1. Mount the APRM

®

-PC on the 4 bosses located on the inside cover

of the KBPC-240D using the four (4) # 6-32 screws provided.
Position the APRM so that the brake resistor is toward the bottom of
the cover.  Be sure not to trap any wires under the APRM mounting
bracket.  (See fig. 1.)

2. To mount the FWD-BRK-REV switch in the KBPC first remove the

rubber plug in the FWD-BRK-REV position by unscrewing the retainer
nut on the inside cover.  (See fig. 3 p. 5.)

3. Install the FWD-BRK-REV switch assembly into the front cover

making sure the key in the hole lines up with the keyway in the switch
bushing.  Be sure the hex nut supplied is installed at the base of the
switch bushing before inserting switch into the KBPC cover.

4. Install the rubber switch boot with integral hex nut over switch lever.

Switch should be in the stop position to facilitate installation.  Also,
the switch bushing threads should protrude no more than .25"
(6.4mm) or no less than .10" (2.6mm) through the front cover for
proper installation.  Tighten the switch boot so that the bottom seals
against the cover label.  Do not overtighten.
