8. Do not overfill the drum. Do not exceed the mixer’s rated capacity.
9. Do not smoke while refueling the engine. Shut off the engine and allow it to cool before refueling. Do not spill
fuel.
10. Block/chock mixer wheels when mixing.
11. Use safety chains while towing mixer.
12. Keep the mixer in good operating condition. Loose or damaged parts are dangerous.

TOWING & SAFETY CHAINS
For transporting the mixer, slide the tow pole out as far as possible and insert the locking pin. Make sure drum
is locked in position and engine housing is closed and secured; cross the safety chains under the tow pole and
fasten them to the tow vehicle. (fig.1) When operating the mixer, slide the tow pole in and lock it in place.
NOTE! Safety chain length may need to be altered for proper connection to tow vehicle. Reposition the hooks,
DO NOT cut chain.
Allow enough slack to permit proper vehicle turning while keeping chains
snug enough to prevent tow pole from contacting the ground in case the
hitch uncouples.

PRIOR TO START UP
1. Examine the mixer carefully to make sure there was no damage during shipment or since the last use.
Report any damage immediately to the transportation company. Repair any damage before using the mixer.
2. Check the engine oil. Fill as required. Refer to the engine manual for oil specifications.
3. Fill the fuel tank with fresh, clean fuel. Refer to the engine manual for fuel specifications.
4. Grease all fittings as called out in the lubrication specifications.
5. Check hydraulic oil level in tank. The tank must be 75% full at minimum.
6. Replace hydraulic oil and filter every year or 300 hours of use. Refill with Lubsoil super hydraulic AW 32
or equivalent.
7. Check for free rotation of the mixer drum yoke by rotating the drum through one complete dump-charge-
dump cycle. Make sure no foreign objects or tools are in the drum before starting the motor.
8. Start the motor and check for smooth operation of the drum, ring gear, and pinion.
LUBRICATION
Use lithium based grade 2 multi-purpose grease.
Yoke Bearing Hangers:
Yoke bearing hangers are located on the yoke ends and are equipped with grease fittings. These bearings
should be greased weekly.
Wheel Bearings:
Grease wheel bearings once per year. Thoroughly remove old grease from bearings and spindle before
repacking. Pack bearings 1/2 to 2/3 full to prevent overheating.
Drum Tilt Brake Bearing:
The brake bearing casting is located near the front of the mixer and should be greased weekly.
Handwheel Bearing:
The handwheel hub bearing is located on the front of the mixer, behind the handwheel. This bearing should
be greased weekly.

STORAGE
For short term storage, clean the mixer and store in a dry place. If the mixer is not to be used for an extended
period of time, service mixer completely and store it in a dry place.
1. Refer to motor/engine instructions for storage instructions.
2. Cover exposed metal surfaces with a thin coat of SAE 30 engine oil.
3. Lubricate per instructions under LUBRICATION section.
GETTING READY FOR MIXING
Lay out forms for your concrete floor, patio, driveway, sidewalk, etc. The quality of concrete is directly related to
the quality of the cement paste. Calculate the proportions of your mix components (cement, sand and coarse
aggregate) according to the job specifications.
LOADING THE MIXER
Start the mixer. Refer to motor/engine instructions. Start drum rotating clockwise by activating hydraulic valve
lever. Pour about half of the water in the drum.
NOTE: The drum may leak slightly when first used. This will stop after a few batches. Add aggregate (gravel) first
then cement second and sand last. Then add remaining water as needed.
MIXING INSTRUCTIONS
1. Start the drum rotating clockwise by activating hydraulic valve lever.
2. Add
1/2water.
3. Add cement and two shovelful of coarse aggregate. The coarse aggregate will break up any lumps in the
cement.
4. Add remaining aggregate: crushed stone, pit-run gravel or sand.
5. Add remaining water as needed.
6. Mix batch for approximately one minute. Drum speed should be about 25 r.p.m. (NOTE: Mixing times may
change.)
UNLOADING THE MIXER
Allow the entire mixture to mix for one full minute. Do not stop mixer from rotating.
Hold the tilt handle and unlock the stop lever. Dump concrete to either side by rotating handwheel in the direction
required. (NOTE: Mixing times may change.)
CARE OF MIXER
It is important to keep the inside of the mixing drum free of hardened concrete. After discharging the last batch
of concrete each day, add a pailful of water and two shovelfuls of gravel to the drum. This will scour the inside of
the drum. Mix for about two minutes, discharge and rinse the drum with water. Never permit concrete to harden
on either the inside or outside of drum.
