1. Jog the motor until the pressing shoe (B) is
positioned between the inlet and outlet port (A).
2. Isolate the pump from the electrical supply.
3. Place a tray (A) under the drain plug in the
cover of the pump. Remove the drain plug (B).
Catch the lubricant from the pump housing in
the tray. Position the drain plug and tighten it
firmly.
4. Remove the cover (B) by loosening the
retaining bolts (A).
CAUTION
Too few shims, this means a too low com-
pression force on the pump hose, create a
loss of yield and slip or backflow. Backflow
results in a reduction of the life of the pump
hose.
