Dumping The Material - Toro CM-658H-S Operator's Manual

Preparing to Mix
DANGER
This machine is capable of amputating hands.
• Keep all bystanders a safe distance away
from the machine.
• Stop the machine immediately if any
people or animals enter the work area.
• Never place any part of your body into a
position that causes an unsafe operating
condition.
1. Read all the recommendations from
Operating Practices (page 4)
machine.
2. Ensure that the machine is on level ground and
the surrounding area is clear of obstacles.
3. Remove the machine from the tow vehicle.
4. Secure the machine from movement.
5. Use the handwheel to move the drum into an
upright, slightly tilted position to allow access for
pouring materials into the drum.
Note:
This position also allows the mixing
paddles to mix the materials more effectively.
6. Push the drum-tilt brake down to lock the drum
into position and avoid accidentally dumping the
material.
7. Start the engine. Allow the engine to warm up
at idle for 2 minutes; refer to
(page 25).
Important:
If you need to shut off
the machine quickly, use the engine
switch/speed-control handle (as equipped)
located on the cowl; refer to
(page 14).
8. Use the engine throttle lever/speed-control
handle (as equipped), to control the speed of
the engine and drum.
9. Close the engine cowl.

Mixing Concrete
Important:
Do not add more material than the
batch capacity for your specific machine model;
refer to Specifications (page
1. Ensure that the tilt brake is fully engaged and
that the drum is operating at full speed.
2. Pour water into the drum.
3. Add the concrete ingredients as follows:
•
If you are using pre-mixed concrete, add the
required amount of dry pre-mix.
•
If you are mixing sand, gravel, and cement,
add them as follows:
A. Add the required amount of gravel.
Note:
Adding water and gravel before
cement and sand allows the mix left in
the drum from the previous batch to be
tumbled off the drum and paddles and
into the next batch.
B. Add the required amount of Portland
cement.
C. Add the required amount of sand.
4. Allow the drum to turn while the mix reaches the
appropriate consistency.

Dumping the Material

Note:
When dumping a batch of material, leave the
engine running so that the rotating drum helps dump
the material.
1. Align a wheelbarrow or similar container of
adequate capacity in the path of the drum
opening.
2. While the drum is turning, firmly grasp the
handwheel with 1 hand.
3. Using your other hand, pull upward on the
drum-tilt-brake handle to release the brake.
4. Use both hands to slowly turn the handwheel,
allowing the drum to tilt in the desired direction
and dump the desired amount of material.
5. Turn the handwheel in the opposite direction to
return the drum into an upright position.
6. Push down on the drum-tilt brake to lock
the drum into position, avoiding accidental
discharging of concrete mix.
7. After dumping a batch of material, clean
the drum to prevent dried material from
contaminating the next batch of material; refer to
Cleaning the Drum (page
15).
