MANUAL LOWERING VALVE
N30-35ZDR and N35-40-45ZR
WARNING
Allow no on under or near the lift mechanism
or load during the manual lowering procedure.
Always verify that there are no obstructions
beneath the lift mechanism or load before at-
tempting to lower the mast manually.
The manual lowering valve is located on the main
lift pump manifold beside the hydraulic tank. The
manual lowering valve can be opened by turning the
valve knob counterclockwise to relieve pressure from
the hydraulic system. This can be used to manu-
ally lower the mast in case of malfunction or to re-
lieve pressure from the system before servicing the
hydraulics. If the mast leaks down during operation,
lower the mast and check that the knob is completely
closed (turn clockwise). Always close the manual
lowering valve after use. See Figure 6.

ure 7. This will open the valve and the mast will be-
gin lowering at a controlled rate. Push the load hold-
ing check valve knob in and turn it clockwise 180
until it pops back out to close. See Figure 7.
