(1) Disengage the handle with the handle stop
(as shown in Figure 1).

(2) Feed grease by moving the handle to and fro.
* Pulling the handle to you sets the system to discharge operation and pushing it sets the system to sucking
operation.
(3) Grease feed operation is completed when the handle can no longer be pulled toward you. (The handle can
be pulled toward you until the stepped portion of the piston shown in Figure 1 touches the grand nut. Refer
to the detailed drawing.)
(4) When pushing the handle during operation, stop the handle when the handle touches the end of the handle
stop. (At this point, the handle is approximately parallel with the tank.)
(5) After completing grease feeding, push the handle until it comes into the status shown in Figure 2 for reducing
pressure (Figure 2). Under this status, the handle is locked to the handle stop. Then, stop pushing the
handle.
