Lubrication Box
The C-30HDN model features a fully enclosed
lubrication box,
which utilizes the
"SPLASH"
method of lubrication.
Visually inspect the oil in the lubrication box (Figure 16) by making
sure the oil is at the correct operating level as indicated by the
dip stick. Also reference the oil level decal (Figure 17) adjacent
to the lubrication box.
Make sure the pump is on a secure
level surface when checking the oil
level inside the lubrication box.
NOTE
The pump engine should be turned
OFF, as explained in General Clean
Up Procedure.
After the sides of the hopper have
been cleaned, add a small amount
of water to the remaining concrete
in the hopper and hand mix.
2. Start the pump engine and pump the hopper all the way
down.
3. Disconnect the hose from the pump. Fill the hopper with water
and pump the remaining concrete out of the pump.
4. Open the hinged discharge cone and thoroughly wash out
all remaining concrete (sand-sediment) from the cone and
pump manifolds. Close the discharge cone and lock in place.
5. Take a sponge (2”x 4”x 6”) and soak it with water. Take the
hose that is disconnected from the pump and shake out the
concrete so that about 2 feet of it is clear. Insert the sponge
into the hose.
6. Reconnect the hose to the pump. Fill the hopper with water
and resume pumping. Run the pump approximately half
throttle. The sponge will be discharged at the end of the line
followed by clear water. At this point, the pump and lines will
be completely clean and ready for the next job.
Repeat steps 1 through 6 a few times
to ensure that the hose lines are
thoroughly cleaned.
NOTE
Sponge Clean-out Procedure
This section will explain the recommended procedure for using
a
sponge
to clean out the
hose lines.
NEVER use
muriatic acid
to clear the pump. Acid will dissolve
the chrome finish on the pumping cylinder.
NEVER use compressed air to clean out the lines.
When using a clean-out hook to clean out the rear of the redi-
mix truck, use a
safety chain
to secure the clean-out hook to
some solid part of the redi-mix truck to prevent the hook from
jumping off the redi-mix truck’s hopper. Run the pump at half
throttle.
1. After completion of the pour, pump the remaining concrete in
the hopper through the discharge line. Using a shovel, clean
the sides of the hopper.
CAUTION -
Checking Lubrication Oil Levels
The oil level must be
checked daily
to ensure adequate oil
level and oil cleaniness.
