Using A Straight Grinder Continued
13) Check hoses and fittings regularly for wear. Replace if
necessary. Do not carry the tool by its hose. Ensure the
hand is removed from the on/off trigger when carrying
the tool with the air supply connected.
14) Take care against entanglement of moving tool parts
with clothing, ties, hair, cleaning rags, etc. This will
cause the body to be drawn towards the tool and can
be very dangerous.
15) Safe working practices and observe all relevant legal
requirements when installing, using or maintaining the tool.
16) Only install the tool when an easily accessible and easily
operable on/off switch is incorporated in the air supply.
17) Take care that the tool exhaust air does not
cause problems or blow onto another person.
18) Never lay a tool down unless the working attachment has
stopped moving.
PRE-START CHECKLIST (FIG. 1, PG. 2)
• Drain water from air compressor tank and condensation from
air lines. (Please refer to air compressor's operation manual.)
• Lubricate the tool. (Please refer to the "Maintenance" section
in the manual.)
• Select the required attachment. The mandrel of the attachment
must match the size of the collet on the air grinder.
WARNING: Risk of unsafe operation. Firmly grasp air hose
with hand when installing or disconnenting to prevent hose whip.
WARNING: Risk of bursting. Too much air pressure causes
a hazardous risk of bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories. The regulator output
pressure must never exceed the maximum pressure rating.

with the supplied 17mm wrench.
• Insert mandrel of an insert tool into the collet (A) and tighten by
fastening the collet nut (B) with the 17mm wrench.
