3 Wear-Plate/Wear-Ring Replacement Procedure

Warning

Extreme caution is needed when working in the hopper and waterbox. Use lock-out tag-out procedures. Al-

ways remove the ignition key and put it in your pocket or other secure place when working in the hopper and

water-box.

Note: The Western Shotcrete Equipment Warrior Shotcrete Pump, frame no.109 and higher are equipped

with an automatic accumulator discharging system* that will discharge the accumulator if the ignition key-

switch is in the off position or if the electrical system loses power. NOT if the engine stalls. (i.e. Engine runs

out of fuel, etc.) The operator should not rely solely on this system: he or she shall use the following precau

tionary procedure:

f) With the engine shut down, turn the ignition key-switch to the on position.

g) Turn the pump switch to the on position.

h) Repeatedly switch the swingtube from reverse to forward until the swingtube no longer shifts.

i) Toggle the pump switch to the off position.

j) Turn the key-switch to the off position.

Note: The electrical system must work properly for this procedure to work.
