Install adapter (2) between brake assembly (3) and heater frame (1), which is installed on the same
side of the heater frame as the brake lever.
Mount brake assembly (3) and adapter (2) to heater frame (1 ) with the two longer bolts (5) and wash-
ers (6) and (7).
Tighten kit bolts (5) only enough so that brake assembly is secure but adapter (2) is still loose.
Mount the opposite end of brake assembly (3) to heater frame (1) with previously removed bolts
(9) and washers (6) and (7). Tighten bolts.
Position brake lever (8) so that brake is disengaged and plunger (4) aligns and engages with lower
slot in adapter (2).
If required slide adapter forward or aft until plunger and adapter slot will align and engage. Tighten
bolts (5).
Position brake lever (8) so that brake is engaged. Check to see whether plunger (4) and adapter
slot align and engage properly.
If required, loosen bolts (5) and reposition adapter (2) until plunger (4) and adapter slot align and
engage properly. Tighten bolts (5).
Plunger (4) may have to be adjusted to achieve extra clearance for adapter (2). This can be done
by loosening the pin nut (4A) or plunger (4).
Unthread plunger from brake lever (8) until there is sufficient clearance. Tighten pin nut (4A) on
plunger (4).
