8.1.3 Pump Shut Off:
Pull pump lever rope and hold tight until
hammer stops (Fig. 18).
8.3.6
Figure 19
To regulate stroke, move remote lever any-
where in between wide open and shut off as
needed (Fig. 19). In general, the hammer is
stopped as in 8.1.3, but may also be stopped
by pulling back regulating lever completely.
8.1.4 Regulating:
8.2 BLEEDING THE FUEL PUMP
AT START UP
8.2.1 Raise piston carefully until the fuel pump
lever moves completely into the cylinder, and
then hold piston at this point.
8.2.2 Pull on pump lever rope with short rapid
strokes to activate pump element, thereby
bleeding out all of the air bubbles. DO NOT
continue to pull hard enough to inject fuel
into hammer, as flooding will occur.
8.3 FILLING AND BLEEDING
THE REGULATING CONTROL
SYSTEM (Fig. 18, 19, 20)
8.3.1 Open bleed valves on master control (A), fuel
pump regulator (B), and filler/bleeder unit
(C).
8.3.2 Close middle valve (D) on filler/bleeder unit.
8.3.3
8.3.4
8.3.5
8.3.7
Install filler hose (E) from filler/bleeder unit
into clean hydraulic oil supply.
Pump master control lever back and forth ra-
pidly until the unit is primed.
Continue to pump lever back and forth at a
slower rate until oil flows from bleeder valve
(C) without air bubbles.
The system’s lines are now full and the ex-
pansion reservoir in the master control must
be filled by closing valve (D).
Place allen wrench in pointer screw(F), loos-
en and move pointer to empty position, then
re-tighten.
