provided for the operator
from sparks and wheel periphery.
