When using an alcohol cleaning solution. DO NOT use the HW-16.5 near a fire, open
flame or burning cigarette, pipe, cigar, etc. The vaporized alcohol in the vacuum exhaust
may ignite explosively.
**RULES FOR PROPER TUBE INSTALLATION**
Install the new tube in the tube holder with the slot at the 5:28 position. The rear felt pad
should touch the record more than the front felt pad.
Place record on platter and remove suction spring. Drop the tube assembly into the
suction hole. Loosen the setscrew in the stop ring so the vacuum tube drops onto the
record. Adjust the stop ring and tighten the setscrew so the stop ring is supporting the
vacuum tube.
The stop ring, not the suction tube, should absorb the downward force of the vacuum. If
the stop ring is not adjusted low enough the felt on the tubes will be damaged and the
tubes may be broken from the powerful suction forces.
