APPLICATION OF SLURRY (CONTINUED)
III. PROCEDURES WHEN USING HOSES
Always pump clear water through the hose before pumping mulch. If the inside hose liner is dry, it will
dewater the mulch, causing the hose to plug.
A. PUMP TAKE-OFF SYSTEM OR HOSE REEL WITH REMOTE VALVE
1. Open recirculation valve, close discharge valve, and close remote valve at the end of the hose.
2. With the engine at low idle, engage (turn on) the slurry pump clutch. When stream is flowing
freely through the recirculation line, open the pump take-off valve.
The high pressure on the hose can exert strong forces, causing the
potential for the hose operator to lose control of hose or footing. The hose
will require additional hose holders when this operation occurs on slopes. Open the pump take-
off valve and the remote valve slowly and only after the hose operator is fi rmly positioned and
has fi rm control of hose. Failure to comply could result in minor personal injury, or product or
property damage.
3. With the engine running at approximately 3/4 speed, open the remote valve at the end of the
hose to discharge the load.
4. When finished spraying, close the remote valve, disengage (turn off) the slurry pump clutch,
and stop the engine. If using fiber mulch, retain as much water as possible in the hose by
elevating the hose ends or by coupling the hose ends together.
5. If another load is to be done, see RELOADING PROCEDURE. If finished for the day, follow the
clean-up procedure and flush out the hose.
The recirculation valve must be open when using a remote valve.
Failure to comply will result in serious injury or death.
B. EXTENSION HOSE SYSTEM - WITHOUT REMOTE VALVE
1. Connect the extension hose into the end of the discharge boom.
2. A person controlling the end of the hose directs a second operator at the machine to control the
slurry pump clutch and to adjust the engine speed.
Since the extension hose will be seeing the full output of the pump
with the recirculation closed, the equipment operator and individual at
the end of the hose should exercise extreme care when operating the unit on high pressure.
The high pressure on the hose can exert strong forces, causing potential for the hose operator
to lose control of hose or footing. The hose will require additional hose holders when operation
occurs on slopes. Engage the pump clutch only after the hose operator is fi rmly positioned and
has fi rm control of hose. Failure to comply could result in minor personal injury, or product or
property damage.
3. When hose operator is ready and the engine is at low idle, signal the second operator to
engage the slurry pump clutch and slowly increase the engine RPM until the desired discharge
pressure is reached.
4. When finished spraying, disengage the slurry pump clutch, stop the engine, and close the
discharge valve. If using fiber mulch, retain as much water as possible in the hose by elevating
the hose ends or by coupling the hose ends together.
5. If another load is to be done, see RELOADING PROCEDURE. If finished for the day, follow
clean-up procedure and flush out the hose.
