• Repeat recommended shift procedures with transmission in the
NEUTRAL position.
• Check system for loss of air and possible air leaks. Use manual
override procedures, if necessary.
• Also see heading “Standard transmission with Power Pump Shift.”
on page 93.
• Attempt to locate and repair leak(s). Leakage, if external, may be
detected audibly. Internal leakage is more difficult to detect and
requires disassembly.
WARNING!
DO NOT LEAVE THE CAB OR ATTEMPT TO PUMP UNTIL ALL THE
GREEN PUMP LIGHTS IN THE CAB AND PANEL ARE ILLUMINATED

Prime.
Note: Weekly
priming is rec-
ommended to
ensure proper
operation. See
Section 4 Pre-
ventive Mainte-
nance, heading
“Priming Sys-
tem Test” on
page 74.
Electric priming sys-
tem. • NO recommended engine speed is required to operate the elec-
tric primer. However, 1,000 engine RPM maintains the electrical
system while providing enough speed for initial pumping opera-
tions. Also see heading “Priming Valves” on page 41.
Inoperative priming
system or possible
clogged priming
pump. Note: Using lubricant on the vanes and vane slots during disas-
sembly and cleaning eventually causes a gummy residue to
develop, rendering the system inoperative. DO NOT lubricate
vanes or vane slots.
• Check the priming system by performing a “Dry Vacuum Test” per
NFPA standards. If the pump holds vacuum but primer pulls less
than 22” Hg, it could indicate excessive wear in the primmer.
• See Section 4 Preventive Maintenance, heading “Weekly” on
page 72. Also see Section 4 Preventive Maintenance, heading
“Annual” on page 79.
• Also see heading “Priming Valves” on page 41.
• Repair and/or replace accordingly.
Suction lifts too high. • DO NOT attempt lifts exceeding 22 feet (6.7 meters) except at low
elevation.
Blocked suction
strainer. • Remove obstruction from suction hose strainer.
• Thoroughly clean strainer screen.
Suction connections. • Clean and tighten all suction connections.
• Check suction hose and hose gaskets for possible defects - repair
and/or replace accordingly.
