ASSEMBLY

This concrete mixer is partially assembled at the factory. To assemble your machine, follow the below instructions.

Assembly requires two persons (recommended).

STAND

1. Slide the each wheel in each stub axle. Insert each split pin into the axle hole. Bend each of the side pins outward so they do not fall out. Attach the wheel caps.
   

2. With the frame lying on its side, attach the support legs. Align the 2 holes on the support leg with the frame holes as shown. (See Figure 1b, Illustration 1) Screw M8x40 hex bolt and washer into the upper hole. (See Figure 1b, Illustration 1). Insert M8x60 hex bolt through the lower hole, and secure with fiat washer, lock washer, and nut. (See Figure 1b, Illustration 2).
   

3. Turn the frame over and attach the axle bracket with wheels the same manner. (See Figure 1c Illustrations 1-2)
   

4. Make sure all bolts and nuts are tightened.

BOTTOM DRUM

1. Slide the motor support bracket on the shaft. (See Figure 2, Illustration 1)
2. Carefully place the bottom drum with support arm onto the side supports of the stand as shown. (See Figure 2, Illustration 2). The motor support bracket and support seat should slide into the side support channel on each side. The larger diameter shaft should be at the leg end of the stand.
3. On each side, line up the holes in the side support with those in the the motor support bracket and support seat, insert a M8x55 hex bolt from one side, then a flat washer, lock washer and nut from the other side. Tighten with a wrench. (See Figure 2, Illustration 3)

MIXING BLADES

Mount the mixing blades inside the bottom drum loosely as shown (See Figure 3, Illustration 1) Two holes are provided at the base of the drum into which a M8x20 screw may be inserted from the outside. A leather washer and a nut should be threaded on loosely on the inside. The leather washer should be placed under the blade down against the drum. (See Figure 3, Illustration 2)

Note the arrow labels on your mixer - one on the top drum and one on the bottom. If you have difficulty correctly positioning the mixing blades, temporarily mount the upper drum on the top of the bottom drum, and rotate the top so the two arrows align.

UPPER DRUM

1. Place the upper drum onto the bottom drum by aligning both the mounting holes, and the labeled arrows. (See Figure 4, Illustration 1 & 2)
2. Insert a M6x 16 cross headed screw into each mounting holes in the rim. Secure each screw from below with a lock washer and nut. Make sure the tightening process is carried out progressively. (See Figure 4, Illustrution 3)
3. Secure the mixing blades to the upper drum by inserting two M8x16 cross headed screws, from the outside through the holes in the drum.
4. A leather washer should be positioned inside between the drum and blade. Secure the mixing blade on the inside using a nut. (See Figure 4, Illustration 4)
5. Finally, ensure top and bottom mixing blade mountings are tight.

TIPPING BAR

1. Slide the locking plate over the large diameter shaft (at the "leg side" of the frame) with the rim facing inwards as shown. Insert two M8x25 bolts into the mounting holes, and secure each with a nut and flat washer. (See Figure 5a)
   

TRANSMISSION & MOTOR

Align the pinion shaft with the bushing sleeve in the transmission and slide into place. (See Figure 6, Illustration 1) Align the bolt holes in the frame bracket with the bolt studs and the holes of lower mount bracket in the motor case and slide into position. (See Figure 6, Illustration 2) Secure the motor case to the frame bracket using four M8 lock nuts. Secure the lower mount bracket to the frame with one M8x60 bolt, two flat washers and a lock nut. (See Figure 6, Illustution 3)

OPERATION

ELECTRICAL REQUIREMENTS

Confirm that you have a US Standard, 3 pin grounded, Type B, 15AMP (NEMA 5-15) outlet.

Check that the electric circuit is grounded, adequately protected, and that it corresponds with the power, voltage, and frequency of the motor.

ELECTRICAL CONNECTION

This mixer is double insulated to Class II protection and IP44D rated. The insulation will only remain effective if the original insulating parts are used for repairs and the spaces between the original insulation are maintained.

This mixer is double insulated to Class II protection and IP44D rated. To keep this rating, it is critical that the disassembly and reassembly of the electric control enclosure is performed properly. Only a qualified electrician is allowed to repair the enclosure of electric control.

Double insulation () eliminates the need for the three-pronged, grounded power cord and a grounded power supply system. Double-insulated devices can use either a two- or a three-pronged extension cord.

Do not connect either cord to the earth pin.

STAKE ON LEVEL GROUND

To secure your YARDMAX concrete mixer during operation, use two longer bolts or stakes through the holes in the front leg of the mixer stand to hold the mixer in place. (See Figure 7) Due to varying ground surfaces, these are not included. Choose the right type of bolt or stake for your surface type or call us for a recommendation.

DRUM TILTING

The spring-loaded tipping bar with locking lugs allows for tipping control of the drum (See Figure 8a), and can be locked in the following positions (see Figure 8b): Loading/Mixing - mortar, Loading/Mixing - concrete, Discharging, and Storage.

The drum is locked into the desired position by the lugs on the self-locating tipping bar, which lock into the slots on the locking plate on the mixer frame. (See Figure 8a) To tilt the drum, pull the tipping bar slightly toward you (away from the frame) to disengage the locking lugs. This allows the tipping bar to turn the drum in the desired direction.

To lock the drum in position, slightly release the tipping bar (towards the mixer frame) when rotating the drum. The lugs will slide and then lock into the nearest position on the locking plate.

LOADING

Completely unwind the extension cord. Connect it to the concrete mixer first before plugging in power supply.

Always start the motor before you start loading the drum. The mixer blades should be turning before you start adding the contents.

To avoid concrete or mortar sticking to the insides of the mixer drum, slowly pour material into the mixer steadily over the rim.

A built-in thermal protector is installed in the motor to prevent overheating, and will cool automatically as the motor cools.

For best results, always load the mixer in the following order:

1. Add the required amount of gravel into the drum.
2. Add the required amount of cement into the drum.
3. Add the required amount of sand into the drum.
4. Pour the required amount of water into the drum.

EMPTYING

Do not turn the mixer off (stop rotating arms) if you have content inside the bin. Always empty the drum completely with the mixer arms rotating.

CLEANING

Never put hands or limbs inside the drum while the mixer arms are rotating.

Thoroughly clean the mixer at the end of each days operation. Keep your mixer clean. The slightest trace of material left in the drum will harden and accumulate more each time you use it until the machine no longer will operate. Dried cement should be scraped out of the drum. Do not throw bricks into mixer drum to clean it out. Do not beat on the drum with a shovel, a hammer or other tools to break up accumulations of dried cement mix, as damage to the mixer may result. The drum may be scoured for approximately 2 minutes, using 1" gravel and water mixture. Then discharge the gravel/water mixture and hose down the drum assembly inside and out. The IP44D protection class construction of the concrete mixer enables you to hose down the drum assembly safely.

Do not pour or spray water directly over the motor cover, especially the openings in it.

Wipe off any external material on the motor cover. Do not use petrol, turpentine, lacquer or paint thinner, dry cleaning fluids or similar products. The use of chemical products or solvents may affect the properties of the cover which was made of high density polyethyiene PET.

MAINTENANCE

Ensure the extension cord is always unplugged before the motor cover is removed.

The drive belt maintains a constant, even tension provided by the spring-loaded jockey. No adjustment is needed other than an occasional touch of grease on the spindle.

The bearings are sealed for life.
