10.13.3 Steering and Emergency
Hydraulic Pump
(S/N 7P0014 thru 9B0499)
The emergency hydraulic pump (3, Fig. 10.69)
performs three functions:
• When starting the engine, the emergency
steer pump supplies oil pressure as the
engine is being started;
• When oil pressure at the engine rises above
4 psi (0,3 bar), the emergency steer pump
ceases operation because the engine is
turning fast enough for the tandem pump to
supply sufficient hydraulic oil pressure for
forklift operation.
• If engine oil pressure again falls below 4 psi
(0,3 bar), the switch will close and the
emergency steer pump will resume operation
for as long as the battery has sufficient
charge.
