ABRASIVE LOADING

One filling of these models is called a LOADING. This consists of 3 assemblies... Each of which has 4 abrasive strips fastened at one end by a cloth loop. See abrasive loading price sheet.

INSTALLATION

With the nut and cap plate removed, install each assembly with the loop over a pin and the abrasive strips projecting between 4 adjacent brush holders (and brushes). With all 3 assemblies in place, the Head should appear as in photo at left.

Following this, replace the cap plate and the nut, leaving the nut loose until abrasive is wound in. Holding the back-plate stationary, grasp the outer edges of the cap plate and turn it in the direction that the head

will rotate when in operation. Turn until approximately 1⁄2” of abrasive remains beyond the brush tips.

At this point, tighten the nut... being sure the locking indentation in the cap plate falls between 2 of the brush holders. The nut should be finger tight.

Caution: Always be sure the ends of all brush holders are INSIDE the lip of the cap plate BEFORE operating.

 

ADJUSTMENTS

When fresh abrasive is required, loosen the nut sufficiently for the locking indentation to clear the brush holder. Turn the cap plate the opposite direction of that used to wind the abrasive in. Moving the lock one space (between brush holders) is normally sufficient to provide the needed extension. Tighten the nut. When a tool is started, extension of abrasive will occur either from centrifugal force... or as soon as work pressure is applied.

MOUNTING

These heads can be mounted on air tools, electronic tools, or flexible shaft machine by means of adaptors. BE SURE THAT TOOL SPEED DOES NOT EXCEED MAXIMUM SAFE RPM LISTED. These speeds, and the choice of adaptors offered, are listed on the reverse side. A minimum of 3⁄4 HP is recommended for models having abrasive 2” or wider.
