Relieving Hydraulic System Pressure

CAUTION

Operate all machine hydraulic controls to relieve

system pressure and to avoid injury from pres-

surized hydraulic oil.

Before disconnecting or performing any work on the

Topdresser hydraulic system, all pressure in the hydrau-

lic system must be relieved.

To relieve hydraulic system pressure on Topdresser

1800 machines, turn tow vehicle key switch to OFF (en-

gine not running) and place the remote hydraulic valve

handle in the float position.

For Topdresser 2500 machines, turn tow vehicle key

switch to OFF and allow engine to stop. Make sure that

Topdresser control handle switch is in the OFF position
