Crown 4S - Pre-Operation Checklist; Pre-Start Procedures

Ecient and safe operation of the Mixer requires that
each operator reads and understands the operating
procedures and all related safety precautions outlined
in this section. A pre-operation checklist is provided
for the operator. It is important for both personal
safety and maintaining the good mechanical condi-
tion of the machine that this checklist is followed.
Before operating the Mixer and each time there-after,
the following areas should be checked o:
1. Gas Engine Units:
a. Check all uid levels: fuel, engine oil and
gearbox oil. Refuel or top up oil as required.
b. Check the tires and be sure that they are
inated to the specied pressure.
c. Check the tension and alignment of drive belt
when engaged. Tension or align as required.
d. Check the engine speed at maximum. Be sure
it is set to give a paddle rotation speed of 30-
35 RPM and a spiral rotation of 40-45 RPM.
e. Use the emergency stop switch to stop the
engine to be sure that it works. Repair or
replace if it is not functioning.
f. Lubricate machine per Maintenance Section.
g. Close and secure all guards, shields and
hoods.
2. Electric motor units:
a. Check the tension and alignment of drive
belt when engaged. Tension and align as
required.
b. Check gearbox oil level. Top up as required.
c. Check the tires and be sure that they are
inated to the specied pressure.

4.4 PRE-START PROCEDURES
All machines are sent from the factory in a special ship-
ping conguration to prevent spilling oil or gas. As a
result, the following items must be done prior to start-
ing the machine:
1. Gas engine powered units:
a. Fill the engine crankcase with its specied oil
(SAE 30W or 10W30 oil).
Refer to engine manual for oil specications if
operating in unusual temperature conditions.
b. Add SAE 80W90 oil to the gearbox.
c. Fill the fuel tank with regular unleaded gas. Do
not use an ethanol blend.
d. Start the engine and set the high idle speed
to give a mixing element rotation speed of 30
to 35 RPM for the paddles and 40 to 45 for the
spiral.
e. The machine is shipped with the drum tilt
lever pointing down or fastened to the safety
grill. Remove lever and turn it around so it is
pointing up. Tighten mounting bolts to their
specied torque.
f. Be sure the emergency stop switch is function-
ing properly.
IMPORTANT
The engine is supplied from the engine
manufacturer with the high idle speed set at
approximately 3500 RPM and no gas or oil.
As a result, the engine is not run when it is
mounted to the Mixer. It is the responsibility
of the customer to add oil and gas, start the
engine and reset the high idle RPM to the op-
erating range (Refer the Maintenance Section
for procedure).
IMPORTANT
Engine warranty is void if the
engine is run without oil.
d. Lubricate machine per Maintenance Section.
e. Close and secure all guards, shields and hoods.
